This paper describes a systematic and multidisciplinary approach to developing evidence-based standards and guidelines of user interface design for mobile survey instruments. The approach includes five major components: project team, systematic literature review, mobile user model, standards development, and guidelines development. A multidisciplinary project team was assembled to ensure adequa...

background : due to specific conditions in hospitals such as accumulation, existence of disable persons and patients, different and complex equipment, chemical and infectious substances, flammable materials and ionized radiations, safety precautions is essential to prevent the occurrence of incidents such as fire, electric shock hazard and exposure to excessive levels in hospitals. this was the...

This study presents the manner in which transient modeling concepts, which are fully analyzed in the referred standards, are implemented, for the purpose of evaluating the Transient Ground Potential Rise (TGPR). This is a phenomenon of 10–100kV voltages with up to 10μs duration on the grounded enclosure of Gas Insulated Substations (GIS), which may cause concern for personnel safety and problem...

H igh-assurance systems are used in environments where failure can cause security breaches or even a loss of life [1]. Examples include avionics, weapon controls, intelligence gathering, and life-support systems. Before such a system can be deployed, there must exist convincing evidence that it can support critical safety as well as security properties. The avionics community has addressed the ...
