Clustering of ECG Signals Based on Fuzzy Neural Network with Initial Weights Generated by Genetic Algorithm

Elaheh Sayari; Mahdi Yaghoobi

Volume 8, Issue 1 , March 2014, Pages 1-9

Abstract
  Early detection of heart diseases/abnormalities can prolong life and enhance the quality of living through appropriate treatment. Whereas clustering of electrocardiogram (ECG) signals will help to identification of heart diseases as soon as possible. In this regard, neural network and fuzzy logic have ...  Read More

Applying GA for Optimizing the User Query in Image and Video Retrieval

Ehsan Lotfi

Volume 8, Issue 1 , March 2014, Pages 11-18

Abstract
  In information retrieval systems, queries may be based on user sketches. The new method presented here, optimizes the user sketch before implementation. This optimization may be used in Content-Based Image Retrieval (CBIR) and Content-Based Video Retrieval (CBVR) which is based on trajectory extraction. ...  Read More

Automatic Prostate Segmentation in Ultrasound Images using GVF Active Contour

Bahram Dehghan; Ahad Salimi

Volume 8, Issue 1 , March 2014, Pages 19-26

Abstract
  Prostate cancer is one of the leading causes of death by cancer among men in the world. Ultrasonography is said to be the safest technique in medical imaging so it is used extensively in prostate cancer detection. In the other hand determining of prostate’s boundary in TRUS (Transrectal Ultrasound) ...  Read More

New Power Losses Allocation Method Based on the Decomposition of the Network Matrix and the Voltage Regulation at Network Nodes

Tchuidjan Roger; Hamandjoda Oumarou; Mbobda Gérard; Tabe Moses; Henguert otto

Volume 8, Issue 1 , March 2014, Pages 27-35

Abstract
  In the modern context of electricity market deregulation, the price of the kilowatt-hour must take both power injections and withdrawals of the multiple market participants into consideration, as well as their actual grid usage. The responsibility for causing transmission losses and voltage drops therefore ...  Read More

Multi-Dimensional Fuzzy C-Mean Considering Spatial Information for Brain MRI Segmentation

Jamal Ghasemi; Mohammad Reza Karami Mollaei; Reza Ghaderi; Ali Hojjatoleslami

Volume 8, Issue 1 , March 2014, Pages 37-44

Abstract
  Due to artifacts, brain magnetic resonance image (MRI) segmentation is a complicated concern. This research work presents an image segmentation approach for brain magnetic resonance (MR) images. The proposed method is based on multi dimensional fuzzy C-mean. In this technique, different features of neighbouring ...  Read More

Design a of 3-Dimensional Nonlinear Optimal Robust Guidance Law for Homing Missiles against Maneuvering Targets using Genetic Algorithm

Seyed Hamze Moosapour; Ghasem Alizadeh

Volume 8, Issue 1 , March 2014, Pages 45-51

Abstract
  Optimal sliding mode guidance (OSMG) law is proposed for tactical missiles pursuing maneuvering targets in three-dimensional space. The most important characteristic of sliding mode control (SMC) is high robustness against parameter variations or external disturbances. Using a Lyapunov function, it is ...  Read More

Evaluation of 1-phase, 3-phase and Lightning Faults on Wind Farms using EMTP-RV

Saber Arabi Nowdeh; Mohsen Chitsaz; Saheb Khanabdal

Volume 8, Issue 1 , March 2014, Pages 53-61

Abstract
  Since development of wind power plants installation is growing, problems related to network connecting, stability and voltage effects become more important. On the other hand, wind farms are often open to lightning because of their long height and specific appearance. In this paper modeling and simulation ...  Read More

Digital Watermarking Based on Contourlet-SVD

Seyedeh Akram Hosseini; Sedigheh Ghofrani

Volume 8, Issue 1 , March 2014, Pages 63-68

Abstract
  in this paper, embedding a watermark image is performed in discrete Contourlet transform (CT) domain. It is known that the CT is able to capture the directional edges and contours superior to discrete wavelet transform. The proposed scheme is based on embedding watermark bits into the singular value ...  Read More

Optimal Reactive Power Dispatch using Improved Differential Evolution Algorithm

Hamid Falaghi; Arsalan Najafi

Volume 8, Issue 1 , March 2014, Pages 69-78

Abstract
  Reactive power dispatch plays a key role in secure and economic operation of power systems. Optimal reactive power dispatch (ORPD) is a non-linear optimization problem which includes both continues and discrete variables. Due to complex characteristics, heuristic and evolutionary based optimization approaches ...  Read More

An Investigation in the I-gate Body Contact for Partially Depleted SOI MOSFET

Arash Daghighi; Hassan Rafiei

Volume 8, Issue 1 , March 2014, Pages 87-91

Abstract
  In this paper for the first time, a circuit model for multi-finger I-gate body-contacted silicon-on-insulator MOSFET is presented. The model parameters are adjusted using simulation of a 45 nm SOI nMOSFET. Using the model, typical body voltage for a 35 finger device is obtained and applied to the transistor. ...  Read More
