In view of the maloperation problem in traditional distance protection zone-III caused by overload in lines, an adaptive overload identification method based on the complex phasor plane is proposed in this paper. First, according to the geometric distribution of the measured phasors under different operating conditions, the virtual voltage drop phasor equation is established. And then, the adaptive...
Logic built-in self-test (LBIST) is commonly used for testing integrated circuits (ICs) in production and in the field. Due to the random nature of LBIST patterns, activation of random-pattern-resistant faults requires the application of numerous patterns, thus increasing test time in the field. In this work, we introduce a novel method to reduce LBIST pattern count and LBIST test time. The presented...
Microfluidics-based biochips are revolutionizing high-throughput sequencing, parallel immunoassays, blood chemistry for clinical diagnostics, and drug discovery. These devices enable the precise control of nanoliter volumes of biochemical samples and regents. They combine electronics with biology, and they integrate various bioassay operations, such as sample preparation, analysis, separation, and...
Although pseudo-orthogonal carrier interferometry (PO-CI) multi-carrier code division multiple access (MC-CDMA) could transmit doubled data streams, it highly depends on the modulation type. Through theoretical inter-code interference analysis, this paper puts forward that PO-CI/MC-CDMA systems could be de-spread ideally only with BPSK modulation. When complex modulation types are considered, PO-CI/MC-CDMA...
Dependability is an important system attribute for microfluidic lab-on-chip devices. On-line testing offers a promising method for detecting defects, fluidic abnormalities, and bioassay malfunctions during chip operation. However, previous techniques for reading test outcomes and analyzing pulse sequences are cumbersome, sensitive to the calibration of capacitive sensors, and error-prone. We present...
