If you're making a concrete curb, patio, sidewalk, or driveway, use one of these edgers to improve the appearance of the finished slab and reduce risk of chipping on the edges.
These tools have a flat face with a handle on the back, and one edge of the face is curved down away from the handle. The curved edge is inserted between the wet concrete and the form being used to shape it, and then the tool is pushed along all sides of the slab to separate the media from the form and to smooth and round the edges of the wet concrete.
For Close Reach
These handheld edgers can be operated with one hand. They are used while kneeling next to the work surface and are well suited for edging small areas.
With Plastic Handle
With Wood Handle
For Extended Reach
Also known as walking edgers, these edgers have a long handle and can be pushed along the edge of a slab of wet concrete while walking. They are a good choice for edging large areas.

This week Anditi's principal software architect and LiDAR dataset diagnostics guru Patrick Poissant and Head of Business Operations and quality queen Catherine Pepper continue the 4 part blog series on the common pitfalls to avoid in the capture of LiDAR with a discussion on things to consider when planning your capture program. See Part 1: Planning for success for ways to plan your project to ensure you're setting yourself up to succeed, and Part 2: The Role of the IMU for what factors you should consider to ensure the data reporting from the IMU is as accurate as possible.
This post focuses on another key element of data collection – swathes and how to get them working for you, including best practices for flight paths, swathe overlap and point density for better results in the processing of your LiDAR data.
What is a swathe?
A swathe is the spatial arrangement of returns generated by a pulse from a remote sensing scanner. Often also referred to as the 'flight line' or 'strip', the swathe is the set of points collected by a single scanner, overlapped with other swathes to generate a dataset.
LiDAR collection has traditionally been thought of as costly, and therefore capturing as little data as possible has been one of the methods used to reduce flight time, and in turn, decrease cost. However, our experience has shown that capturing the bare minimum often leads to holes in the data, which creates a dataset that was cheap to capture but is difficult to classify, and of not much use for 3D analytics and providing accurate spatial insights.
The best way to manage cost and quality of the data captured is to effectively plan your flight path. This involves a few steps that we've outlined below.
1. Plan a flight path to ensure you will get 100% coverage of the area you're interested in
First things first – identify the area you're interested in! It's important to allow a buffer for coverage of the exact area you want, as wind and weather conditions can often put your flight plan off slightly. Covering a little extra gives you margin for error that won't result in a compromise on a complete data set. We recommend a buffer of a few hundred metres around your area of interest.
2. Allow for overlap
Our experience shows that flight paths that allow for approximately 30-40% overlap of the swathes are likely to give you the best results as that helps prevent gaps in the data. Using this amount of overlap gives the data processing platform you're using the best chance of recognizing patterns in the data, and using them to align the swathes. However, increased point density does mean increased processing time and demand on the processing system, something Anditi has overcome with patented technology and smart distributed computing. In fact, in some cases an increased point density may result in reduced data processing costs because features will become easier to detect and therefore require less pre-processing and computation.
3. Plan for the appropriate point density
As we described in the first post in our series on LiDAR point clouds, planning your project based on what you want to do with the data is key. This is particularly the case when deciding on the appropriate point density for your project. The point density you need is determined by the size of the near ground features that you are trying to detect. The spacing of LiDAR points needs to be at most half the size of the feature you want to detect. For example, in the case of malleefowl mound detection, the ground features we are trying to detect have a radius of approximately 1 to 3 metres. That means you need a point density of at least 2 points per square metre to be able to detect the shape of the mound with any confidence. Confidence in detection of mounds increases with increasing point density, so we generally recommend point densities in the order of 6 to 10 points per m2. You can read about our malleefowl mound detection work in the Great victoria desert Case study.
The point density is a function of many different decisions in the LiDAR collection process including:
- Aircraft Elevation
- Scanner Frequency
- Scan pattern
- Overlap strategy
Flying at a higher elevation results in cheaper acquisition of data because the width of the swathe will be larger and the area can be covered more quickly. However, most scanners experience a slight reduction in precision associated with the greater distances between the scanner and the ground. Optimising the combination of these factors requires careful planning and should include discussions between the data collection team and the team who will be doing the analytics to ensure the data captured is fit for its intended use.
Using high density LiDAR data, we were able to identify 676 high probability mound candidates within the 600 km2 area.
4. Post processing is key
Technology has come a long way, and understanding the scanning frequency, or point density, you need for your job is important. Traditionally satellites have collected data at 50cm resolution or more. New technology means data can be collected by airborne lasers in excess of 100 points per m2. Of course such a high density of points can mean extremely accurate DTMs, 3D models and analytics, but it also means huge datasets that require smart handling so as not to overload your system. Again this is where we pride ourselves on having some of the best high performance computing technology on the market.
This is why it is important to know what you need for your project, the less density you need in data capture, the less resolution you will have, but the cheaper it will be. 30cm pixels are fine for identifying broad features such as new developments and bodies of water, but higher densities are helpful when you're using automated classification to identify features like roof planes and powerlines.
The beauty of well aligned swathes
If you manage to properly plan your flight path, create a nice overlap in your swathes and have access to a nice spatial data processing platform, it is possible to align the data from each swathe so accurately that the resulting union acts as a single, accurate point cloud, with double the point density of each individual swathe.
What to do if your swathes are misaligned
Over the years we've seen examples of datasets where swathes are misaligned, swathe overlap is insufficient, or the dataset is of a quality that makes it difficult to achieve the kind of outcomes that were hoped for. If you're in that boat, we have developed a series of tools and processes to review the data, identify any problems and determine if and how the dataset can be fixed.

How to increase the space between the bars in a bar plot in ggplot2?
You can always play with the width parameter, as shown below:
df <- data.frame(x=factor(LETTERS[1:4]), y=sample(1:100, 4))
library(ggplot2)
ggplot(data=df, aes(x=x, y=y, width=.5)) +
 geom_bar(stat="identity", position="identity") +
 opts(title="width = .5") + labs(x="", y="") +
 theme_bw()
Compare with the following other settings for width:
alt text
So far, so good. Now, suppose we have two factors. In case you would like to play with evenly spaced juxtaposed bars (like when using space together with beside=TRUE in barplot() ), it's not so easy using geom_bar(position="dodge"): you can change bar width, but not add space in between adjacent bars (and I didn't find a convenient solution on Google). I ended up with something like that:
df <- data.frame(g=gl(2, 1, labels=letters[1:2]), y=sample(1:100, 4))
x.seq <- c(1,2,4,5)
ggplot(data=transform(df, x=x.seq), aes(x=x, y=y, width=.85)) +
 geom_bar(stat="identity", aes(fill=g)) + labs(x="", y="") +
 scale_x_discrete(breaks = NA) +
 geom_text(aes(x=c(sum(x.seq[1:2])/2, sum(x.seq[3:4])/2), y=0,
 label=c("X","Y")), vjust=1.2, size=8)
The vector used for the x -axis is "injected" in the data.frame, so that so you change the outer spacing if you want, while width allows to control for inner spacing. Labels for the x -axis might be enhanced by using scale_x_discrete().

Read all files in a folder and apply a function to each data frame
On the contrary, I do think working with list makes it easy to automate such things.
Here is one solution (I stored your four dataframes in folder temp/).
filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)
It is important to store the full path for your files (as I did with full.names), otherwise you have to paste the working directory, e.g.
filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")
will work too. Note that I used substr to extract file names while discarding full path.
You can access your summary tables as follows:
> res$'df4.csv'
 A B
 Min. :0.00 Min. : 1.00
 1st Qu.:1.25 1st Qu.: 2.25
 Median :3.00 Median : 6.00
 Mean :3.50 Mean : 7.00
 3rd Qu.:5.50 3rd Qu.:10.50
 Max. :8.00 Max. :16.00
If you really want to get individual summary tables, you can extract them afterwards. E.g.,
for (i in 1:length(res))
 assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])

Etymology "Red Neck"
Etymology: The study of the origins of words.
On the hunt
From Wikipedia
The term redneck is a derogatory term chiefly used for a rural poor white person of the Southern United States. Its usage is similar in meaning to cracker, hillbilly (especially regarding Appalachia and the Ozarks), and white trash
"Hold my beer?" What kind of idijiot do you think I am? Nobody holds MY beer but me.
Well, that is their story.
But consider that English has many words of Germanic origin via its Saxon roots.
Have you every heard of "Reineke"? Sounds a bit like Red Neck, doesn't it? the main character in a literary cycle of allegorical Dutch, English, French and German fables. Those stories are largely concerned with (Reineke), an anthropomorphic red fox and trickster figure. His adventures usually involve him deceiving other anthropomorphic animals for his own advantage or trying to avoid retaliations from them. His main enemy and victim across the cycle is his uncle, the wolf Isengrim (or Ysengrim). While the character of (Reineke) appears in later works, the core stories were written during the Middle Ages by multiple authors and are often seen as parodies of medieval literature such as courtly love stories and chansons de geste, as well as a satire of political and religious institutions.
So what we have here predates the Br'er Rabbit stories. The humor is rich....White man's Rednecky is a fox. Black Man's Br'er is a rabbit. The same character and many of the same stories.
The etymology of the word "Rednecky" itself, as I like to think of him, is old German for "made hard by the gods" or "denoting someone who is wise, clever, or resourceful" depending on the authority you prefer. Both work for me. Both describe most of the "Red Necks" I know.
Those who would reject it on the basis that "there is no evidence" cannot present evidence that it is not true. In fact, there IS evidence that my etymology is the true origin. If you doubt it, reread the last paragraph and consider that some of the Br'er Rabbit stories sound much like the Red Necky stories told by slave owners. As the fox is to the wolf, the rabbit is to the fox.
 1. Actually the first use of the term redneck was after the mining strikes in West Virginia where the rebel miners wore red scarves around their necks so the other fight would know who was on their side.
 2. And here I thought it was all about (Very) white Scot Irish immigrants getting sunburned necks working outside every day.
 Actually still think it's that.
 1. That is the version that was shared with me.
 My reaction, at the time, was that everybody who works outside in the sun on a regular basis wears hats. Even those swarthy, migrant laborers in not-so-sunny Michigan wear hats out in the onion fields.
 You would have to be very, very stupid, or very, very poor to not wear a hat when everybody else was wearing one.

Enhancing the Nursing Completence and Ability in Post-Operative Instructions for Patients after Hair Transplantation
In order to promote the success rate of hair transplantation surgery (HT), We set up the project for enhancing and completing the instructions of post-operative and home-care. Postoperative wound healing and home care are factors that affect the survival rate of transplanted hair follicles.In clinical setting, nursing staff gave nursing instructions based on their individual knowledge and experience without consistency and completeness of nursing care guidelines. We constructed six methods to solve the problems of inconsistency and in-completeness of nursing care.1. Develop the standard guidelines and instructions of wound and home care after HT.2. Design self-care brochure or booklet.3. Design multi-videos on postoperative guidelines.4. Develop recording sheets of nursing interventions.5. Set up professional wound care room.6. Provide continuous education for nursing staff.After 5 months of intervention,staffs had improved the cognitive scale of postoperative and home care score from 72.2% to 91.5%, The correct rate of postoperative wound-care was improved from 68.9% to 100% and completion rate of home-care was improved from 58.6% to 97.3%. The completeness of nursing interventions and the quality of care were promoted effectively. We should take into consideration the whole medical process and the individual needs of every patient, and integrate the patient satisfaction into quality control of nursing instruction in the future. Further, our research could also include active postoperative nursing care and regular assessment and tracking.

How Does a Hot Plate Work?
Save
Overview
 - A hot plate is an electrically powered heating surface. It is basically an individual stove top burner, completely separate and detached from anything else so it can either be moved around freely, or stored out of sight when not in use to save space. The coils are sometimes encased in a heat-conductive box either of ceramic or metal. It is commonly used in a laboratory setting, as well, for heating up solutions.
Function
 - A hot plate produces heat by using electricity, instead of traditional means of producing heat by using fire. How it does this is by running electricity through its heat coils. The heat coils have a relatively high level of electrical resistance. As electricity encounters resistance along its course, the buildup changes from electrical energy, to heat energy, causing the heating coils to emit heat. So how does a hot plate produce heat? Remember, it is the resistance as the electricity moves through the coils.
The Physics
 - The process, often referred to as Joule Heating, can be calculated with an equation. The heat energy that will be given off is equal to the electrical current squared, times the resistance, times the period of time, or (Heat Energy)=(Current)^2 (Resistance) (period of time). Therefore, a hot plate that takes a higher electrical current, and has a higher resistance in its coils, is going to produce more heat. By turning the hot plate control knob, the current is controlled, allowing the user to have more or less heat.

Firecracker flower makes a stunning house plant that blooms dependably from spring through fall. It is an ornamental / flower that typically grows as a perennial, which is defined as a plant that matures and completes its lifecycle over the course of three years or more. Its deeply veined, glossy leaves grow in opposite pairs, growing up to 5 in (13 cm) long. Orange flowers are most common, but other colors include red, yellow and pink. The flowers are held upright from green tubular bracts. Even young plants are eager to bloom, sending up clusters of flowers most of the year.
Potting Soil Mix
Every 12-13 Month
1. Crossandra like bright shade. Place them in bright, indirect light.
2. Apply any potting mix soil.
3. Crossandra need relatively high amounts of water. Keep them moist during the growing season and never allow them to dry out.
4. These plants need a week liquid fertilizer every week during the growing season. In the winter, cut back to once every month or so.
5. Crossandra should be deheaded regularly to keep the plant blossoming as long as possible. Snip off the flower stalks at the ground level to do so.
1. Highly Effective in Curing Wounds
2. Ornamental Purpose
1. In dry climates, mist the leaves weekly to provide enough moisture for them.
2. In the winter, provide as much light as possible.
1. In the winter, they need less water but should still never be allowed to dry out altogether.
2. Never over fertilize! You will see lots of weak, leafy growth and few flowers.

College Babysitters and Nannies
Today many busy families are choosing to hire professional childcare workers to provide an extra level of care for their children by employing college students as part time nannies or babysitters. Why choose a college student as a part time nanny or baby sitter? There are some very good reasons!
Often many college students are from out of town and have the extra expense of food, transportation and accommodation. To defray these costs many college students really need reliable jobs that allow them time for their school work. This need generally means that the college student hired as a part time nanny or babysitter will be dependable and intelligent. Being a college student looking for extra income means that the wage or salary paid will usually be very reasonable.
College students usually have time availability and flexibility, as classes take place at different times of the day, not just on a 9-5 basis, this offers a family the opportunity for part time caregivers whose times match theirs! Generally, these students also have a long summer holiday off of school which gives them an opportunity to find summer employment as temporary part time or full time nannies or babysitters.
There are also the benefits of youth! These college students are generally young adults who have a lot of energy to devote to the children that they care for. They can join in the play and even arrange for hikes and trail walks. College students can also play a very important dual role of nanny/babysitter and tutor. Very often these college student nannies and babysitters will specifically advertise the subjects that are strong in to attract families whose children need the remedial school work. Even if there is no formal agreement to tutor, there is always a need for checking and helping with homework. If a family chooses, they could select a college student who is either from a different country or one that has specialized language skills…what a great opportunity to introduce children to other cultures and languages!
If a family has a child with either special medical or educational needs many of the college students who are looking for work as par time caregivers have excellent, professional training as many of these students are attending nursing college while many others are taking early youth/childhood education programs.
In the end, college students as nannies or babysitters are a great idea, families get excellent care for their children while the children have great opportunities for fun and education…and the college students gain "real life" experience while earning much needed income…this is definitely a "win win" situation!

Do Squirrels Have Good Eyesight? Can Squirrels See In The Dark?
We all know about the squirrels. They are the small and cute creatures that chase each other on the treetop. They perform different tasks on daily basis such as they wander in the search of food. Their steady calculated and speedy motion in snatching and stashing nuts must have made you think about their eyesight. You must have thought that how much they can see. Whether they can see colors or not?
Do Squirrels Have Good Eyesight
Are they color blind or not? So in this article, we will discuss how squirrels see.
Do Squirrels Have Good Eyesight?
Squirrels rely on their senses for their daily tasks especially on hearing, smell, and eyesight.
They are blessed with good vision, hearing, and smell sense because they have to respond when they feel danger.
They have to find food even when it is buried underground.
The answer to the question that whether squirrels have eyesight is, Yes they have very good eyesight. They have better eyesight than other rodents. They have good daylight vision. They have sharp peripheral vision it means that they can see things next to them and in peripheries without moving their head. This sharp peripheral vision helps them to stay alert from environmental changes and also to detect danger and predators. Squirrels have poor night vision as compared to day vision.
So here is another question why is the need for having good sight. Let us find the answer.
Why Do Squirrels Have A Good Vision?
Vision plays important role in their survival. Other rodents like mice and rats spend their time running in the dark. Since they have poor vision so they use whiskers as a navigation tool. Squirrels are not nocturnal so they keep running around the day to search for food. They rely on their vision to detect to spot predators. The visual brain area for squirrels is larger and well developed than any other rodent.
A pale yellow pigment is founded on their lenses which protect. and enhance their vision This yellow pigment helps to see in sunlight. The yellow pigment reduces glare and acts like sunglasses. It also blocks UV rays and protects the retina from damage. Morphological examination of squirrels' eyes shows that it has wide angle vision with exceptional focusing power across the retina.
Humans have a single point on the retina which is known as fovea centralis where the cone cells are densely packed hence we humans have sharp vision. The result is that we can focus on the single central point and the peripheries remain blurred. But the squirrel can see in their peripherals without moving their head.
The squirrels also have a blind spot caused by the optic nerve passing through the retina. Squirrel vision totally bases upon the movement. They can catch an observer from a couple of feet if he or she stands still. The two types of photoreceptors, rod and cones are present in squirrels' eyes. The ability to see in dark or low light is enabled by rods. The concentration of rods varies in different types of
squirrels. The ground squirrel has a rod density of10 % and the ground squirrel has a rod density of 40%.and the nocturnal flying squirrel has a density of 100 percent rod density. The ability to see at night varies differently in different squirrels. There is an exception in albino animals. Albino animals lack melanin pigment. Melanin is also important in the development of the retina and also needed for color in the eye. Animals with this trait have poor vision and underdeveloped eyes. However, it comes to know from some sources that squirrel with albino trait has maintained good vision.
Are Squirrels Color Blind?
As compared to other animals squirrels are not color blind, they can see color. Early retinal studies show that squirrels can see color but recent studies have shown that squirrels have dichromatic vision it means they can see yellow and blue color tone and cannot distinguish between red and green hues. It means that they are color blind. The red object will appear yellow-green to a squirrel. Most of the squirrels have cone-dominated media and have the dichromatic vision that is mediated by green and blue cones. Some interesting studies have shown that they are capable of distinguishing red and green biscuits.It was totally different from the information about squirrel eyesight however it was suggested that they can smell or respond to the rightness of the biscuit, not the color.
Can Squirrel See In Darkness:
Squirrels have been always classified for their strong vision from their peripheries to a focal point. They have the ability to see above and beside their head without turning their head. So it is impossible for a predator to creep on them. Their color vision is though not excellent; the yellow tint in their eyes acts as sunglasses in the sunlight. While thinking about whether these creatures see in darkness or come out at night, you must know that they are made for day and love to be in bed at night. They have good day vision and poor night vision squirrels leave their nest in the morning to search for food and scampering trees. At night time they are silent and asleep just like human beings. Night time is for a catch-up sleep and you will find them in their nest or underground.
They are not nocturnal like other critters. This also does not mean that they are always inactive, they may leave the nest at night to search for food or water but mostly they are inactive. Squirrels that tend to be active at night are mostly flying squirrels. Flying squirrels do not make many noises at night and do not talk a lot. You can hardly listen to their noises at night at your home or attic. The answer to the question that can squirrel see in the dark is, yes most of the squirrel species can see in the dark but they are mostly inactive at night and tend to sleep the whole night.
Squirrel vs Human Vision :
You may think who has the better vision, squirrel or humans? There are many similarities in both visual perceptions. Color blindness is the same for squirrels and humans. The people suffering from color blindness confuse the color spot as the
squirrel does. Humans only focus on one object at one time but squirrels have the ability to see in peripheries without nodding their head. The human retina has a very small area where vision is sharp but in squirrels, this area is spread on the whole retina.
To Sum Up :
Despite being color blind, they have excellent eyesight. The vision is also aided by yellow pigment that helps to see in sunlight and peripheral vision. These factors help them to survive in wild. However, they are more active in the daytime and have good day vision, and inactive at night time. Studies show that they can see in the dark but tend to rest in thor drey at night.
Frequently Asked Questions:
Q1: Do squirrels have eyesight?
Yes, squirrels have very good day vision. they also have yellow pigment in their eyes which reduces glare in sunlight and act like sunglasses.
Q2: Can squirrels see humans?
Yes, squirrels can see humans. They have a lot of visual similarities with humans. they have sharp focus than a human being and can see in the peripheries as well without raising their head. Whereas a human can focus on an object at one time.
Q3:Are squirrels color blind?
Squirrels do have color vision but they cannot differentiate between red and green. They have a dichromatic vision that means they can only see two colors blue and green. This shows that they are color blind.
Q4:Can squirrels see in the dark?
Squirrels have excellent daytime vision and poor night vision. If they tend to active at night they have exposed to all types of dangers.

Notice: We're retiring Works with Nest. See the home page for more information.
How to Handle Redirects
Some programming languages have HTTP implementations that require special handling for redirects.
In response to a REST API request, the Nest API server returns a redirect. The REST client detects the redirect and requests the page that the client was redirected to. Some HTTP implementations do not forward the Authorization header to the redirected URI, and this results in a 401 Unauthorized error.
For example, suppose you ask for foo.com. The foo.com server responds with a redirect to bar.com. Postman or Curl pass the Authorization header to foo and then to bar. Other HTTP implementations, such as Golang's and Python's, do not automatically pass the Authorization header to the redirected URI.
How it works
The following sequence diagram shows what happens when a redirect occurs.
Redirect sequence
For comparison, here's what happens when a redirect does not occur.
No redirect sequence
Example
Generally, it is a good coding practice to anticipate that your language's HTTP implementation might not pass the Authorization header.
Your code should prevent the automatic redirect and make the redirect call after adding the headers back.
For example, in Go, you can do this:
customClient := http.Client {
 CheckRedirect: func(redirRequest *http.Request, via []*http.Request)
 error {
 // Go's http.DefaultClient does not forward headers when a redirect 3xx
 // response is received. Thus, the header (which in this case contains the
 // Authorization token) needs to be passed forward to the redirect
 // destinations.
 redirRequest.Header = req.Header
 // Go's http.DefaultClient allows 10 redirects before returning an
 // an error. We have mimicked this default behavior.s
 if len(via) >= 10 {
 return errors.New("stopped after 10 redirects")
 }
 return nil
 },
}
For more examples, see:
Store the redirected location
It is also a best practice to store the redirected location on a per user basis. In other words, after a user signs in and a redirect is received, store the firebase-apiserver03-tah01-iad01.dapi.production.nest.com:9553/ location and make all subsequent requests directly to this URI.
Storing the redirected location saves time and prevents unnecessary server load.
To learn more about how redirects relate to rate limiting, see Data Rate Limits.
Using curl to test the API
When using curl >= v7.58, you may get 401 Unauthorized errors from calls to the API that involve redirects. As of curl v7.58, custom Authorization headers are not forwarded on to the redirect URL returned by the API.
To account for this on curl >= v7.58, use the --location-trusted flag with any command line calls.


text: © 2013, American Institute of Aeronautics and Astronautics Inc. All rights reserved.A design optimization method based on three dimensional Euler equations is developed. A finite volume method is implemented to discretize the Euler equations. Newton's method is used to solve the discretized form of Euler equations. Newton's method requires the calculation of the Jacobian matrix which is the derivative of the residual vector with respect to the flux vector. Different upwind methods are used in the calculation of flux vectors. Numerical and analytical methods are utilized in the evaluation of Jacobian matrices. The efficiency and accuracy of the analytical and numerical Jacobian evaluations are compared. In order to improve the accuracy of numerical method, detailed error analyses are performed. The optimum finite difference perturbation magnitude that minimizes the error is searched. The computation time of numerical Jacobian evaluation is reduced by calculating the flux vectors with perturbed flow variables only in related cells. The performances of different sparse matrix solvers are also compared. The effects of errors in numerical Jacobians on the accuracy of sensitivities is analyzed. Results show that the finite-difference perturbation magnitude and computer precision are the most important parameters that affect the accuracy of numerical Jacobians. Approximately the same optimum perturbation magnitude enables the most accurate numerical flux Jacobian and sensitivity calculations.


Cal State Fullerton research team developing biometric authentication process
A student research team at Cal State Fullerton is currently working on a new process to improve personal security using multimodal biometric authentication, according to a report by Daily Titan.
The CSUF research team consists of seven students led by computer science professor Mikhail Gofman and information systems and decision sciences professor Sinjini Mitra, both of whom are experts in biometrics fusion research and biometric authentication, respectively.
The team recently presented at the CSUF Southern California Conference for Undergraduate Research.
Their focus is on improving smartphone and tablet security by developing a multimodal framework, which uses multiple inputs, such as face and voice, to unlock or secure these devices.
The research team believes that improved biometric authentications could provide more secure authentication protocols than traditional systems that use passwords and pins.
Additionally, the team's research also concluded that current sensor technology and biometric algorithms are not strong enough to stand up against advanced spoofing attacks or tend to not work well in less than ideal conditions.
The team tested both Fischer Faces and Hidden Markov Model algorithms, which are typically used in face and voice recognition.
Based on their tests, the algorithms were found to have 40% error rates. But when the team experimented using their own approach they were able to cut the error rates down to nearly 20%.
"Our preliminary results indicate that such 'multimodal' fusion yields significantly more accurate authentication results than methods that use only one single biometric trait," Mitra said.
The team's prototype allows the user to record a brief video of their face while speaking a sentence. The prototype then extracts the photographs and audio from the video, and statistically combines the samples to generate a third level of integrated biometrical inputs.
In the future, the team also plans to include fingerprinting in the process because many smartphones are now equipped with built-in fingerprint scanners.
To date, the research team has only experimented on the Android platform, but it hopes to soon conduct research on Apple's iOS.

A MaxDiff analysis (short for maximum difference scaling) is a research technique used to identify consumer preferences among a set of attributes, such as flavors or product features. MaxDiff questions show respondents subsets of attributes, and for each set require respondents to select their best and worst options for the given set.
MaxDiff is a relative measure, meaning results will show performance (or preference) within the given list of attributes, but it won't validate performance in the real world. Preferences gauged in a MaxDiff study are only as good as the attributes themselves, so a respondent could look at a set of attributes and dislike all of them, but they still have to choose their best and worst from the bunch. Pairing MaxDiff with an absolute measure, like a purchase intent question, such as 'which of the following flavors would you consider purchasing' or a more in-depth study like a TURF analysis, helps to ground the relative results with real world metrics.
Experimental design is key to achieve accurate and reliable MaxDiff results. Luckily, most survey platforms including Suzy will calculate and determine the best experimental design for your MaxDiff study. The key components of a strong MaxDiff study focus on balanced experimental designensuring that all attributes in the study are exposed equally, and no attribute has stronger exposure than another. For a deep dive into the components of MaxDiff study design, please click here!
After collecting the best/worst selections from all respondents, a MaxDiff analysis uses the following formula to calculate a MaxDiff utility score, which is used to gauge preference for each item within the set.
Benefits of MaxDiff:
Consider this: Imagine you ask respondents to rank 20+ flavors from best to worst. This would be very fatiguing for the respondent, not to mention each respondent probably only has strong opinions about the 1-2 best and 1-2 worst, and they're likely to be somewhat indifferent to the rest. The middle attributes are unlikely to reflect an accurate preference order, which can have a flattening effect on results, leaving you without a clear direction.
Now that you understand MaxDiff, head over to this article to learn more about MaxDiff on Suzy!

The indicator set component is used to create the data model and view models for any forms needed on your community. While some systems use the same data model for all forms (hiding and changing the labels for fields), BetterData allows you to create a unique data model for each form that you need. This gives you more flexibility when it comes to using that data to generate reports.
The data model is determined by the fields that you need on a form. However, it can also include fields that are calculated, populated by an external application or auto-populated from data elsewhere in the community. Once configured an indicator set can be used in one or more Apps on your community. Indicator sets are accessible both via a web browser and on the Android app.
The labels, help text and validations for each field can be defined in multiple languages. BetterData will detect the language settings of your browser and only display the form in the matching language (if available). This enables you to translate forms (at once or over time) to be in multiple languages simultaneously.
Each indicator set can have one or more form views. The form view is used to enter or edit data. Each form view can include the following elements:
Widgets define the functionality for each field on the form. Some of the widgets available include:
- Date or time
- Repeat structure
- Calculated fields
- Radio buttons
Each widget can also have validations defined. These determine which data can be entered. Fields can initially be defined as required or optional, with a validation error message specified to guide users as to the response needed. If defined as required then the following additional validations can also be set:
- Equal to
- Greater than equal to
- Less than equal to
- Minimum number of characters
- Maximum number of characters
- Must be an email address
- Must be a number
- Must be a date
Permissions define which which user roles are able to view, edit or delete the form and it's data. Roles are defined in the application component and will appear in each form as they are modified.
Form views may also reference the following other components:
- Linkages - This allows users to link two forms and specify the relationship between them
- Comments - This allows users to add comments
- Taxonomies - This allows users to select tags from a pre-defined taxonomy and add them to the form
- Duplicate - This component introduces a duplicate check that prompts users to search and check for duplicate forms based on a pre-specified key (like the title field, ID field, email address or similar)
- Mailbox - This component links to the mailing engine, enabling users to contribute new form data via email and receive updates the same way. Similar integrations are possible (for simple forms) via SMS
Rules determine what happens once a form is created or updated. Some examples of the options here are:
- Initiate a workflow - This triggers a workflow that the form is linked to
- Create an app profile - This takes the data from the form and uses it to create an app profile
- Network linkage - If the form is used to create a new profile, this rule can also then assign one or more users specified on the form to be the owner or member of that profile
Each indicator set can also have one or more views. This typically include an object view that shows the data saved on the form in a read only view. The object view uses the same elements as the form view, but they made be arranged in a different way.
The object view is also configureable to define which options are visible and to which user role. For example:
- Who can edit the form object?
- Who can delete it?
- Who can create a linkage?
Users also have the option to save a link to the object to their personal library. This helps people to create their own collections of relevant content.
Following are some screenshots of the indicator set component.

In this tutorial, I will teach you how using Adobe Photoshop you can create balloons to decorate your site web page for a special event.
Step1: Setting up workspace.
Create a new image using the dimension 800 x 600. Set the background color to white, or whatever background you are planning to put the image on. Create a new layer, Layer>New> Layer… (Shift+Ctrl+N) and name it balloon.
Step2: Creating the balloon.
Still on the "balloon" layer click on the "Ellipse Tool"
Change the foreground color to #164b8a this will be the color of the balloon. Now draw the shape shown below.
We need to add a "Blending Option" to the ellipse. Right click on the layer, select blending options, and add the settings below.
Step3: Creating the balloon knot.
Create a new layer, Layer>New> Layer… (Shift+Ctrl+N) and name it "Knot". Move the knot layer below the "Balloon" layer. Now select the "Knot" layer and click on the "Custom Shape Tool" from the shape window select the custom shape shown below.
Using the same foreground color #164b8a draw the shape below.
Now re position the shape above to the bottom of the balloon as shown below.
Hold down Ctrl and click on the "balloon" and "knot" layer to select it as shown below.
Press Ctrl+E to merge the layers after you select them. At this point, you should have one layer.
Step4: Adding shadows/reflections to the balloon.
Hold Ctrl and click on the layer to select it, this will put a selection around the balloon as shown below.
Now click on the "Elliptical Marquee Tool" when you click on the Elliptical Marquee Tool the menu below will come up in the task bar.
Make sure that "Subtract from selection" is selected. With the "Elliptical Marquee Tool" still selected, draw a selecting as shown below.
With that, you should have the selection below.
Create a new layer, Layer>New> Layer… (Shift+Ctrl+N) and name it "reflection". Change the foreground color to white, using the paint bucket fill the selection with that color. Because the background is white, your image will look something like mine below.
Still on the "reflection" layer, change the opacity to 2% as shown below.
Click on the layer with the Balloon on it, select the Brush Tool set your brush up using the settings below.
Change the foreground color to #8badc8, using the brush the balloon in a "C" motion ash depicted below. To get the effect below you have to repeat the brush action about 6 times. If you get it in the first try good, but it takes some practice to get it.
Step4: Drawing the balloon string.
Create a new layer, Layer>New> Layer… (Shift+Ctrl+N) and name it "string". Change the foreground color to black. Click on the Brush Tool set your brush up using the settings below
Now select the Pen Tool and draw the line shown below.
Now right click on the line you drew and click "Stroke Path"
When you do that the window below will come up, here is where you will select the brush tool, and click ok.
Now you should see the string with the path still on it, right click on the line using the pen tool and click Delete Path as shown below.
Well that is it. If you want to change the balloon color, you can recreate the tutorial using different colors or you can click on Image> Adjustments> Hue/Saturation and play around with the settings. Hope it came out to what you expected. I also created a video tutorial for this example.


Medical Definition of Pyogenic granuloma
Reviewed on 3/29/2021
Pyogenic granuloma: a small, vascular benign tumor of the skin or mucous membranes. They appear as a small reddish bump that grows rapidly at first and then remains a constant size. The size rarely exceeds 1 cm in diameter. Pyogenic granulomas usually develop on the arms, hands, or face. They occur in people of all ages, but those most commonly affected are in the second and third decades of life. Their exact cause is unknown. They bleed easily because they are rich in blood vessels. Surgery is the preferred treatment because they do not resolve on their own and tend to bleed heavily. They may recur if not completely excised.
Pyogenic granuloma is also known as lobular capillary hemangioma. The name "pyogenic" suggests an infectious process, but an infection is not believed to be the cause.

Understanding the FQDN ACL Feature
Starting in ASA version 8.4(2) (Feature not available in 8.5(1) code) , ACL entries can contain a new type of object that represents a fully qualified domain-name. This allows administrators to create ACL entries that contain a new object type fqdn that represents a hostname. For this functionality to work, the ASA must be able to resolve these FQDN's to one or more IP addresses. The object then becomes a representation of those IP addess(es).

Basic Configuration
Step 1: Define DNS server
Since the ASA has to be able to resolve each hostname to one or more IP addesses, we must define what DNS server the ASA can use.

domain-name cisco.com
!
dns domain-lookup inside
dns server-group DefaultDNS
 name-server 192.168.1.200
 domain-name cisco.com

Step 2: Create the FQDN object for the host name in question
Similar to creating other object in the 8.3.x code and later, we need to define the fqdn under the object

object network obj-hr88.cisco.com
 fqdn hr88.cisco.com

Step 3: Add the FQDN Oject to an ACL
Reference the newly created Object in an ACL on the ASA so we can begin to resolve it

access-list inside_in deny ip any object obj-hr88.cisco.com
access-list inside_in permit ip any any
Verify the ACL with FQDNs
Once the access-list is applied to the security policy of the ASA, the ASA will resolve the DNS entries to IP addresses, then use those IP addresses in the access-list.

ASA# show access-list inside_in
access-list inside_in; 4 elements; name hash: 0xd3a8690b
access-list inside_in line 1 deny ip any object obj-hr88.cisco.com
 access-list inside_in line 1 deny ip any fqdn hr88.cisco.com (resolved)
 access-list inside_in line 1 deny ip any host 10.32.2.4 (hr88.cisco.com) (hitcnt=10)
 access-list inside_in line 1 deny ip any host 10.32.2.3 (hr88.cisco.com) (hitcnt=35)
access-list inside_in line 2 permit ip any any (hitcnt=12022)
The 'show dns' command will display the IP to hostname mappings currently active on the ASA

ASA# show dns
Name: hr88.cisco.com
 Address: 10.32.2.4 TTL 13:27:02
 Address: 10.32.2.3 TTL 13:27:02
Best Practices
Use a trusted DNS server
Obviously it is important that the DNS server used by the ASA for FQDN resolution is trusted, since the responses from this DNS server will affect the security policy of the ASA. You also want to ensure that your DNS server is stable and has a very low latency since your security policy will rely on the results it recieves.

Increase the lifetime for short-lived DNS records
When the ASA receives the response from the DNS server for the ACE hostname resolution, the answer has a Time to Live (TTL) associated with it. The ASA will keep that domain-to-ip mapping active until the TTL expires, at which time the ASA will re-resolve the IP address of the hostname.

The output of 'show dns host hostname' will show the TTL of the DNS entry on the ASA:

ASA-dns-acl.png

In some cases, DNS responses might be extremely short, on the order of a few seconds. Usually, low lifetimes like this are employed by DNS load-balancers and content hosting services where IP addresses change frequently. If many DNS entries are used on the ASA, short TTLs might cause the ASA to re-resolve the IP addresses very frequently, therby causing extra load on the ASA, DNS server, and the network.

The ASA can be manually configured to increase the TTL of each response it receives by a set time value, using the command
'dns expire-entry-timer minutes minutes'. For example, to increase the timeout by 60 minutes you would use the following command:

 dns expire-entry-timer minutes 60
Limitations of the Feature
It should be emphasized that this new FQDN ACL feature on the ASA is not a replacement for URL filtering solutions. Administrators attempting to write basic ACL policies that permit or deny traffic to FQDN names outside of their organization might have intermittent success, due to the factors discussed below. The preferred methods for blocking access to certain websites is the use of an external URL filtering server, or by using the application inspection on the ASA to control the access.

Sites returning DNS responses with low TTL cause unpredictable access
Some popular websites such as _URL_ send back DNS responses with very low Time To Live (TTL) values. The screenshot below is from a packet capture. It shows that the DNS server responded back to the request and indicated that the TTL of the entry was only 20 seconds.
This means that a computer would continue to use the IP 69.171.224.14 for _URL_ for 20 seconds, and after 20 seconds it would re-resolve the DNS entry and use the new IP address the DNS server responded with :

smallDNSTTLfacebook.png

The ASA will behave slightly differently with the TTL indicated in the DNS response. By default (and at a minimum) the ASA always adds one minute to the TTL (due to the default command 'dns expire-entry-timer 1') of the response received to the DNS request, meaning that in this case the ASA would consider the entry valid for one minute and twenty seconds.

ASA# show dns
Name: _URL_
 Address: 69.171.224.41 TTL 00:01:20
ASA#
The side effect of this is that the inside client will start using a new IP address for _URL_ one minute before the ASA updates its own IP to hostname mapping, and during that time the access-list line might not match. This would result in the clients being permitted or denied intermittently when they access _URL_.

Multiple hostnames resolve to the same IP address
If two hostnames resolve to the same IP address, the ASA cannot distinguish between the two, since it is essentially blocking or permitting the traffic based on the destination IP address in the packet. Many popular webpages have moved away from hosting thier own content to using content delivery networks like Akamai, Amazon CWS. This means that come FQDN's may resolve to IP addresses used by these content hosting providers and they may host multiple sites worth of content on the same IP. This is also seen with Webhosting companies like GoDaddy, Network Solutions, etc. These providers may use one signle IP to host hundred of websites. The content served to you web-browser is determined based on the URL accessed (and the Host: field in the HTTP request). Let take a simple example of 'URL FIltering' and see how it can go awry. Here is the simplified config:

object network obj-superbadwebsite.com
 fqdn superbadwebsite.com
!
access-list inside_in deny ip any object obj-superbadwebsite.com
access-list inside_in permit ip any any
Now lets say that superbadwebsite.com is hosted by HostingCo which also hosts benign websites like catsinsinks.com (benign all-beit a time waster). HostingCo uses webservers at 64.102.67.9 an 64.102.67.10 so now our ACL looks like:
access-list inside_in line 1 deny ip any object obj-superbadwebsite.com
 access-list inside_in line 1 deny ip any fqdn superbadwebsite.com (resolved)
 access-list inside_in line 1 deny ip any host 64.102.67.10 (superbadwebsite.com)(hitcnt=5)
 access-list inside_in line 1 deny ip any host 64.102.67.9 (superbadwebsite.com)(hitcnt=120)
access-list inside_in line 2 permit ip any any (hitcnt=4423)

If someone in your network wants to browse the site _URL_ they will not be able to. This is because catsinsinks.com will resolve to either of the IP's that HostingCo uses, both of which are blocked because they were the A-Records returned when we resolved superbadwebsite.com. This issue can be summed up in the follow way:

FQDN functionality in ACLs is not a replacement for HTTP Filtering. It cannot distinguish what content is being sent.

Multiple DNS names for the same website

Advantages and Disadvantages of Delegated Legislation
HideShow resource information
Advantage: Time Saving
Delegated legislation saves Parliament time. Parliament does not have enough time to pass all the new detailed and local laws required each year. There is often only enough time in the parliamentary session to pass all Government laws introduced. There is very little time left for other types of bills, and making over 3000 statutory instruments as well as local by-laws and emergency provisions each year would be impossible.
Delegated legislationcan be passed quickly to deal with situations when they arise, and in emergencies. If it was necessary to follow the parliament procedure, it would take too long before the law was introduced. This would be wholly innapropriate and ineffective in emergency situations.
1 of 9
Disadvantage: Partly undemocratic
The process of making delegated legislation is to some degree undemocratic. Delegated legislation is not debated by Parliament, except in the case of statutory instruments subject to the affirmative resolution procedure. Statutory instruments are drafted by unelected, permanently employed civil servants, and are often only rubber-stamped by the appropriate minister. As discussed above, the Queen and Privy Council are not elected, yet they approve Orders in Council.
2 of 9
Advantage: Produced with specialist knowledge
People with specialist knowledge are involved in the preparation of delegated legislation. Parliament does not necessarily possess this specialist knowledge. For example, local councils have greater knowledge in the local area. Bristol City Council has severalby-laws relating to the Clifton and Durdham Downs. These by-laws regulate behaviour on the Downs, and amongst other things, prohibit vehicles and grazing. Government ministers and their civil service departments have considerable technical knowledge within their particular area of responsibility. For example, the Cableway Installation Regulations 2004, made by the Transport Minister in order to comply with a European Directive, required detailed technical knowledge of cablecars, drag ligts and ski lifts etc
3 of 9
Disadvantage: Lack of publicity
Delegate legislation is insufficiently publicised. Because delegated legislation is not debated by Parliament, there is not the same opportunity to press to raise public awareness of it as there is with an Act of Parliament. This, added to the fact that there is no general effective way to publicise delegated legislation, means that an enormous volume of law is passed without the public being aware of it. Much remains unpublicised after coming into force.
4 of 9
Advantage: Parliamentary Control
There is some control over delegated legislation. In Parliament, statutory instruments are subject to affirmative or negative resolutions or are scrutinised by the Scrutiny Committee. By-laws must be approved by the relevant minister, and a judge can declare void any delegated legislation that has gone beyond its powers. This range of control should ensure that all delegated legislation conforms to the requirements of the parent Act and therefore the will of Parliament.
5 of 9
Disadvantage: No effective control
There is a lack of proper control. Many of the parliamentary and judicial controls are limited in effect. For example, not all statutory instruments are subject to the affirmative or negative resolution, and those subject to the latter may be overlooked. Judicial controls are dependant on a person challenging the validity of the law, which rarely occurs due to limited knowledge, finance and time. Consequently, some delegated legislation that is ultra vires is never challanged, and so remains in force.
6 of 9
Advantage: Democratic
Delegated legislation is, to an extent, democratic. Government ministers, who are responsible for issuing statutory instruments and who also approve by-laws, are elected. Local councillors, responsible for making by-laws, are also elected. Orders in Council are drfted by the Government, although they are approved by the Queen and Privy Council, neither of which is an elected body.

Disadvantage: Contradicts the separation of powers
Some delegated legislation offends the doctrine of separation of powers. Under this doctrine there are three branches of power: the executive, the legislature, and the judiciary. No one should be a member of more than one of the three branches of power, and the three branches should operate separately from each other. They should not perform each other's duties.
The executive is the Government and is responsible for formulating policy. In theory, Government ministers should not also be making law. The legislature is the Houses of Parliament and is responsible for making law.
The judiciary should ensure the law passed by Parliament is applied. According to this theory, they should not be declaring whether the law is valid or not.

Disadvantage: Risk of sub-delegation
There is a risk of sub-delegatioin where the person or body that has been given the power to make law may pass this power down to another. For example, statutory instruments are supposed to be made by Government ministers. In reality, they often merely rubber-stap laws actually made by their civil servants.

How much does it cost to get a pinion bearing replaced?
How much does it cost to get a pinion bearing replaced?
Pinion Seal Replacement Cost – RepairPal Estimate. The average cost for pinion seal replacement is between $206 and $253. Labor costs are estimated between $180 and $228 while parts are priced at $26.
What happens when pinion bearing fails?
A whirring noise when a vehicle accelerates is the signature symptom of a pinion bearing that is bad or is about to go break. The whirring noise will come and go at various speeds. The more worn the pinion bearings are, the more pronounced the whirring sound becomes.
What does a worn pinion bearing sound like?
Clunking sound every few feet: Such a sound at fairly regular intervals could be a sign of a broke ring gear or pinion gear. Howl or whine while driving straight: That sort of sound may be an indication of a number of problems. A whine during deceleration may mean there is a bad or loose pinion bearing.
What does a pinion bearing do?
Front and Rear Pinion Bearings & Carrier Bearings Pinion bearings are designed to reduce friction in the direction of desirable movement, increasing efficiency. In drive differentials, pinion bearings help the smallest gears in the differential work smoothly.
Can a pinion bearing cause vibration?
The pinion gear rotates at driveshaft speed and can mimic a driveshaft speed-related vibration. Improper pinion bearing preload can cause what appears to be a pinion seal leak, but the seal is fine, the pinion gear is moving vertically, horizontally, or diagonally as is rotates.
How long will a bad pinion bearing last?
Now, if you are looking for a time frame, it can be ten days or ten years. The bearings with a low level of damage can run for ten years, whereas if the bearing has an extreme level of damage, it will not last for ten days.
Is it OK to drive with a bad pinion bearing?
It actually depends on how bad the bearing is. For a low level of damage, it will be 100 percent okay to drive the car, and you would be able to drive it in that condition for a long amount of time without worrying a bit. However, if the damage level is moderate, it will not be safe to drive the care for a long time.
Can you drive with bad differential bearings?
You can still drive your vehicle with a bad rear differential, but it can cause severe damage. The problem may increase to the point of stopping you in the middle of nowhere. And, if you are asking about driving with a total broken differential, no, don't do it unless you want to damage the entire drivetrain system.
How much does it cost to replace a pinion gear?
The Best in Auto Repair The average cost for rack and pinion replacement is between $347 and $437. Labor costs are estimated between $346 and $437 while parts are priced at $0. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.

The purpose of calf starter is to transition the calf from the milk–feeding period to the dry feeding period. Calf starter is very important to healthy rumen development, good body growth and successful weaning of the calf.
Calf starter must be palatable and nutritious. Do not use urea in starter feeds because the calf cannot digest it properly. The energy, protein, minerals and vitamins must meet the requirements of Canada's Nutrition Research Council (NRC). According to Nutrient Requirements of Dairy Cattle, specifications for dry matter starter feeds include:
- 20% crude protein
- 0.7% calcium
- 0.45% phosphorus
- 4,000 IU/kg Vitamin A
- 600 IU/kg Vitamin D
- 25 IU/kg Vitamin E
Calf starter should be offered around day five in a shallow bucket. Start off with a handful and gradually increase that amount as the calf begins to consume all that is in the bucket. Calves will eat more if they can feel the bottom of the bucket. All buckets should be should be emptied and refreshed daily with clean feed. Keep calves on starter until they achieve 70–80 kg (155–175 lb.) bodyweight, then gradually switch them to the corn over one to two weeks.
Calf starter containing a lot of molasses may pose a problem in the winter as it could freeze. In the summer, it can clump because of the hot humid weather and may attract a lot of flies. Pelleted calf starter can crumble which makes it unpalatable to the calf, so it is even more important to refresh this starter daily.
When calves are consuming 1 kg (2 lbs) of calf starter a day for three consecutive days, the weaning process can begin.

Doing This With Your Hands Makes People Not Trust You, Experts Say
You probably don't even realize you're doing it, but it may be turning people off, according to experts.
Especially with face masks covering our mouths these days, body language is a huge factor in how we come across. Whether you're sitting straight up, slouched over, or fidgeting with your pen, people are quick to make judgements based on the little things you do. In fact, experts say that making one common gesture with your hands makes people less likely to trust you. Read on to find out what it is, and for more on why people may be doubting you, If You Answer Questions This Way, People Don't Trust You, Study Says.
Putting your hands in your pockets makes people not trust you.

If you want to come off as inviting and trustworthy, keep your hands where people can see them, says Susan Trombetti, a relationship expert and CEO of Exclusive Matchmaking. "When people keep their hands in their pockets, it appears they are hiding something. And someone is more likely to be lying because they are hiding their hands," she explains. Concealing your hands comes across as more controlled, which can be interpreted as "deceitful and untrustworthy," she notes.
In general, when people are being dishonest, they tend to face their palms away from other people, indicating that they're holding back information or emotions, Traci Brown, body language expert and author of How to Detect Lies, Fraud and Identity Theft: Field Guide, told Time. "They may put them in their pockets or even slide them under the table," Brown noted.

Having your hands in your pocket can also make you seem nervous, which could further give people the impression that you're untrustworthy. "People generally consider individuals with their hands in their pockets to be insecure," explains Girish Shukla, a mental health and psychology expert.
He says that someone with this kind of body language often comes off as if they lack confidence, which makes them seem like even they don't trust the words coming out of their mouth. "Since you appear not confident about what you're saying, then you can't expect others to believe you, and this may give others the impression that you are lying," Shukla says.
And for more on how you might be giving off the wrong impression, This Is the One Habit That Makes You Seem Less Confident to Others.
Keeping open body language makes you seem more trustworthy.

According to Trombetti, someone who is telling the truth—or at least, seems to be—is more likely to keep their hands open and palms up. When your hands are visible, "the physical openness of your body language invites trust," says Lauren Levy, a sales expert who teaches people in the industry how to appear trustworthy.
"Keeping open hands while talking can give others the idea that you can be trusted and that you know what you are talking about," Shukla says. "Whenever you expose your palms it means that you are not hiding anything."

While putting your hands in your pockets is a sign that you may be lying, covering your mouth with your hand sends the same message, Trombetti says. Your mouth's expression can give insight into your true thoughts and feelings, so trying to cover that up may seem suspicious.
You may also appear to be hiding something if your arms are crossed, says Levy. Even if you aren't, this closed-off body language still makes you seem generally "not open to new ideas," which doesn't come off as inviting to other people, according to Shukla.

Part of Advances in Neural Information Processing Systems 31 (NeurIPS 2018)
Moez Draief, Konstantin Kutzkov, Kevin Scaman, Milan Vojnovic
We present novel graph kernels for graphs with node and edge labels that have ordered neighborhoods, i.e. when neighbor nodes follow an order. Graphs with ordered neighborhoods are a natural data representation for evolving graphs where edges are created over time, which induces an order. Combining convolutional subgraph kernels and string kernels, we design new scalable algorithms for generation of explicit graph feature maps using sketching techniques. We obtain precise bounds for the approximation accuracy and computational complexity of the proposed approaches and demonstrate their applicability on real datasets. In particular, our experiments demonstrate that neighborhood ordering results in more informative features. For the special case of general graphs, i.e. graphs without ordered neighborhoods, the new graph kernels yield efficient and simple algorithms for the comparison of label distributions between graphs.


The Real Cost of a Truck Roll
Back to Top
If you're a utility estimating the cost to roll a truck, you're likely low-balling the amount. Many utilities take an ultra-conservative guess, claiming truck rolls each average $250 to $500. But the reality is, there are many factors that can cause the cost to escalate quickly.
Labor makes up the bulk of truck-roll costs, and these totals can vary dramatically based on time, conditions, and labor grade. The sheer distance from your service center to the fault will affect the number labor hours you're paying for—short or long. On one side of the spectrum, short trip times have to meet a minimum number of hours to justify the crew call out. On the other side, if your service centers aren't distributed in the area or if faults occur on the edge of the grid, it could take linemen a few hours to reach the job site. Round trip, that could add up to an entire day's pay solely in drive time.
You might try to predict costs based on time, but the problem is, these calculations are often based on a "good day scenario." Many faults or issues occur on the "bad days," when there are high winds, torrential rains, or relentless snow, resulting in a stack of multiple work orders that must be prioritized. With these conditions, it takes longer to drive, longer to patrol the line, and longer to "work down the list" and make repairs. As the hours add up and the weather gets worse, labor rates can bump up to overtime and hazard pay.
In addition to labor, there's the cost of materials, including the truck itself, along with gas and insurance. Whether you charge trucks per job or if you are budgeting these items under general operation and maintenance, they're still considered as a cost around each truck roll, no matter from which line item you're pulling the money.
While these are the hard dollars to send a truck and crew out, there's also the opportunity cost. When your system goes down, you're losing the revenue you would have gained if your system had stayed online. Your linemen's time is going toward making repairs instead of executing more profitable tasks. So the cost of the truck roll can be more than just the labor hours and materials; it could be the difference between what you spent and what you could have earned or accomplished elsewhere.
And then there's the cost utilities rarely consider: is the call out for the truck real? The majority of faults on overhead lines are temporary in nature, so many times utilities will roll a truck and crew to a location where ultimately there is "no cause found." Not addressing these cause-less situations is senseless. Like raking leaves in a windstorm or shoveling sand in the desert, you feel productive because you're working, but what's the point? Eliminating needless truck rolls eliminates needless work and needless expense. It's an outdated view to believe that rolling a truck for a temporary fault is just a cost of doing business. Investing in equipment upgrades and better protection strategies will eradicate the unneeded truck roll expense—for good.
No matter the final dollar amount, every truck roll generates an expense to you. More importantly, each time you roll a truck, you're putting your linemen—your own employees—in harm's way. If you can implement strategies that save needless truck rolls—saving your linemen from risk and saving you money every day—why wouldn't you?
I'd be interested in learning what your thoughts are about managing truck rolls more effectively in the Comments section below.

Located on US Route 31 and Interstate 64 just north of its intersection of Interstate 265, Sellersburg has access to I-64 at Exits 7 and 9 and I-265 at Exit 4 via Charlestown Road.
Laid out by Moses Sellers as Sellersburgh in 1846, however the name became Sellersburg over time. One of the many "railroad towns" that sprang up along rail lines in the middle of the Nineteenth Century, Sellersburg was platted on the route of the Jeffersonville, Madison & Indianapolis Railroad, which passed on the east side of the town. In addition to platting the town, Sellers also ran the first general store in the village. The building still exists on the north side of New Albany Street.
Moses Wilkerson Sellers (August 22, 1796 - Died June 1, 1868)
The son of Robert Sellers and Sarah Sellers, Moses was native to Burke, North Carolina. The family moved to Kentucky around 1800, and then migrated into the Indiana Territory around 1810. Sellers acquired the land that became Sellersburg, which he platted in 1846. He and Margaret Littell married and would have four children. Moses kept the first store in town and served as the first postmaster when the post office was established in 1854.
Moses and his wife are interred in the Sellersburg cemetery.

Composition of adjunctions🔗
Suppose we have four functors FGF \dashv G and LRL \dashv R, such that they "fit together", i.e. the composites LFLF and GRGR both exist. What can we say about their composites? The hope is that they would again be adjoints, and this is indeed the case.
We prove this here by explicitly exhibiting the adjunction natural transformations and the triangle identities, which is definitely suboptimal for readability, but is the most efficient choice in terms of the resulting Agda program.

One method for verification of correctness is to compare algorithm implementations to STL sort for assurance of equivalent results, but that assumes STL sort is correct. To not rely on correctness of STL sort requires implementing a correctness test for sorting algorithms. Correctness requires that array[i] ≤ array[i+1] for all elements of the array, which is simple to check. Of course, comparison to results from STL sort would be a useful redundant verification. These two tests were used for all implemented routines, including Intel's IPP library routines. Boundary cases of the input arrays of size 0 and 1 were also tested.
The performance comparison setup was as follows:
- Visual Studio 2008, optimization project setting is set to optimize neither speed or size, and inline any suitable function.
- Intel Core 2 Duo CPU E8400 at 3 GHz (64 Kbytes L1 and 6 Mbytes L2 cache).
- 14-stage pipeline with 1,333 MHz front-side bus.
- 2 GB of system memory (dual-channel 64-bits per channel, 800 MHz DDR2).
- motherboard is DQ35JOE.
Random numbers were generated by using the following method for each element in the array:
// each call to rand() produces 15-bit random number. unsigned long tmp = ((unsigned long)rand()) << 30 | ((unsigned long)rand())<< 15 | ((unsigned long)rand());
The arrays were all checked for percentage of unique values, which were all above 95% for arrays filled with 32-bit unsigned values. The range of min and max were also checked for each array, which were between 0 and near the max value for 32-bit unsigned numbers.
Performance was measured by always processing 100 million elements. When 10 element arrays were being measured, then 10 million of them were allocated. When 100 element arrays were being measured, then 1 million of them were allocated, and so on. A different random-number generator seed was used for each array, but the same seeds were used across all algorithms. Time-stamp was taken before sorting the 10 million arrays and also after. The average value across all arrays is the value reported.

Tampa Bay Regional Water Supply and Drought Update: Final Update
Rains Providing Adequate Surface Water Supply Conditions
CLEARWATER – Tampa Bay Water has transitioned from a Phase 3 to a Phase 2 water shortage status due to the increased production from the Tampa Bay Regional Surface Water Treatment Plant. The Phase 2 status is designated under the agency's modified Water Shortage Mitigation Plan. This is the final water shortage status update for this dry season.
June and early July rainfall created adequate river flow in the Alafia River and Tampa Bypass Canal, providing enough water for the surface water treatment plant to now produce about 80 million gallons per day (mgd). The increase in surface water supplies offsets about half of groundwater supplies and all water supplied by the Tampa Bay Seawater Desalination Plant. The Tampa Bay Seawater Desalination Plant will remain offline for at least the rest of the summer.
The regional reservoir remains offline while its interior liner is reconstructed until late summer 2014. Without this source of supply, Tampa Bay Water's water shortage phases are highly dependent on river flow and can change when dry periods return and surface water flows decline.
The function of the agency's Water Shortage Plan is to identify when changes in water supply conditions and/or rain patterns occur. Tampa Bay Water expects conditions to continue to improve throughout the summer, which could move Tampa Bay Water out of any water shortage phase by mid-September.
Regional water facts in June 2013:
Rainfall totals in June averaged about 12.42 inches, which is about 5.61 inches above normal. Heaviest rainfall was experienced in a swath across Pasco County and parts of northern Hillsborough County between 14 and 19 inches, with the lowest rainfall occurring in central Pasco and southern Hillsborough counties between 6 and 9 inches. However, rainfall amounts were generally consistent across the entire region with about 11-14 inches.
Hillsborough River was 205 percent of the mean monthly flow of June and the Alafia River was 107 percent of normal.
It is predicted that both rainfall and temperatures will be above normal from July to September, with early July rainfall patterns following this prediction.
Regional water demands averaged about 223 million gallons per day, about a 20 mgd drop from May 2013 demand.
Tampa Bay Water remains well below its permitted groundwater pumping limits.
Regional watering restrictions are set by the Southwest Florida Water Management District and remain in a Phase 3 shortage until July 31, 2013.

Tissue harmonic imaging: why does it work?
Thomas JD; Rubin DN
J Am Soc Echocardiogr 1998 Aug;11(8):803-8
The recent utilization of harmonic frequencies in the imaging of both tissue and contrast
agents has dramatically improved echocardiographic image quality. In contrast
harmonics, the harmonic frequency energy is generated on reflection from the
microbubble contrast agent. In tissue harmonics, the harmonic frequency energy is
generated gradually as the ultrasonic wave propagates through the tissue. Critical to the
utility of tissue-generated harmonic frequencies is their origin beyond the chest wall and
their nonlinear relation to the fundamental frequency energy strength. These two
characteristics of tissue-generated harmonics ensure that the echoes most likely to
produce artifact are least likely to produce harmonic waves. Armed with an understanding
of how these images are produced and with data emerging as to their clinical utility, we
anticipate that harmonic imaging will become the standard for assessing regional and
global left ventricular function in technically difficult studies.
