objectives : to develop a clear criteria for classifying the patients in triage unit of a tertiary healthcare center according to five-level triage system. methods : this study is a qualitative study being conducted in five stages at vali-asr hospital of qom in 2013. after two survey, the experts were interviewed using focus group discussion (fdg) and study was continue with. data were analyzed...
This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...
Numerical models of underwater sound propagation predict the energy of impulsive signals and its decay with range with a better accuracy than the peak pressure. A semi-empirical formula is suggested to predict the peak pressure of man-made impulsive signals based on numerical predictions of their energy. The approach discussed by Galindo-Romero, Lippert, and Gavrilov [J. Acoust. Soc. Am. 138, i...
Fine-grained categorization can benefit from part-based features which reveal subtle visual differences between object categories. Handcrafted features have been widely used for part detection and classification. Although a recent trend seeks to learn such features automatically using powerful deep learning models such as convolutional neural networks (CNN), their training and possibly also tes...
In visual crowding, identification of a peripheral object is impaired by nearby objects. Recent studies have demonstrated that crowding is not limited only to interaction between low-level features or parts, as presumed by most models of crowding, but can also occur between high-level, configural representations of objects. In this study we show that the relative strength of crowding at the par...
در این پایان نامه، جریان دوفازی حباب هوا در یک سیال لزج با استفاده از روش level set به صورت دوبعدی مدل سازی شده است. مدل فیزیکی مساله شامل کانالی مستطیل شکل می باشد که اضلاع آن در جهت های افقی و عمودی به ترتیب سه و ده برابر قطر حباب مورد مطالعه است. جریان های دو فاز آرام فرض شده و در هر چهار جداره کانال مستطیلی، شرط مرزی دیواره درنظر گرفته شده است. شکل اولیه حباب در تمامی حالات به صورت دایره فر...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
جریان های سطح آزاد در مسائل مختلف مهندسی نظیر، کاویتاسیون و چوشش و حرکت رودخانه ها و دریاچه ها و دریاها کاربرد دارد. کارهای زیادی چه تحلیلی و چه آزمایشگاهی یا عددی بر روی این دسته از جریان ها انجام شده که اولین آن به کار یانگ و لاپلاس بر می گردد. به علت پیچیدگی های موجود در این دسته از مسائل (که شامل تغییر شکل سطح و یا تقسیم شدن آن و یا تاثیرات غیر خطی و انتقال جرم و حرارت و غیره است) کارهای تح...
