Robust Control Design for Multi Variable Singular Perturbation Systems
Volume 3, Issue 3 , March 2009, Pages 1-8
Abstract
In this paper the robust control of multi variable singular perturbation systems is studied. In order to robust the control of the system, only the additive modeling error is considered. Based on the above bounds of modeling error and the Nyquist criteria and in order to improve the performance of the ... Read MoreCharacterization of Fabricated Photonic Crystal Fibers Using Effective Index Method
Volume 3, Issue 3 , March 2009, Pages 9-19
Abstract
In this paper, the characteristics of photonic crystal fibers (PCFs), which have been experimentally determined in the last few years in Iran's Telecom Research Center are analyzed and compared theoretically using an effective index method. The PCFs under investigation are fabricated with a high speed ... Read MorePerformance Analysis of an Image Watermarking Approach Based on Sample Rotation with Wavelet Transformation
Volume 3, Issue 3 , March 2009, Pages 21-32
Abstract
This paper presents a simple watermarking approach based on the rotation of low frequency components in image blocks. The rotation process is performed with less distortion by projecting the samples on specific lines according to their message bit. To optimize the detection, the Maximum Likelihood ... Read MoreECG Signals Classification Based on Wavelet Transform and Probabilistic Neural Networks
Volume 3, Issue 3 , March 2009, Pages 33-40
Abstract
In this paper a very intelligent tool with low computational complexity is presented for Electroencephalogram (ECG) signal classification. The proposed classifier is based on Discrete Wavelet Transform (DWT) and Probabilistic Neural Network (PNN). The novelty of this approach is that signal statistics, ... Read MoreThe Optimal Locating of Power Controller in Transmission Line With Consideration of Optimal Power Flow
Volume 3, Issue 3 , March 2009, Pages 41-52
Abstract
In this paper two power elements for power controller in transmission line are presented: Variable Frequency Transformer (VFT) and Rotary Power Flow Controller (RPFC). In addition, here a new Optimal Power Flow (OPF) with these elements is presented. In this paper, it has been made use of the Impedance ... Read MoreA New Segmentation Method for Persian/Arabic OCR Based on Baseline Processing
Volume 3, Issue 3 , March 2009, Pages 53-61
Abstract
One of the most important stages in Character Recognition Systems is “Segmentation”, because any mistake will affect to all other tasks, especially to character recognition. This operation is more complex in Persian/Arabic writing than other Latin writing like English, and there has been an ongoing ... Read MoreAn Improved Adaptive Genetic Algorithm for Job Scheduling Problem on Parallel Robots
Volume 3, Issue 3 , March 2009, Pages 63-70
Abstract
Minimizing mean tardiness by Job scheduling on parallel robots is very important in the scheduling domain. In this problem, there is a series of n-number independent jobs which are ready to be scheduled at the time of zero. Corresponding to each work, the processing time and duration date are determined. ...
