Electrocardiogram (ECG) Signal Modeling and Noise Reduction Using Hopfield Neural Networks
Journal Title: Engineering, Technology & Applied Science Research - Year 2013, Vol 3, Issue 1
Abstract
The Electrocardiogram (ECG) signal is one of the diagnosing approaches to detect heart disease. In this study the Hopfield Neural Network (HNN) is applied and proposed for ECG signal modeling and noise reduction. The Hopfield Neural Network (HNN) is a recurrent neural network that stores the information in a dynamic stable pattern. This algorithm retrieves a pattern stored in memory in response to the presentation of an incomplete or noisy version of that pattern. Computer simulation results show that this method can successfully model the ECG signal and remove high-frequency noise.

Improving Power System Stability Using Transfer Function: A Comparative Analysis
In this paper, a small-signal dynamic model of a single-machine infinite-bus (SMIB) power system that includes IEEE type-ST1 excitation system and PSS based on transfer function structure is presented. The changes in the...
A Compact Tri-Band Bandpass Filter with High Out-of-Band Rejection
This paper presents a planar tri-band bandpass filter with high out-of-band rejection over a wide band. The filter is based on two pairs of λ/4 resonators embedded inside an open loop ring resonator without any size incr...
Investigation of the Behavior of Steel Shear Walls Using Finite Elements Analysis
Currently, steel shear walls are considered by engineers as an economic method against lateral loads imposed by wind and earthquake in tall structures. Accordingly, there is a growing need to develop accurate methods alo...
