In this paper we present a comparative study on the use on event-based strategies for sampling and control of the level of a single tank. In the study a time-based PI control strategy is compared and contrasted with five combinations of pure event-based control approaches. In the event-based control strategies, the triggering of an event is the indicator to send a sample from the sensor or to calculate...
• characterize different drought types using a hydrological model and a drought index • identify ENSO effects during historical dry years • determine the effects of SRESa1b future scenario GCM ensembles • determine the usability of seasonal climate forecast data to reduce uncertainty in the outputs of GCMs. • quantify the effects of drought on agriculture using production data and compare it with...
This paper presents a methodology for the automatic detection of sub-optimal performance in UMTS networks based on drive-test measurements. The proposed methodology can be seen as a first step towards the more ambitious objective of implementing Self-Organising Network (SON) concepts in future wireless networks. In fact, the lessons learnt from real UMTS case studies enable the identification of key...
The selection of a particular neural network model belonging to the Pareto front is a problem that exists in all multi-objective algorithms. This paper proposes a novel solution to this problem based on a linear combination of the outputs of the two extremes in the Pareto front, which form an ensemble. The decision support TOPSIS method is used to determine which linear combination creates the best...
Among nonlinear-phenomena in propagation trough a nonlinear stack, switching describes change from an evanescent mode to a cavity stack mode. We use the analysis of Winful to extend previous results of a 1D nonlinear Stack.
We discuss a 3D Spherical Dielectric Photonic Crystal with a Metallic Core. Previous works have shown a distinctive transmission characterization for such a system. We show a continuous evolution that is explained by its dispersion relation.
