Introduction: In process industries, some of the primary events may result in secondary events in an industrial unit called the domino effect. Since refinery storage tanks are always at risk of fire and explosion, quantitative risk assessment is important in determining the severity and outcome of an accident, taking into account the effects of dominoes on the main industry, neighbors, and soci...
آنالیز خطر و ارزیابی ریسک یکی از ابزارهای مهم برای حفظ و ارتقاء سطح ایمنی در صنعت به شمار می رود. برای این منظور در واحدهای صنعتی موجود یا در حال طراحی، ارزیابی ریسک برای مخاطراتی نظیر آتش-سوزی، انفجار و یا پیامدهای مربوط به انتشار مواد سمی شیمیایی صورت می گیرد. پیشرفت صنعت و بروز حوادث مختلف در واحدهای فرآیندی که منجر به بروز فجایع انسانی و محیطی می شود، متخصصین را بر آن داشته است که برای برآو...
Background and aims: Process systems due to processed under severe operational conditions and deal with large amounts of flammable and explosive materials have always led to many catastrophic accidents. Risk assessment is a useful tool for designing effective strategies for preventing and controlling these accidents. Conventional risk assessment methods have major deficiencies, including uncert...
This paper presents a new approach to spoken document information retrieval for spontaneous speech corpora. Classical approach to this problem is the use of an automatic speech recognizer (ASR) combined with standard information retrieval techniques, based on terms or n-grams. However, state-of-the-art large vocabulary continuous ASRs produce transcripts of spontaneous speech with a word error ...
PHAST is a software package written in standard Fortran, with MPI and CUDA extensions, able to efficiently perform parallel multicanonical Monte Carlo simulations of single or multiple heteropolymeric chains, as coarse-grained models for proteins. The outcome data can be straightforwardly analyzed within its microcanonical Statistical Thermodynamics module, which allows for computing the entrop...
Integrated control strategies are important for sustainable control of schistosomiasis and soil-transmitted helminthiasis, despite their challenges for their effective implementation. With the support of Good Neighbors International in collaboration with National Institute of Medical Research, Mwanza, Tanzania, integrated control applying mass drug administration (MDA), health education using P...
Introduction: Refineries are considered as the base of many accidents and incidences due to their close proximity with dangerous substances, products, and production processes. This study analyzed the consequences of H2S leakage scenario from clot stuck unit of South Pars Gas Refinery and determined the dangerous boundaries and the risk limits of this scenario. Methods: This was a descriptiv...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
یکی از ضروری ترین و اصلی ترین مراحل برای افزایش سطح ایمنی در واحد های موجود یا در حال طراحی ارزیابی ریسک خطر هایی همچون رها شدن مواد شیمیایی در محیط است. این خطر ها ممکن است در اثر خطاهای انسانی و یا نقص تجهیزات به وجود آید. در این تحقیق، به کلیات ارزیابی ریسک و نحوه ی اعمال آن که شامل مراحلی همچون شناسایی خطرهای احتمالی در یک فرایند، مدلسازی خطرهای محتمل مانند آتش سوزی، انفجار و یا پیامد های م...
Background and purpose Many efforts have been made to use chemical components as weapons throughout history until the Germans first employed chlorine gas cylinders in April 1915 at Ypres Belgium against French and Canadian soldiers. Leaving 5,000 dead and 15,000 injured, it was the first practical application of chemical agents. The Geneva Protocol in June 1925, which was an attempt to pre...
