Paraffinic mineral oil lubrication for cold forward extrusion: Effect of lubricant quantity and friction
(Elsevier Ltd., 2013)
In this paper, Finite Element (FE) and experimental analyses have been developed on the deformation of aluminium billet over a tool. Effect of friction resulted from the use of additive-free ISO460-compliant paraffinic ...
Conjugate heat transfer in porous annulus
(Begell House, Inc., 2014)
The effect of conductivity ratio on temperature at a solid-porous interface is one of the most important aspects in conjugate heat transfer. The present work is undertaken to investigate heat transfer behavior in a porous ...
Design of an infrared tomography system for detection of bubbles
(Penerbit UTM Press, Universiti Teknologi Malaysia., 2011-08)
In this study, an optical process tomography with 2 orthogonal projections is being designed to be implemented at a vertical column modelled. The tomography system will be designed from the development of transducer pairs ...
Detection of human stress using short-term ECG and HRV signals
(World Scientific Publishing Company, 2013-04)
This paper introduces a method for resolving the problem of human stress detection through short-term (less than 5 min) electrocardiogram (ECG) and heart rate variability (HRV) signals. The explored methodology helps to ...
Study of the effect of brightness after penetration of light from a lens
(Penerbit UTM Press, 2013)
There are many types of component that are able to produce light and the light is produced based on the angle and wavelength of the lens. Light penetration depends on the type of material used. The tests are done using ...
Surface electromyography for assessing triceps brachii muscle activities: A literature review
(Elsevier B.V., 2013)
The goal of this review was to summarise the scientific findings of research conducted on the triceps brachii muscle using surface electromyography. To achieve this goal, we searched through several articles available from ...
Multiple physiological signal-based human stress identification using non-linear classifiers
(2013)
This paper describes the human stress identification using multiple physiological signals. The Electrocardiogram (ECG), Electromyogram (EMG), Heart Rate Variability (HRV), Galvanic Skin Response (GSR), and Skin Temperature ...
Design and development of an automated, portable and handheld tablet personal computer-based data acquisition system for monitoring electromyography signals during rehabilitation
(Institution of Mechanical Engineers (IMechE), 2013-03)
This article describes the design of a robust, inexpensive, easy-to-use, small, and portable online electromyography acquisition system for monitoring electromyography signals during rehabilitation. This single-channel ...
Coherence in muscle activity of the biceps brachii at middle, proximal and distal tendon region among the arm wrestling contestants
(Scientific Publishers of India, 2013)
The aim of this study was to analyze the electromyographic (EMG) activity of biceps brachii (BB) muscle under the same muscle contraction in three different locations. For this reason, arm wrestling contest was conducted ...
Hardware developments of an ultrasonic tomography measurement system
(International Frequency Sensors Association (IFSA), 2011-01)
This research provides new technique in ultrasonic tomography by using ultrasonic transceivers instead of using separate transmitter-receiver pair. The numbers of sensors or transducers used to acquire data plays an important ...
