in urmia county, irrigated wheat yield varies in different regions. the highest and lowest yields are attributed to nazloo region (6.58 tons per hectare) and the lowest yield was for silvana region ( 2.77 tons per hectare) respectively. so, the purpose of this study is analysis of management factors impact on irrigated wheat yield in nazloo and silvana regions of urmia county. to this end, by q...

The literature under random component yield has focused on coordination of supply chain at the determined price, where decision maker chooses its optimal production quantities. The authors consider a centralized system when the price is not determined under both random yield and demand. Type A with perfect quality and type B with imperfect quality are produced due to the random yield. They prov...

Many entanglement distillation schemes use either universal random hashing or breading as their final step to obtain shared almost perfect EPR pairs. Both methods involve random stabilizer quantum error-correcting codes whose syndromes can be measured using simple and efficient quantum circuits. When applied to high fidelity Werner states, the highest yield protocol among those using local Bell...

Parachute transplanting method of rice as compared to line transplanting and farmer’s method of random transplanting was studied at 10 different locations viz., Kamonki, Wazirabad, Daska, Pasroor, Gujranwala, Sialkot, Lahore, Hafizabad and Sheikhupura during 2003 and 2004. Super Basmati was used as test variety. Yield and yield components of three transplanting techniques, averaged across 10 lo...

For a bivariate random vector (X, Y ), symmetry conditions are presented that yield stochastic orderings among |X|, |Y |, |max(X, Y )|, and |min(X, Y )|. Partial extensions of these results for multivariate random vectors (X1, ..., Xn) are also given.

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...

Much effort has been devoted to the synthesis of gold nanoparticles with different shapes, including the zero-dimensional nanospheres, one dimensional nanorods, and two-dimensional nanoplates. Compared to zero or one dimensional nanostructures, the synthesis of two-dimensional nanostructures in high yield has always been more involved, often requiring complex and timeconsuming steps such as mor...

The distribution of linear combinations of independent chi-square random variables is intimately related with the distribution of quadratic forms in normal random variables [1, 6, 7, 8, 9, 10, 11, 13, 14] and thus it also appears as the limit distribution of quadratic forms in non-normal random variables. As such, this distribution has been studied by many authors [2, 4, 5, 6, 7, 8, 9, 10, 11, ...
