energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...
One of the important issue in MANETs is energy saving. Recent studies show that Network coding can reduces energy consumption by less transmission in MANETs. Encryption/decryption, transmission cost and transmission time are worked as source of energy consumption in MANETs. Network coding provides intrinsic security based on which encryption can be done quite efficiently, but to provide securit...
The total power consumption of all semiconductor plants exceeds 100 million kWh per year, with about 43% of this consumption to operate air conditioning facilities. This high power consumption is due to the requirement of the cleanliness kept for clean rooms, with extremely high power consumed to the air transferring power. Oki developed the fan module unit (FMU) type air conditioning system to...
THE EFFECT OF TRAFFIC MANAGEMENT ON VMS SIGN AND PILOT SIMULATION OF AZADI STREET TO ENGHELAB SQUARE
Today’s, a common problem in cities is increasing delay and reducing the speed of traffic. On the other wise increasing costs of acquisition in urban area are not allow new routes and highways. Also construction of new highway or street such as Imam Ali highway and Sadr highway in Tehran lead to develop new applications (such as BRT lane ,…) And become quickly saturate and less eff...
One of the most important energy-saving of building is suitable choice of insulation with regard to the climatic conditions of each region. In this study, the effects of building insulations approved by the Research Center of Way, Housing and Urban Development with regard to the cost of insulation on energy consumption in the region of Yazd, Tehran and Tabriz was evaluated by software Energy Pl...
Power consumption of modern datacenters is increasing rapidly. Databases, especially OLTPs, have become a major application at datacenters. Therefore, power-saving management for OLTP applications has become an important task for user budgets and datacenter operations. A recent report described that disk drives consume about 70% of total power of IT equipment when such large OLTP applications a...
Many energy-aware routing protocols have been proposed for wireless sensor networks. Most of them are only energy savers and do not take care about energy balancing. The energy saver protocols try to decrease the energy consumption of the network as a whole; however the energy manager protocols balance the energy consumption in the network to avoid network partitioning. This means that energy s...
The authors propose a solar cooling system employing a steam-driven triple effect absorption chiller as a new technique for saving CO2 emission in the air conditioning field. The absorption chiller is a cooling machine using thermal energy as a drive source, and it is ideal for utilizing solar heat. In addition, by employing a triple effect absorption chiller of high efficiency, a high energy s...
During recent years, attention in ‘Green Computing’ has moved research into energy-saving techniques for home computers to enterprise systems' Client and Server machines. Saving energy or reduction of carbon footprints is one of the aspects of Green Computing. The research in the direction of Green Computing is more than just saving energy and reducing carbon foot prints. This study provides a ...
