the aim of this study was to determine the effect of motivational self-talk as one of the psychological strategies. motivational self-talk is a type of self-talk that appears to improve performance and control arousal level through increased drive and effort and positive motivation in performance. this study tried to investigate the effect of motivational self-talk on performance of simple and ...

Buoyancy-induced (Rayleigh-Bénard) convection of a fluid between two horizontal plates is a central paradigm for studying the transition to complex spatiotemporal dynamics in sustained nonequilibrium systems. To improve the analysis of experimental data and the quantitative comparison of theory with experiment, we have developed a three-dimensional finite-difference code that can integrate the ...

Few years ago we developed jointly with I.Dynnikov new discretization of complex analysis (DCA) based on the two-dimensional manifolds with colored black/white triangulation (see [1]). Especially deep results were obtained for the Euclidean plane with equilateral triangle lattice. In the present work we develop a DCA theory for the analogs of equilateral triangle lattice in Hyperbolic plane. So...

The Markov moment problem is to characterize sequences s0, s1, s2, . . . admitting the representation sn = ∫ 1 0 x f (x) dx, where f (x) is a probability density on [0, 1] and 0 ≤ f (x) ≤ c for almost all x. There are well-known characterizations through complex systems of non-linear inequalities on {sn}. Necessary and sufficient linear conditions are the following: s0 = 1, and 0 ≤ (−1)n−j ( n ...

In this paper, entire solutions of a class non-linear difference equations are studied. Under some conditions, we find that the set common limiting directions Julia sets solutions, their derivatives and primitives must have definite range measure.
