Log-structured applications and file systems have been used to achieve high write throughput by sequentializing writes. Flash-based storage systems, due to flash memory’s out-of-place update characteristic, have also relied on log-structured approaches. Our work investigates the impacts to performance and endurance in flash when multiple layers of log-structured applications and file systems ar...

Every 6 seconds someone is killed or seriously injured on the world's roads. With 1.3 million road deaths each year this is a global epidemic comparable to malaria or Tuberculosis. Nine in ten road deaths and injuries are in developing countries. By comparison to other global killers, road injury is neglected. Road crashes are the leading global cause of death for young people under 25 years, a...

Vehicle-to-Vehicle (V2V) communication channel measurements were carried out in different environments such as urban, suburban, rural, highway, tunnel, and overpass. The roads these have generally flat terrain. However, there are horizontal or vertical curve that been little focused the literature. In this study, we performed two V2V on a vertical-curve road rural environment to show how receiv...

Ensuring safety on roadways and controlling conflicting merging streams of traffic at signalized intersections has become a major concern for transportation engineers road users globally locally. Many factors contribute to accident occurrence segments with driver behavior being the contributor.  Other include those related vehicle road. The primary aim this study is understand impact diffe...
