- Globally Stable Control of Three-phase Three-wire Shunt Active Power Filters. Hasan K�m�rc�gil; Osman K�krer // Electrical Engineering;May2007, Vol. 89 Issue 5, p411
Abstractï¿½ï¿½This paper proposes a new control strategy for three-phase three-wire shunt active power filters. The idea in this strategy is to form an energy-like Lyapunov function in terms of the active filter states and then determine the control law that makes the time derivative of...

- Elevator Shunt Trip, Part 3. Winslow, Dan // Elevator World;Feb2011, Vol. 59 Issue 2, p28
The article discusses the use of elevator shunt trip from a Canadian perspective. It explains why Canada has chosen to ignore the entire issue of shunt trip under the National Building Code of Canada. It provides information on some definitions in the model codes including elevator control,...
- Ventriculoperitoneal shunt dislodgement after a haircut with hair clippers in two shunted boys. Meng-Fai Kuo; Huei-Shyong Wang; Shih-Hung Yang // Child's Nervous System;Nov2009, Vol. 25 Issue 11, p1491
Hair clippers are widely used to cut hair short at the occipital region for Asian school boys. A haircut as the cause of shunt dislodgement has not previously been reported. Two previously shunted boys presented with shunt dysfunction 1 to 2 days after a haircut during which hair clippers were...
