CCTV-based video monitoring technology is one of the fastest growing security technologies markets. The existing systems are, however, still not in a position to be used prevent crime. For public safety purposes, large networks cameras are increasingly deployed places like Residential Buildings, College Campus, offices, airports, railway stations, and shopping malls. Such primarily dependent on...

The power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. This paper presents modeling and optimization of a photovoltaic (PV)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in Rafsanjan, Iran. For this location, different hybrid systems are studied and ...

ôbjective: depression among elderly in ïran has not been well studied. little is known about the true rates of depression, it correlates or how well it is treated. this research is part of a series examining health status of older people using the geriatric depression scale-15 (gds-15). methods: ône thousand and nine hundred seventy five (1975) older people living in razavi khorasan province we...

This paper deals with the optimal design of a stand-alone hybrid system composed of wind turbines, solar photovoltaic panels and batteries. To compensate for a possible lack of energy from these sources, an auxiliary fuel generator guarantees to meet the demand in every case but its use induces important costs. We have chosen a two-stage robust approach to take account of the stochastic behavio...

Small-scale hybrid stand-alone power systems are becoming popular alternatives in remote and island areas where grid connection is not economically or technically viable. Harnessing the abundant supply of wind and solar energy can play an important role in ensuring an environmentally friendly and clean energy generation for remote and isolated communities. However, renewable energy sources are ...
