NASA and NOAA have provided nighttime and daytime views of the Blizzard of 2015. A combination of the day-night band and high-resolution infrared imagery showed the historic blizzard near peak intensity as it moves over the New York through Boston Metropolitan areas at 1:45 a.m. EST on January 27, 2015. Nighttime lights of the region were blurred by high cloud tops associated with the most intense parts of the storm.
Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first comprehensive map of layers deep inside the Greenland Ice Sheet, opening a window on past climate conditions and the ice sheet’s potentially perilous future. This allows scientists to determine the age of large swaths of the second largest mass of ice on Earth.
Scientists have taken a new path in the research into causes of epilepsy: They determined the networks of the active genes and — like a dragnet — looked for the "main perpetrators" using a computer model. In doing so, they discovered the molecule sestrin-3 as a central switch. In animal models, the scientists were able to demonstrate that inhibition of sestrin-3 leads to a reduction in seizures.
A new virtual reality system allows architects to view 3-D models of buildings in their intended shape, precisely where the buildings will be constructed. This provides a much clearer, realistic impression of the design. Digitization is fundamentally changing the work processes in architectural design, planning and construction work. Increasingly, CAD drawings are transferred to a central 3-D Building Information Model...
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.
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.
Visual-Environment 10.0 is a comprehensive simulation platform designed to enable the swift integration of calculations using the open source CFD modules of OpenFOAM. It allows engineers to accelerate preparation of most common CFD calculations, including airflow for external aerodynamics, internal airflow for underhood and climate control, and investigation of flow around rotating bodies.
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.
Environmental Intelligence: Significant Investment in Next-Gen Supercomputers to Improve Weather ForecastsJanuary 6, 2015 12:26 pm | by NOAA | News | Comments
NOAA has announced the next phase in the agency’s efforts to increase supercomputing capacity to provide more timely, accurate, reliable and detailed forecasts. By October 2015, the capacity of each of NOAA’s two operational supercomputers will jump to 2.5 petaflops, for a total of 5 petaflops — a nearly tenfold increase from the current capacity.
Unlike in mathematics, it is rare to have exact solutions to physics problems. The first exact solution that describes a system expanding at relativistic velocities radially and longitudinally has been presented by researchers. It applies to a wide array of physics contexts and will help to better model galactic structure, supernova explosions and high-energy particle collisions, such as those studied at the Large Hadron Collider at CERN.
A new mapping tool makes preparing for natural disasters and responding to their aftermath easier than ever. Researchers from the A*STAR Institute of High Performance Computing in Singapore have developed a computer model that analyzes networks of interconnected roads to predict the speediest routes for rescuers to take using real-time data uploaded by aid workers on the ground.
For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects. Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. However, a new study from MIT neuroscientists has found that one of the latest generation of these so-called “deep neural networks” matches the primate brain.
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.
Not long ago, it would have taken several years to run a high-resolution simulation on a global climate model. But using supercomputing resources at NERSC, climate scientist Michael Wehner was able to complete a run in just three months. What he found was that not only were the simulations much closer to actual observations, but the high-resolution models were far better at reproducing intense storms, such as hurricanes and cyclones.
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.
