Room database. ViewModel
Introduction
 - This series is going to be dedicated to the basics of Android Room library. I will be following the official google guide, HERE but I will be working in an order that makes more sense to me.
What is a ViewModel
 - The ViewModel class is designed to store and manage UI related data in a lifecycle contentious way. The ViewModel class allows data to survive configuration changes such as screen rotations. Basically its a class that eases the use of data in our UI components like fragments and activities
Problems faced by the UI
 - The Android framework manages the life cycles of UI controllers, like activities and fragments. The framework may decide to destroy or recreate a UI controller in response to certain user actions or device events that are completely out of our control.
 - When the Android system destroys and recreates a UI component for any reason it creates 2 main problems
1) Restoring the UI data : if a system destroys or recreate a UI controller any transient UI related data you store in them is lost. When an activity is recreated for a configuration change, the new activity has to re-fetch the data. To solve this problem we could use the onSaveInstanceState() method and restore its data from the bundle in onCreate(). However, this approach is only meant for small amounts of data, not large amounts like we will be using.
2) Asynchronous calls : the UI controller needs to be able to manage asynchronous calls and ensure that the system cleans them up after its destroyed the UI controller to avoid avoid potential memory leaks. This management requires a lot of maintenance and is ultimately a waste of resources since the object will have to reissue calls it has already made.
Why use ViewModel?
 - Now UI controllers are primarily intended to display UI data, react to user actions, or handle operating system communication, like permission requests. Making UI controllers also handle loading data form a database or network calls adds unwanted clutter to the class. This is also a violation of the separation of concerns principle that we try to abide by in programming. It also just makes the class harder to test.
 - A much better and more efficient approach is to separate out the view data from the UI controller logic. We can do this by creating a ViewModel
Creating a ViewModel
 - We will be using a ViewModel class that is responsible for preparing and managing the data for our activities or fragments.
 - ViewModel objects are automatically retained during configuration changes so data they hold is immediately available to the next activity or fragment instance. This means we can have large amounts of data and only make one asynchronous call. Solving our two problems from earlier. With all that being said lets look at the code.
public class WordViewModel extends AndroidViewModel {
 private WordRepository mRepository;
 private final LiveData<List<Word>> mAllWords;
 public WordViewModel( Application application) {
 super(application);
 mRepository = new WordRepository(application);
 mAllWords = mRepository.getAllWords();
 }
 LiveData<List<Word>> getAllWords(){
 return mAllWords;
 }
 public void insert(Word word){
 mRepository.insert(word);
 }
}
Enter fullscreen mode Exit fullscreen mode
public class WordViewModel extends AndroidViewModel
 - The first thing that you probably noticed is that instead of extending ViewModel we extend AndroidViewModel. AndroidViewModel is a subclass of ViewModel so it does all of the same things that ViewModel does. The only difference is that AndroidViewModel is meant to be used when we are using global application context like we are. So just know that we are using AndroidViewModel over ViewModel because our program uses application context.
private WordRepository mRepository;
 - This is just a private member variable of type WordRepository. Remember a repository is an abstraction layer that we created for interacting with the database.
private final LiveData< List< Word > > mAllWords
 - Just another private final member variable but it is of type LiveData which will ultimately be used to store an updateable list of data.
public WordViewModel( Application application){...}
 - This is our constructor and we pass it a argument of type Application which is the global state of our application. We need to pass it this variable because AndroidViewModel needs it to operate properly. By calling super(application) we are calling the public constructor of AndroidViewModel. Our WordRepository also needs this application context.
mRepository = new WordRepository(application);
 - The next thing we do inside of our constructor is assign the member variable mRepository an actual instance of our WordRepository. This is important because if we don't do this we can not interact with our database. Also, notice that we are passing it application this will get used by our database when instantiating.
mAllWords = mRepository.getAllWords();
 - Here we are assigning a LiveData set of words to our mAllWords member variable.
LiveData< List < Word > > getAllWords(){...}
 - Just a basic getter method of our data of type LiveData. This method will eventually be used to hook up our data to our UI.
public void insert(Word word){...}
 - This is used to insert a Word entity into our database. Notice that we are interacting with the database through our repository.
 - With that we have successfully created a basic ViewModel.

Winny
Winny's Protocol (handshake)
Posted on August 10, 2008. Filed under: P2P, Winny |
For those who are interested, here's the protocol details about Winny.
I will first talk about the handshaking which is the beginning of all connections, the handshake begins with 6 bytes of data which contains the RC4 key used for decryption of upcoming data, the 6 bytes has the format:
—- —- —- —- —- —-
| x | | x | | a | | b | | c | | d |
—- —- —- —- —- —-
where xs are dummy and abcd 4 bytes are the encryption key.
After the encryption key, data packets are formatted as commands and has a common format:
—-—-—-—-—-
| length of cmd | | pay load |
—-—-—-—-—-
The length has 4 bytes in little endian and describes the number of bytes in payload.
Payload has the following format"
— ———————————-——–——–——
| code | | additional data associated with the code |
—————————————
The code is of course the command code which is of 1 byte, length of data depends on the code.
During handshaking, the commands sent would be:
| key | | 97 | | 00 | | 01 | | 02 | | 03 |
key is the key packet described as above
97 is command 97 which means "Low version"
00 is Protocol Header
01 is Speed
02 is Connection Type
03 is Node Details
Command formats as follows:
97 = Low Version
| 97 |
00 = Protocol Header
| 00 | | minor version (4 bytes LE int) | | major version string |
where the information part of minor version and major version is encrypted using RC4 with key:
[ 0x39, 0x38, 0x37, 0x38, 0x39, 0x61, 0x73, 0x6a ]
01 = Speed
| 01 | | speed (4 bytes LE float, i.e. IEEE 754) |
02 = Connection Type
| 02 | | link type (1 byte) | | is port 0 (1 byte) | | is bad port 0 (1 byte) | | is bbs link (1 byte) |
link type = {Search = 0, Transfer = 1, BBS Search = 2|, others are boolean values
03 = Node Details
| 03 | | ipv4 address (4 bytes BE int) | | port (4 bytes LE int) | | DDNS name length (1 byte) |
| cluster word 1 length (1 byte) | | cluster word 2 length (1 byte) | | cluster word 3 length (1 byte) |
| DDNS | | cluster word 1 | | cluster word 2 | | cluster word 3 |

Winny in Java
Posted on August 10, 2008. Filed under: Java, P2P, Winny |
This summer I finally have the free time that I longed for. I always wanted to investigate Winny which is a Japanese P2P software.
There's some functions that I needed but updates is impossible because the author is caught for making it.
So I think it would be good to create my own Winny compatible P2P client. Here's some screen capture of it.
I uses Berkeley DB JE to store files discovered in the network and have Apache Lucene to index all the file names.
The result is pretty good and Lucene is working amazingly fast, but Berkeley DB JE is a bit slower than I expected..
I am able to search 200k files in about 11s. Query in Lucene takes 1 – 2s, but joining to data in Berkeley DB is unexpectedly slow. Maybe I need to do some more tuning.
By now I have implemented basic connections and queries, and it is now running in Port 0 mode, file downloading (uploading) is yet to come…

I'm published in the latest issue of "Journal of Interactive Learning Research":
The article I co-authored is titled, Civic Participation Among Seventh-Grade Social Studies Students in Multi-User Virtual Environments. Here's our abstract:
Technological advances on the Internet now enable students to develop participation skills in virtual worlds. Similar to controlling a character in a video game, multi-user virtual environments, or MUVEs, allow participants to interact with others in synchronous, online settings. The authors of this study created a link between MUVEs and participation in civic activities by seventh grade students. This purpose of this case study was to evaluate how face-to-face cooperative structures would translate to an online setting. The study also assessed whether working cooperatively in a MUVE would have an effect on student civic participation. The virtual environment did provide an authentic setting for students to practice the civic lessons they learned in class. Student involvement in a participatory culture generally translated to an increased tendency to be civic-minded.

Highview's CryoEnergy System Efficiently Stores Energy With Liquified Air
Posted By Daniel C Jones On March 28, 2011 @ 2:00 pm In clean tech,green technology,Renewable Energy | 2 Comments
One of the major issues with renewable energy technologies like solar and wind power is that energy generation tends to be intermittent — i.e. the sun doesn't always shine and the wind doesn't always blow. Therefore, in order for such technologies to be capable of meeting our needs without the support of fossil fuels, we need to find effective and commercially viable ways to store energy. That's why the guys at Highview Power Storage are getting particularly excited about their most recent technology – the CryoEnergy System (CES). CES takes excess energy generated and uses it to run refrigeration units which cool air down to a temperature of -196C (-320.8F), at which point it liquefies. The liquid air, also known as cryogen, can be stored in an insulated tank, and at times of peak-demand, when the direst output of existing energy sources cannot meet the demands of a power grid, this liquid air is released to generate energy.
Solving the energy storage problem would be a huge step towards emission-free power generation on a global scale. Once Highveiw's CryoEnergy Storage system stores and releases air, the liquid boils, regasifies and expands by up to 700% when heated above -196C (so even room temperature can superheat it). This mega-high-pressured gas is then used to spin turbines which then power a generator.
The only by-product of the CES process is cold air, but what about its efficiency? When exposed to ambient air temperatures, the cryogen gas returns about 50% of the energy used in creating it. But as the amount of stored air increases so does the intensity of the regasification process, resulting in an efficiency of up to 70%. The process is perfect for facilities that generate large volumes of waste heat, as this could boost the efficiency of CES. Furthermore, the cold air produced by the process could even be used for air conditioning, refrigeration or even to create more liquid air. All of this increases the efficiency of the entire process.
When all the criteria for energy storage is taken into consideration, the use of batteries is inferior to CES. While high-efficiency batteries can yield 1 kW of power, they cost about US $4,000 which is 4 times the cost required by CES to produce the same power
A pilot project, fully integrated into the UK's national grid, is currently in operation and is being supported by the Department of Energy & Climate Change and UK-based utility SSE (Scottish & Southern Energy). Highview plans to have a 3.5 megawatt (MW) commercial-scale plant operational by 2012, with the aim of increasing capacity to 10MW by 2014.
In the race to find the innovative energy storage solution that can take our renewable energy ambitions to the next level, CES provides the most efficient, economic and environmentally-friendly answer. So far.

Modeled after the Amber Alert System, this network helps locate wanderers.
Relatives of people with dementia or Alzheimer's disease often have the nagging fear that their loved one might wander away and get lost. It's estimated that more than 9 of 10 people with dementia who leave the house alone are likely to be unable to find their way home without assistance, giving caregivers and other relatives endless moments of anxiety until their loved one is found. The Silver Alert System is designed to provide some reassurance to anxious relatives that their missing seniors can be reunited with them. The Silver Alert is patterned after the Amber Alert system, but instead of missing children this one informs the public about missing seniors with mental impairments.
Silver Alert System: How It Works
On a local level, the Silver Alert System works much like the Amber Alert. The missing person incident is reported to the local police. Personal health information may be necessary, and it should show that the person (age 60 or older) suffers from dementia or is otherwise mentally impaired. Relatives should also provide other details that would help in tracking down the missing senior. After verification, the local police inform the state agency tasked to issue alerts.
A statewide Silver Alert is then issued by the state agency. In many states, it's the Department of Public Safety; in some others, the alert is issued by the State Police, Highway Patrol or Department of Law Enforcement, the State Bureau of Investigation, a State Center for Missing Persons or even the State Attorney General.
Once issued, the alert is displayed on electronic highway signs and broadcast on radio and television. There is one difference, however. In the case of Amber Alerts, alerts of missing children immediately interrupt regularly scheduled programming. As currently implemented in the states that have a Silver Alert System in place, the message does not break into regular programming, but is announced on air only during commercial breaks, which occur every hour or half-hour.
To protect privacy, many states require the personal health information to be deleted once the alert has passed.
Silver Alert System: States Setting The Trend
Silver Alert was started in Colorado in 2006. By the end of 2008, 12 other states had implemented a Silver Alert system: Delaware, Florida, Georgia, Kentucky, Louisiana, Missouri, North Carolina, Ohio, Oklahoma, Rhode Island, Texas and Virginia.
This year, several more states, including Indiana, Michigan, Mississippi, New Hampshire, New Jersey, New York, Pennsylvania, Tennessee and Washington are considering legislation to set up their own Silver Alert programs.
Success rates have been impressive, although not all states have made their specific results available. Georgia has issued 68 Silver Alerts and all the missing seniors were found. There have been 27 alerts in Florida (which ranks second after California as having the highest population of seniors in the US) and all were found, with six being specifically attributed to the alerts.
Silver Alert System: Going National
Legislation has been filed in Congress that would create a national network for Silver Alerts and provide $10 million in federal funding to help states with their programs. The bill, known as the National Silver Alert Act 2009, was approved by the House last February; it is now awaiting action in the Senate.
Many organizations believe the need for Silver Alerts can only increase in coming years. The proportion of elderly in America will expand as the huge Baby Boomer generation moves into retirement range.
Wandering is one of the symptoms of Alzheimer's disease, which currently affects at least 5.2 million Americans. The Alzheimer's Foundation estimates that at least 60 percent of them—3 million people—are likely to wander in the course of their disease. Further statistics indicate that, among people with dementia who wander, at least 50 percent could suffer serious injury or die if they remain missing for more than 24 hours.
Like a missing child, a missing elder can be a family's worst nightmare. Time is of the essence in these situations. The Silver Alert System is one way to help get seniors back before any harm can come to them.

Let $\mathbb{F}$ be a field with $\operatorname{char}(\mathbb{F})=p>0$.
The derivative of a polynomial $P(x)={\displaystyle \sum\limits _{i=0}^{n}a_{i}x^{i}}\in\mathbb{F}[x]$ is $P'(x)=\sum\limits _{i=1}^{n}a_{i}ix^{i-1}\in\mathbb{F}[x]$.
I wish to prove that for $f\in\mathbb{F}[x]$:$f'=0\implies f(x)=g(x^p)$ where $g(x)\in\mathbb{F}[x]$.
I tried going by this definition of the derivative here but all I got was $p\mid ia_i$ for all $i=1,2,..,n$.
Any ideas?

What does mean $p | i a_i$? – Lierre Apr 20 '12 at 18:04
The following tangential comment might interest some readers. The error correction process for the Reed-Solomon codes used in CD and DVD players requires evaluation simultaneous evaluation of $\Lambda(x)$ and $x\Lambda^\prime(x)$ at the $255$-th roots of unity in $\mathbb F_{2^8}$ of characteristic $2$, and takes advantage of the fact that $x\Lambda^\prime(x)=\Lambda_1x+\Lambda_3x^3+\Lambda_5x^5+\cdots$ to save a lot of calculation by arranging the computation of $\Lambda(\alpha)$ to produce $\alpha\Lambda^\prime(\alpha)$ as a side result. – Dilip Sarwate Apr 20 '12 at 18:53

Hint: While technically correct, the notion of divides, i.e. $\mid\;$, is not the best way to phrase things here; instead, since $\operatorname{char}(F)=p$, what you have is $ia_i=0$ for all $i=1,2,\ldots,n$. What does that tell you?
share|improve this answer
$i=0$ or $a_i=0$? – Belgi Apr 20 '12 at 18:10
Exactly! :) $\text{}$ But remember, $i$ is not an element of the field $\mathbb F$, but is just a positive integer, so $i=0$ really only tells you that... – Zev Chonoles Apr 20 '12 at 18:11
With this hint I got that:$a_1=0,...a_{p-1}=0,a_{p+1}=0...$ hence $P(x)=a_px^p+a_{2p}x^{2p}+...$ right? :) – Belgi Apr 20 '12 at 18:16
Well, I should mention that for any $i\geq0$, either $a_i=0$ or $p\mid i$, or both - so it still might be the case that some of the $a_{np}=0$. – Zev Chonoles Apr 20 '12 at 18:23
Thanks for the hint! by the way, can we say something about $x^p$? it's probably not true but does $x^p=x^0=1$? (why?) – Belgi Apr 20 '12 at 18:23
The main point you have to understand here is that the statement $p |ia_i $ doesn't make sense because $p$ is not in $F$ and also there is no reasonable definition of "divisibility" in a field.
The correct thing to say is that $ia_i=\bar i\cdot a_i\in F$, with $\bar i\in \mathbb F_p\subset F$.
Hence if $p$ does not divide $i$ in $\mathbb N$ (where divisibility makes sense!), we have $\bar i\neq 0\in F$ and since $\bar i\cdot a_i=0\in F$ we deduce $a_i=0\in F$.
From this you get $f(x)=g(x^p)$ where $g(y)=\sum_i a_{ip}y^i$.
share|improve this answer
Well, I said that at first too, but $p=\underbrace{1+\cdots+1}_{p\text{ times}}$ still makes sense in $F$, and since $p=0$ in $F$ and $0\mid m$ implies $m=0$ in any ring, $p\mid ia_i$ is still saying that $ia_i=0$ in $F$. But of course, I agree that $\mid$ is not the right thing to use in this situation. – Zev Chonoles Apr 20 '12 at 18:44
Thank you for pointing this out, indeed it sould be written in a different way as you stated. +1 – Belgi Apr 20 '12 at 20:00
Zev note is a good point too as there is a reasonable definition for divisibility in any ring really. – Belgi Apr 20 '12 at 20:01
Dear _USER_, if $1\in \mathbb N$ is the usual Peano integer and if $p=1+...+1\in \mathbb N$ then, no, $p=1+1+...+1$ is not in $F$ because $\mathbb N$ is in no sense included in $F$: for example $F$ might be finite and $\mathbb N$ is infinite. On the other hand it is true that $\bar p=p*1_F=1_F+...+1_F=0_F\in F$ where I have denoted by $*$ the scalar multiplication of an element of $\mathbb Z$ with an element of the $\mathbb Z$-algebra $F$. The sentence you use "p=0 in F" is an abuse of language short-circuiting these precise notations. (To be continued) – Georges Elencwajg Apr 20 '12 at 20:32
(Continued) This is perfectly admissible for people, like you, who know exactly what they mean but beginners should be absolutely precise when confronted with these subtle concepts for the first time. – Georges Elencwajg Apr 20 '12 at 20:33

In order to relieve the lintel from too great a pressure a " discharging arch " is generally built over it.

Rheinmetall Defence unveiled today a new armed reconnaissance mission module for their Mission-Master Autonomous Unmanned Ground Vehicle (A-UGV). The new mission module includes an intelligence-gathering multi-sensor pack and a remotely controlled weapon station. With these systems, Mission Master Armed Recce operators can collect tactical intelligence in an operation area while providing fire support for front-line troops.
The main advantage of operating such an autonomous robotic vehicle is its crewless operation, thus enabling collecting information from high-risk areas, where the robot operates as a scout, without risking human lives. The mission payload is mounted on a 3.5-meter expandable mast with a tilting mechanism enabling the vehicle to use the system on the move or from a defilade to minimize its exposure to the enemy.
The recce payload consists of a staring radar (the configuration implemented in the prototype covers 180º using two ELM-2112 digital staring radars providing persistent surveillance over a wide area. mounted on the mast's tip, the panoramic full ring camera provides additional surveillance covering 360º. A dual EO/IR camera payload investigates suspected objects detected by other sensors, sending targeting information back to the operator. A laser rangefinder and designator help to locate the targets and engage those targets with indirect or direct fires from other platforms. In the current configuration, the vehicle mounts Rheinmetall's own Fieldranger Light 7.62mm weapon station, controlled remotely by a human operator.
The electrically-powered Mission Master platform weighs 1,100 kg, including batteries, carrying up to 600 kg of payload. All Mission Master variants, including the Recce vehicle, can be transported on rail, transporters, and sling loaded under CH-53 or CH-47 helicopters. Rheinmetall has also developed a transportation cage that enables heavy transport helicopters deploying two vehicles on a single airlift. The platform is also amphibious, able to swim at 5 km/h, carrying 300 kg.
Rheinmetall is improving the amphibious capability of the Mission Master, introducing the new amphibious variant by mid-2021. The vehicle can operate for eight hours or travel at 20 km/h over 140-160 km with batteries fully charged. However, in recent operational tests, the vehicles operated for more than 24 hours between charges, as the electrical power draw is rarely at peak levels most of the time. For extended missions, the vehicle can be fitted with a small gasoline engine generator for battery charging.

The robotic vehicle owes its autonomy to Rheinmetall's PATH autonomous vehicle kit designed specifically for military autonomous vehicles. PATH enables users to teleoperate the Mission Master using tablets, smartwatches, or handheld controllers or computers commonly used with soldier systems. These devices enable full access to advanced PATH features such as follow-me, convoy, and autonomous navigation modes. Each control mode incorporates multiple layers of protection to ensure that the vehicle operates safely at all times. The Armed Reconnaissance version is already networked to the Argus soldier system and Rheinmetall Command and Control Software, installed in any user's battle management system. For autonomous navigation, the system relies on artificial intelligence and machine learning to learn the terrain and topography of the operation area (urban, desert, woodland), thus improving the ability to reason and understand objects, obstacles, and movement strategies.
The vehicle features a radio-agnostic architecture, enabling users to integrate their radio of choice to meet their sovereign communications systems. The radio enables the Mission Master operator and the robot to conduct bi-directional communications, enabling remote control, communicating with other robots, and a higher command post.
While the operator controls the robot from a distance and receives the scout information, the robot can conduct autonomous navigation and movement and autonomously perform some of the surveillance tasks according to the mission planning. On the mission package, AI is also employed to improve surveillance, detect changes, follow different behaviors of objects and tracks, to assess or determine intentions. Some of these reconnaissance and surveillance functions are already developed and tested (TRL-8), while remote weapon station autonomy (not including actual firing) still under development (TRL-6). As to autonomous weapon firing, Rheinmetall emphasized it is committed to keeping a man in the loop in all kinetic operations, assuring that a human decides when to open fire, never a machine.
Power of the Wolf Pack
This autonomy level takes the mission master a step closer to Rheinmetall's fully autonomous 'Wolfpack' concept, where a squad of robots commanded by a single human operator is ready to perform combat missions.
The Wolf Pack consists of multiple Mission Master vehicles operating as a team to perform specific missions such as zone surveillance, reconnaissance, or perform specific team tasks – target position transfer or multi-platform slew-to-cue. To accomplish such teamwork with all units, communicate with each other, and use artificial intelligence to maintain the total situational awareness necessary for carrying out their missions.
The Wolfpack differs from the Wingman concept pursued by the US and Australian military, in its focus on mission autonomy. While the Wingman comprises one or two vehicles closely controlled by a human operator to form a combat team, the Wolfpack leverages a group of 2-6 robots 'herded' by a single operator from a remote command post or command vehicle. Therefore, a single operator can manage the entire Wolf Pack from anywhere, using the LTE network, SATCOM, or a military cloud. It is an intuitive concept that enables one operator – rather than a crew or multiple uncoordinated operators – to focus on the overall mission rather than managing all the tasks of each A-UGV. In the prototyping phase (TRL-6), Rheinmetall plans to demonstrate the concept within a year.
The new Armed Reconnaissance module is the latest addition to the modular Mission Master family, widely acclaimed for its all-terrain maneuverability and ability to keep troops safe when deployed in harm's way. The Cargo module can carry over half a ton of supplies, relieving troops' burden keeping them fresh. The Fire Support modules boost dismounted units' combat power, while the Rescue module autonomously evacuates casualties and carries specialized equipment for medical interventions in the field. Also, every single module is equipped with a Blue Force tracking system that is fully compatible with NATO standards.

Just installed a new battery from Anker. This tutorial was very helpful to me. iFixit was out of stock on the battery I needed, or I would have ordered from you.
Anker did include the special 5 prong tiny screwdriver needed.

Ordered the battery from iFixit, forgot to order the Pentalobe screwdriver. Nevermind, if you only do that stuff once (as I expect after 6 years with one battery) - don't spend the money on special equipment that cannot be used for anything else :)
Opening the macbook is easy (I have done that before to exchange the superdrive with a larger harddisk and the original HD with an SSD drive, and a couple of times to clean the fans), but the 3 screws on the battery are a pain.
What did the job for me: an old mini-flathead-screwdriver (approx. 2mm? - just slightly larger than the pentalobe) and a file. As none of my other screwdrivers would work with the ....pentalobes, i filed down the flathead (-)screwdriver so that it could get hold in 2 of the lobes - which did let me open and close these screws without a problem. My screws were not closed very tight though - if they are there is probably no way around the right tool.

Hello , I just replaced the battery on my macbook pro 15 inch 2009. Original battery was dead, would not even start without being plugged in.
I replaced the battery myself with one from amazon. Lizone is the brand. Laptop powers on now without being plugged in but after I enter my password it turns off, right after the login screen. Doesnt matter if its plugged in or not. I can access the login screen and thats it. When I removed the battery the laptop starts normal and I can get past the login screen and into el capitan.
I reseted SMC and PRAM multiple times. Is it a faulty battery ? What can I try?

Meaning: highland; The name Elam is an Assyrian word meaning "high."
the son of Shem (Gen. 10:22), and the name of the country inhabited by his descendants (14:1, 9; Isa. 11:11; 21:2, etc.) lying to the east of Babylonia, and extending to the shore of the Mediterranean, a distance in a direct line of about 1,000 miles
"The inhabitants of Elam, or 'the Highlands,' to the east of Babylon, were called Elamites. They were divided into several branches, speaking different dialects of the same agglutinative language. The race to which they belonged was brachycephalic, or short-headed, like the pre-Semitic Sumerians of Babylonia.
"The earliest Elamite kingdom seems to have been that of Anzan, the exact site of which is uncertain; but in the time of Abraham, Shushan or Susa appears to have already become the capital of the country. Babylonia was frequently invaded by the Elamite kings, who at times asserted their supremacy over it (as in the case of Chedorlaomer, the Kudur-Lagamar, or 'servant of the goddess Lagamar,' of the cuneiform texts).
"The later Assyrian monarchs made several campaigns against Elam, and finally Assur-bani-pal (about B.C. 650) succeeded in conquering the country, which was ravaged with fire and sword. On the fall of the Assyrian Empire, Elam passed into the hands of the Persians" (A.H. Sayce).
This country was called by the Greeks Cissia or Susiana.

From truth to "dark legend"
The two Anatomical Machines are among the most enigmatic exhibits in the monumental complex. Even today, over two hundred and fifty years later, the debate continues on the procedures and materials used to obtain such excellent preservation of the circulatory apparatus. Nourishing the "dark legend" of Raimondo di Sangro, the Breve nota referred to "injection", suggesting that, under the Prince's direction, Salerno had injected a substance into the blood vessels of two bodies in order to cause their "metalisation".
Benedetto Croce too recounts that, according to popular belief, Raimondo di Sangro "had two of his servants killed, a man and a woman, and had the bodies strangely embalmed so that they showed all the viscera, the arteries and the veins". In reality, the circulatory system is the result of a reconstruction carried out using different materials including beeswax and colourants. What is surprising, however, is the reproduction of the arteriovenous system down to even the finest vessels, showing such incredibly advanced anatomical knowledge for the time, that a research group have recently suggested that experiments with injections had been performed prior to reconstruction.


Using the VEMCO Positioning System (VPS) to explore fine-scale movements of aquatic species: applications, analytical approaches and future directions
Danielle L. Orrell, University of Windsor
Nigel E. Hussey, University of Windsor
Abstract
Recent advancements in telemetry have redefined our ability to quantify the fine-scale movements of aquatic animals and derive a mechanistic understanding of movement behaviours. The VEMCO Positioning System (VPS) is a fine-scale commercial positioning system used to generate highly accurate semi-continuous animal tracks. To date, VPS has been used to study 86 species, spanning 25 taxonomic orders. It has provided fine-scale movement data for critical life stages, from tracking day-old turtle hatchlings on their first foray into the sea to adult fish returning to natal rivers to spawn. These high-resolution tracking data have improved our understanding of the movements of species across environmental gradients within rivers, estuaries and oceans, including species of conservation concern and commercial value. Existing VPS applications range from quantifying spatio-temporal aspects of animal space use and key aspects of ecology, such as rate of movement and resource use, to higher-order processes such as interactions among individuals and species. Analytical approaches have seen a move towards techniques that incorporate error frameworks such as autocorrelated kernel density estimators for home range calculations. VPS technology has the potential to bridge gaps in our fundamental understanding of fine-scale ecological and physiological processes for single and multi-species studies under natural conditions. Through a systematic review of the VPS literature, we focus on 4 principle topics: the diversity of species studied, current ecological and ecophysiological applications and data analysis techniques, and we highlight future frontiers of exploration.

A New Cable-Truss Structure for Roadway Driving Next to Goaf
- 63 Downloads
The roof deformation and damage of roadway driving next to goaf in the vertical and horizontal directions are serious, the process of horizontal squeezing–expansion is difficult to be controlled using the traditional anchor truss structure. To solve this problem, a new type of cable-truss structure was designed to effectively control the deformation and damage of the roof along the vertical and horizontal directions. Besides, it had the function of horizontal bidirectional constant resistance. The mechanism of the structure is explained first. Then, the basic mechanical properties obtained through laboratory tests are presented. Finally, field practice is discussed. The results show that the new cable-truss structure has a load bearing force acting on its combination beam according to the horizontal movement of roadway roof. It can also adjust its length to prevent or adapt to the horizontal squeezing-expansion movement of roof, which ensures that the combination beam will not be distorted, torn, or broken. Thus, this new cable-truss structure can effectively mitigate the roof-caving accidents.

HONG KONG (Reuters) - A gene that raises rice yields by enhancing root growth and nutrient absorption in low quality soils has been identified in a species of rice in India and successfully introduced into other rice varieties, researchers reported on Thursday.
Scientists and rice breeders have known for years that Kasalath rice is unusually efficient at nutrient absorption, but only now have they succeeded in identifying the gene responsible for this important trait.
In a paper published in the journal Nature, they described how they identified the gene after analyzing part of the Kasalath DNA where it was thought to be located and comparing it with other rice varieties without the trait.
Using conventional breeding methods, they introduced the gene into a few rice types in Indonesia, the Philippines and Japan and found that it raised yields by up to 20 percent.
"We found a gene that enhances phosphorus uptake in low phosphorus conditions. We have been looking for it for many years," said lead author Sigrid Heuer at the International Rice Research Institute in Manila.
Heuer said the superior breeding lines could be released to farmers in Indonesia in about 2-3 years. These have already been developed using conventional breeding methods -- by pollinating the flowers of a native Indonesian rice species with pollen from the Kasalath.
"As for other Asian countries, we will get them to put the gene into their local varieties through conventional breeding," said Heuer, adding that this would take about 4-5 years.
By using conventional breeding techniques, in this case, cross-pollination, there are no issues related to genetic modification. Food safety concerns and regulatory hurdles for transgenic rice -- where a gene is physically inserted into plant DNA in a laboratory -- can translate into years or even decades of testing before the strain reaches markets
The gene, PSTOL1, allows rice crops to thrive in soil that has low levels of phosphorus, a nutrient that promotes root growth, winter hardiness and hastens maturity. Plants deficient in phosphorus are often stunted.
"Fifty percent of world's arable land is too low in phosphorus. It's not like if you have this gene that the plants don't need phosphorus anymore," said Heuer.
"They (rice plants with the gene) may be able to exploit the soil a little better so the harvest is better. They may make better use of fertilizer because they can take it up more efficiently... If you have a bigger root system, then the plant can take it up better and they can have better access to the patches where the phosphorus is."

Background: Heart rate (HR) reduction is essential to achieve optimal image quality and diagnostic accuracy with computed tomography coronary angiography (CTCA). Administration of oral ivabradine seems to be more effective than beta-blockade in reducing HR in patients referred for CTCA. Methods: Two-hundred-fifty-nine consecutive patients referred for CTCA were prospectively enrolled. Patients not receiving beta-blocker at baseline (group 1) and those with beta-blocker therapy (group 2) were enrolled in the study. Each group was randomized into 3 parallel arms with 1:1:1 allocation. Patients who did not receive beta-blocker at baseline: underwent CTCA without beta blocker (n = 49), and received ivabradine 5 mg (n = 48), or 7.5 mg ivabradine (n = 48). Patients with beta-blocker therapy: continued with the prior beta-blocker without any dose modification (n = 38), and received ivabradine 5 mg (n = 38), or ivabradine 7.5 mg (n = 38). Results: HR and blood pressure were assessed at admission (T0), immediately before CTCA (T1) and during CTCA (T2). Administration of ivabradine 7.5 mg significantly reduced mean relative HR at T1 and T2 (p < 0.01), the rate of patients not achieving target HR at T1 (p < 0.001) and T2 (p < 0.01), and the percentage of patients needing additional IV beta-blockade prior to CTCA (p < 0.01). Results remained statistically significant even after correction for age, gender, ejection fraction, risk factors and HR at T0, in a multivariable analysis. Conclusions: Ivabradine 7.5 mg is more effective than ivabradine 5 mg in increasing the rate of patients at target HR in patients referred for CTCA.

Design Optimization Using Lookup Table Requirements for Gain Scheduling (GUI)
This example shows how to tune parameters in a lookup table in a model that uses gain scheduling to adjust the controller's response to a plant that varies. Model tuning uses the Response Optimizer app.
Ship Steering Model
Open the Simulink® model.
This model implements the Nomoto model which is commonly used for ship steering. The dynamic characteristics of a ship vary significantly with factors such as the ship speed. Therefore the rudder controller should also vary with speed, in order to meet requirements for steering the ship.
To keep the ship on course, a control loop compares the ship's heading angle with the reference heading angle, and a PD controller sends command signals to the rudder. The Ship Plant block implements the Nomoto model, a second order system whose parameters vary with the ship's speed. The ship is initially traveling at its maximum speed of 15 m/s, but it will slow down when the reference trajectory specifies a turn in the water. This turning, along with the force of the engine, is used by the Force Dynamics block to compute the speed of the ship over time. The Kinematics block computes the trajectory of the ship.
Open the Controller block by double clicking it.
When the speed changes, the ship plant also changes. Therefore the PD controller gains need to change, and speed is used as the scheduling variable. The controller is in the form
K(1 + sTd) where
K is the overall gain and
Td is the time constant associated with the derivative term. Gain scheduling is implemented using lookup tables, and the table data are specified by
Td. These are vectors which specify different values for different speeds. The different speeds are specified in the lookup table breakpoint vectors
The reference specifies that at 200 seconds, the ship should turn 180 degrees and reverse course. One requirement is that the ship heading angle needs to match the reference heading angle within an envelope. For the safety and comfort of passengers, a second requirement is that the total acceleration of the ship needs to stay within a bound of 0.25 g's, where 1 g is the acceleration of gravity at Earth's surface, 9.8 m/s^2.
The controller parameter vectors
Td will be design variables, and will be tuned to try to meet the requirements. If it is not possible to meet both requirements, then the lookup table breakpoints
bpTd will also be used as design variables. In that case, we will need to specify an additional requirement that
bpTd must be monotonically strictly increasing, because this is required for breakpoint vectors in Simulink lookup tables.
Open the Response Optimizer
In the Apps tab, click Response Optimizer under Control Systems.
Specify Design Requirements
Specify the requirements which must be satisfied. First, the ship should follow the reference trajectory. Since the reference is essentially a step change from 0 to 180 degrees, you specify a step response envelope for the ship heading angle. In the toolstrip, click New and select Step Response Envelope. Set the initial value to 0 and the final value to pi radians. Set the step time to 200 seconds. Set the rise time as 75 seconds and the rise percent to 85%. Set the settling time to 200 seconds and the settling percent to 1%. Set the percent overshoot to 5%. To specify that this requirement applies to the ship heading, click +.
In the Simulink model click the ship heading signal, which is the output of the Ship Plant block. Select this signal in the Create Signal Set dialog, and click the arrow button to make it the designated signal, and click OK.
The second requirement is that for the safety and comfort of passengers, the total acceleration should not exceed 0.25 g's at any time. The total acceleration is composed of two components, a tangential component along the direction of the ship's motion, and a normal (horizontal) component. The requirement that total acceleration not exceed 0.25 g's corresponds to requiring that in the phase plane of tangential and normal acceleration, this ship's trajectory remain within a circle of radius 0.25*9.8.
In the toolstrip, click New and select Ellipse Region Constraint. Specify the name as
SafeAccel, and the semi-axis length for both signals as 0.25*9.8 = 2.45. To specify that the requirement applies to the tangential acceleration of the ship, click the Select button. In the Simulink model click the tangential acceleration signal, which is output from the Kinematics block. Select this signal in the Create Signal Set dialog, and click the arrow button to make it the designated signal, and click OK. Similarly, to specify that the requirement applies to the normal acceleration of the ship, in the Ellipse Region Constraint dialog click the other Select button, and use the Create Signal Set dialog to specify the normal acceleration signal.
Specify Design Variables
Specify the design variables to be tuned by the optimization in order to satisfy the requirements. In the toolstrip, click the selection box next to Design Variables Set and then click New. Select the gains of the PD controller,
Td, and click the arrow button to designate them as design variables. Use -0.1 for all entries in the value of the
K vector, and use 50 for all entries in the value of the
Td vector, and click OK. If the requirements can't all be satisfied, then later the breakpoint vectors
bpTd can also be tried as design variables.
Optimize Lookup Table Data
During optimization, the Simulink solver may generate a warning if the size of the time step becomes too small. Temporarily suppress this warning.
warnState = warning('query', 'Simulink:Engine:SolverMinStepSizeWarn'); warning('off', 'Simulink:Engine:SolverMinStepSizeWarn');
In the Response Optimizer, click Optimize. The ship heading angle does not meet the required step response envelope, as can be seen in the step response plot in the Response Optimizer app and in the Optimization Progress dialog, where the value at the last iteration is still positive, which indicates violation of the requirement. The requirement for safe acceleration is also not met, as seen in the Optimization Progress dialog, where the value at the last iteration is also positive.
Optimize Lookup Table Data and Breakpoints
To try to meet the design requirements, use the optimization result from above as the start point, and tune additional variables. Add breakpoints
bpTd as design variables. The ship's maximum speed is 15 m/s, and during turning it may slow to 60% of the maximum speed, or 9 m/s. Set the breakpoint initial values to be equally spaced between 9 and 15 m/s. Constrain the breakpoint minimum values to 9 m/s, and constrain the breakpoint maximum values to 15 m/s.
Breakpoints in the Simulink lookup table block must be strictly monotonically increasing. Add this to the design requirements.
In the Response Optimizer, click Optimize. This time the ship heading angle meets the required step response envelope, as can be seen in the step response plot in Response Optimizer app and in the Optimization Progress dialog, where the value at the last iteration is negative, which indicates the requirement is satisfied. The requirement for safe acceleration is also satisfied, as seen in the Optimization Progress dialog, where the value at the last iteration is also negative. Similarly, the lookup table breakpoints satisfy the monotonic requirements.
In this example, the ship plant varied with the ship speed, so the controller gains also needed to vary. Gain scheduling was implemented using lookup tables. By tuning the gains and breakpoint values in the controller, the ship was able to follow the reference heading angle, while also constraining total acceleration to ensure a safe and comfortable ride for passengers.
To learn how to optimize the lookup tables in the gain scheduled controller using the
sdo.optimize command, see Design Optimization Using Lookup Table Requirements for Gain Scheduling (Code).

IUCN Status: Least concern
Our family of Gelada baboons at Howletts share their large open topped enclosure, near the Gatehouse, with our group of black and white colobus monkeys. Whilst they live together in relative harmony, occasionally a young gelada, full of mischief, will pull the colobus' tails and run away, which obviously causes a bit of an uproar!
Want To Know More
Whilst referred to as a baboon, geladas are actually the last surviving species of a once widespread group of grass grazing primates.
In the wild geladas can only be found on the rocky highland escarpments of Northern Ethiopia. By night they sleep on rocky outcrops and during the day, they graze on the lush grasslands.

How do you make greek cypriot coffee?
- Pour 1 espresso sized cup of water into a "brike". If you do not have a "brike" you can use a small pot.
- Place on a hot (i.e. the temperature you would use to bring water to a boil) stove
- Begin to bring the coffee to a boil
- Pour into your cup, let sit for 2 minutes and enjoy!
What is the difference between Greek coffee and regular coffee?
The process of boiling extracts more nutrients from the coffee beans. Furthermore, Greek coffee is comprised of Arabica coffee beans ground to a very fine powder. In this way, Greek coffee delivers more concentrated antioxidants than a normal cup of coffee, and it contains only a moderate amount of caffeine.
What is the optional ingredient to make a cup of Greek coffee?
a briki. a small coffee cup, about the size of a large espresso cup. greek coffee grounds sugar (optional).
What is special about Greek coffee?
Greek coffee is a strong brew of coffee, which is served with foam on the top (kaimaki) and the grounds at the bottom of the cup It is a style of coffee prepared using very finely ground coffee beans without filtering.
Is espresso the same as Greek coffee?
Greek coffee drinks require extremely fine coffee granules, which is sometimes called a turkish grind. These grounds are essentially powdered, almost the same texture as espresso powder, but they're not the same thing.
What is the difference between Turkish and Greek coffee?
If you order sweetened coffee turkey, it's traditionally brewed with sugar right in the cezve, while in Greece and in Arab countries, sugar's added afterward Arabic-style coffees also may get spiced with cardamom or cinnamon, which less less common in Turkey and Greece.
Why is my Greek coffee Grainy?
Practically speaking, this is because Greek coffee is prepared by boiling the coffee grounds which then settle to the bottom of the demi-tasse cup in which the coffee is served. Drink too quickly and these grounds may accidentally end up in your mouth (gritty and a bit gross).
What is Cypriot coffee?
Cyprus coffee is unique and unlike most types of coffee served in Europe. The Cyprus coffee is brewed in small, long handled pots, called "mbrikia" and those were traditionally made of copper. In addition, the Cypriot coffee is made from fresh coffee beans Brazilian.
What kind of coffee beans are used for Greek coffee?
Greek coffee is made from Arabica coffee beans , which are ground to a very fine powder (much finer than the coffee grinds in many other countries around the world). The coffee in Greece is similar to that in Turkey and throughout the Middle East.
What kind of coffee do they drink in Greece?
The Ibrik Or "Greek" Coffee Greek coffee, also known as "ibrik coffee" has been around – and remained popular – for centuries. It is finely ground coffee made and served from a "briki", also known as an "ibrik" (a small brass pot with a long handle).
Is Greek coffee healthier than American coffee?
The combination of boiling a fine grind gives Greek coffee a powerful, one-two health punch. Plus, you get less caffeine than in an American cup of coffee , so ounce for ounce it's a healthier choice.
What is Greek coffee called in Greek?
In Greek, this is called glykos or γλυκός and pronounced ghlee-KOHSS. For extra-strong sweet coffee, add 3 teaspoons of sugar and 2 heaping teaspoons of coffee to the briki and stir.
Is Greek coffee the healthiest?
According to many studies, Greek coffee can reduce the risk of premature death For instance, experts found that people on the island of Ikaria, who drink boiled Greek coffee at least once per day, have better cardiovascular health compared to others, with most locals living beyond 90 years of age.
Does Greek coffee have Cardamom?
Sharing is caring! This deep, rich, Turkish Coffee Recipe, is also known as Greek Coffee and Arab Coffee. The espresso used to make this Turkish coffee recipe is blended with ground cardamon , which gives this coffee its wonderful flavor.

Education Law
 School political activity
 Political activity on school property: What legal restrictions apply?
 As the election approaches, questions arise in many school districts about what political activity is permissible on school property. Can staff distribute campaign flyers on school grounds? Can the levy committee post pro-levy signs on school grounds? Can a school board member running for re-election solicit campaign contributions from employees at school? Can students wear campaign attire at school? The legal rules are complex and vary depending on whether staff, students or outside groups are involved. This article provides a brief, general overview of the law governing political activity on school property to help guide your analysis of situations that may arise.
 Legal restrictions on campaign activity by school employees and officials
 Public school employees have First Amendment rights to engage in campaign activity on their own time as private individuals. They do not have the same freedom to engage in campaign activity at school.
 Ohio law prohibits public boards of education from compensating any employee for "time spent on any activity to influence the outcome of an election" regarding a candidate for public office or the passage of a levy or bond issue or other ballot issue. [1] It is not always easy to determine what constitutes activity to influence the outcome of an election, but that would certainly include handing out campaign flyers that advocate for or against a candidate or ballot issue, urging colleagues to vote for a candidate or issue, and preparing campaign mailings. Accordingly, public school employees cannot engage in such campaign activity on paid time, including paid time after the school day (e.g., while working as a coach or club advisor). Board policy may also restrict political activity such as distribution of campaign literature. If so, that policy must be enforced even-handedly.
 It is not yet clear whether the wearing of campaign buttons during instructional time constitutes prohibited campaign activity under Ohio law, but it may be prohibited under board policy. Boards of education have the authority to ban attire containing political messages during the school day, without regard to the content of the message being conveyed. This type of viewpoint-neutral regulation has been held not to violate the First Amendment. [2]
 A teacher's expression of personal views about a candidate or issue during instructional time is problematic because of the perception created that the school endorses the message, as well as the fact that the teacher is being compensated by the board during that time. Teachers may, however, discuss political issues and candidates in a viewpoint-neutral manner, if the discussion is part of an instructional activity and there is a legitimate pedagogical reason for it.
 What if a board member running for re-election wants to solicit campaign contributions from employees on school grounds during the school day? Ohio law prohibits solicitations of contributions from a public employee while the public employee is performing official duties or in areas of a public building where official business is transacted or conducted. [3] In addition, even if the board member promised not to solicit campaign contributions, coming onto school grounds to campaign in any manner during the school day may violate board policies regulating visitor access to school buildings or political activity on school grounds.
 Use of school premises by staff and outside groups
 If a candidate's campaign committee or the school levy committee wants to hold a meeting in a school building, is that allowed? Yes, under certain conditions and in accordance with the requirements of the school board's policy regarding use of school facilities (which typically requires payment of a reasonable fee).
 Boards of education are required to permit the use of premises on a viewpoint-neutral basis for purposes, including educational and civic meetings and other purposes that promote the welfare of the community, as long as the meetings are open to the general public and take place during non-school hours. [4]
 What if a candidate wants to put up signs on school grounds? Many boards of education forbid the posting of signs on school grounds as a matter of policy. If your board has not addressed the issue, then you should bear in mind that any access you decide to permit must be viewpoint neutral. In other words, if you allow pro-levy signs on school grounds, then you must also allow anti-levy signs; if you allow a board member running for re-election to post signs, then you must also allow the opponent's signs.
 What if a school employee wants to copy levy campaign flyers while on a break? Ohio law forbids the use of public funds and resources on campaign activity, including activity in connection with a levy or bond issue. [5] Even the minimal amount of resources involved when sending or receiving an email is prohibited. This means that school employees cannot use their district e-mail accounts for campaign activity. Likewise, school employees cannot use other school equipment, such as school copiers, for campaign activity free of charge. This prohibition applies regardless of the nature of the campaign activity – even if a school employee who serves on the levy committee is making copies of levy campaign literature or using school resources to make pro-levy signs. If board policy permits outside groups to use school equipment upon payment of a reasonable fee, however, then school employees may do the same.
 Student political activity
 Can students wear political buttons to school? The law governing political speech by students is more expansive than the law governing school staff, usually permitting such speech to occur.
 The general rule established by the United States Supreme Court dates back to the Tinker case in which the Court overturned a school regulation banning the wearing of a black armband in protest of the Vietnam war. [6] The Supreme Court held that a school's regulation of any form of speech or expressive conduct violates the First Amendment unless the school reasonably believes that the speech will "substantially and materially interfere" with schoolwork or discipline. A school cannot prohibit student speech merely to avoid controversy or the expression of an unpopular viewpoint.
 Notwithstanding the general rule, schools can prohibit speech that is vulgar, lewd, indecent or plainly offensive. [7] Boards of education may also adopt reasonable, viewpoint-neutral dress code regulations. For example, some boards have banned all attire containing any type of message, regardless of the message. Otherwise, however, it is generally permissible for students to come to school wearing campaign buttons or t-shirts.
 Must a student be allowed to hand out campaign leaflets in hallways if it is affecting traffic flow between classes and causing disorder? No. Schools are generally permitted to enforce reasonable, content-neutral time, place and manner restrictions on speech. For example, an Ohio federal court upheld a school regulation that required a student to post his leaflets on bulletin boards and distribute them during lunch rather than handing them out in the hallways. [8] Any such regulation has to be enforced even-handedly, however, without regard to view being espoused by the student.
 Can a school exercise control over students' political speech in the student newspaper? Yes, to some extent, since the views expressed in the newspaper might be perceived as having been approved by the school. The United States Supreme Court has held that schools have some authority to edit the content of student speech in school-sponsored publications, "so long as their actions are reasonably related to legitimate pedagogical concerns." [9] In other words, a school can regulate student political speech if it is deemed to be inconsistent with the school's educational mission.

Labour market information tells you about the workplace or labour market. Labour market information describes the condition of the labour market, past and present, as well as future projections. It makes clear where work opportunities are increasing or decreasing, what occupations exist, what you need to study to become a professional in that occupation, what is required to take up an occupation, how one can find a job, change job or progress in a career.
And what about labour market intelligence? Labour market intelligence refers to labour market information that has been analysed and interpreted before presenting it to the public. Essentially most careers information is labour market intelligence. In this toolkit we use the notion of labour market information referring to both labour market information and labour market intelligence.
You can discover the definition of labour market information for lifelong guidance here:
DEFINITION OF LMI FOR LIFELONG GUIDANCE
The labour market information for lifelong guidance is defined as information about the following items:
- Labour market profile and trends including employment, unemployment and earnings outlooks by sector, occupation. Data should be available at a national, regional and local dimension where statistically reliable information and non-disclosive data are available. Basic principles of labour market regulation, laws and labour market policies.
- Trends in skills, including skills needs and mismatches, skills gaps, together with current and future skill demands. The regional and local dimension should be included if statistically reliable and non-disclosive information is available.
- Information on occupations including information on skills requirements, educational background, interests, working conditions, skills shortages, pay and earnings.
- Entry and progressions routes into and through occupations including job vacancies
- Entry and progression routes in education and training in order to gain skills for an occupation, or bridge a skills gap for a desired occupation.
- Career planning information on where to find information and assistance
- Equal opportunities and diversity issues (support measures), and changing workforce profile
What is good labour market information?
The quality standards for labour market information should be high because labour market information has many dimensions (as was shown in the definition) and is not easy to work with. You can find the quality criteria for labour market information for lifelong guidance here.
What is good labour market information for lifelong guidance?
High quality labour market information should have the following characteristics:
- Accuracy (eg statistically reliable)
- Completeness eg in terms of sectors, regions
- Timeliness: recent data, frequently updated
- Relevance to user needs and adapted needs of different user groups
- Attractive and available in different formats (i.e. pictures, infographics, tables, charts, graphs and videos)
- Accessibility: taking into account different capabilities and backgrounds, easy to understand text, access without registration, at low cost or free of charge as much as possible, plus available in electronic and hard copy
- Impartial: the information provided is in accordance with the user's interest only, is not influenced by provider, institutional and funding interests, and does not discriminate on the basis of gender, age, ethnicity, social class, qualifications, ability.
- Have authority
- Comparability of data over time, over different geographical levels
- Include local or regional information in order to show the possibilities in the region where one lives but at the same time in other regions (can encourages mobility)
- Transparent: sources of data are indicated
- Be easy to update
- Forward looking
Some specific points of attention are the following:
- Individuals users expect attractive labour market information. It is important that the labour market information is presented in a visually appealing way in websites, infographs, online tools, brochures, …Moreover, the LMI should be presented in different ways in order to meet different information needs and learning styles (and abilities) of clients. In addition to this, users like to try things out, to experiment, to do something, to have access to inspiring activities at employer's premises.
- In your work, it can be challenge to find a balance between providing neutral and objective career advice based on impartial labour market information and the aim and strategy of the organization you are working for.
- Example 1: career guidance and education by a sector federation is focussing on only one sector whereas opportunities usually exist in a number of sectors;
- Example 2: employment counsellors in public employment services may be forced to seek a balance between case load objectives and fast activation targets on one hand and individual preferences or untapped potential of jobseekers on the other hand.
- Example 3: there is a risk for biased or selective information in brochures promoting educational programmes
- Labour market information can be acquired formally and informally. Formal labour market information is spread over many different sources. There is a wealth of labour market information available online in websites, databases, apps, social media, video's, ….. More specific information on ICT and LMI can be found here
The complexity of labour market information requires good navigation skills. For many clients, it is necessary that career practitioners play a role as an interface between labour market information sources and the clients. Career practitioners adapt, interpret, repack labour market information and use it in to educate, inform, advice and guide clients. How can you do this? Learn more about integration of LMI in lifelong guidance in the next chapter

Battle of Yeosu
Part of Korean Conflict
Date 17 – 18 December 1998
Location off the coast of Yeosu, Jeollanam-do, South Korea
Result South Korean victory
 Republic of Korea Navy Korean People's Navy
12 warships,
3 bombers
1 semi-submersible
Casualties and losses
none 1 semi-submersible sunk
~4 dead
The Battle of Yeosu, in December 1998, was a naval skirmish that began when the Republic of Korea Navy intercepted a North Korean semi-submersible vessel attempting to land commandos on the southern South Korean coast.
Throughout 1998 there had been several incidents involving North Korean infiltrators attempting to land on along the South Korean coastline. In the June 1998 Sokcho submarine incident a North Korean submarine was found in South Korean waters off Sokcho entangled in fishing nets, the submarine was towed to a ROK Navy base and when opened the crew were all dead in an apparent murder-suicide. Another infiltration occurred in July when a dead commando and abandoned infiltration craft was discovered near the city of Donghae. [1]
On December 17, a ten ton North Korean I-SILC class semi-submersible infiltration vessel was observed by a South Korean guard post about 2km off the coast of Yeosu and ROK Navy ships were scrambled to intercept it. After several warnings were given, the ROK Navy fired warning shots at the semi-submersible. The North Korean craft ignored the warnings and opened fire on the South Korean vessels. It then attempted to escape, fleeing southwest while being tracked by patrol planes and boats, but several hours later it had sunk in 300 feet (91 m) of water approximately 100km south of Geojedo. [2][3]
The ROK Navy attempted to recover the bodies of the dead North Koreans and pieces of the infiltration craft. The body of one North Korean frogman was found. From the size and type of the vessel it was assumed that the entire crew consisted of four sailors and that all had perished. Searches were also conducted on nearby land to make sure that infiltrators had not landed on the coastline. When questioned, the North Korean government denied sending the vessel or knowing anything about its origins. This incident helped fuel increasing tensions between the two governments and an even larger naval skirmish was fought the next year.
The (North) Korean Central News Agency said on 19 December:
The South Korean puppets said that they located a "submarine" in the sea off Ryosu, South Jolla Province, at 11:15 p.m. on December 17 and had a battle in which the "submarine" was sunken and they brought a dead body clad in diving-suit to the land. They also said that they issued an order called "Jindogae nN.1" throughout the coastal areas of South Korea and have been put on the red alert. This time, too, the puppets described the "incident" as the "intrusion by the north," shifting the blame on to the north. This frantic anti-communist campaign is a continuation of the anti-communist, anti-north campaign such as the fiction of the "intrusion of the north's vessel" near the coast of the Kanghwa island on the West Sea of Korea and the description of a flock of birds as "something mysterious" in the sea off the Kanghwa island. The incidents have nothing to do with the north. Now the South Korean are trying hard to find a pretext for unleashing a war against the north in line with the U.S. imperialists' moves for war against the DPRK. It goes without saying that the "north's submarine infiltration incident" is a farce cooked up for that purpose. We can no longer remain a passive onlooker to the South Korean continuous anti-communist campaign and slander against the north. The campaign can convince no one. We will take resolute measures so that the provokers may drink a bitter cup. We seriously warn the South Korean not to act rashly.

The investment in an automated fabric defect detection system is more than economical when reduction in labor cost and associated benefits are considered. The development of a fully automated web inspection system requires robust and efficient fabric defect detection algorithms. The inspection of real fabric defects is particularly challenging due to the large number of fabric defect classes, which are characterized by their vagueness and ambiguity. Numerous techniques have been developed to detect fabric defects and the purpose of this paper is to categorize and/or describe these algorithms. This paper attempts to present the first survey on fabric defect detection techniques presented in about 160 references. Categorization of fabric defect detection techniques is useful in evaluating the qualities of identified features. The characterization of real fabric surfaces using their structure and primitive set has not yet been successful. Therefore, on the basis of the nature of features from the fabric surfaces, the proposed approaches have been characterized into three categories; statistical, spectral and model-based. In order to evaluate the state-of-the-art, the limitations of several promising techniques are identified and performances are analyzed in the context of their demonstrated results and intended application. The conclusions from this paper also suggest that the combination of statistical, spectral and model-based approaches can give better results than any single approach, and is suggested for further research.

During this mission the Soviets drilled 2 meters into the lunar surface and extracted 300 grams of rock then returned to Earth. This was an impressive feat for its time. Analysis showed the rock was made up of 0.1 percent water. This result was published in 1978 to the Russian journal Geokhimiia. There was an English version but wasn't widely read in the West."
