Novel Method Enables Infinite Walking in VR

12 months ago Association for Computing Machinery 0
In the ever-evolving landscape of virtual reality (VR) technology, a number of key hurdles remain. But a team of computer scientists have tackled one of the major challenges in VR that will greatly improve user experience–enabling an immersive virtual experience while being physically limited to one’s actual, real-world space. The research team will present their Read More

Looking Ahead: What’s Next for IoT

1 year ago Ahmed Banafa, San Jose State University 0
Over the past several years, the number of devices connected via Internet of Things (IoT) has grown exponentially, and it is expected that number will only continue to grow. By 2020, 50 billion connected devices are predicted to exist, thanks to the many new smart devices that have become standard tools for people and businesses Read More

A soft solution to the hard problem of energy storage

1 year ago Drexel University 0
It’s great in the lab, but will it actually work? That’s the million-dollar question perpetually leveled at engineering researchers. For a family of layered nanomaterials, developed and studied at Drexel University—and heralded as the future of energy storage—that answer is now, yes. For some time, researchers have been working on using two-dimensional materials, atomically thin nanomaterials, Read More

Magnonic interferometer paves way toward energy-efficient information processing devices

1 year ago Lisa Zyga | PHYS.org 0
Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. Although magnon signals have discrete phases that normally cannot be changed continuously, the magnonic interferometer can generate a continuous change of the magnon signal. In the future, this ability could be used to design magnonic integrated Read More

Self-assembling 3-D battery would charge in seconds

1 year ago Cornell University 0
The world is a big place, but it’s gotten smaller with the advent of technologies that put people from across the globe in the palm of one’s hand. And as the world has shrunk, it has also demanded that things happen ever faster—including the time it takes to charge an electronic device. A cross-campus collaboration Read More

An electronic rescue dog

Trained rescue dogs are still the best disaster workers — their sensitive noses help them to track down people buried by earthquakes or avalanches. Like all living creatures, however, dogs need to take breaks every now and again. They are also often not immediately available in disaster areas, and dog teams have to travel from Read More

A New Method for Studying Semiconductor Nanoparticles Has Been Tested

1 year ago Siberian Federal University 0
A team from Siberian Federal University and Kirensky Institute of Physics (Siberian Department of the Russian Academy of Sciences) applied a new method to study nanoparticles made of cadmium telluride (CdTe). They used a peculiar feature of this compound: its interaction with light differs depending on the magnetic field. The results of the study were Read More

Engineers on a roll toward smaller, more efficient radio frequency transformers

1 year ago University of Illinois at Urbana-Champaign 0
The future of electronic devices lies partly within the “internet of things—the network of devices, vehicles and appliances embedded within electronics to enable connectivity and data exchange. University of Illinois engineers are helping realize this future by minimizing the size of one notoriously large element of integrated circuits used for wireless communication—the transformer.  Three-dimensional rolled-up Read More

Heat and Sound Wave Interactions in Solids could Run Engines, Refrigerators

1 year ago Purdue University 0
A solid can serve as a medium for heat and sound wave interactions just like a fluid does for thermoacoustic engines and refrigerators – resulting in leak-free machines that can stay operating longer. Leaky systems have limited how engineers design thermoacoustic devices that rely on the interplay between temperature oscillations and sound waves. Researchers at Read More

Researchers hide information in plain text

1 year ago Columbia University School of Engineering and Applied Science 0
Computer scientists at Columbia Engineering have invented FontCode, a new way to embed hidden information in ordinary text by imperceptibly changing, or perturbing, the shapes of fonts in text. FontCode creates font perturbations, using them to encode a message that can later be decoded to recover the message. The method works with most fonts and, Read More
