The aim of this study was to geographically analyse the traffic casualties in pedestrians in downtown of Tehran City. Study population consisted of pedestrians who had traffic injury accidents from April 2014 to March 2015 in Tehran City. Data were extracted from the offices of traffic police and municipality. For analysis of environmental factors and site of accidents, Ordinary Least Square (O...

This paper introduces a mixed method approach for analyzing the determinants of natural latex yields and the associated spatial variations and identifying the most suitable regions for producing latex. Geographically Weighted Regressions (GWR) and Iterative Self-Organizing Data Analysis Technique (ISODATA) are jointly applied to the georeferenced data points collected from the rubber plantation...

This work aims to analyse different design proposals for a dynamic Weighted Fair Queuing (WFQ) scheduler to provide Quality of Service (QoS) guarantees in general at IP level and specifically for the applications of the PHOENIX project. Several possible design options and configuration parameters have been investigated and studied for a dynamic scheduling discipline able to support QoS in a rel...

Monte Carlo simulation is used to obtain estimates of the probability that all weighted scoring rules elect the same winner for large electorates under the impartial culture condition. While this probability is relatively large for three candidate elections (0.535), it decreases significantly as the number of candidates increases. The same general observations are made when considering the prob...

in this note we characterize the compact weighted frobenius-perron operator $p$ on $l^1(sigma)$ and determine their spectra. we also show that every weakly compact weighted frobenius-perron operator on $l^1(sigma)$ is compact.

In automata theory, Büchi’s and Elgot’s fundamental theorems [6, 7, 25] established the coincidence of regular and ω-regular languages with languages definable in monadic second-order logic. At the same time, Schützenberger [57] investigated finite automata with weights and characterized their behaviours as rational formal power series. Both of these results have inspired a wealth of extensions...

the aim of this study is quantity determining and evaluating of the quality position of teaching and learningprocess. so, the artificial neural networks were used for modeling nonlinear relationships to inspect and evaluate different models of service quality evaluation. the statistical population include 1070 peoples, which were master and phd students of faculty of agriculture of ferdowsiuniv...
