[ 1 ] - Heart Rate Variability Classification using Support Vector Machine and Genetic Algorithm
Background: Electrocardiogram (ECG) is defined as an electrical signal, which represents cardiac activity. Heart rate variability (HRV) as the variation of interval between two consecutive heartbeats represents the balance between the sympathetic and parasympathetic branches of the autonomic nervous system.Objective: In this study, we aimed to evaluate the efficiency of discrete wavelet transfo...
[ 2 ] - The Usability and Efficiency Human-Computer Interface in Cervical Spinal Cord injury by Game-based Electromyography Biofeedback and EMG Biofeedback
Background and Aims: The purpose of this study was to compare the efficacy and usability of human-computer interface in cervical spinal cord injury with two computer games based and EMG biofeedback. Methods: The sample size was 20 participants (healthy and spinal cervical lesions) who were selected as available. The statistical population of the study was spinal cord injury patients referred t...
[ 3 ] - Estimating average glandular dose in routine mammography screening using neural network
Given the extensive use of common mammography tests for screening and diagnosis of breast cancer, there are concerns over the increased dose absorbed by the patient due to the sensitivity of the breast tissue. Thus, knowing the Mean Glandular Dose (MGD) before radiation to the patient through its estimation can be helpful. For this reason, the MultiLayer Perceptron (MLP) neural network model wa...
