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 ...
Random Access Memory is major component in present day SOC, by Improving the yield of RAM improves the yield of SOC. So the repairable memories play a vital role in improving the yield of chip. Built-in self-repair (BISR) technique has been widely used to repair embedded random access memories (Ram's). If each repairable RAM uses one self contained BISR circuit (Dedicated BISR scheme), then the...
In this paper, a new class of Public-Key Cryptosystem (PKC) based on Random Simultaneous Equation of degree g(RSE(g)PKC) is presented. The proposed scheme uses a new class of trap-doors based on two classes of transformation, i.e. random transformation and message-dependent random transformation. For constructing the proposed scheme, random transformations X and Ψ are used. The transformation Ψ...
This study was conducted to compare three models: two random regression models with and without considering heterogeneity in the residual variances and a lactation model (LM) for evaluating the genetic ability of Holstein cows in Korea. Two datasets were prepared for this study. To apply the test-day random regression model, 94,390 test-day records were prepared from 15,263 cows. The second dat...
We construct a model of referral hiring to examine the effects of social network structure on group level inequality. Our study departs from many studies of social networks and labor market outcomes in that we focus on groups and not on individuals. We find that more random social networks yield higher employment rates than less random social networks if the population is integrated or informat...
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...
to investigate the effects of methyl jasmonate growth regulators on growth characteristics, fruit number and fruit yield of ‘semsuri’ melon, an experiment at the field of shahid bahonar university was conducted in summer 2012. melon (cv. ‘semsuri’) is widely cultivated in iran and therefore increasing the fruit yield and quality of this cultivar is necessary. some growth regulators including me...
the objective of the present study was to estimate genetic trends for lactation milk yield, persistency of milk yield, somatic cell count and interval between first and second calving in holstein dairy cows of iran. the dataset consisted of 210,625 test day and 25,883 first parity cows with milk yield recorded from july 2002 to september 2007 comprising 97 herds in iran. breeding values of anim...
in order to investigate the yield stability of eight promising rice genotypes, these lines along with shiroudi and fajr cultivars as control were sown in three regions of mazandaran province (amol, sari and tonekabon) as randomized complete block arrangements with three replications in 2012 and 2013. analysis of variance for grain yield indicated significant differences among the genotypes in a...
