Control and Cybernetics Fuzzy Regions: Interpretations of Surface Area and Distance *
نویسندگان
چکیده
This contribution concerns the modelling of fuzzy information in geographic databases. For this purpose, fuzzy regions and fuzzy points have been defined in the past, along with a number of suitable operations. For numerical information such as the surface area of fuzzy regions, or the distance between fuzzy regions and/or fuzzy points the computation depends on the interpretation given to the fuzzy regions or points. Consequently, it is important to differentiate between the interpretation in order to obtain correct results. This article explains in detail the impact of the interpretation in terms of both the surface area and the distance.

Comparing the Analytic Hierarchy Process (AHP) and fuzzy logic for zoning the risk of gully erosion in the three regions of the Ardebil province
Gully erosion is the most advanced water erosion in watersheds that produce large volumes of sediment can cause serious damage. In order to manage and cope with this type of erosion, to identify areas of high risk of gully erosion in the watershed is very important. For this purpose gully erosion hazard zonation maps by combining information layers of different factors affecting the formation o...
متن کاملFuzzy systems evaluation: The inference error approach
An inference method based on an equation image of a rule-base and the minimization of a cost index (inference error) is presented. The method has several advantages: it has intuitive insight, allows more powerful rules, and also presents an interesting algebraic (minimum distance) and functional (subsethood) formulation of the meaning of inference. Analysis of internal quality and completeness ...
متن کاملAdaptive fuzzy sliding mode controller for linear systems with mismatched time-varying uncertainties
A new design approach for an adaptive fuzzy sliding mode controller (AFSMC) for linear systems with mismatched time-varying uncertainties is presented. The coefficient matrix of the sliding function can be designed to satisfy a sliding coefficient matching condition provided time-varying uncertainties are bounded. With the sliding coefficient matching condition satisfied, an AFSMC is proposed t...
متن کاملLiving windbreak design for wind erosion control in arid regions: A case study in Dehloran, Iran
Wind erosion is considered as one of the main processes of land degradation in different parts of the world. Among the most effective ways to control wind erosion is to cover land surface with natural vegetation area. In this study, 3 replica soil samples were collected, at a depth of 0-3 cm, from various land uses in Dehloran, Ilam Province, Iran. Physical and chemical characteristics of soil ...
متن کاملA fuzzy approach to elevator group control system
The elevator group control systems are the control systems that manage systematically, three or more elevators in order to efficiently transport the passengers. In the elevator group control system, the area-weight which determines the load biases of elevators is a control parameter closely related to the system performance. This correspondence proposes a fuzzy model based method to determine t...
