A method for concurrent clearing of energy and reserve market is presented in this paper. The proposed method considers two important objectives in an optimization problem; the first one is including the stochastic nature of power generation variations by applying a probabilistic clearing model and Monte-Carlo simulation; the second one is assignment of energy and reserve capacities to generati...

 Commonly in designing hydroelectric dams and in the level of consulting engineers, for determining the hydroelectric potential of an storage, the analyze is done based on an RBS (Reliability Based Simulation) model with an obvious operation policy.   In this paper the effect of optimizing release rules instead of using a fixed and know release policy, like what it is adopted in an RBS model, w...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...

there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
