Abstract It is observed that the feather surface exhibits anisotropic resistances for streamwise and spanwise flows. To obtain a qualitative understanding about effect of this resistance feature on boundary-layer transitional flow over flat plate, simple phenomenological model established in paper. By means large eddy simulation (LES) with high-order accurate finite difference method, numerical...

We show that Regge phenomenology is consistent with the only universal scaling law for hadron masses, M * /M = (α ′ /α ′ *) 1/2 , where asterisk indicates a finite-temperature quantity. Phenomenological models further suggest the following expression of the above scaling in terms of the temperature-dependent gluon conden-sate: M * /M = (α ′ /α ′ *) 1/2 = (G a µν * /G aµν) 1/4. It is known that ...

the famous theory in the field of textual meaning and interpretation is called “intentionalism” and on that basis, “the intention of the author of a work is in relation to the meaning of the work or its interpretation”. in recent years, a theory has been widely developed in contrast to the (above) famous theory, titled the theory of “anti-intentionalism”, or in its extreme form, the theory of “...

In this review, which is intended as an introduction to the subject, we introduce the phenomenological transport coefficients in solid-state diffusion and discuss their structure and physical meaning. Next, we discuss the Darken, the Manning, the Moleko, Allnatt and Allnatt and the Heumann expressions which relate the phenomenological coefficients to the (measurable) tracer diffusion coefficien...

This paper deals with black holes, bubbles and orbifolds in GaussBonnet theory in five dimensional anti de Sitter space. In particular, we study stable, unstable and metastable phases of black holes from thermodynamical perspective. By comparing bubble and orbifold geometries, we analyse associated instabilities. Assuming AdS/CFT correspondence, we discuss the effects of this higher derivative ...

The optical properties of composite materials are studied theoretically as a function of temperature via a phenomenological model for temperatures up to the melting points of the materials. Both the Maxwell-Garnett and Bruggeman models are considered and the temperature variation of the optical constants of the metallic particles is obtained with an account of the dependence of both the electro...

The change in entropy, DS , at the first-order magnetoelastic phase transition in Gd5(SixGe12x)4 alloys for x<0.5 has been measured with a high-sensitivity differential scanning calorimeter with built-in magnetic field, H. Scaling of DS is achieved by changing the transition temperature, Tt , with x and H from 70 to 310 K. Tt is thus the relevant parameter in determining the giant magnetocalori...

A recently developed long-wavelength continuum phenomenological model is employed to study the phonon tunneling through semiconductor heterostructures where the barrier parameters are varied gradually according to a Gaussian function. The optical modes of a Si/SixGe1Kx Gaussian superlattice are considered. Such structures allow the incident phonons to be nearly totally transmitted when the inci...

Hegel’s Phenomenology of Spirit is knowledge’s voyage of self-discovery. It begins with the mere appearance of knowledge – that is, what knowledge at first seems to be. But what knowledge at first seems to be is not congruent with its reality, even in its first appearance. The incongruence creates an instability that pushes knowledge on to other ways to take itself, stopping only when a concept...
