Perceived organization of hierarchically constructed patterns was investigated through similarity judgments and a verbal description task. The number of elements and their sizes relative to the configuration were varied in a series of five experiments. The results show that in patterns composed of a few relatively large elements, the elements are perceived as individual parts of the overall for...

In this paper, we take up the question of dynamic stability of genuinely two-dimensional ‘‘generalized’’ hexagonal traveling wave patterns on the surface of a three-dimensional ideal fluid (i.e., stability of Generalized Short-Crested Wave (GSCW) solutions of the water wave problem). We restrict ourselves to a study of spectral stability which considers the linearization of the water wave opera...

In the paper the main attention is paid to conditions on algebras from a given variety Θ which provide coincidence of their algebraic geometries. The main part here play the notions mentioned in the title of the paper.

In this paper we characterize the rank two vector bundles on P 2 which are invariant under action of Gp := Stabp(PGL(3)), that fixes a point in projective plane, GL StabL(PGL(3)), line, and T = ∩ GL. Moreover, prove geometrical configuration jumping locus induced by invariance does not, other hand, itself. Indeed, find infinity families almost uniform but not homogeneous.

We study geometrical destabilization of inflation with the aim determining fate excited unstable modes. use numerical lattice simulations to track dynamics both inflaton and spectator field. find that is a short-lived phenomenon negative feedback loop prevents field fluctuations from growing indefinitely. As result, fields undergoing are merely shifted new classical configuration corresponding ...

Design and analysis of propellant grain configurations for determination of the grain geometry which is an important and critical step in the design of solid propellant rocket motors, because accurate calculation of grain geometrical properties plays a vital role in performance prediction. The performance prediction of the solid rocket motor can be achieved easily if the burn back steps of the ...

computer model of the patellofemoral joint was developed and the effects on the anterior displacement of the tibial tuberosity were investigated. the input geometrical and verification data for the model were obtained form an experimental study on a cadaver knee, mounted in an instron machine. the computer program found the configuration of the patellofemoral joint which satified both the geome...

A self-consistent system of nonlinear spinor and gravitational fields, modeled by static spherical symmetric metric, is considered studied. Exact solutions field equations in the Gravitational Theory are obtained. The nonlinearity lagrangian given an arbitrary function which depends on invariant generated from Fierz-Pauli bilinear form IS = S2. It shown that a soliton-like configuration has loc...

We study the steady-state low-temperature dynamics of an elastic line in a disordered medium below the depinning threshold. Analogously to the equilibrium dynamics, in the limit T-->0, the steady state is dominated by a single configuration which is occupied with probability 1. We develop an exact algorithm to target this dominant configuration and to analyze its geometrical properties as a fun...

New data regarding performance studies of Frisch-grid CdZnTe (CZT) detectors are presented. The Frisch-grid detector configuration under investigation is a bar shaped CZT crystal with the side surfaces coated with an insulating layer. A Frisch grid is fashioned by inserting the CZT bar into a metallic sleeve, or by depositing the metal directly upon the insulator; hence the semiconductor materi...
