Researchers discover quantum algorithm that could improve stealth fighter design
(Phys.org) —Researchers at the Johns Hopkins University Applied Physics Laboratory (APL) have devised a quantum algorithm for solving big linear systems of equations. Furthermore, they say the algorithm could be used to ...
Network paradox may help algorithms overcome 'universal limitation'
Researchers prove quantum algorithm works by solving linear equations on a quantum computer
Leaner Fourier transforms: Algorithm separates signals into their individual frequencies using minimal number of samples
The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing. The algorithm allowed computers to quickly perform Fourier transforms—fundamental ...
Evolution inspires more efficient solar cell design: Geometric pattern maximizes time light is trapped in solar cell
(Phys.org)—The sun's energy is virtually limitless, but harnessing its electricity with today's single-crystal silicon solar cells is extremely expensive—10 times pricier than coal, according to some ...
Four microphones, computer algorithm enough to produce 3-D model of simple, convex room
Blind people sometimes develop the amazing ability to perceive the contours of the room they're in based only on auditory information. Bats and dolphins use the same echolocation technique for navigating ...
Quantum cryptography put to work for electric grid security
A Los Alamos National Laboratory quantum cryptography (QC) team has successfully completed the first-ever demonstration of securing control data for electric grids using quantum cryptography.
Researchers discover the 'anternet'
(Phys.org)—On the surface, ants and the Internet don't seem to have much in common. But two Stanford researchers have discovered that a species of harvester ants determine how many foragers to send out ...
High-frequency trading tactic lowers investor profits
High-frequency trading strategies that exploit today's fragmented equity markets reduce investor profits overall, according to new findings by University of Michigan engineering researchers. The study is believed to be the ...
Carnegie Mellon tracking algorithm inspired by Harry Potter's Marauder's map (w/ video)
Multiview 3-D photography made simple
Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can.
Doing the math 'predicts' which movies will be box office hits
(Phys.org) —Researchers have devised a mathematical model which can be used to predict whether films will become blockbusters or flops at the box office – up to a month before the movie is released.
New algorithm for message dissemination in decentralized networks faster than its predecessors and guarantees delivery
Ad hoc networks—communication networks set up on the fly by mobile sensors—pose problems that ordinary office networks don't. Ad hoc networks are usually decentralized, meaning that no one node knows ...
New algorithm can dramatically streamline solutions to the 'max flow' problem
Finding the most efficient way to transport items across a network like the U.S. highway system or the Internet is a problem that has taxed mathematicians and computer scientists for decades.
