The contingencies contribute to overloading of network branches and unsatisfactory voltages, which may lead to problems of stability/voltage collapse. The most important task in security analysis is the problem of identifying the critical contingencies from a large list of credible contingencies and rank them according to their severity. This paper presents fuzzy approach for ranking the contin...

In this paper, we elaborate how decision space diversity can be integrated into indicator-based multiobjective search. We introduce DIOP, the diversity integrating multiobjective optimizer, which concurrently optimizes two set-based diversity measures, one in decision space and the other in objective space. We introduce a possibility to improve the diversity of a solution set, where the minimum...

We present Conchord, a system for real-time automatic generation of musical harmony through navigation in a novel 12-dimensional Tonal Interval Space. In this tonal space, Euclidean distances among multi-level pitch configurations equate with their perceptual proximity, and Euclidean distances of pitch configurations from the center of the space acts as an indicator of consonance. Building upon...

Traditionally, implicit feedback measures are used to evaluate the performance of a particular information retrieval system. This research instead takes a distinctly applied approach to the use of implicit feedback, and extends the inference from aggregate query data to the social and political sciences. Using the three months prior to the 2008 election as a test scenario, the analysis here ass...

in this paper, using the best proximity theorems for an extensionof brosowski's theorem. we obtain other results on farthest points. finally, wedene the concept of e- farthest points. we shall prove interesting relationshipbetween the -best approximation and the e-farthest points in normed linearspaces (x; ||.||). if z in w is a e-farthest point from an x in x, then z is also a-best ...

Homogenization of electromagnetic periodic composites is treated as a two-scale problem and solved by approximating the fields on both scales with eigenmodes that satisfy Maxwell's equations and boundary conditions as accurately as possible. Built into this homogenization methodology is an error indicator whose value characterizes the accuracy of homogenization. The proposed theory allows one t...

Tipping points are crossed when small changes in external conditions cause abrupt unexpected responses in the current state of a system. In the case of ecological communities under stress, the risk of approaching a tipping point is unknown, but its stakes are high. Here, we test recently developed critical slowing-down indicators as early-warning signals for detecting the proximity to a potenti...

Graphs are a natural way to represent multi-relational data and are extensively used to model a variety of application domains in diverse fields ranging from bioinformatics to homeland security. Often, in such graphs, certain subgraphs are known to possess some distinct properties and graph patterns in the proximity of these subgraphs can be an indicator of these properties. In this work we foc...

Transparent authentication (TA) schemes are those in which a user is authenticated by a verifier without requiring explicit user interaction. Those schemes promise high usability and security simultaneously. Many TA schemes rely on the received signal strength as an indicator for the proximity of a user device (prover). However, such implicit proximity verification is not secure against an adve...

The main purpose of this paper is to study the approximate best proximity pair of cyclic maps and their diameter in fuzzy normed spaces defined by Bag and Samanta. First, approximate best point proximity points on fuzzy normed linear spaces are defined and four general lemmas are given regarding approximate fixed point and approximate best proximity pair of cyclic maps on fuzzy normed spaces. U...
