Low-grade waste heat conversion to electricity has drawn much attention toward reduction of production cost (Matsuura, Rowe et al. 1992, Rowe 1995, Ebrahimi, Jones et al. 2014). Organic Rankine cycle has been recently proved as a feasible solution with about 7% thermal efficiency and initial cost of about $2/watt for a high temperature of 116 °C and low temperature of 25 °C (Imran, Park et al. ...

This paper presents a novel optimization technique for energy management studies of an isolated microgrid. The system is supplied by various Distributed Energy Resources (DERs), Diesel Generator (DG), a Wind Turbine Generator (WTG), Photovoltaic (PV) arrays and supported by fuel cell/electrolyzer Hydrogen storage system for short term storage. Multi-objective optimization is used through non-do...

‎we present an application of the dual gabor frames to image‎ ‎processing‎. ‎our algorithm is based on finding some dual gabor‎ ‎frame generators which reconstructs accurately the elements of the‎ ‎underlying hilbert space‎. ‎the advantages of these duals‎ ‎constructed by a polynomial of gabor frame generators are compared‎ ‎with their canonical dual‎.

Quantum-dot Cellular Automata (QCA) is a prominent paradigm that is considered to continue its dominance in thecomputation at deep sub-micron regime in nanotechnology. The QCA realizations of five-input Majority Voter based multilevel parity generator circuits have been introduced in recent years. However, no attention has been paid towards the QCA instantiation of the generic (n-bit) even and ...

Clean air, renewable energy, climate change, safe environments, and the opportunity to live in a healthy community are just few of many issues that fall under umbrella environmental sustainability. The creation bioenergy biomaterials has potential retain energy-environment relationship while simultaneously fostering cleaner, lower-carbon settings. Scientists investigating energy sources like et...

Simple, portable and low-cost experiments as RC RL series circuits are proposed to experiment with DC circuits. Very common elements used: a few electronics components (resistors, capacitors, coils connecting wires) two smartphones. We consider the charging discharging of capacitor in circuit also that coil circuit. Using smartphone an oscilloscope we observe voltages variations which transient...

The effects of CO2 flow rate and calcium source on the particle size (PS) and specific surface area (SSA) of CaCO3 particles were evaluated using microbubble generator (MBG) and air diffuser (AD) systems. The carbonate mineralization (CM) and precipitated calcium carbonate (PCC) methods were employed to produce CaCO3 using gypsum and Ca(OH)2 as the calcium sources, respectively. The CaCO3 parti...

Abstract The issues produced withinside the traditional windmills instigate development of vortex bladeless windmills. Vortex Bladeless is a caused vibrations resonant wind generator. It harnesses strength from phenomenon vorticity referred to as Shedding. Basically, era consists cylinder regular vertically with an elastic rod. oscillates on range, which then generates electricity through trade...

this paper describes the system design of a portable and economical mu rhythm based brain computer interface which employs cypress semiconductors programmable system on chip (psoc). by carrying out essential processing on the psoc, the use of an extra computer is eliminated, resulting in considerable cost savings. microsoft visual studio 2005 and psoc designer 5.01 are employed in developing th...
