increasing non-oil exporting is among the most important concerns for iran. software industry is among the knowledge based and profitable ones. identification of factors affecting export performance of software developers can improve planning that in turn results in increasing software export. in this research a model consisting of seven important variables in software industries including: com...

The equivalence between autonomicity and the absence of free variables is a well-known result for linear, shift-invariant and complete behaviors over a field. However, this no longer holds for a behavior that does not satisfy one of those properties. In this paper we consider linear, shift-invariant and complete behaviors over the ring Zpr and study under which conditions such behaviors are aut...

This paper presents an analysis of the copy construction that explains its similarity to extraction constructions while accounting for its incompatibility with wh+NP phrases. Essentially, wh-phrases without an NP complement can be copied because they’re non-quantificational (introducing only a free variable into the derivation). Whphraseswith anNP complement cannot be copied because thesewh-phr...

Field equations for generalized principle models with nonconstant metric are derived and ansatz for their Lax pairs is given. Equations that define the Lax pairs are solved for the simplest solvable group. The solution is dependent on one free variable that can serve as the spectral parameter. Painlevé analysis of the resulting model is performed and its particular solutions are found 1991 MSC ...

The present paper examines the dynamics between macroeconomic variables and stock market. index of industrial production, inflation, gold price, oil return from treasury bills have been used as proxy variables. Indian market has typified by Sensex. Monthly observations analyzed April 1993 to October 2022 through cointegration Granger causality test examine possible long-run short-run relationsh...

A set of operat ions for construct ing a lgebra ic specif icat ions in an arbi t rary logical system is presented. This builds on the f ramework provided by Goguen and Burstal l 's work on the not ion of an inst i tut ion as a formal isat ion of the concept of a logical system for wri t ing specif icat ions. We show how to introduce free variables into the sentences of an arbi t rary institutio...

An important feature of speech-gesture integration is that speech and gesture content influence each other in interpretation. To analyse this, we sketch an approach based on three assumptions: (i) the interpreter infers by abduction an explanation for why a particular gesture is synchronized with a particular utterance (part), (ii) semantic composition amounts to the identification of free vari...
