This paper presents a novel methodology for safety verification of hybrid systems. For proving that all trajectories of a hybrid system do not enter an unsafe region, the proposed method uses a function of state termed a barrier certificate. The zero level set of a barrier certificate separates the unsafe region from all possible trajectories starting from a given set of initial conditions, hen...

This paper introduces incremental stability notions for a class of hybrid dynamical systems given in terms of differential equations and difference equations with state constraints. The specific class of hybrid systems considered are those that do not have consecutive jumps nor Zeno behavior. The notion of incremental asymptotic stability is used to describe the behavior of the distance between...

Objectives: Hospitals and clinical centers are concerned about patient safety. Safety climate is a perceived value of safety in an organization that could improve the safety of workers and patients. The present research was conducted to study the safety climate of patients in the hospitals and rehabilitation centers affiliated to the University of Social Welfare and Rehabilitation Sciences.  M...

Introduction: A childs world centers around the home, school and the local community. These should be healthy places. But in reality, these places are often so unhealthy that they underlie majority of accident and disease among children in the developing world. The aim of this study was to determine ergonomic, safety and environmental health status at primary schools in Markazi province. Materi...

In this report, a new interpretation of the main part of our study on asymptotic behaviour of reduced-order lters in 6] is given. Approximate lters are proposed for semi-linear and nonlinear stochastic systems with colored noises. Basically these lters are deened as those which are optimal when the noises are white. Their long time behavior is investigated and their asymp-totic optimality is sh...
