In the world of food operations, maintaining impeccable standards of food safety is paramount. Ensuring that pests stay far away from food production facilities is an ongoing challenge, but recent advancements in technology are making this task more efficient and cost-effective than ever before. Remote pest monitoring systems are emerging as a game-changer, enabling food safety managers to stay on top of potential pest activity without having to travel. Beyond improving food safety, these systems also offer significant economic benefits.
The Traditional Pest Management Challenge
Traditionally, food safety managers have relied on periodic on-site inspections to detect and mitigate pest infestations. This approach is not only time-consuming but also costly, as it requires travel expenses, labor hours, and potential downtime for production facilities. Moreover, pests can multiply rapidly, making it essential to detect and address infestations promptly.
Enter Remote Pest Monitoring
Remote pest monitoring systems utilize cutting-edge technology to provide a real-time view of pest activity within food production facilities. These systems typically include strategically placed sensors, cameras, and data analytics tools. Here's how they work:
Sensor Networks: These systems employ strategically placed sensors that continuously monitor for signs of pests, such as temperature fluctuations, humidity changes, or even the presence of pests themselves.
Data Analytics: The data collected by the sensors is transmitted to a central hub where sophisticated algorithms analyze the information. This allows for the early detection of any pest activity or environmental conditions conducive to pests.
Alerts and Reporting: When the system detects unusual pest activity, it sends instant alerts to food safety managers, enabling them to take immediate action. Detailed reports and historical data are also available for analysis and trend identification.
Economic Benefits of Remote Pest Monitoring
1. Reduced Travel Costs
One of the most evident economic benefits of remote pest monitoring is the significant reduction in travel expenses. Food safety managers no longer need to visit multiple sites regularly, saving both time and money. This cost reduction is particularly crucial for large food production companies with multiple facilities spread across wide geographic areas.
2. Increased Operational Efficiency
Remote pest monitoring allows food safety managers to prioritize their efforts. Instead of spending hours on-site at each facility, they can focus on responding to alerts and addressing pest issues as they arise. This efficiency not only reduces labor costs but also minimizes production disruptions.
3. Timely Intervention
Early detection of pest activity is key to preventing infestations. Remote monitoring systems provide real-time alerts, allowing food safety managers to take immediate action. This proactive approach prevents the escalation of pest problems, which can lead to costly clean-up and damage control efforts.
4. Enhanced Documentation
Remote pest monitoring systems provide detailed records of pest activity, which can be invaluable for compliance and reporting purposes. This documentation can help food production facilities demonstrate their commitment to food safety standards during audits, potentially lowering insurance costs and protecting their brand reputation.
5. Reduced Product Loss
Pest infestations can lead to product contamination and spoilage, resulting in significant financial losses. By preventing infestations through remote monitoring, food production facilities can protect their inventory, reduce waste, and ultimately increase their bottom line.
Remote pest monitoring systems are revolutionizing pest management in food operations. Not only do they enhance food safety by enabling early pest detection and intervention, but they also offer substantial economic benefits. By reducing travel costs, increasing operational efficiency, facilitating timely intervention, and enhancing documentation, these systems are proving to be a cost-effective investment for food production facilities.
As technology continues to advance, the integration of remote pest monitoring will likely become an industry standard, ensuring safer food products and healthier bottom lines for years to come.

Wastewaterderived Data
Data from municipal wastewater treatment plants: An exploration of the utility to public health, environment, climate and security.
Municipal wastewater is said to mirror society. The water contains a mixture of most that occurs in a city. The food we eat, the medicines we take, the chemicals used in our homes and at work, bacteria, viruses and everything that washes off the streets when it rains, ends up at the local municipal wastewater treatment plant.
As Norway's largest wastewater treatment plant, Veas cleans wastewater corresponding to delivery from 770,000 people in Oslo, Bærum, Asker and Nesodden. Daily data from this water could provide near real-time data and trends that can be useful in managing the community.
Examples of data that can be extracted from wastewater are:
 - Health observatory based on trends of drug use or chemical exposure
 - Communicable disease tracking system (i.e. COVID-19)
 - Environmental surveillance system: release of pollutants in our environment
 - Defence and security: trace organic explosives detection in wastewater
NIVA and Veas are working on the development of an ecosystem consisting of members from multi-disciplinary sectors to exploit wastewater-derived data funded by the Regionale Forskningsfond Hovedstaden. At this stage, our main purpose is to show the potential of sewage chemical information monitoring (SCIM) technology to engage the potential partners from the public sector or research institute area (aim 2). Find below the aims of the ongoing project:
 1. Collect a selection of demonstration wastewater-derived datasets.
 2. Engage in targeted meetings/interviews with potential partners
 3. Identify unanswered questions for which wastewater may provide solutions
 4. Provide "ad hoc" analysis with demonstration dataset
 5. Work with the partner to formulate future collaboration and/or innovative research

Dartmouth researchers studying Vt. stream recovery
Research follows Tropical Storm Irene
Dartmouth College scientists studying the aftermath of Tropical Storm Irene in Vermont hope their work will help communities both predict and plan for future hazards.
Immediately after the 2011 storm, professors Frank Magilligan and Carl Renshaw used a National Science Foundation grant to conduct a rapid damage assessment. They are now a few months into a three-year, $345,000 grant to study the storm's longer-term effects, particularly in areas where overflowing streams washed away roads and houses.
The researchers are combining field analysis with aerial photography and other data to develop faster and more accurate assessment techniques that can be used to pinpoint potential trouble spots along streams. The goal is to give communities tools they can use to make scientifically informed planning decisions, rather than tell them what to do.

a day.
…but alternatively,
Even a 140lb goat makes 5 grams a day in its liver and up to 60 grams a day when sick or injured
So now it's up to 100 grams. OK, if I get scurvy I'll eat a sick goat.
Vitamin C has been around for millions of years.
As I pointed out above, we (humans and our ancestors) have had about 60 million years to adapt to being unable to make vitamin C. We have developed very efficient ways of utilizing very small amounts, partly through mechanisms to concentrate ascorbate in tissues that require large amounts, up to 100 times higher than plasma levels. Uric acid, which most other animals metabolize to the more soluble allantoin, substitutes for many of ascorbate's roles in humans.
Goats make 100 GRAMS in their liver when sick.
Ignoring the exaggeration, that's because they break down uric acid to allantoin, so they don't have the benefit of its antioxidant properties and, I believe, they are unable to regenerate and concentrate ascorbate in specific tissues as efficiently as humans and some other primates.
Liver is a good source of vitamin C, by the way. Fried lamb liver contains more vitamin C, gram for gram, than many fruits (grapes, apricot, plums, watermelon, bananas, crabapples…).
Goats make 100 GRAMS in their liver when sick.
And how does that work out for the goats? Are goats never sick? Do they recover more quickly than animals that don't produce "100 GRAMS" (or more realistically, between 2 and 13 grams) of ascorbate a day? Are they immune to viral infections?
From Calhoun's FB page:
You are what you eat. As your body digests food, it becomes the red blood cells that becomes the cells of your body.
Here endeth the lesson.
Now I am wondering how this Health Coaching business works for Richard Calhoun. No doubt there are some people willing to pay a retainer to receive dietary and supplement advice he's scraped from Null and Mercola and Miley Adams' websites, because that way it's more authoritative then reading that advice *directly* for free… but how many?.
Goats make 100 GRAMS in their liver when sick.
The implication is that they make extra ascorbate to combat their sickness, which seems plausible, since white blood cells (and other tissues and organs) require extra ascorbate when fighting infections.
However, I wonder if it is as simple as that. Maybe high ascorbate is a symptom of sickness, not an attempt to cure it. High blood glucose is a symptom of diabetes, but we don't assume that a diabetic's body is increasing glucose levels to combat the diabetes. In fact cells are starved of glucose because it can't get into them without insulin; 'starving in the midst of plenty' as it is sometimes put. Restoring low glucose levels to normal is beneficial; hyperglycemia is damaging. Could something similar be happening in sick animals?
Is it possible that infection disrupts the normal feedback mechanisms that control ascorbate synthesis? Ascorbate is made from glucose, which sick goats presumably require plenty of; perhaps converting it to ascorbate most of which is promptly excreted in the urine is a bug, not a feature.
The hypothesis that we require similar amounts of ascorbate when we are sick depends on a number of assumptions, at least some of which are undoubtedly wrong.
I confess that my expertise in goat physiology is limited to Bengali-style curry.
Ascorbate is made from glucose, which sick goats presumably require plenty of; perhaps converting it to ascorbate most of which is promptly excreted in the urine is a bug, not a feature.
Like a too high a fever in humans? Sounds plausible. I'd call it a *hypothesis*. Perhaps it could have started from some past and pathogen that also relied on glucose — 'starve a cold'? Do any microbes also use glucose?
I don't know goat biology but I've a friend who had a goat. A very friendly goat that grew up with a very friendly chow dog. While that thing would not eat tin cans, he would make off with my Copenhagen only to *sometimes* bring it back… He didn't seem to like it. He'd eat a dollar bill though. The most unique thing I remember about *Lawrence* was how doglike and personable he'd become — They're pretty smart when you get to know them. If one went to take a leak behind the woodpile then the goat was there beside you actually hiking his leg just like a dog and peeing; Always careful to hike opposite the humans and looking up and seeming to 'grin' as he did so.
The primary and indeed only source for this story seems to seems to be Chatterjee's work in the 1970s — he measured a range of 2,280 – 13,300 milligrams.
Turns out that I got that wrong. Chatterjee published results of test-tube vitamin-C production from "incubat[ing] tissue homogenates with precursors of ascorbic acid", for a number of mammals.
I don;t know whether it was Chatterjee's idea to extrapolate from homogenised enzymes up to total production from a functioning goat liver in situ (Science hasn't digitised its back issues as far back as 1973); or Stone's idea in his 1979 paper (says "13,000 mg"); or if Patrick Holcroft (a familiar name) calculated his own extrapolations in 1997 ("2,280 – 13,300 mg").
(that goat range is at the high end of the scale; cats, for instance, are about 1/10 as productive).
_URL_
Along the way someone decided that sick goats must generate more Vtamin C — no experiments were needed — and from then on, the main requirement for pulling an estimate out of the air has been that it must exceed previous estimates.
is a bug, not a feature
Like too high a fever in humans?? Sounds like a hypothesis. Perhaps some remaining response to a past pathogen that eats glucose — 'starve a cold'? Do germs use glucose?
I had a warm and affectionate story about *Lawrence* the friendly goat that would actually hike his leg like a dog and pee next to one (never on him) when visiting behind the woodpile. He'd look up at you the whole time seeming to *grin*. He grew up with my friends' friendly chow dog and would not eat tin cans. Though he would run off with my Copenhagen… sometimes bringing it back. He didn't seem to like it. He'd eat dollar bills though. Other than that, I don't know goats.
(I'd posted earlier but am truely heavily moderated or I had noscript blocking the site… so )
doug,
From Calhoun's FB page: You are what you eat. As your body digests food, it becomes the red blood cells that becomes the cells of your body.
That's pure Robert O. Young. I'm not sure anything can prepare you for this webpage, where Young claims, among other equally untrue things, that red blood cells are made in the intestine, and that having any enzymes in your GI tract is bad – your food should digest itself, apparently (he literally does claim this).
I had wondered in the past how Young reconciled his claim that our stomachs should be alkaline with the fact that gastric enzymes work at an optimum pH of about 3 (I had to find the optimum pH of pepsin for one of my practical biochemistry exams). Now I know, he neatly side-steps the problem by denying these enzymes exist.
Either Young is some sort of performance artist, a brilliant*, though utterly immoral, con man, or he is raving bonkers. What kind of person makes up their own 'New Biology' and makes up his own facts to fit his grand theory?
* Brilliant in terms of parting marks from their money, I mean, and apart from getting arrested, of course.
What kind of person makes up their own 'New Biology' and makes up his own facts to fit his grand theory?
ALL OF THEM.
Krebiozen,
Thanks. I had a suspicion the claim had come from someone other than Calhoun. I've seen bits and pieces of Young's nonsense, but I didn't know of his beliefs about digestive processes and cell generation. I'd never been to his web site before. Yeesh! I feel like I should be paying someone to run a plumber's snake through the intertoobz.
I really do wonder how some of these people are "made." Sometimes I think that a large fraction of them know that what they are pushing is nonsense, but they have come to realize that becoming rich and famous by gulling the rubes is far easier than doing it by being really good at "conventional" things. Toss in credulous fools like Oprah to promote them, and there is no turning back.
Calhoun, I fear, is probably one of gulled rubes.

When you think of traditional corporate video production there is a stereotype of the video being boring and dull. Now in the past this was correct. Corporate video production used to not be very engaging, simply a tool for brand awareness.
However, the video production landscape has changed. Video is now more engaging and the key to moving your audience, through appealing to their emotions.
Through creative and experimental ways, the increase in businesses connecting to an audience on an emotional level has become highly prevalent. Today authenticity and personal corporate videos are rewarded over the standard facts and figures of a product or service.
How Effective Is Emotion In Corporate Video Production?
Using the right balance of emotion throughout the corporate video production process makes for a compelling watch. If you can bring tears to an audience members eyes or make them laugh you connected with them.
And if you connected with them on a human level chances are they are going to converse with others about your video and share it online. This is what you want, to improve your reach but also to start a conversation.
Humans are social creatures and the art of storytelling is to create something that resonates with people, something they can relate to. The greater the emotional impact, the greater the success rate of your video.
What Are The Most Effective Emotions To Evoke?
With different business models different emotions to target will be relevant. You first have to consider what type of emotions you wish to elicit in a consumer. Positive emotions like happiness tend to evoke a more positive response.
Content Marketing Agency Fractl created a study analysing what the most popular emotional responses revolving around viral content.
Their study found the top ten emotional responses to viral content were:
 1. Happiness
 2. Surprise
 3. Admiration
 4. Satisfaction
 5. Hope
 6. Love
 7. Happiness for
 8. Concentration
 9. Pride
 10. Gratification
The bottom emotional responses to viral content were:
 1. Hate
 2. Reproach
 3. Resentment
 4. Gloating
 5. Shame
 6. Anger
 7. Remorse
 8. Depression
 9. Annoyance
 10. Disappointment

'The British Vampire's Slavic Roots'
Fri, January 22, 2010 • 3:00 PM • Tom Lea Rooms, HRC 3.206
Thomas Jesus Garza, Texas Language Center
Bram Stoker can be credited with creating the modern Western vampire, but his vision of the legendary monster would not have been possible without the historical accounts of real-life figures from Eastern Europe. Tom Garza will reveal the origins and history of the vampire in Europe and Britain from the nineteenth century through the twentieth. The myth pervades popular culture to the present day.
Thomas Jesus Garza is University Distinguished Teaching Associate Professor of Slavic and Eurasian Studies and the Director of the Texas Language Center. He received his Ed.D from Harvard University in foreign language education. He teaches courses in Russian language, culture, and literature, including a popular course on the history of the vampire. He is working on a book on Russian and Mexican contemporary film.

Consider $G = GL_n( \mathbb{Q}_p)$ and $K = GL_n( \mathbb{Z}_p)$, or more favorable replace $ \mathbb{Q}_p$ by a non archimedean field and $\mathbb{Z}_p$ by the ring of integers.
Note that the space $G //K$ is discrete, since $K$ is open and closed in $G$.
Given a Haar measure on $G$, I can prove that there exists a unique (discrete) measure on $G//K$, such that $$ \int\limits_{G} f(g) d g = \sum\limits_{x \in G//K} w(x) \int\limits_{K \times K} f(k_1 x k_2) d k_1 d k_2.$$
How can $w$ be expressed, if we pick a representative $x = diag( w^{k_1}, \dots, w^{k_n})$ for a uniformizer $w$?
Perhaps easier, but equivalent what is the ratio: $vol_G (K xK)/ vol_G(K)?$
(More out of curiousity: How is the Plancherel measure related to this?)
share|improve this question
You are dealing with the integral formula for the Haar measure on $G$, associated with the Cartan decomposition $G=KAK$. Since the Plancherel measure lives on the dual object $\hat{G}$, I don't see any obvious relation between the two. – Alain Valette Dec 17 '11 at 22:05

The measure of $KxK$ is a classical computation that may be found in: Macdonald "Symmetric Functions and Hall Polynomials" (Oxford Mathematical Monographs), more precisely in Chapter V: The Hecke ring of ${\rm GL}(n)$ over a local field.

This is very useful, thank you. I will delete my response as obsolete. The final answer is (2.9) on p.298 of Macdonald's book. – GH from MO Dec 17 '11 at 18:05
My copy of Mc Donalds (1979) has it on pg. 162! Thanks to both of you. – Marc Palm Dec 18 '11 at 10:02
Depending on taste, one might also find appealing or helpful the description of this in terms of the Iwahori-Hecke algebra, with affine Weyl group and affine cartan decomposition $G=\bigcup_w BwB$ where $B$ is the Iwahori. Among other features, this does give a way to inductively determine the measure of $BwB$, once the measure of $B$ is normalized, because there is a precise cell-multiplication rule $BwB\cdot BsB=BwsB$ when the length of $ws$ is strictly greater than that of $w$, and $s$ is one of the affine reflections generating $W$. That is, the length in $W$ is equivalent to knowing the measure of the Iwahori coset.
(Inevitably, surely MacDonald's discussion does something equivalent to this, but I don't remember, and I don't have a copy accessible to me.)
share|improve this answer
I checked the other answer, because it directly answers my question, but your suggestion seems a lot more suitable for my purposes than the ''naive'' KAK decomposition I was aking about. Do you have a reference for this? Thanks a lot for mentioning this. – Marc Palm Dec 18 '11 at 10:04
_USER_, In my "Buildings and Classical Groups" book, (math.umn.edu/~garrett/m/buildings/book.pdf) chapter 5 exactly treats this: it is simply the BN-pair (with corresponding Bruhat decomposition, etc) attached to the affine building. Probably any book on buildings mentions this at some point. In some sources, the cell multiplication rule is an "axiom". In my chapter 5 I prove that it follows from the building properties. – paul garrett Dec 18 '11 at 15:01
So just to confirm that I understand what you are saying notationwise: In your notation $B$ is the pullback of the Borel subrgoup $B'$ in $GL(n, o/p)$ along the projection $GL(n,o) \rightarrow \GL(n, o/p)$ and $w$ runs through the normalizer of all diagonal matrices $M$ (=affine Weyl group $MW$?). This is called affine Cartan decomposition? What is $N$ in the $BN$ pair, if $B$ is the Iwahori? ($N=MW$?) I am rather fine with using axioms, but it usually gives me a headache to verify that they hold for specific examples. – Marc Palm Dec 18 '11 at 16:53
_USER_: Yes, in this situation, $B$ can be described as the inverse image in $GL(n,o)$ of the Borel in $GL(n,o/p)$. Yes, the affine Weyl group is normalizer of diagonals, modulo diagonal unit matrices. In my book/notes I verify (as did Bruhat and Tits ages ago, maybe it's in Bourbaki Lie ch. iv-...?) that the affine building for $SL(n,k)$ can be constructed via homothety classes of lattices. Then the building properties prove an abstracted Bruhat decomposition. One can also prove, following Tits, that the Coxeter-group property follows from the building set-up. – paul garrett Dec 18 '11 at 18:22

Who Is Robert Lucas?
Robert Emerson Lucas Jr. is a New Classical economist at the University of Chicago, renowned for his prominent role in developing microeconomic foundations for macroeconomics based on rational expectations. He won the Nobel Prize in Economics in 1995 for his contributions to the theory of rational expectations.
- Robert Lucas is a New Classical economist and long-time professor at the University of Chicago.
- Lucas is best known for his development of rational expectations theory and the eponymous Lucas Critique of macroeconomic policy.
- Lucas received the Nobel Prize on 1995 for his contributions to economic theory.
Understanding Robert E. Lucas Jr.
Robert E. Lucas Jr. was born the eldest child of Robert Emerson Lucas Sr. and Jane Templeton Lucas in Yakima, Washington, on Sept. 15, 1937, Lucas received a Bachelor of Arts in History from the University of Chicago in 1959. He initially pursued graduate studies at the University of California, Berkeley, before returning to Chicago for financial reasons. In 1964, he earned his PhD in economics. Initially, he believed his academic life would center around history, and he only continued his economic studies after reaching the conclusion that economics is the true driving force of history. Significantly, Lucas claimed to have studied economics for his PhD from a "quasi-Marxist" point of view, based on Marx's idea that the vast, impersonal forces that drive history are largely a matter of economics.
Lucas became a professor at Carnegie Mellon University at the Graduate School of Industrial Administration, before returning to the University of Chicago in 1975. In 1995, Lucas was awarded the Nobel Memorial Prize in Economics for developing the theory of rational expectations. He is currently professor emeritus at the University of Chicago.
Lucas is most well known for his contributions to macroeconomics including the development of the New Classical school of macroeconomics and the Lucas Critique. Lucas has spent much of his academic career investigating the implications of the rational expectations theory in macroeconomics. He also made important contributions to theories of economic growth.
Lucas built his career applying the idea that people in the economy form rational expectations about future events and the impact of macroeconomic policies. In a paper in 1972, he incorporated the idea of rational expectations to extend the Friedman-Phelps theory of long-term vertical Phillips Curve. A vertical Phillips Curve implies that expansionary monetary policy will increase inflation, without boosting the economy.
Lucas argued that if (as is assumed in microeconomics) people in the economy are rational, then only unanticipated changes to the money supply will have an impact on output and employment; otherwise people will just rationally set their wage and price demands according to their expectations of future inflation as soon as a monetary policy is announced and the policy will only have an impact on prices and inflation rates. Thus not only (per Friedman and Phelps) is the Phillips Curve vertical in the long run, it is also vertical in the short run except when monetary policymakers can make unannounced, unpredictable, or truly surprising moves that market participants are unable to anticipate.
The Lucas Critique
He also developed the Lucas Critique of economic policymaking, which holds that relationships between economic variables observed in past data or estimated by macroeconometric models are not reliable for economic policymaking because people rationally adjust their expectations and behavior based on their understanding of the impact of economic policy. The expectations about economic conditions and policy that shaped consumer, business, and investor behavior during the periods from which past data are drawn often will not hold once conditions and policies change.
This means that economic policymakers cannot reliably hope to manage the economy by tinkering with key variables, such as money supply or interest rates, because the act of doing so also changes the relationship between these variables and the variables that represent the targeted outcomes, such as GDP or unemployment rates. Thus the Lucas Critique argues against activist macroeconomic policy aimed at managing the economy.
Economic Growth and Development Economics
Lucas also made contributions to endogenous growth theory and to unifying growth theory (which applied mostly to growth in developed economies) with development economics (applied to less developed economies). This includes the Lucas-Uzawa model, which explains long-run economic growth as dependent on human capital accumulation, and the Lucas Paradox, which asks why capital does not appear to flow to regions of the globe where capital is relatively scarce (and thus receives a higher rate of return) as neoclassical growth theory would predict.

Create and run jobs as a non-root user
This document describes how to create and run a Batch job as a non-root user.
By default, Batch executes runnables as the root user. If you want Batch to execute runnables as a non-root user—for example, to run an application that doesn't allow root users or to meet security requirements—create a Batch job that uses OS Login. When you enable OS Login in a Batch job, OS Login configures a user account for you on the VMs that your job runs on. All runnables in the job are then executed by your user account on the VM instead of by the root user.
Before you begin
 1. If you haven't used Batch before, review Get started with Batch and enable Batch by completing the prerequisites for projects and users.
 2. If you haven't done so already, enable the OS Login API by running the following command:
 gcloud services enable oslogin.googleapis.com

 3. To get the permissions that you need to create and run a job as a non-root user, ask your administrator to grant you the following IAM roles:
 For more information about granting roles, see Manage access to projects, folders, and organizations.
 You might also be able to get the required permissions through custom roles or other predefined roles.
Create a job that runs as a non-root user
Create a Batch job that runs executables through your own user account by doing the following:
Use the Google Cloud CLI or REST API to create a job that includes the runAsNonRoot field set to true in the main body of the JSON file:
"runAsNonRoot": true
For example, a job that runs executables as a non-root user would have a JSON configuration file similar to the following:
{
 "taskGroups": [
 {
 "taskSpec": {
 "runnables": [
 {
 "script": {
 "text": "echo Hello World! This is task $BATCH_TASK_INDEX executed by $(whoami)."
 }
 }
 ]
 },
 "taskCount": 3,
 "runAsNonRoot": true
 }

Personalizing your connection to QA/Production environments with SecureCRT
January 6, 2014 Leave a comment
The trouble with production/QA environments is that you can rarely change them to fit you personal preferences, and usually you use a common user to access them.
If you are working on Windows and using SecureCRT to connect to Linux/Unix machines (and if not – ask yourself why …) you can personalize any connection to QA/Production environments by telling SecureCRT to perform automatic login activities – this without effecting how the machine behaves for other users.
By personalization I am referring to the definition of your personal aliases etc.
How to do it:
 1. Download this VBScript to your computer, and place it somewhere (e.g. C:\Utils\SecureCRT\Scripts)
 2. Find a connection you want to effect in SecureCRT and open it's properties
 3. Navigate to Connection -> Logon Actions
 4. Check the Logon script checkbox and type the path to the file defined at the beginning (e.g. C:\Utils\SecureCRT\Scripts\EnvironmentPersonalizer.vbs)
Every time you login – SecureCRT will run that script.
What the script does:
The way this scripts works is that it waits for something to happen on the screen and then sends commands.
Example:
objTab.Screen.WaitForString("$") // Wait for the prompt
objTab.Screen.Send "bash" & vbcr // Switch to a BASH shell
objTab.Screen.Send "clear" & vbcr // clear the screen
objTab.Screen.Send "alias ll='ls -lart'" & vbcr // Alias 'll' to be 'ls –lart'
You can find a few more utility scripts on my Github Repository – _URL_
Note: Take great care when effecting anything on production environments – don't do anything that will effect how the environment behaves for other people (like changing the .bash_profile for example)

Jar scanning utility – find a class within all jars (Unix/Linux)
March 28, 2013 Leave a comment
Every so often I need to figure out which jar(s) contain a certain class so I can figure out why an application acts the way it does – either since a class is missing in some environment or since the wrong class was loaded into the classpath.
When that happens, I use the following script. I saw it once in a company I worked at, and then again in another company.
I modified it slightly, but the credits do not go to me, they go to the anonymous person who wrote the initial code.
The script is available for download on GitHub.
Or you can simply copy it from here:
#!/bin/tcsh -f
if ( $#argv < 2 ) then
 printf "Scans all the JARs in the specified directory for classes matching the specified string\n"
 printf "Usage: $0 <dir> <class-name-pattern>\n"
 printf "Example: $0 . Exception\n"
 printf 'Example: '$0' $JAVA_HOME/lib "com\/sun\/.*action"\n'
 exit 1
endif
set DIR = "$1"
set CLASS = "$2"
foreach J ( 'find $DIR -name "*.jar"' )
 printf "."
 set res='jar tvf $J | grep "$CLASS" | sed 's/$/;/''
 set outputsize = 'echo $res|wc -c'
 if ( $outputsize > 1 ) then
 printf "\nMatch found in [$J]\n"
 printf "$res\n" | tr ';' '\n'
 endif
end
printf "\n"

Calling a shell script from another shell script in the same directory
April 3, 2012 Leave a comment
Often when creating a shell script you need to invoke another shell script located in the same directory.
Since your script may be invoked from any place on the file-system, the reference to the other script must be absolute – not relative.
Here is how to do it:
...
SCRIPT_DIR='dirname $0'
. ${SCRIPT_DIR}/other_script.ksh
...
The call to dirname $0 returns the path to the currently running script ($0). The path is relative to the present working directory (PWD).

This paper presents a versatile way for estimating antioxidant activity and anthocyanin content at different ripening stages of sweet cherry by combining image processing and two artificial intelligence (AI) techniques. In comparison with common time-consuming laboratory methods for determining these important attributes, this new way is economical and much faster. The accuracy of artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) models was studied to estimate the outputs. Sensitivity analysis and principal component analysis were used with ANN and ANFIS respectively to specify the most effective attributes on outputs.
Among the designed ANNs, two hidden layer networks with 11-14-9-1 and 11-6-20-1 architectures had the highest correlation coefficients and lowest error values for modeling antioxidant activity (R = 0.93) and anthocyanin content (R = 0.98) respectively. ANFIS models with triangular and two-term Gaussian membership functions gave the best results for antioxidant activity (R = 0.87) and anthocyanin content (R = 0.90) respectively.
Comparison of the models showed that ANN outperformed ANFIS for this case. By considering the advantages of the applied system and the accuracy obtained in somewhat similar studies, it can be concluded that both techniques presented here have good potential to be used as estimators of proposed attributes. © 2013 Society of Chemical Industry

Dynamic instruction set load-in method for Java SoC
By Zhirui Chen and Hongzhou Tan, Sun Yat-sen University Guangzhou China
There are varieties of embedded systems in the world, its a big challenge to optimized the instruction sets of SoCs according to different systems working environments. The idea of dynamic instruction set is a good method to achieve the embedded systems re-configurability. This paper presents a convenient method for a Java processor to work with dynamic instruction set in the form of FPGA or ASIC. The costs of area, power and timing are trivial. Such idea is also reusable for other embedded system solutions.
Dynamic instruction set is very useful in many embedded systems which can be widely used in different areas, and allows engineers developing more efficient instructions or changing the booting up codes. In the Java SoC field, most of the processors both in research or of commercial are designed using fixed instruction set. Only a few choose reconfigurable structures which have to be implemented in FPGA platforms, like the Lavacore. This paper introduces a Javaprocessing chip with real dynamic instruction set inside. The architecture can be implemented not only in FPGAs, but also in ASICs. No matter what purpose an embedded system is designed for, the main idea for dynamic instruction set or say reconfigurable device is to use programmable logic within the SoC.
2 Processor structure
The Java processor used experimentally in this paper is called Java Optimized Processor-JOP. It is a stack-based Java processor with four-stage pipelining. As shown in Figure 1, the four pipeline stages are bytecode fetch, microcode fetch, decode and execute.
Figure 1. Four-stage pipelining
Bytecode is compiled Java instruction in binary form. It is the input for JVM on computers or other Java processors like Jazelle from ARM. Microcode is the native instruction of JOP. All bytecodes in a Java program are translated into series of microcodes first, and then the processor executes the translated local instructionsmicrocodes. This is the basic of the JOP mechanism (Figure 2).
Figure 2. Translation from bytecode to microcode
JOP has different interfaces which allow it to communicate with outside. Considering the point that to design reusable IPs in this experiment, JOP has been modularized and re-constructed using AMBA standard inside the chip. As a good result, the SoC can easily add or remove modules which are conformed to the AMBA standard.
JOP has been tested in different models of FPGAs. Inside the pipelines of JOP, several memory modules are used to implement Java method cache (bytecode RAM), microcode ROM, and stack RAM, which contain local instructions, jump table and variables, etc. Thus RAM-based FPGAs can fully handle the JOP implementation, according to the fact that memory contents can be changed easily by re-programming in FPGAs.
On the other hand, when JOP is implemented in SoC, which it should be, because the performance is much better in SoC then in FPGA for real-time embedded systems, the memory modules are fixed in SoC. ROMs contents are not changeable and the logic cannot be re-programmed to initialize the RAMs.
3 Dynamic load-in method
So far, there are three primary problems when JOP is implemented in a SoC. First, ROM stores all microcodes which are not fully translated the bytecode instructions yet, thus the ROM should be changeable so that microcodes can be extended. Second, when microcodes have been extended, jump table and related variables should be updated as well. Third, unlike FPGAs which can be easily re-programmed, SoC should seek another way to initialize the RAMs.
For the first problem, it can be simply solved by using RAM instead of ROM. As a result, all the memory modules in SoC are RAMs. If there is a convenient way to initialize or re-write all the RAMs in any time, the other two problems are solved already.
Before this JOP chip starting up, no softwares or programs can be executed, because RAMs that supposed to contain the instruction set and other run-time related information are empty. Thus RAMs can only be initialized before system booting up. In that case, a new hardware module should be included in order to load all the microcodes, jump table addresses, variables, etc. into the chip, so that the system can work properly, (shown in Figure 3).
Figure 3. Initializing module in the chip
Figure 3 shows only part of the JOP logic, in order to illustrate the dynamic load-in method more clearly. The main CPU core is an AMBA master module which is tagged as ahb_core. Other controllers are AMBA slaves in this model, such as the NOR-flash controller. The indicated submodules in the main core are RAMs, with jtbl stands for jump-table RAM containing the addresses mapping to the microcode series, ram stands for the stack RAM containing all the constants and variables necessary for the system, and so forth. The pipelining stages are not shown in Figure 3.
The main core should be initialized before it can work properly after power-up, initializing module should be one of the AMBA masters, also the highest priority one, so that the system can automatically load in the contents to the RAMs when the systems power is up.
Figure 4. Initializing procedure
After system is power-on or reset, the initializing module (or named in IM) asks for permission to occupy the data and address buses. As IM has the highest priority, arbiter grants control to IM. Chip-selected signal of each on-chip memory module is controlled by IM, and so are the data and address signals of the memories. Data is loaded from external memory, which in this experiment it is a NOR-flash chip. The address signals in IM will start from zero after each on-chip memory finishes initialization. When all on-chip memories are done, a signal will be raised to release buses controlled by IM, then the main core (lower priority AMBA master) starts to work. Figure 4 shows the initialization procedure.
What IM has to do are, generates chip-selected signals, loads data from external memory, updates addresses related to on-chip RAMs, and sends booting up signals to the main core. The jobs are easy for IM which has a simple logic.
Figure 5. Main IM logics
The main logic of IM is a counter and some controlling signals generating logic. The controlling signals are generated according to the counter. Counting value will be increased by 1 each time an array of data (an array maybe 8-bit, 16-bit or others) is loaded. Though content is changeable in all RAMs, width and size of RAMs are fixed. Thus, controlling signals for RAMs can be generated correctly when the counter counts up to some certain numbers. For example, as shown in Figure 5, the on-chip RAM 1 is a 256×32bit memory. Assuming that the external NOR-flash is 8-bit width, the chip-selected signal of RAM 1 will be disabled and RAM 2 will be enabled for writing data when the counter counts up to 1024.
The address generator changes address relatively. As a RAM starts to be initialized, the address generator counts from zero and upwards. After a RAM is done, generator will clear back the address to zero for a next new RAM.
Not all the on-chip RAMs are in the same width, in order to meet the requirements of variable width of RAMs and storage resource saving, it is better to choose an 8-bit width external nonvolatile memory, such as NOR-flash to store the data. For RAM 1 in Figure 5, it should load four times to form a 32-bit data from external flash. For RAM 3, it should just load two times to form a 16-bit data then cut the high 5 bits out and finally get an 11-bit data.
There is a great advantage for embedded system using this initializing method. One can write a simple booting code or system testing code, then loads into the chip, and all codes can be modified easily when needed. This function will speed up the development and testing procedures of embedded system, as an operation system will be necessary normally when doing these jobs. For this experiment, code segments of clock management, power management, memory control initialization, etc. are implemented as part of the booting code.
For simulation, an Altera Cyclone II FPGA platform is used. The scales of AMBA-based JOP and IM are shown in Figure 6 and Figure 7 separately. According to the summary of logic elements that IM uses, a conclusion can be drawn that this module can be implemented in a SoC with small scale of circuits. The area and power problems caused by IM are trivial.
Figure 6. AMBA-based JOP cost summary
Figure 7. IM cost summary
Timing is not an issue either, as system cannot start to work before all the initial procedures are done. When the initial job is finished, IM will be no longer working and the module can be shut down, the actual working frequency of the chip is not affected by IM.
Also, the time period for initialization is short. The system is booting up already before one can even notice. In this AMBA-based JOP, there are totally 5698×8bits memory which have to be initialized as shown in Table 1. Assumed that the SoC initializing phase works at 50Mhz clock frequency. For reading an 8-bit data from external flash needs 4 clock cycles. The initializing time is 5698×4×20ns, that is 455


corticatization love
Sorry, no definitions found.
Sorry, no etymologies found.
Sorry, no example sentences found.
 - This neologism could be murated from cortication, which means "having a cortex." Such a definition would fit the context of the text in which the word appears in Infinite Jest.
 On the other hand, this word also bears striking similarity to corticalization, which, while the context does not bear out its definition, could still be a significant connection, given DFW's penchant for making such connections.

Writing Applications
Writing an application that can be run as a client within the application-manager is not that much different from writing a stand-alone QML application. It basically boils down to three additional tasks:
 1. If you write a QML application, make the root element of your QML scene an ApplicationManagerWindow (or derive your own custom root item from it).
 2. Provide a valid info.yaml file.
 3. Make the application-manager aware of your application by running appman --recreate-database.
The Root Element
It is recommended to use either an ApplicationManagerWindow or a QtObject as the root of your QML application. This is especially important, if you expect similar behavior in singleand multi-process mode. If a QtObject is used, visible base elements should still be ApplicationManagerWindows. Nevertheless other root elements are supported for convenience, as well. Here are a few things to consider:
 - Only ApplicationManagerWindows support window properties that are shared between the System-UI and the client applications.
 - In multi-porcess mode Window root elements will get a decoration (unless QT_WAYLAND_DISABLE_WINDOWDECORATION is set) and will be invisible by default. QQuick Items will be wrapped inside a Window representing a Wayland client window.
 - In single-process mode Window root elements will appear parallel to instead of inside the System-UI.
The Manifest and Updating the Database
The Manifest Definition documentation has all the information to produce a minimal info.yaml file that should get you going.
Recursively finding and parsing info.yaml files for potentially hundreds of applications can be a very time consuming task and would severely slow down application-manager's startup. Therefore, all manifest files are cached in a binary database. In order to make changes to an info.yaml file known to the application-manager, you have to force a rebuild of this database by calling appman --recreate-database.
Note: Dynamically adding/updating/removing single applications is supported via the ApplicationInstaller interface.
Qmake Integration
To install applications into a system-ui using the Installer Sub-System, the application first needs to be packaged. This can be done using the Packager utility. To better integrate the packaging into your usual developer workflow you can also use the qmake integration provided by the application-manager.
The integration will add an additional package target to the Makefile. By calling make package on the command line or adding it as an additional build step in QtCreator a new application package gets created.
Simple QML Apps
For simple QML only apps, just create a qmake project file which defines an install step for all the needed files. The actual install location doesn't matter in this case, because it will just be used as a temporary path during package creation.
FILES += info.yaml \
 icon.png \
app.files = $$FILES
app.path = /apps/com.example.application
In addition add the following two lines to provide the install location to the packaging step and to load the actual qmake integration.
AM_PACKAGE_DIR = $$app.path
Complex Apps
For more complex apps, where you need to deploy a C++ based QML plugin in addition to your QML content, you need to split your app into multiple folders and project files. One folder for the QML part, another one for the C++ plugin and a SUBDIRS project to glue them together.
The packaging integration will be done in the SUBDIRS project and expects that the other project files provide install targets to a shared install location. E.g the QML part installs it's files to '/apps/com.example.application', while the C++ plugin will install to '/apps/com.example.application/imports/com/example/application'.
In the SUBDIRS project you need to define the AM_MANIFEST variable and set it to the location of your info.yaml file as well as define the shared install location as AM_PACKAGE_DIR:
AM_MANIFEST = $$PWD/app/info.yaml
AM_PACKAGE_DIR = /apps/com.example.application
Packaging multiple apps
If your repository provides multiple apps, like the Qt Auto Extra Apps Repository, you can use the am-package qmake feature to provide a repository wide package step.
Just add a ".qmake.conf" file with the following content to your repository, which gets automatically loaded by qmake:
CONFIG += am-package


handler.
Session timeout
Sessions will be automatically timed out if they are not accessed for a time greater than the timeout period. When a session is timed out, it is removed from the store.
Sessions are automatically marked as accessed when a request arrives and the session is looked up and and when the response is complete and the session is stored back in the store.
You can also use setAccessed to manually mark a session as accessed.
The session timeout can be configured when creating the session handler. Default timeout is 30 minutes.
Authentication / authorisation
Vert.x comes with some out-of-the-box handlers for handling both authentication and authorisation.
Creating an auth handler
To create an auth handler you need an instance of AuthProvider. Auth provider is used for authentication and authorisation of users. Vert.x provides several auth provider instances out of the box in the vertx-auth project. For full information on auth providers and how to use and configure them please consult the auth documentation.
Here's a simple example of creating a basic auth handler given an auth provider.
router.route().handler(CookieHandler.create());
router.route().handler(SessionHandler.create(LocalSessionStore.create(vertx)));
AuthHandler basicAuthHandler = BasicAuthHandler.create(authProvider);
Handling auth in your application
Let's say you want all requests to paths that start with /private/ to be subject to auth. To do that you make sure your auth handler is before your application handlers on those paths:
router.route().handler(CookieHandler.create());
router.route().handler(SessionHandler.create(LocalSessionStore.create(vertx)));
router.route().handler(UserSessionHandler.create(authProvider));
AuthHandler basicAuthHandler = BasicAuthHandler.create(authProvider);
// All requests to paths starting with '/private/' will be protected
router.route("/private/*").handler(basicAuthHandler);
router.route("/someotherpath").handler(routingContext -> {
 // This will be public access - no login required
});
router.route("/private/somepath").handler(routingContext -> {
 // This will require a login
 // This will have the value true
 boolean isAuthenticated = routingContext.user() != null;
});
If the auth handler has successfully authenticated and authorised the user it will inject a User object into the RoutingContext so it's available in your handlers with: user.
If you want your User object to be stored in the session so it's available between requests so you don't have to authenticate on each request, then you should make sure you have a session handler and a user session handler on matching routes before the auth handler.
Once you have your user object you can also programmatically use the methods on it to authorise the user.
If you want to cause the user to be logged out you can call clearUser on the routing context.
HTTP Basic Authentication
HTTP Basic Authentication is a simple means of authentication that can be appropriate for simple applications.
With basic auth, credentials are sent unencrypted across the wire in HTTP headers so it's essential that you serve your application using HTTPS not HTTP.
With basic auth, if a user requests a resource that requires authorisation, the basic auth handler will send back a 401 response with the header WWW-Authenticate set. This prompts the browser to show a log-in dialogue and prompt the user to enter their username and password.
The request is made to the resource again, this time with the Authorization header set, containing the username and password encoded in Base64.
When the basic auth handler receives this information, it calls the configured AuthProvider with the username and password to authenticate the user. If the authentication is successful the handler attempts to authorise the user. If that is successful then the routing of the request is allowed to continue to the application handlers, otherwise a 403 response is returned to signify that access is denied.
The auth handler can be set-up with a set of authorities that are required for access to the resources to be granted.
Redirect auth handler
With redirect auth handling the user is redirected to towards a login page in the case they are trying to access a protected resource and they are not logged in.
The user then fills in the login form and submits it. This is handled by the server which authenticates the user and, if authenticated redirects the user back to the original resource.
To use redirect auth you configure an instance of RedirectAuthHandler instead of a basic auth handler.
You will also need to setup handlers to serve your actual login page, and a handler to handle the actual login itself. To handle the login we provide a prebuilt handler FormLoginHandler for the purpose.
Here's an example of a simple app, using a redirect auth handler on the default redirect url /loginpage.
router.route().handler(CookieHandler.create());
router.route().handler(SessionHandler.create(LocalSessionStore.create(vertx)));
router.route().handler(UserSessionHandler.create(authProvider));
AuthHandler redirectAuthHandler = RedirectAuthHandler.create(authProvider);
// All requests to paths starting with '/private/' will be protected
router.route("/private/*").handler(redirectAuthHandler);
// Handle the actual login
router.route("/login").handler(FormLoginHandler.create(authProvider));
// Set a static server to serve static resources, e.g. the login page
router.route().handler(StaticHandler.create());
router.route("/someotherpath").handler(routingContext -> {
 // This will be public access - no login required
});
router.route("/private/somepath").handler(routingContext -> {
 // This will require a login
 // This will have the value true
 boolean isAuthenticated = routingContext.user() != null;
});
JWT authorisation
With JWT authorisation resources can be protected by means of permissions and users without enough rights are denied access.
To use this handler there are 2 steps involved:
 - Setup an handler to issue tokens (or rely on a 3rd party)
 - Setup the handler to filter the requests
Please note that these 2 handlers should be only available on HTTPS, not doing so allows sniffing the tokens in transit which leads to session hijacking attacks.
Here's an example on how to issue tokens:
Router router = Router.router(vertx);
JsonObject authConfig = new JsonObject().put("keyStore", new JsonObject()
 .put("type", "jceks")
 .put("path", "keystore.jceks")
 .put("password", "secret"));
JWTAuth authProvider = JWTAuth.create(vertx, authConfig);
router.route("/login").handler(ctx -> {
 // this is an example, authentication should be done with another provider...
 if ("paulo".equals(ctx.request().getParam("username")) && "secret".equals(ctx.request().getParam("password"))) {
 ctx.response().end(authProvider.generateToken(new JsonObject().put("sub", "paulo"), new JWTOptions()));
 } else {
 ctx.fail(401);
 }
});
Now that your client has a token all it is required is that for all consequent request the HTTP header Authorization is filled with: Bearer <token> e.g.:
Router router = Router.router(vertx);
JsonObject authConfig = new JsonObject().put("keyStore", new JsonObject()
 .put("type", "jceks")
 .put("path", "keystore.jceks")
 .put("password", "secret"));
JWTAuth authProvider = JWTAuth.create(vertx, au

FAFSA Completion Increases 8.5% for Class of 2017
ICAN's FAFSA Ready Iowa Initiative Making Great Strides Toward 70% Goal
HIAWATHA, IOWA (July 17, 2017) — The Iowa College Access Network (ICAN) is pleased to announce that FAFSA completion rates through June 30 are up for Iowa high school seniors by 8.5 percent over the previous year.
Over the past year changes to the financial aid timeline and process have provided students the opportunity to access financial aid earlier and with greater ease. FAFSA, or the Free Application for Federal Student Aid, is the federal form required to access both federal and state financial aid, including grants and federal student loans. By completing the FAFSA, Iowa students can unlock millions of dollars in aid, making the successful completion of education and training beyond high school a reality.
Data shows that students have an 85 percent chance of being awarded financial aid by simply completing the form. ICAN's work, in partnership with both the high school counseling and higher education communities of Iowa, has made great strides in bringing awareness of the importance of FAFSA completion to high school seniors. Through its FAFSA Ready Iowa FAFSA assistance events, community grant initiatives, and school-based programming, ICAN and its partners are making an impact on FAFSA completion in Iowa, and in helping students attain their future goals.
"Awareness and outreach programs are an important aspect of FAFSA completion, but the real impact comes from having skilled and knowledgeable professionals to meet one-on-one with families and help them maximize their unique situations. That's where ICAN really moves the needle on FAFSA completion." Stated Rob Miller, President of the Iowa College Access Network (ICAN.)
In an effort to empower students with the knowledge and assistance to navigate the financial aid process, ICAN launched the FAFSA Ready Iowa Initiative in Fall 2016, amplifying the successful Iowa College Goal Sunday FAFSA assistance program with additional outreach and support to both students and school counselors. FAFSA Ready Iowa is part of a wider effort by ICAN to reach every middle- and high school and every student in Iowa to better prepare students for college and the workforce. According to the Georgetown Center on Education and the Workforce, more than 60 percent of Iowa jobs will require a college education by 2020.
"Education and training beyond high school is necessity for long-term success in the ever-changing job market," explained Miller. "This initiative enables Iowa students to gain access to the financial aid that helps cover the expenses of obtaining the education and training needed to be competitive in today's workforce."
As part of the FAFSA Ready Iowa initiative and in addition to the statewide events, ICAN has partnered with local community foundations throughout the state on county and school-based FAFSA initiatives to bring systemic change to specific districts and counties including Benton, Black Hawk, Emmet, Humboldt, Kossuth, Linn, Muscatine, Scott, and Tama Counties.
ICAN, a nonprofit organization providing career and college readiness planning to students and parents in Iowa, has been educating and empowering Iowa's future workforce since 1998.

In this study, molecular properties of wheat starch from three different types of breads were analyzed using asymmetric flow field-flow (AF4) connected to multi-angle light scattering (MALS) and differential refractive index (dRI) detectors. This analysis allowed the determination of molecular properties, i.e. molar mass (M), root-mean-square radius (rrms), apparent density (ρapp) and conformation. Complementary analyses, such as resistant starch and amylose content, were also performed. The results show that wheat starch extracted from breads can have different properties reflected in changes in M, rrms and ρapp. In addition, the results suggest that some of the changes in molecular properties may be related to the presence of resistant starch.

Understanding the Concept
Imagine you have a column of numbers, and you want them all to be the same length for clarity and consistency. This is where RPAD comes into play. It ensures that the values are right-padded with spaces or a specified character until they meet the desired length. This process is particularly useful in database management and when working with fixed-width data formats.

Practical Applications
RPAD is frequently employed in SQL (Structured Query Language) to format output and enhance readability. For example, when retrieving data from a database, you might use RPAD to ensure that values in a column are uniformly presented. This not only facilitates easier analysis but also improves the visual appeal of the data.

How to Scan 50 Miles of Historical Documents Into an Online Archive
By Jordan Kushins on at
Tracking the lightning-quick development of modern cities is easy with Google Street View, but a big new project aims to provide context for the past 1,000 years of urban evolution in Venice, Italy. The Venice Time Machine will digitalise and catalogue a staggering amount of historical documents (a combined 50 miles worth of shelves!) before turning the data into an internet archive and adaptable 3D model.
Timing-wise, it certainly lines up with the zeitgeisty rush of cultural institutions, from the Met to the New York Public Library, putting their collections online and free for the public to browse. In this case, pulling together all the documents into a cohesive whole will be a pretty epic challenge, and one that's been centuries in the making.
The archives were located in different spots around the city until 1815, when they were moved to the Frari's convent in the middle of town. Now, the stacks and stacks (and stacks and stacks) contain a millennium's worth of all kinds of handwritten texts: maps, correspondences, tax statements, architectural plans, travel guides, and peace treaties, even birth and death registries and wills.
The multi-step process, helmed by the École Polytechnique Fédérale de Lausanne, the University Ca' Foscari, and the Lombard Odier Foundation, will involve significant input from both computers and people, using technology that is currently being tested and perfected. First, everything will be scanned by a semi-automatic robotic scanning unit into high resolution images, or—and this sounds incredible—a technique using "X-ray synchrotron radiation produced by a particle accelerator" will allow scanning without even turning a page.
How To Scan 50 Miles of Historical Documents Into an Online Archive
Those images will be transcribed with the help a text processor powered by the kind of algorithms used for protein structure analysis; these will detect strings of words that could be sentences.
Finally, a massive taxonomy of key phrases, people, and places will build out this interconnected, entirely searchable database. Eventually, the team believes they'll be able to create a morphing 3D model of Venice through the years, based on the gathered and synthesised info.
It will be fascinating to watch this process unfold, and its success could have major implications for putting more rare, print-only artefacts into the global mix. [Gizmag]

Young woman in a bra, lady's briefs and socks.
Underpants (also called undies for short, especially among children and young adults) is a general term for items of underwear that cover the body from the waist to, at least, the top of the thighs. They are worn directly on the skin and under other items of clothing. Their purpose is to provide modesty, comfort and hygiene.
The word "underpants" is slightly more British than American English, and somewhat archaic as it has been shortened to "pants" in British English. "Underpants" tends to sound childish and evokes practical cotton basic styles only; it might also be used in medical or technical contexts, or as a formal word to refer to children's underwear.
Types of underpants include:
Up to the early 19th century, girls and women generally did not wear any kind of underpants.
Since the Middle Ages, men began to wear a loose undergarment called brouche or braies. These were eventually replaced by simple cotton, silk or linen drawers, which were usually knee-length trousers with a button flap in the front. Such underwear was usually worn under trousers, whereas under tunic-style garments it was usually preferred to go without. The Scottish kilt is a good example of this tradition.
Women did not wear any such garment, as it was considered specifically male. It took until the mid-19th century when women began to wear drawers too.
Schoolyard rhyme[edit]
The schoolyard rhyme "I see London, I see France, I see someone's underpants" is used by children to make fun of a child whose underpants are acidentally showing (see also panchira).

Christian Authors Network and CBA Partner
for Literacy Mission Outreach at ICRS 2015
O'Fallon, IL— The Christian Authors Network and the Christian Booksellers Association will co-host two literacy events for 500 inner city, at risk children (ages preschool through high school) of the Orlando Children's Church prior to ICRS 2015 in Orlando, Florida. The events include author-child literacy activities and distribution of books, magazines, and reading related items.
OCC Children Meet CAN Authors
On Saturday, June 27th, Christian Authors Network children's authors will visit the Orlando Children's Church. Five hundred children will participate in literacy activities with a Christian focus. Eddie Jones (The Caden Chronicles), Carol McAdams Moore (Dare U 2 Open This Book and Just Sayin'), and Karen Whiting (Nature Girl and The One Year Devotions for Active Boys) will talk to large groups about writing and exploring God's Word through books. Katrina Cassel (Promises for God's Princesses), Diane Stortz (Words to Dream On), and Rebecca White (Nature Girl) with work with break out groups of children to explore crafts, songs, devotions and rhymes in books. No child will leave the event empty handed.
550 Literacy Bags for Children
Each of the 500 children at the Orlando Children's Church event will receive a bag containing a book by a Christian author, Christian magazines for children, and various literacy-related items. Fifty children from the church signing at the ICRS Worship Him event will also receive a bag.
OCC Children to Sing at Worship Him
Prior to singing at Worship Him on Sunday evening, children from the Orlando Church will enjoy a hot dog supper (courtesy of the CBA), hear devotions by children's authors Crystal Bowman and Dandi Daley Mackall, and receive a unique literacy bag from CAN.
The Orlando Children's Church ministers to children by sharing a clear gospel message and by feeding, clothing and teaching them life lessons and principles. Reaching children starting at the age of 4 up to 12th grade, the Orlando Children's church has seen tens of thousands of children move through their ranks, with thousands coming to Christ over the years.
Peter O'Driscoll, Orlando Children's Church founder, comments, "Children are the living messages that we send to a time and to a place that often we will never see. Let's send there as Christians with a heart full of love and Spirit of Christ."
"What's different about Christian authors? We're in literal ministry. We, at the Christian Authors Network, are bonded together in marketing. But our first priority is to minister to those the Lord brings into our sphere of influence. I'm honored to be part of something so much bigger than a marketing group."—Angela Breidenbach, CAN president
The Christian Authors Network, a marketing cooperative, was founded in 2005 and currently serves retailers and librarians nationally with professional, traditionally published experts through online, in person, and print resources.

2 Surgical Asepsis in the OR Principles of Sterile Technique Becky Ellis, MN RN Nurse Educator N230
3 Course Information You are about to begin learning about Surgical Asepsis. Part of this module is devoted to the theory of asepsis as it is used in the operating room. The second half of this module is devoted to teaching you the skills needed for your OR experience, particularly those of scrubbing, gowning, and gloving.
4 Purpose The purpose of this module is to acquaint the nursing student with surgical asepsis, surgical scrubbing and the gowning and gloving techniques that will be used during their OR rotation. This module is meant to be on overview and a module to be studied at the students convenience. The student must successfully complete this module prior their OR check off in the skills lab and prior to their OR rotation at their health care facility.
5 Learning Objectives After completing this self study course the student will be able to: Describe the fundamental principles of safe conduct and the basic rules for aseptic technique in the operating room. Demonstrate the correct technique of the surgical scrub and the correct gowning and gloving technique.
6 Pretest Instructions The next 5 questions compose a pretest to gauge your knowledge and ability prior to starting this module. Select the best answer, then double click with your mouse. Now here we go

10 2. Cross-contamination is defined as: A. Producing or capable of producing disease. B. Transmission of microorganisms from patient to patient and from inanimate objects to patients. C. Severe toxic state resulting from infection with pyogenic organisms.
11
12 Correct!! Cross-contamination is the Transmission of microorganisms
13 3. Which task or function during a surgical procedure is designed as being within the scope of the practice of the scrub nurse? A. Closing the surgical wound B. Setting up the sterile field C. Administering blood products
14
15 Right Again!! The Scrub nurse prepares the sterile field
16 4. For which member of the surgical team is a surgical scrub unnecessary? A. Anesthetist/anesthesiologist B. Surgical technologist C. Scrub nurse
17
18 WOW! You are doing great. Another Right answer! Proceed onto the next question, please
19 5. Which is the best technique for you to use when rinsing your hands and forearms after a surgical scrub? A. Rinsing is not performed after a surgical scrub because it will reduce the antimicrobial activity of the cleansing solution. B. Rinsing should start at the elbow with the water running down back down to the hand. C. Rinsing should start with the hand positioned such that water runs off the elbow rather than down to the hands.
20
21 Correct Answer!! You have completed your pretest so its time to continue on with the module.
22 Answers to Pretest 1. Correct answer is (a.) Absence of microorganisms. 2. Correct answer is (b.) Transmission of microorganisms from patient to patient and from inanimate objects to patients. 3. Correct answer is (b.) Setting up the sterile field. 4. Correct answer is (a.) Anesthetist/anesthesiologist. 5. Correct answer is (c.) Rinsing should start with the hand positioned such that water runs off the elbow rather than down to the hands.
23 1. Only sterile items are used within the sterile field 2. Sterile persons are gowned and gloved 3. Tables are sterile only at table level 4. Sterile persons touch only sterile items or areas 5. Unsterile persons avoid reaching over the sterile field 6. The edges of anything that encloses sterile contents are considered unsterile
24 7. The sterile field is created as close as possible to the time of use 8. Sterile areas are continuously kept in view 9. Sterile persons keep well within the sterile area 10. Sterile persons keep contact with sterile areas to a minimum 11. Unsterile persons avoid sterile areas 12. Destruction of the integrity of microbial barriers results in contamination
25 1. Only Sterile Items Are Used Within A Sterile Field Discard any contaminated items: If a sterile package is found in a contaminated area. If uncertain about the actual timing or operation of the sterilizer. If an unsterile person comes into close contact with a sterile table. If a sterile table or unwrapped sterile items are not under constant supervision.
26 Only Sterile Items Are Used Within the Sterile Field (Continued) Discard any contaminated items: If the integrity of the packaging material is not intact. If a sterile package wrapped in a material other than plastic or another moisture- resistant barrier becomes damp or wet. If a sterile package wrapped in a pervious woven material drops on the floor or other areas of questionable cleanliness.
27 2. Sterile Persons are Gowned and Gloved Observed gowning practices. Self-gowning and gloving should be done from a separate sterile surface to avoid dripping water onto sterile supplies or a sterile table. The stockinette cuffs of the gown are enclosed beneath sterile gloves. The stockinette is absorbent and retains moisture, and doesnt provide a microbial border. Sterile persons keep their hands in sight at all times and at or above waist level or the level of the sterile field.
28 Sterile Persons are Gowned and Gloved (Continued) Observed gowning practices (cont). Hands are kept away from the face, and the elbows are kept close to the sides. The back of the gown is considered contaminated. The gown is considered sterile only to the highest level of the sterile tables.
29 3. Tables Are Sterile Only At The Table Level Sterile table. Only the top of a sterile, draped table is considered sterile. The edges and sides of the drape extending below table level are considered unsterile. Anything falling or extending over the table edge, such as a piece of suture, is unsterile. When unfolding a sterile drape, the part that drops below the table surface is not brought back up to table level.
30 4. Sterile Persons Tough Only Sterile Items or Areas Sterile team members maintain contact with the sterile field by means of sterile gowns and gloves. The unsterile circulator does not directly contact the sterile field. Supplies are brought to sterile team members by the circulator, who opens the wrappers on sterile packages.
31 5. Unsterile Persons Avoid Reaching Over the Sterile Field The unsterile circulator never reaches over a sterile field to transfer sterile items. The circulator holds only the lip of the bottle over the basin when pouring solution into a sterile basin in order to avoid reaching over the sterile area. The scrub person sets basins or glasses to be filled at the edge of the sterile table.
32 6. Edges of Anything That Encloses Sterile Contents Are Considered Unsterile The inside of a wrapper is considered sterile to within 1 inch of the edges. The circulator opens top flap away from self. Then turns the sides under. The ends of the flaps are secured in the hand so they do not dangle loosely. The last flap is pulled toward the person opening the package, thereby exposing the package contents away from the unsterile hand.
33 Edges of Anything That Encloses Sterile Contents Are Considered Unsterile (Cont) Sterile persons lift contents from packages by reaching down and lifting them straight up, holding their elbows high. The flaps on peel-open packages should be pulled back, not torn, to expose the sterile contents. The contents should not be permitted to slide over the edges.
34 Edges of Anything That Encloses Sterile Contents Are Considered Unsterile (Cont) After a sterile bottle is opened, the contents are either used or discarded. The cap cannot be replaced without contaminating the pouring edges.
35 7. The Sterile Field Is Created As Close As Possible to the Time of Use Sterile tables are set up just prior to the surgical procedure. It is virtually impossible to uncover a table of sterile contents without contamination. Covering sterile tables for later use is not recommended. A covered table is not under observation at all times.
36 8. Sterile Areas Are Continuously Kept in View Sterile persons face sterile areas. Someone must remain in the room to maintain vigilance when sterile packs are opened in a room or a sterile field is set up. Sterility cannot by ensured without direct observation. An unguarded sterile field should be considered contaminated.
37 9. Sterile Persons Keep Well Within the Sterile Area Sterile persons stand back at a safe distance from operating bed when draping the patient. Sterile persons pass each other back to back at a 360-degree turn. Sterile persons turn their backs to an unsterile person or area when passing. Sterile persons face a sterile area to pass it.
38 Sterile Persons Keep Well Within the Sterile Area (Cont) Sterile persons ask an unsterile individual to step aside rather than risk contamination. Sterile persons stay within the sterile field. They do not walk around or go outside the room. Movement within and around a sterile area is kept to a minimum to avoid contamination of sterile items or persons.
39 10. Sterile Persons Keep Contact With Sterile Areas to a Minimum Sterile persons do not lean on sterile tables or

Extrinsic Fabry-Perot Interferometer System Using Wavelength Modulated Source
Meller, Scott A.
MetadataShow full item record
Interferometric optical fiber sensors have proved many orders of magnitude more sensitive than their electrical counterparts, but they suffer from limitations in signal demodulation caused by phase ambiguity and complex fringe counting when the output phase difference exceeds one fringe period. Various signal demodulation methods have been developed to overcome some of the these drawbacks with limited success. This thesis proposes a new measurement system for the extrinsic Fabry-Perot interferometer (EFPI) sensor. Using a wavelength modulated source and a novel extended-gap EFPI, some of the limitations of interferometric signal demodulation are overcome. By scanning the output wavelength of a multilongitudinal mode laser diode through current modulation, the EFPI sensor signal is scanned through multiple fringes. Gap movement is then unambiguously determined by monitoring the phase of the multiple fringe pattern.

Myself Belts - Belts Kids Can Fasten Themselves Print E-mail
myselfbeltsmyself-belts Most toddlers "do it myself!" ideas send parents running for the hills - or at least to the nearest hardware store to load up on enough childproof gear to cover any big ideas your little tot might have. But there are some things we wish our kids could do all by themselves - undress quickly enough to use the bathroom without any assistance, for instance?
Look no further than Myself Belts, the greatest pants-keeper-upper since, well, the normal belt. Without the hassle of buckles and loops, these ingenious belts attach themselves to the child's belt loop, and let kids do the rest. Myself Belts close with a secure velcro front that allows for easy opening and closing, so that Mom no longer becomes the bathroom gate keeper.
myselfbelts-designs Give your child a sense of independence, especially during the potty-training stage, when learning to "do it yourself" is crucial. And for a little added fun, Myself Belts don't just come in brown leather but also in ABCs, sailboats, fire trucks, and more adorable patterns.
Next time your child asks to do something independently, make sure his idea involves a Myself Belt, and not a hose, soap, and the dog!

Why do you live with your tia/aunt?: Making Sense of Cultural and Family Identities as a Latinx Foster Youth
In 2017, more than 690,000 children spent time in foster care, and on any given day in the US, more than 443,000 children are in foster care. One-third of all foster youth are children of color, with 93,507 children identifying as Hispanic/Latinx. People identifying as Latinx are the fastest growing group in the child welfare system. Michael will be interviewing Latinx foster youth from across California, focusing on the cultural and family identities of each participant. Familia/family, culture, and ethnic identity are cornerstones of the Latinx community, so how do Latinx foster youth navigate these spaces? The projects goal is disruption: disrupting extractive research practices, disrupting Black/white binaries, disrupting foster youth research conducted by non-foster youth researchers, and emphasizing Latinx foster youth voices.

The arches were built in 1913 to celebrate the 100th anniversary of the village's founding and are listed on the National Register of Historic Places.
A community founded by Thomas Lake Harris in 1867 is also considered a historic site.
According to a history written by Ed Kurtz Sr., the Harris community members were considered Socialists. In 1875, Harris left the area to found a new community in California and was followed there by many of his members. The Harris house is now privately owned.
Brocton operates its own water, sewer and power plants, and the community is also known as the birthplace of railroad sleeping car inventor George Pullman and Marmaduke cartoonist Brad Anderson.
The state Department of Corrections' Lakeview Shock Incarceration Correction Facility is located within the village's borders.

Motion<T> and Motion<T, TDerivative>
Motion<T> and Motion<T, TDerivative> are fundamental types used throughout DME Component Libraries. This topic will provide an overview of these types and how they work.
Motion Types
Motion<T> holds a coordinate value and zero or more derivatives. For example, a Motion<Cartesian> is typically used to represent translational motion and holds a Cartesian position vector plus an optional Cartesian velocity vector, Cartesian acceleration vector, etc.
Motion<T, TDerivative> also holds a value and zero or more derivatives, but in this case the coordinate value and the derivatives are represented using different types. A common example of this is a Motion<UnitQuaternion, Cartesian>, which is typically used to represent rotational motion and holds a UnitQuaternion rotation plus an optional Cartesian rotational velocity vector, Cartesian rotational acceleration vector, etc.
You can obtain the coordinate value of a Motion<T> or Motion<T, TDerivative> instance by accessing the Value property. For example:
C#
Motion<Cartesian> translationalMotion = AnyOldFunction1();
Cartesian position = translationalMotion.Value;
Motion<UnitQuaternion, Cartesian> rotationalMotion = AnyOldFunction2();
UnitQuaternion rotation = rotationalMotion.Value;
Similarly, you can access the first and second derivatives:
C#
Motion<Cartesian> translationalMotion = AnyOldFunction1();
Cartesian velocity = translationalMotion.FirstDerivative;
Cartesian acceleration = translationalMotion.SecondDerivative;
Motion<UnitQuaternion, Cartesian> rotationalMotion = AnyOldFunction2();
Cartesian rotationalVelocity = rotationalMotion.FirstDerivative;
Cartesian rotationalAcceleration = rotationalMotion.SecondDerivative;
You can access higher-order derivatives by using Further derivatives can be accessed using the indexer (ItemInt32).
C#
Motion<Cartesian> translationalMotion = AnyOldFunction1();
Cartesian jerk = translationalMotion[3];
Motion<UnitQuaternion, Cartesian> rotationalMotion = AnyOldFunction2();
Cartesian rotationalJerk = rotationalMotion[3];
If an instance does not have a first, second, or higher-order derivative, it will throw an ArgumentOutOfRangeException when you attempt to access that derivative. You can determine the highest-order derivative available from a particular motion instance by accessing the Order property.
Methods that return Motion<T> or Motion<T, TDerivative> often accept an order parameter. This parameter indicates the highest derivative that the caller of the function would like returned. The order parameter is primarily an optimization which allows the method to avoid wasting time computing higher derivatives if they will not be utilized. An order of 0 indicates that you require only the coordinate value and not any of its derivatives. An order of 1 requests the first derivative in addition to the coordinate value. An order of 2 requests the coordinate value, its first derivative, and its second derivative. An arbitrarily high order can be requested, though not all methods will be able to fulfill all requests.
If a method is not able to provide a requested derivative, an exception or other error will not occur. Instead, the method will simply provide the highest derivative that it is able to provide. It is up to the caller of the method to verify that a required derivative is present in the return value.

Tiles on a Patio

Stage: 2 Challenge Level: Challenge Level:1
Chetan sent in this solution.
The total area of each one of the square shaped patio (3 X 3, 4 X 4, 5 X 5) is 9, 16 and 25 respectively.
Hence, with the available size of 1 X 1, 2 X 2, 3 X 3 and 4 X 4, we just need to find the tile values that total the area of the square.
example: for 4 X 4 = 16. Hence, the sum of the tiles areas should add up to 16.
no. of 4 X 4 = 1 (area 16)
no. of 1 X 1 = 16 (area 16)
no. of 2 X 2 = 4 (area 16)
no. of 3 X 3 = 1; 1 X 1 = 7 (area 16)
Hence, with respect to the total area of the square we will need to calculate the factors that sum up to the total number.
However, Paul from Brentside High School said:
So with a 5x5 square you could assume that: 1 tile of 3x3 = 9 and 4 tiles of 2x2 =16.
As 9+16 = 25 therefore you could use 5 tiles.
But in fact you can't as there is no configuration that will fit (without cutting the tiles which is not allowed).
So to say that we just need to find tile values that total the area of the square is not correct.
You are absolutely right, Paul. Paul goes on to wonder whether there is a purely numerical solution to the problem. I am not sure that there is, as you would have to take into account the spatial aspect too. What do you think?


How many valence electrons does scandium have?
Quick Answer
Scandium, element 21 on the periodic table, has 2 valence electrons. Valence electrons are the electrons that occupy the highest energy orbital of an atom. They are the electrons in an atom that participate in chemical reactions.
Continue Reading
Full Answer
Scandium's electron configuration is [Ar] 3d1 4s2. The 4s orbital is the one that houses its valence electrons. Since valence electrons are the primary electrons involved in chemical reactions, they are a key factor in determining an element's chemical properties. Elements in the same column, or group, of the periodic table have the same number of valence electrons, so they frequently have similar chemical and physical properties; scandium is a group 3 element, and it shares many physical properties with other group 3 elements, such as lutetium and yttrium. For example, these elements have very similar melting points.
