This paper proposes a genetic weighted K-means algorithm called GWKMA, which is a hybridization of a genetic algorithm (GA) and a weighted K-means algorithm (WKMA). GWKMA encodes each individual by a partitioning table which uniquely determines a clustering, and employs three genetic operators (selection, crossover, mutation) and a WKMA operator. The superiority of the GWKMA over the WKMA and o...

Smith and Osherson proposed the prototype view for concept representation and category cls, Hiflcafion. In the prototype view, concepts are represented as prototypes. A prototype is a collection of salient properties of a conceptUnder the prototype view, a~ instance is classified as a memberofa concept ifit is sufficiently similar to the prototype of this concept. Although the prototype view ha...

Background: Polycystic ovarian syndrome (PCOS) is a medical condition that affects women's menstrual cycles, fertility, hormone levels, and physical appearance. PCOS is thought to be one of the leading causes of female infertility, and is the reason of more than 75% of cases of anovulatory infertility. Materials and Methods: In this article, we review the different aspects of PCOS includin...

vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. this paper presents a bi-objective mathematical mod...

BACKGROUND Obesity is a major risk factor for dyslipidemia, but this relationship is highly variable. Recently published data from 2 Danish cohorts suggest that genetic factors may underlie some of this variability. METHODS AND RESULTS We tested whether established triglyceride-associated loci modify the relationship of body mass index (BMI) and triglyceride concentrations in 2 Swedish cohort...

In this study test-day records of milk (kg), fat (g), and protein (g) yields, somatic cell score (SCS, cells/ML) collected by Animal Breeding Center of Iran during 2007 and 2009 were used to estimate genetic parameters using random regression model. Models with different order of Legendre polynomials were compared using Bayesian information criterion (BIC).For milk, fat yield and SCS genetic an...
