for any agency dealing with the design of the water distribution network, an economic design will be an objective. in this research, central force optimization (cfo) and differential evolution (de) algorithm were used to optimize ismail abad water distribution network. optimization of the network has been evaluated by developing an optimization model based on cfo and de algorithm in matlab and ...

The development and proliferation of mobile social networks have the potential to transform ways that people come together and interact in public space. These services allow new kinds of information to flow into public spaces and, as such, can rearrange social and spatial practices. Dodgeball is used as a case study of mobile social networks.

This paper examines how combining narrative research methods with an actor-network perspective is valuable for the process-oriented field studies that adopt an ensemble-view of technology. In response to a call by senior IS researchers to theorize the IT artifact, the paper draws on five premises previously identified as a basis for more seriously engaging such artifacts. The paper synthesizes ...

Background. The implementation of the new modern services on existing networks requires replacement or modernization old equipment.

Therefore, issues/tasks implementing SDN technology in construction are center attention representatives science-research organizations telecom operators. have advantages flexible scaling...

Building a safety case is a common approach to make expert judgement explicit about safety of a system. The issue of confidence in such argumentation is still an open research field. Providing quantitative estimation of confidence is an interesting approach to manage complexity of arguments. This paper explores the main current approaches, and proposes a new model for quantitative confidence es...
