In order to improve transmission throughput of a multi-hop wireless network, many efforts have been made in recent years to reduce traffic and hence transmission collisions by constructing backbone networks with minimum size. However, many other important issues need to be considered. Instead of simply minimizing the number of backbone nodes or supporting some isolated network features, in this work,...
A good information system (IS) makes it possible to improve organizational efficiency and effectiveness, which can provide competitive advantage. Now the most of company through the purchase of existing information systems to complete the construction of enterprise information, it can save a lot of money. So the information system evaluation is an important task to the company. In this paper, an information...
Using Delphi method to determine the indicators and their weights of performance evaluation of enterprise's marketing team members, this paper proposes a performance evaluation model of enterprise's marketing team members based on BP neural network. Then, it operates the empirical analysis in an enterprise. The empirical results show that the model is an effective evaluation method because its output...
This paper mainly contributes to the estimation of 2-D current-density distribution in a moving arc root. For this purpose, the multiple-split-cathode-with-different-slit-angle method is used to perform measurements of the linear current distribution of the arc root in seven different directions. On the basis of the measurement results, a large system of linear algebraic equations is treated with...
