In this paper we are interested in a class of fuzzy numbers which is uniquely identified by their membership functions. The function space, denoted Xh,p, will be constructed combining nonlinear mappings h (subjective perception) and probability density functions (PDF) p (objective entity), respectively. Under our assumptions, prove that there always exists to fulfill the observed outcome for gi...

Cloud computing is the technology that provides different types of services as a useful resource on Internet. Resource trust value will help cloud users to select provider for processing and storing their essential information. Also, service providers can give access based secure resources from malicious users. In this paper, models are proposed, which comes under subjective model behavior user...

A hybrid method combining an evolutionary search strategy, interval mathematics and pole assignment-based closed-loop control synthesis is proposed to design a robust TSK fuzzy controller. The design objective is to minimize the number of linear controllers associated with rule conclusions and tune the triangular-shaped membership function parameters of a fuzzy controller to satisfy stability a...

Load forecasting is essential for planning and operation in energy management. It enhances the Energy efficient and reliable operation of a power system. The energy supplied by utilities meets the load plus the energy lost in the system is ensured by this tool. Since in power system the next day’s power generation must be scheduled every day. The dayahead short term load forecasting (STLF) is a...

An adhesive-bonded single lap joint is analyzed using a new fuzzy finite element model. In the model, Young’s moduli and Poisson’s ratios of the joint materials are taken as fuzzy numbers in order to take the uncertainty of the material properties into account. The fuzzy numbers are modeled using linear triangular membership functions. At a selected material point in the adhesive layer, the pos...

We present an algorithm that, given a subgroup G of the group of the upper triangular matrices with rational entries by a set of generators, computes generators of the lower central series of G. As an application, we show that the constructive membership problem in G can be performed in polynomial time. This draft is intended to be part of a larger project investigating the complexity of comput...

Fuzzy approach to control congestion in ATM networks is inevitable in research areas. . A control scheme that dynamically regulates traffic flow according to changing network conditions however requires the understanding of network dynamics. To minimize congestion, for a gradual change we proposed fuzzy approach. In our scheme, burst length as well as buffer occupancy are represented by triangu...

Uncertain set theory is a generalization of uncertainty theory that has become a new branch of mathematics for modeling human belief degrees. Uncertain set is a fundamental concept to describe unsharp concepts in uncertain set theory. The moments are important characteristics of an uncertain set. This paper studies the moments and central moments of uncertain set and gives some formulas to calc...

We consider pattern matching problems where patterns are presented as sequences of fuzzy constraints on input elements. Given an infinite alphabet A, a pattern P [α,β] is a sequence ­ μi1 , μi2 , ..., μim ® of membership functions μij defined on A. The pattern P fuzzy matches an input sequence t ∈ A∗ if t = ux1x2 · · ·xmv such that
