Ga2O3 is being actively explored for high-power and high-temperature electronics, deep-ultraviolet optoelectronics, other applications. Efficient n-type doping of has been achieved, but p-type faces fundamental obstacles due to compensation, deep acceptor levels, the polaron transport mechanism free holes. However, aside from achieving conductivity, plenty opportunity exists engineer position F...

in this study, the effect of cold rolling process on the microstructure and texture evolution in 1wt. % si non-orientedelectrical steel was investigated. for this purpose, all samples were processed through single-stage hot rolling at1100 ° c and two-stage cold rolling (cross rolling and unidirectional rolling) with intermediate annealing at 650 °cfor 35 seconds. finally, all of them were fully...

Chromium oxide (α-Cr2O3) thin films were prepared using thermal annealing of chromium (Cr)films deposited on quartz substrates by direct current (DC) magnetron sputtering. The annealingprocess of the films was performed for different times of 60, 120,180 and 240 min. The influenceof annealing time on structural, morphological and optical properties of the prepared films wasinvestigated by diffe...

Quantum annealing (QA) has been proposed as a quantum enhanced optimization heuristic exploiting tunneling. Here, we demonstrate how finite range tunneling can provide considerable computational advantage. For a crafted problem designed to have tall and narrow energy barriers separating local minima, the D-Wave 2X quantum annealer achieves significant runtime advantages relative to Simulated An...

The effects of sample storage, target preparation and annealing temperature on a nested polymerase chain reaction (PCR) test for Toxoplasma gondii DNA were investigated with experimentally seeded amniotic fluids to simulate congenital infection. Aliquots of 17 amniotic fluid samples remaining after investigation for conditions other than toxoplasmosis and seeded to contain small numbers of T. g...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

Placement of multiple dies on an MCM substrate is a difficult combinatorial task in which multiple criteria need to be considered simultaneously to obtain a true multi-objective optimization. Our design methodologies consider multi-objective component placement based on thermal reliability, routing length and chip area criteria for multi-chip module. The purpose of the multi-objective optimizat...

Ant Colony Optimization (ACO) exhibits parallelism, contains certain redundancy and historical information of the past solutions with pheromone trail, and is suitable for implementation on massively parallel architecture. But it is not easy to avoid local optima, especially for large-scale schedule problems. Simulated annealing (SA) is a naturally serial algorithm, but its behavior can be contr...

There is a renewed interest in photovoltaic solar thermal (PVT) hybrid systems, which harvest solar energy for heat and electricity. Typically, a main focus of a PVT system is to cool the photovoltaic (PV) cells to improve the electrical performance, however, this causes the thermal component to under-perform compared to a solar thermal collector. The low temperature coefficients of amorphous s...
