A rectangular rod is placed in a flow field flowing parallel to a flat plate. Effect of chord-thickness ratio of rectangular rod on developing vortex shedding downstream to the rod is studied. Then, for each one of the aspect ratios, the distance of the rod from the neighboring flat plate is reduced until the rod sticks to the flat plate. In each case, the effect of the flat plate boundary laye...

We construct a Kähler structure (J,Ω, G) on the space L(H) of oriented geodesics of hyperbolic 3-space H and investigate its properties. We prove that (L(H), J) is biholomorphic to P×P−∆, where ∆ is the reflected diagonal, and that the Kähler metric G is of neutral signature, conformally flat and scalar flat. We establish that the identity component of the isometry group of the metric G on L(H)...

dually flat finsler metrics form a special and valuable class of finsler metrics in finsler information geometry,which play a very important role in studying flat finsler information structure. in this paper, we prove that everylocally dually flat generalized randers metric with isotropic s-curvature is locally minkowskian.

let r be a commutative noetherian ring. we study the behavior of injectiveand at dimension of r-modules under the functors homr(-,-) and -×r-.

These notes aim at providing a complete and systematic account of some foundational aspects algebraic supergeometry, namely, the extension to geometry superschemes many classical notions, techniques results that make up general backbone geometry, most them originating from Grothendieck's work. In particular, we extend supergeometry such notions as projective proper morphisms, finiteness cohomol...

This paper presents the results of the analysis of 56,000 flat grids in a form suitable for minimum weight design.

We introduce the notion of strongly ω -Gorenstein modules, where ω is a faithfully balanced self-orthogonal module. This gives a common generalization of both Gorenstein projective (injective) modules and ω-Gorenstein modules. We investigate some characterizations of strongly ω -Gorenstein modules. Consequently, some properties under change of rings are obtained. Keywords—faithfully balanced se...

Flat rate regime is held responsible for this state of affairs and a shift to universal metering is being pushed as remedy. However, metering can work only by creating power retailing entrepreneurs as is being tried out in Orissa. Flat tariff regime can also serve the purpose, provided it is tied to effective supply policies. Judicious rationing and reasonable tariff are essential components of...

We propose a protocol Dn for faithfully teleporting an arbitrary n-qudit state with the tensor product state (TPS) of n generalized Bell states (GBSs) as the quantum channel. We also put forward explicit protocol D′ n and D′′ n for faithfully teleporting an arbitrary n-qudit state with two classes of 2n-qudit GESs as the quantum channel, where the GESs are a kind of genuine entangled states we ...
