Detection of Acute Atrial-Ventricular Arrhythmias Based on ECG Delineator: Evaluation on MIT/BIH Standard Databases

AbstractIn this paper we use an efficient arrhythmia algorithm based on wavelet transform. In first step, QRS complexes are detected. Then each QRS is delineated by detecting and identifying the peaks of the individual waves, complex onset and end. Then the determination of P and T wave peaks, onset and ends are performed. Finally the […]

Networked Control System Simulation Methods:A Comparative Study

In this paper, we examine several frameworks for NCS simulation: a MATLAB-based package called True Time, the Agent/Plant addition to the ns-2 network simulator, and other MATLAB -based frameworks. We analyze the accuracy, speed, and ease of use of two different methods of simulating system dynamics using the Agent/Plant extension to ns-2. We also introduce […]

Synthesis of a Logic-Based Switching H2/H∞ Controller:A Fuzzy Supervisor Approach

In this paper, the synthesis of switching H2/H∞ controller is considered which achieves a minimum bound on the H2 performance level, while satisfying the H∞ performance. The proposed hybrid control scheme is based on a fuzzy supervisor which manages the combination of controllers. A convex formulation of the two controllers leads to a structure which […]

A New Hybrid Watermarking Algorithm for Images in Frequency Domain

In recent years, digital watermarking has become a popular technique for digital images by hiding secret information which can protect the copyright. The goal of this paper is to develop a hybrid watermarking algorithm. This algorithm used DCT coefficient and DWT coefficient to embedding watermark, and the extracting procedure is blind. The proposed approach is […]

Sensorless Speed Control of Induction Motors with DTC Based on EKF

Considering the wide usage of induction motors in various industries and the limitation of applying speed sensors in some cases, sensorless drives have became very important and the challenge to increase the accuracy of estimation  continues. This paper presents a novel method for sensorless speed control for IM’s that not only improve the estimation and […]

Control Power Flow in the Presence of Distributed Generators Using Unified Power Flow Controller

In this paper  the power flow control at power systems in the presence of distributed generation is analyzed. The work proposes use ofUnified power flow controller (UPFC) tocontrol the  power flow at the load bus by Main supply in coordination with DG source. This work shows that using UPFC leads to the reduction of the […]

Coronary Artery Detection in X-Ray Angiogram with Fuzzy C-means Clustering Algorithm

This paper presents an algorithm for the segmentation of Blood Vessels from x-ray angiography of coronary artery images using Matched filters and Otsu thresholding. Identifying these arteries is a difficult process because of the vessel overlapping, and superimposition with various anatomical structures such as the ribs, the spine and the heart chambers. Firstly, the 3D […]

A Novel CMOS Ripple Comparator Cell Using the Gate-Diffusion Input Technique

In this paper a new implementation of CMOS ripple comparator cell using the Gate-Diffusion Input (GDI) technique is presented. The proposed design using this technique allows for the reduction of power consumption, propagation delay, and the area of digital circuits while maintaining low complexity of logical design. The performance comparison with standard CMOS and GDI […]

Investigation of Temperature Effects in 45nm Silicon-on-Diamond MOSFET Transistor

In this paper, the self-heating effects (SHE) in 45nm Silicon-on-Insulator (SOI) and Silicon-on-Diamond (SOD) are investigated. As a result of the high thermal conductivity of diamond, SHE is much less pronounced in SOD structures. This makes SOD transistors suitable for high power applications were large power density is required. Our hydrodynamic simulation results show that […]
