We study the problem of optimally partitioning scrambled genes of stichotrichous ciliates into their relevant functional segments, and of aligning scrambled genes with non-scrambled genes. This problem is significantly more difficult than traditional sequence alignment due to the patterns that occur in the scrambled genes. Here, a formal model is created to capture this problem. Then, the inherent...
There is a rapidly growing interest in corporate social responsibility (CSR), especially in the current global financial crisis. We briefly review the development of CSR and point out in China the research is quite frequently immature and heavily qualitative. To facilitate the development, we propose a quantitative way to measure CSR and formulate CSR in a multiple objective portfolio selection model...
Aiming at the risk management that electricity purchasers will face in power purchase of four markets under the framework of the electricity market, two purchasing electricity models about the restrictions or non-restriction are set up by means of Variance measuring risk. Meanwhile, this paper also proposes several feasible algorithms to minimize risks, including statistical genetic algorithms (SGA)...
The two-level synthetical evaluating model is presented in this paper based on the factors of substance and people which affect the industrial product model design and the fuzzy feature existed in the mobile phone model evaluation. And a synthetical evaluation system is formed as to mobile phone by the way of the radial basis function neural network. And it gained a good result from evaluating. Experimental...
The segmentation of brain magnetic resonance (MR) images is of great significance in research and clinical applications, including diagnosis of pathology, presurgical planning and computer integrated surgery. To cope with the inevitable intensity in homogeneity problem of MR images, based on the techniques of curve evolution and level sets, a novel curve evaluation method employing neighboring information...
Service Component Architecture (SCA) provides a language-independent way to define and compose service component. The SCA assembly model should be reliable. This target can be reached by translating a formal signature model and behavior model for SCA to Promela, and Promela specifications are then verified with the model checker SPIN. SCA complements some service composition languages (such as BPEL)...
This paper proposes a mesh simplification method based on facial features region partition for the special three-dimensional facial mesh model. According to distribution of feature points, the face is divided into several parts consisting of critical feature regional and non-critical feature regional. This method adjusts different areas using different curvature values. This algorithm also uses edge...
Task scheduling is one of the core problems in grid computing. How to accomplish tasks quickly and efficiently to meet users' requirements has always been being a hot issue in the fileds of theoretical and applied research. The algorithm presented in this paper is based on the ant colony algorithm and genetic algorithm. It realizes scheduling optimization for grid tasks by studying and exploring optimization...
