– Fixed broadband microwave communications are usually considered line-of-sight (LOS) technologies. Conventional wisdom holds that non-line-of-sight (NLOS) paths are of insufficient quality for broadband commercial deployments. However, it is possible that the only links available in an emergency deployment are NLOS paths. Since little work has been(More)
As part of the project " Testbed for High-Speed End-to-End Communications in Support of Comprehensive Emergency Management " funded by the National Science Foundation's Digital Government Program (award EIA-9983463), Virginia Tech researchers are developing a prototype system to provide a high-speed backbone network for emergency and disaster response.

The individual pursuit is a 4-km cycling time trial performed on a velodrome. Parathletes with transtibial amputation (TTA) have lost physiological systems, but this may be offset by the reduced aerodynamic drag of the prosthesis. This research was performed to understand the effect of a unilateral TTA on Olympic 4-km pursuit performance. A(More)
