The notion of genre has received a great deal of attention both in discourse analytic studies as well as in the field of ESP/EAP course design. The present paper has attempted to use genre analysis to account for the rhetorical features of research article introductions written by Iranian academics in two disciplinary fields of Education and Economics. The corpus comprised 40 research article i...

In this paper, we investigate whether incorporating common factors of CPI sub-aggregates into forecasting models increases the accuracy of forecasts of inflation. We extract factors by both static and dynamic factor models and then embed them in ARMA and VAR models. Using quarterly data of Iran’s CPI and its sub-aggregates, the models are estimated over 1990:2 to 2008:2 and out of sample ...

In configuration design, the task is to compose a system out of set predefined, modu-lar building blocks assembled by defined interfaces. Product systems, both with or without integration geometric models, implement reasoning techniques model and explore resulting solution spaces. Among others, formulation constraint satisfaction problems (CSP) state art informational background in many proprie...

The list update problem is studied in a distributed environment where the set of items is partitioned across two processors and in which the cost of accessing an item is a combination of a list searching cost and a communication cost. A natural generalization of the Move-To-Front (MTF) algorithm, called Distributed Move-To-Front (DMTF), is analyzed under two models of information available to t...

for the analysis of structures, the first step consists of configuration processing followed by data generation. this step is the most time consuming part of the analysis for large-scale structures. in this paper new graph products called triangular and circular graph products are developed for the formation of the space structures. the graph products are extensively used in graph theory and co...

the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycyc...

introduction: with using multiple linear regression (mlr), can simultaneously analyses several different variables, but to get the desirable results from the mlr, the samples must be much and accurate. therefore, this method has high sensitivity and may cause errors in results. in addition, to use this method, the variable must have normal distribution and modification follow from a linear rela...
