A thorough understanding of thermal soil regimes is critical information for a wide variety of disciplines and engineering applications as well as for the evaluation of potential and limitations of thermal and optical sensors. In this study we have developed a procedure for the evaluation of global thermal soil regimes. First, pedotransfer functions are used to derive thermal soil properties (v...

A plain-weave wool fabric has been treated in a rollto-roll atmospheric pressure, post-discharge plasma equipment at three fabric speeds. The thermal properties of the treated fabric have been investigated by means of an Alambeta instrument. The thermal resistance and thermal diffusivity increased after the plasma treatment while the thermal absorptivity and volumetric heat capacity decreased. ...

In this study, the thermal performance of three kinds of roofs with different heat capacity and thermal conductivity under different external conditions has been investigated using a numerical method. For this purpose, the combined solar radiation, conduction and convection heat transfer were calculated implicitly in terms of a one-dimensional finite difference method. Different high and low so...

DESCRIPTION Concentrating Solar Power (CSP), also referred to as solar thermal power, uses mirrors to concentrate the sun's rays to heat a fluid that is then used to generate electricity, often using conventional steam turbines. There are three primary CSP technologies: parabolic trough, solar tower, and dish engine. The most common CSP system is the parabolic trough, which uses curved mirrors ...

This paper gives an overview of the current methods of calculation and optimization of active power reserve capacity. Methods used in the interconnected power systems of European countries and interconnected power systems of Baltic and Russia are described. The paper also represents the possibilities to utilize higher share of transmission capacity avoiding violation of thermal transmission lim...

A new method for analyzing second-order phase transitions is presented and applied to the polaronic system La(0.7)Ca(0.3)MnO3. It utilizes heat capacity and thermal expansion data simultaneously to correctly predict the critical temperature's pressure dependence. Analysis of the critical phenomena reveals second-order behavior and an unusually large heat capacity exponent.

We give a brief summary of the classical information capacity of single-mode free-space optical communication, both for pure-loss channels (i.e., with no background radiation), and for thermal-noise channels (i.e., with background radiation). We compare the capacities afforded by structured transmitters and receivers to that of the ultimate communication capacity. The ultimate capacity-achievin...

Vernacular building is considered as sustainable in energy consumption and environment and its thermal performance is more and more concerned by researchers. This paper investigates the thermal property of the vernacular building in Lhasa by theoretical analysis on the aspects of building form, envelope and materials etc. The values of thermal resistance and thermal capacity of the envelope are...
