The DEMO wall load challenge

Ambrogio Fasoli, Jonathan Graves, Jan Horacek, David Pfefferlé, Samuel Lanthaler, Bernhard Sieglin, Hartmut Zohm

For several reasons the challenge to keep the loads to the first wall within engineering limits is substantially higher in DEMO compared to ITER. Therefore the pre-conceptual design development for DEMO that is currently ongoing in Europe needs to be based ...

Digitally controlled analog proportional-integral-derivative (PID) controller for high-speed scanning probe microscopy

Georg Fantner, Nahid Hosseini, Adrian Pascal Nievergelt, Maja Dukic Pjanic, Santiago Harald Andany, Chen Yang

Nearly all scanning probe microscopes (SPMs) contain a feedback controller, which is used to move the scanner in the direction of the z-axis in order to maintain a constant setpoint based on the tip-sample interaction. The most frequently used feedback con ...

Arbitraging Intraday Wholesale Energy Market Prices With Aggregations of Thermostatic Loads

Maryam Kamgarpour, John Lygeros

We investigate the potential for aggregations of residential thermostatically controlled loads (TCLs), such as air conditioners, to arbitrage intraday wholesale electricity market prices via non-disruptive load control. We present two arbitrage approaches: ...
