In this paper, processor scheduling policies that “save” processors are introduced and studied. In a multiprogrammed parallel system, a “processor saving” scheduling policy purposefully keeps some of the available processors idle in the presence of work to be done. The conditions under which processor saving policies can be more effective than their greedy counterparts, i.e., policies that neve...
The objective of this paper is to develop and evaluate an Energy COnservation PET (ECOPET) system in a PDA platform with mobile learning strategy for energy education. The system helps learners learn appropriate energy consumption by making a better trade-off decision while facing the dilemma between a virtual pet’s comfortable living and saving more energy. The system allows learners to play a...

The energy saving and emission reduction in thermal plant is complex, with the open, non-equilibrium and interoperability features. In order to identifying the order parameters affecting plant system, a co-evolution model of energy saving and emission reduction in thermal power plant was built based on synergetic theory. According to the feathers of potential function based on mutation theory, ...
For purpose of saving cost the generation of wireless mobile communicat ion evolved into LTE system by using MIMO-OFDM technology. But for the higher data rate it expenses higher energy. So, an efficient antenna management system is needed to be designed to save energy per bit transmission. In MIMO there are mult iple RF channels for transmitting data which consumes much energy. In the case of ...
Electro-hydraulic proportional control valves are widely applied for motion control in the electro-hydraulic fluid power system. Normally, a sliding spool is used in the proportional control valve to control the flow direction and flow rate passing through the valve, as a result, the meterin and meter-out orifices are mechanically connected [1]. The sliding spool makes the system robust and eas...
In the IEEE 802.16e system, we propose an efficient power saving mechanism that increases the unavailability interval when the mobile station (MS) uses multiple power saving classes(PSCs). Through the simulation results, we show that the proposed mechanism reduces the power consumption of MSs considerably compared with conventional mechanism.
Steady growth in the telecommunication industry providing data, voice and video is very likely to continue in the foreseeable future. This growth is supported by expansion into the new markets, especially in Asia, accelerated widespread of wireless and broadband technology, and strong demand for more efficient, power saving solutions. As the result of the growth, the telecommunication infrastru...
This paper investigates the power saving mechanism of Universal Mobile Telecommunications System (UMTS). UMTS discontinuous reception (DRX) is exercised between the network and a mobile station (MS) to save the power of the MS. The DRX mechanism is controlled by two parameters: the inactivity timer threshold tI and the DRX cycle tD . Analytic analysis and simulation model are proposed to study ...
