With certain conditions for target-samples and beams, we have identified specific particles (e.g., 4.75MeV tritons and He-particles, and 15.9 MeV deuterons) from 3D fusion reactions with yield ratios [3D]/[2D] on the order of 1E-4 to 1E-3, in contrary to the calculated [3D]/[2D] yield ratio of 1E-30 according to conventional random nuclear reaction theory. The increasing trend of yield ratios i...

We study numerically a simple network model which is an electrical analog of a perfectly plastic disordered medium. For a uniform random distribution of local maximum current, (e.g. yield stress), we study the evolution of the properties of the system as a function of the number of elements which reached the plastic limit. It is shown that the macroscopic yield point can be interpreted as a cri...

A random process corresponding to an autonomous oscillator with random parameters depends on the choice of a phase condition is considered. An appropriate quantification of uncerntainties is achieved by a random process with a minimal total variance. The authors has shown a necessary condition for an optimal solution using the calculus of variations. A corresponding numerical method has been co...

We address the problem of computing critical area for open faults in a circuit layout in the presence of multilayer loops and redundant interconnects. The extraction of critical area is a fundamental problem in VLSI yield prediction. We first model the problem as a graph problem and then we solve it efficiently by exploiting its geometric nature. We introduce the open-fault Voronoi diagram of p...

Research on test day (TD) models began in Canada in 1991. At that time fixed regressions (within age and season of calving) were used to account for the shape of the lactation curve of dairy cows, but the animal effect was used only to account for differences in height of these curves (Ptak and Schaeffer, 1993). Fixed regression TD model was applied to Canadian dairy goat data (Schaeffer and Su...

Variace / covariance components of 227118 first lactaiom test-day milk yield records belonged to 31258 Iranian Holstein cows were estimated using nine random regression models. Afterwards, different measures of persistency based on estimation breeding value were evaluated. Three functions were used to adjust fixed lactation curve: Ali and Schaeffer (AS), quadratic (LE3) and cubic (LE4) order of...

I this study, we investigate the effects of recovery yield rate on pricing decisions in reverse supply chains. Motivated by the automotive parts remanufacturing industry, we consider an end-of-life product from which a particular part can be recovered and remanufactured for reuse, and the remainder of the product can be recycled for material recovery. Both the supply of end-of-life products and...

This paper investigates the effects of wheat production risk and other socio-economic factors on the probability of adopting new seed technologies. Also, the effects of production inputs and production conditions are examined on wheat production yield and risk. Moreover, the relative risk of new seed varieties will be examined under different scenarios. To carry out the study, farm-level data ...

Dairy cattle breeding programs have been based in the selection for traits related to milk production. In this research a data set of 63 herds of East Azerbaijan province Holstein cattle, collected during 2002-2013 by the Iranian Animal Breeding Center was used to estimate the repeatability and heritability of three traits of economic importance. Genetic parameters for first three lactations of...

This study was undertaken to estimate genetic trend and parameters of Holstein cattle in Khorasan province for milk yield using a spline random regression test day animal model. A total of 32854 monthly test day milk records (twice and thrice a day milking) obtained from 3842 Holstein heifers (progeny of 466 sires) distributed in 125 herds and calved from 2001 to 2005 was used to predict breedi...
