TEC and TEC Controller for Temperature-Stabilized Plate
نویسندگان
چکیده
To obtain accurate measurements for brightness temperature from the IIP radiometer, it is necessary to know the temperature of the front-end components especially low noise amplifier (LNA) and microwave terminator during measurements. For this application, all of these components will be placed on a temperature-stabilized metal plate which can be achieved by using a thermoelectric cooler (TEC). In this report, criteria for choosing a TEC and its controller are explained. Details for setting up the controller are also presented. Measurements of temperature distribution on a plate and temperature as a function of time by using the temperature monitoring circuit developed in [1] illustrate the successful operation of this TEC controller.

Flexural Strength of Preheated Resin Composites and Bonding Properties to Glass-Ceramic and Dentin
To test the impact of preheating (25, 37, 54, or 68 °C) of TetricEvoCeram (TEC), FiltekSupremeXT (FSXT), and Venus (V) on flexural strength (FS), shear bond strength (SBS) and interfacial tension (IFT). FS was tested with TEC and FSXT. For SBS, glass-ceramic and human dentin substrate were fabricated and luted with the preheated resin composite (RC). SBSs of 1500 thermal cycled specimens were m...

The Total Electron Content (TEC) measured by the Global Positioning System (GPS) is useful for registering the pre-earthquake ionospheric anomalies appearing before a large earthquake. In this paper the TEC value was predicted using the singular value thresholding (SVT) method. Also, the anomaly is detected utilizing this predicted value and the definition of the threshold value, leading to the...

An innovative micro-test structure for detecting the thermal expansion coefficient (TEC) of metal materials is presented in this work. Throughout this method, a whole temperature sensing moveable structures are supported by four groups of cascaded chevrons beams and packed together. Thermal expansion of the metal material causes the deflection of the cascaded chevrons, which leads to the capaci...
