Workshop at Université de Lille
'Health, consumption, and markets' (Santé, consommation et marchés): Søren Askegaard IVL/SDU participated in a Roundtable with the title 'Innovation of the concept of health and definition of tools'.
In both France and many other countries, the effects of market and managerial thinking in the healthcare area have been described thoroughly by healthcare professionals, journalists, researchers, and patients in the last few years.
In this workshop the participants will consider various forms of pressure that the healthcare system is influenced by today because of marketization: economic rationality, implementation of technology and digitalization, focus on scalation and quantity rather than human quality, and political and democratic demand for efficiency.
From a cross-disciplinary perspective, they aim to study the ways in which social relations in the healthcare sector are structured by practices and conventions that stem from the management and business area.

This chapter introduced some idioms for synchronization mechanisms, providing an overview of common coding practices for synchronization used in communication components for parallel programs. Selection amongst these idioms is the third main step towards the detailed design and implementation of coordination for a parallel application in the pattern-based parallel software design method.
The chapter's objective was to include classic synchronization mechanisms for implementing communication and synchronization components. These describe synchronization mechanisms that allow communication as described by a particular design pattern for communication components. However, as an initial attempt to the creation of a pattern system for parallel programming, the idioms here are not sufficiently complete or detailed to cover every synchronization issue within a parallel program: they need to be related to current pattern developments for concurrent, parallel and distributed systems.
The idioms for synchronization mechanisms presented here – the Semaphore idiom, the Critical Region idiom, the Monitor idiom, the Message Passing idiom and the Remote Procedure Call idiom – along with guidelines on their classification and selection, are intended to help the software designer decide which synchronization method best solves a given communication problem.

text: This paper describes the design of an efficient filter that promises to significantly improve the performance of second-generation Forward Looking Infrared (FLIR) and other digital imaging systems. The filter is based on a comprehensive model of the digital imaging process that accounts for the significant effects of sampling and reconstruction as well as acquisition blur and noise. The filter both restores, partially correcting degradations introduced during image acquisition, and interpolates, increasing apparent resolution and improving reconstruction. The filter derivation is conditioned on explicit constraints on spatial support and resolution so that it can be implemented efficiently and is practical for real-time applications. Subject to these implementation constraints, the filter optimizes end-to-end system fidelity. In experiments with simulated FLIR systems, the filter significantly increases fidelity, apparent resolution, effective range, and visual quality for a range of conditions with relatively little computation.

Nathan H. Dize deposited Intervening in French: A Colony in Crisis, the Digital Humanities, and the French Classroom in the group Race and Aesthetics in French and Francophone Culture on MLA Commons 3 years, 11 months ago
This essay explores the use of *A Colony in Crisis: The Saint-Domingue Grain Crisis of 1789* in the French literature classroom and how it helps address gaps in digital humanities and French language pedagogy while interrogating the colonial positionality of the French Revolution's digital archive. In 2015, the Newberry Library received a Digitizing Hidden Special Collections and Archives grant from the Council on Library and Information Resources (CLIR) to digitize 30,000 French language pamphlets, a portion of which pertains to the period before, during, and after the French Revolution. As the digital archive of the French Revolution rapidly grows, the need to draw attention to the broader context of revolution in the French Empire–particularly in the Caribbean–has become even more urgent. One of the most effective ways of addressing the marginalization of the Caribbean in colonial archives is through pedagogical interventions and course design. While digital humanities pedagogy has become somewhat normalized in the anglophone literature classroom, the French language classroom has been slow to adapt to the use of digital tools and pedagogy beyond the introductory language course.

PUNE: Researchers from several institutes, including the Agharkar Research Institute here, have rediscovered a rare endangered plant species,'spiderwort', after a gap of 161 years. They stumbled upon the rare plant species during a study to assess the floristic diversity of Chandoli national park in the northern Western Ghats of Maharashtra, which was recently declared a world heritage site by Unesco.
After its collection in 1851 from Parva Ghat in the state, the species was not found anywhere else in the state and was considered extinct.
The discovery, which has been published as a research paper in the Journal of Threatened Taxa, was made jointly by Shrinath Kavade, professor, Art, Commerce and Science College, Lanja in Ratnagiri; Subhash Deokule, University of Pune; P Lakshminarasimhan, Botanical Survey of India, Howrah; Prakash Diwekar, Botanical Survey of India, Western Regional Centre, Pune; and Sachin Punekar of Agharkar Research Institute. Punekar is attached to the city-based non-governmental organization, Biosphere.
Kavade said, "The species is called Belosynapsis vivipara, which was found along the backwaters of Warana river across Sahyadri range. The genus Belosynapsis is represented by five species distributed from South Asia to New Guinea. In India, however, it is represented by three species, namely, B epiphytica, B kewensis and B vivipara."
Punekar said, "The specimens found in 1851 were from Parva Ghat, which lies at the junction of Maharashtra, Goa and Karnataka, while the latest discovery was in the northern-most extension of the northern Western Ghats of Maharashtra. The distance between the two points is sizable and a thorough study of the area lying in between could further lead to similar discoveries, which will go a long way in conserving this threatened plant species."
The recent study found about 100 such plants growing on large tree trunks in the riparian forest patches of Male and Patharpunj villages in Chandoli national park, which forms the northern-most distribution of this vulnerable species. The plants usually grow at a higher elevation, on densely moss covered tree trunks and branches of trees in shady, semi-evergreen riparian forests.
"This species is on the verge of extinction and is equally important to biodiversity. Thus, before declaring any area as protected, certain species of the flora and fauna should be given due importance. Also, total protection should be given to the riparian forest areas of Chandoli national park for conservation of this vulnerable and endemic species. Ex-situ conservation and domestication of the species in greenhouses and gardens for future survival, besides its re-introduction in wild and similar habitats is imperative," Punekar said.

The Link Between Manly Traits And Male Fertility

The Link Between Manly Traits And Male Fertility
The Link Between Manly Traits And Male Fertility
According to the results of a new study, women tend to get more attracted to fertile males at the time of their ovulation to enhance their chances of successful conception. One must understand the theory of survival of the fittest to understand this concept. Traditionally, high testosterone levels are associated with more manly features and superior semen quality (or fertility). The idea is derived from prior researches in which it was identified that manly traits such as strong built, broad shoulders etc. are linked to high testosterone levels and genetic proficiency.
High Testosterone Levels and Manly Characteristics:
There are several parameters that help women in identifying fertile men; such as:
1. Masculine Built:
Men with high testosterone levels have strong bones and higher muscle mass due to anabolic activity of testosterone. This explains why masculine characteristics such as facial construction, built and other physical features are found to be more appealing to women in a heterosexual relation, especially at the time of their ovulation.
According to a new study reported in the PloS One (2) investigators suggested that high testosterone levels in men are associated with higher handgrip strength (HGS) scores. Based on the results obtained from Tanzanian population, it was identified that males with higher HGS have high serum testosterone levels and superior quality sperms, which makes them more likely to impregnate their partner in case of a successful sexual encounter.
2. Body Hair:
Former studies have shown that women are more allured towards men who are bigger and have more hairs. Even in animal kingdom, having more hair is considered as a sign of masculinity and hairy males tend to attract their companioTestosterone Levels Imagen towards them. For example male peacock's tail feathers are sign of their machismo.
To test this hypothesis, investigators conducted a study to see if women are attracted to hairy men or clean-shaved men. To obtain consistent and non-biased results, investigators used 15 male faces that were modified by a computer software to obtain five looks (such as clean shaved, light beard, light stubble and heavy stubble).
Based on the results of the data obtained from 60 women, it was discovered that women are most attracted to men with light beard, followed by men with stubble. The results of the study were reported in the peer reviewed journal Personality and Individual Differences (3).
3. Body Odor:
Besides facial features and body hair, certain other characteristics (such as sweat odor) can also have a huge impact on the women at the time of ovulation. High testosterone levels are associated with bigger sweat glands and ducts (and higher secretion of sweat) due to increased basal metabolism. At the time of ovulation, hormonal fluctuations tend to influence the mood, behavior and bodily responses to sexual stimuli. According to a new study reported in the Evolution and Human Behavior journal (4), the sense of smell and taste heightens in the fertile women during ovulation. This greatly improves the chances of men who secretes pheromones (or male scent in sweat).
4. Male Voice:
As crazy as it may sound, scientists actually decided to investigate the possible link between male's voice and sperm count. In order to test the theory to explore if sexy deep voices are associated with the quality of semen, scientists asked few young men to get their voice recorded and also collected their semen samples. Later on, the quality of sperms from the collected semen sample were examined and the recorded voices were played in front of few women. Researchers asked the women to rate those voices on the basis of sex appeal and attraction. As per researcher's expectations, the deeper voices were perceived as more captivating, but surprisingly, the attractive and muscular voice pitch does not found to be very strong associated with the quality of semen.
In short, manly traits may or may not be associated with high testosterone levels, but is very strongly linked to fertility in men.

The Blackbird is a large jet used by the X-Men for transport.
The Blackbird is a large jet that has been modified by Professor X so that he could easily transport his X-Men to missions. He keeps it in a large hanger under the Xavier Mansion. Cyclops is usually the pilot.
All of the X-Men then left in the blackbird to Asteroid M. Kitty Pryde snuck aboard as she did not want to be left behind. When they arrived the X-Men, minus Xavier, left in space suits to board the asteroid. Xavier realized that Kitty was there and asked her to come out. She had her own space suit on and phased through the hull to go to the asteroid.
The X-Men were successful in their mission. Unfortunately, Nightcrawler must have stayed aboard the asteroid or else the Earth would have been destroyed. Fortunately Xavier formulated a plan. All of the X-Men headed back towards the Blackbird. Xavier kept the Blackbird on a viewscreen that Nightcrawler could see. Xavier told him that he must teleport aboard at the very last second. Unfortunately Nightcrawler waited too long and the comet hits the asteroid.
Luckily Nightcrawler did teleport away but into the vacuum of space. But he was entering the atmosphere and would have burnt up. The X-Men hurried to get the grappling beam on him. Nightcrawler disappeared just before the beams could latch onto him. They heard a banging noise from the back and went to investigate to find Nightcrawler alive and well.
Kitty thanked Nightcrawler for his heroism. Storm asked Wolverine if he was wrong. He says that Kitty is still no X-Man. Not yet anyways.
It has a large space inside that can hold a number of people. It has lockers in the back to house several sizes of space suits.
The jet is able to fly in atmosphere and in space under its own power.
It can listen to radio and television broadcasts from around Earth even far beyond the moon.
It also has grappling beams that can latch onto an object and pull it in.
This Blackbird appears to be a modified Lockheed SR-71 Blackbird.

how to make au jus without beef broth
Au Jus
Au jus is a term that means "with juice" of the meat. It is most commonly found in French cuisine. Au jus can be found in beef or any meat dishes that are prepared or served along with light gravy, or bouillon that is made from all the fluids dripped out of the meat when it is being cooked.
Au Jus is one of the natural ways to enhance the flavor of meat and sauces. It mainly enhances chicken dishes because the chicken has a light taste, or it can be used with veal and lamb as well. French cuisine prefers having Au Jus in most of their meat dishes.
How To Make Au Jus Without Beef Broth?
Recipe of Au Jus Without Beef Broth
Beef Au jus Gravy
This recipe is perfect for a French dip sandwich. The preparation time of this recipe is 5-minutes and the cooking time requires about 10-11minutes. The total time required in the recipe is 15 minutes. The recipe requires a few steps that are mentioned below.
 1. First of all, you must take a saucepan and boil beef stock (not in the beef broth) in the pan.
 2. You must maintain the heat of the pan to medium-low and whisk the beef base.
 3. Add in Worcestershire sauce along with garlic, salt, and pepper.
 4. To make a thick gravy, add corn starch.
 5. Your beef Au jus gravy without beef broth is all ready to be served.
Substitute of Beef Broth
It's okay if you don't want to use beef broth! There are various substitutes for it. A lot of your favorite recipes are using beef broth, however, you need substitutes that can work well in all your daily recipes. We have mentioned below a few substitutes for beef broth.
1. Beef Stock
If using beef is not a problem for you then you can switch between beef broth and beef stock. Both of these ingredients taste almost the same, however, the difference is majorly in the extracting materials. The difference between beef-broth and beef-stock is, beef broth is made from an extract that is taken out of both meat and bones attached to that meat.
While the beef stock is made with vegetables and beef bones. Most people, in case of running out of beef broth, use beef stock because it is the best replacement for beef broth in any recipe.
2. Bouillon Cubes
Bouillon cubes are also beef extracts but in a different state. Beef broth exists in a liquid form and bouillon cubes are found as a dried extract in cubes form. You can use bouillon cubes by dissolving them in cups of water, and it can replace a cup of beef broth in any recipe if one cube is dissolved in one cup of water.
These cubes of beef bouillon are concentrated to give an enhanced taste when they are dissolved in water.
However, if you are trying to maintain a pure vegan meal, then you can use Vegetable Broth, which tastes a little bit different however it's a great vegan replacement for beef broth.
Hopefully, this blog helped you in making an Au Jus recipe without the use of beef broth.

Let$\:$ $T=\{\varphi \in \Pi_1: PA+Con(PA) \vdash \varphi\:\:and\:\: PA\nvdash \varphi \}$. $\:$By the facts presented here Are undecidable consequences of Con recursively enumerable? by Andreas Blass and Emil Jerabek, we know that:
$(1)$ $T$ is $\Pi_1$-hard.
However it seems we can also prove that
$(2)$ $Cn(PA+Con(PA)) = Cn(PA+T)$
Let $\varphi$ be such that $PA+Con(PA) \models \varphi$. Obviously $Con(PA) \in T$, therefore trivially $PA+T \models \varphi$.
In the other direction, let $\varphi$ be such that $PA+T \models \varphi$. Since this is a first-order theory, by completeness and compactness we can infer that in the proof of $\varphi$ from $PA+T$ we use finitely many formulae, namely: $\phi_1, \phi_2, \dots \phi_n$. All of them either belong to $PA$ or belong to $T$ or can be inferred from $PA+T$. In particular they are implied by $PA+Con(PA)$. If so, they can be used in the proof of $\varphi$ form $PA+Con(PA)$, so $PA+Con(PA) \models \varphi$.
But from the work of Jeroslow _URL_ (Corollary 4) we find out that:
$(3)$ $Cn(PA+\{\varphi \in \Pi_1: \mathbb{N} \models \varphi \})$ is not $\Delta_2$
Since $(1)$ and due to the fact that the set above (I mean: $\Pi_1 \cap Th(\mathbb{N})$) has got its own truth definition and is $\Pi_1$ we infer that it is reducible to $T$.
So it seems that $Cn(PA+T)$ should also be "hard" and "not learnable" (in the sense of not being $\Delta_2$ ).
However we also know that $Cn(PA+Con(PA))$ is $\Sigma_1$. Since $(2)$ however $Cn(PA+T)$ is the same set of formulae.
So my question is: did I make any mistake in the reasoning above and one of $(1)$, $(2)$, $(3)$ is false or it can be the case that when we close some "hard" set up logical consequence, we can get an "easier" set. If so, the question is: how come?
share|improve this question
I don't see any mistakes. A good chunk of the complexity of T comes from excluding certain sentences; specifically, those sentences provable in PA. But adding PA and then closing under consequence restores those sentences. That's why the complexity decreases. – Dan Turetsky Jun 5 '13 at 23:48
Thanks. You're right, but let's look at the theory I mentioned: PA+(Set of true Pi_1-sentences) which closed under consequence gives us nonlearnable theory. I don't "see", how - having a computable reduction of Set of true Pi_1-sentences to the set T- we obtain theories with different complexities? – mtg Jun 6 '13 at 0:15

The $\Pi_1$-hardness of $T$ comes from the clause $PA\not\vdash\varphi$. But when you consider $Cn(PA+T)$ its influence vanishes.
As $$T\subset Cn(PA+Con(PA))$$ we have $$Cn(PA+T)\subseteq Cn(PA+Cn(PA+Con(PA)))=Cn(PA+Con(PA)).$$ On the other hand $Con(PA)\in T$ therefore $Cn(PA+Con(PA))\subseteq Cn(PA+T)$.
Thus we have the equality $Cn(PA+T) = Cn(PA+Con(PA))$ indeed.
This also does not contradict Jeroslow's results as in $PA+\Pi_1(\mathbb{N})$ there are all $Con(X)$ (not just $Con(PA)$) and which is a sourse of complexity of this theory.
It is not very suprising that Cn operator can decrease the complexity of a set of sentences - you can always add a negation of a sentence of any given set to obtain an inconsistent theory i.e. primitive recursive. But it is a nice example how it can decrease it to something higher than just PR.

Selenium animal remedies should be recommended, authorised or dispensed according to established need and veterinarians should properly, and within reason, manage the risks associated with authorising/dispensing such products
Selenium is an essential trace element but can be toxic if used in excess. The therapeutic index for selenised animal remedies is low and there are risks associated with the use of these products. There is a range of selenium supplementation options and products available and poisoning associated with the use of selenium products will always have the potential to occur.
Pure selenium compounds (i.e. those containing selenium above a specific concentration) are only available from veterinarians.
- Veterinarians should make every effort to ensure clients understand the selenium requirements of their livestock and options for meeting them, so that clients can make informed decisions.
- Veterinarians need to be aware of the ACVM requirements regarding compounding, and should be aware of selenium supplementation product options that are available.
- Veterinarians should have sufficient knowledge of the natural soil selenium levels and the type of pasture/forage on clients' farms to assist making informed recommendations on supplementation.
- Appropriate laboratory tests (e.g. liver and blood samples) to ascertain the status of a farm and its animals should be undertaken to monitor effectiveness of supplementation.
- Veterinarians should advise that the concurrent use of other selenised products may be hazardous and may cause poisoning (e.g. if selenium is also added in fertiliser).
- If selenium is added, veterinarians should ensure correct addition rates and ensure correct advice is given for mixing and for use. This should be in writing.
- The selenium status of the property and of any animals, and any dispensing of selenium products should be recorded for each client's property.

Did San Luis Obispo produce any goods? Were they well-known for producing anything?
Did San Luis Obispo produce any goods? Were they well-known for producing anything? I'm working on a Mission report and I can't find any literature on
The primary products produced by the missions were cow hides and tallow. The cow hides were also known as Yankee dollars, because they were traded for manufactured goods brought by ships which were mostly from Boston. San Luis Obispo was also famous for being the first mission to make roofing tiles, which the other missions soon copied.
As of 1832, the last year for which records were kept, San Luis Obispo had a herd of 2.500 cattle and 5,432 sheep. San Luis Obispo also had large agricultural fields under cultivation.

Based on available archaeological, written and iconographic sources, the article gives a picture of Germanic infants and juveniles. Here are analysed the Germanic burials of children and immature individuals in the mid-Danubian region from the 1st to 4th cent. BC. The territory under study comprises southwest Slovakia, Moravia and Lower Austria. Graves with anthropological classification of skeletal remains - infants, juveniles or individuals at the turn of infants/juveniles were included into the analyses. The territory under study provided us with 120 graves of infants and juveniles, 115 of them were cremation and 5 inhumation burials. In one case a common grave of a child and juvenile was excavated, in three other cases children were buried with adult individuals. Graves from settlements are presented in the article as well and grave goods are comparable with those from graves situated on necropolises. Grave equipment is confronted with age of deceased children, their evolutionary stage and specificities. Special attention is paid to clothing fittings, occurrence of weapons and artefacts of everyday use in children's burials. Cases, when an individual of juvenile or juvenile/adult age could be a parent, i.e. could have own children, can occur among the juvenile burials.

Climate Change and the Historical Imagination
- Lawrence A. Kimpton Distinguished Service Professor in History, South Asian Languages, and Civilizations, University of Chicago
In this talk, historian Dipesh Chakrabarty will suggest that man-made global warming spells the collapse of the age-old humanist distinction between natural history and human history. He will ask us to contemplate how our planetary crisis qualifies our sense of human universals while challenging our capacity for historical understanding.
Chakrabarty obtained his Ph.D. in History from the Australian National University, Canberra, Australia in 1984. He holds honorary degrees from the University of London and the University of Antwerp. His current research focuses on anthropogenic climate change and its implications for historical thinking, on the history of the idea of historical truth, and on historical genealogies of crowd-politics in India.

Estimate Your Blood Alcohol Content with Wolfram Alpha
Wolfram Alpha is the place to go to do all kinds of calculations, you can even use it to estimate your blood alcohol level after you've put away a few drinks.
Note that this will only be an estimate, since it ignores variations in metabolism, food intake, medication, and so on. As always, we don't recommend you use this to judge whether you can drive—it'll never be accurate enough to judge whether you're legal, and no matter how well you may think you handle your liquor, don't drink and drive.
All that out of the way, it's a pretty interesting little tool. Here's what you do:
 1. Go to Wolfram Alpha.
 2. In the search box, input the following: BAC 5 drinks, 3 hours, male, 180lb (change the number of drinks, the period of time you spent drinking, your gender, and your weight.)
 3. Click the = button or press Enter on your keyboard. The results will be displayed.
It'll show you what your blood alcohol percentage is, and even show you a graph of (roughly) how long it'll take to get back down to 0%. Again, it's not perfect—and it shouldn't judge whether you're sober enough to drive—but it is pretty cool.

, Rosdiana (1997) A Morphological study of Malang reversion usage. Bachelor thesis, Petra Christian University.Full text not available from this repository.
Malang Walikan is a kind of language that uses reversed words in which Malang people use in their daily-conversation, especially in informal talks. Usually it is the younger generations who use such language more often than the older ones. There are three reasons why the writer is interested in analyzing Malang reversion. The first reason is because she has many friends who live in Malang and use the reversion everyday. The second is she is curious about the usage of Malang reversion. She becomes more interested in such reversion after she read a thesis of Malang reversion done by former student of IKIP Malang in 1976. This study tries to find out the various types of Malang Walikan. Another important focus of this study is to determine the source languages of Malang Walikan. This study is also a kind of further study of similar research conducted by Melik Sumanandar. The reason is to find out the proves of the writer's disagreement to Sumanandar's findings. After a thorough analysis, it is revealed that Malang Walikan can be divided into three types of words; Systematic reversion, Fluctuated reversion, and Slang. There is a particular formula to form systematic reversion, while the other two types could not be found any formula. The formula is: p l + P 2 +..... + p x becomes Px +P(x-1)+......+P1 The words of Systematic and Fluctuated reversions are derived from Indonesian and Javanese since the people of Malang are influenced by the usage of both languages. Thus, the domination of Indonesian words can be seen obviously in both types of reversion.

Have You Tried: Associative Dimensions
Ever wonder why some dimensions update when the geometry changes and others don't? Dimensions that update are linked or associated with the geometry they measure. That's called dimension associativity. Dimensions can be associative or non-associative depending on how they are created. They can also become disassociated if the geometry they measure are deleted or exploded.
When a dimension becomes dissociated, AutoCAD informs with one of the following messages at the Command prompt:
 - Dimension disassociated
 - Dimension extension disassociated
Note: The video doesn't contain audio or closed captions.
In this Have You Tried, we'll cover how to turn on the annotation monitor to indicate disassociated dimensions and what to look for when the design changes.
We'll also learn how to reassociate, disassociate, and delete dimensions when they are no longer needed.
For example, the yellow badges indicate this drawing has two dimensions that are not associated with the geometry they measure.
Types of Dimension Associativity
Associating dimensions to drawing geometry makes it more efficient to update the dimensions when the design changes.
There are three types of dimension associativity:
 - Associative dimensions automatically adjust their locations, orientations, and measurement values when the geometry associated with them is modified.
 - Non-associative dimensions can be selected and modified using grips, but they don't change automatically when the geometry they measure is modified.
 - Partially associative dimensions exist when only one extension line is associated with a geometric object. This typically occurs when geometry associated with a dimension is deleted or exploded.

Annotation Monitor
The annotation monitor, when active, displays a yellow badge on the dimensions that have lost associativity. Common causes for losing associativity is when geometry has been deleted or significantly modified; not necessarily when geometry has been simply moved or resized.
To Turn the Annotation Monitor On and Off
Click the Annotation Monitor status bar button to turn the annotation monitor on and off .
When the annotation monitor is active, the Annotation Monitor icon is added to the status bar.
If you don't see the Annotation Monitor status bar button, click Customization , located at the far-right end of the status bar, and select Annotation Monitor.
When the annotation monitor is off, there's no visual indicator that displays if a dimension is associative or non-associative. You can use the Properties palette or LIST command to verify the status of a dimension.
Control Whether New Dimensions are Associative
By default, all new dimensions are associative. This can be changed in the Options dialog box.
 1. Click Application menu > Options
 2. In the Options dialog box, User Preferences tab, under Associative Dimensioning, verify that Make New Dimensions Associative is checked.
 3. Click OK.
Note: You can also change associative dimensioning by typing
DIMASSOC at the Command prompt.
Associative dimensions support most types of geometry with the following exceptions:
 - Hatches
 - Images
 - Underlays
 - Multiline objects
 - 2D solids
Example of a Disassociated Dimension
Let's walk through an example of how a dimension can become disassociated.
Verify that the annotation monitor is on.
 1. Create a new drawing and add three circles and two dimensions like the example below.
 2. Try moving the middle circle to the left.
 See how the dimension values change. That's because the dimensions are associated to the centers of the three circles.
 3. Now erase the middle circle.
 A yellow badge is displayed on the dimensions indicating they are no longer associated to the circles. Deleting the middle circle created two disassociated dimensions.
Working with Disassociated Dimension
Due to a design change, we now have two disassociated dimensions. To fix this, we'll delete the dimension that's no longer needed and reassociate the other dimension to the remaining circles.
INTERESTING: AutoCAD Video Tips: Find a Home for Orphaned Xrefs (Lynn Allen/Cadalyst Magazine)
There are two ways to do this, one is from the ribbon and the other is clicking the yellow badge on the dimension. Both methods are similar. In the example below, let's click the yellow badge and use the menu.
 1. Click the yellow badge and choose Delete from the menu to remove this dimension that's no longer needed.
 2. Click the yellow badge on the remaining dimension and choose Reassociate from the menu.
 Use object snaps to accurately select the center of the circles to reassociate the dimension to the circles.
 Notice that the yellow badge is no longer displayed on the dimension. This indicates that the dimension is now associated with the centers of the two circles.
 3. Move the circle on the right.
 The dimension displays the new distance between the circles.
Associate or Reassociate a Dimension Using the Ribbon
With the annotation monitor active, let's associate some dimensions to geometry.
To make a dimension associative click
Annotate tab > Dimensions panel > Reassociate
 1. Select one or more dimensions to associate or reassociate.
 2. Press Enter and do one of the following:
 - To associate the dimension to specific geometry, enter s (Select object) and select the geometry.
 - To reassociate, select the reference point on an object, using object snaps as needed, to associate the indicated extension line.
 3. Repeat steps as needed.
Note: If a dimension has been exploded, it can no longer be reassociated to geometry.
To Disassociate a Dimension
 1. At the Command prompt, enter DIMDISASSOCIATE.
 2. Select one or more dimensions to disassociate and press Enter.
 3. When the annotation monitor is active, you'll see a yellow badge appear on the dimension indicating the dimension is non-associative.
Summary
Associated dimension can help keep your drawing dimensions updated when the design changes.

Imagine that you are a nutritionist trying to explore the nutritional content of food. What is the best way to differentiate food items? By vitamin content? Protein levels? Or perhaps a combination of both?
Knowing the variables that best differentiate your items has several uses:
1. Visualization. Using the right variables to plot items will give more insights.
2. Uncovering Clusters. With good visualizations, hidden categories or clusters could be identified. Among food items for instance, we may identify broad categories like meat and vegetables, as well as sub-categories such as types of vegetables.
The question is, how do we derive the variables that best differentiate items?
Principal Components Analysis (PCA) is a technique that finds underlying variables (known as principal components) that best differentiate your data points. Principal components are dimensions along which your data points are most spread out:
A principal component can be expressed by one or more existing variables. For example, we may use a single variable – vitamin C – to differentiate food items. Because vitamin C is present in vegetables but absent in meat, the resulting plot (below, left) will differentiate vegetables from meat, but meat items will clumped be together.
To spread the meat items out, we can use fat content in addition to vitamin C levels, since fat is present in meat but absent in vegetables. However, fat and vitamin C levels are measured in different units. To combine the two variables, we first have to normalize them, meaning to shift them onto a uniform standard scale, which would allow us to calculate a new variable – vitamin C minus fat. Combining the two variables helps to spread out both vegetable and meat items.
The spread can be further improved by adding fiber, of which vegetable items have varying levels. This new variable – (vitamin C + fiber) minus fat – achieves the best data spread yet.
While in this demonstration we tried to derive principal components by trial-and-error, PCA does this by systematic computation.
Using data from the United States Department of Agriculture, we analyzed the nutritional content of a random sample of food items. Four nutrition variables were analyzed: Vitamin C, Fiber, Fat and Protein. For fair comparison, food items were raw and measured by 100g.
Among food items, the presence of certain nutrients appear correlated. This is illustrated in the barplot below with 4 example items:
Specifically, fat and protein levels seem to move in the same direction with each other, and in the opposite direction from fiber and vitamin C levels. To confirm our hypothesis, we can check for correlations (tutorial: correlation analysis) between the nutrition variables. As expected, there are large positive correlations between fat and protein levels (r = 0.56), as well as between fiber and vitamin C levels (r = 0.57).
Therefore, instead of analyzing all 4 nutrition variables, we can combine highly-correlated variables, leaving just 2 dimensions to consider. This is the same strategy used in PCA – it examines correlations between variables to reduce the number of dimensions in the dataset. This is why PCA is called a dimension reduction technique.
Applying PCA to this food dataset results in the following principal components:
The numbers represent weights used in combining variables to derive principal components. For example, to get the top principal component (PC1) value for a particular food item, we add up the amount of Fiber and Vitamin C it contains, with slightly more emphasis on Fiber, and then from that we subtract the amount of Fat and Protein it contains, with Protein negated to a larger extent.
We observe that the top principal component (PC1) summarizes our findings so far – it has paired fat with protein, and fiber with vitamin C. It also takes into account the inverse relationship between the pairs. Hence, PC1 likely serves to differentiate meat from vegetables. The second principal component (PC2) is a combination of two unrelated nutrition variables – fat and vitamin C. It serves to further differentiate sub-categories within meat (using fat) and vegetables (using vitamin C).
Using the top 2 principal components to plot food items results in the best data spread thus far:
Meat items (blue) have low PC1 values, and are thus concentrated on the left of the plot, on the opposite side from vegetable items (orange). Among meats, seafood items (dark blue) have lower fat content, so they have lower PC2 values and are at the bottom of the plot. Several non-leafy vegetarian items (dark orange), having lower vitamin C content, also have lower PC2 values and appear at the bottom.
Choosing the Number of Components. As principal components are derived from existing variables, the information available to differentiate data points is constrained by the number of variables you start with. Hence, the above PCA on food items only generated 4 principal components, corresponding to the original number of variables in the dataset.
Principal components are also ordered by their effectiveness in differentiating data points, with the first principal component doing so to the largest degree. To keep results simple and generalizable, only the first few principal components are selected for visualization and further analysis. The number of principal components to consider is determined by something called a scree plot:
A scree plot shows the decreasing effectiveness of subsequent principal components in differentiating data points. A rule of thumb is to use the number of principal components corresponding to the location of a kink. In the plot above, the kink is located at the second component. This means that even though having three or more principal components would better differentiate data points, this extra information may not justify the resulting complexity of the solution. As we can see from the scree plot, the top 2 principal components already account for about 70% of data spread. Using fewer principal components to explain the current data sample better ensures that the same components can be generalized to another data sample.
Maximizing Spread. The main assumption of PCA is that dimensions that reveal the largest spread among data points are the most useful. However, this may not be true. A popular counter example is the task of counting pancakes arranged in a stack, with pancake mass representing data points:
To count the number of pancakes, one pancake is differentiated from the next along the vertical axis (i.e. height of the stack). However, if the stack is short, PCA would erroneously identify a horizontal axis (i.e. diameter of the pancakes) as a useful principal component for our task, as it would be the dimension along which there is largest spread.
Interpreting Components. If we are able to interpret the principal components of the pancake stack, with intelligible labels such as "height of stack" or "diameter of pancakes", we might be able to select the correct principal components for analysis. However, this is often not the case. Interpretations of generated components have to be inferred, and sometimes we may struggle to explain the combination of variables in a principal component.
Nonetheless, having prior domain knowledge could help. In our example with food items, prior knowledge of major food categories help us to comprehend why nutrition variables are combined the way they are to form principal components.
Orthogonal Components. One major drawback of PCA is that the principal components it generates must not overlap in space, otherwise known as orthogonal components. This means that the components are always positioned at 90 degrees to each other. However, this assumption is restrictive as informative dimensions may not necessarily be orthogonal to each other:
To resolve this, we can use an alternative technique called Independent Component Analysis (ICA).
ICA allows its components to overlap in space, thus they do not need to be orthogonal. Instead, ICA forbids its components to overlap in the information they contain, aiming to reduce mutual information shared between components. Hence, ICA's components are independent, with each component revealing unique information on the data set.
Information has thus far been represented by the degree of data spread, with dimensions along which data is more spread out being more informative. This is may not always be true, as seen from the pancake example. However, ICA is able to overcome this by taking into account other sources of information apart from data spread.
Therefore, ICA may be a backup technique to use if we suspect that components need to be derived based on information beyond data spread, or that components may not be orthogonal.
PCA is a classic technique to derive underlying variables, reducing the number of dimensions we need to consider in a dataset. In our example above, we were able to visualize the food dataset in a 2-dimensional graph, even though it originally had 4 variables. However, PCA makes several assumptions, such as relying on data spread and orthogonality to derive components. On the other hand, ICA is not subjected to these assumptions. Therefore, when in doubt, one could consider running a ICA to verify and complement results from a PCA.

Decision Matrix
Event handling and Rules
Every event on a VSCP segment can be seen as an event. To be of any use to anyone a decision has to be taken on what to do as a result of the event. This is done in a decision matrix, which is a standardized way to write the rules that take care of events. To get something done when a specific event is detected some sort of action mechanism is needed.
The event-decision-action model or eda-model is the way we look at the functionality of a VSCP-node. First of all a node can be a level I or level II node. A level I node can perform actions from all level I events. A level II node can handle both level I and level II events. In fact when we define rules we define them at the highest level.
The model
To be able to build a software model that is common for several device/machine/situation types and environments we have to make a model to suit the typical control situation. The model is very simple and is also very easy to implement on different target environments.
Event
Something happens that triggers some kind of input. This could be the elapse of a timer, a delivered temperature reading, a triggered fire alarm etc. Without this state there is nothing to do. We call this state the EVENT - state.
Decision
If an event occurs we may react in some way to this happening. This reaction comes after a decision about if and how the event should be handled. We use a decision matrix to control the logic of our decisions. Every element in the decision matrix handles one event and performs one action. A decision matrix element is also capable of generating events and can in this way perform several actions on the behalf of one event.
Action
The action is the function, thread, procedure, method or other functionality that should be carried out as a result of an event.
The states represented by EVENT + DECISION + ACTION are treated as one transaction. All steps must be handled for the transaction to be marked as completed.
So when you describe the functionality of a VSCP-node you say
 - This node reacts on the following events.
 - This node can perform the following actions.
To make the node a useful piece of equipment it needs a decision matrix. This matrix can be implemented with no possibility for a user to change it or it can be undefined and left for the user to specify.
Decision matrix for Level I nodes.
In resource-limited environments, such as a microprocessor, the previously discussed matrix format takes up to much space and a more resource friendly format is therefore defined. Here the class + type bytes formats the event.
This matrix has no trigger for data values. This has to be done internally by the application using user defined codes.
A matrix row consists of 8 bytes and has the following format
Level I decision matrix
Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7
oaddr flags class-mask class-filter type-mask type-filter action action-parameter
oaddr
oaddr is the originating node nickname. We are only interested in events from the specific node given by oaddr if bit 6 of flags is set. For example we may be interested in events only from node 0x00, a segment controller, or 0xFF, a node without a nickname. If bit 6 of flags is not set, oaddr will not be checked and events from all nodes will be accepted iof all other criteria match.
flag
Bit # Description
7 Row is enabled if set to 1
6 oaddr should match nickname of event (=1) or don't care (=0)
5 Indicates (if set to 1) that the originating address should be hard-coded
4 Match Zone to trigger DM entry if set to 1
3 Match sub-zone to trigger DM entry if set to 1.
2 Reserved
1 Class-mask bit 8
0 Class-filter bit 8
The enable bit can be used to disable a decision matrix row while it is edited.
The zone and use sub-zone bits can be activated to have a check on the zone/sub-zone information of an event. That is the zone/sub-zone of the machine must match the one of the event to trigger the DM row. Bits 0/1 are the ninth bit of the filter/mask not enable bits.
class-mask / class-filter
A class that should trigger this decision matrix row is defined in class-mask and class-filter with bit eight for both taken from the flags byte.
The following table illustrates how this works
Truth table for filter/mask
Mask bit n Filter bit n Incoming event class bit n Accept or reject bit n
0 x x Accept
1 0 0 Accept
1 0 1 Reject
1 1 0 Reject
1 1 1 Accept
Think of the mask as having ones at positions that are of interest and the filter telling what the value should be for those bit positions that are of interest.
 - So to only accept one class set all mask bits to one and enter the class in filter.
 - To accept all classes set the mask to 0. In this case filter don't care.
type-mask / type-filter
A type that should trigger this decision matrix row is defined in type-mask and type-filter with bit eight for both taken from the flags byte.
A similar truth table as for the class-mask/filter is used.
action
This is the action or operation that should be performed if the filtering is satisfied. Only action code 0x00 is predefined and means No-Operation. All other codes are application specific and typical application defined codes could do measurement, send predefined event etc.
action-parameter
A numeric action can be set and its meaning is application specific.
General
The number of matrix rows are limited in a micro controller. The control class has an event defined that gets the number of elements in the matrix and the location of the matrix in the register model of the node (Get Decision matrix info, CLASS1.PROTOCOL, Type=33).
The matrix information is read and written with the standard read/write control functions. And is placed in the standard low register range (<0x80) or in an optional page in this area.
Note that there is no demand that a node implements a decision matrix. If not implemented the Get Decision matrix info just returns a zero size.
A special paged feature is available for the decision matrix to save register space. If the offset for the decision matrix is 0x7e the decision matrix is indexed. This means that 0x7e is the index and 0x7f is the data. Read a byte from the matrix by first setting the index to the position you want to read and reading the byte in 0x7f. Set index to the position you want to write and write data into 0x7f.
Method CLASS1.PROTOCOL TYPE=32 is used to fetch decision matrix information for a specific node.
It is important to note that the decision matrix can contain any number of lines for a specific event element. So one incoming event can trigger many actions.
Events are marked as handled when the action thread is started. This can be bad in some situations where the event chain is dependent on the action to complete its task before any new work is done. In this case it is better to continue the event chain by posting an event from the action thread instead of setting the following event as a next event in the decision matrix.
The decision matrix structure gives us the freedom to implement events that perform:
 - Exactly one action.
 - Several actions.
 - Several actions in a sequence.
Decision matrix for Level II nodes.
There is a lot more freedom to set up a decision matrix structures on level II nodes due to less space constraints.One implementation is the decision matrix in the VSCP Daemon which is described here.
A general form is discussed here. To understand how this decision matrix is updated one needs to understand how it is set up. Each line of the matrix is built from a table of entries of the following form:
byte 0-3 byte 4-7 byte 8-11 byte 12-13 byte 14-n
mask filter control action action-parameter
where the action-parameter has device specific length.
Mask (32-bit)
This is a bit mask, which has ones at the bit positions of the event that is interesting. So 0xFFFFFFFF makes all events interesting. Class is in the high word. Type is in the low word. For a truth table see the class-mask for Level I decision matrices.
Filter (32-bit)
This is a bit mask, which tells the value for bits that is of interest. Class is in the high word. Type is in the low word. For a truth table see the class-mask for Level I decision matrices.

Short cycle times for the assembly are extremely important in automobile production. In order to design the optimum ergonomics for the worker, the vehicles are transported along the production line on lift tables. Depending on the work operation to be performed, the vehicles are moved to the optimum height in order to ensure as efficient working as possible. Which exact height has been reached is established using draw-wire sensors from Micro-Epsilon. Completely integrated in the lift table, they ensure more reliability and higher productivity.

From Wikipedia, the free encyclopedia
Phononic stop bands are formed for materials with periodic elastic properties. The material does not need to be a crystal.
The basis of phononic crystals dates back to Newton who imagined that sound waves propagated through air in the same way that an elastic wave would propagate along a lattice of point masses connected by springs with an elastic force constant E. This force constant is identical to the modulus of the material. Of course with phononic crystals of materials with differing modulus the calculations are a little more complicated than this simple model.
Based on Newton's observation we can conclude that a key factor for acoustic band-gap engineering is impedance mismatch between periodic elements comprising the crystal and the surrounding medium. When an advancing wave-front meets a material with very high impedance it will tend to increase its phase velocity through that medium. Likewise, when the advancing wave-front meets a low impedance medium it will slow down. We can exploit this concept with periodic (and handcrafted) arrangements of impedance mismatched elements to affect acoustic waves in the crystal – essentially band-gap engineering.
The position of the band-gap in frequency space for a phononic crystal is controlled by the size and arrangement of the elements comprising the crystal. The width of the band gap is generally related to the difference in the speed of sound (due to impedance differences) through the materials that comprise the composite.

If there is no common sub-class among these element types, you can use LINQ to project the lists using a generic Tuple<int, int, object> (i.e. rating, vote, and the original element instance) containing the two properties you are interested in. Then you can do a simple query to pick the top 10 elements:
List<A> ax = /* ... */;
List<B> bx = /* ... */;
List<C> cx = /* ... */;
/* ... */
IEnumerable<Tuple<int, int, object>> ratingsAndVotes =
 ax.Select((a) => Tuple.Create(a.Rating, a.Vote, a)).Concat(
 bx.Select((b) => Tuple.Create(b.Rating, b.Vote, b)).Concat(
 cx.Select((c) => Tuple.Create(c.Rating, c.Vote, c)) /* ... */;
Tuple<int, int, object>[] topTenItems =
 ratingsAndVotes.OrderByDescending((i) => i.Item1).ThenByDescending((i) => i.Item2).Take(10).ToArray();
// topTenItems now contains the top 10 items out of all the lists;
// for each tuple element, Item1 = rating, Item2 = vote,
// Item3 = original list item (as object)
score:8
Try something like below
var topTen = yourList.OrderBy(x => x.Rating).ThenBy(z => z.Vote).Take(10)
score:3
You can start with something like:
 var res = l1.Concat(l2).Concat(l3).Concat(l4).Concat(l5)
 .OrderByDescending(k => k.Rating)
 .ThenBy(k=>k.Vote)
 .Take(10).ToList();
where l1...l5 are your lists
score:1
You can use OrderBy and ThenBy to order by two (or more) fields and then use Take to get the top 10:
var myList = new List<Film>();
// ... populate list with some stuff
var top10 = myList.OrderBy(f => f.Rating).ThenBy(f => f.Vote).Take(10);
Hope that helps :)

an even numbered offset (so long as no other partitioner is used on the drive).
 - Using a 1-MiB alignment boundary allows safer editing of the partition table with Vista Disk Management.
Partition tables using a CHS geometry (or some mix of alignments) may prevent Vista from resizing partitions or it may produce unconventional partition tables. For example, the endings of the "EBR extended partitions" (type 05) may overlap other partitions, and it will leave unprecedented amounts of space between an extended boot record and its logical drive. Ranish Partition Manager does not show an error if there are more than 63 sectors between the EBR and its logical volume, so long as the EBRs and VBRs are on the first sector of any track (head). If either the VBR or the EBR are not on the first sector of a head, Ranish Partition Manager shows the "partition" in red and when the partition is highlighted, this error message appears: "Boot sector doesn't have valid information". Using the 1-MiB alignment boundary will not put VBRs or EBRs on the first sector of a track (according to any standard CHS geometry) and Vista Disk Management will not use the CHS geometry of a partition table created with a different partition editor.
 - A disk that is solely partitioned with Vista Disk Management can create partitions in exact MiB sizes and never leave leftover bits of space between partitions.
With Vista DM, all the logical drives besides the one nearest the beginning of the extended partition (type 0F), usually reserve exactly one additional MiB, for an extended boot record, instead of the 63 sectors (31.5 KiB) that is most commonly reserved according to alignments based on a CHS geometry. If other partition editors are used on the disk then Vista DM may reserve different amounts of space for the EBRs.
Threatening Usage
General recommendation to work on drives and partitions only after prior backing up should be strongly obeyed.
Delete partition
The function delete partition works without any prior confirmation on impact for other partitions and may destroy other partitions without prior notice. This function is recommended to be ignored as far as no backup is available. Other vendors' solutions provide protection for other partitions.
Incorrectly displaying partition tables
Vista and Windows 7 Disk Management may incorrectly display logical drives as primary partitions, particularly when they are not labeled (or formatted?) as NTFS or FAT [1] (see section "You may see several primary partitions on a drive").

This issue occurs when a measure systematically overor underpredicts a criterion across demographic groups or is associated with the criterion unequally across the groups. We tested the differential validity of a widely used psychological test, the Minnesota Multiphasic Personality Inventory (MMPI)-2-Restructured Form (MMPI-2-RF), as a function of gender (male, female) and ethnicity (Caucasian, African American, and Hispanic/Latino American) in large samples of forensic psychiatric inpatients. Regression models were estimated in a multigroup framework. The analyses yielded negligible to small statistical evidence of differential validity in MMPI-2-RF scores predicting the number of future suicidal behaviors and violent behaviors in the samples. This evidence supports use of the MMPI-2-RF as a generally unbiased instrument for predicting key criteria across genders and ethnicities in a forensic psychiatric population.

Preferences, Practices, and Virtues: An Ethical Reflection on the Universal Apostolic Preferences
The Society of Jesus has promulgated the Universal Apostolic Preferences (UAPs) for the decade 2019-29. We know what the UAPs are: to seek God, walk with the poor, accompany youth, and collaborate in the care of the earth. And we know what they are for: the ongoing conversion of persons and institutions in their commitment to the mission of reconciliation of justice. But what, exactly, is a "preference" anyhow? In this reflection, I draw on the moral tradition of virtue ethics to argue that the preferences are best understood as "practices" or, in other words, as the fundamental actions by which crucial virtues like mercy and justice are developed in persons and in institutions. I also argue that seeing the preferences as practices in the context of virtue ethics opens up fruitful possibilities for fostering engagement with the UAPs at Jesuit institutions of higher education.

Naming steps
Occasionally you'll be confronted with the task of naming a step. It's important that this name is informative as it will appear within the UI. Other than that, there are only two rules:
 1. Do not use the "." character in step names. Currently that is used for indicating step nesting in the UI, but should hopefully change in the future.
 2. Step names must be unique within a single execution of a recipe. The reason for this is because recipe engine relies on unique step names for mocking out step data when testing. For this reason, step names will then be extended with a number such as "(3)" which generally isn't very useful to a reader. This is also subject to change in the future.


The antibacterial properties of wood should be leveraged in construction
The antibacterial properties of wood should be leveraged in construction
- Many materials contain volatile organic compounds, also known as VOCs, which are considered to be health hazards. Wood's volatile compounds have been found to have some antibacterial effect. According to studies however, the scent from many wood compounds is harmful to bacteria but not humans, says Tiina Vainio-Kaila.
Vainio-Kaila, who received her doctorate on the subject, has compared how well bacteria survive on untreated wood surfaces when compared to glass, which is traditionally considered hygienic. - When the amounts of bacterial growth on different surfaces were cultured and compared in a laboratory, both e. coli and listeria bacteria gradually died on the wood surface, but survived on the glass plate serving as a control.
- Wood extracts have also been found to be reasonably effective against hospital bacteria. It can be said that wood surfaces and many wood compounds have antibacterial properties and that pine has a slightly larger antibacterial effect than spruce. Many of the dozens of different wood extracts have been found to have antibacterial properties as the lignin that binds the fibres together has an antibacterial effect. In addition, wood surfaces dry quickly; this dryness puts bacteria at a disadvantage.
Vainio-Kaila points out that there has been very little research in general into the effects of wood on well-being. For example, surveys of residents conducted in wooden apartment buildings indicate that the scent of wood is not considered unpleasant and that a wooden building does not cause allergies in residents in the same way many other materials do.
According to Vainio-Kaila, the underlying antibacterial qualities of wood do not come from a single substance but are the result of a well-functioning whole of many substances. - If a change of materials can slow down the spread of hospital bacteria, we should seize the opportunity. Now that antibacterial research on wood has begun, it would be a good idea to properly study the effects of antibacterial wood in hospital and day-care building materials.
There are already some practical applications that leverage wood's antibacterial properties. - For example, the German company Wilms HygieneHoltz manufactures a variety of hygiene products from wood, ranging from skin creams to anti-bacterial rugs and cutting boards. They have improved wood's inherent antibacterial properties in their products even more. Here at home, a Finnish company has launched a sap-based antibacterial salve.
Vainio-Kaila points out that all parts of a tree have medicinal uses. - If antibacterial materials can be used in contact surfaces in public spaces, we will reduce the transmission of various infectious diseases spread by hand. There are many insights and practical applications that can be developed from these antibacterial properties. The only limit is in our imaginations.

Abstract
The relationship between a control movement and the effect most expected by a population is known as a direction-of-motion stereotype. Such stereotypes are important in order to study the impact of different design variables on user performance. In this paper, a neural network-based method is proposed to quantify the causal connection among design variables and to compute their relative influences on the two performance measures of user response time and response accuracy. Based on the experimental data presented here, the best operating condition with which to optimize each of the measures is suggested. Some useful observations about the relationship between design variables and measures are also presented and discussed. In ergonomics, there have been a lack of useful quantitative methods for investigating the mappings between different displays and controls under a variety of operating conditions. The major contribution of this study is to provide some insight into the usefulness of quantitative methods in evaluating display-control compatibility.

In our post about caring for your guitars, we shared some simple storage and maintenance techniques to ensure that your guitars stay up-to-snuff and playable. However, that's only part of the battle when it comes to studio equipment. In fact, perhaps the most prevalent pieces of equipment are your electronics. These include the audio interface, the speakers, the monitors, your rack gear, your effects processors, your amps, etc. Needless to say, that is a lot of equipment to worry about it. This week, we'll give you some general storage, cleaning and maintenance rules for some of this equipment. You can also check out this article for some general electronics tips.
Much like our discussion on humidity and guitars, the environment is an important consideration for your home studio. In terms of electronics (in any room, not just studios), humidity is often neglected as an important concept. So what are the concerns here? Well, if your humidity is too high, that means that there is a significant amount of water/moisture in the air. Therefore, you run the risk of corrosion on the circuit boards or moving electronic parts. While the risk obviously isn't as extreme as, say, dumping a bottle of water onto your computer, why would you want to leave your electronics in a room with a lot of moisture 24 hours a day?
Of course, keeping the humidity extremely low isn't the answer either. At low humidity levels, the risk of strong static charges increases substantially. This could actually cause certain components in your computer, speakers or rack units to short out or wear more quickly. So, the name of the game here is prevention. Make sure you keep your studio within an ideal humidity range (roughly 30"60% humidity) at all times. While you should be fine within this range, it's often better to be closer to the lower end (30"40%), simply because the risk of static charge is a little less likely/damaging than extended humidity exposure. Keep in mind when using humidifiers or dehumidifiers that humidity levels fluctuate with the seasons (and depending on your location). Keep things within this range, and you'll have a decently safe place to store your gadgets.
Maintenance and Cleaning
We'll close this article with some simple tips to keep your music electronics clean and maintained. In general, it's fairly obvious to make sure your electronics are dust-free as often as you can. While this may seem obvious, it's often neglected. Simply dusting your electronics each day (using a cloth or dust pad), will eliminate a lot of the dust that might get inside of the electronics. If the enclosures are easy to open, you could dust the insides as well, but be wary as there is risk of breakage.
Disclaimer: Don't attempt to open up electronics unless you understand how they work, as there is always a risk of shock. Please follow the manufacturers' warnings.
Finally, a few emergency tips are in order. If you are cleaning your monitors or surfaces with cleaners, be cautious about which ones you use. Many computer monitors can be sensitive to many household cleaners (as can most electronics). Also, be aware of how much pressure you are using to clean monitors, as pressing down too hard can cause indents or even cracking (particularly in LCD screens).
Beyond this, if you've reached the point of no return by either spilling a liquid on your device or you begin to notice an electrical burning smell, turn the device off immediately. While a burning smell can indicate many different things, and we recommend seeking a trained technician, many guitar amps will smell like this if a fuse or tube is overheating. Therefore, turning off the device and letting it cool down may solve the problem. Shutting off a device and letting it dry after spillage can also solve the problem, as water will only cause short-outs if the device is on (in most cases).
Disclaimer (again): Don't open the device and try to fix it if you don't know how to as there as a huge risk of dangerous electric shock. The bottom line: if you are worried, seek a technician's opinion.
Overall, your studio contains a lot of electronics (even the heart of most home studios, the computer itself). So, neglecting to care for these crucial machines can cost you a lot and even prevent usage of your studio.


TY - CONF TI - A simple repair mechanism can alleviate computational demands of pragmatic reasoning: simulations and complexity analysis AU - Arkel, Jacqueline van AU - Woensdregt, Marieke AU - Dingemanse, Mark AU - Blokpoel, Mark AB - How can people communicate successfully while keeping resource costs low in the face of ambiguity? We present a principled theoretical analysis comparing two strategies for disambiguation in communication: (i) pragmatic reasoning, where communicators reason about each other, and (ii) other-initiated repair, where communicators signal and resolve trouble interactively. Using agent-based simulations and computational complexity analyses, we compare the efficiency of these strategies in terms of communicative success, computation cost and interaction cost. We show that agents with a simple repair mechanism can increase efficiency, compared to pragmatic agents, by reducing their computational burden at the cost of longer interactions. We also find that efficiency is highly contingent on the mechanism, highlighting the importance of explicit formalisation and computational rigour.

How Does a Garbage Truck Work?by Dale Devries
In 1938 the Load Packer was introduced by Garwin Industries, which revolutionized the sanitation industry. It was the first true compacting garbage truck. The trucks at that point could carry twice as much as before because they could compact the trash while driving through the city. By the 1950s there were many of these garbage trucks in use, and other manufacturers also started making them. By the late 1950s and early 1960s they started to manufacture industrial-strength compacting trucks. These trucks could handle larger objects and compacted better, allowing them a 25 percent larger load.
How the Compactor Works
The trucks are loaded by sanitation engineers along neighborhood streets. The trash is loaded into a hopper in the back of the truck of rear loaders. Hydraulic cylinders operate the compacting mechanism, which takes the trash out of the hopper and places it into the body of the truck. As more trash is placed into the body, the more it gets compacted. Because the compacting unit is on the outside of the body of the truck, it keeps the trash from falling out of the truck when it is full or moving. When the truck is full the driver takes the trash to the dump. The rear of the truck tilts up like a dump truck and the hydraulic cylinders move the compacting panels out of the way. The trash is then dumped out of the truck and the back hosed out.
Other Types of Garbage Trucks
There have been many variations of the garbage truck since its invention. The front-loading truck has a hopper in the front of the truck at about waist level to the workers. They load into the hopper and it takes the garbage up over the top of the truck and dumps it into the body. It is then compacted and this truck dumps the same as the rear loader. Recycling trucks also come in various versions. Some are side loaders in which the hoppers are on the sides and lift up into the truck. Some have separate hoppers for each type of recyclable material. There is even one type that has a robotic arm that grabs the can from the side of the street, goes up a conveyor, dumps the material and places the can back on the street. This is a similar operation to the commercial garbage bins you see outside of restaurants and other businesses. These trucks normally collect the bin from in front of the truck, lift it over the truck and dump into the body of the truck. These types of trucks take away the need for more workers.

type, sun exposure, and irrigation.
The type of soil plays a significant role in determining the appropriate spacing distance for bells of Ireland. These plants thrive in moderately fertile and well-draining soils. The soil should be rich in organic matter and should not hold onto water as waterlogged soil can cause root rot. You can test your soil type by performing a soil analysis to determine the pH level, nutrient level, and soil texture. Usually, the soil should have enough space for the plant to grow freely while preventing overcrowding, which could compromise growth. Spacing for bells of Ireland should be about 15 to 18 inches apart in all directions.
Bells of Ireland need full sunlight to grow optimally. Adequate sun exposure allows the plants to produce more buds and flowers, making them more attractive. When determining the plant spacing, gardeners should consider the amount of sunlight the area receives. If the soil gets partial or minimal sunlight, then the plants should be spaced at least 18 inches apart. If the soil receives full sunlight, a spacing distance of 12-15 inches is acceptable.
Bells of Ireland require moderate watering to thrive. Gardeners should ensure that the soil is evenly moist, but not waterlogged. Overwatering can cause root rot, which can result in the plant dying. On the other hand, inadequate watering can lead to the plant withering. When planting, the gardener should not place the plants too close to each other, as it can lead to overcrowding, causing the plants to compete for water. Therefore, the recommended spacing for bells of Ireland must be 15-18 inches apart.
In conclusion, spacing for bells of Ireland plants is necessary to ensure healthy growth, proper airflow, and pest control. Three important factors gardeners must consider before deciding on the appropriate spacing distance are soil type, sun exposure, and irrigation. For best results, gardeners should space their bells of Ireland plants about 15-18 inches apart in all directions. Taking these factors into consideration will help gardeners enjoy the beauty of these delightful plants for years to come.

First and foremost, it is essential to space bells of Ireland plants properly. These plants can grow up to 3 feet tall and about 18 inches wide. Therefore, spacing should be at least 18 inches apart. This ensures that there is enough room for each plant to grow to its full potential.
Bells of Ireland require well-draining soil that is rich in organic matter. Before planting, it is recommended to amend the soil with compost or other organic materials. Additionally, it is important to ensure that the soil remains moist but not waterlogged.
Sun and Water
Bells of Ireland require full sun to partial shade, with at least 6 hours of direct sunlight each day to thrive. It is also essential to provide adequate water for these plants. They require consistent moisture, especially during dry spells. However, overwatering can lead to root rot and other fungal diseases.
Bells of Ireland plants require regular fertilization to maintain healthy growth and abundant blooms. It is best to use a balanced fertilizer that is high in phosphorus, which promotes flower production. Fertilize the plants about once a month during the growing season, but be sure not to over-fertilize, which can cause weak and spindly growth.
To encourage healthy growth and prolong the blooming period of bells of Ireland, it is essential to prune them regularly. Deadhead the fading flowers by pinching them off at the base of the stem. Pruning encourages the plant to produce new blooms and also helps to keep the plant tidy.
In conclusion, these are some best practices and tips for spacing bells of Ireland to create an attractive and healthy display. Proper spacing, well-draining soil, adequate sun and water, regular fertilization, and consistent pruning are essential for the healthy growth and abundant blooms of bells of Ireland.

Google has been known to do some interesting things with the data it collects from users, and here is yet another example of that. The company has found a way to visualize the data collected from Play Music users and display it on a Google Music Timeline. This timeline offers a visual representation on the growth and decline of certain genres of music (via Google Operating System Blog).
The graph displays a colored stripe for each genre of music. The thickness of each stripe represents the popularity of that genre in a given year. The data is collected from the music uploaded to Play Music by users. For instance, the Jazz stripe is thickest in the 1950s because many users have Jazz content released in that time period in their library.
The Music Timeline shows genres of music waxing and waning, based on how many Google Play Music users have an artist or album in their music library, and other data (such as album release dates). Each stripe on the graph represents a genre; the thickness of the stripe tells you roughly the popularity of music released in a given year in that genre. (For example, the "jazz" stripe is thick in the 1950s since many users' libraries contain jazz albums released in the '50s.) Click on the stripes to zoom into more specialized genres.
