scheduling is to determine the priorities or arrange the activities to meet the needs, limitations and certain goals. because the time is always a limited resource, all activities should be scheduled to use optimally and certainly the resource. gravitational force algorithm, like other evolutionary algorithms, is inspired by nature. the effect of the gravity on the objects reciprocally and to a...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...
صنعت بیمه به دلیل عرضه محصول منحصر بفرد، در طبقه بندی مالی به عنوان یک صنعت با هزینه های بالا شناخته شده است. رفتار هزینه ها یک معیار مهم برای برای تعیین قدرت مالی شرکت بیمه استو این موضوع به ویژه برای بیمه گذاران و سرمایه گذاران از اهمیت اساسی برخوردار است. این مطالعه هزینه های شرکت های بیمه را در قالب سریهای زمانی پنلی انجام میدهد. تحلیل پنلی کمک برای درک رفتار نا متعارف، پیش بینی هزینه ها، و...
evaluation and modeling of the wastewater treatment plants (wwtp) have to be based on thefact that the pollutant concentrations and flow rates change constantly. in addition, different approaches mustused due to there are different processes in a wwtp. a mexican petrochemical complex has a wwtp thatprocesses wastewaters from several petrochemical plants, where the flow rates and pollutant conce...
the kaolinitic clays have been exploited for more than a hundred years, in the western part of the charentes basin, france, and belong to a paleo-deltaic network. the recent deposits are relatively richer in alumina in comparison with the older ones. the genesis of the kaolin deposits of the charentes basin follows simple geological rules, but their detailed geometry has a great complexity, rei...
