Is glass a true solid? Researchers have combined computer simulation and information theory, originally invented for telephone communication and cryptography, to answer this puzzling question. This puzzle of a material which seems solid to any observer while appearing fluid under the microscope is an old one. And, even with the help of today's supercomputers, it seems impossible to verify in simulations whether a glass ever stops flowing.
Software that Knows the Risks: Planning Algorithms Evaluate Probability of Success, Suggest Low-risk AlternativesJanuary 16, 2015 1:57 pm | by Larry Hardesty, MIT | News | Comments
Imagine that you could tell your phone that you want to drive from your house in Boston to a hotel in upstate New York, that you want to stop for lunch at an Applebee’s around 12:30, and that you don’t want the trip to take more than four hours. Then imagine that your phone tells you that you have only a 66 percent chance of meeting those criteria — but that if you can wait until 1:00 for lunch, or if you’re willing to eat at TGI Friday...
For household robots to be practical, they need to be able to recognize the objects they’re supposed to manipulate. While object recognition is one of the most widely studied topics in AI, even the best detectors still fail much of the time. Researchers believe the robots should take advantage of their mobility, imaging objects from multiple perspectives. Matching up objects in the different images, however, poses computational challenges.
Wave equations help describe waves of light, sound and water as they occur in physics. Also known as partial differential equations, they have valuable potential for predicting weather or earthquakes, or certain types of natural disasters. Tao is interested in the theoretical side of these equations, seeking to discover with computer algorithms whether they can behave in a way that typically is the opposite of what occurs in the real world.
Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing phases, generally accessible at very low temperature, exhibit unique conductivity properties, which are particularly robust against external perturbations, suggesting promising technological applications.
Researchers have found that, based on enough Facebook Likes, computers can judge your personality traits better than your friends, family and even your partner. Using a new algorithm, researchers have calculated the average number of Likes artificial intelligence (AI) needs to draw personality inferences about you as accurately as your partner or parents.
This is not a text for the novice. However, for those math/statistics aficionados, there is much to be had. The book’s great strength lies in two areas: the first is Peter Congdon’s generation of an excellent bibliography of the most modern techniques available, and the other is his (slightly) more straightforward explanations of the strengths and weaknesses of these techniques and suggestions for optimizing the results.
The human lament that things in the past were much simpler is an accurate observation made from the perspective of riding along an exponentially increasing complexity curve. Examining the present or looking into the future can be a confusing torrent of concepts, vocabulary and technologies that appear to be spiraling out-of-control. At the First IEEE Integrated STEM Education Conference, Professor Steve Zilora reflected on this increase...
A computer program that taught itself to play poker has created nearly the best possible strategy for one version of the game, showing the value of techniques that may prove useful to help decision-making in medicine and other areas. The program considered 24 trillion simulated poker hands per second for two months, probably playing more poker than all humanity has ever experienced.
A new technique to help surgeons find the exact location of heart defects could save lives, help them to treat patients more effectively and save health service cash. The development will allow non-invasive detection of the origin of heart problems and allow more effective treatment.
Research conducted at Griffith University may lead to greatly improved security of information transfer over the Internet. Physicists from the Centre for Quantum Dynamics demonstrate the potential for "quantum steering" to be used to enhance data security over long distances, discourage hackers and eavesdroppers and resolve issues of trust with communication devices.
Nearly 75,000 high-school students on approximately 3,000 teams at 107 venues around the globe joined the kickoff event on January 3, 2015, of the 2015 FIRST Robotics Competition (FRC) via live Comcast NBCUniversal broadcast. FIRST is a not-for-profit organization devoted to helping young people discover and develop a passion for science, engineering, technology and math.
In 2005, a semi-truck hauling 35,000 pounds of explosives through the Spanish Fork Canyon in Utah crashed and caught fire, causing a dramatic explosion that left a 30-by-70-foot crater in the highway. Fortunately, there were no fatalities. Such accidents are extremely rare but can, obviously, have devastating results. So, understanding better exactly how such explosions occur can be an important step to learning how better to prevent them.
In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now, an MIT spinout is bringing similar drive-by innovations to energy efficiency by deploying cars with thermal-imaging rooftop rigs that create heat maps of thousands of homes and buildings per hour, detecting fixable leaks in building envelopes — windows, doors, walls and foundations — to help curb energy loss.
With drug-resistant bacteria on the rise, even common infections that were easily controlled for decades — such as pneumonia — are proving trickier to treat with standard antibiotics. New drugs are desperately needed, but so are ways to maximize the effective lifespan of these drugs. Researchers used software they developed to predict a constantly-evolving infectious bacterium's countermoves to one of these new drugs ahead of time...
A previously unknown mathematical property has been found to be behind one of nature’s greatest mysteries — how ecosystems survive. Found in nature and common to all ecosystems, Trophic Coherence is a measure of how plant and animal life interact within the food web of each ecosystem — providing scientists with the first-ever mathematical understanding of their architecture and how food webs are able to grow larger and more stable
With a new look at daily data from the NOAA/NASA Suomi National Polar-orbiting Partnership satellite, a NASA scientist and colleagues have identified how patterns in nighttime light intensity change during major holiday seasons — Christmas and New Year's in the United States and the holy month of Ramadan in the Middle East.
Turbulent combustion simulations, which provide input to the design of more fuel-efficient combustion systems, have gotten their own efficiency boost. Researchers developed new algorithmic features that streamline turbulent flame simulations, which play an important role in designing more efficient combustion systems. They tested the enhanced code on the Hopper supercomputer and achieved a dramatic decrease in simulation times.
Monstrous moonshine, a quirky pattern of the monster group in theoretical math, has a shadow — umbral moonshine. Mathematicians have proved this insight, known as the Umbral Moonshine Conjecture, offering a formula with potential applications for everything from number theory to geometry to quantum physics.
Just in time for Christmas, Richard Zhang reveals how to print a 3-D Christmas tree efficiently and with zero material waste, using the world’s first algorithm for automatically decomposing a 3-D object into what are called pyramidal parts. The algorithm promises to become a big deal in the world of 3-D printing, and also has applications for designing molds and for casting.
Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA).
About 95 percent of the more than 10,000 bird species known only evolved upon the extinction of dinosaurs about 66 million years ago. According to computer analyses of the genetic data, today's diversity developed from a few species at a virtually explosive rate after 15 million years. Scientists designed the algorithms for the comprehensive analysis of the evolution of birds; a computing capacity of 300 processor-years was required.
Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...
Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver — say, a computer and a printer — are off by even a single bit relative to each other, communication between them breaks down entirely.
World's Oldest Computer, Ancient Greek Antikythera Mechanism, 100 Years Older than Previously BelievedDecember 9, 2014 2:10 pm | by University of Puget Sound | News | Comments
An ancient Greek astronomical puzzle has one more piece in place. The new evidence results from research by James Evans, professor of physics at University of Puget Sound, and Christián Carman, history of science professor at University of Quilmes, Argentina. The two researchers published a paper advancing our understanding of the Antikythera Mechanism, an ancient Greek mechanism that modeled the known universe of 2,000 years ago.
