PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...

We simply adapted the official Matlab code into Python (in our tests they both give the same results). First (1.), we calculate the Average Precision (AP), for each of the classes present in the ...

We present a low-power gas sensor design based on a capacitive micromachined ultrasonic transducer (CMUT), for use on self-powered wearable platforms. Earlier a CMUT-based sensor, with 70-mW power ...

Air-gapped workstations are separated from the Internet because they contain confidential or sensitive information. Studies have shown that attackers can leak data from air-gapped computers with ...

An electrochemical DNAzyme sensor for sensitive and selective detection of lead ion (Pb2+) has been developed, taking advantage of catalytic reactions of a DNAzyme upon its binding to Pb2+ and the use ...
