One of the most important aspects of software project management is the estimation of cost and time required for running information system. Therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. Software cost estimation refers to the process of development requirement prediction of software system. Various kinds of effort estimation patter...

Machine learning research, particularly in genomics, is often based on wide shaped datasets, i.e. datasets having a large number of features, but small samples. Such configurations raise the possibility chance influence (the increase measured accuracy due to correlations) process and evaluation results. Prior research underlined problem generalization models obtained such data. In this paper, w...

the purpose of this study was to evaluate three models of artificial neural networks (ann), regression trees (m5) and hargrives-samani (hg) in estimation of reference evapotranspiration. for this purpose was used climate information of sistan va baloochestan, kerman, yazd and khorasan jonoobi from 1998 to 2008. in addition to effect of wind (u) on evapotranspiration (et0), estimation of et0 was...

This paper describes a formal model for the recognition of on-line handwritten mathematical expressions using 2D stochastic context-free grammars and hidden Markov models. Hidden Markov models are used to recognize mathematical symbols, and a stochastic context-free grammar is used to model the relation between these symbols. This formal model makes possible to use classic algorithms for parsin...

The censored regression model and the Tobit model are standard tools in econometrics. This paper provides a formal asymptotic theory for dynamic time series censored regression when lags of the dependent variable have been included among the regressors. We derive fading memory properties of the model under the assumption that the regression error is strong mixing. We show the formal asymptotic ...

In this paper we describe a mechanism to improve Information Retrieval (IR) on the web. The method is based on Formal Concepts Analysis (FCA) that it is makes semantical relations during the queries, and allows a reorganizing, in the shape of a lattice of concepts, the answers provided by a search engine. We proposed for the IR an incremental algorithm based on Galois lattice. This algorithm al...

This paper considers the problem of informative path planning under temporal logic (TL) correctness constraints. For example, a robot deployed to a building after a natural disaster must explore the area and report possible locations of survivors with minimum uncertainty. The robot must satisfy the correctness requirement “Always avoid obstacles. Report data to rescuers at a data upload hub bef...

The need for improved implementation of information technology (IT) strategy has been emphasised in both empirical and prescriptive research studies. In this study, the main research question is: “What content characteristics of formal IT strategy predict the extent of plan implementation?”. Ten content characteristics of formal information technology strategy were identified from the research ...

Self-managing systems will be highly dependent upon information acquired from disparate applications, devices, components and subsystems. To be effectively managed, such information will need to conform to a common model. One standard that provides a common model for describing disparate computer and network information is the Common Information Model (CIM). Although CIM defines the models nece...
