Designers draw diagrams to think about architectural concepts and design concerns. Scientists are interested in programming computers to recognize and interpret design diagrams to deliver appropriate tools for the design task at hand. Researchers conducted empirical studies to find out if designers share drawing conventions when designing. The experiment results show that designers use differen...
in (golchin a. and rezaei p., subpullbacks and flatness properties of s-posets. comm. algebra. 37: 1995-2007 (2009)) study was initiated of flatness properties of right -posets over a pomonoid that can be described by surjectivity of corresponding to certain (sub)pullback diagrams and new properties such as and were discovered. in this article first of all we describe po-flatness propertie...
this paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and petri nets. in the beginning, programmable logic controllers were widely designed by ladder logic diagrams. when complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. thus, petri nets as a high l...
uml is known as one of the most common methods in software engineering.since this language is semi-formal, many researches and efforts have beenperformed to transform this language into formal methods including petri nets.thus, the operation of verification and validation of the qualitative and nonfunctionalparameters could be achieved with more ability. since the majority of thereal world info...
graham higman has defined coset diagrams for psl(2,ℤ). these diagrams are composed of fragments, and the fragments are further composed of two or more circuits. q. mushtaq has proved in 1983 that existence of a certain fragment γ of a coset diagram in a coset diagram is a polynomial f in ℤ[z]. higman has conjectured that, the polynomials related to the fragments are monic and for a fixed degree...
