Adaptive optics (AO) systems using tomographic estimation of three-dimensional structure atmospheric turbulence requires vertical profile, which describes strength as a function altitude prior information. We propose novel method to reconstruct the profile by applying Multi Aperture Scintillation Sensor (MASS) scintillation data obtained Shack-Hartmann wavefront sensor (SH-WFS). Compared tradit...

Purpose. To indentify the best shallot cultivars and local forms by growing period length, bulb yield, leaf productivity, weight number per clump in Right-Bank Forest-Steppe of Ukraine. Methods. Statistical processing, field assessments, computational analytical methods. Results. Collection accessions were evaluated for lengthand, weight, performance. Earlyripening accession ‘Sh-8’ with a veget...

Suppose we are given a family of choice functions on pairs from a given finite set (with at least three elements) closed under permutations of the given set. The set is considered the set of alternatives (say candidates for an office). The question is, what are the choice functions c on pairs of this set of the following form: for some (finite) family of “voters”, each having a preference, i.e....

Abstract The electromagnetic (EM) field variations capable of probing the electrical conductivity upper mantle and transition zone have a period range between few hours 1 day. At these periods, dominant source EM signals is ionospheric current system, which has complex spatial temporal structure. A concept global-to-local (G2L) transfer functions can handle spatially by relating global expansio...

The existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. Thus, wave propagations through a corrugated interface are so important. In this paper, a two-dimensional SH-wave propagation through a corrug...

Background: In nuclear medicine application often it is required to use computational methods for evaluation of organ absorbed dose. Monte Carlo simulation and phantoms have been used in many works before. The shape, size and volume in organs are varied, and this variation will produce error in dose calculation if no correction is applied. Materials and Methods: A computational framewo...

Two main controlling factors of ice crystal growth are the heat and (gaseous) mass transfers, H&MT, as characterized by the Nusselt number (Nu) for heat and the Sherwood (Sh) number for mass. Nu and Sh express the increase of the molecular diffusions by the relative motions of the particles in air as characterized by the Reynolds number (Re). Traditionally Nu is assumed to be identical to Sh. P...

Aims. We apply Floquet analysis to study the dynamical stability of two-dimensional axisymmetric Keplerian flows distorted by an m = 2 epicyclic periodic forcing term, representing a tidal perturbation in a thin accretion disk (AD) of a cataclysmic variable (CV). This tidal mode is responsible for the disk truncation mechanism. Methods. Floquet analysis reveals, with a positive Floquet exponent...

OVERVIEW: Sega Enterprises, Ltd. announced its next-generation highperformance entertainment console Dreamcast*1 at a press conference on July 20, 1998 and won widespread acclaim during the demonstration of its powerful and precise video images. Dreamcast’s nucleus is Hitachi, Ltd.’s SH-4 microprocessor. SH-4 is the top-of-the-line model in Hitachi’s highperformance SuperH series reduced instru...

The Riesz potential f s ( r ) = − $f_s(r)=r^{-s}$ is known to be an important building block of many interactions, including Lennard-Jones–type potentials n , m LJ : a b $f_{n,m}^{\rm {LJ}}(r):=a r^{-n}-b r^{-m}$ > $n>m$ that are widely used in molecular simulations. In this paper, we investigate analytically and numerically the minimizers among three-dimensional lattices Lennard-Jones energies...
