The evolution in the semiconductor industry leading to constant increase in the clock speeds and increase in device density and the advent of reconfigurable hardware have paved the way to the creation of a new generation of very agile reprogrammable communication systems generically known as Software Radio (SR) platforms. SR uses a mix of fixed and programmable and/or reconfigurable hardware en...

1389-1286/$ see front matter Crown Copyright doi:10.1016/j.comnet.2011.05.012 E-mail address: [email protected] We survey the state-of-the-art technologies in Wavelength Division Multiplexing (WDM) network reconfiguration. Our focus is the strategies and triggering methods. We compare the proposed technologies in the literature from different perspectives: traffic-changes triggered vs. other ev...

tirgan formation with lower cretaceous age (barremian-aptian) in the kopet-dagh basin consists of carbonate and siliciclastic rocks (calcareous shale and sandstone) which conformably lay between siliciclastic rocks of shurijeh formation below, and marly sarcheshmeh formation at the top. in this study, tirgan formation in two stratigraphic sections of abgarm (77 m in thickness) and sirzar (46 m ...

This paper presents a simulator for modeling dynamic reconfiguration of component-based interconnection networks. It is able to model and simulate all kinds of interconnection networks that are composed of switches, buffers, sources, and destinations. Steady-state simulation can be applied as well as terminating simulation to observe any transient behavior of the network. Due to the involved st...

On-line reconfiguration is the ability to rearrange dynamically the elements of a system to accommodate failure events or new requirements. Due to the modular representation, decentralized discreteevent approach, recently proposed for the diagnosis of systems, is particularly well suited to the diagnosis of reconfigurable systems. The contribution of this article is to extend our decentralized ...

The Semantic Web could be a crucial tool to terrorism researchers, but to achieve this potential an accessible and flexible but comprehensive ontology needs to be designed to describe terrorist activity. Terrorist events are complicated phenomena that involve a large variety of situations and relationships. This paper addresses some of the issues the authors have encountered trying to build suc...

Switching between two different tasks normally results in an impairment in people's performance known as a switch cost, typically measured as an increase in reaction time (RT) and errors compared to a situation in which no task switch is required. Researchers in task switching have suggested that this switch cost is the behavioural manifestation of the task set reconfiguration processes that ar...

This paper discusses dynamic reconfiguration of applications at the architectural level. Current work on dynamic aspects of software architectures has focused on planned reconfigurations controlled from the outside. In this paper we present a different approach, using architectural agents. The agent-enabled architecture descriptions will be executable and have a mechanism to describe reconfigur...

topology is being reconfigured to be more adaptive. It can reduce network congestion flow, and the ratio of information loss. So, the efficiency of network is improved[1,2]. e study the issues when considering the problem of configuring WDM networks in response to changes the traffic patterns. As traffic patterns change, rtual topology of network is reconfigured to adapt the affic requests. The...
