acknowledgements i wish to express my gratitude to all those who have helped me in preparing this thesis. i would like to express my deep gratitude to my respected advisor dr. kourosh akef, whose advice and comments helped me in the early stages of the research and throughout the writing process. i would also like to express my gratitude to dr. hajar khanmohammad whose invaluable guidance he...
An epidemic model with optimal control strategies was investigated for Hepatitus C Viral disease that can be transmitted through infected individuals. In this study, we used a deterministic compartmental model for assessing the effect of different optimal control strategies for controlling the spread of Hepatitus C disease in the community. Stability theory of differential equations is us...
In this paper we describe a perfect simulation algorithm for the stableM/G/c queue. Sigman (2011: Exact Simulation of the Stationary Distribution of the FIFO M/G/c Queue. Journal of Applied Probability, 48A, 209–213) showed how to build a dominated CFTP algorithm for perfect simulation of the super-stable M/G/c queue operating under First Come First Served discipline, with dominating process pr...
در این کار تحقیقاتی هفت ترکیب به فرمول های شیمیایی زیر تهیه شده و مورد مطالعه قرار گرفته است: [bah]4[(pydch)2(pydc)].pydch2 (1) 4h20 .](h2o)(oh)(pydc)(pydch2)ca][3(pydch)ca][2-meimh2] (2) [in(pydc)(h2o)3]2.pydch2 (3) [sb(pydc)(pydch)(h2o)] (4) [bah]2[zr(pydc)3]. h2o (5) [d-meamh][in(pydc)2(h2o)2] (6) [1-meimh][ca(pydch2)(pydc)(h2o)2][ca(pydch)3].4h2o(7) ترکیب (1) محصول واکنش ترکیب...
اخیرأ، کدهای بر روی حلقه های متناهی توجه زیادی را به خود جلب کرده است. یک مجموعه $ -n $تایی بر روی حلقه ی $ r $ را یک کد خطی بر روی $ r $ گویند هرگاه یک $ -r $مدول باشد. یک کد دوری بر روی حلقه ی $ r $ از طول $ n $، یک کد خطی است با این شرط که اگر $ (c_0, c_1, ldots, c_{n-1}) in c$ آن گاه $ (c_{n-1}, c_0, ldots, c_{n-2}) in c$. کدهای دوری ایده آل های حلقه ی $ r_{...
The present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. The design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. Once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables....
Background: clean room is an environment fully enclosed where parameters such as airborne particles under control and is requirement in the pharmaceutical industries to produce quality products. The aim of this study was to assessment and simulation of airflow and particle of clean room by CFD method in a pharmaceutical industry. Materials and Methods: This study used an experimental study tha...
background & aim: self-confidence, as one of the key elements of clinical competence, plays an important role in one’s actions and behaviours. selection of proper instructional methods influences students’ self-confidence. therefore, this study aimed to compare the effects of web-based training and educational simulation on midwifery students’ self-confidence in postpartum hemorrhage managemen...
this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...
In this study, the effects of linear and rotational speed of the friction stir welding tool was investigated on the heat generation and distribution at surface and inside of workpiece, material flow and geometry of the welding area of poly methyl methacrylate (PMMA) workpiece. The commercial CFD Fluent 6.4 software was used to simulation of the process with computational fluid dynamic technique...
