5mm × 5mm sized slug on high power LED stress and junction temperature analysis
(Trans Tech Publications (TTP), 2013)
Conventional incandescent lamps are being replaced by high power light emitting diode as a lighting source due to it ascendancy in terms of physical size, performance, output and lifetime. Nevertheless, the reliability and ...
Objective evaluation of speech dysfluencies using wavelet packet transform with sample entropy
(Elsevier Inc, 2013-05)
Dysfluency and stuttering are a break or interruption of normal speech such as repetition, prolongation, interjection of syllables, sounds, words or phrases and involuntary silent pauses or blocks in communication. Stuttering ...
Shear speed analysis on Sn-3.9Ag-0.6Cu Solder
(Trans Tech Publications (TTP), 2013)
Ball Grid Array (BGA) is a type of semiconductor interconnection used in Integrated Circuit (IC) which is being scaled down to micro and nano size. The reliability of BGA in IC becomes a concern as the size of IC reduces. ...
Low density fibrous material surface light reflectance analysis
(AENSI Publisher All rights reserved, 2013-10)
The light based surface finishing of most product measurement is an important feature in the industries. In this paper, a lab fabricated tester for investigation on the quality of low density paper which was represent by ...
Improved subtraction function for logarithmic number system
(Elsevier Ltd., 2013)
Logarithmic number system can be highly considered as an alternative to floating-point, specifically for applications that require a wide dynamic range of numbers for their arithmetic operations. To date, its implementation ...
FSS microchannel fluid flow profile investigation at high and low Re number
(AENSI Publisher All rights reserved, 2013-10)
The fundamental understanding of dynamic fluid flow behavior in different geometry channel is crucial due to transport phenomena influence on the key design and process control of the microfluidic systems. Recently, the ...
Microfluidic channel depth determination with Tywman-Green interferometer
(Springer-Verlag London., 2013-07)
A microfluidic channel is fabricated on a silica wafer using reactive ion etching (RIE). The depth of the microfluidic channel has been measured using a surface profilometer and a Twyman-Green interferometer (TGI) setup. ...
The SEM & AFM images of MEH-PPV films below CLA region
(Elsevier Ltd., 2013)
Poly [2-methoxy-5--ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) is an example of conducting polymer that used to fabricate an organic light emitting diode (OLED). The surface roughness and homogeneity of MEH-PPV film ...
Terahertz detection using nanorectifiers
(Institute of Electrical and Electronics Engineers (IEEE), 2013-12)
We report on the low-temperature detection of free-space radiation at 1.5 THz using a unipolar nanodiode, known as the self-switching diode (SSD), coupled with a spiral microantenna. The SSD, based on an asymmetric ...
Finite element analysis of thermal distributions of solder ball in flip chip ball grid array using ABAQUS
(Emerald Group Publishing Limited, 2013)
Purpose - The increased use recently of area-array technology in electronic packaging has similarly increased the importance of predicting the thermal distribution of area-array solder interconnection. As the interconnection ...
