For simplicity, we adopt the following rules: n denotes an element of N, X, X1 denote sets, r, p denote real numbers, s, x0, x1, x2 denote real numbers, S, T denote real normed spaces, f , f1, f2 denote partial functions from R to the carrier of S, s1 denotes a sequence of real numbers, and Y denotes a subset of R. The following propositions are true: (1) Let s2 be a sequence of real numbers an...

OBJECTIVE To evaluate the performance of adult young subjects in a Random Number Generation (RNG) task by controlling the response speed (RS). METHOD Sixty-nine university students of both sexes took part in the experiment (25.05 +/- 6.71 year-old). Participants were alloted into 3 groups which differed in RS rates to generate numbers: 1, 2 and 4 seconds to generate each number. A digital met...

جریان­های غلیظ به طور کلی به دو دسته جریان­های غلیظ پایدار(مانند جریان غلیظ نمکی) و جریان­های غلیظ ناپایدار(مانند جریان غلیظ رسوبی یا جریان کدر) تقسیم­بندی می­شوند. رخداد این گونه از جریان­ها در مخازن سدها باعث انتقال رسوبات به نزدیکی بدنه سد و ایجاد خطر برای تاسیسات و سازه­های در نظر گرفته شده برای تامین اهداف سد می­شود. یکی از این روش­ها، خارج کردن رسوبات حاصل از جریان­های سیلابی، با ...

Based on interactions between number and space apparent from healthy subjects' randomization attempts we expected random number generation (RNG) to be sensitive for the monitoring of unilateral spatial deficits. Specifically, we predicted patients with left-sided hemineglect to evidence "neglect in number space", i.e. to produce a deficiency in the generation of small, "left-sided" numbers. In ...

Abstract The purpose of this paper is to clarify the properties of road network patterns by considering the relationship between neighborhood intersections. The Relative Neighborhood Graph (RNG), which is one of the proximity graph, is used to analyze the road network patterns of major cities in the United States as a network construction model. The grid-tree proportion (GTP) index and the cros...

1. Objective The objective is to understand and extend a recent theory of turbulence based on dynamic renormalization group (RNG) techniques. The application of RNG methods to hydrodynamic turbulence has been explored most extensively by Yakhot and Orszag (1986). They calculate an eddy viscosity consistent with the Kolmogorov inertial range by systematic elimination of the small scales in the f...

Most indoor airflows are mixed convection. In order to simulate mixed convection accurately and efficiently, this paper uses a two-layer turbulence model. The two-layer model combines a one-equation model for near wall flow together with the standard k-epsilon model for outer-wall flow. The model has been used to predict the mixed convection by displacement ventilation in an office. The compute...
