purpose: the aim of present study was the comparative evaluation of content and support quality of iranian academic libraries websites’ and provide recommendations to improve them.methodology: this study is an applied research and methodology was comparative survey. data gathering tools were three checklists extracted from relevant studies which compare with 5 foreign library websites, and thei...

the present research was to comparative study of relationship emotional intelligence to mental health and academic achievement in shahed and non shahed student.in order to conduct the research 300 students (150 shahed and 150 non shahed) under graduate students or in tehran university were randomly selected. to gather data 33 items sherink's ei questionnaire were used. twenty eight items g...

There is a well known necessity to extract knowledge from spatial databases. Dozens of algorithms for data mining and knowledge discovery are reported in the specific literature to supply this necessity. However, these algorithms have some general drawbacks. Some consider only spatial data and others, only non-spatial data. Most are pseudo-codes, which are usually not implemented in toolkits, a...

In this paper, simple autonomous chaotic circuits coupled by resistors are investigated. By carrying out computer calculations and circuit experiments, irregular self-switching phenomenon of three spatial patterns characterized by the phase states of quasi-synchronization of chaos can be observed from only four simple chaotic circuits. This is the same phenomenon as chaotic wandering of spatial...

 Spatial generalized linear mixed models are used commonly for modelling non-Gaussian discrete spatial responses. We present an algorithm for parameter estimation of the models using Laplace approximation of likelihood function. In these models, the spatial correlation structure of data is carried out by random effects or latent variables. In most spatial analysis, it is assumed that rando...
