In this research, the factors affecting on electricity gap were examined in the electricity industry in Iran using the system dynamics approach compared to the econometric method. In the framework of the electricity gap prediction model, simulation of energy demand were investigated as well as its supply and effective factors. Analysis of the problems with these systems was very complicated bec...
this paper presents the basic concepts of stability in fuzzy linguistic models. theauthors have proposed a criterion for bibo stability analysis of fuzzy linguistic modelsassociated to linear time invariant systems [25]-[28]. this paper presents the basic concepts ofstability in the general nonlinear and linear systems. this stability analysis method is verifiedusing a benchmark system analysis.
This study deals with system integration and power management of a stand-alone renewable energy (RE) hybrid system, which is in its final stage of construction in Lambton College (Sarnia, Ontario, Canada). The system consists of five main components: photovoltaic (PV), wind turbine, electrolyzer, hydrogen storage tanks and fuel cell. The model for each process component was developed and the hy...
Fuel cell-based hybrid cycles that include conventional power generators have been created to modify energy performance and output power. In the present paper, integrated biomass gasification (IBG)-molten carbonate fuel cell (MCFC)-gas turbine (GT) and steam turbine (ST) combined power cycle is introduced as an innovative technique in terms of sustainable energy. In addition, biomass gasificati...
اخیراً مفهوم اقتصادی تراکم مورد بحث بسیاری از محققین تحلیل پوششی داده ها واقع شده است. در اقتصاد، تراکم از این بابت حائز اهمیت است که امکان افزایش خروجی ها را با کاهش ورودی ها و بدون تغییر سایر پارامترها فراهم می نماید. در این تحقیق روش های محاسبه تراکم برای واحدهای تصمیم گیری با استفاده ازمدل های dea مورد بررسی قرار گرفته و قضایای هر کدام نیز ارائه گردیده است. روشهای ارائه شده شامل fgl، bcsw،...
renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. this paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. a speed control regulator is utilized to control the dc bus voltage. the inverter gate’s signals...
this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
introduction: in single photon emission computed tomography (spect), the projection data used for image reconstruction are distorted by several factors, including attenuation and scattering of gamma rays, collimator structure, data acquisition method, organ motion, and washout of radiopharmaceuticals. all these make reconstruction of a quantitative spect image very difficult. simulation of a sp...
The main goal of this paper is to present a new day-ahead energy acquisition model for a distribution company (Disco) in a competitive electricity market environment with Interruptible Load (IL). The work formulates the Disco energy acquisition model as a bi-level optimization problem with some of real issues, and then studies and designs a Genetic Algorithm (GA) of this optimization problem to...
