The analytical design of a folded waveguide traveling wave tube and small signal gain analysis using madey's theorem
(EMW Publishing, 2009)
We are developing an analytical model for the design of the folded waveguide traveling wave tube (FWTWT). This analytical model provides the physical view for rapid design optimization of the FWTWT. The design and analysis ...
Effect of treated and untreated filler loading on the mechanical, morphological, and water absorbent properties of water hyacinth fibers-low density polyethylene composites
(Penerbit Universiti Sains Malaysia (USM), 2009)
Cellulose obtained from water hyacinth (Eichhornia crassiper) fibers were blended with low-density polyethylene (LDPE), forming LDPE / water hyacinth fiber WHF) composites. In this work, the effects of filler loading on ...
Contrast enhancement for Ziehl-Neelsen tissue slide images using linear stretching and histogram equalization technique
(IEEE, 2009-12-16)
Ziehl-Neelsen staining method is a common technique used to diagnose tuberculosis infection. Clinical samples such as sputum or tissue are stained using Ziehl- Neelsen procedure and analysed manually by microbiologist for ...
Studies on mechanical alloying of copper-tungsten carbide composite for spot welding electrode
(Springer New York, 2009-12)
This article presents a study on the properties and performance of copper-based composite reinforced with recycled tungsten carbide powder as spot welding electrode. The copper-tungsten carbide composite electrode was ...
The influence of welding parameters and corrosive environment on the joint strength of resistance spot-welded mild steel sheets
(Universiti Malaya, 2009)
In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ...
High sensitivity fiber Bragg grating pressure sensor using thin metal diaphragm
(Institute of Electrical and Elctronics Engineering (IEEE), 2009-12)
A high sensitivity pressure sensor design without a polymer transducer is demonstrated in this paper. The sensor uses a thin metal diaphragm as a pressure transducer instead of a polymer. The sensor is tested to a maximum ...
The influence of welding parameters and corrosive environment on the joint strength of resistance spot-welded mild steel sheets
(University of Malaya, 2009)
In the present work, mild steel sheets consisting two batches were welded by resistance spot welding at different welding parameters and exposed under different environments. The 5% sodium chloride brine was used in the ...
Optical tomography system using digital signal processor: Velocity profile measurement
(Inderscience Enterprises Limited, 2009-06)
The DSP system was customised to control the data acquisition process of 16 x 16 optical sensors array, arranged in parallel beam projection. The data collected was used to reconstruct the cross sectional image of the ...
High degree of testability using full scan chain and ATPG-An industrial perspective
(Asian Network for Scientific Information, 2009)
This study describes an efficient design methodology from an industrial perspective on utilizing Register Transfer Level (RTL) coding style, full scan chain implementation and Automatic Test Pattern Generation (ATPG) to ...
Virtual deformation of soft tissue using bulk variables
(World Scientific and Engineering Academy and Society (WSEAS) Press, 2009)
We present an alternative online simulation model for human tissue. Online simulation of human tissue deformation during surgical training or surgical assistance is becoming increasingly important within the medical ...
