Discovering and composing services is a core functionality of a service-oriented software system. Semantic web services promise to support and (partially) automate these tasks. But creating semantic service specifications is a difficult, time-consuming, and error prone task which is typically performed by service engineers. In this paper, we present a community-based approach to the creation of...

Started from the very beginning, Stemming has been playing significant roles in several Natural Language Processing Applications such as information retrieval (IR), machine translation (MT), morph analysis and deciding the part of speech (POS). Several stemmers have been developed for a large number of languages including Indian languages; however no work has been done in Kokborok, a native lan...

This paper reports a practical experience of implementing a group communication service using a protocol composition framework. Specifically, the paper describes the implementation of a Light-Weight Groups (LWG) service on the Ensemble system. This is an interesting case-study because the LWG service is very demanding in terms of protocol composition since its implementation requires the use of...

The virtual synchrony model for group communication has proven to be a powerful paradigm for building distributed applications. Implementations of virtual synchrony usually require the use of failure detectors and failure recovery protocols. In applications that require the use of a large number of groups, significant performance gains can be attained if these groups share the resources require...

A series of secreted proteases are included among the virulence factors documented for Staphylococcus aureus. In light of increasing antibiotic resistance of this dangerous human pathogen, these proteases are considered as suitable targets for the development of novel therapeutic strategies. The recent discovery of staphostatins, endogenous, highly specific, staphylococcal cysteine protease inh...

Peroxyoxalate system includes an oxalate ester, peroxide and a fluorescer, The energy resulted from the reaction of oxalate ester and peroxide is transferred to fluorescer and cause it to fluorsc. The effect of reactants chemical structure, their concentration, solvent media (polarity and viscosity) and the temperature, on the intensity of the illuminated light with respect to time have bee...
