Workplace safety performance is computed using frequency rate (FR) and severity rate (SR). Only work time lost due to occupational incidents that need to be reported is counted. FR and SR are the 2 most important safety performance indicators that are applied universally; however, calculations differ from country to country. All injuries and time lost should be considered while calculating safe...

24 A cornerstone of effective institutional learning and accountability is the development, tracking, and analysis of informative performance measures. In a previous issue of Fire Management Today (“A New Look at Risk Management,” Winter 2011), a series of articles highlighted the importance of organizational safety and risk management and the challenges of balancing safety, efficiency, and eff...

In this paper, we propose an algorithm for bounded safety verification for a class of hybrid systems described by metric transition systems. The algorithm combines exploration of the system trajectories and state space reduction using merging based on a bisimulation metric. The main novelty compared to an algorithm presented recently by Lerda et.al. lies in the introduction of a tuning paramete...

| Motivated by the fact that time delays in a practical Direct-Sequence Code-Division Multiple-Access system can never be perfectly estimated, an improved Minimum-Mean Squared-Error (MMSE) based receiver is proposed and analyzed. Via the simple assumption of a probability distribution for the delay estimation errors, the proposed receiver can achieve performance superior to that of the conventi...

Optimally minimizing delay times at signalized intersections can significantly improve both traffic flow and safety. However, most traffic flow optimizing tools do not measure the effect on safety. This study uses nonlinear programming (NLP) algorithms to optimally minimize delay times and employs both Safety performance functions (SPFs) and empirical Bayes (EB) before-after methodology to meas...
