Performance and Thermal Comfort
Ergonomics, 1971This experiment attempts to establish an objective measure of thermal comfort. A theoretical explanation of the relationship between performance and comfort is given and is represented in terms of an hypothesis. A total of 50 subjects was divided among five groups, each group experiencing one temperature in the range 15.6-26.7°C (60-80°F) for both air ...

Performance of Thermal Interface Materials
Small, 2022AbstractThe thermal interface materials (TIMs) used for improving thermal contacts are considered in terms of the performance, performance consideration criteria, performance evaluation methods, and material development approaches. The performance is described mainly by the thermal contact conductance, which refers to the conductance across the thermal

Assessing cement plant thermal performance
2016 IEEE-IAS/PCA Cement Industry Technical Conference, 2016Energy consumption is one of the largest cost components in the production of Portland cement. Energy is consumed through the fuel required to make the cement, as well as the electricity consumed to operate the manufacturing equipment. This paper discusses the fuel requirements for driving the chemical processes are the starting point for the ...

LSST mirror thermal performance
SPIE Proceedings, 2004The proposed science missions of the LSST require a telescope with an optical etendue of greater than 250 meters square degrees square. The current LSST Baseline Configuration has a field of view of 3.5 degrees and an optical etendue of 302 m 2 d 2 .

Thermal Performance of Thermally Enhanced PBGA Packages
Advances in Electronic Packaging, Parts A, B, and C, 2005Enhancement of thermal performance of a PBGA (plastic ball grid array) is often accomplished by embedding metal layers in the substrate and the inclusion of a copper spreader in the mold compound. The thermal effectiveness of the substrate planes in spreading the heat is frequently compromised by the necessity to separate the various voltages on the ...

Thermal Performance of Equestrian Helmets
2019The cooling performance of three equestrian helmets was investigated within this research. The helmets were evaluated for their capacity to remove convective heat loss in the scalp area with the use of a thermal manikin head with nine thermal zones. The manikin head was placed in a climate chamber with an open loop wind tunnel.

On-off operation of electronic systems leads to thermal cycling, which introduces thermal and strain energy into solder joints, resulting in microstructural evolution mechanisms of recovery, recrystallization and damage nucleation. The thermal strain history is very sensitive to the package design.
