The determination of the weight distribution linear codes has been a fascinating problem since very beginning coding theory. There lot research on enumerators special cases, such as self-dual and with small Singleton's defect. We propose new set relations that must be satisfied by coefficients distribution. From these we are able to derive known identities (in an easier way) for interesting ext...

this qualitative study has been done with the final objective of exploring the in-crisis firms’ turnaround process, using a systematic plan of grounded theory. so, open 10 interviews were conducted exclusively with managers of listed (accepted) companies’ in tehran stock exchange experiencing financial crisis during 2006-2012 and they have been successful in turnaround. the results of analysis ...

This article provides a tutorial overview of cognitive architectures that can form a theoretical foundation for designing multimedia instruction. Cognitive architectures include a description of memory stores, memory codes, and cognitive operations. Architectures that are relevant to multimedia learning include Paivio’s dual coding theory, Baddeley’s working memory model, Engelkamp’s multimodal...

Generation of optimal codes is a well known problem in coding theory. Many computational approaches exist in the literature for finding record breaking codes. However generating codes with long lengths n using serial algorithms is computationally very expensive, for example the worst case time complexity of a Greedy algorithm is O(n 4). In order to improve the efficiency of generating codes wit...

According to the matter of knowledge-based businesses development in economic development and job creation of the state, it is so important to identify effective strategies and factors in developing entrepreneurship, supporting commercializing and branding of knowledge-based businesses and the environment in which these businesses fare formed. The purpose of the present research is offering an ...

in this paper, we investigate duality of modular g-riesz bases and g-riesz basesin hilbert c*-modules. first we give some characterization of g-riesz bases in hilbert c*-modules, by using properties of operator theory. next, we characterize the duals of a giveng-riesz basis in hilbert c*-module. in addition, we obtain sucient and necessary conditionfor a dual of a g-riesz basis to be again a g...
