E-learning platform evaluation is one of the most important issues in e-learning platform management. It is a multi-criteria decision problem including various factors. Traditional methods have many shortcomings. Fuzzy AHP model is established to solve this problem. A general evaluation method is provided and steps are presented. As a case study, the model is implemented and a detailed example is...
A software project risk identification process based on Genetic Algorithms (GA) is presented in this paper. The risk identification process utilizes GA to search the rules of risk identification based on historical data in software project in order to identify the risks in the process of software project development. The application process of GA in risk identification is analyzed in the paper. Finally,...
A risk evaluation model in software project investment based on Bayesian networks (BNs) is presented in this paper. The BNs parameter learning is applied to the modeling process based on sample data set, so that the BNs is more accordant with the project feature in the software project investment phase. In addition, the validity of the parameter learning is validated with algorithm precision and convergence...
Morphosys is a reconfigurable single instruction multiple data (SIMD) architecture mainly composing of host core processor, reconfigurable cells array, frame buffer, context memory and direct memory access (DMA) module. As a common SIMD-based coarse-grained reconfigurable architecture, each context configuration and operation is based on the whole row or column function, which may be inefficient in...
Rough concept lattice (RCL) is a new concept lattice, which can deal with uncertainty knowledge. It is an effective tool for data analysis and knowledge discovery. But some objects that in upper approximation extent of RCL are so uncertainty that makes the accuracy of association rules reduced. In this case, based on decision context, we construct a L- plumpness concept lattice (Lp - RCL), in whose...
Random walk (RW) has been widely used as a strategy for searching in peer-to-peer networks. The boom of social network applications introduces new impact to the classical algorithms on the Internet. In this paper, we model the random walk algorithm in peer-to-peer networks when social information is available. We define the social relationship between two nodes as the knowledge about the resources...
Ruby on Rails (RoR) has developed rapidly since the release of RoR 1.0. With the popularization of RoR, more and more development tools supporting RoR emerged. In this paper, we compare and analyze several main RoR development tools based on our experience of using those tools, which can help RoR developers select the most suitable tools according to their technical background and programming preference.
