Hardware developments of an ultrasonic tomography measurement system
(International Frequency Sensor 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 ...
Asynchronous brain machine interface-based control of a wheelchair
(Springerlink, 2011)
A brain machine interface (BMI) design for controlling the navigation of a power wheelchair is proposed. Real-time experiments with four able bodied subjects are carried out using the BMI-controlled wheelchair. The BMI is ...
J-integral evaluation in two dimensional interacting cracks
(Trans Tech Publications, 2011)
This paper investigates crack interaction of multiple edge cracks in elastic solid finite body under pure Mode I loading. The cracks are located in parallel to another in 2D plate model. The stress intensity factors (SIFs) ...
FPGA implementation for GMM-based speaker identification
(Hindawi Publishing Corporation, 2011)
In today's society, highly accurate personal identification systems are required. Passwords or pin numbers can be forgotten or forged and are no longer considered to offer a high level of security. The use of biological ...
Photoinduced absorption and nonlinear optics of triglycine selenate single crystals under uniaxial pressure
(Elsevier B.V., 2011-06-15)
We studied an influence of uniaxial pressure on the triglycine selenate single crystals during simultaneous illumination by the continuous wave 532 laser at power about 300 mW. Simultaneously we have studied two-photon ...
Combination of Hargreaves method and linear regression as a new method to estimate solar radiation in Perlis, Northern Malaysia
(Elsevier Ltd., 2011-11)
The best way to obtain the solar radiation data of a particular place of interest (POI) is to measure at the specific site continuously and accurately over the long term. However, due to financial, maintenance, calibration ...
Stiffness properties of porous silicon nanowires fabricated by electrochemical and laser-induced etching
(Elsevier Ltd., 2011-08)
Nanowires with dimensions of few nanometers were formed on the whole etched surface. The optical analysis of silicon nanostructures was studied. Blue shift luminescence was observed at 660 nm for PS produced by electrochemical ...
Design aspects of bioreactors for solid-state fermentation: A review
(Croatian Association of Chemical Engineers, 2011)
Solid-state fermentation has gained renewed attention, not only from researchers but also from industries, due to several advantages over submerged fermentations. This is partly because solid-state fermentation has lower ...
Characterization of Co-Cr-Mo (F-75) alloy produced by solid state sintering
(Trans Tech Publications, Switzerland, 2011)
This research was carried out to fabricate and characterize Co-Cr-Mo (F-75) alloy. The samples have been prepared via solid state sintering. The lab work comprises the mixing of F-75 alloy powder with 2 wt. % of binder. ...
Effect of increasing tellurium content on the electronic and optical properties of cadmium selenide telluride alloys CdSe1-xTe x: An ab initio study
(Elsevier B.V., 2011-06-16)
An all electron full potential linearized augmented plane wave method, within a framework of GGA (EV-GGA) approach, has been used for an ab initio theoretical study of the effect of increasing tellurium content on the band ...
