This paper proposes a novel real-time measurement method of the dynamic magnetic flux in magnetically controlled devices based on the type-c transducer. The principle of the device is using an auxiliary core with an auxiliary winding to inject a high-frequency signal. Because the auxiliary core shares a partial magnetic path with the main iron core, the output current in the auxiliary winding will...
Recently, although the technique and the equipment of copper smelting in China has been among advanced international levels, there are still some problems on high energy consumption and instable quality of products. These problems need to be solved by improving automation technique urgently. Soft measurement of key parameters is one of these technologies to improve the automation level of copper smelting...
Photoplethysmogram is widely used to measure heart rate and arterial blood oxygen saturation in hunman. A Sensor interface circuit for circuit for Bloodbeat measurement using PPG(Photoplethysmogram) is proposed and designed by using current-control schmitt trigger in this paper. This circuit detects the blood beat using PPG which occurs in bloodbeat sensor and composed of analog and digital blocks...
In current COTS software components evaluation methods, the resulting scores only represent relative ranking of the alternatives and the differences in their value does not give any indication of their relative superiority. Based on gap analysis theory, a new evaluation approach is proposed in this paper. The functional and non-functional gap between COTS components and system requirements are identified...
The precision of impedance fault location algorithm is deteriorated by the extremely large shunt capacitance in UHV line. And the traditional improved ways are all invalid caused by the nonlinearity of measurement impedance in relay and the frequent variations of operation modes in UHV system. In response to this question, a novel impedance fault location algorithm is proposed for phase faults. It...
