A methodology to quantify risk of failure for dynamic robots
Humans possess an innate sense of danger that guides the execution of extraordinary dynamic maneuvers. They can also use this sense to generate creative recovery strategies to eventually come to a safe stop. This capability is not yet available to robots, fundamentally because there is no clear …

Time varying probability of failure of steel floor beams subjected to real fire
… for estimating the time-dependent reliability of steel beams under real fire conditions has been developed. It gives a more rational basis than time of failure modelling does for design. From risk modelling, some small resistance time from the probabilistic distribution times of failure can be …

Risk assessment models for resource failure in grid computing
… are not keen to adopt SLAs since there is a risk of SLA violation as a result of resource failure, which will result in a penalty fee; therefore, the need to model the resources risk of failure is critical to Grid resource providers. Essentially, moving from the best-effort approach for …

Condition Assessment, Indices, and Risk-based Decision-making for Public School Infrastructure Management
… material assets. In addition, the manufacturing of lead based paint (LBP) was banned over thirty years ago yet public schools continue to have to manage LBP assets with no guidelines specific to public schools. When compared to current civil infrastructure asset management systems, AHERA and the …

Manufacturability of lab on a chip devices: tolerance analysis and requirements establishment
Decisions made during the first stages of the design process can have an impact on the cost, quality and performance of a product. Variation in assemblies, if not managed correctly during the design stage, can have a negative impact on the success of the product. This work analyzes the Daktari CD4+ …
