This paper presents a new Hybrid Particle Swarm optimization with Time Varying Acceleration Coefficients (HPSOTVAC) and Bacteria Foraging Algorithm (BFA) namely (PSOTVAC/BFA) base fuzzy stochastic long term approach for determining optimum location and size of Distributed Energy Resources (DERs). The Monte Carlo simulation method is used to model the uncertainties associated with long-term load...

In distribution networks, failure to smooth the load curve leads to voltage drop and power quality loss. In this regard, electric vehicle batteries can be used to smooth the load curve. However, to persuade vehicle owners to share their vehicle batteries, we must also consider the owners' profits. A challenging problem is that existing methods do not take into account the vehicle owner demands ...

L ifestyle changes, in particular reducing energy intake, are the cornerstone of current approaches to weight loss and prevention of type 2 diabetes. However, there is currently no consensus that one dietary regimen is more effective than another for weight loss (1) or whether particular diets work better for identifiable groups of individuals. There is evidence, however, to suggest that both i...

The geometric shape of dental arch (square, tapering, ovoid) is an important factor in stress distribution pattern around dental implant. The aim of this study was to evaluate the role of arch form and the amount of bone loss (normal, moderate, high) in stress distribution around dental implant by considering different load direction. Three arch forms square, ovoid, and tapering with three diff...

Background and Aim: Clinical guidelines are categorized and provide information in order to help the decision-making of medical teams, with the aim of improving patients care. Therefore, this study aims to identify the factors influencing the implementation of clinical guidelines in Iran. Methods: This is a descriptive-analytical study performed in 2018‒2019. The study population consisted of m...

Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation r...

با توجه به اهمیت مسأله کاهش اقتصادی تلفات که تحقیقات زیادی در خصوص بهینه کردن آن صورت گرفته، هدف این پروژه کاهش اقتصادی تلفات در شبکه توزیع واقعی می باشد. جهت نیل به هدف در این تحقیق به چگونگی تعیین مقدار و جایابی بهینه بانکهای خازنی با در نظرگرفتن نامتعادلی بار و نیز چگونگی انتخاب مقدار سطح مقطع هادیها در خطوط توزیع در شبکه های توزیع شعاعی پرداخته شده است. روش کار بدین صورت است که دو فیدر 20 ک...

Erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. These erosion plots with an area of 40 m2 are located in the Kakhk experimental watershed in Gonabad County of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy...
