Distributed generation (DG) has been widely used in distribution network to reduce the energy losses, improve voltage profile and system reliability, etc. The location and capacity of DG units can influence on probability of protection mal-operation in distribution networks. In this paper, a novel model for DG planning is proposed to find the optimum DG location and sizing in radial distr...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Cryogen spray cooling (CSC) protects the epidermal layer during dermatologic laser surgery (DLS) of superficial vascular lesions. Because of spray characteristics the protection provided radially is relatively uniform only by the spray axis. The present work explores mass-deposition passive-control during CSC in order to increase the radial homogeneity of heat extraction. A stainless steel mesh...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
BACKGROUND Reconstruction after partial cricotracheal resection is technically demanding and is seldom reported in literature. The purpose of this study was to report a technique of reconstruction of such a defect with a radial forearm flap supported by a titanium mesh. METHODS A 75-year-old man who was diagnosed with a case of papillary carcinoma thyroid, underwent excision of the tumor with...
In this paper we compare the Wolf method to the shifted forces (SF) method for efficient computer simulation of bulk systems with Coulomb forces, taking results from the Ewald summation and particle mesh Ewald methods as representing the true behavior. We find that for the Hansen-McDonald molten salt model the SF approximation overall reproduces the structural and dynamical properties as accura...
Introduction: This study presents an effective method with high stability called the coyote optimization algorithm (COA) for optimal integration of renewable distributed generation units (DGUs), including biomass (BMs), wind turbine (WTs) and photovoltaic (PVs). The main aim is to minimize annual power loss cost considering three hybrid systems combination PV WT, BM PV, WT in time-varying load ...
