The aim of this paper is to develop an effective method for solving matrix games with payoffs of triangular fuzzy numbers (TFNs) which are arbitrary. In this method, it always assures that players’ gain-floor and loss-ceiling have a common TFN-type fuzzy value and hereby any matrix game with payoffs of TFNs has a TFN-type fuzzy value. Based on duality theorem of linear programming (LP) and the ...

The effect of an external non-uniform rotating magnetic field (RMF) on the thermocapillary flow in a liquid bridge under microgravity is studied numerically. The thermocapillary flow subject to a non-uniform RMF (7mT, 25Hz) is investigated over a range of Marangoni numbers (15-40). The results indicate that, in comparison with the thermocapillary flow without the magnetic field, the maximum tan...

A system of prefabricated vertical drains (PVDs) with a surcharge load is an effective method for accelerating soil consolidation by promoting radial flow. This study presents a three-dimensional (3D) finite element model for soft soil improved by a single drain. In the finite element analysis, the actual rectangular PVD cross-section is considered, and the equivalent drain diameter is then bac...

Machine tool selection is a very complex procedure. It involves deep analysis of various factors affecting functioning and performance. CNC machine tool selection is also a such kind of problem[5]. Objective of this study is to perform various MCDM methods for selecting most appropriate machine tool. AHP method is used to calculate the weights of various criteria[10] . The numerical problem con...

To organize a huge amount of Web pages into topics, according to their relevance, is the efficient and effective method for information retrieval. Latent Semantic Space (LSS) naturally in the form on some geometric structure in Combinatorial Topology has been proposed for unstructured document clustering. Given a set of Web pages, the set of associations among frequently co-occurring terms in t...

Railway ballast tamping operation is employed in order to restore the geometry of railway track distorted by train traffics. In this paper, based on analysis of tamping principle, the discrete element analysis model of railway ballast is created using the discrete element method, numerical simulations are performed to study the change of railway ballast compactness during tamping process. This ...

India being an agro-based economy, farmers experince alot of problem in detecting andpreventing diseases in fauna. So there is a necessacity in detecting diseases in fauna which proves to be effective and conviennent for researchers. Relying on pure naked-eye observation to detect and classify diseases can be very unprecise and cumbersome. The color and texture features are used to recognize an...

In this chapter, we examine the problem of Web community identification expressed in terms of the graph or network structure induced by the Web. While the task of community identification is obviously related to the more fundamental problems of graph partitioning and clustering, the basic task is differentiated from other problems by being within the Web domain. This single difference has many ...

One of the many areas in which Correspondence Analysis (CA) is an effective method, concerns ordination problems. For example, CA is a well-known technique for the seriation of archaeological assemblages. A problem with the CA seriation solution, however, is that only a relative ordering of the assemblages is obtained. To improve the usual CA solution, a constrained CA approach that incorporate...

Effective power saving mechanism is the most significant issue for extending the lifetime of mobile stations in wireless metropolitan area network (MAN). In this paper, we propose an effective method to analyze the system performance of the power saving class type II in IEEE 802.16e. We present a queueing model with two kinds of vacation mechanisms to capture the working principle of the networ...
