Question of the Week: AR/AI
Is robo-journalism valuable?
This week's Question: Lars Eidnes, a Norwegian developer, recently created software that uses Recurrent Neural Networks (RNN)—a form of “deep learning”—to write new "clickbait” headlines. After training the software with several million articles from BuzzFeed, Gawker, Jezebel, the Huffington Post, and...

Question of the Week: AR/AI
If artificial intelligence outsmarts two live contestants, is that a bad sign for the humans?
This week's question addresses a robot and one of America's most well-known game shows. A supercomputer named Watson, designed by IBM and consisting of 90 IBM Power 750 Express servers, is set to face two human contestants on the US quiz show Jeopardy this...

Virtual Patient
Researchers from Rensselaer Polytechnic Institute are using a $2 million grant from the National Institutes of Health (NIH) to develop a physics-based virtual model that can simulate a patientís breathing in real time. When used in conjunction with existing 3D models, adding the fourth dimension of time could improve the accuracy...

PHANTOM PAIN TREATMENT
Researchers at the University of Manchester (Manchester, UK) have devised an experimental method of virtual reality for the treatment of phantom limb pain (PLP) experienced by some amputees. Using headsets, data gloves, and other sensors, amputees used their remaining physical limbs to control the movements of a...

Program for Simulating Dynamics of Multibody Systems
The Dynamics Algorithms for Real-Time Simulation (DARTS) computer program solves the equations of motion of tree-topology, flexible, and/or multibody mechanical systems as diverse as molecules, mechanisms, robots, spacecraft, and ground vehicles. It has proven to be particularly useful for...
