A composite Web service, such as arranging a travel to a conference, can be viewed as a project team that is comprised of several members who want to collaborate in order to accomplish a specific goal. In this work, we propose an algorithm for searching a social network of Web services in order to select an effective set of Web services that can collaborate in order to attain the main goal of t...

Because of the need to develop specific measurement scales for different services industries, this study aimed to empirically develop a reliable and valid model specifically for measuring mobile telecommunication service quality. A multidimensional measurement model (MS-Qual) has been proposed based on an extensive literature review and then, to assess the model validity, convergent and discrim...

We present the first optimal randomized online algorithms for the TCP acknowledgment problem [3] and the Bahncard problem [5]. These problems are well known to be generalizations of the classical online ski-rental problem, however, they appeared to be harder. In this paper we demonstrate that a number of online algorithms which have optimal competitive ratios of e/(e − 1), including these, are ...

The schema and its associative labels have also given rise to a loss of voice for the elderly in that ...
