There is a lot of current interest in sources of gravitational waves and active ongoing projects to detect such radiation, such as the LIGO project. These are long wavelength, low frequency gravitational waves. LISA would be sensitive to much longer wavelengths and lower fluxes. However compact stellar objects can generate high frequency (10 16 -10 21 Hz) thermal gravitational radiation, which ...

We analyze the properties of thermal radiation in photonic crystals and show that the spectral energy density, the spectral intensity, and the spectral hemispherical power are only limited by the total number of available photonic states and their propagation characteristics. In addition, we show that the central quantity that determines these thermal radiation characteristics is the area of th...

Shading the greenhouses is necessary in summer to reduce the solar radiation load. This however generates a considerable amount of thermal radiation heat load that needs to be removed via cooling systems. This study aimed to evaluate the effect of different shading configurations on the solar and thermal radiation in a greenhouse. Nets at four different locations were employed to shade the roof...

the present paper was aimed to study the effects of variable thermal conductivity and heat generation on the flow of a viscous incompressible electrically conducting fluid in the presence of a uniform transverse magnetic field, thermal radiation, porous medium, mass transfer, and variable free stream near a stagnation point on a non-conducting stretching sheet. equations of continuity, momentum...

A new auralization technique is presented for the objective and subjective assessment of loudspeakers in the large signal domain. On the basis of loudspeaker modeling and the linear, nonlinear and thermal parameters measured on a particular loudspeaker the instantaneous state variables (e.g. sound pressure output, displacement, temperature, ...) are calculated in real time for any input signal ...

In this paper, the first-order shear deformation theory is used to derive theoretical formulations illustrating the nonlinear dynamic response of functionally graded porous plates under thermal and mechanical loadings supported by Pasternak’s model of the elastic foundation. Two types of porosity including evenly distributed porosities (Porosity-I) and unevenly distributed porosities (Porosity-...

The effects of thermo-diffusion (Soret effect) and diffuso-thermal gradients (Dufour effect) on the unsteady incompressible magneto-hydrodynamic (MHD) free convection flow with mass transfer past a semi-infinite vertical plate in a Darcian porous medium in the presence of significant thermal radiation, first order homogenous chemical reaction and viscous heating are analyzed. The governing diff...

GENERAL CHARACTERISTICS OF energy is initially in the form of kinetic THERMAL RADIATION energy of the weapon debris. This kinetic energy is also absorbed by the air 7.01 One of the important difat a slightly later time \(§ 2.109) and ferences between a nuclear and a conserves to further heat the air. The heated ventional high-explosive weapon is the air, which constitutes the fireball, in turn ...

The study of fluid dynamics due to the stretching surface is one most eminent topics its potential industrial applications viz. drawing wire and plastic films, metal polymer extrusion, fiber glass production. In present article, author going effects hybrid nanofluids flow on an inclined plate including CuO (Copper Oxide), Cu (Copper). Casson with a couple-stress term has been used in analysis. ...

A theoretical investigation is performed for studying the flow of heat transfer characteristics of Sakiadis and Blasius flow of magnetohydrodynamic Maxwell fluid with thermal radiation. We also incorporated the Cattaneo-Chirstov heat flux model to control the heat transfer phenomena. Numerical solutions are carried out by using Shooting technique. The effects of various governing parameters on ...
