Specific signal processing for high frequency range in Audio - Magnetotelluric
The usual methodology used in magnetotelluric signal processing (MT) has been studied and applied to the case of audio-magnetotellourics (AMT). The results obtained have proved not to be good enough in order to obtain a good subsurface resistivity model. Therefore, some changes have been made to the methodology of signal processing so that it suits audio-magnetotellurics. These changes have app...
متن کاملElectrical Resistance Measurements of Kaolinite and Serpentine Powders during Dehydroxylation*
Direct current resistance measurements were made of kaolinite and serpentine powders to follow the changes in resistances during their dehydroxylation processes in air. The resistance of kaolinite remained almost constant during the dehydroxylation, whereas that of serpentine showed a rapid decrease. The formation of distorted lattice sites where the charge carriers are scattered under an elect...
متن کاملEnvironmental Sound Recognition With Time-Frequency Audio Features
The paper considers the task of recognizing environmental sounds for the understanding of a scene or context surrounding an audio sensor. A variety of features have been proposed for audio recognition, including the popular Mel-frequency cepstral coefficients (MFCCs) which describe the audio spectral shape. Environmental sounds, such as chirpings of insects and sounds of rain which are typicall...
متن کاملAudio Replay Attack Detection Using High-Frequency Features
This paper presents our contribution to the ASVspoof 2017 Challenge. It addresses a replay spoofing attack against a speaker recognition system by detecting that the analysed signal has passed through multiple analogue-to-digital (AD) conversions. Specifically, we show that most of the cues that enable to detect the replay attacks can be found in the high-frequency band of the replayed recordin...
متن کاملEffect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat
The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...
