Accurately measuring the oil content and salt content of crude oil is very important for both estimating oil reserves and predicting the lifetime of an oil well. There are some problems with the current methods such as high cost, low precision, and difficulties in operation. To solve these problems, we present a multifunctional sensor, which applies,(More)
In electroencephalography (EEG)-based emotion recognition systems, the distribution between the training samples and the testing samples may be mismatched if they are sampled from different experimental sessions or subjects because of user fatigue, different electrode placements, varying impedances, etc. Therefore, it is difficult to directly classify the(More)
When insulation fault occurs in the ignition coil partial secondary winding discharges. Random pulses with various amplitudes appear in primary current and secondary voltage waveforms simultaneously. Moreover the secondary voltage may distort if the fault is serious. Traditional methods are difficult to identify the discharge pulses. This paper examines a(More)
