Teaching a Computer to Play ‘Concentration’ Advances Security, Understanding of the Human Mind

Computer science researchers have programmed a computer to play the game Concentration (also known as Memory). The work could help improve computer security – and improve our understanding of how the human mind works.

The researchers developed a program to get the software system called ACT-R, a computer simulation that attempts to replicate human thought processes, to play Concentration. In the game, multiple matching pairs of cards are placed face down in a random order, and players are asked to flip over two cards, one at a time, to find the matching pairs. If a player flips over two cards that do not match, the cards are placed back face down. The player succeeds by remembering where the matching cards are located. (more…)

Optimizing Eyesight: R&D Collaboration Focuses on New System for Measuring and Improving Human Vision

With research and development assistance from the Georgia Tech Research Institute (GTRI) and seed funding from the Georgia Research Alliance (GRA), an Atlanta-based company is developing what it hopes will be the next-generation instrument for optimizing eyesight for the hundreds of millions of people who wear glasses or contacts – or who are candidates for corrective surgery.

To be used by optometrists and ophthalmologists, the instrument – known as the VisionOptimizer – is intended to provide more accurate vision measurements, along with a more patient-friendly and engaging vision test. The company believes its system will facilitate the custom-manufacturing of spectacles and contact lenses that provide better eyesight and improved wearing comfort compared to conventional prescriptions.

Researchers at the Georgia Institute of Technology and Bennett Aerospace are leveraging light detection and ranging (lidar) technology to develop a ground-based system that will automatically measure water vapor in the atmosphere. Known as”WaV-Pro^TM,” for Water Vapor Profiler, the system aims to provide more frequent data collection that could dramatically improve weather forecasting.

Initial work on the project began in mid-2009, when Bennett Aerospace, in collaboration with the Georgia Tech Research Institute (GTRI), won a Phase I Small Business Innovation Research grant from the National Oceanic and Atmospheric Administration (NOAA) to develop design requirements for the system. Recently, the researchers won a Phase II grant to build and test critical components needed for a final operating prototype of WaV-Pro. (more…)

Directed Energy Weapons: New System Developed to Test and Evaluate High-Energy Laser Weapons
