The increasing programmability and parallelism of commodity graphics processing units (GPUs) makes them strong candidates for addressing some of the computational challenges faced by the remote sensing community. We have addressed one of those problems: the implementation of a fully automatic system for registration of remote sensing images. Our previous research in this field has focused on fe...

Abstract Exact assessment of self-heating is great importance to the thermal management electronic devices, especially when completely considering cross-scale heat conduction process. The existing simulation methods are either based on convectional Fourier's law or limited small system sizes, making it difficult deal with noncontinuum transport efficiently. In this paper, a hybrid phonon Monte ...

The positioning systems' high accuracy and reliability are crucial enablers for various future applications, including autonomous shipping worldwide. It is especially challenging the Arctic region due to lower number of visible satellites, severe ionospheric disturbances, scintillation effects, higher delays than in non-Arctic non-Antarctic regions. In regions up North, conventional satellite s...

Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...

This work proposes a real-time deep learning-based model for predicting the small-signal stability of an electrical network. The trained models equip power system operators with accurate and fast monitoring tool which can be used during online operation. To achieve this objective, three different architectures are employed in research; stacked long short-term memory (LSTM), convolutional neural...

Microchannel heat sinks are an efficient cooling method for semiconductor packages. However, to properly cool increasingly complex and thermally dense circuits, microchannel designs should be improved expanded on. In this paper, with secondary channels ribs investigated using computational fluid dynamics coupled a multi-objective optimization algorithm determine propose optimal solutions based ...

An unsteady mixed convectional boundary layer flow of a Casson nanofluid having magnetic ( Fe 3 O 4 ) and non-magnetic Al 2 nanoparticles suspension within two different types base fluids, water (Newtonian) sodium alginate (non-Newtonian), which incorporates viscous dissipation effects over nonlinear stretching sheet with field effects. Some suitable non-dimensional similarity transformations a...

Nano-sized BaTiO3 powders with particular Nb concentrations were prepared by Rotary- Hydrothermal (RH) method. Hydrothermal method was used at 180 °C for 5 hours with new Ti pressure and the teflon vessel was rotated at a speed of 160 rpm during the hydrothermal reaction. New hydrothermal method was used instead of previous solid state reaction for the system BaTiO3±Nb<sub...

We have previously demonstrated that prophylactic intake of dexamethasone improves maximal oxygen uptake (Vo(2)max) in high altitude pulmonary edema (HAPE) susceptible subjects 4 to 6 h after a 2-day climb to 4559 m. However, since with this ascent protocol HAPE usually develops after the first night at 4559 m or later, we hypothesized that a continued dexamethasone prophylaxis would result in ...
