Today, the equipment of electronic communication networks (EECN) consists two interconnected components. The first is hardware, second software, normal functioning each which depends on network in general. One main concepts characterizing network's ability to perform tasks as intended functional safety (FS). This concept similar reliability, but differs mainly that context all possible failure ...

Modern automobiles have evolved from just being mechanical machines to having full-fledged electronics systems that enhance vehicle dynamics and driver experience. However, these complex hardware software systems, if not properly designed, can experience failures compromise the safety of vehicle, its occupants, surrounding environment. For example, a system activate brakes avoid collision saves...

conclusions we observed acceptable results regarding both efficacy and safety with 62.5 mg of bosentan, twice daily in this group of patients. further clinical trials investigating pah with lower dosages of bosentan may be warranted. results no adverse drug reaction was observed during the follow-up. clinical worsening occurred in six (14%) patients, at least one year after treatment, two of th...

In the automotive domain, there is currently no formal requirement to produce an explicit safety case. Instead the implicit safety case for a vehicle is comprised of compliance with extensive national and international regulation and standards. With the imminent introduction of the automotive functional safety standard ISO 26262, the production of a functional safety case is now a requirement f...

Introduction A growing level of attention has recently been given to the automated control of potentially hazardous processes such as the overpressure or containment of dangerous substances. Several independent protection methods provide measures to reduce the risk from such hazards to personnel, the environment and assets. A significant level of this risk reduction is allocated to safety instr...

background: to increase safety of patients and staffs in hospitals, safety standards and regulations must be considered. this study was conducted to evaluate safety conditions in hospitals affiliated to kerman university of medical sciences.   methods: this cross-sectional descriptive study was conducted in various wards and units of four hospitals affiliated to kerman university of medical sci...

This paper presents a methodology for achieving functional safety for an automated driving system (SAE Level 4) with respect to safe transitions between the driver and the system. Safety analysis and assessment of an implementation example show how to allocate safety requirements on HumanMachine Interface (HMI) components to handle the risks of unfair transition, mode confusion and stuck in tra...
