Nowadays, mail services are used rigorously for communication purpose. Due to the widespread demand for mail services, performance degradation may occur for mail servers. Performance is an open issue that is affected by many factors including the technical factors. To identify the factors that have an impact on the performance of the mail services, we have carried out an experimental study by f...
In this paper, we develop a green handover protocol in two-tier OFDMA macrocell-femtocell networks. To improve the energy efficiency of femtocell base station, the proposed green handover protocol can intelligently switch on its radio communication and associated processing, or called as “wake up” from the idle mode, if the remainder data of a mobile host can be completely uploaded through the ...
In this paper a model for the performance prediction and optimization of air coolers for indirect refrigeration systems is presented. The model applies for finned rube air coolers operating under frosting conditions and considers the transient heat and mass transfer between humid air and air cooler surfaces. The model is extended with an energy consumption analysis for the compression refrigera...
The data fusion technique has been investigated by many researchers and has been used in implementing several information retrieval systems. However, the results from data fusion vary in different situations. To find out under which condition data fusion may lead to performance improvement is an important issue. In this paper, we present an analysis of the behaviour of several well-known method...
Monitoring on smartphones and mobile devices presents several challenges, such as limited battery power and computing resources, but also provides some unique opportunities, particularly the ability to capture contextual data. Incorporating the context of the activities being monitored could improve performance modeling. Real-time monitoring could also be used to facilitate contextaware applica...
A large number of commercial simulation tools support performance oriented studies of complex computer and communication systems. Reliability of these systems, when desired, must be obtained by remodeling the system in a different tool. This has obvious drawbacks: (i) substantial extra effort is required to create the reliability model, (ii) through modeling error the reliability model may not ...
This paper discusses an application of neural network system on the performance prediction of solid boronizing. To build the mathematics model between the solid boronizing and the prediction of boronizing performance, a neural network approach is adopted. This approach overcomes a lot of problems in the traditional approaches and provides a stable and effective approach.
