estimating the regolith depth from brightness temperature (TB) measured by a multi-channel radiometer at 3GHz, 7.8GHz, 19.35GHz and 37GHz. To establish the accurate microwave radiation or scattering model of lunar surface, firstly we need to determine an accurate model of dielectric constant of lunar regolith. However, until now there is no model of dielectric constant suitable for microwave band...
A fully dynamic flash ADC is attractive for its low-power and low-input capacitance natures. It has minimal static current consumption, and its power and area costs diminish as process advances. However, the comparators thresholds, which are set by the built-in offsets, are sensitive to supply and temperature drifts. This threshold variation may result in up to ±20% ADC gain error with ENOB degradation...
We can judge the diesel active state by measuring the turbo supercharger speed, but in practical measurement, there are always many problems. In this paper, we build the regression model of relationship between turbo supercharger speed and pressure ratio, intake flow, turbine final pressure, turbine front pressure, turbine final temperature, gas compressor final pressure, gas compressor front pressure...
A design of detection system about dissolved oxygen is proposed based on C8051F020 which is an integrated mixed-signal system-on-chip MCU. It can quickly and accurately detect Dissolved Oxygen (DO) in the water. The software adopts Multi-sensor data fusion and temperature compensation to eLiminate the effects of temperature and the sensor itself, enhance the measurement precision. And serial communication...
In this research, the ZnO biosensor is successfully grown on the (100) silicon substrate. The lithography technology is sued to fabricate the biosensor. The test system of humidity sensor is constructed in our laboratory with measurement information system. The test information system can precisely examine the relativity humidity message of environment. The impedance information of ZnO biosensor is...
A new pesticide residues detection instrument based on enzyme inhibition method is developed. The amount of pesticide residues is determined by measuring the light absorbency of the sample liquid after inhibition reaction. The influence of temperature on the activity of enzyme and the inhibition rate of enzyme is analyzed. A new method of temperature calibration based on RBFNN (Radial Basis Function...
Temperature control system has been widely used over the past decades. In this paper, a general architecture of distributed temperature control system is put forward based on multi-sensor data fusion and CAN bus. A new method of multi-sensor data fusion based on parameter estimation is proposed for the distributed temperature control system. The major feature of the system is its generality, which...
