Balancing security and performance tradeoffs for secure Internet videoconferencing
For years, experts have predicted that ubiquitous videoconferencing was just ahead. Now, several videoconferencing trends — including improved quality, reduced cost and the economy — have fueled demand.
How do we communicate?
As a computational linguist, Ohio State University Professor Chris Brew merges computer science with the scientific study of language and communication.
Healthy forests, healthy fires, healthy bats
Do no harm. In the effort to manage the forest habitats of the endangered Indiana bat, naturalists must always, always, first consider the impact on this nocturnal mammal. Bats perform a vital ecological role, feeding entirely on flying insects; a single bat can consume thousands of mosquitoes each night.
Processing the sounds of a battlefield to evaluate targets
The sounds of war, when accurately captured and processed, shed their cacophonous echoes and leave a trail of unique, acoustical fingerprints. Much like sonar detects and classifies underwater resonance, acoustic signal processing sensors capture sounds in the air.
Benchmark study examines results of leading high-level languages
In the science and engineering community, three computer-programming languages, MATLAB, Mathematica and Python, are among the most popular. Called high-level languages, they let researchers focus on solving problems by cloaking the basic, yet necessary, coding that computers require.
