TL;DR: A second-order sliding mode strategy to control the breathing subsystem of a polymer electrolyte membrane fuel cell stack for transportation applications is presented and exhibits good dynamic characteristics, being robust to uncertainties and disturbances.
Abstract: A second-order sliding mode strategy to control the breathing subsystem of a polymer electrolyte membrane fuel cell stack for transportation applications is presented. The controller is developed from a design model of the plant derived from open literature, and well suited for the design of second-order sliding mode strategies. Stability issues are solved using a super twisting algorithm. The resulting approach exhibits good dynamic characteristics, being robust to uncertainties and disturbances. Simulations results are provided, showing the feasibility of the approach.

TL;DR: The SemEval-2010 task on coreference resolution in multiple languages as mentioned in this paper evaluated and compared automatic resolution systems for six different languages (Catalan, Dutch, English, German, Italian and Spanish) in four evaluation settings and using four different metrics.
Abstract: This paper presents the SemEval-2010 task on Coreference Resolution in Multiple Languages. The goal was to evaluate and compare automatic coreference resolution systems for six different languages (Catalan, Dutch, English, German, Italian, and Spanish) in four evaluation settings and using four different metrics. Such a rich scenario had the potential to provide insight into key issues concerning coreference resolution: (i) the portability of systems across languages, (ii) the relevance of different levels of linguistic information, and (iii) the behavior of scoring metrics.

TL;DR: It is proved that any triangulation of a set of n points in general position contains at least $\lceil (n-4)/2 \rceil$ edges that can be flipped.
Abstract: In this paper we study the problem of flipping edges in triangulations of polygons and point sets. One of the main results is that any triangulation of a set of n points in general position contains at least $\lceil (n-4)/2 \rceil$ edges that can be flipped. We also prove that O(n + k 2 ) flips are sufficient to transform any triangulation of an n -gon with k reflex vertices into any other triangulation. We produce examples of n -gons with triangulations T and T' such that to transform T into T' requires Ω(n 2 ) flips. Finally we show that if a set of n points has k convex layers, then any triangulation of the point set can be transformed into any other triangulation using at most O(kn) flips.

TL;DR: This note studies the efficiency of the emergence of social conventions in complex networks, that is, how fast conventions are reached and finds out that scale-free graphs make the system as efficient as fully connected graphs.
