Parents' awareness and performance plays a key role in food safety of the children. This study aimed to investigate the relationship between parents’ awareness and performance regarding food security with anthropometric indices in school-age children from Bushehr, Iran, during 2017. Data in this descriptive-analytical study was collected from 402 parents using questionnaires on awareness and pe...

If our goal is to improve safety through machine, interface, and training design, then we must define a metric of flightdeck safety that is usable in the design process. Current measures associated with our notions of "good" pilot performance and ultimate safety of flightdeck performance fail to provide an adequate index of safe flightdeck performance for design evaluation purposes. The goal of...

In this paper, an analytic model is proposed for performance evaluation of vehicular safety related services in dedicated short range communications (DSRC) system on highway. The generation and service of safety messages in each vehicle is modeled by an M/G/1 queue. But since vehicles share a medium, the service time distribution of a message needs to take contention and backoff into account. W...

This study aimed to determine the proportion of Australian farming enterprises with systems and processes that meet current regulatory and industry standards for health and safety. Data from 683 farming enterprises were drawn from a nationally stratified random sample representing seven commodity sectors: beef cattle, cotton, dairy, horticulture, grain growing, sheep, and sugar cane. Results in...

Compositional Stability, Performance, and Safety Certification of Interconnected Systems by Christopher Ryan Meissen Doctor of Philosophy in Engineering Mechanical Engineering University of California, Berkeley Professor Andrew Packard, Chair Modern computational tools for stability, performance, and safety certification are not scalable to large nonlinear systems. In this dissertation we propo...

The growing importance of real-time computing in numerous applications poses problems for network architectures, especially safety-critical Wide Area Networks (WANs). Assessing network performance in safety-critical real-time systems is difficult, and suggests the use of both human and technical performance criteria because of the importance of both dimensions in safety-critical settings. This ...
