Performance and Thermal Comfort

Ergonomics, 1971
This 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, 2022
AbstractThe 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

Thermal Performance of Equestrian Helmets

2019
The 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.

Buildings that Perform: Thermal Performance and Comfort

2018
Building performance evaluation considers the whole building system from a fabric, service and occupant perspective, as well as its response to the environment and potential integration into smart cities. There are many BPE methods used to collect building data and inform designs.

Thermal Cycling Performance

2014
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.

Effect of Thermal State and Thermal Comfort on Cycling Performance in the Heat

International Journal of Sports Physiology and Performance, 2015
Purpose:To determine the effect of thermal state and thermal comfort on cycling performance in the heat.Methods:Seven well-trained male triathletes completed 3 performance trials consisting of 60 min cycling at a fixed rating of perceived exertion (14) followed immediately by a 20-km time trial in hot (30°C) and humid (80% relative humidity) conditions.

Thermal Performance of Thermally Enhanced PBGA Packages

Advances in Electronic Packaging, Parts A, B, and C, 2005
Enhancement 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 ...
