We consider the application of Dantzig-Wolfe decomposition to stochastic integer programming problems arising in the capacity planning of electricity transmission networks that have some switchable transmission elements. The decomposition enables a column-generation algorithm to be applied, which allows the solution of large problem instances. The methodology is illustrated by its application t...

Collision-free transmission and efficient data transfer between nodes can be achieved through a set of channels in multichannel wireless sensor networks (MWSNs). While using multiple channels, we have to carefully consider channel interference, channel and time slot (resources) optimization, channel switching delay, and energy consumption. Since sensor nodes operate on low battery power, the en...

There is currently a national push to create a smarter, more flexible electrical grid. Traditionally, network branches (transmission lines and transformers) in the electrical grid have been modeled as fixed assets in the short run, except during times of forced outages or maintenance. This traditional view does not permit reconfiguration of the network by system operators to improve system perf...

We delineate critical issues for “controlling light with light” in photonic crystal PC waveguides coupled to Kerr-nonlinear microresonators. These arise from a fundamental trade-off between switching speed and switching intensity threshold inherent in high-quality Q-factor cavities and b the dynamical nonlinear oscillation of such cavities in response to incident light pulses. Using finite-diff...

Network connectedness is indispensable for the normal operation of transmission networks. However, there still remains a lack efficient constraints that can be directly added to problem formulation optimal switching (OTS) ensure network strictly. To fill this gap, brief proposes set linear by leveraging equivalence between and feasibility vertex potential equation an electrical flow network. Th...

In this paper, we propose a real-time communication scheme that can be used in general point-to-point real-time multicomputer systems with wormhole switching. Real-time communication should satisfy the two requirements of predictability and priority handling. Since traditional wormhole switching does not support priority handling, which is essential in real-time computing, flit-level preemption...

Growing demand for electric power seems to necessitate new transmission lines, but obstacles to building these new lines are often extremely high. At the same time there is a national push for a “smarter” bulk electric grid, one that is more controllable and flexible. Optimal transmission switching is a straightforward way to leverage grid controllability: to make better use of the existing sys...
