in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.

In this paper, a class of uncertain nonlinear multi-agent systems with unknown control directions and dead-zone fault is addressed, where gains exist in each subsystem. terms the approximation characteristic fuzzy logic system, it used to approximate dynamics, then relevant adaptive laws are designed. Considering presence fault, Nussbaum gain function technique introduced design intermediate la...

Hospitals are one of the most important public amenities in cities. The location hospitals is critical for residents' accessibility, as case with all other amenities. However; such parks, and schools provide services at neighborhood scale, serve entire city. Therefore, deciding where to locate a hospital complex issue that requires consideration various criteria. purpose this study create multi...

The purpose of this paper is to study soft sets and soft topological spaces. We also introduce the concepts of soft interior point, soft interior, soft neighborhood, soft continuity and soft compactness. The relationships between soft topology and fuzzy topology are also provided. Also, some basic properties of these concepts are explored. 2010 AMS Classification: 06D72, 54A40

The Fuzzy Adaptive Neighborhood Search (FANS) method was previously presented and succesfully compared against a genetic algorithm and simulated annealing doing minimization of functions in Rn. Here we propose to evaluate FANS on instances of knapsack with multiple restrictions problems, making comparison against the cited algorithms in order to gain knowledge about the behaviour of our method.

Using a D0-brane as a probe, we study the spacetime geometry in the neighborhood of N D-branes in matrix theory. We find that due to fermionic zero modes, the coordinates of the probe in the transverse directions are noncommutative, and the angular part is a fuzzy sphere.

A theory of granular computing is presented. Some classical example are examined to obtain the hint of new directions Obvious examples are dynamic programming, fuzzy numbers, infinitesimal number and access control model, (pre)topological spaces are examined; Localized multi-level granulation can be modeled by generalized topological spaces, called neighborhood systems. For most general granula...

A new feature description method based on the fusion of fast retina keypoint (FREAK) and rotation-aware binary robust independent elementary features (rRBRIEF) is proposed to realize effective combination efficiency accuracy two descriptions. In addition, in elimination stage mismatched point pairs, by setting base its neighborhood, an improved neighborhood parallel random sample consensus (RAN...

This brief investigates the fixed-time trajectory tracking control problem for unmanned surface vehicle with unknown dynamics based on command filtered backstepping technique and stability theory. Distinct from existing results where execution is periodic computational burden overlarge, a novel event-triggered adaptive practical fuzzy controller designed to guarantee of closed-loop system (CLS)...
