Ninth Circuit Court of Appeals Judges Mark Bennett of Honolulu, Eric Miller of Seattle, and Jennifer Sung of Portland — presided over the hearing remotely in a case simply titled Trump v. Newsom.

How to use a circuit breaker finder to understand your home's wiring (and why it matters so much) I almost paid for new wiring - until this Klein tool showed me the power was already there.

In this paper, we identify two basic methods for designing serial reduction circuits: the tree-traversal method and the striding method. Using accumulation as an example, we analyze the design ...

This paper proposes a cascaded Proportional Integral-Fractional Order Proportional-Integral-Derivative (PI-FOPID) controller to improve the frequency response of a hybrid microgrid system. The optimum ...

A system that uses a PID controller to balance a ball on a tiltable platform. The system is built with an Arduino, ultrasonic sensor, and servo motor, with PID gain tuning via potentiometers. The ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.
