Magnetically Mediated Thermoacoustic imaging (MMTAI) is a noninvasive imaging approach for electrical impedance. It collects ultrasound signals induced by thermal expansion to reconstruct the conductivity of the object with high spatial resolution and high contrast. Previously reported experimental results on MMTAI only were obtained from the high conductivity samples like the metal. In the study,...
In such computerized systems, such as voice control units, personal identification, IP-telephony, weapon control commands, accepting applications for reference services, automated stenography, recognition of individual words and phrases plays a major role in enhancing the effectiveness of technical systems. In the preliminary stages of speech processing algorithms for the allocation of phonetic characteristics...
In short range ultrasonic measurement systems, the blind area of the measurement limit the application of the low cost ultrasonic transducers. In a double transducer measurement system, when impulses are loaded to transmitter with reflection and refraction of sonic, the receiver nearby will receive echoes immediately, which will leads to a period of time that can't be measured. If an object is near...
