The objective of this study was to estimate variance components and genetic parameters for growth curve parameters in Shall sheep. Studied traits were parameters of Brody growth model which included A (asymptotic mature weight), B (initial animal weight) and K (maturation rate). The data set and pedigree information used in this study were obtained from the Animal Breeding Center of Iran and co...

In this paper, we consider a flow shop scheduling problem with availability constraints (FSSPAC) for the objective of minimizing the makespan. In such a problem, machines are not continuously available for processing jobs due to preventive maintenance activities. We proposed a mixed-integer linear programming (MILP) model for this problem which can generate non-permutation schedules. Furthermor...

Nowadays, with extending applications of bi-layer metallic sheets in different industrial sectors, accurate specification of each layer is very prominent to achieve desired properties. In order to predict behavior of sheets under different forming modes and determining rupture limit and necking, the concept of Forming Limit Diagram (FLD) is used. Optimization problem with objective functions an...

Conventional SOI DNAFET devices, being able to detect single-nucleotide polymorphisms, are simulated in a comprehensive approach. These devices can be fabricated in high-density arrays and offer advantages compared to optical detection methods. The influence of device parameters like doping concentration and the size of the exposed sensor area is investigated.

A closed 6R linkage is generically rigid. In this paper we give, for the first time, equational conditions on the Denavit/Hartenberg parameters that are necessary for mobility. The conditions suggest to distinguish the movable 6R linkages into various types characterized by their bond diagrams.

objective: estimation of genetic parameters for kleiber ratio (kr) and genetic trends for pre-weaning weights of arabi sheep has not been previously conducted.methods: data and pedigree information were collected at the khuzestan ramin agricultural and natural resources university, animal science research station, located in southwest iran, from 2001 to 2008. (co)variance components and corresp...

conclusions the results of the present study showed that tgf-β1 (-509) c/t is strongly associated with quantitative parameters of connective tissue constituents of interdental papilla in cp patients. results the volume density (vʋ) of epithelium, connective tissue, collagenous and non-collagenous matrix and blood vessels had statistically significant differences between the control and chronic ...

Fermentation processes are characterized with non-linear and time-dependent parameters that make their parameter identification non-trivial task. Failure of conventional optimization methods to yield a satisfactory solution provokes the idea for some stochastic algorithms to be applied. As such, different modifications of simple genetic algorithms (SGA) have been investigated aiming to improve ...
