Behavior of the PMD coefficient of optical links under influence of mechanical and thermal effects
(2004-12-01)
This papers presents results on the variation of the PMD coefficient of optical links under influence of mechanical tests, such as tensile strength, bending and compression, and also during the application of a thermal ...
Thermal diffusivity of polymers by modified angstrom method
(ELSEVIER SCI LTD, 2010)
The nature of the molecular structure of plastics makes the properties of such materials markedly temperature dependent. In addition, the continuous increase in the utilization of polymeric materials in many specific ...
Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...
METHODOLOGY FOR THERMAL SIMULATION OF ELECTRONIC DEVICES WITHOUT KNOWING THE THERMAL DISSIPATION
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2016-01-01)
Electronic components with high thermal dissipation, can cause serious problems for the developed product. The electronic components are limited by the maximum operating temperature, this characteristic is called junction ...
Thermal behavior of metallic and fiber cement tiles with simple and double layers
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
This research was conducted aiming to evaluate the thermal behavior of metallic and fiber cement tiles installed in simple and double layers. The experiment was performed on prototypes of roofing in single layers and ...
Non-destructive thermal wave method applied to study thermal properties of fast setting time endodontic cement
(American Institute of Physics (AIP), 2013-11-21)
The thermal wave method is applied for thermal properties measurement in fast endodontic cement (CER). This new formula is developed upon using Portland cement in gel and it was successfully tested in mice with good ...

Purpose: This study aimed to evaluate the effect of different storage periods in artificial saliva and thermal cycling on Knoop hardness of 8 commercial brands of resin denture teeth. Methods: Eigth different brands of ...
Evolutionary design of a satellite thermal control system: Real experiments for a CubeSat mission
(Pergamon-Elsevier Science Ltd., 2016)
This paper studies the use of artificial evolution to automate the design of a satellite passive thermal control system. This type of adaptation often requires the use of computer simulations to evaluate fitness of a large ...
Thermophysical Properties of Brazilian Orange Juice as Affected by Temperature and Water Content
(1998-10-01)
The specific heat, thermal conductivity, thermal diffusivity and density of Brazilian orange juice were determined between 0.34 and 0.73 (w/w) water content and with temperatures from 0.5 to 62°C. The experimental data ...
