Dependence of Crater Formation in Dry EDM on Electrical Breakdown Mechanism
(2016)Procedia CIRP ~ 18th CIRP Conference on Electro Physical and Chemical Machining (ISEM XVIII)The research effort in dry electrical discharge machining (DEDM) has increased during the last years. The process has advantages in comparison with EDM in oil-based dielectric media, such as low tool electrode wear, thin recast layers on the work piece surface and much more environmentally friendly conditions. However, the plasma-material surface interactions involved in dry EDM are not properly explained yet. Therefore, a characterization ...Conference Paper -
A Teaching System for Hands-on Quadcopter Control
(2019)IFAC-PapersOnLine ~ 12th IFAC Symposium on Advances in Control Education, ACE 2019. ProceedingsQuadcopters, popular in consumer and commercial applications, are a perfect testing ground for both basic and advanced control techniques. This makes them an ideal platform for offering experiment-based control courses. We present the software system developed to teach hands-on quadcopter control, that we have used to offer a short course to groups of 32 undergraduate electrical engineering students. Our system allows students to work ...Conference Paper -
On the optimal control problem for a class of monotone bilinear systems
(2016)Proceedings of the 22nd International Symposium on Mathematical Theory of Networks and SystemsWe consider a class of positive systems in which the control signal enters bilinearly with the state. Such dynamics arise naturally, for example, from modeling the evolutionary dynamics of HIV in the presence of drug therapy. For this class of system, we formulate an infinite horizon optimal control problem and show that the optimal control signal is constant over time. We further extend our results to the case of uncertain dynamics and ...Conference Paper -

GAMAS - A Generic And Multipurpose Archive System
(2019)PoS: Proceedings of Science ~ Proceedings of 36th International Cosmic Ray Conference (ICRC 2019)There exist many distributed storage systems that are mature and reliable. These systems are not fully adapted to the needs of an open astroparticle community mainly because they do not follow the Open Archival Information Systems (OAIS) standard. Moreover they require adaptations by each of the data centres at which they are installed. We introduce GAMAS, a novel distributed OAIS that tackles the problem of different technologies used ...Conference Paper -
Diamond sensors for future high energy experiments
(2016)Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment ~ Proceedings of the 10th International “Hiroshima” Symposium on the Development and Application of Semiconductor Tracking DetectorsWith the planned upgrade of the LHC to High-Luminosity-LHC [1], the general purpose experiments ATLAS and CMS are planning to upgrade their innermost tracking layers with more radiation tolerant technologies. Chemical Vapor Deposition CVD diamond is one such technology. CVD diamond sensors are an established technology as beam condition monitors in the highest radiation areas of all LHC experiments. The RD42-collaboration at CERN is leading ...Conference Paper -
Measurement of anisotropic flow in XeXe collisions at 5.44 TeV with the CMS experiment
(2019)Nuclear Physics A ~ The 27th International Conference on Ultrarelativistic Nucleus-Nucleus Collisions (Quark Matter 2018)New measurements of anisotropic flow in XeXe collisions at a center-of-mass energy of 5.44 TeV per nucleon pair, collected by the CMS experiment at the LHC, are presented. The ν2, ν3 and ν4 Fourier coefficients of the anisotropic azimuthal distribution are obtained employing three different analysis techniques: two-particle correlations, the scalar product method, and multiparticle cumulants, which have different sensitivities to non-flow ...Conference Paper -
