Modern passenger airplanes already consume less than three liters fuel per one hundred kilometers and passenger. Scientists are currently working on further improving this value. In addition, engineers plan to optimize the combustion process such that exhaust gas emission is reduced considerably. For this purpose, they use supercomputers and simulation methods that are usually applied for tsunami calculations or for water effects in computer games.
Renderings of 3-D cells in the body are traditionally displayed using 2-D media, such as on a computer screen or paper; however, the advent of Virtual Reality (VR) headsets means it is now possible to visualize and interact with scientific data in a 3-D virtual world.
Researchers have shown how to write any magnetic pattern desired onto nanowires, which could help computers mimic how the brain processes information.
A team of leading computer scientists has developed a novel computational system to aid the design and fabrication of wind-up toys, focusing on automating the intricate interior machinery responsible for the toys' wind-up motion.
Researchers have developed a computer program to find new indications for old drugs. The computer program, called DrugPredict, matches existing data about FDA-approved drugs to diseases, and predicts potential drug efficacy. In a recent study, the researchers successfully translated DrugPredict results into the laboratory, and showed common pain medications -- like aspirin -- can kill patient-derived epithelial ovarian cancer cells.
Can a close look at the universe give us solutions to problems too difficult for a computer -- even if we built a computer larger than a planet? Physicist Stephen Jordan reflects on this question in a new NIST video, along with a scientific paper that considers one particular tough problem the universe might answer.
A link between young people's ability to perform well at two popular video games and high levels of intelligence has been uncovered.
Scientists have created and analyzed detailed photomosaics of the coral reef at Palmyra Atoll using advanced imaging and digitization technology.
A faster collision detection algorithm could enable robots to work more fluidly in the operating room or at home for assisted living. The algorithm, dubbed 'Fastron,' runs up to eight times faster than existing collision detection algorithms. It uses machine learning to help robots avoid moving objects and weave through complex, rapidly changing environments in real time.
Qubits, the key building blocks at the heart of every quantum computer, are extremely sensitive to interference and need to be shielded from unwanted signals, for example by using so-called nonreciprocal devices. But until now these devices were huge and produced unwanted magnetic fields themselves. Now, scientists have developed a new nonreciprocal device that is only a tenth of a millimeter wide, and -- maybe even more importantly -- is not magnetic.
Scrapbooks or social networks are collections of mostly unsorted data. The search for single elements in very large data volumes, i.e. for the needle in the data haystack, is extremely complex for classical computers. Scientists have now quantum mechanically implemented and successfully executed Grover's algorithm, a process for the quick finding of a search element in unsorted databases.
Researchers are developing a first-of-its-kind bioengineered robotic hand that will actually feel and adapt to its environment. This “living” robot will have its own peripheral nervous system directly linking robotic sensors and actuators.
Technology is paving the way for artificial intelligence (AI) to break free of the internet and cloud computing.
Researchers used Stampede2 to complete a 100-epoch ImageNet deep neural network training in 11 minutes -- the fastest time recorded to date. Using 1600 Skylake processors they also bested Facebook's prior results by finishing a 90-epoch ImageNet training with ResNet-50 in 32 minutes. Given TACC's large user base and huge capacity, this capability will have a major impact across all fields of science.
Artificial intelligence tool quantifies power imbalance between female and male characters in Hollywood movies
Researchers who used machine learning tools to analyze language in 800 Hollywood movie scripts found subtle but widespread gender bias in the amount of power and agency given to male and female characters.
A quest to help the systems software community work on very large supercomputers without having to actually test on them has spawned an affordable, scalable system using thousands of inexpensive Raspberry Pi nodes.
The way fruit flies identify similarities between odors offers a new approach for search algorithms.
Physicists have made a breakthrough in revising methods largely discarded 15 years ago. They have discovered a microscopic mechanism that will allow gallium nitride semiconductors to be used in electronic devices that distribute large amounts of electric power.
The first large-scale study of a low-tech, high-harm form of online harassment known as doxing, which involves collecting and publishing sensitive personal information to exact revenge, seek justice, or intimidate victims, revealed the primary motivations are revenge and justice. Researchers created a custom text classifier to sort through 1.7 million files. They found new abuse filters on Facebook and Instagram appear to be effective in making victims feel safer.
Cosmos code testbed helps develop new techniques for computational astrophysics. CosmosDG utilizes discontinuous Gelarkin methods, which improved accuracy over previous versions by several orders of magnitude.
