Electronic contracts describe inter-organizational business processes in terms of supply and consumption of electronic services (commonly Web services). In a given contract domain, it is usually possible to identify a set of welldefined common and variation points. Feature modeling is an ontology-like technique that has been widely used for capturing and managing commonalities and variabilities...

This paper proposes a suitable method for simulating impulses with appropriate amplitude, spectral, and inter-arrival characteristics. The statistics used to develop the parameters of this model are based on statistics derived from observations of impulse noise on the telephone networks of British Telecom (BT) and Deutsche Telekom (DT). This paper initially reviews the former DT approach to imp...

Evaluation is a basic requirement to protect telecom data networks. How to carry out a usable evaluation is a main problem to solve in this paper. The index system is the basis of the analysis. The general framework is combined with the structure of China telecom data network to get the index system. The evaluation method is established based on the score of index system. The score is obtained ...

Today, telecom operators face a threefold challenge: a social challenge dealing with the evolution of the consumer lifestyle, a technological challenge dealing with ever changing ICT trends and a business challenge dealing with the need for innovative business models. This paper introduces an idea of group-oriented services, a special type of personalized telecom services, as a possible solutio...

The present status of the problem of neutrino mass, mixing and neutrino oscillations is briefly summarized. The evidence for oscillations of atmospheric neutrinos found recently in the Super-Kamiokande experiment is discussed together with the results of the solar neutrino experiments and the accelerator LSND experiment.
