The proposed system in this paper enables the temperature controlled permittivity extraction of liquids up to 40 GHz from 10 to 40 °C. The temperature controlled environment consists of a temperature controlled chuck, probe station and a CPW microwave sensor that is coupled to a miniature T-type thermocouple. A large thermal mass and a platinum wire resistor ensure a precise reference temperature...
The performance of the main memory is an important factor on overall system performance. To improve DRAM performance, designers have been increasing chip densities and the number of memory modules. However, these approaches increase power consumption and operating temperatures: temperatures in existing DRAM modules can rise to over 95°C. Another important property of DRAM temperature is the large...
In the compound insulation which is comprised of cable accessory (e.g. terminal or sheath of cable), interface between different dielectrics or electrode and dielectric is often claimed to be the weakest points due to space charge accumulation and then the increase of adjacent electrical field. Furthermore, the higher temperature of cable conductor caused by Joule heating leads to conductivity gradient...
Accurate measurement of the acoustic wave flying time in furnace is the key of acoustic measurement technology of furnace temperature distribution. This paper proposes the acoustic wave flying time measurement method based on the second related technologies. First, the received signal is dealt with autocorrelation process, and then it is dealt by cross-correlation with reference signal, which realizes...
The acoustic ray refraction on measuring temperature field of large-scale coal-fired power plant furnace is an important factor affects the accuracy of measuring the temperature field, If can simulate the propagation of the true path of the acoustic waves will further enhance the accuracy of the reconstruction of temperature field. This paper proposes a two-dimensional temperature field reconstruction...
