In this paper, we recommend and promote global standards of the e-Trade process on the basis of ebXML & web services. For the ebXML Frameworkbased e-Trade to be facilitated, it is urgent for each country to implement and use national ebXML registry and standardize electronic documents, electronic catalog and electronic payment. In UNCEFACT, ebXML-based UN Central Registry & Repository is in the...

This paper is concerned with the design of a wireless data transmission which provides Un-equal Error Protection (UEP). A novel Superposition Multi Rate Coded Modulation (SMRCM) system has been introduced. In the proposed SMRCM, the user data bit stream can be divided into two bit streams. The first bit stream represents the region of High Priority (HP), while the second represents the region o...

In this paper, we deal with a simple geometric problem: Is it possible to partition rectangle into k non-congruent rectangles of equal area? This problem is motivated by the so-called ‘Mondrian art problem’ that asks similar question for dissections integer sides. Here, generalize Mondrian allowing real case, show minimum value have ‘perfect partition’ (that is, equal-area rectangles) seven. Mo...

We give a complete invariant for finite-dimensional Hopf C*-algebras. Algebras that are equal under the invariant are the same up to a Hopf *-(co-anti)isomorphism. Résumé. On donne un invariant complet pour les C*-algèbres de Hopf
