یکی از مهم‏ترین سازه‏های ارتباطی که از دیر باز مورد استفاده قرار گرفته‏اند، پل‏ها می‏باشند. مهم‏ترین عامل تهدیدکننده‏ی پایداری پل‏هایی که در مسیر جریان‏های رودخانه‏ای قرار دارند، آبشستگی پایه‏های آن ها می‏باشد. منشأ این آبشستگی‏های موضعی، فرسایشی است که در اطراف پایه‏های پل و در اثر جریان‏های گردابی به خصوص گرداب نعل اسبی ایجاد می‏گردد. مکانیزم این نوع جریان اطراف پایه پل‏ها آن‏قدر پیچیده است ک...

This paper presents an efficient hybrid algorithm for multi-objective distribution feeder reconfiguration based on Honey Bee Mating Optimization (HBMO) and fuzzy multi-objective approach. The objective functions are to minimize real power losses; deviation of nodes voltage; the number of switching operation and to balance the loads on the feeders. Due to the objectives are different and no comm...

So far, many attempts have been made to identify the relation between discharge and suspended sediment load.Empirical relations such as sediment rating curves are often applied to determine the average relationship between discharge and suspended sediment load. This type of models generally underestimates or overestimateswhen sediment load are estimated from water discharge using least squares ...

The aim of this paper is to investigate a novel approach for output feedback damping controller design of the static synchronous compensator (STATCOM) in order to enhance the damping of power system low frequency oscillations (LFO). The design of output feedback controller is considered as an optimization problem according to the time domain-based objective function solved by a honey bee mating...

Optimal placement and sizing of DG in distribution network is an optimization problem with continuous and discrete variables. Many researchers have used evolutionary methods for finding the optimal DG placement and sizing. This paper proposes a hybrid algorithm PSO&HBMO for optimal placement and sizing of distributed generation (DG) in radial distribution system to minimize the total power loss...

This paper introduces an optimal placement and tuning of robust multi-machine Power System Stabilizer (PSS) using Honey Bee Mating Optimization (HBMO). This problem is formulated as an optimization problem, which is solved using HBMO technique. Hence the proposed approach employs HBMO to search for optimal location and parameters settings of a widely used Conventional fixed-structure lead-lag P...

Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...

The main concerns of network operators is the improvement of system parameters, and various ways have been developed to achieve this goal. If the use of renewable energy including wind in the grid is used, the sustainability debate and the status of the power system parameters will be twofold. In the upcoming research, we will examine the status of the parameters by placing the Facts on the 24-...
