key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. to establish a secure communication, two nodes must share common key from their key-rings. otherwise, they can find a key- path in which ens...

Disk images play a critical role in multi-tenant datacenters. In this paper, the first study of its kind, we analyze operational data from the disk imaging system that forms part of the infrastructure of the Emulab facility. This dataset spans four years and more than a quarter-million disk image loads requested by Emulab’s users. From our analysis, we draw observations about the nature of the ...

The major oil industry upstream activities include the exploration, drilling, extraction, pipelines installation, and production of crude oil. In this paper, we develop a mathematical model to plan for theseoperations as a crude oil supply chain network design problem.The proposed multi-period mixed integer linear programming model entails both strategic (e.g., facility location and allocation)...

Network of public spaces composes of a network of interconnected land use and various elements of the city, such as synthetic and natural which shows the city as a whole. Network structure of public spaces is important because understanding this network as a structure presents us the formation of the city. This paper attempts to define the status of the network of public spaces in the city stru...

This article describes an intelligent system called LogNet that provides advice on how to design business logistics networks. It implements its capabilities by utilizing model-based reasoning techniques. In addition, it utilizes heuristic-based searching to guide an end-user toward more effective network designs. The network design problem studied in this article addresses the warehouse facilit...

Abstract Phase Data Concentrator (PDC) is an important part of Wide Area Measurement System (WAMS) and widely used in transmission systems. WAMS technology will also be applied smart distribution network, which has many nodes, complex architecture various types data services, a single communication mode cannot meet its needs. In order to solve this problem, paper first introduces the compositio...
