Optimizing activation and deactivation of base station transmissions provides an instrument for improving energy efficiency in cellular networks. In this paper, we study the problem of performing cell clustering and setting the activation time of each cluster, with the objective of minimizing the sum energy, subject to a time constraint of serving the users' traffic demand. Our optimization framework...
This paper is an introduction to software performance automated testing and theory. It introduces the features of Open Xml storage and SQL Server storage. Then this paper sets three state scenes and chooses different test automated tools respectively. Finally, it uses tools to monitor software performance index from these two data storage systems. Results are then analyzed, comparing the quality performance...
Based on ergonomics, fuzzy theory and BP neural network, weighted integrated comfort index WICI is proposed in the paper. WICI is calculated as the weighted sum of integrated comfort indices which gained by the data recorded in different periods of wheelchair assessment experiments. The integrated comfort index ICI is the output of a trained BP neural network. The inputs of the network are the main...
In Shared-Savings EMC projects, EMCo bears almost all the risks, including those of external environment, energy-saving technology, marketing, organization and management, and customer. Therefore, Risk prevention and risk management is especially important for EMCo. This article analyzes the features of Shared-Savings EMC's risks, apply subjective grading method to make a qualitative analysis, and...
Ramie fiber and high density polyethylene (HDPE) were used as raw materials, ramie fiber/HDPE composites were prepared by compression molding process, tetrakis[methylene(3,5-di-tert-butyl-4-hydroxyhydrocinnamate)] methane(1010A) was used as anti-oxidant, the thermo-oxidative aging test was carried out and the variations in properties of different composites during aging were studied. The results show...
The capital asset pricing model (CAPM) can not be applied to estimate the capital cost of the project because of lack of applying condition due to the inefficiency of the market. In this paper we analyze the behavioral capital asset pricing model(BAPM) which has been only used in the financial markets and we get the conclusion that it can be used to estimate the project capital cost. We also modify...
