Researchers are working on tech so machines can thermally ‘breathe’ — ScienceDaily

In the era of electric cars, machine learning and ultra-efficient vehicles for space travel, computers and hardware are operating faster and more efficiently. But this increase in power comes with a trade-off: They get superhot.

To counter this, University of Central Florida researchers are developing a way for large machines to “breathe” in and out cooling blasts of water to keep their systems from overheating.

The findings are detailed in a recent study in the journal Physical Review Fluids.

The process is much like how humans and some animals breath in air to cool their bodies down, except in this case, the machines would be breathing in cool blasts of water, says Khan Rabbi, a doctoral candidate in UCF’s Department of Mechanical and Aerospace Engineering and lead author of the study.

“Our technique used a pulsed water-jet to cool a hot titanium surface,” Rabbi says. “The more water we

Caterpillar bets on self-driving machines impervious to pandemics

CHICAGO (Reuters) – Question: How can a company like Caterpillar CAT.N try to counter a slump in sales of bulldozers and trucks during a pandemic that has made every human a potential disease vector?

Answer: Cut out human operators, perhaps?

Caterpillar’s autonomous driving technology, which can be bolted on to existing machines, is helping the U.S. heavy equipment maker mitigate the heavy impact of the coronavirus crisis on sales of its traditional workhorses.

With both small and large customers looking to protect their operations from future disruptions, demand has surged for machines that don’t require human operators on board.

Sales of Caterpillar’s autonomous technology for mining operations have been growing

Based on optical matter, new machines could be used to move and manipulate tiny particles — ScienceDaily

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics and particle sorting.

“Our work addresses a long-standing goal in the nanoscience community to create self-assembling nanoscale machines that can perform work in conventional environments such as room temperature liquids,” said research team leader Norbert F. Scherer from the University of Chicago.

Scherer and colleagues describe the new nanomachines in Optica, The Optical Society’s (OSA) journal for high-impact research. The machines are based on a type of matter known as optical matter in which metal nanoparticles are held together by light rather than the chemical bonds that hold together the atoms that make up typical matter.

“Both the energy for assembling the machine and the power to make it work come from light,” said Scherer. “Once

Fast-forwarding quantum calculations skips past the time limits imposed by decoherence, which plagues today’s machines — ScienceDaily

A new algorithm that fast forwards simulations could bring greater use ability to current and near-term quantum computers, opening the way for applications to run past strict time limits that hamper many quantum calculations.

“Quantum computers have a limited time to perform calculations before their useful quantum nature, which we call coherence, breaks down,” said Andrew Sornborger of the Computer, Computational, and Statistical Sciences division at Los Alamos National Laboratory, and senior author on a paper announcing the research. “With a new algorithm we have developed and tested, we will be able to fast forward quantum simulations to solve problems that were previously out of reach.”

Computers built of quantum components, known as qubits, can potentially solve extremely difficult problems that exceed the capabilities of even the most powerful modern supercomputers. Applications include faster analysis of large data sets, drug development, and unraveling the mysteries of superconductivity, to name a
