The self-powered system is a promising concept for wireless networks due to its independent and sustainable operations without an external power source. To realize this idea, the triboelectric nanogenerator (TENG) was recently invented, which can effectively convert ambient mechanical energy into electricity to power up portable electronics. In this work, a self-powered smart window system was ...
Energy loss straggling of 5.486 MeV alpha particles passing through Melinex, Al, Ni and Cu has been studied as a function of energy loss. The reduction in straggling towards the end of the particle range is predicted by considering the reduction of the stopping power and of the effective charge in the capture and loss of electrons at lower energies. These measurements are compared with theoreti...
Transmission loss and noise reduction of reactive mufflers are determined by linear acoustic theory and unsteady flow field study, respectively. The effects of extending the inlet tube of the muffler, adding holes to the extension, and the number of holes on both transmission loss and noise reduction are investigated. In noise reduction analysis, the Navier-Stokes equations and k-ε model are us...
in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...
The main objective of this Paper was to evaluate the outage cost due to system downtime (Turbine failure) of Egbin Thermal power station from the year 1999 to 2008. The result of the analysis carried out revealed that for the whole ten years under review that there was a power generation loss of 46 percent of the Installed capacity putting the performance of the power station at 54 percent. Fur...
Motion estimation typically consumes 50% to 70% of total power in video encode application. Optimizing the power consumption of motion estimation process is of great importance to low power video applications. Power dissipation increases with computational complexity. Reduction in motion estimation complexity is usually associated with increase in bit rate and a loss of quality. We explore a se...
In this paper, parking lots with bidirectional power flow capability, is used as an achievements of smart power systems. Based on operating conditions, electric vehicles can be considered as a load or generator. For optimal operation of power systems, allocation of these novel units is also necessary same as other distributed generation. In this paper, an optimization problem is proposed for...
