Research ArticleOpen accessIn the author namesSeismic Response Evaluation of Moment Resistant Frame with Built-Up Column SectionMohammad Ebrahimi, Hesam Sharifian, Mohammad AhangarProblem statement: Moment Resisting Frame (MRF) is widely used as lateral resisting systems when sufficient ductility and deformability are to be met. Response of these structures is strictly dependent upon behavior of their joints, whereas the analysis of steel moment resisting frames generally has been performed without considering the accurate connection behavior. Approach: In this study Finite Element (FE) models … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,289 accessesView PDFCite
Research ArticleOpen accessIn the author namesImplementing a Vector Controller Using 68k ProcessorsMohammad Bagher, Bannae Sharifian, Mohammad Reza Feyzi et al.Problem statement: This study described the design of a 3-phase AC Induction Motor (ACIM) vector control drive with position encoder coupled to the motor shaft. Approach: It was based on free scale's (Motorola's) 68k micro processor devices. Although the free scale 56F80x (56800 core) and 56F8300 (56800E core) families were well-suited for digital motor control and offer all things was … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,690 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Novel Method for Optimal Location and Expansion of Subtransmission Substations Considering Existing Medium-Voltage Distribution FeedersM. Farrokhifar, M. Bana Sharifian, R. EsmaeilzadehThis research presents an accurate comprehensive cost function for the problem of optimal location of subtransmission substations. Technical constraints and economical parameters are investigated in the modeling. Genetic algorithm is used to optimize the cost function. Coding of decision variables is done in a way that finding the correct solutions is achieved faster. For the first time in this study, … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,793 accessesView PDFCite
Research ArticleOpen accessIn the author namesMagnetic and Thermal Analysis of Current Transformer in Normal and Abnormal ConditionsM. B.B. Sharifian, M. Farrokhifar, R. Esmaeilzadeh et al.Calculation of Current Transformers (CTs) magnetic and thermal properties are very complex due to the complexity of their construction, different properties of their materials and non-linearity of core B-H curve. Finite Element Methods (FEMs) are very capable and reliable methods for these problems solution, such as Ansys software. In this study Ansys software is applied in analysis of an 800-400/5-5 … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,042 accessesView PDFCite
Research ArticleOpen accessIn the author namesComputation of a Single-phase Shell-Type Transformer Windings Forces Caused by Inrush and Short-circuit CurrentsM. B.B. Sharifian, R. Esmaeilzadeh, M. Farrokhifar et al.This research studies the forces on the windings of transformer due to inrush current. These forces are compared with the corresponding forces due to short-circuit of the windings. Two-dimensional finite element computation of a single-phase shell-type transformer is carried out based on the maximum permissible inrush current value where its amplitude is the same as the rated short-circuit current. To … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 7,437 accessesView PDFCite
