The homogenized elastic properties of polycrystals depend on the grain morphology and crystallographic orientations. For simplification purposes, orientations grains are usually considered three independent Euler angles. However, experimental investigations reveal spatial correlations in these Karhunen–Loève expansion is used to generate random fields angles having exponential kernel functions ...

We show that the pseudoeffective cone of divisors $\overline{\text{Eff}}^1(\overline{\mathcal{M}}_{g,n})$ for $g\geq 2$ and $n\geq is not polyhedral by showing class fibre morphism forgetting one point forms an extremal ray dual nef curves $\overline{\text{Nef}}_1(\overline{\mathcal{M}}_{g,n})$ at this polyhedral.

Residue Number System (RNS) is a carry-free and non-weighed integer system. In this paper an improved three-moduli set  in reverse converter based on CRT algorithm is proposed. CRT algorithm can perform a better delay and hardware implementation in modules via other algorithms. This moduli is based on p that covers a wide range on modules and supports the whole range of its modules in dynamic r...

The dependence relation between the macroscopic effective property and the microstructure of interpenetrating multiphase composites is investigated in this paper. The effective elastic moduli of such composites cannot be calculated from conventional micromechanics methods based on Eshelby s tensor because an interpenetrating phase cannot be extracted as dispersed inclusions. Employing the conce...

Motivated by interest in the elastic properties of high-strength amorphous metals, we examine the elastic properties of select crystalline phases. Using first-principles methods, we calculate elastic moduli in various chemical systems containing transition metals, specifically early (Ta,W) and late (Co,Ni). Theoretically predicted alloy elastic properties are verified for Ni-Ta by comparison wi...

The pseudo-effective cone Eff(X) of a smooth projective variety X is a fundamental, yet elusive invariant. On one hand, a few general facts are known: the interior of the effective cone is the cone of big divisors so, in particular, X is of general type if and only if KX ∈ int(Eff(X)); less obviously [4], a variety X is uniruled if and only if KX is not pseudo-effective and the dual of Eff(X) i...
