We formulate fuel optimal conflict free aircraft trajectory planning as a hybrid optimal control problem. The discrete modes of the hybrid system capture the air traffic procedures for conflict resolution, e. g., speed and turn advisories. In order to solv ...
Research on conflict prevention has mainly focused on the causes of war and post-conflict reconstruction. Our knowledge on how civilians manage to contain violence in unstable and conflict environments is, however, very limited. This article aims to unders ...
This article presents the gradual liberalization of European air transport, especially its most recent problems in the case of the Single European Sky (SES). Indeed, after successfully liberalizing airlines and, to a certain extent, airports, the European ...

The goal of multi-objective query optimization (MOQO) is to find query plans that realize a good compromise between conflicting objectives such as minimizing execution time and minimizing monetary fees in a Cloud scenario. A previously proposed exhaustive ...

Multi-channel receive array rf-coils have become widely available for fMRI. The improved SNR and possibility of acquisition acceleration through parallel imaging are especially beneficial for high-resolution studies. In this study, an 8-channel and a 32-ch ...
In this paper, we propose a method for modeling trajectory patterns with both regional and velocity observations through the probabilistic topic model. By embedding Gaussian models into the discrete topic model framework, our method uses continuous velocit ...
This report presents some approaches to modelize urban energy systems. More precisely, as a first step, a clear definition of what is an urban energy system model is exposed before listing the main tech- niques of modelization. With the goal to run a case ...
A coordinated field experiment, the Eastern Pacific Emitted Aerosol Cloud Experiment (E-PEACE) campaign, in which the effects of well-defined aerosol perturbations on marine stratocumulus clouds were probed via in situ aircraft and satellite observations. ...
