The land surface temperature (Ts) is an important parameter in land surface and atmosphere studies. A set of synchronously observed “ground-truth” temperature as training data is required for some empirical/semiempirical statistical and neural network methods for retrieving Ts from passive microwave (PMW) remote sensing data. To provide information for the choice of the most suitable dataset in Ts...
This paper presents simulation-based optimization of an orthogonal-coil RF probe for miniature implantable pressure sensors. The geometric parameters of the orthogonal coils were optimized for the most efficient telemetry operation. In addition, impact of the operating frequency on sensitivity of the pressure measurement was investigated. The simulation results demonstrate that optimized orthogonal...
The paper presents an analysis of self-heating effect on micro-machined temperature difference air flow sensor, and demonstrates through modeling and simulation that self-heating effect can influence the output of the air flow sensor. The mathematical model of the sensor based on an existing microsensor chip is set up, and some details of the chip structure are considered in the model. The sensor's...

The air-gaps will appear in the ice-layer during icing and ice-melting process of composite insulators. The icing flashover process and flashover voltage are obviously affected by the air-gaps. In order to research the influence of the air-gaps on the icing flashover performance of composite insulators, the icing flashover tests were carried out by using the plate model of insulators. The influence...
Typical icing morphology, including bridged and non-bridged icicles, affects the electrical strength of energized transmission line insulators under melting conditions. This paper is concerned with melting process of multi-icicles and its flashover performance. Two different models with the same gap length was tested and compared. It was found that partial discharge in bridged icicle occurred from...
Typical icing morphology, including bridged and non-bridged icicles, affects the electrical strength of energized transmission line insulators under melting conditions. During the experiment result shown in this paper, there are two kind of discharge patterns due to icing morphology difference. For non-bridged icicles, melting leading to droplet ejection was analyzed during flashover experiments....
