In cellular wireless CDMA systems, it is required that the base station receives constant power signals from mobile users, in order to guarantee link quality. This is achieved by properly adjusting the uplink transmitted power of each mobile. Usually, the base station is responsible for informing each individual mobile of the power adjustment. However, when the radio channel varies drastically ...
In this paper, the resonance optical absorption method, is used to measure the Cu atoms number density in different power levels of power supply. Atoms are sputtered from a Cu target during plasma magnetron sputtering deposition. For the light source, a commercial Cu hollow cathode lamp is used. For measurement of gas temperature, a small percentage of N2 is added to the gas mixture and the gas...
Natural gas is transmitted at high pressure levels. For industrial and domestic consumptions, this pressure should be reduced. Usually, mechanical valves accomplish this process. Turbo-expanders can replace these equipments and reduce gas pressure at city gate gas pressure reduction stations as well. Besides, they can recover the huge amount of high pressure gas energy and drive electrical gene...
To assure safe shutdown of a nuclear power plant, there must always be reliable means of decay heat removal provided, in last resort, by an Emergency Core Cooling System (ECCS). Currently the majority of nuclear power plants in the US utilize diesel generator sets as on-site emergency power generating units. In addition to the loss of off-site power, plants can lose their on-site AC power, a co...
Humans are an integral part of power plants, ranging from construction to routine maintenance. Analysis of the presence and performance of the human factor can play an effective role in reducing and/or optimizing the use of energy resources. Therefore, in this research the investigation of the plant operator's presence direction in order to control a type of accident with the implementation of ...
This paper investigates the influence of voltage dips on large electric driven gas compressors (EDC) considering a typical application in the oil and gas industry. Voltage or power dips are electric disturbances encountered in EDC which are mainly caused by faults in the electrical grid and might last for durations up to 150ms. For gas compression applications, the loss of driver torque often p...
In this paper, three-dimensional ultrasonic anemometer and multi-channel have been used to monitor the flow field of a subway station in Beijing. Based on releasing sulfur hexafluoride (SF6) hall, gas transmission diffusion range studied. The results show that under natural ventilation, would be controlled by regular mainstream field. Because obvious subsidence heavy tends accumulate ground. ai...
By increasing the extraction of natural gas, its role in the restructured power systems is being expanded, due to its lower pollution. Iran has the second largest reserves of natural gas in the world and exports it to different countries. This paper represents long run analysis of natural gas export from Iran to Turkey as a case study, considering direct transfer and exporting via the power mar...
