Collaborative design provides creative design solutions and improves product quality as well as enriches participants’ knowledge. Nevertheless, design and supply chain integration in product development processes is not a trivial task. The complex scenario of the dynamic extended enterprise triggers research toward the development of an innovative co-design platform to support multidisciplinary...

Web search engines are one of the most popular tools on the Internet which are widely-used by expert and novice users. Constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. Query expansion is a way to reduce this concern and increase user satisfaction. In this paper, a new method of query expa...

in this paper, based on sinh-cosh method and sinh-gordon expansion method,families of solutions of (2+1)-dimensional breaking soliton equation are obtained.these solutions include jacobi elliptic function solution, soliton solution,trigonometric function solution.

This report presents a new proof method of partial correctness for logic programs with negation based on a proof modularity. We prove in a com-positional way that Fitting's or the well-founded semantics of the program is included in a speciication. We give conditions for an abstract semantics to be compositional and we base our proof method on this property. We present also conservative but com...

An Extended Enterprise (EE) is a new form of organizing Business-to-Business (B2B) cooperation among business partners. Here, independent companies form a network to develop and deliver a product to a customer. An EE extends the concept of a virtual enterprise because it persists even after the product is delivered. Thus, the EE serves as a container for knowledge captured during product develo...

For the edge e = uv of a graph G, let nu = n(u|G) be the number of vertices of G lying closer to the vertex u than to the vertex v and nv= n(v|G) can be defined simailarly. Then the ABCGG index of G is defined as ABC...
