Social Takaful consists of two sections. The first one is “Public Takaful” (Takaful Aamm). It is based on the responsibility of individuals in the society to be concerned about the other’s needs and to fulfill their needs in a viable way. The other category of social Takaful is Zeman Ealah (Sustenan... ادامه

In this study, the discharge coefficient of sharp-crested weirs located on circular channels was modeled using the ANFIS and ANFIS-Firefly (ANFIS-FA) algorithm. Also, the Monte Carlo simulations (MCs) were used to enhance the compatibilities of the soft computing models. However, the k-fold cross va... ادامه

نویسندگان: Farboudfam N., NOURANI V., AMINNEJAD B.
Due to the need to simulate rainfall time series at different time scales for engineering purposes on one hand and lack of recordings for these parameters in small scales caused by the administrative and financial problems, on the other hand, disaggregation of rainfall time series to the desired sca... ادامه

Ships play the major role in bulk transportation and they need their special energy system. This paper proposes a stochastic programming method for optimal sizing of a hybrid ship power system with energy storage system (ESS), photovoltaic power (PV) and diesel generator. To account for uncertaintie... ادامه
