An experimental and computational investigation of a thin piezofan cooler
(IEEE, 2017)
Recent trends in electronic cooling systems are targeted towards a reduction in size, therefore small form factor/miniature cooling devices are of interest to various applications. Among these devices are piezoelectric ...
Acoustic analysis of an axial fan
(IEEE, 2017)
Axial fans are often used in cooling electronic enclosures where low noise levels are highly demanded. Therefore, methods for predicting the noise emitted by an application including single or multiple fans are desirable ...
Application of a novel friction stir spot welding process on dissimilar aluminum joints
(Elsevier, 2018-10)
Intermediate layer friction stir spot welding (IL-FSSW) is introduced in this study as a novel spot welding technique to eliminate the keyhole associated with the conventional friction stir spot welding (FSSW). This process ...
Impact of junction temperature over forward voltage drop for red, blue and green high power light emitting diode chips
(IEEE, 2017)
Commercially available light emitting diodes (LEDs) that have high efficiencies and long lifetime are offered in advanced packaging technologies. Many cooling systems were developed for current LED systems that enable a ...
A comparative study for the junction temperature of green light-emitting diodes
(IEEE, 2019-10)
Solid-state lighting devices offer a wide variety of color options applicable for general and automotive lighting, various display systems, and a number of niche applications. As they get smaller, generated heat fluxes ...
Sound performance investigation of composite materials for the soundbox of a membrane musical instrument
(International Institute of Acoustics and Vibrations, 2015)
The materials used in the manufacture of musical instruments with wooden sound box is obtained from trees in general. This fact creates difficulties due to problems with limited environmental resources. In addition, such ...
Surface characterization driven CMP optimization for gallium nitride
(ECS, 2016)
Gallium nitride is a hard and chemically inert material demoting high material removal rates in the chemical mechanical planarization (CMP) applications. This paper focuses on the optimization of the process conditions to ...
Workability characteristics and mechanical behavior modeling of severely deformed pure titanium at high temperatures
(Elsevier, 2014-01)
In the present study, compression tests were performed at temperatures of 600–900 °C and at strain rates of 0.001–0.1 s−1 to study the deformation and workability characteristics of commercially pure titanium after severe ...
Elevated temperature mechanical behavior of severely deformed titanium
(Springer Nature, 2014-05)
In this investigation, compression tests were performed at a strain rate of 0.001-0.1 s(-1) in the range of 600-900 degrees C to study the high temperature deformation behavior and flow stress model of commercial purity ...
Discrete-dipole approximation with surface interaction: computational toolbox for MATLAB
(Elsevier, 2011-07)
We describe a MATLAB toolbox that utilizes the discrete-dipole approximation (DDA) method for modelling light interaction with arbitrarily-shape scatterers in free space as well with planar surface interaction (DDA-SI). ...
