Properties and nature of Be stars 30. Reliable physical properties of a semi-detached B9.5e+G8III binary BR CMi = HD 61273 compared to those of other well studied semi-detached emission-line binaries
Reliable determination of the basic physical properties of hot emission-line binaries with Roche-lobe filling secondaries is important for developing the theory of mass exchange in binaries. It is a very hard task, however, which is complicated by the pres ...
EDP Sciences2015Gravitational tides and dwarf spheroidal galaxies
Pascale Jablonka, Yves Revaz, Matthew Luke Nichols
The effect of the local environment on the evolution of dwarf spheroidal galaxies is poorly understood. We have undertaken a suite of simulations to investigate the tidal impact of the Milky Way on the chemodynamical evolution of dwarf spheroidals that res ...
EDP Sciences2014Surpassing Fundamental Limits of Oscillators Using Nonlinear Resonators
Luis Guillermo Villanueva Torrijo
In its most basic form an oscillator consists of a resonator driven on resonance, through feedback, to create a periodic signal sustained by a static energy source. The generation of a stable frequency, the basic function of oscillators, is typically achie ...
American Physical Society2013Self-shaping attractors for coupled limit cycle oscillators
Max-Olivier Hongler, Philippe Blanchard, Julio Rodriguez
We consider a complex network of N diffusively coupled stable limit cycle oscillators. Each individual system has its own set of local parameters Λ, characterizing its frequencies and the shape of limit cycle. The Λ are allowed, thanks to appropriate inter ...
Springer2013An Artificial Muscle Ring Oscillator
Dielectric elastomer artificialmuscles have great potential for the creation of novel pumps, motors, and circuitry. Control of these devices requires an oscillator, either as a driver or clock circuit, which is typically provided as part of bulky, rigid, a ...
2012OPTIMIZATION OF THE POSITION OF THE RADIAL LOOP PICKUPS IN THE CERN PS
A part of the beam losses at transition crossing of high intensity beams in the CERN PS have been attributed to an excursion of the closed orbit. The orbit jump occurs simultaneously with the jump of the transition energy triggered by pulsed quadrupoles. I ...
2010Parametric Resonance in Time-Dependent Networks of Hopf Oscillators
Max-Olivier Hongler, Julio Rodriguez
We study a collection of limit cycle oscillators with different frequencies interacting via networks. With static networks, our specific class of models produces a frequency learning mechanism leading the collection of oscillators to ultimately adopt a sin ...
2010Electrostatic and magnetic transport of energetic ions in turbulent plasmas
Analytical and numerical work is used in tandem to address the problem of turbulent transport of energetic ions in magnetized plasmas. It is shown that orbit averaging is not valid under rather generic conditions, and that perpendicular decorrelation effec ...
American Physical Society2009Adaptive Frequency Oscillators and Applications
Auke Ijspeert, Jonas Buchli, Ludovic Righetti
In this contribution we present a generic mechanism to transform an oscillator into an adaptive frequency oscillator, which can then dynamically adapt its parameters to learn the frequency of any periodic driving signal. Adaptation is done in a dynamic way ...
2009Frequency analysis with coupled nonlinear oscillators
Auke Ijspeert, Jonas Buchli, Ludovic Righetti
We present a method to obtain the frequency spectrum of a signal with a nonlinear dynamical system. The dynamical system is composed of a pool of adaptive frequency oscillators with negative mean-field coupling. For the frequency analysis, the synchronizat ...
