Human emotions classification and EEG channel reduction: A review
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)Brain signals are collected from the human scalp through a set of electrodes placed over the entire scalp. In recent years, the researchers are using higher number of Electroencephalography (EEG) channels to collect the ... -
An improved defect classification algorithm for six printing defects and its implementation on real printed circuit board images
(ICIC International, 2012-05)Because decisions made by human inspectors often involve subjective judg- ment, in addition to being intensive and therefore costly, an automated approach for printed circuit board (PCB) inspection is preferred to eliminate ... -
In vitro evaluation of finger's hemodynamics for vein graft surveillance using electrical bio-impedance method
(American-Eurasian Network for Scientific Information (AENSI), 2014-03)Electrical bio-impedance measurement has great potential in many biomedical applications including vein graft surveillance. Studies have shown that thrombosis was the major cause of the vein graft failure. The meticulous ... -
Infant cry classification to identify asphyxia using time-frequency analysis and radial basis neural networks
(Elsevier Ltd, 2012-08)A cry is the first verbal communication of infants and it is described as a loud, high-pitched sound made by infants in response to certain situations. Infant cry signals can be used to identify physical or psychological ... -
Measurement of the flexible bending force of the index and middle fingers for virtual interaction
(Elsevier Ltd., 2012)In this paper the development of a new low cost dataglove based on fingertip bending tracking techniques for measuring the fingers bending on various virtual interaction activities is presented as an alternative to the ... -
Mobile robot navigation by using fuzzy information of moving two-wheeled motion features
(IJENS Publishers, 2013)The purpose of indoor and outdoor mobile robot navigation is to move the mobile robot toward target with stable target navigation. In this study, motion information from the movements of the two-wheeled mobile robot is ... -
Mobile robot stable-target navigation control via encoder data feedback
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)This experiment and research work is very important as for the first-step in a research of mobile robot which is equipped with encoders. It is very important to ensure that the encoder is able to read the counter and give ... -
NMPC-PID based control structure design for avoiding uncertainties in attitude and altitude tracking control of quad-rotor (UAV)
(IEEE Conference Publications, 2014-03)The extensive consideration in this research article is to utilize the advantages of two most popular control techniques which are Non-Linear Model Predictive Control (NMPC) and Proportional Integral and Derivative (PID) ... -
Performance comparison of daubechies wavelet family in Infant cry classification
(IEEE Conference Publications, 2012)Infant cry is a non-stationary, loud, high-pitched signal made by infants in response to certain situations. This acoustic signal can be used to identify physical or psychology status of infant. The aim of this work is to ... -
Physiological signals based human emotion recognition: A review
(Institute of Electrical and Electronics Engineers (IEEE), 2011-03-04)Recent research in the field of Human Computer Interaction aims at recognizing the user's emotional state in order to provide a smooth interface between humans and computers. This would make life easier and can be used in ... -
PID based controller design for attitude stabilization of Quad-rotor
(American-Eurasian Network for Scientific Information (AENSI), 2014)This article presents a PID based control approach for stabilizing the attitude of quad-rotor UAV during flying. To solve the stability problem of quad-rotor UAV, some suitable and easy feedback control algorithm can be ... -
Principle component analysis for the classification of fingers movement data using dataglove "glovemap"
(International Association for Engineeering and Management Education, 2013-03)Nowadays, many classifier methods have been used to classify or categorizehuman body motions of human posture including the classification of fingers movement. Principal Component Analysis (PCA) is one of classical method ... -
