By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus, every permutation matrix over C is a quasipermutation matrix. For a given finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G (or of a faithful representation of G by permutation matrices), let q(G) denote the minimal degree of a fa...

‎‎in cite{fr 1‎, ‎fr 2} using faithful complex representations of cyclically pinched and conjugacy pinched one-relator groups we proved that any limit group has a faithful representation in $psl(2,c)$‎. ‎further this representation can be effectively constructed using the jsj decomposition‎. ‎in this note we show that any hyperbolic cyclically pinched one-relator group with maximal amalgamated ...

Abstract Through the interpretation of texts, and subsequent creation of social reality, mediated representations are often seen to be presented within the certain of ideological discourses that reflect the existing power structures. The main objective of this paper is to analyze television commercials with an emphasis on gender roles to decode the main elements of a dominant discourse (prefer...

Owing to the growing interest in communicative, cultural and pragmatic aspects of second language learning in recent years, the present study tried to investigate representations of pragmatic aspects of English as a foreign language in Iranian high school textbooks. Using Halliday’s (1978), and Searle’s (1976) models, different language functions and speech acts were specifically determined and...

In this paper, a new method is introduced for improving the efficiency of the Residue Number System, which uses both binary and residue representations in order to represent a number. A residue number system uses the remainder of the division in several different modules. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...
