Selected service-discovery systems allow clients to issue multicast queries to locate network devices and services. Qualifying devices and services respond directly to clients; thus, in a large network, potential exists for responses to implode on a client, overrunning available resources. To limit implosion, one service-discovery system, UPnP, permits clients to include a jitter bound in multi...

For many service discovery protocols, user service queries need to be disseminated to some service directories within the system for discovering matched services. The scope of dissemination identifies the scope of service discovery. How to determine the service discovery scope needs to be discussed. In this paper, we present a service query dissemination algorithm in our developing service disc...

Nowadays, portable electronic devices allow users to access available resources wherever they are. In this sense, announcement and discovering of services and resources are two central problems to be solved in ubiquitous computing. Despite the fact that many service and resource discovery protocols exist, they are limited to a concrete network technology and most of them do not face mobility an...

In this work we present a service discovery system that supports flexible queries using partial keywords and wildcards. It is built upon a Chord network and it guarantees that any existing data that match a query is found. The main feature of this service is to use a proxy server layer with a mechanism for data distribution that reduces the number of nodes involved in the searching process.

The past few years have seen the Grid is evolving as a service-oriented computing infrastructure. It is envisioned that various resources in a future Grid environment will be exposed as services. Service discovery becomes an issue of vital importance for utilising Grid facilities. This paper presents RSSM, a Rough Sets based service matchmaking algorithm for service discovery that can deal with...

This paper presents our research progress for group context-aware service discovery supporting continuous service availability by providing an alternative service. We believe that service discovery system need to have efficient method for representing the context of a service and a good algorithm for matching and evaluation. We adopt IOPE model from Semantic Web to represent service context and...

[1] The emergence of digital evidence and the widespread implementation of e-discovery has brought both benefit and repercussion. In many respects, digital evidence has proven to be a better truth detector than its paper counterpart. At the same time, the volumes in which digital evidence exists make time-tested discovery techniques impractical. In fact, so significant are the technological dif...

Houshang Golshiri is among the Iranian leading creative and imaginative fiction writers who managed to open up new horizons in Iranian fiction. Hence he could be claimed to be an innovative avant-garde short story writer with unique stylistic characteristics. Although inspired by fiction writers such as Alavi, Sadeqi, Golestan and Sa'edi in the techniques of narration, Golshiri nonetheless stan...

Beside Ziegler-Natta and Phillips catalysts the development of methylaluminoxane (MAO) as cocatalyst in combination with metallocenes or other transition metal complexes for the polymerization of olefins has widely increased the possibilities in controlling the polymer composition, polymer structure, tacticity and special properties with high precision. These catalysts allow the synthesis of is...
