Spatial Simple Waves on a Shear Flow

Journal of Applied Mechanics and Technical Physics, 2002
The paper studies simple waves of the shallow-water equations describing three-dimensional wave motions of a rotational liquid in a free-boundary layer. Simple wave equations are derived for the general case. The existence of unsteady or steady simple waves adjacent continuously to a given steady shear flow along a characteristic surface is proved ...

Tourist flows and spatial behavior

2014
It is important to understand tourist movements to gain a better idea of tourist behavior, the operationalization of motives, and how to better manage destinations. The study of movements, historically, has been inhibited by a number of pragmatic method challenges. As such, most research focused on modeling interdestination movement patterns. Recently,

The stability of spatially periodic flows

Journal of Fluid Mechanics, 1981
The stability characteristics for spatially periodic parallel flows of an incompressible fluid (both inviscid and viscous) are studied. A general formula for the determination of the stability characteristics of periodic flows to long waves is obtained, and applied to approximate numerically the stability curves for the sinusoidal velocity profile. The

SUBCRITICAL SPATIAL TRANSITION OF SWEPT HIEMENZ FLOW

Proceeding of Seventh International Symposium on Turbulence and Shear Flow Phenomena, 2011
Abstract It is known from experimental investigations that the leading-edge boundary layer of a swept wing exhibits transition to turbulence at subcritical Reynolds numbers, i.e. at Reynolds numbers which lie below the critical Reynolds number predicted by linear stability theory.

Spatially varied flow equations

Water Resources Research, 1969
The momentum and energy principles are equally applicable in the derivation of spatially varied flow equations. By applying the energy principle and introducing a slope of energy head Se, the resulting spatially varied flow equation takes a different form of several terms containing the slope and the effect of added or extracted discharge from the ...

Spatial arrangement of color flows for video retrieval

IEEE International Conference on Multimedia and Expo, 2001. ICME 2001., 2001
Retrieval of video based on high-level content requires that models are developed to map low level perceptual features into high level semantic concepts. Commercials are a video category where the link between low level perceptual features and high level semantics is stressed, since the way colors are chosen and modified throughout a spot create a ...

Concepts of Spatially Varied Flow

Volume 1, 2004
By presenting relationships for spatially varied flow with combined increasing and decreasing discharge, and relating those relationships to prior work, a clearer exposition of spatially varied flow concepts is provided. The applicability and usefulness of energy (First Law of Thermodynamics) and momentum (Newton’s Second Law) principles to spatially ...

Spatial Decay Estimates for Flow in a Porous Medium

SIAM Journal on Mathematical Analysis, 1997
Summary: In the spirit of the recent work of \textit{K. A. Ames, L. E. Payne}, and \textit{P. W. Schaefer} [SIAM J. Math. Anal. 24, No. 6, 1395-1413 (1993; Zbl 0787.35060)], the decay of flow in a porous medium through a semi-infinite pipe is investigated. The analysis presented in this paper is based on the Brinkman--Forchheimer model. In establishing

Knowledge Flows and Their Spatial Extent

2011
The empirical evidence produced in Chap. 4 has suggested that not only innovative activities pursued locally affect regional economic performance but also those pursued in neighbouring regions play a positive and significant effect. On the basis of this evidence we analysed how different indigenous socio-economic conditions may result in a differential
