in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...

Abstract This article studies closeness between indicators that local governments use to monitor Sustainable Development Goal (SDG) implementation in their Voluntary Local Reviews (VLRs) and those included the standardised set of European Handbook for SDG Reviews. To do so, it develops an index ‘indicator proximity’ through a qualitative semantic comparison 2354 used sample 29 VLRs 72 Handbook’...

Collaboration and the exchange of knowledge is supposed to be eased by geographical proximity because of the tacit character of knowledge. Recently a number of scholars criticized this view on geographical proximity for being oversimplified and argue that the precise role of geographical proximity for knowledge exchange and collaboration still remains unclear. This paper analyses the role of ge...

Background and Aim: Due to the importance of scientific relations between university and industry, it is so important to identify the factors that affect these relations. So,the aim of this study is to investigate the effect of spatial proximity on university- industry collaboration. The collaboration indicator which is used here is University- Industry Co-publications. Methods: The research is...

In this paper, we propose a parametric model for multivariate distributions. The model is based on distortion functions, i.e. some transformations of a multivariate distribution which permit to generate new families of multivariate distribution functions. We derive some properties of considered distortions. A suitable proximity indicator between level curves is introduced in order to evaluate t...

This paper presents a newly developed proximity indicator for voltage stability assessment which can be used to predict critical real system load and voltages at various buses loading point. The varies almost parabolic with total demand reaches orthogonally axis. relation has been utilized It shown that two operating points are needed estimating point proper selection of variation near collapse...

This paper tests the validity of proximity as an estimate for environmental health hazard exposure, and suggests how it may be used as an indicator in future environmental health and justice research. Using geostatistics and geographic information systems, air pollution monitoring data in Hamilton, Canada are interpolated to obtain local estimates of total suspended particulates. These estimate...

Many papers discuss the voltage stability assessment of power system using power flow analysis methods. In this paper, a method for online monitoring of a power system based on measurements is proposed, which is aimed at detection of the voltage instability. Thereby an indicator is derived from the fundamental Kirchoff-Laws. Since in the transient process, at any time point, the electric power ...
