Effective power saving mechanism is the most significant issue for extending the lifetime of mobile stations in wireless metropolitan area network (MAN). In this paper, we propose an effective method to analyze the system performance of the power saving class type II in IEEE 802.16e. We present a queueing model with two kinds of vacation mechanisms to capture the working principle of the networ...

pond aquaculture is the most significant fish production method in central europe, approximately 70% of the total fish production is originated from traditional fish ponds in this region, which is a resource-saving, ecologically sustainable production method. however, the growth of this sector is not expected because of the low production capacity of valuable fish species and the relatively hig...

We present a power-saving method for large-scale distributed storage systems of Internet hosting services, whose prime example is a video/photo sharing service. The idea behind our method is to periodically exchange stored data among disks in an autonomous way so as to skew the workload towards a small number of disks while not overloading them. The objective of this paper is to explore a power...

This paper presents electricity utilization and saving potential assessment for residential lighting demand side management program. The assessment involves combined Baseline Energy Use method and Analytic Hierarchy Process which represent technical and customer preference approaches, respectively. Residential lighting load curve and lamps’ share of ownership are estimated based on the first me...

As energy has become one of the key operating costs in running a data center and power waste commonly exists, it is essential to reduce energy inefficiency inside data centers. In this paper, we develop an innovative framework, called PowerTracer, for diagnosing energy inefficiency and saving power. Inside the framework, we first present a resource tracing method based on request tracing in mul...

—Mobile ad hoc networks (MANETs) can be configured by mobile terminals without any network infrastructure such as Access Points (APs), and they are expected to be a useful tool during serious disasters such as a large earthquake. Many studies have concentrated on clustering methods that aim at power saving and loadbalancing in MANETs. For the clustering mechanism of a MANET, we have proposed a...

A method for activating ISE is proposed that can allow determination of the fluoride concentration at ng mL(-1) level with good precision and accuracy. Fluoride ISE is activated in 0.5 mol L(-1) HClO4 medium and then fluoride is determined in the same medium. The linear range for the determination of fluoride is between 1.00 x 10(-2)-1.00 x 10(-7) mol L(-1), and the detection limit of the metho...
