The Open Data Platform
The core R&D component for Open Data at FOKUS, the Open Data Platform (ODP) is an open source solution that is customizable depending upon an organization's specific requirements.
The ODP is an integrated open source software solution for public agencies and private institutions that make their data available as Open Data, i.e., publishing it according to Open Data principles. The ODP was designed and developed within the EU Open Cities project to enable participating cities to publish their data.
The Open Data Lifecycle
The ODP supports the entire Open Data lifecycle process, which includes identifying, publishing, discovering, enriching, and consuming data. Initially, civil servants identify and prepare relevant raw data in various non-proprietary formats using internal procedures. In the next step, selected datasets are published. A data catalogue improves the usability of the metadata by enabling consistent search and navigation across multiple data sources.
Using linked data and semantic web technologies allows for sophisticated structuring, filtering, or combining and mapping different vocabularies used in different city administration departments to derive aggregated datasets. Such linked data can be stored centrally within the ODP, which provides enrichment tools and triple store services. In the final step (in the Open Data lifecycle) data is consumed by citizens, businesses, and civil society via the use of web (or mobile device) applications. These applications serve multiple roles, including increasing transparency, participation, and collaboration. In addition, they also contribute new data, which can further be published, discovered, enriched, and consumed.
ODP Features Classified by User Roles
The ODP has varying capabilities for diverse stakeholders, including data users, data owners, data stewards, and platform administrators. Data users can search, browse, download, rate, comment, tweet, and discuss datasets. Additionally, they can query data (and metadata) via an API and get notifications for new datasets and categories. Via the ODP provided data portal, data owners can maintain data (and metadata) entries throughout the lifecycle (i.e., users can publish new datasets, including new bulk dataset uploads, edit datasets, or even hide their datasets). The data steward role refers to an individual (or group) that is tasked with transforming existing registered data in the ODP into linked data to provide seamless machine-readable access for web mashups and mobile applications. Uploading RDF (resource description framework) objects into the ODP data store is a core feature of the platform. Other main features are multi-language support, customizable data categories and metadata schema.
ODP: Technological Aspects
The Fraunhofer FOKUS developed ODP is an integrated solution based on open source software. The platform consists of three components:
- a data catalog based on the CKAN (comprehensive knowledge archive network) software,
- Liferay, which implements an Open Data portal, and
- a repository for linked data based on Virtuoso DBMS
Additionally CKAN provides numerous features including customizable metadata schemas, metadata-APIs, and dataset harvesting capabilities. However, the ODP goes beyond CKAN.
The ODP complements CKAN with a feature-rich, easily extendable Open Data portal, as a front-end component. Implemented in Liferay, a Java-based open source content-management-system, the Open Data portal integrates social media and supports community activity features, comprehensive user management, as well as a user friendly interface.
Unlike other platforms (e.g., Socrata), the ODP is free and it is available as open source software under the AGPL (Affero general public license) terms. To enable Open Cities app (i.e., application) challenges, the ODP was successfully deployed and hosted by Fraunhofer FOKUS for Amsterdam, Barcelona, and Berlin.

The bridge's rising costs of upkeep and maintenance, as well as local traffic delays due to frequent repairs, eventually led to the decision to replace the structure with a wider, reinforced concrete bridge 1500 feet upriver. The project also will incorporate new features into the structure, including bikeways and a fishing pier. Total construction is estimated at $230 million.
Construction on the new bridge began in mid-2007. Building the two bascule piers proved to be a major challenge on the project—the two matching bascule piers range from 50 to 75 feet tall at various points.
In addition to the overall size of the concrete placement, most of the construction had to be conducted in the water. Equipment had to be barged to the jobsite, causing numerous access issues.
Placing the concrete for the control house also was a challenge for the construction team. This part of the project includes an 8-foot-wide concrete deck extended from the vertical surface of the structure that is 50 feet in length.
The general contractor Cianbro/Middlesex opted for Doka forms to help meet the various project challenges.
Support frames were used to form the bascule wall's cantilevered concrete. Various spindles and channels helped to create different angles required on the project.
Kaven Philbrook, project manager for the bridge, chose Doka's A Frames to assist in the concrete placement. Mounted to the structure's surface using fabricated heads and anchors, these frames serve to support the cantilever.
More than 30,000 square feet of Framed Framax Xlife Formwork, 100 18-foot-long MF 240 climbing platforms, and several custom fabrications were used to form this large-area project.
Because of its easy use, the form-work system is flexible enough to meet the demanding forming needs of the project. The system can be quickly and safely stripped, enabling faster reset and setup for the next casting. Standard components also were used in unusual combinations, conforming to the bridge's unique design. This also allowed for adaptation as conditions changed from pour to pour.
Doka provided the equipment preassembled nearby and sent by barge directly to the jobsite. Cianbro/Middlesex was able to pick up the formwork and set it in place.
The bridge is expected to open in the autumn of 2012.

Dealing with a huge amount of data puts the requirement for efficient data access more critical in data grids. Improving data access time is a one way of reducing the job execution time i.e. improving performance. To speed up the data access and reduce bandwidth consumption, data grids replicate data in multiple locations. This paper studies a new data replication strategy in data grid, which takes into account two important issues concerning replication: storage capability of different nodes and bandwidth consumption between nodes. It also considers the popularity of the file for replacement. Lesser popular files get less priority then the higher popular file. The authors also need to consider the limitation on storage.

1,3-Benzenediol: Human health tier II assessment
21 April 2016
CAS Number: 108-46-3
- Chemical Identity
- Import, Manufacture and Use
- Existing Work Health and Safety Controls
- Health Hazard Information
- Risk Characterisation
- NICNAS Recommendation
This assessment was carried out by staff of the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) using the Inventory Multi-tiered Assessment and Prioritisation (IMAP) framework.
The IMAP framework addresses the human health and environmental impacts of previously unassessed industrial chemicals listed on the Australian Inventory of Chemical Substances (the Inventory).
The framework was developed with significant input from stakeholders and provides a more rapid, flexible and transparent approach for the assessment of chemicals listed on the Inventory.
Stage One of the implementation of this framework, which lasted four years from 1 July 2012, examined 3000 chemicals meeting characteristics identified by stakeholders as needing priority assessment. This included chemicals for which NICNAS already held exposure information, chemicals identified as a concern or for which regulatory action had been taken overseas, and chemicals detected in international studies analysing chemicals present in babies' umbilical cord blood.
Stage Two of IMAP began in July 2016. We are continuing to assess chemicals on the Inventory, including chemicals identified as a concern for which action has been taken overseas and chemicals that can be rapidly identified and assessed by using Stage One information. We are also continuing to publish information for chemicals on the Inventory that pose a low risk to human health or the environment or both. This work provides efficiencies and enables us to identify higher risk chemicals requiring assessment.
The IMAP framework is a science and risk-based model designed to align the assessment effort with the human health and environmental impacts of chemicals. It has three tiers of assessment, with the assessment effort increasing with each tier. The Tier I assessment is a high throughput approach using tabulated electronic data. The Tier II assessment is an evaluation of risk on a substance-by-substance or chemical category-by-category basis. Tier III assessments are conducted to address specific concerns that could not be resolved during the Tier II assessment.
These assessments are carried out by staff employed by the Australian Government Department of Health and the Australian Government Department of the Environment and Energy. The human health and environment risk assessments are conducted and published separately, using information available at the time, and may be undertaken at different tiers.This chemical or group of chemicals are being assessed at Tier II because the Tier I assessment indicated that it needed further investigation.

What is uLaw codec?
What is uLaw codec?
Associated requirements: G. 711.0, G. 711.1
Likewise concern is, what is Alaw codec?
Presenting G711 aLaw G. 711 is an ITU-T basic algorithm for audio companding that is utilized for digital interaction systems and supported by the majority of VoIP companies. G. 711 codec offers the very best voice quality for VoIP.
Next To above, what is the distinction in between g711 and g729? The various codecs use various levels of compression. G711 offers an uncompressed high quality voice, however utilizes a great deal of bandwidth. G729 is compressed so that it utilizes less bandwidth at the expense of some sound quality, though it is still more than sufficient for many calls.
Merely so, what is ULAW and Alaw?
A-law vs u-Law The very first distinction in between the 2 is the vibrant series of the ouput; U-law has a bigger vibrant variety than a-law Dynamic variety is essentially the ratio in between the quietest and loudest noise that can be represented in the signal.
What is the distinction in between g711a and g711u?
G711a is alaw and G711u is ulaw. Generally, the one you utilize depends where in the world you are. In Australia (and essentially the majority of the world outside the U.S.A.) we utilize alaw. So, a call made with G711a can be more quickly become a TDM voice call when it strikes the PSTN.
Associated Concern Responses.
What is a codec another name for?
Codec Codec is brief for "coder-decoder." It is an algorithm utilized to encode information, such as an audio or video.
What is g711 codec?
G. 711 is an ITU-T requirement (Suggestion) for audio companding, entitled Pulse code modulation (PCM) of voice frequencies, it is a necessary requirement in lots of innovations, such as in the H. 320 and H. 323 requirements. 711 is a narrowband audio codec that offers toll-quality audio at 64 kbit/s.

G. 723.1 (6.3 Kbps) 24 Bytes 30 ms
What is a law and mu law?
The μ- law algorithm (in some cases composed " mu law", typically estimated as " u law") is a companding algorithm, mainly utilized in 8-bit PCM digital telecommunication systems in The United States and Canada and Japan. It is among 2 variations of the G. Companding algorithms decrease the vibrant series of an audio signal.
Why is companding required?
The information rate is very important in telecommunication since it is straight proportional to the expense of transferring the signal. Conserving bits is the very same as conserving cash. Companding is a typical method for minimizing the information rate of audio signals by making the quantization levels unequal.
Why companding is utilized in PCM?
Companding is utilized in pulse code modulation ( PCM). The procedure includes reducing the variety of bits utilized to tape-record the greatest (loudest) signals. In the digital file format, companding enhances the signal-to-noise ratio at minimized bit rates.
What is a law in digital interaction?
An A- law algorithm is a basic companding algorithm, utilized in European 8-bit PCM digital interactions systems to enhance, i.e. customize, the vibrant series of an analog signal for digitizing. It is among 2 variations of the G.
What is companding in interaction?
Companding describes a method for compressing and after that broadening (or decompressing) an analog or digital signal. It is a mix of the words "compressing" and "broadening." This twin-sequential procedure is non-linear general however direct over brief time periods. Information is compressed prior to being sent.
What do you suggest by law?
Meaning of law is a guideline of conduct established by the federal government or society over a specific area. Law follows specific practices and custom-mades in order to handle criminal activity, company, social relationships, home, financing, and so on. The Law is managed and implemented by the managing authority.
The number of codecs exist?
Codecs are compression innovations and have 2 parts, an encoder to compress the files, and a decoder to decompress. There are codecs for information (PKZIP), still images (JPEG, GIF, PNG), audio (MP3, AAC) and video (Cinepak, MPEG-2, H. 264, VP8). There are 2 type of codecs; lossless, and lossy.

By using entire islands as experimental laboratories, two Dartmouth biologists have performed one of the largest manipulations of natural selection ever conducted in a wild animal population. Their results, published online on May 9 by the journal Nature, show that competition among lizards is more important than predation by birds and snakes when it comes to survival of the fittest lizard.
Podcast: Lizards and Evolution
"When Tennyson wrote that nature is'red in tooth and claw', I think the image in his head was something like a Discovery Channel version of a lion chasing down a gazelle" said Ryan Calsbeek, an assistant professor of biology at Dartmouth College and a co-author of the study. "While that may often be the case, intense natural selection can also arise through competition. Sometimes, death by competitor can be more important than death by predator".
To show this effect, the researchers covered multiple small islands in the Bahamas with bird-proof netting to keep predatory birds at bay. Other islands were left open to bird predators, and on still other islands, the researchers added predatory snakes to expose the lizards to both bird and snake predators. Next, they tracked the lizards over the summer to record which lizards lived and which died on the different islands.
"We found repeated evidence that death by predators occurred at random with respect to traits like body size and running ability" said Robert Cox, a post-doctoral researcher at Dartmouth and Calsbeek's co-author. "But we also found that increasing the density of lizards on an island consistently created strong natural selection favoring larger size and better running ability."
Calsbeek and Cox explain that in high-density populations, the intensity of competition for food, space, and other resources is likely to increase. In turn, this increased competition favors the biggest, toughest lizards on the island.
"The lizards play for keeps," said Calsbeek, "and there's no room for the meek when times get tough".
Though the researchers note that competition will not always be more important than predation in other species or in different environments, they emphasize that their study has broad social implications because it demonstrates the ability to conduct evolutionary experiments in natural animal populations.
"Many people are skeptical of evolutionary biology because they perceive it as a purely historical science that can't be tested experimentally. Here, we're providing a real experimental test of natural selection as it happens in the wild. That's an exciting way for us to advance the public's perception of evolution" said Calsbeek.

Virtual Shelter Tour
Shelters kill every day in the U.S. despite empty cages. Empty cages mean less cleaning, less work, less effort for shelter staff. Empty cages can be found in many shelters throughout the country. Here, a shelter keeps most of the cat cages empty during the height of the busy summer season despite falsely claiming it has no choice but to kill cats "for space."
Staff cut corners by cleaning dog kennels with high pressure hoses and caustic chemicals while leaving the dogs in the run, instead of removing them as they should. The dogs either become sick or become fearful of people and then are killed as "unadoptable." Here, dogs are wet and shivering after being sprayed with water and chemicals.
They call it "humane euthanasia" but shelter killing is often anything but humane. Even the methods used are troublesome. Some shelters place dogs and cats in gas chambers like the one here. Gas systems take time to kill–during which animals experience distress and anxiety, and can struggle to survive. They can result in animals surviving the gassing, only to suffer more. And they take longer to kill if animals are young, old, or have respiratory infections, which can be common in shelters. They are designed for the ease of shelter workers, not care and compassion for the animals and should never be used.
View a video of animals being gassed and then being thrown in a dumpster: Gas Chambers
(Caution: this film videotaped inside a U.S. animal shelter is very graphic)
The preferred method of killing in the U.S. is an overdose of barbiturates. Although better than gas systems by far, lethal injection is not always painless either, as anyone who has witnessed the killing of animals in shelters can attest. With some animals, there is fear, disorientation, nausea and many times even a struggle. A dog who is skittish, for example, is made even more fearful by the smells and surroundings of the animal shelter. He doesn't understand why he is there and away from the only family he has ever loved. To kill this dog, he may have to be "catch poled," a device that wraps a hard-wire noose around the dog's neck. He struggles to free himself from the grip, only to result in more fear and pain when he realizes he cannot. The dog often urinates and defecates on himself, unsure of what is occurring. Often the head is held hard to the ground or against the wall so that another staff member can enter the kennel and inject him with a sedative. While the catch-pole is left around the neck, the dog struggles to maintain his balance, he tries to stand, but his legs give way. He is frightened by the people around him. He does not understand what is happening. He goes limp and then unconscious. That is when staff administers the fatal dose.

We are a nation of cat lovers. The cat is the most popular pet in America, with about 90 million of them sharing our homes. The vast majority will be killed, many without ever being offered for adoption. Here, a filthy litter box–one hour after the cage was supposedly "cleaned."
Here, a cat declared "aggressive" and scheduled for destruction as "unadoptable" by untrained shelter staff.
The same cat cuddling up to someone.
From algae covered water bowls for dogs, to rabbits with no water, to puppies languishing with no care, too many U.S. animal shelters neglect, abuse and needlessly kill animals.
Whose fault is it anyway?
To this day, animal shelters continue to ignore their own culpability in the killing, while professing to lament it as entirely the fault of the public's failure to spay/neuter or to make lifetime commitments to their animals. Instead of embracing the No Kill philosophy, many shelters are still not sterilizing animals before adoption or providing the public with affordable alternatives. Some do not have foster care programs and do not socialize and/or rehabilitate dogs with behavior issues. Still others do not take animals offsite for adoption, have not developed partnerships with rescue groups, limit volunteerism, are not practicing trap-neuter-release for feral cats, and still retain adoption hours that make it difficult for working people or families to visit the shelter. The failure to implement these programs is mostly the result of one fact: they believe a certain level of killing is acceptable. Indeed, some would go as far as to deny they are even killing.
In March of 2006, at the largest national animal sheltering conference in the United States, a featured speaker and expert on "euthanasia" flatly denied that shelters were even killing animals: "We are not killing [animals in shelters]. We are taking their life, we are ending their life, we are giving them a good death… but we are not killing."
When you sugarcoat the words, you do not make the act more palatable.
The power to change the status quo is in your hands.

The nuclear reactor tragedy in the town of Chernobyl, north of Kiev, on April 26th 1986, led to much of Sweden being covered in a toxic cloud of radioactive iodine and cesium-137. When the rain came, the area around Gävle in the southern part of the Norrland region took the brunt of the radioactive pollution.
With only days to go to the 30th anniversary of the disaster, traces of increased radiation levels can still be found in Sweden's wild elk and reindeer, which are herded by the indigenous Sami community.
"The levels are low for slaughtered reindeer, but this doesn't happen automatically – the Sami people are working very hard on this," Pål Andersson, researcher at the Swedish Radiation Safety Authority (Strålsäkerhetsmyndigheten), told the TT newswire on Thursday.
In the past two years, only two out of around 50,000 reindeer in Sweden have been classed as unfit to consume due to high radiation levels. But the preventative work is likely to continue for many years to come.
"They will probably have to keep these special arrangements going for a long time, like special feeding of the reindeer, altered slaughter periods and actively moving reindeer from contaminated areas," said Andersson.
Meanwhile, cesium levels in elk, while low, are not decreasing as rapidly as they did in earlier years.
"It's gone very slowly lately. But it varies a lot between individual elks. If you as a consumer want to know how much cesium there is in an elk the specific elk has to be examined," said Andersson.
However, according to experts the risk for consumers of being exposed to harmful levels of radiation from eating elk, or picking mushrooms or berries in the Swedish forests, is low. Only one percent of radioactive substances most Swedes end up being exposed to in a year can be traced back to Chernobyl.
"If you pick berries and mushrooms and live in these fallout areas, there's still no risk," said Kettil Svensson, toxicologist at Sweden's Food Agency (Livsmedelsverket).


loading speed, not disk space, so be prepared for your app to grow dramatically if you include a lot of PVR images. To reduce the size of your PVR images on disk you can gzip them, which can reduce their size significantly, depending on the image content. To gzip a pvr image, you can use the following command line tool:
gzip {image_file}
To individually gzip a folder of PVR images, CD to the image folder, then you can use the following command:
find ./ -name \*.pvr | sed 's/\.pvr//g' | xargs -I % -n 1 gzip %.pvr
You can load the zipped images by including the GZIP library in your project (_URL_ The GLImage class will automatically detect the presence of the GZIP library and unzip the images when loading them.
The GLModel class also supports gzip, so if you have very large model files you may want to try gzipping them to reduce your app size.
Premultiplied Alpha
Images with an alpha channel can be generated with either straight or premultiplied alpha. Typically on iOS, images use premultiplied alpha because it is more efficient for rendering. PNG images added to your Xcode project will be automatically converted to use premultiplied alpha, so GLImage assumes premultiplied alpha when loading images.
When using PVR images, straight alpha can result in a one-pixel black or white halo around the opaque parts of the image when rendered (you can see slight white halos in the PVR images in the GLImage demo), so it's recommended that you use premultiplied alpha with PVR images, which can be achieved using the PVRTexTool by adding the -p flag (this is already included in the examples above).
At present, there's no way to automatically detect the type of alpha when loading a PVR image, so if you have generated your PVRs with straight alpha, GLImage will still assume they are premultiplied, which will make them look even worse when they are displayed. To correct this, call [image imageWithPremultipliedAlpha:NO] on the image after loading it to create a copy that will treat the image as having straight alpha instead.
The sprite sheet formats supported by GLImageMap include metadata indicating whether the texture file has premultiplied alpha or not, so no further work is needed when loading sprite sheets with GLImageMap.
Using Xcode 5 / SpriteKit texture atlases
The GLView library can load sprites stored in the Xcode 5 / SpriteKit texture atlas format. To use a texture atlas, first create a folder containing all of your sprite images (both standard and @2x variants) with the extension .atlas, and add it to your project.
Then, in your project build settings, search for "SpriteKit" and set the "Enable Texture Atlas Generation" option (this may appear as SPRITEKIT_TEXTURE_ATLAS_OUTPUT if you have not yet imported the atlas), with the default "Output Texture Atlas Format" of "RGBA8888_PNG" (GLView does not currently support any of Xcode's compressed texture formats).
There is no need to import the SpriteKit framework. When importing your sprite sheet using the GLImageMap +imageMapWithContentsOfFile method, either specify the file extension "atlasc" (note the "c"), or leave off the path extension and GLImageMap will automatically find the atlas file if available.
You will need to use Xcode 5 or above to generate the atlas files, but they can be loaded and used by GLImageMap for apps running on iOS 4.3 and above - they are not limited to iOS 7.

GSSI looks at using Ground Penetrating Radar for Cemetery Mapping
Across the United States, a large amount of forgotten burials of unmarked and lost graves exist.
Geophysical techniques, including ground penetrating radar (GPR), are needed to non-destructively locate these burials in cemeteries and other locations. Cemetery mapping using GPR is gaining in popularity. Two-dimensional (2D) real-time evaluation of GPR profiles is quick and efficient, and especially useful for projects with time constraints or abundant obstacles in the survey area.
GSSI looks at using Ground Penetrating Radar for Cemetery Mapping
Lost graves stem from cemetery age and population growth
Historical cemeteries can go back hundreds of years. Over time, missing, fallen, or poorly placed headstones can complicate the assumed physical location of grave sites. The original documentation may be unavailable or unreadable, further leading to confusion. GPR service providers are increasingly being used to generate up-to-date burial maps or clear areas for new burials.
In addition, modern population growth has led to increased infrastructure and city sprawl. There are documented cases where contractors were given permission to build over forgotten burial grounds. In some cases a GPR investigation may be conducted to determine the existence of a cemetery, presence, or absence of burials, whether the graves have been disturbed, and factors related to relocation recommendations. In other cases, GPR may be used to evaluate graves overlooked during cemetery relocated due to urban expansion.

Three keys to successfully using GPR equipment
Those looking to use GPR equipment for cemetery mapping surveys should follow these best practices:
1. Know your GPR equipment and learn how best to use it in cemeteries
The first key to success is to determine the right type of equipment to use and get to know the equipment. Find white papers or posters that describe GPR methods for cemeteries and become familiar with how burials appear in GPR datasets.
In addition, consider specialized training from archaeologists or others on using GPR equipment for cemetery mapping. For example, GSSI offers GSSI Academy classes on cemetery mapping and equipment use.
2. Conduct pre-survey research
The best experience is hands-on practice. Consider reaching out to a local cemetery and ask permission to scan their grounds prior to conducting cemetery surveys as a service offering. Ask to be present when someone is digging a new grave. Research the age of the cemetery and how it may have been managed over time and then look at the existing marked graves in the cemetery to determine the direction and orientation of the graves. Ideally, the GPR should pass over burials perpendicular to their long axis (90 degrees).
Before beginning any cemetery mapping project, become familiar with local soil conditions, including soil composition and depth to bedrock/ledge. If you cannot see a representative soil profile, check out the USDA NCRS soil map and other online soil science resources.
3. Consider the variables
The quality of a GPR survey is greatly affected by soil conditions, weather, and the surrounding environment. Note these observances in your field notes and determine if other geophysical techniques can be used to compliment the GPR survey. Be especially cautious if the ground is saturated with water. If shoes squish when one walks over the site, consider returning once the water content has decreased. Look for large trees in the vicinity, signs of large rocks and animal burrows; these and other targets could generate false positive indicators of burials.
2D cemetery mapping using GPR
Two-dimensional (2D) real-time evaluation of GPR profiles is quick and efficient, and a common method for projects with time constraints or where there are abundant obstacles in the survey area.
The basic technique calls for collecting GPR profiles perpendicular to assumed burial orientation and identifying potential burial-related targets and associated soil disturbances. Not all burials (especially older ones) will exhibit a hyperbolic target due to decay of wood coffins, but there should be evidence of the grave shaft as a result of excavation and filling of the grave.
Water content is the single most important factor affecting GPR performance. Water slows down the GPR velocity, increases dielectric, and can mix with soil chemistry to increase conductivity levels. In high-dielectric conditions, hyperbolic targets are narrow and more difficult to see, reducing the chance of observing a burial target. Certain soil textures, like clay and silt, hold more water and may have inherently higher conductivity. High soil conductivity is like a lightning rod for GPR energy, whereby the GPR signal is dissipated into the ground and does not return to the antenna when reflected by a target or layer. This vastly reduces depth penetration, and in extreme cases may limit data collection to one or two feet below the surface.
Another soil-related factor is the presence of gravel, larger rocks, or boulders. Gravel can create clutter in the GPR profile, while cobbles and boulders create confusing hyperbolic targets. The disturbance in the ground from an animal burrow can also generate hyperbolas that would confuse a user when trying to locate burials.
The key to differentiating actual burials from false positives is to look beyond the targets and to evaluate the entire GPR profile. Rocks, roots, and animal burrows may appear as hyperbolic targets, but they usually will not have a soil disturbance above them. Burial targets must have an associated soil disturbance, and this might appear as broken soil layers or an anomalous area above the target. Roots and animal burials may extend across the project area for tens of feet, but a human burial will not. Marking potential targets with paint or pin flags will help visualize the length of targets and assist in ruling some of them out.
The choice of GPR antenna is of critical importance to the success of 2D cemetery mapping. Higher frequency antennas, like 900 MHz and 2700 MHz, may exhibit impressive resolution but cannot penetrate down to typical burial depths. Alternatively, lower frequencies greatly improve the depth of investigation, but they sacrifice resolution in the process. Since burials can be somewhat deeply buried, and they may not present large targets in profiles. People who are conducting a cemetery survey should use a 400 MHz or 350MHz HyperStacking® antenna to achieve the best results. These antennas provide the ideal interplay between depth and resolution and will provide adequate depth penetration without generating unwanted soil clutter in your data.
Another important factor is burial container material. Some wooden coffins may persist for a long time, but in most cases they will quickly collapse and erode away. In these cases, cemetery mappers will not be looking for the target, but rather the hole, or soil disturbance, that the target is/was in. Brick and concrete vaults last much longer and should be easier to locate. However, these containers are larger than wooden coffins and the top of the container may only be 1-2 feet below the surface; they can be easily missed if the survey is focused on depths of 4-6 feet. Lastly, one might encounter cemeteries where burials were previously exhumed. In this scenario the remains and container are removed, and all that is left is a filled-in excavation that is often larger than the original grave shaft.
Peter Leach conducts a 2D data collection in a cemetery in Massachusetts with the UtilityScan Pro with the 350 HS antenna.
Advantages and disadvantages of 2D data collecting
The advantages of 2D data collecting in a cemetery include speed of data collection, on the spot marking, and ease of data interpretation.
Speed of data collection
Since collection of 2D data does not require setting up a grid most of the time prepping the area is cut down or gone. Due to the speed of data collection while collecting a 2D file, one can easily prep out the area with a few passes around the location to scout for the best place to collect the survey.
On the spot marking
Spray paint and flags can be used to simply mark the possible grave location on the spot in the cemetery. When marking the possible target on the ground, also mark the spot in the notebook, along with notations of obstructions and possible graves. Make sure to take photographs of the landscape at the same time.
Data interpretation
It is easy to view 2D data on the screen and analyse the results on the spot. Unlike 3D data, 2D data collection does not require post processing to view the data.
Disadvantages of 2D data collection for cemetery mapping include interference that inhibits real-time interpretation, difficulty in differentiating targets, and the danger of incomplete coverage.
GPR data from cemeteries can inherit external noise, soil-related issues, and other unavoidable data problems that inhibit real-time interpretation. Continuous EM noise will generate horizontal noise bands that span soil disturbances and give the impression that soil layers are continuous, and proximity to the transmission source will compound this issue. Sporadic EM noise can generate a snowy or static overprint and obscure real data. Soil conditions create their own noise signatures, and usually these are exacerbated by certain clay varieties and overall water content. Salt, nitrates, calcium carbonate, and other chemical components will increase conductivity and reduce penetration depth while vastly reducing interpretive potential.
Use a notebook to mark possible targets, obstructions, and possible graves
Differentiating targets
The equifinality of GPR reflections is also of concern, as targets and layers from completely different origins can be indistinguishable on GPR

Icelandic Is Essential to Getting Access to Society
"Having good command of Icelandic is the key to access to society and a prerequisite for people's wishes and dreams coming true," Helgi Gíslason, principal of Fellaskóli grade school in Breiðholt, Reykjavík, tells Morgunblaðið. "Good progress in school brings confidence, and that's how opportunities present themselves," he adds. "The basis for that is good command of Icelandic, which we put every effort into improving, along with the whole school community in the neighborhood."
Fellaskóli stands out among other Icelandic schools, due to its high ratio of students whose native language is not Icelandic. About 80 percent of the students, or 330 of them, are bilingual, meaning that either one or both parents are of foreign origin. Many immigrant families live in the multi-cultural Fellahverfi neighborhood.
A new initiative, called Draumaskólinn, meaning 'Dream School' has just been launched in the Fellahverfi neighborhood. It involves a three-year plan – a cooperative effort between students and staff of Fellaskóli grade school, with the participation of the Ministry of Education and the City of Reykjavík. It includes cooperation with the neighborhood preschools and recreational center as well.
The goal is to increase the ability of students whose native language is not Icelandic to read and speak Icelandic and to increase their vocabulary, thereby helping them develop a positive self-concept.
"The role of grade schools is manifold," Helgi states, "including educating students and encouraging their active participation in a diverse democratic society. This includes offering equal opportunity and facilities. Having obtained the same foundation and education, graduating students ought to have equal opportunities once they move on to further studies and work."

After 6 months - fix available for Microsoft DNS cache poisoning
On April this year I discovered a new vulnerability that enables
DNS cache poisoning attack against the Windows DNS server. Today
now publicly available, I can finally share my research finding
with you.
type of attack but a different vulnerability and a different DNS
server. It's interesting that both BIND and Microsoft had
different, and at the same time fundamentally flawed
implementations of DNS (with Microsoft's implementation being
more easily predictable than those of BIND).
Using this attack an attacker can remotely poison the cache of
who use this DNS server to reach fraudulent websites each time
they try to access real websites.
Windows DNS Server (part of Windows 2003 Server and Windows 2000
The concept of DNS cache poisoning was discussed many times
before. However, this attack was considered impractical for the
leading industrial DNS servers due to the transaction ID
mechanism that DNS servers implement today. The transaction ID is
supposed to be a secure, random number that the attacker must
transaction ID values which make enumeration impractical in the
current network conditions.
The weakness I found is in the transaction ID generation
algorithm of Windows DNS Server. By observing a few consecutive
transaction IDs from the same DNS server an attacker can predict
its next value.
This weakness can be turned into a mass attack in the following
starts a chain reaction that eventually poisons the DNS server's
cache (subject to some standard conditions) and associates
that use this DNS server will now reach the fraudulent website
each time they try to reach the real website.
The algorithm for predicting the transaction ID is very simple.

Microsoft were informed on April 30th, and patched versions of
Windows DNS Server are now available on their website (see

Researchers from NASA's Goddard Space Flight Center (GSFC) and several other government and academic institutions have created four new supercomputer simulations that for the first time combine their mathematical computer models of the atmosphere, ocean, land surface and sea ice. These simulations are the first field tests of the new Earth System Modeling Framework (ESMF), an innovative software system that promises to improve and accelerate U.S. predictive capability ranging from short-term weather forecasts to century-long climate change projections.

These images depict wind and temperature data. This field test is a collaboration among NASA's Goddard Space Flight Center (GSFC), the National Center for Atmospheric Research (NCAR), and the National Centers for Environmental Prediction (NCEP). Credit: Carlos Cruz, Shujia Zhou, Northrop Grumman IT/GSFC; Arlindo da Silva, GSFC; Erik Kluzek, NCAR; Weiyu Yang, NCEP.
Although still under development, many organizations and research institutions are starting to adopt ESMF. Under a partnership, groups from NASA, the National Science Foundation (NSF), the National Oceanic and Atmospheric Administration (NOAA), the Department of Energy (DOE), the Department of Defense and research universities are using ESMF as the standard for coupling their weather and climate models to achieve a realistic representation of the Earth as a system of interacting parts, unifying much of the modeling community. ESMF makes it easier to share and compare alternative scientific approaches from multiple sources, uses remote sensing data more efficiently and eliminates the need for individual agencies to develop their own coupling software.
"The development of large Earth system applications often spans initiatives, institutions and agencies, and involves the geoscience, physics, mathematics and computer science communities. With ESMF, these diverse groups can leverage common software to simplify model development," said NASA ESMF principal investigator Arlindo da Silva, a scientist in GSFC's Global Modeling and Assimilation Office.
NASA's Earth-Sun System Technology Office/Computational Technologies Project funds the field tests and overall ESMF development. The partners on the field tests are DOE's Los Alamos National Laboratory (LANL), the Massachusetts Institute of Technology (MIT), NASA's Jet Propulsion Laboratory, NOAA's Geophysical Fluid Dynamics Laboratory (GFDL) and National Centers for Environmental Prediction (NCEP), NSF's National Center for Atmospheric Research (NCAR) and the University of California, Los Angeles (UCLA).
The newly completed field tests, known as interoperability experiments, show that this new approach in coupling models can be successful. For instance, temperature and wind outputs are similar around the globe when ingesting data into an NSF-NASA atmosphere model as they are for the atmosphere model used operationally by NOAA. Although most of the experiments would require exhaustive tuning and validation to be scientifically sound, they already show that ESMF can be used to assemble coupled applications quickly, easily and with technical accuracy.
"These interoperability experiments illustrate the role ESMF can play in integrating the national Earth science resources," da Silva said. "Using existing data assimilation technology from NCEP, the finite-volume Community Atmosphere Model, or fvCAM, was able to ingest conventional and satellite observations, a capability that could open the door to using the fvCAM for weather as well as climate prediction." The fvCAM, which includes land surface capabilities, was developed by NCAR, with key components from GSFC.
The second experiment combines NCEP's data assimilation technology with the Aries atmosphere model originally developed by the NASA Seasonal-to-Interannual Prediction Project. Aries is typically coupled with an ocean model to run experimental forecasts of phenomena such as El Niño and its effects on precipitation. Among additional advantages, the two field tests enable the intercomparison of systems for satellite data assimilation.
The coupled experiments have many other potential applications. The third experiment, combining a GFDL atmosphere-land-ice model with an MIT ocean-sea ice model (known as MITgcm), may ultimately bring new insights into ocean uptake of carbon dioxide and other important atmospheric gases and how this process affects the climate.
In an early independent adoption of ESMF technology, UCLA researchers have successfully coupled their Atmospheric General Circulation Model to the MITgcm for the first time and updated a previous coupling to the LANL Parallel Ocean Program model. They made experimental predictions of the El Niño/Southern Oscillations with the coupled models using initial states provided by JPL's Estimating the Circulation and Climate of the Ocean (ECCO) project. These preliminary results validate ESMF performance in terms of scientific fidelity and support the importance of ECCO products for improving short-term climate forecasts.
Demonstrations of the software and the field tests are taking place at the 4th ESMF Community Meeting at MIT in Cambridge, Mass., July 20–22. Reaching beyond the ESMF partnership, the research team releases the software to the scientific community via the Internet. NCAR, home of the core implementation team, is scheduled to release ESMF Version 2.2.0 this month.

Physical Security
Physical security protects the people and properties of an organization, but also information. Besides technical security, information also needs physical security. The most important threats against which physical security protects an organization, are intentional threats from people. Examples are theft and accidental access. In this training you will learn which measures an organization can take to ensure physical security and what your role is in this.
Learning Objectives:
After the training you will be able to answer the following questions:
 - What is physical security?
 - Why is physical security important?
 - How do you contribute to physical security yourself?


The influence of hemp extract in combination with ginger on the metabolic activity of metastatic cells and microorganisms.
Molecules. 2020 Oct 28 ;25(21). Epub 2020 Oct 28. PMID: 33126621
Abstract Title:
The Influence of Hemp Extract in Combination with Ginger on the Metabolic Activity of Metastatic Cells and Microorganisms.
This study presents an investigation of the anticancer and antimicrobial ability of a combination of ginger and cannabis extracts in different ratios (1:1, 7:3 and 3:7). Extracts were obtained using various methods (Soxhlet extractions, cold macerations, ultrasonic extractions and supercritical fluid extractions). The antioxidant activity and the presence of total phenols were measured in the extracts, and the effect of the application extracts in various concentrations (c = 50, 20, 10, 5, 1, 0.1, 0.01 mg/mL) on cells was investigated. Higher values of antioxidants were measured at the ratio where ginger was predominant, which is reflected in a higher concentration of total phenols. Depending on the polyphenol content, the extracts were most effective when prepared supercritically and ultrasonically. However, with respect to cell response, the ratio was shown to have no effect on inhibiting cancer cell division. The minimum concentration required to inhibit cancer cell growth was found to be 1 mg/mL. High-performance liquid chromatography (HPLC) analysis also confirmed the effectiveness of ultrasonic and supercritical fluid extraction, as their extracts reached higher cannabinoid contents. In both extractions, the cannabidiol (CBD) content was above 30% and the cannabidiolic acid (CBDA) content was above 45%. In the case of ultrasonic extraction, a higher quantity of cannabigerol (CBG) (5.75± 0.18) was detected, and in the case of supercritical fluid extraction, higher cannabichromene (CBC) (5.48 ± 0.13) content was detected, when compared to other extraction methods. The antimicrobial potential of extracts prepared with ultrasonic and supercritical extractions on three microorganisms (,and) was checked. Ginger and cannabis extract show better growth inhibition of microorganisms in cannabis-dominated ratios for gram-positive bacterium, MIC = 9.38 mg/mL, for gram-negative bacterium, MIC>37.5 mg/mL and for thefungus MIC = 4.69 mg/mL. This suggests guidelines for further work: a 1: 1 ratio of ginger and hemp will be chosen in a combination with supercritical and ultrasonic extraction.

First, ok-to-good question. Definitely not a bad question. To answer it, you just have to know what a shader is and why you need one.
A shader is exactly what it sounds like - it "shades" vertices and pixels different colors. "Shading" isn't just "making it darker" (as the technical artistic term means I believe), it's application of textures, lighting, and everything else that gives a vertex it's final color.
"Shading" often makes the most sense if you think about some light source. You can't really have toon shading without a light source. You have to have light (and an angle to the light) to know how to shade an object in that light. And that's the job of the shader.
So, now you have a vertex/pixel shader that will do toon shading in Blender. Great. Why do you need to know HLSL if you can make a toon shader in Blender?
If Blender exports HLSL code that you can plug into XNA, then you don't need to write the HLSL yourself. You are correct. You wouldn't need to hear about, see, or touch HLSL code if Blender exports it for you. But I'm not sure if Blender can do that.
So if Blender does not HLSL shading code, then you need to write a toon shader in HLSL because all you'd get is the model and vertices and their respective solid colors, but you wouldn't get "how it should look at every single angle and under every possible light source" right - that needs to be computed at runtime (by a shader).


Racially Segregated Proms Still a Tradition?
promI was shocked reading this article in the New York Times, which reports that racially segregated proms are still a tradition in some rural towns in the South.
For example, students of Montgomery County High School in Georgia attend either (what they refer to as) "the black-folks prom" or "the white-folks prom."
How is this permitted?
Because the proms are private—sponsored and organized NOT by the schools but outside of school by student committees with the help of parents—segregation is allowed. Even though interracial friendships and relationships are common at the school, according to the article:
The article reports that students find segregated proms to be "awkward" and even hurtful. Still, when asked why this situation continues year after year, both students and parents fall back on the same reasoning: It's tradition.
Is this prejudice masquerading as tradition? What do you think?

Mark a Member as a Duplicate
While Membership automatically identifies possible duplicate members based on matching the first name, surname and date of birth of two records, it is possible for some duplicates to'slip through the cracks'. For example, this could occur if any of the three 'duplicate identification fields' (first name, surname, DOB) are not exactly the same, e.g. an incorrect date of birth, or variation or error in the spelling of a name. In such cases, the member can be manually flagged as a duplicate, which can then be resolved by the association.
Both associations and clubs are able to mark a member as a possible duplicate. Firstly, ensure that both records do belong to the same person, then complete the following:
2. Locate the new member (not the original) record. You may find the search box or 'Advanced Search' options useful for quickly locating a member record.
3. Click on the View Record button next to the name of the member you want to mark as a duplicate.
4. The member's record will open. Click on Mark Member as Duplicate on the right hand side.
5. A message will appear, reminding you to only mark the new record (not the original) as a duplicate. Click on Mark as Duplicate.
6. A message will appear confirming that the member has been marked as a duplicate. The member has now been added to the list of possible duplicates to be resolved by the association. If you are logged into Membership at the association level, you can click on Resolve Duplicates to go directly to the Duplicate Resolution screen.

Cereals 2018: NFU launches 'Your Harvest' arable campaign
PUBLISHED: 19:20 14 June 2018 | UPDATED: 19:20 14 June 2018
The National Farmers' Union (NFU) has launched a new campaign aiming to celebrate the contribution the arable sector makes to the nation's economy, food supply and environment.
The launch of "Your Harvest" at the Cereals 2018 show in Cambridgeshire included the release of a guide for farmers, outlining the importance of the sector, with suggestions of how to share that story with parliamentarians throughout Harvest 2018 and beyond.
NFU crops board chairman Tom Bradshaw, who farms near Colchester, championed the initiative. He said: "The UK arable sector has a brilliant story to tell. And never has there been a more important time to tell it.
"There's no question that the arable sector will face its fair share of change as the UK leaves the EU, particularly around farming's relationship with the natural environment. This campaign presents an opportunity for farmers to be on the front foot; to proactively talk about the millions of tonnes of grain we produce, how we produce it and what that contributes to the UK. It's never been more important to talk about the role that farmers play in managing the great British countryside that is taken for granted.
"As part of the #YourHarvest campaign I'm urging every arable farmer to spare two hours of their harvest to host a farm visit with an MP, to use the facts and statistics in the guide and champion the industry that I know we're all proud to work in."
NFU president Minette Batters said: "The importance of the arable sector is absolutely huge, and it is really important that we have a positive story to underpin it.
"We have had politicians talking about drowning our soils in pesticides and declaring chemical warfare on our soils. We need to remind ourselves of the journey we have been on in the last 20 years. We have come such a long way. We have halved our use of pesticides and fertiliser, and the world's eyes are on our market place."

Let $M$ be a closed smooth manifold. A generic diffeomorphism $\phi: M\rightarrow M$ has non-degenerate fixed points, i.e. the intersections of its graph with the diagonal in $M\times M$ are all transverse. In a generic one-parameter family $(\phi_t)$ of diffeomorphisms (say starting at the identity) we cannot request that the fixed points of $\phi_t$ be non-degenerate for all $t$. Nonetheless we can arrange that degenerate fixed points occur only for finitely many values of $t$ and that they be of "birth-death" type. In particular, the fixed point set of each $\phi_t$ is still isolated.
How "non-generic" is it for a diffeomorphism to have a fixed point set that "carries topology", i.e. not only its fixed point set $F$ is infinite but it has non-trivial homology and the map $H_\ast(F)\rightarrow H_\ast(M)$ is non-trivial at some positive degree? The reasoning above shows that the codimension of these diffeomorphisms in $Diff(M)$ is at least 2. Is it finite/very high/infinte?
As a particular example, let $M=\mathbb{CP}^n$ and consider the set $\mathcal {E}$ of diffeomorphisms whose fixed point set contains a line, i.e. the restriction of a generator $u\in H^2(\mathbb{CP}^n;\mathbb Q)$ to its fixed point set is non-zero. Does $\mathcal{E}$ have codimension greater than $2$ in $Diff(M)$? Analogous questions can be asked in the volume-preserving or symplectic cases.

William Hall was born on April 28, 1827 in Nova Scotia. He was the son of free slaves.
He volunteered for the Royal Navy sometime before 1852 and was decorated in the Crimean War in 1854-55. In 1857, he was sent with a brigade of sailors to Lucknow, India to relieve the British garrison besieged there. Only Hall and one officer survived and between them, they loaded and served the last gun. For this, he won the Victoria Cross, making him the first coloured man to do so.
Hall rose to the position of Quartermaster and Petty Officer before retiring in 1876. He died at home in Avonport, Nova Scotia on August 25, 1904.


- To train an inference network jointly with a deep generative topic model, making it both scalable to big corpora and fast in out-of-sample prediction, we develop Weibull hybrid autoencoding inference (WHAI) for deep latent Dirichlet allocation, which infers posterior samples via a hybrid of stochastic-gradient MCMC and autoencoding variational Bayes. The generative network of WHAI has a hierarchy of gamma distributions, while the inference network of WHAI is a Weibull upward-downward variational autoencoder, which integrates a deterministic-upward deep neural network, and a stochastic-downward deep generative model based on a hierarchy of Weibull distributions. The Weibull distribution can be used to well approximate a gamma distribution with an analytic Kullback-Leibler divergence, and has a simple reparameterization via the uniform noise, which help efficiently compute the gradients of the evidence lower bound with respect to the parameters of the inference network. The effectiveness and efficiency of WHAI are illustrated with experiments on big corpora.

- DALI – Digital Addressable Lighting Interface, is a trademark of DiiA (DALI Alliance), a IEEE (Industry Standards and Technology Organization, Inc) for network-based systems that control lighting in building automation.
- DALI is specified by technical standards IEC 62386 and IEC 60929.
- A DALI network consists of a controller, a power supply and one or more slave devices.
- Each device is assigned a unique short address in the numeric range 0 to 63.
- DALI gateways can be used to implement systems that have upto 64 devices.
Data is transferred between controller and devices over a two-wire bus, with a fixed data transfer rate of 1200 bit/s.
- The bus is used for both signal and power. A power supply provides ≤ 250 mA at 16 V DC; each device may draw up to 2 mA.
DALI 2 Introduction
- DALI-2 is the updated and improved version of the DALI lighting protocol, which includes more features and more product types and has a strong focus on product interoperability.
- Specifically, DALI-2 refers to version 2 of IEC 62386, the international DALI standard. DALI-2 extends and enhances the strengths of DALI as a dedicated, standardised protocol for digital lighting control.
- DALI-2 brings standardisation to system components such as sensors and other input devices, as well as application controllers, which are the 'brains' of a DALI system.
- Which are intended to ensure that products from different suppliers are able to work together.
- Compared with the original DALI version 1 standard, DALI-2 includes clearer specifications for control gear features such as timing, fading, power-on and start-up, as well as new features such as extended fade times.
- DALI-2 is designed for backwards compatibility, so DALI-2 control gear can be used in older systems.
- DALI-2 certification brings the promise of significantly improved multi-vendor interoperability compared with the current DALI (version-1) systems in the market.
- Testing procedures for DALI-2 are much more detailed and comprehensive than for DALI version-1, and will be further improved if new issues are identified.
- DALI-2 includes control devices for the first time
- Control devices were not included in version 1 of the DALI standard, meaning it is not possible for control devices to carry the DALI version-1 logo. Only certified products can carry the DALI-2 logo.
- Benefits of DALI-2 for control devices:
- Application controllers and Input devices defined
- Single-masters and multi-masters allowed
- Event priorities defined
- Separate addressing & grouping from control gear.

Deploying a Kotlin App to Heroku
Since its earliest release, Java has touted itself as a "write once, run everywhere" programming language. The idea was that a programmer could develop an app in Java, have it compiled down to bytecode, and become an executable that can run on any platform, regardless of operating system or platform. It was able to do so in part by a runtime known as the Java Virtual Machine, or JVM.
To Java's credit, the JVM was (and still is!) an incredibly fine-tuned runtime that abstracted away a computer's underlying hardware. While Java as a programming language survives to this day, it is often viewed as cumbersome, stodgy, and representative of an outdated approach to implementing solutions.
In the last 10 years, more and more languages that run on the JVM have developed, but look and feel nothing like Java. One such language is Kotlin. Because of the JVM, it has no real performance advantages over regular Java. Still, its strength lies in the fact that it prioritizes legibility in a way that Java does not. Consider, for example, printing a substring in Java:
// Java
String input = "What is the answer to the Ultimate Question of Life, the Universe, and Everything? 42";
String answer = input.substring(input.indexOf("?") + 1);
System.out.println(answer);
Enter fullscreen mode Exit fullscreen mode
You must first get the index of the character you want to be in the substring, add one (since strings are zero-indexed), and call System.out.println to write to stdout.
In Kotlin, this is much shorter:
// Kotlin
val input = "What is the answer to the Ultimate Question of Life, the Universe, and Everything? 42"
val answer = input.substringAfter("?")
println(answer)
Enter fullscreen mode Exit fullscreen mode
Kotlin has garnered so much interest that Google even recommends it over Java for developing Android apps.
In this post, we'll take a quick look at how to develop an app in Kotlin. We'll build a simple API with a PostgreSQL database and deploy it to Heroku to see it live.
Prerequisites
Before we begin, you'll need to make sure you've got the following software installed on your machine:
 1. An account on Heroku. This is completely free and doesn't require any payment information.
 2. The Heroku CLI. Once your application is on Heroku, this will make managing it much easier.
 3. You'll need to have Kotlin installed (>= 1.4).
 4. You'll also need Gradle installed (>= 7.0).
You will also need to be a little familiar with Git and have it installed on your machine.
We're going to be using the IntelliJ IDE for this Kotlin app. Their documentation provides some guidance on how to create a new project. Make sure you select the following options:
 - We want to create a Kotlin application that uses Gradle as a build system
 - Set the name of the project to kotlin-api
 - Set the JDK version to 16. If you don't have this version installed, you can select Download JDK… from the dropdown, then choose Oracle Open JDK version 16
After the IDE sets everything up, you should have a directory structure that looks roughly like this:
kotlin-api
├── build.gradle.kts
└── src
 ├── main
 │ ├── kotlin
Enter fullscreen mode Exit fullscreen mode
Our Kotlin files will be kept in src/main/kotlin, and our build logic will be in build.gradle.kts.
Getting started
Gradle is a build tool for a variety of languages. It also acts as a dependency management tool, similar to Maven. You'll already have some lines in your build.gradle.kts file, which the IDE automatically added to be helpful. You can delete all of that, and paste in these lines instead:
plugins {
 id("java")
 id("org.jetbrains.kotlin.jvm") version "1.5.10"
 id("org.springframework.boot") version "2.4.3"
 id("io.spring.dependency-management") version "1.0.11.RELEASE"
}
group "com.example"
version "0.0.1"
repositories {
 mavenCentral()
}
dependencies {
 implementation("org.jetbrains.kotlin:kotlin-stdlib")
 implementation("org.springframework.boot:spring-boot-starter-web")
 implementation("org.springframework.boot:spring-boot-starter")
 developmentOnly("org.springframework.boot:spring-boot-devtools")
}
Enter fullscreen mode Exit fullscreen mode
These lines specify our project's dependencies and where to find them. For example, we want to use [org.springframework.boot](_URL_ at version 2.4.3, which is why it's defined within the plugins block. We point out the repositories where the packages can be found—at mavenCentral()—and which exposed classes we want to use (implementation( "org.springframework.boot:spring-boot-starter-web")).
Let's create two small files to test our setup. Create a file called Application.kt in the src/main/kotlin folder and paste in the following:
package com.example
import org.springframework.boot.SpringApplication
import org.springframework.boot.autoconfigure.SpringBootApplication
@SpringBootApplication
open class Application
fun main(args: Array<String>) {
 SpringApplication.run(Application::class.java, *args)
}
Enter fullscreen mode Exit fullscreen mode
This starts a default app using the Spring framework. The real magic happens in this next file, Controller.kt, which you should create alongside Application.kt in src/main/kotlin:
package com.example
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.PathVariable
import org.springframework.web.bind.annotation.RestController
@RestController
class GreetingController {
 @GetMapping("/{name}")
 fun get(@PathVariable name: String) = "Hello, $name"
}
Enter fullscreen mode Exit fullscreen mode
Here, we define a route (@GetMapping("/{name}")), where {name} is a dynamic value. By placing this decorator over a Kotlin method (fun get, or "a function named get"), we're able to match the route to whatever behavior we want—in this case, returning a greeting with the path name for a GET request.
In order for the IDE to know how to launch our application, we need to create a run configuration. At the top of the IDE menu, click the button that says Add Configuration…. Select Add new run configuration, then choose Gradle from the list. For the Gradle project name, enter kotlin-api. In the Tasks field, type bootRun. bootRun is a Gradle task provided by the Spring framework which will compile our code and start the server. Click Ok; you should now have a green Play button in your IDE menu bar. When you click on this, the IDE will execute gradle bootRun to build this Kotlin app and start the server. When that finishes, navigate to http://localhost:8080/world. You should see a nice greeting.
Interacting with the database
Now, let's get to the (somewhat) serious stuff. Suppose we wanted to attach a database to this project. In a Maven/Java world, we'd need to update an XML file and add a reference to a JAR file. In Gradle, we can get by with just adding a few lines to our build.gradle.kts file:
dependencies {
 # ...
 implementation("com.zaxxer:HikariCP:4.0.3")
 runtimeOnly("org.postgresql:postgresql")
 # ...
}
Enter fullscreen mode Exit fullscreen mode
Here, we've included HikariCP in our project, which is a popular database connection driver. We also indicate that we want to "load" the org.postgresql library during runtime. With just these two lines, we've let our configuration know that we want to interact with a PostgreSQL database. If you already have a PostgreSQL database running locally, that's great. You'll be able to continue the rest of this guide


When we send an email in Microsoft outlook there is a possibility mail send to wrong person or content of the mail is not correct. We don't have to worry about this there is a option in outlook to recall the message send by us.
1. Go to sent items
2. Open the message which we wanted to recall by double clicking the message
3. Click Actions Icon
 As soon as clicked actions button we can see many options. If we want to recall the message completely click "Recall This Message" option. In case we wanted to replace with correct message use the option "Resend This Message". This recalling mechanism works if the receiver is not read his email.

One of the configuration variables we can find in the solrconfig.xml file is maxBooleanClauses, which specifies the maximum number of boolean clauses that can be combined in a single query. The question is, do I have to worry about it when using filters in Solr? Let's try to answer that question without getting into Lucene and Solr source code.
Let's assume that we have the following query we want to change:
q=category:1 AND category:2 AND category:3... AND category:2000
Sending such a query to the Solr instance with the default configuration would result in the following exception: "too many boolean clauses". Of course we could modify the maxBooleanClauses variable in solrconfig.xml file and get rid of the exception, but let's try do it the other way:
Let's change the query to use filters
So, we change the above query to use filters – the fq parameter:
q=*:*&fq=category:(1 2 3... 2000)
We send the query to Solr and … and again the same situation happens – exception with the "too many boolean clauses" message. It happens because Solr has to "calculate" filter content and thus run the appropriate query. So, let's modify the query once again:
Final query change
After the final modification our query should look like this:
After sending such a query we will get the search results (of course if there are documents matching the query in the index). This time Solr didn't have to run a single, large boolean query and that's why we didn't exceed the maxBooleanClauses limit.
To sum up
As you can see the answer to the question asked in the begining of the post depend on the query we want to run. If our query is using AND boolean operator we can use fq parameter because multiple fq parameters are concatenated using AND. However if we have to use OR we would have to change the limit defined by maxBooleanClauses configuration variable. But please remember that changing this limit can have a negative effect on performance and memory usage.

Learning Discriminative Stein Kernel for SPD Matrices and Its Applications
Stein kernel (SK) has recently shown promising performance on classifying images represented by symmetric positive definite (SPD) matrices. It evaluates the similarity between two SPD matrices through their eigenvalues. In this paper, we argue that directly using the original eigenvalues may be problematic because: 1) eigenvalue estimation becomes biased when the number of samples is inadequate, which may lead to unreliable kernel evaluation, and 2) more importantly, eigenvalues reflect only the property of an individual SPD matrix. They are not necessarily optimal for computing SK when the goal is to discriminate different classes of SPD matrices. To address the two issues, we propose a discriminative SK (DSK), in which an extra parameter vector is defined to adjust the eigenvalues of input SPD matrices. The optimal parameter values are sought by optimizing a proxy of classification performance. To show the generality of the proposed method, three kernel learning criteria that are commonly used in the literature are employed as a proxy. A comprehensive experimental study is conducted on a variety of image classification tasks to compare the proposed DSK with the original SK and other methods for evaluating the similarity between SPD matrices. The results demonstrate that the DSK can attain greater discrimination and better align with classification tasks by altering the eigenvalues. This makes it produce higher classification performance than the original SK and other commonly used methods.
