this paper defines how a meta heuristic search engine called p.s.o can be used to maximize the objective function of a logistic regression model, describing the relationship between the response variable (product designs' score) and a set of explanatory variables (product design factors). at the first phase the processed data, classified and categorized, by kansie engineering is used as input t...

computer-integrated manufacturing (cim), technologies are presented as solutions tomanufacturing organizations, which need to perform well in all customer-related dimensionssimultaneously. in the literature, cim technologies providing such benefits as more frequentproduction changes, reduced inventory level, improved ability of producing complex parts with ahigh degree of accuracy and repeatabi...

all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

this paper presents a detailed small-signal and transient analysis of a full bridge pwm dc-dc converter designed for high voltage, high power applications using an average model. the derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. results obtained in the analysis of the high voltage and high power design examp...

pavement permanent deformations due to lack of shear strength in mixture are a major reason of rutting. any simple test to determine mixtures resistance to permanent deformation isn’t distinguished in the 1st level of superpave mix design method and prevalent methods for evaluating mixture rut resistance are expensive and time-consuming. two aggregate types, gradations, asphalt cements and fill...

new product development (npd) is one of the key factors for achieving competitive advantage and maintaining firm growth. therefore, given the importance of this type of projects, this paper is an endeavor to make these projects more successful by effectively managing their risks in the conceptual design phase of new product development. for this purpose, a multi-objective model, with three obje...
