Ontology is the backbone of Semantic Web. Ontology has drawn more and more concerns with the research works developing in the Semantic Web. The construction of large-scale ontologies will involve collaborative efforts of multiple developers. In this paper, we give a demonstration of our Cooperative Ontology Development Environment CODE and discuss a demo(More)
In this paper, we propose an algorithm for unconstrained optimization that employs both adaptive trust region techniques with line searchs. Unlike traditional adaptive trust region methods, our algorithm does not resolve the sub problem if the trial step isn’t accepted, but instead performs the Wolfe line search at each iteration. Under mild(More)
Motion objects detection is a process of segmenting the motion objects or regions from the rest of the sequent images. This paper presents an approach to motion objects detection by applying wavelet clustering with frame difference, which satisfies some requirements of rapid motion objects detection. By analyzing adjacent frame difference results and(More)
Complex nonlinear economic dynamics in a Cournot duopoly model proposed by M. Kopel is studied in detail in this work. By utilizing the topological horseshoe theory proposed by Yang XS, the authors detect the topological horseshoe chaotic dynamics in the Cournot duopoly model for the first time, and also give the rigorous computer-assisted verification for(More)
