Qian also has developed an artificial intelligence-guided computer-vision system to monitor rail crossings and train platforms to spot people with potentially suicidal intentions-information that can be forwarded to either hotlines or local police. In the state capital of Columbia, 911 dispatchers now can use the system to save time on emergency calls by picking the best routes. His solution is a computer-vision system that monitors road traffic conditions and combines those data with schedules from rail operators to better estimate crossing times and when delays might occur. After seeing an ambulance blocked by a train, Yu Qian, an assistant professor of civil and environmental engineering at the University of South Carolina, was inspired to hunt for a way around the problem. They also can be deadly for people with medical emergencies if the ambulance or other first-responder vehicle gets held up. Traffic delays at rail crossings can be annoying. Meanwhile, the National Institute of Standards and Technology recently selected four new encryption algorithms that will become part of the “post-quantum” cryptographic standards expected to be finalized within the next two years. The technology not only holds promise for keeping data safe but also for storing vast amounts in small spaces rather than huge, power-hungry data centers. Using a liquid chromatography mass spectrometer to extract and analyze the polymer, the recipient was able to reveal the encryption key and decipher the book on the first try. The Texas team then mixed it into ink and wrote and mailed a letter to a colleague in Massachusetts. To test their method, the researchers used the polymer to encrypt a copy of the 1900 children’s classic The Wonderful Wizard of Oz. Each monomer corresponds to one of 16 symbols, enabling the team to encode the 256 bits of information so they could be read in correct order. This sequence-defined polymer is composed of a long chain of monomers concocted from commercially available amino acids. Their invention uses a plastic-like material synthesized by a robot as the storage medium. Researchers at the University of Massachusetts and University of Texas at Austin may have just the safeguard: a 256-bit encryption key that could thwart even the fastest computers. By some estimates, these superfast processors could hit the mainstream as soon as 2030, ushering in opportunities, particularly in areas like drug discovery, but also potential cybersecurity nightmares for banking and other industries whose standard data protections risk being cracked. Their work on entangled states, where two particles behave as one even when separated, paved the way for quantum computers. Clauser, 79 France’s Alain Aspect, 75 and Austrian Anton Zeilinger, 77. In October, the Nobel Prize in Physics was awarded to three pioneers of quantum information science-American John F. And while materials are cheap, manufacturing costs for synchronous reluctance motors are high because they’re extremely complex machines. A Tesla Model S motor, for example, whizzes at 18,000 rpm. Sansone, who’s now working on a sturdier, faster version of his invention, knows many challenges lie ahead. The method he used to produce the magnetic field remains a trade secret, but his prototype earned Sansone the $75,000 first prize at this year’s Regeneron International Science and Engineering Fair, the world’s largest and most prestigious high school STEM competition. Early tests for torque and efficiency showed that his model was 37 percent more efficient than a standard synchronous reluctance motor at 750 rpm. After 15 attempts, Sansone came up with a working prototype built from 3D-printed plastic, wires, and a steel rotor that doesn’t have air gaps. Synchronous reluctance motors, which aren’t powerful enough to use in vehicles, don’t use magnets because their steel rotors are pitted with air gaps that align with a rotating electromagentic field produced by coils of copper wire. EV motor magnets are part of a system that uses electromagenetic fields to spin a rotor. Sansone, who has some 60 inventions to his credit, including a go-kart that can exceed speeds of 70 mph, designed an alternative power pack based on a synchronous reluctance motor. Robert Sansone, a 17-year-old high school student and aspiring engineer from Fort Pierce, Florida, figured out a potential solution, reports Smithsonian magazine. Breakthroughs and trends in the world of technologyĮco-friendly electric vehicles (EVs) have a green-energy problem: their magnet-propelled motors need rare-earth elements that are not only expensive but also environmentally damaging to extract.
