Traumatic brain injury patients, supercomputer simulations studied to improve helmets

  • PDF
These computer simulations contain a computer model of a human's head viewed from above looking down (top row) and from the side (bottom row). The images show the deposition of compressive energy in the brain during frontal, rear and side blasts. These models combined with University of New Mexico's clinical observations are being used to identify energy thresholds that should lead to better military and sports helmet designs.

TechAndComputer (Nov. 14, 2012) — Researchers at Sandia National Laboratories and the University of New Mexico are comparing supercomputer simulations of blast waves on the brain with clinical studies of veterans suffering from...

Computer science helping the aged stay home

  • PDF
TechAndComputer (Nov. 14, 2012) — University of Adelaide computer scientists are leading a project to develop novel sensor systems to help older people keep living independently and safely in their own homes.

The researchers are adapting radio-frequency identification (RFID) and sensor technologies to automatically identify and monitor human activity; to be able to determine if an individual's normal routine is being maintained so that timely assistance can be provided if it is...

TechAndComputer (Nov. 12, 2012) — The Department of Energy's Oak Ridge National Laboratory is again home to the most powerful computer in the world, according to the Top500 list, a semiannual ranking of computing systems around the world. The list was announced at this week's SC12 International Conference for High...

Data storage: How magnetic recording heats up

  • PDF
TechAndComputer (Nov. 8, 2012) — Characterization of the thermal processes involved in heat-assisted magnetic recording paves the way for commercial devices.

Most electronic data is stored on magnetic hard drives that spin at many thousands of revolutions per minute. To keep pace with ever-growing storage demand, however, achieving greater storage capacities by simply increasing the size of disks is infeasible. The required spinning speed would put immense physical strain on the...

Setting national goals to bolster patient safety with electronic health records

  • PDF
TechAndComputer (Nov. 7, 2012) — Electronic health records (EHRs) are expected to improve patient safety, but they themselves can present challenges for which health care providers must be prepared. Experts at The University of Texas Health Science Center at Houston and Baylor College of Medicine have proposed a framework to help develop new national patient safety goals unique to electronic health record-enabled clinical settings.

Their report appears in the current issue of...
