Previous methods of designing a bolt supporting network, which depend on engineering experiences, seek optimal schemes in terms quality. The cost and time, however, have not been considered, restricts their applications real-world situations. We formulate the problem network as three-objective optimization model by simultaneously considering such indicators quality, economy, efficiency. Especially, two surrogate models are constructed support vector regression for roof-to-floor convergence...
We report a high-quality-factor ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</i> ) film bulk acoustic resonator (FBAR) operating in liquid environments. By integrating microfluidic channel to longitudinal-mode FBAR, of up 150 is achieved with direct contacting. A transmission line model used theoretically predict the behavior FBAR. The suggests an oscillatory pattern as function thickness and wavelength liquid, which experimentally verified...
A CMOS Capacitance-to-Digital Converter (CDC) for capacitive sensors array applications is presented. It consists of a 16:1 multiplexer, capacitance-to-voltage front-end and 16-bit voltage-to-pulses converter. The proposed circuit extends the dynamic range by charging or discharging measured indirectly. For low power consumption short conversion time, hardware reuse technique multi-steps quantization method have been applied in voltage-to-digital pulse converter design. This 16-ch CDC's...
Iron and manganese leaching into water <italic>via</italic> precipitation can cause pollution. We evaluate the contamination of iron through behavior response, finally to obtain an online monitoring method on heavy metal pollution in water.
Linear regulators have output specifications far superior to switch-mode techniques, except for the overall efficiency. This efficiency limitation can be overcome by applying a very low frequency supercapacitor circulation technique at input side of dropout regulator IC. The was proven in 12V 5 V versions, and, easily applied other power supplies such as 3.3V or 1.5V versions required various processors. paper outlines concepts and experimental results related this technique. With commercial...
In the process of artificial interventional therapy, operation catheter is not accurate, which will bring strong radiation damage to surgeons.
