Given a target probability of functional failure on demand for a system, a corresponding dangerous failure rate for the system can be derived, provided that a proof-test interval for the function is known. IEC 61508, and related standards, requires that this calculation be performed, for certain kinds of systems that are required to provide safety functionality on demand. This paper explains wh...
In this tool demonstration, we give an overview of the Chameleon type debugger. The type debugger’s primary use is to identify locations within a source program which are involved in a type error. By further examining these (potentially) problematic program locations, users gain a better understanding of their program and are able to work towards the actual mistake which was the cause of the ty...
Background and aims: Disasters and Events including Natural and man-made disasters, Caused several harmful consequences in society. Health sector has an Essential role in Reducing deaths and injuries during disasters. Therefore present study with aim of Disaster Safety and Risk Assessment in Primary Health Care Facilities of Iran University of Medical Sciences in Functional, Non Structural & St...
Background and Objectives: The necessity of assessing safety in hospitals lies with the fact that although accidents are rare, they impose considerable financial loads on hospital. Along with examining the risks, the managers of hospitals need to improve their capabilities and standards and reduce the hazards caused by accidents. The present study is aimed at assessing fu...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Introduction: Hospital preparedness for accidents and disasters is vital in maintaining and promoting community health. However, the country's hospitals are not well prepared for disasters. The hospital safety index (HIS) was 42% in Iranian hospitals in 2014. This study aims to investigate the HSI in Iranian hospitals in 2020 and to provide solutions to improve it. Methods: This cross-sectiona...
Whereas current engineering practice focuses on functional requirements, considerations other than the function (e.g., safety; security; maintainability) are relegated into a category (unfortunately) called “non-functional requirements.” Although ISO/IEC/ IEEE 24765 §3.1900 defines this term as “a software requirement that describes not what the software will do but how the software will do it,...
Introduction and purpose: Crisis is an environmental and sudden phenomenon and it is so severe that it requires the assistance of local out of the crisis for the accountability and the management. The hospital is one of the most important components of health and treatment collection and its performance in accordance with a set of other factors led to the health care of the community. During th...
