People working indoors often respond very differently to levels of thermal comfort in the office, which is directly related to health and work efficiency. Up to now, the dilemma of thermal comfort for all and energy efficiency in the process remains unsolved. A local dynamic thermal comfort model is established in this paper based on the CFD software. Local parameters are designated and all-around...
In order to investigate control method for indoor thermal comfort, the experimental environment of indoor thermal comfort is designed in this paper. Thermal comfort data are collected based on questionnaire means, ANN (artifical neural network) is trained using the data, and the ANN model trained can accurately forecast thermal comfort index. Relevant input parameters is conversely computed based...
Ground clutter characteristics of airborne pulse Doppler radar affected by some factors such as antenna array orientation, pulse repetition frequency. This paper analyzed the ground clutter characteristic of airborne forward looking pulse Doppler radar in high PRF, pointed out some notable features of the clutter, presented the results of clutter simulation, thereby offering valuable reference for...
If the mirror Doppler frequency components not be suppressed well in airborne pulsed Doppler radar, which would bring on false target detection, how to suppress the mirror Doppler frequency is an important issue to enhance radar performance. This paper proposed an method for the suppression of mirror Doppler frequency based on Hilbert transform, the results of processing experiment data show the suppression...
