DEVELOPING A RELIABLE CAPTURE SYSTEM FOR CLEANSPACE ONE

Pierre-Alain Mäusli, Muriel Richard, Camille Sébastien Pirat, Régis Voillat, Timothée Robert Sophus Frei, Xavier Collaud, Bastien Gorret, Michel Lauria

The objectives of the CleanSpace One mission are to raise the awareness of the orbital debris problem, develop and test technologies for non-cooperative rendezvous and as a demonstration, de-orbit the SwissCube satellite. Within this project and over the l ...

An advection-diffusion model for cross-field runaway electron transport in perturbed magnetic fields

Joan Decker

Disruption-generated runaway electrons (RE) present an outstanding issue for ITER. The predictive computational studies of RE generation rely on orbit-averaged computations and, as such, they lack the effects from the magnetic field stochasticity. Since st ...

Orbital textures and charge density waves in transition metal dichalcogenides

Helmuth Berger

Low-dimensional electron systems, as realized in layered materials, often tend to spontaneously break the symmetry of the underlying nuclear lattice by forming so-called density waves(1); a state of matter that at present attracts enormous attention(2-6). ...

GNSS PERFORMANCES FOR MEO, GEO AND HEO

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Global Navigation Satellite Systems (GNSSs) such as GPS, GLONASS, and the future Galileo and BeiDou, have demonstrated to be a valid and efficient system for various space applications in Low Earth Orbit (LEO), such as spacecraft orbit and attitude determi ...

This paper proposes a solution to perform active debris removal with a cost effective microsatellite. A complex aspect of debris removal in space is the detection and positive identification of the debris, medium to close approach as well as the orbital re ...

MEMS Inertial Sensor to Measure the Gravity Gradient Torque in Orbit

Kaustav Ghose

Since the dawn of the Space Age, over six thousand satellites have been launched into Earth orbit. The function of determining the orientation of a satellite in orbit, so that it can point its antennas and instruments in the required direction is known as ...

Periodic orbits near onset of chaos in plane Couette flow

Tobias Klaus Kreilos

We track the secondary bifurcations of coherent states in plane Couette flow and show that they undergo a periodic doubling cascade that ends with a crisis bifurcation. We introduce a symbolic dynamics for the orbits and show that the ones that exist fall ...

Affine-invariant properties are an abstract class of properties that generalize some central algebraic ones, such as linearity and low-degree-ness, that have been studied extensively in the context of property testing. Affine invariant properties consider ...

Distribution of periodic torus orbits and Duke's theorem for cubic fields

Philippe Michel

We study periodic torus orbits on spaces of lattices. Using the action of the group of adelic points of the underlying tori, we define a natural equivalence relation on these orbits, and show that the equivalence classes become uniformly distributed. This ...

In the context of metric perturbation theory for nonspinning black holes, extreme mass ratio binary systems are described by distributionally forced master wave equations. Numerical solution of a master wave equation as an initial boundary value problem re ...
