The objective of this paper is to analyse the trade-off between cost operation and system reliability resulting from different shapes Operating Reserve Demand Curves under scarcity pricing. We implement a model short-term Belgium we validate it against historical realisations operation. implemented using 4 embedded optimization problems. simulates lag mobilizing flexible resources versus increa...

Planned offsets of the STIS Mode Select Mechanism (MSM) result in changes to the nominal calibration curves, particularly noticeable in the echelle modes. The spectral wave calibration exposures (wavecals) obtained with each observation can be used to predict a simple, linear offset of the nominal calibration curve to be used for each MSM shift. In addition, a time dependent variation has been ...

A portion of a commercial power grid is used in the development of a pair of related power supply transient current (IDDT) fault detection and localization methods. The methods analyze regional signal variations introduced by defects at a set of the power supply ports on the chip under test (CUT). Current fractions are computed using the areas under the IDDT waveforms generated at neighboring o...

Wireless sensor network protocols and applications, including those used for localization, topology control, link scheduling, and link quality estimation, make extensive use of Received Signal Strength Indication (RSSI) measurements. In this paper we show that inaccuracies in the RSSI values reported by widely used 802.15.4 radios, such as the CC2420 and the AT86RF230, have profound impact on t...
