Modeling of solar thermal selective surfaces and thermoelectric generators
A thermoelectric generator is a solid-state device that converts a heat flux into electrical power via the Seebeck effect. When a thermoelectric generator is inserted between a solar-absorbing surface and a heat sink, a solar thermoelectric generator is created which converts sunlight into …

Analysis of Garbage Collector Algorithms in Non-Volatile Memory Devices
Non-volatile memory devices or flash, even with many advantages, still have a few problems such as the inability to update data in place. This necessitates the need for a garbage collector (GC) that can collect active data and create space by erasing flash blocks. However this is a very costly …

Silicon-based pH sensor for biological and environmental applications
… pH sensing is confined to 6 to 8. The fabricated device used n-type silicon, so only five acidic solutions between pH 5 and pH 7 were tested. Device test results proved to be somewhat problematic. We were not able to obtain consistent capacitance measurements for a particular pH solution. For some …
