Phase balancing using simulated annealing

IEEE Transactions on Power Systems, 1999
Deregulation eliminates the boundary of the territory of the monopoly power industry. Competition forces utilities to improve power quality as well as to reduce investment and operation costs. Feeder imbalance describes a situation in which the voltages of a three-phase voltage source are not identical in magnitude, or the phase differences between ...

Unsupervised Multiphase Segmentation: A Phase Balancing Model

IEEE Transactions on Image Processing, 2010
Variational models have been studied for image segmentation application since the Mumford-Shah functional was introduced in the late 1980s. In this paper, we focus on multiphase segmentation with a new regularization term that yields an unsupervised segmentation model.

Precision Robotic Leaping and Landing Using Stance-Phase Balance

IEEE Robotics and Automation Letters, 2020
Prior work has addressed control of continuous jumping using touchdown angle from flight, but greater precision can be obtained by directing individual leaps using liftoff angle from stance. We demonstrate targeted leaping as well as balanced landing on a narrow foot with a small, single leg hopping robot, Salto-1P.
