New standoffs provide high-reliability component mounting for printed wiring boards [PDF]

open access: yes, 1974
Designs provide such advantages as inspectable solder joints from both sides of boards; stress relief in lead wires; low-impedance thermal paths; matched coefficients of lead wire thermal expansion; minimum webbing of conformal coatings to lead wires ...

Assessment of Two Methods of Enhancing Thermal Mass Performance of Concrete Through the Incorporation of Phase-Change Materials

open access: yesJournal of Sustainable Design and Applied Research in Innovative Engineering of the Built Environment, 2016
According to the IEA Technology Roadmap on Energy Efficient Building Envelopes, buildings are responsible for more than one third of global energy consumption, with space heating and cooling consuming 33% of this energy, and increasing to 50% in cold ...

On the thermal buffering of naturally ventilated buildings through internal thermal mass [PDF]

open access: yes
In this paper we examine the role of thermal mass in buffering the interior temperature of a naturally ventilated building from the diurnal fluctuations in the environment.

Impregnation of Wood with Microencapsulated Bio-Based Phase Change Materials for High Thermal Mass Engineered Wood Flooring

open access: yesApplied Sciences, 2018
Wood is a porous material that can be impregnated and have enhanced properties. Two species of hardwood, red oak (Quercus rubra L.) and sugar maple (Acer saccharum Marsh.), were impregnated in a reactor with a microencapsulated phase change material. The

Electric Screening Mass of the Gluon with Condensate at Finite Temperature

open access: yes, 1999
The electric screening mass of the gluon at finite temperature is estimated by considering the gluon condensate above the critical temperature. We find that the thermal gluons acquire an electric mass of order T due to the gluon condensate.Comment: 9 ...

Thermal rectification and negative differential thermal resistance in lattices with mass gradient

open access: yes, 2007
We study thermal properties of one dimensional(1D) harmonic and anharmonic lattices with mass gradient. It is found that the temperature gradient can be built up in the 1D harmonic lattice with mass gradient due to the existence of gradons. The heat flow

Heating Energy and Peak-Power Demand in a Standard and Low Energy Building

open access: yesEnergies, 2013
Building energy efficiency legislation has traditionally focused on space heating energy consumption. This has led to a decrease in energy consumption, especially in space heating.
