Solar radiation exergy and quality performance for Iraq and Turkey
(Inderscience Enterprises Ltd., 2018)
The present study is conducted with two primary objectives: First, a new formulation for the maximum efficiency of the solar radiation conversion is developed by considering the radiative energy transfer between two surfaces ...
Characterization of chemically modified thin films for optimization of metal CMP applications?
(Cambridge University Press, 2013)
Metal CMP applications necessitate the formation of a protective oxide film in the presence of surface active agents, oxidizers, pH regulators and other chemicals to achieve global planarization. Formation and mechanical ...
Biomaterials applications of chemical mechanical polishing
(IEEE, 2012)
Chemical Mechanical Polishing (CMP) is used in semiconductor industry to enable planarization of the interlayer dielectrics and metals. In this study, CMP is used as a polishing technique to modify the surface roughness ...
Topology optimization of constrained and unconstrained damping layers
(Canadian Acoustical Association, 2019)
Damping is an effective way of suppressing mechanical vibrations. Passive constrained and unconstrained layer damping patches are often used in the industry as damping solution for vibrations and acoustics problems. In ...
Cyclic deformation response of ultra-fine grained titanium at elevated temperatures
(Elsevier, 2019-05)
This study focuses on the high-temperature cyclic deformation response (CDR) of ultra-fine grained (UFG) titanium of commercial purity (grade 4) processed via equal channel angular extrusion as a severe plastic deformation ...
Heart motion prediction based on adaptive estimation algorithms for robotic assisted beating heart surgery
(IEEE, 2013)
Robotic-assisted beating heart surgery aims to allow surgeons to operate on a beating heart without stabilizers as if the heart is stationary. The robot actively cancels heart motion by closely following a point of interest ...
Chemical mechanical planarization studies on gallium nitride for improved performance
(IEEE, 2015)
In this study, a systematic experimental approach has been followed to determine the conditions to promote material removal rate while controlling surface defectivity for GaN CMP. Silica based slurries were used to optimize ...
Chemical mechanical polishing implementation on dental implants
(IEEE, 2015)
In this study, chemical mechanical polishing (CMP) technique is introduced as a new alternative to generate controlled nano/micro scale roughness on the titanium implant surfaces. It is known that micro scale patterns ...
Effect of grain size on the very high cycle fatigue behavior and notch sensitivity of titanium
(Elsevier, 2019-12)
The very high-cycle fatigue performances of coarse-grained and ultrafine-grained titanium samples with different geometries at ambient temperature and various stress amplitudes were investigated. Severe plastic deformation ...
Analysis of perlite and pumice based building insulation materials
(Elsevier, 2016-06)
Insulation panels composed of perlite, pumice, and cement were fabricated. Perlite and pumice were used to achieve high thermal resistance, and low density. Experimentation was conducted for determining
R-values of ...
