Taking intuitionistic fuzzy sets as the structures of truth values, we propose the notions of intuitionistic fuzzy context-free grammars (IFCFGs, for short) and pushdown automata with final states (IFPDAs). Then we investigate algebraic characterization of intuitionistic fuzzy recognizable languages including decomposition form and representation theorem. By introducing the generalized subset c...

CDK5RAP2 is one of the primary microcephaly genes that are associated with reduced brain size and mental retardation. We have previously shown that human CDK5RAP2 exists as a full-length form (hCDK5RAP2) or an alternatively spliced variant form (hCDK5RAP2-V1) that is lacking exon 32. The equivalent of hCDK5RAP2-V1 has been reported in rat and mouse but the presence of full-length equivalent hCD...

This paper is concerned with the problem of finding a reduced form of a linear discrete system with noisy observations, where the reduced form of the system is a system with minimum dimensional state space which is equivalent to the given system. For systems initially in their zero states, two systems are defined to be equivalent in the sense that the responses of these systems to the same inpu...

intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

a study on the evaluating equivalent damping and response modification factors of frames equipped by pall friction dampers is presented. to do so, buildings with various stories were considered. nonlinear and linear dynamic time history analysis has been performed to evaluate equivalent damping for pall friction dampers. ground motions with various frequency characteristics scaled with iranian ...

The theoretical foundations of linear circuit theory rest on Maxwell’s theory of electromagnetism. In its more applied form, circuit theory rests on the key concepts of Kirchoff’s Laws, impedance, Ohm’s Law (in its most general sense by encompassing impedances), and the Principle of Superposition. From this foundation, any linear circuit can be solved: given a specification of all sources in th...

Abstract We examine the effects of postulated metric on measurement well-being, by comparing, in (income, lifetime) space, two indexes: equivalent income index and lifetime index. The conditions under which exists are more restrictive than ones exists, but it is possible to define an alternative index, based reference levels, for non-existence problem less acute. Those indexes also shown satisf...
