Human Intruder Detection (HIDS)
Monitoring the baggage system at the airside/landside boundary to prevent unauthorised or accidental intrusion thus creating a secure airside zone.
The landside/airside boundary is meant to be a barrier that prevents unauthorised people being where they shouldn't however due to the way an airport operates there must be holes in that boundary to allow or people or bags to travel back and forth. Whilst personnel access can be easily monitored/controlled the challenge with baggage handling is identifying human intrusion whilst allowing bag movement without false alarming.
Using an Artificial Intelligence (AI) based belt monitoring system is a new way to tackle the problem of human (and child) intrusion through the baggage system.
With machine learning algorithms at the heart of the solution, and using multiple technologies, the system has been taught the difference between bags and humans and over time the system continues to learn the difference between what is a bag and what is a human, getting more and more accurate.
This means that it is not affected by any of the problems associated with just thermal based systems such as hot bags causing false alarms and needing regular recalibration or light curtain based systems which won't detect a human attached to a bag or underneath a bag. The system can also be applied to detect other anomalies within the baggage system such as bags left lying around, multiple bags in a single tray or bags falling off trays from tilt tray sorters.
The system is easily deployed to cover the baggage system using off the shelf components and architecture. As with other Saconsys solutions we believe that in order to maintain uptime and control costs we teach and support the airport to maintain the equipment – this means no costly maintenance contracts or waiting for engineers to attend site.
The system is also scalable meaning that you can add as you go along rather than having to make a large investment on day one.

Famous tree-lined French Canal du Midi in danger of losing all its trees
The 42,000 plane trees lining France's historic Canal du Midi are being felled because of a fungus brought to Europe by US soldiers in World War II. Will the planes that decorate the streets of cities such as Paris and London share the same fate?
Story from PRI's The World. Listen to the above audio for a full report.
It's noon in the farmlands outside Toulouse, but the light on the Canal du Midi is dim, almost like twilight.
The deep shade is created by the leafy branches of huge plane trees that tower above both banks, and arch across the water creating a dense canopy.
It's an exquisitely beautiful scene. And one that runs the length of the canal on its 150 mile course from Toulouse to the port of Sete on the Mediterranean.
It was five years ago that Jacques Noisette realized something was wrong.
"In the spring of 2006, I began to notice that some of the plane trees were dying," says Mr Noisette, who works for the French government agency that manages the canal.
"Their new leaves should have been opening up, but they weren't. We asked ourselves why."
Specialists soon identified the deadly fungus, Ceratocystis platani, for which there is no apparent cure.
"Even a small scratch or cut on a plane tree is enough for the fungus to get inside and attack. It thrives deep in the tree trunk," says Mr Noisette. "Within three to five years the tree is fully infected. There's nothing we can do except cut the trees down, and burn them on the spot."
Researchers say the trees must be felled before they die. Otherwise they could fall on boaters, who travel along the canal - spreading the fungus as they go.
"We know the fungus travels through the canal water," says Mr Noisette. "The trees can get infected when boats scrape up against the roots. Or when uninformed boaters tie-off their boats to the plane trees themselves."
French agronomist Andre Vigouroux, who has been studying the fungus for years, says it's been traced to the munition boxes American soldiers brought over to Europe in World War II, which were made from North American plane trees.
It's been spreading through Europe, from Italy, and Steve Woodward from the University of Aberdeen, says it is likely eventually to kill the planted planes that line the streets of cities such as London, Paris and Berlin.
"There really are millions of these trees planted in non-native areas.
"We are talking about a massive disaster if the disease continues to spread," he says.
Along the canal tree-felling has begun - 1,000 trees were cut down last winter, 2,000 more will be felled in the coming months.
It will take years to clear all 42,000 of them, but once the trees have gone, so may the two million tourists who visit the canal every year.
"It is so hot in the Midi that it would just change it totally without the trees," says retired British tourist Graham Barley, who has been travelling up the canal from the Mediterranean in a wooden houseboat.
His wife Linda agrees. "In practical terms, it would make cruising between noon and 4pm unbearable," she says, even in September.
The Canal du Midi wasn't originally designed for pleasure boats.
Completed in 1681, it was designed to link up with another waterway further west - now known as the Canal de Garonne - to allow merchants to move between the Atlantic and the Mediterranean, without having to sail around Spain and Portugal. The sea route was long and arduous, and ships could fall victim to storms and pirates.
The plane trees were a later addition, planted in the 1830s in part to provide shade to those using the waterway.
UNESCO declared the canal a world heritage site in 1996, saying it had "provided the model for the flowering of technology that led directly to the Industrial Revolution and the modern technological age". To retain this status, however, France will have to replant the trees it chops down.
So that's the plan. To replant a variety of trees where the plane trees now stand. Trees with strong root systems to maintain the canal banks, and with thick leaves to create shade.
And ironically, given that American GIs brought the fungus to Europe in the first place, among the new trees to replace the old are 7,000 disease-resistant plane trees - all the way from Mississippi.
Whether colder parts of Europe will be able to use the Mississippi strain to replant any planes they lose in the future, is as yet unknown.

How to Obtain a Government Proclamation
A proclamation is a formal announcement made by a state or local government on a topic important to members of that community. Asking your state or local government to issue a proclamation for National Chiropractic Health Month (NCHM) is a great way to raise awareness of chiropractic services.
How do I get started?
1. Start early. It may take some time to go through the proclamation process, so begin at least 4-8 weeks in advance of National Chiropractic Health Month.
2. Identify who handles proclamations in your local city, county or state government offices by looking on city, county and state Web sites, checking the government pages in the phone book, or by calling the offices. If there is no one who deals exclusively with proclamations, try talking to a public relations or public information officer. An office manager or an office administrator may be able to help, as well.
3. When calling the proclamations office, be prepared to provide information about the importance of conservative care for people in your area. You can use statistics and information provided in ACA's sample NCHM proclamation or other NCHM resources. Also be sure to ask the right questions:
- What is the process to get a proclamation?
- Do they want you to draft the proclamation or to do it themselves with information you provide?
- How would they like to receive the proclamation text: hard copy, an electronic version or both?
- Can you arrange a signing ceremony and invite media?
4. When submitting the required documents to the proclamation office, remember to include the following:
- A cover letter with some facts about the importance of conservative care as a way to stem the opioid epidemic. Be sure to mention that your clinic/organization will be celebrating National Chiropractic Health Month along with the American Chiropractic Association and doctors of chiropractic nationwide. Note that the goal of NCHM is to bring attention to how chiropractic care can help people feel and perform their best naturally. Also include the date and theme of the proposed proclamation (October; Back to Basics) and your contact information.
- A draft of the proposed proclamation (see ACA's sample proclamation).
5. Mail and/or hand deliver your cover letter and draft proclamation to the office. If you have not heard back from the office after a week, follow up on the status of the proclamation by phone and/or e-mail.
6. Once the proclamation is signed, go to the office and pick it up in person. While you are there, be sure to personally thank the staff member who helped you. This may help the process go much quicker next year! If you are able to arrange a signing ceremony, be sure to take pictures and send them with the ACA Communications Department. We will share your good news via our social media channels!
7. Draft a thank you letter to the official who signed the proclamation.
8. Display the proclamation in your office the entire month of October. In addition to enhancing the credibility of the chiropractic profession and your clinic, the proclamation is another way for you to begin a conversation with patients about the importance of a conservative-care-first approach to health care.

Sales and Use Tax Calculation feature
The result is that you can use the KampData TaxEngine to calculate tax outside of Microsoft Dynamics GP with no additional tax setup required.
Call the DocCalculateTax method to calculate or re-calculate the tax. When this method is called, tax detail records will be created in the Transaction Tax table. When an order is created outside of Dynamics and subsequently imported into Dynamics, Tax Detail records should be created in the appropriate Dynamics transaction tax table. For SOP this table is the Sales Taxes Work And History table. The following tax detail data can be retrieved from the Transaction Tax table or by using the KampData TaxEngine methods and properties such as the following:
- DetailTaxDetailID property
- DetailAccountIndex property
- DetailTaxedAmount property
- DetailTaxAmount property
The document tax details can be retrieved as an ArrayList using the DocTaxDetails method. Alternately you can step through the tax details one by one using DocTaxDetail method. The number of tax details available to step through can be retrieved using the DocTaxDetailsCount method.

Hobby horses as a hobby
Location Finland
Tags hobbyhorses, crafts, sports, hobbies, children, young people, riding, keppihevoset, lapset, nuoret, harrastukset
Practitioners and people who know the tradition well
Thousands of children and young people all around Finland are hobby horse enthusiasts. They are usually of school age or older, and the nature of the hobby usually depends on the enthusiast's age and the aspect of the hobby they are interested in. Commonly, people who no longer feel like they play with hobby horses but instead participate in the hobby regularly and in a goal-oriented way are considered to be hobby horse enthusiasts. There is no accurate information about how many enthusiasts the hobby has, because only a few have reported on listings or are members of an association. According to the most optimistic estimates, Finland alone may have more than 10,000 enthusiasts.
Hobby horse activities are promoted by the Finnish Hobbyhorse Association (Suomen Keppihevosharrastajat ry).
Practising of the tradition

Hobby horses represent an extremely versatile hobby, and everyone can pick the parts they want, creating a hobby they like best. Essential parts of it include making the hobby horses, riding, communality, and competitions. The hobby mimics riding live horses, and in fact, you can practise all aspects of riding with a hobby horse.
Hobby horses as a hobby are based on the enthusiasts' own initiative, which makes the hobby very free-form. There are no hard and fast rules: anyone can enjoy the hobby in the way they like. Hobby horses are also suitable for people who cannot or do not want to ride. Others organise competitions, training events and coaching.
Almost all hobby horse enthusiasts make hobby horses in the course of their hobby. You can make a hobby horse in any way you can imagine: sock horses are made out of socks, felt horses are felted, and traditional fabric horses are sewn out of fabric. Fabric horses are often divided into two-and three-piece horses, depending on whether a middle piece has been used to make the hobby horse or not. The horses are also divided into those with and without a mouth. Many enthusiasts focus on making and selling hobby horses, and they try to create horses that are as realistic as possible.
You can practise any kind of equestrian sport with a hobby horse. Traditionally, the most popular sports have been show jumping and dressage.

In show jumping, the horse and the rider jump over a set show-jumping course, and faults are received for any railings that are knocked over. The classes can be judged based on time or style. In dressage, participants are judged on the ability of the horse and the rider to complete a predetermined programme as accurately and realistically as possible, just like riders with live horses.
In addition to competitions, hobby horse enthusiasts also organise coaching events and camps for each other in different parts of Finland. Most events are organised by children and young people, and at other times, they are organised by clubs or associations. The Finnish Hobbyhorse Association organises Finnish national championships in show jumping and dressage for hobby horses every year.
Enthusiasts keep in touch with each other via social media, and they meet at events and competitions. Online shows and competitions are also an important part of the hobby.
The background and history of the tradition
Children have played with hobby horses for millennia. In the late 1900s, the game started to become a hobby in small concentrated areas in different parts of Finland. In the early 2000s, hobby horse enthusiasts started to gather together in online discussion forums and websites. An unofficial hobby horse association was established in 2004, and it was later registered as Suomen Keppihevosharrastajat ry (the Finnish Hobbyhorse Association). As social media became more popular, hobby horses spread out further and further over the internet, and the general public became more aware of them.
The transmission of the tradition
Many enthusiasts riding their hobby horses.

Most of the hobby horse activities take place online, where the enthusiasts meet, share tips and agree on meetings. For the younger generations, social media is a natural channel for sharing information and learning about the hobby, while also passing on the hobby horse tradition. Hobby horse competitions, camps, lessons and coaching play an important part in passing on skills and knowledge. The Finnish Hobbyhorse Association also offers its members training and information about the hobby.
The future of the tradition
The number of hobby horse enthusiasts has grown rapidly in the recent years, and that number shows no sign of diminishing. With the lists it keeps, the Finnish Hobbyhorse Association aims to map the number of enthusiasts and offer a hub where they can meet. The enthusiasm of hobby horse enthusiasts is also increased by the annual show jumping and dressage championships for hobby horses; the association has organised them since 2012.

Intrepid Toddler's Daring Crib Escape Caught on Tape [VIDEO]
It's every parent's worst nightmare: Your toddler would rather go exploring than stay in the safe confines of his crib. So he does. Over and over and over.
One mother found herself in such a situation and couldn't figure out how her child kept escaping. So, she set up a camera in the kids' closet. Sure enough, she captured the child, whose name is Dayne, making a break for it not once, but twice.

Assertions for debugging
Use only in the MuPAD Notebook Interface.
This functionality does not run in MATLAB.
The statement assert(cond) declares that the condition cond holds true at the moment when the statement is evaluated. By default, MuPAD® does not care about assertions. After setting testargs(TRUE), however, MuPAD checks every assertion and stops with an error if boolean evaluation of cond does not give TRUE.
Assertions are a major debugging tool for programmers: by stating frequently what they think to have achieved, programmers make it easy for themselves to detect the first unintended intermediate result.
Example 1
Suppose we want to write a function f that takes an integer as its argument and returns 0 if that integer is a multiple of 3, and 1 otherwise. One idea how to code this could be the following: given an integer n, n modulo 3 must be equal to one of - 1, 1, or 0. In any case, abs(n mod 3) should do what we want:
f := proc(n: DOM_INT): DOM_INT
local k: DOM_INT;
 k := n mod 3;
 assert(k = 1 or k = -1 or k = 0);
Checking assertions is switched on or off using testargs:
oldtestargs := testargs(): testargs(FALSE): f(5)
The result does not equal 1. For debugging purposes, we switch on assertion checking:
testargs(TRUE): f(5)
Error: Assertion 'k = 1 or k = -1 or k = 0' has failed. [f]
This shows that the local variable k must have gotten a wrong value. Indeed, when writing our program we overlooked the difference between mod and the symmetric remainder given by mods.
A boolean expression
Return Values
assert returns TRUE or raises an error.

The c/a ratio, spontaneous polarization, and tetragonal-to-cubic phase transition pressure systematically decreased with increasing Bi 3+ substitution. In contrast, hole doping hardly affected the tetragonal distortion and structural stability. We showed that electron doping is an effective way to control the stability of the tetragonal phase of PbVO 3 with a 3d 1 electronic configuration.

Diminutive/affectionate form for the name Anatole?
Hi everyone!
I'm looking for a dimunitive/affectionate form for the name Anatole which would be used in a French or French-speaking family (or by a French/French-speaking lover and/or close friend). If different diminutives exist and they have different conotations (like one is something that could be used by friends but another is too "fluffly" and would most likely only be used by a parent) please let me know that sort of information too.
I've tried to google this, but all I'm getting is other versions of the name (like alternate spellings, eg: Anatol, or from other languages, eg; Anatoliy, which is the Russian version of this name). But I'm interested specifically in a diminutive/affectionate form.
(Also, I don't know if this matters, but the time period the story is set in is early 1800s. It seems to me that there isn't a lot of difference between how diminutives function now versus how they functioned then, just language convention wise, but I'm not sure? I know with a few Russian names there are minor differences (eg: for the name Dmitri, the diminutive Mitya was most common at that time, whereas now Dima is more common), so I thought I would mention this. If you know of a difference in which diminutives were used then v now, I'd be interested in that information too.)
Thank you!

Sheep on Romney Marsh
The original Romney Marsh sheep were developed on low lying land in Kent and Sussex, adjoining the English Channel. The area was, and still is, exposed and isolated, so that a hardy breed of sheep was produced requiring the minimum of attention.
The breed expanded over the rest of the South East of England and became known as Kent Sheep. It then spread all over the world and the name Romney came into general use. The vast sheep industries of New Zealand and many other countries had their origin in the Romney sheep. For this reason, it is often referred to as 'the best-known sheep in the world'.
It is said that the first sheep were brought to Britain by the Phoenicians sometime between 800 and 500 BC. Certainly, the Romans brought sheep with them when they invaded Britain in 43AD but it is not clear whether they had them on Romney Marsh, as Winchester was the centre of their wool industry.
Sheep have grazed the marshes for centuries, the quality of its pastures is renowned. By 14th century England's most important commodity for internal trade and export was wool. This continued until in the 16th century when wool prices in England fell forcing traders to export more to the continent.

But in 1660 a bill was passed preventing traders from exporting. With a long sea coast facing France there had always been a history of smuggling on Romney Marsh but the introduction of the Wool Acts of 1660 & 1699 led to an increase, especially on Romney Marshes. Incidents of smuggling continued to escalate in the 18th & 19th centuries until the government made a concerted effort to suppress it.
In l939 there were some 200,000 sheep on the marsh, but during World War II the sheep were sent away to the hill farmers in Yorkshire and the numbers of sheep on the marshes were halved, arable farming increased four-fold to 15,000 acres and this trend continues with the exception of areas that are Sites of Special Scientific Interest (SSSI) or Nature Reserves.
For centuries the raising of sheep for the wool market was the most important part of the trade of Romney Marsh. The Romney (originally called Romney Marsh) is one of the oldest known sheep breeds, with its origins having been traced back more than 700 years to the 13th Century and possibly earlier.

The plague in 1346, the Black Death had a major effect on sheep farming on Romney.
History of the Romney Breed
 - The Romney breed became indigenous ie native to the Romney Marsh in c 13th century.
 - In the middle ages, the English woollen industry was the most important export commodity
 - The Romney was recognised as a pedigree breed in England in 1896.
 - The Romney is known as a "semi long-wool" sheep, an efficient grazier with a good return on meat and wool.
 - Dual purpose breed bred both for wool and meat and exported around the world.
 - In the late years of the 20th century the breed was considered old fashioned, pushed aside by continental breeds.
 - Re-established their place in the 21st century farming.
The Romney sheep has the highest quality of fleece on any native British breed of sheep. The fleeces have long, crimped staples which are easy to spin and soft enough to use in the production of clothing.

The Romney Breed
Romney sheep are a hardy and adaptable English lowland breed, being a familiar site on their indigenous areas of the Romney Marsh and lowlands of the south east coast of Kent and Sussex, England. They are a dual purpose breed, bred for both their wool and meat.
The geographic and climatic conditions on Romney Marsh led to the development of specific characteristics in the breed. These traits include black hooves resistant to footrot, resistance to internal parasites, excellent fertility and milking/mothering ability, fleeces that withstand high rainfall and a constitution that tolerates harsh, wet conditions.
Romney was developed from the native European white-faced, long-tailed sheep and took its name from the low-lying Romney Marsh area. By 1800 it was recognised as "Romney Marsh" or "Kent" and the breed's quality improved with Leicester blood. It was recognised as a pedigree breed in 1896.
Romney Marsh sheep have white faces and a heavy fleece, and being big framed sheep they are a dual-purpose breed, providing excellent meat as well as wool. While the meat is renowned for its flavour, the fleece uniquely combines several important traits - being lustrous and hanging in separate locks. High yielding and easily spun, the wool clip from the pure-bred Romney flock is sought for many commercial products, ranging from sweaters to carpets. The fleece is also especially attractive to handspinners.
Romney Sheep and Lambs
Romney Sheep and their lambs
Flocks on Romney Marsh were many times larger than those in other parts of Kent and in 1700 there were an estimated 160,000 sheep on the Marsh. Local men were employed to tend these flocks. These men became known as Lookers and are distinguished from shepherds by the fact that Lookers cared for sheep of more than one owner, whereas shepherds were employed by a single owner. The Lookers lived in the villages and had to travel some distance to tend the sheep. This necessitated the construction of sheephouses, known as Lookers' Huts.
Romney Wool
Romney Wool is a natural cream colour, semi-lustrous with a long staple, often used in knitting yarns, etc. The Axminster carpet company in Devon use Romney wool in their wool carpets.
Lanolin is a yellow waxy substance found in the sheep fleece. Lanolin's role in nature is to protect wool and skin against the ravages of climate and the environment. As a natural occurring fat in wool, it keeps the hands of sheep shearers and wool sorters so exceptionally soft. This makes lanolin a simple and natural product for Wool Fat Soap, first produced in the early 1930's. The soap, and related products, has many beneficial attributes, being it is gentle, rich and soothing and helps keep skin hydrated.
What Makes Wool So Special?
Wool is becoming a more popular choice as it is a renewable resource and a natural product. In Jan 2010 the Prince of Wales convened the 'Campaign for Wool' which aims to educate the world about the versatility and sustainability of wool. Wool represents only 5% of the Worlds Fibre production.
Woollen Industry
Romney provided the foundation for the English woollen industry, which was the most important export commodity in the Middle Ages. Their long, dense fleece was highly prized, leading to widespread wool smuggling from the 14th to the early 19th Centuries. Live sheep were exported to other continents, enabling Romney to become the world's second most economically important sheep breed and to be known as a dual purpose breed—bred for wool and meat.
Romney sheep were exported internationally early in the 19th Century when a shipment was sent to New Zealand. Today the breed is distributed throughout England, New Zealand, Australia, Patagonia, Canada, Brazil, Portugal, Falkland Islands and the United States. Hence the claim, "The sun never sets on Romney sheep." Romneys have made an easy transition to New Zealand, where they became quickly established and still remain the predominant breed.

Local Farmers
Paul and Kristina Boulden are 6th generation family farmers on the Romney Marsh. They run a mixed farm consisting of arable farming and a suckler herd as well as their Romney flock. The sheep graze on clover-rich pasture and this plays an important role in their arable rotation.They have approximately 1000 ewes lambing in March/April.
In 2008 Paul and Kristina decided to diversify and set up Romney Marsh Wools, with the vision 'To Capture the spirit of Romney Marsh by creating an opportunity to take home a part of history, with our quality natural wool and to pass it on from generation to generation.'

A chemist for a pharmaceutical company wants to determine the median reaction time for a newly developed antacid.
- Open the sample data, AntacidReactionTime.MTW.
- Open the bootstrapping for 1-sample function dialog box.
- In Sample, enter Time.
- On the Options tab, enter 1 in Base for random number generator.
Using Base for random number generator ensures that your results match the example.
- Click OK.
Interpret the results
The 95% CI indicates that the chemist can be 95% confident that the value of the median reaction time for the population is between approximately 8.8 minutes and 14.8 minutes. However, the histogram shows that the bars are very sparse, making it hard to see the sampling distribution. Because the sampling distribution isn't clear, the confidence interval may be unreliable. The original sample has only 16 data points. To get a reliable confidence interval, the chemist should collect a larger sample and perform the analysis again.

Brisk is one of those delightful words that sounds like what it means: quick, lively, bracing, and refreshing. There's nothing like a brisk walk in the morning to get the blood flowing and the spirit ready for the day.
Anything brisk is happening quickly but not too fast. Probably taken from the French brusque, which also means "quick," but in a more negative way, brisk can be used to describe not only physical actions but also more conceptual notions, such as brisk business around the holidays or brisk interactions at a speed-dating event. The soft-drink called Brisk must be called that for a good reason. Perhaps it picks you up!

Using UWB asset tags to dynamically create rt-ispace augmentations
Essentially, an asset tag is a small device that can be used to locate and instantiate, using UWB in this case, an augmentation in an rt-ispace environment completely dynamically. The augmentation follows the position and orientation of the asset tag, making for a very simple way to implement augmented spaces. If engineered properly, it could be an extremely simple piece of hardware that would be essentially UWB hardware along with a MEMS IMU and a battery. Instead of WiFi as in this prototype, pose updates could be sent over the UWB infrastructure to make things really simple. Ideally, these would be extremely cheap and could be placed anywhere in a space as a simple way of adding augmentations. These augmentations can be proxy objects (all aspects of a proxy object augmentation can be modified by remote servers) and can be as simple or complex as desired.
There are some similarities and differences with the ArUco marker system for instantiating augmentations. The ArUco marker can provide an ID but that has to be matched with a previously instantiated object that has the same ID attached. Asset tags don't require any pre-configuration like that. Another problem with ArUco markers is that they are very affected by occlusion – even a wire running across a marker might make it undetectable. Asset tags are not affected by occlusion and so will function correctly in a much wider range of circumstances. They do require UWB enabled spaces, however. In the end, both styles of augmentation instantiation have their place.
Note that the asset tag doesn't need to contain the actual asset data (although it could if desired). All it needs to do is to provide a URL of a repository where the asset (either Unity assetbundle or glTF blob) can be found. The asset is then streamed dynamically when it needs to be instantiated. It also provides information about where to find function servers in the case of a proxy object. The rt-ispace user app (in this case an iOS app running on an iPad Pro) doesn't need to know anything about asset tags – they just inject normal looking (but transient) augmentation updates into the rt-ispace system so that augmentations magically appear. Obviously, this kind of flexibility could easily be abused and, in real life, a proper security strategy would need to be implemented in most cases. For development, though, it's nice for things just to work!
One application that I like is a shared space where people can bring along their virtual creations in the form of some asset tags and just place them in the rt-ispace space so that any user in the space could see them.
Another idea is that items in stores could have rt-ispace asset tags attached to them (like security tags today) so that looking at the item with an AR device would perhaps demonstrate some kind of feature. Manufacturers could supply the asset and functions servers, freeing the retail store from having to implement something for every stocked item.
The video above shows how the augmentation tracks the UWB tag around and that the IMU controls the augmentation's orientation. For now, the hardware is a complete hack with multiple components but it does prove that the concept is viable. The UWB tag (the white box on the floor under the figure's right foot) controls the location of the augmentation in the physical space. A Raspberry Pi fitted with an IMU provides orientation information and drives the resulting pose via WiFi to the rt-ispace servers. The augmentation is the usual glTF sample CesiumMan.
Linking AR augmentations to physical space using the ArUco marker system
Following on from the earlier work with ArUco markers, rt-ispace can now associate ArUco markers with augmentations in a space. The image above shows two glTF sample models attached to two different ArUco marker codes (23 and 24 in this case). Since these models are animated, a video also seems appropriate!
The image and video were obtained using an iPad Pro running the rt-ispace app that forms the front end for the rt-ispace system. A new server, EdgeAnchor, receives the AR video stream from the iPad via the assigned EdgeAccess, detecting any ArUco markers that may be in view. The video stream also contains the iPad camera instrinsics and AR camera pose, which allows EdgeAnchor to determine a physical pose in space of the marker relative to the camera view. The marker detection results are sent back to the iPad app (via EdgeAccess) which then matches the ArUco IDs to instantiated augmentations and calculates the world space pose for the augmentation. There are some messy calculations in there but it actually works very well.
The examples shown are set up to instantiate the augmentation based on a horizontal marker. However, the augmentation configuration allows for a 6-dof offset to the marker. This means that markers can be hung on walls with augmentations either on the walls or in front of the walls, for example.
A single EdgeAnchor instance can be shared among many rt-ispace users as no state is retained between frames allowing the system to scale very nicely. Also, there is nothing specific to ArUco markers: in principle, EdgeAnchor could support multiple marker types, providing great flexibility. The only requirement is that the marker detection results in a 6-dof pose relative to the camera.
Previously, I had been resistant to the use of markers, preferring to use the spatial mapping capabilities of the user device to provide spatial lock and location of augmentations. However, there are many limitations to these systems, especially where there is very limited visual texture or depth changes to act as a natural anchor. Adding physical anchors means that augmentations can be reliably placed in very featureless spaces which is a big plus in terms of creating a pleasant user experience.
Adding ArUco marker detection to rt-ai
There are many situations where it is necessary to establish the spatial relationship between a camera in a space and 3D points within the same space. One particular application of interest is the ability to use markers to accurately locate holograms in a space so that AR headset users see the holograms locked in the space, even as they look or move around the space. OpenCV has the ArUco marker detection included so that seemed like a good place to start. The screen capture above shows the rt-ai Aruco marker detector identifying the pose of a few example markers.
This is the simple rt-ai test design with the new ArUcoDetect stream processing element (SPE). The UVC camera was running at 1920 x 1080, 30 fps, and the ArUco SPE had no trouble keeping up with this.
This screen capture is a demonstration of the kind of thing that might be useful to do in an AR application. The relative pose of the marker has been detected, allowing the marker to be replaced by an associated hologram by a 3D application.
While the detection is quite stable, the ArUco SPE implements a configurable filter to help eliminate occasional artifacts, especially regarding the blue (z-axis) which can swing around quite a bit under some circumstances due to the pose ambiguity problem. The trick is to tune the filter to eliminate any residual pose jitter while maintaining adequate response to headset movement.
One challenge here is management of camera intrinsic parameters. In this case, I was using a Logitech C920 webcam for which calibration intrinsics had been determined using a version of the ChArUco calibration sample here. It wouldn't be hard for the CUVCCam SPE to include camera intrinsic parameters in the JSON associated with each frame, assuming it could detect the type of UVC camera and pick up a pre-determined matrix for that type. Whether that's adequate is a TBD. In other situations, where the video source is able to supply calibration data, the problem goes away. Anyway, more work needs to be done in this area.
Since rt-ai stream processing networks (SPNs) can be integrated with SHAPE via the Conductor SPE (an example of the Conductor is here), an AR headset running the SHAPE application could stream front facing video to the ArUco SPN, which would then return the relative pose of detected markers that have previously been associated with SHAPE virtual objects. This would allow the headset to correctly instantiate the SHAPE virtual objects in the space and avoid problems relying on inside out tracking alone (such as in a spatial environment with a repeating texture that prevents unique identification).
Embedding AI inference in the Spatial Networking Cloud
rt-ai is a system for graphically composing edge AI stream processing networks either distributed on multiple processing nodes or all running on a single node. In the latter case, shared memory can be used for transfers between the functional blocks, making it almost as efficient as monolithic code. So when it comes to embedding AI inference in a Spatial Networking Cloud (SNC), rt-ai makes perfect sense. However, the underlying network styles are completely different – SNC uses a highly dynamic series of multicast and end to end virtual links whereas rt-ai uses static MQTT or shared memory links. Each makes sense for the different applications so it is necessary to create a bridge between the two worlds.
Right now, bridging is done (for video streams) with the GetSNCVideo and PutSNCVideo stream processing elements (SPEs) that can be added to any video stream processing network (SPN). GetSNCVideo can grab SNC video frames from the configured stream source which then acts as an rt-ai source for the downstream SPEs. Once processing has been completed, the frames can be re-injected into SNC using the PutSNCVideo SPE. There can be similar bridges for sensor or any other type of data that needs to be passed through an rt-ai SPN

In order for individuals and families to achieve economic mobility, the communities they live in need to provide equitable access to high-quality education and jobs. Increased wages, adequate working hours and reasonable working conditions can help advance economic well-being and provide increased access to opportunities such as buying a house, paying for a college education or investing in a business.
Because of the complex social, economic and political issues that have affected economic mobility over several decades, solutions that help individuals and families achieve this "American Dream" require a multi-faceted, cross-sector approach designed to impact change at the systems level.
Now, we're building on our previous work on family economic security and family asset building to explore how community foundations can use the five competencies of community leadership to help families move beyond economic security and toward upward economic mobility through a new Economic Mobility Action Network.
Continued Economic Mobility Work
Building on the remarkable success of the pilot Economic Mobility Action Network, CFLeads will continue supporting community foundations that serve as local coalition builders through their economic mobility work. Read more about our continued economic mobility work in the press release below:

When you spin an asymmetrically weighted, 2D disk-shaped top, the heavy part actually rises to the top. Why is this?

In the second video it shows that this is because of friction but trying this on a frictionless surface won't do much: The disk will go up and down and still the heavy part will be on the top.

I think the solution has more to do with the tennis racket effect (see: _URL_
Let me clarify the disk with hole in it has two stable axes of rotation and one unstable one. The unstable one is through the hole and the stable one is across (below in green) and normal to the disk.
Axes Def
I have confirmed that without friction (and from the videos in the link above) when the disk is spun on the unstable axis, it will perdiodically flip. This is what caused it to flip when the disk was falling without friction.
The additional nuiance here is the once it is on the "upsidedown" oriention and friction is present then the unstable axis becomes stable.
If the hole spans from the center to the edge of the disk, then the center of gravity is at $$ \vec{c} = (0,-\frac{R}{6},0)$$ where $R$ is the outside radius of the disk. The principal moments of inertia about the center of mass are $$ \begin{aligned} I_{XX} & = m \left( \frac{\ell^2}{12} + \frac{29 R^2}{144} \right) \approx 0.2 m R^2 \\ I_{YY} & = m \left( \frac{\ell^2}{12} + \frac{5 R^2}{16} \right) \approx 0.31 m R^2 \\ I_{ZZ} & = m \left( \frac{37 R^2}{72} \right) \approx 0.51 m R^2 \end{aligned} $$
where $\ell$ is the thickness of the disk. Since $I_{YY}-I_{XX} = \frac{8}{37} I_{ZZ}$ this means that the y direction is the medium inertia value, x the minimum and z the maximum. Hence the instability about the y axis according to the Tennis Racket Effect.
I am working to qualify the above statement and I am going to update this post with my findings.

may you please explain why the axis through the hole is unstable, I would say it should be the one on the x-axis because it is not symmetrical. – Mhmd Dec 31 '13 at 12:43
_USER_ Any rigid body has three principal moments of inertia of different values. Rotation about the smallest and largest direction is stable, whilst rotation about the medium value is unstable. This is the tennis racket effect. – ja72 Dec 31 '13 at 16:17
I have added a little more about the mass moments of inertia on the post. – ja72 Dec 31 '13 at 16:58
The tennis racket effect/theorem can be accurately understood by the Poinsot-Binet Energy Ellipsoid. More reference is in Goldstein – Torsten Hĕrculĕ Cärlemän Dec 31 '13 at 17:24
I) Here we will give a qualitative rather than quantitative analysis. Consider first the axially symmetric 3D tippe top, which means that there will be two principal axis with maximal moment of inertia. (If we wish, we can for simplicity model the top as a spherically symmetric ball, with a heavy point mass off the geometric center $O$.) Empirically, we observe to a first approximation that:
 1. The angular vector $\vec{\omega}$ is mostly vertical and completes a small precession for each revolution of the top. (Let's assume that $\vec{\omega}$ is upwards rather than downwards.)
 2. The rotation of the top is around a point $Q$ somewhere between the geometric center $O$ and the center of mass $C$.
 3. The point $P$ of contact completes a small circular orbit for each revolution of the top.
 4. The top is mostly rolling without sliding. In other words, to a first approximation, it is static friction rather than kinetic friction, and hence the mechanical energy is conserved.
The angular momentum vector $\vec{L}$ will mostly point upwards but tilted a bit to the same (opposite) side as $C$ iff $O$ is above (below) $C$. In other words, the angular momentum vector $\vec{L}$ completes a small precession for each revolution of the top. We will assume that this precession of $\vec{L}$ (and the corresponding net torque needed for this precession) remains very small during the entire inversion process.
Now the torques of gravity and the normal force work in unison to increase the precession of $\vec{L}$. The cancellation of this torque can only come from the friction force acting in the same direction (horizontally speaking) as where the center of mass $C$ is.$^1$
Naturally, due to an imperfect rolling motion, the friction force will then tend to slide the point of contact in the direction of the friction force, thereby raising the center of mass $C$. (Del Campo showed that sliding friction must play an essential role in the inversion process, cf. Ref. 1. Of course sliding friction is also responsible for that the top eventually comes to rest and looses its mechanical energy.)
II) The asymmetric 2D discs$^2$ works similarly, although now the rotation will mainly be around the unstable principal axis with intermediate moment of inertia, leading to the tennis racket/Dzhanibekov effect, as correctly pointed out by ja72 in his answer, see also e.g. this Phys.SE post and links therein. In situations without friction, the tennis racket/Dzhanibekov effect explains the last unresolved part of the solution video.
 1. Richard J. Cohen, The tippe top revisited, _URL_ (hat tip: Leonida)
$^1$ Note that the friction torque argument in this Basic Saucer Physics 101 video seems to lead to the opposite effect where the center of mass $C$ gets lowered (rather than raised).
$^2$ The geometric details of the asymmetric 2D discs is to a large extent irrelevant for the effect.

What does lux mean in lighting?
When it comes to lighting, there are various terms you need to learn to choose the right fixture for your home.
So, what exactly is lux, and what role does it play in how we perceive and interact with our environment? This blog aims to explore what lux is, how it's measured, and its impact on both our home and well-being.
For high-quality lighting, browse our LED products today and upgrade your home with Light Supplier.
What is lux?
Lux is a unit of measurement that quantifies the intensity of light as perceived by the human eye in a specific area. This helps us understand how bright a light source appears in certain areas of the home.
This is defined as one lumen per square meter, measuring the amount of light that reflects onto a surface. Unlike lumens which measures raw light output, lux takes into account how light is distributed over an area and is perceived by the human eye.
The same amount of lumens can produce different lux levels depending on how spread out the light is.
The significance of lux in everyday life
Understanding lux is beneficial for creating an ambient atmosphere in your home. Higher levels of lux reduce eye strain, whereas lower levels create a more relaxing environment.
Certain work environments, such as plants or labs, have specific lux requirements to enhance safety and reduce eye strain and fatigue. In public spaces, adequate lux levels ensure visibility and safety during dark hours.
The role of lux in lighting design
The lux requirements of a space are determined when designing lighting for specific areas.
This has to consider certain activities that will take place in the room to enhance efficiency. For example, a kitchen will require a higher level of lux for safety when cooking.
Aesthetics also plays a role in lighting design. The level of lux chosen is often determined by the mood and atmosphere that is desired for the area. Lux can highlight certain architectural features or decor to accentuate the building.
Energy efficiency is also taken into account when determining the amount of lux needed. Lower levels of lux can reduce energy consumption and environmental impact.
Measuring and adjusting lux levels
Measuring lux levels
Lux levels need to be measured using a lux meter.
This quantifies the intensity of light in a given area, and the metres come in various options, such as hand-held devices for simple measurements to complex systems for detailed analysis.
To measure lux, place the meter where the light's impact is most critical. Focus on areas where natural light combines with artificial lighting and take various readings at different times of the day for accuracy.
Adjusting lux levels
If you require more levels of lux, you can add light sources, change the bulb type, or adjust and reposition the angles of the fixtures.
You could also install dimmers to allow for dynamic changes in lux levels for different activities. In areas where natural lights illuminate the surface, blinds, curtains, or window screens can help manage lux.
The impact of lux on health and well-being
When it comes to the impact of light on our health and well-being, our circadian rhythms are strongly influenced by light exposure. This regulates our sleep-wake cycles, and properly timed exposure to light can help sync these rhythms.
Light exposure has also been shown to increase our mood and reduce symptoms of depression. This is especially beneficial in the winter months when natural light is scarce.
For the elderly, adjusting lux levels can improve vision, reducing the chance of falls and accidents.

Indiana's first African-American physician is being honored on Tuesday, more than a century after his death, with a commemorative grave marker.
The unmarked grave that is believed to belong to Dr. Samuel A. Elbert, a physician who faced racial barriers attaining his medical degree at the Medical College of Indiana, will finally be turned into a headstone at the Crown Hill Cemetery.
The Indianapolis Historical Society along with the Aesculapian Medical Society have been working together to push the installment of the marker recognizing Elbert's achievements as one of the first black medical pioneers.
Senior archivist from the Indianapolis Historical Society Wilma Moore said, "Grave markers always suggest legacy and legacy is important to let folks know that you were here. They also suggest what you did when you were here and that you will not be forgotten. Certainly in Dr. Elbert's case his legacy is great."
According to the Indianapolis Star, Elbert challenged the the Medical College of Indiana in 1871, after they refused to recognize him as a student or grant him a medical degree despite paying tuition and attending classes. He eventually won the case, making him the first licensed African-American physician in Indiana.
Elbert's prominence in the medical community grew from serving for one term as president of the Indianapolis Board of Health to being appointed by then-President Benjamin Harrison to serve as the local pension surgeon in the late 1800s. He ended up declining the appointment after receiving opposition from whites in the medical community.
Elbert's grave marker will be unveiled at the Crown Hill Cemetery in a formal ceremony at 5:30 p.m. Tuesday.

Understanding Weight Normalized Deep Neural Networks with Rectified Linear Units
Bibtex »Metadata »Paper »Reviews »Supplemental »
Yixi Xu, Xiao Wang
This paper presents a general framework for norm-based capacity control for $L_{p,q}$ weight normalized deep neural networks. We establish the upper bound on the Rademacher complexities of this family. With an $L_{p,q}$ normalization where $q\le p^*$ and $1/p+1/p^{*}=1$, we discuss properties of a width-independent capacity control, which only depends on the depth by a square root term. We further analyze the approximation properties of $L_{p,q}$ weight normalized deep neural networks. In particular, for an $L_{1,\infty}$ weight normalized network, the approximation error can be controlled by the $L_1$ norm of the output layer, and the corresponding generalization error only depends on the architecture by the square root of the depth.

File Extension Search
.adu File Extension
Developer: Addictive Software
File type: Addict User Dictionary File
You're here because you have a file that has a file extension ending in .adu. Files with the file extension .adu can only be launched by certain applications. It's possible that .adu files are data files rather than documents or media, which means they're not meant to be viewed at all.
what is a .adu file?
Files stored in the ADU format are used by an application that can be added to word processing software or to text editing applications developed for Microsoft Windows-based systems. These ADU files are classified as data files because stored in a file with the .adu extension includes pieces of data which can be referenced by a word processing software or a text editor that has been added with the main application that is used to create, open and edit these ADU files. These ADU files are also called Addict user dictionary files due to the nature of the content of a file stored in the .adu format. The Addict software can be used to create, open and edit the content of an ADU file. Addictive Software developed the Addict software as an application which can be added to widely used word processing and text editing programs like Microsoft Word, Microsoft WordPad and Microsoft Notepad among others. This application can be installed by users of computers running on Microsoft Windows systems, so they can create and open these ADU files. The content of these ADU files include dictionary terms that can be referenced by the associated word processing or text editing software added with the Addict software, and this happens when the user accesses the grammar and spell checking features integrated into the word processing or text editor application. Files with the .adu extension are also used as reference data files when a user accesses the thesaurus features implemented into the associated word processing or text editor software.
how to open a .adu file?
Launch a .adu file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .adu file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .adu files aren't yet associated with it. In this case, when you try to open a .adu file, you can tell Windows which application is the correct one for that file. From then on, opening a .adu file will open the correct application.

Addictive Software Addict
Addictive Software Addict
Addictive Software Addict is a suite of applications that is integrated with a set of features for implementing grammar and spell checking functionalities into C++Builder and Delphi programs. As of this writing, version 4.4 of Addict is the latest release from Addictive Software. This new version includes the implementation of better compatibility support for C++Builder XE2 and Delphi, simpler to operate configuration dialogues and spelling features through an improved UI (User Interface) and an updated database for phonetic suggestions among other functionalities. Unicode support for this program's dictionary feature has also been implemented into Addict v4.4. This version is also integrated with backwards compatibility support for previous releases of Addictive Software Addict. Users could also find it quicker and easier to access the integrated features of Addictive Software Addict through the new editing controls integrated into this program's UI.
a word of warning
Be careful not to rename the extension on .adu files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.
what is a file extension?
A file extension is the set of three or four characters at the end of a filename; in this case, .adu. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.

Main Article Content
Notopterus chitala is a member of the primitive teleost lineage and considered as commercially important food fish. To study the concentration of sodium and potassium and the influence of fish size and condition factor on the bioaccumulation of these macro-elements, a total of 16 fish specimens of N. chitala were collected from the River Indus. Mean (±SD) body weight, total length and condition factor was found 250.32±113.93 g, 32.93 ± 4.85 cm and 0.647± 0.094. Fish samples were oven dried, grinded, ashed and digested into 1M HNO3 to make sample solution. Flame atomic absorption measurements were analyzed to detect the concentration of sodium and potassium with atomic absorption spectrophotometer. Mean concentration of sodium was found 255.51± 32.45 µgg-1 with range values 206.28-298.70 µgg-1, while potassium was observed 1327.15 ± 234.71 µgg-1 with range 815.08-1694.87 µgg-1 in wet body weight of wild captured N. chitala. Body weight, total length and condition factor represented insignificant correlations with the concentrations of sodium and potassium in N. chitala, indicating no dependence of fish size on the bioaccumulation of these essential minerals in the body of this fish species.

text: This article is a theoretical examination of tactility in the Czech surrealist filmmaker Jan Švankmajer's film Down to the Cellar (1983). Švankmajer's deployment of tactile images in a surrealist context shows the need for a discussion of the imagination's role in the embodied film experience. Departing from Laura Marks's The Skin of the Film, this article seeks to explore the surrealist embodied imagination through surrealist poetics of analogy, as defined by Andre' Breton, and the link between these and Walter Benjamin's writings on mimesis. Finally, the film is viewed from the perspective of Gaston Bachelard's ideas of ''the imagination of matter,'' where matter is seen as a highly potent stimulant for the imagination. Bachelard's notion of the imagination's multisensory properties further lends credence to Švankmajer's aims to liberate the imagination of the spectator through images that invoke touch.

Green Diary highlights artist Luke Jerram's new project "Aeolus," which seeks to capture the sound of wind passing through a landscape. According to Green Diary, Jerram received an £225K grant from the UK's Engineering and Physical Sciences Research Council (EPRSC) to create and tour Aeolus, an exploration of acoustics, wind, and architecture, which was inspired by a tour of desert wells in Iran that one local well-digger said sung in the wind. The artist has created a range of sculptures, installations, and live art projects, including the Plant Orchestra.
Aeolian wind harps were seen by Jerram as the best tools for capturing the sound of wind. "Long tensioned strings will resonate with the wind and will be heard by visitors inside the space. The ambition is to sonify the three dimensional landscape of wind. The public will be able to visualise this shifting wind map from within the space by interpreting the sound around them."
The piece will consist of components that explore light, including "hundreds of light pipes which both draw the landscape of light into the building and hum at a series of low frequencies. The tubes act to frame and magnify the landscape so that from inside the structure, at its centre, visitors can see through one hundred of these pipes simultaneously, contemplating an ever changing landscape of light."
The installation features a specially designed architectural space that will resonate and sing with the wind. EPRSC and the engineering groups of University of Southampton (ISVR) and University of Salford are involved and funding the project because they hope to learn more about how to make audible wind noises without electrical power or amplification.
The temporary installation will tour sites in the UK and elsewhere, and each location's unique wind and landscape sound will be recorded.

CFD investigation on wheel rotation modelling
Artikel i vetenskaplig tidskrift, 2018
It is well understood in the automotive community that wheels are a major contributor to the aerodynamic drag of passenger vehicles. The flow around rotating wheels is very complex due to the many separation regions created by very small tyre features and by the contact area of the tyre with the ground. Correct modelling of wheel rotation requires accuracy in the representation of the tyre geometry and proper boundary conditions to simulate the rotation. This paper proposes a hybrid approach for simulating tyre rotation which is simple to implement and does not suffer from the limitations of a sliding mesh approach, at the region where the tyre meets the ground. The method is first evaluated on a single wheel that is free standing and the results are compared to a full sliding mesh computation, which is considered to be the best possible numerical solution. The technique is then implemented on a complete vehicle model simulation and the results are compared against wind tunnel force measurements. The good agreement obtained in these test cases shows that the proposed approach is a promising solution to a more accurate numerical simulation of rotating wheels.
