We describe the architecture and design of an optical WDM ring network suited to local, campus and metropolitan area applications. The proposed architecture is flexible and robust, is compatible with existing local and metropolitan area network standards, has the potential for low-cost implementation and offers an elegant upgrade path to larger numbers of nodes and higher bit rates. We discuss ...

the term globalization undoubtedly has affected all parts of humanity life in current century. globalization as a comprehensive phenomenon has influenced economical, political, social and cultural aspects of our societies. contemporary architecture as a multidimensional category is depended on various factors and needs to be pursued in different fields, in order to reach to a perfect comprehend...

traditional houses enjoy an organizing with inner spaces based on religious and traditional notions of iranian families. space flexibility, readability, introversion, spatial hierarchy and family privacy have had a special status in architecture of iranian houses, replaced with an outward-oriented architecture. the traditional architecture which has had all the necessary spaces for any communic...

This document describes an architecture to support the debugging of parallel and distributed (PVM) applications. It also presents the set of system calls supported by the debugging engine. 1 System architecture The figure ?? presents the architecture and interaction(s) between the GRAPNEL Execution Environment and the debugging engine. (local deamon) process

Lots of industrial tasks need contacts between operators and a central Information Management System. Permanent contact creates a more effective and efficient workforce with a direct update in the central Information Management System. In the case of mobile operators (e.g. warehouses or picking operators), this can be realized thanks to electronic remote devices connected to a private wireless ...

This article discusses practices, opportunities and challenges in local eGovernment project management; the development towards eGovernment and “the 24/7 agency”. Analyzing a case against eGovernment success factors we find seven “critical issues”; political timing, resource allocation, political mandate, distinction between administrative and political responsibilities, coordination of departm...

Valuation algebras are the foundation of a widespread theory unifying different fields of modern research and culminating in the power of local computation. Although this theory rejoys in great interest from a pure theoretical perspective, many questions were originally motivated by practical experiences. The aim of this paper is to return to this practical starting point by illustrating how th...

The use of optical fiber as a transmission medium in computer local area networks (LAN) has lead to the design of new protocols to take advantage of the high bandwidth of fiber. Many of these new protocols have been designed for a ring topology LAN. There has also been significant research effort devoted to designing protocols for a star topology LAN. This paper proposes a novel hybrid architec...

With the rapid growth of next generation sequencing technologies, such as Slex, more and more data have been discovered and published. To analyze such huge data the computational performance is an important issue. Recently, many tools, such as SOAP, have been implemented on Hadoop and GPU parallel computing architectures. BLASTP is an important tool, implemented on GPU architectures, for biolog...
