Description:: Software vulnerabilities that enable well-known exploit techniques for committing computer crimes are preventable, but they continue to be present in releases. When Blackhats (i.e., malicious researchers) discover these vulnerabilities they oftentimes release corresponding exploit software and...

Description:: Redundant outputs from multiple positioning systems are not typically fused together on moving vehicles, resulting in unrealized opportunities in minimizing any combined position error and uncertainty. Satellite navigation is commonly used in timing and positioning applications, and combined with...

Description:: As a result of the reuse of legacy systems by the Department of Defense (DoD), DoD programs often experience overruns and technical difficulties. With the constriction of DoD budgets, reuse of legacy systems is frequently touted as the solution to cost, efficiency, and time to delivery problems;...

Description:: Software reliability growth models (SRGMs) provide a framework to analyze software failures by using past failure data to predict future software reliability or to estimate current software reliability. Most current models use a classical approach to infer parameters and have shown limitations in...

Description:: There is an increasing backlog of potentially toxic compounds that cannot be evaluated with current animal-based approaches and models in a cost effective and expeditious manner, thus putting human health at risk. In addition, extrapolation of animal-based test results for human risk assessment...
