An intelligent system that predicts when alarms might be triggered could greatly improve the management of industrial plants.
An investigation into switching characteristics provides new criteria for achieving faster switching of magnetic memories.
'Trending' topics on Twitter show the quantity of tweets associated with a specific event but trends only show the highest volume keywords and hashtags, and may not give information about the tweets themselves. Now, using data associated with the Super Bowl and World Series, researchers have developed and validated a software program that analyzes event-based tweets and measures the context of tweets rather than just the quantity.
Consumers are increasingly turning to forums, video-sharing sites, and peer support groups to gather anecdotal health-care information and advice, which may distract them from more reliable and trustworthy sources. New research studies the characteristics of consumers who use the Internet to collect health-care information.
The pathogens posing the greatest risk to Europe based upon a proxy for impact have been identified by researchers using a 'big data' approach to scientific research. The top risk for both humans and animals was E.coli and in humans this was followed by two forms of HIV, Hepatitis C and Staphylococcus aureus, a bacteria which causes food poisoning and is increasingly resistant to antibiotics.
Engineers and physicians have developed a smartphone application that checks for jaundice in newborns and can deliver results to parents and pediatricians within minutes. Skin that turns yellow can be a sure sign that a newborn is jaundiced and isn't adequately eliminating the chemical bilirubin. But that discoloration is sometimes hard to see, and severe jaundice left untreated can harm a baby.
Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile?
It’s not the person posting 10,000 pictures a week of their cat who’s the big-time Facebook user. Instead, it’s the quiet ones who are logging in longer, says research.
A statistical model allows researchers to remove false positive findings that plague modern research when many dozens of factors and their interactions are suggested to play a role in causing complex diseases.
A new study of financial innovations before and during the last financial crisis indicates that financial innovations are not all bad. Many provide positive returns.
Algorithms to identify weak spots in tendons, muscles and bones prone to tearing or breaking have been developed by researchers. The technology, which needs to be refined before it is used in patients, one day may help pinpoint minor strains and tiny injuries in the body’s tissues long before bigger problems occur.
By combining plasmonics and optical microresonators, researchers have created a new optical amplifier (or laser) design, paving the way for power-on-a-chip applications.
For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by new calculations. The effect could be used to build logical switches which are much faster than today's microelectronics.
Lowering internal eye pressure is currently the only way to treat glaucoma. A tiny eye implant recently developed could pair with a smartphone to improve the way doctors measure and lower a patient's eye pressure. Daily or hourly measurements of eye pressure could help doctors tailor more effective treatment plans.
Five years ago this month, one of the first U.S. outbreaks of the H1N1 virus swept through the Washington State University campus, striking some 2,000 people. A university math and biology professor has used a trove of data gathered at the time to gain insight into how only a few infected people could launch the virus's rapid spread across the university community.
A balance board accessory for a popular video game console can help people with multiple sclerosis (MS) reduce their risk of accidental falls, according to new research. Magnetic resonance imaging scans showed that use of the Nintendo Wii Balance Board system appears to induce favorable changes in brain connections associated with balance and movement.
A soccer game adapted for people with cerebral palsy has been designed that is operated with a foot switch, a push rod head switch and a hand switch. A new tool allows any player to have equal access with different physical conditions.
Scientists have developed smart bracelets - the Smart VIB (Very Important Bracelet) that enables clients access hotel rooms without the need for a card, make payments using the PayPal system, share experiences on social networks via the numerous tactile screen, and receive completely personalized services, while at all times guaranteeing protection of information.
The future of movie, sports and concert broadcasting lies in 4K definition, which will bring cinema quality TV viewing into people’s homes. 4K Ultra HD has four times as many pixels as today’s Full HD. And thanks to the new HEVC video compression standard, broadcasters can now transmit live video in the 4K digital cinema standard.
Researchers are investigating game-based verification that may improve computer security and reduce user frustration compared to typical “type-what-you-see” CAPTCHA tools that use static images.
