In-plane uniaxial tension of AZ31 magnesium alloy sheet with non-basal texture has been conducted in order to demonstrate the effects loading direction on microstructure evolution and mechanical properties at ambient temperature. Loading axes are chosen be along five directions distributed between rolling (RD) transverse (TD), allowing various activities involved slip twinning modes take place....

Many video coding schemes, including MPEG-2, use a Discrete Cosine Transform (DCT). The recently completed video coding standard, H.264/AVC, uses an integer transform, which will be referred to as HT in this paper. We propose an ecient method to convert DCT coefficients to HT coeffients entirely in the transform domain. We show that the conversion is essentially a 2D transform.We derive the tra...

The logit and probit models are critical parts of the management researcher's analytical arsenal. We often want to know if a covariate has the same effect for different groups, e.g., foreign and domestic firms. Unfortunately, many attempts to compare the effect of covariates across groups make the unwarranted assumption that each group has the same residual variation. If this is not the case, c...

In this paper, we consider translation and multiplication operators acting on the rings of symmetric and nonsymmetric polynomials and study their matrix coefficients with respect to the bases of Jack polynomials and interpolation polynomials. The main new insight is that the symmetric and nonsymmetric cases share a key combinatorial feature, that of a locally finite graded poset with a minimum ...

The forming limit diagram (FLD) is a widely used tool to assess the formability of metal sheet [1]. current study aims investigate influence strain rate, material anisotropy and hardening on FLD Ti-6Al-4V predicted by well-known Marciniak-Kuczynski (M-K) method. tensile data quasi-static (8 10 -5 s -1 ), intermediate (0.5 ) dynamic experiments (approximately 1000 are available at three differen...

We give a new interpretation of the shifted Littlewood-Richardson coefficients $f_{\lambda\mu}^\nu$ ($\lambda,\mu,\nu$ are strict partitions). The $g_{\lambda\mu}$ which appear in decomposition Schur $Q$-function $Q_\lambda$ into sum functions $Q_\lambda = 2^{l(\lambda)}\sum_{\mu}g_{\lambda\mu}s_\mu$ can be considered as special case (here $\lambda$ is partition length $l(\lambda)$). also anoth...

rapeseed (brassica napus l.) is a crop relatively tolerant to salt. the effect of different ratios of nacl/kcl was studied in two cultivars (hyola308 and kristina) of rapeseed in 2002. canola seedlings were grown in hoagland’s solutions, which were salinized by different ratios of nacl/kcl. the treatments or kcl:nacl ratios were 0:0 (control);10:10; 20:0 (total added salt or tas=20 mol.m-3), 0:...
