Distance function design and Lyapunov techniques for the stability of hybrid trajectories
J. J. Benjamin Biemond, W. P. Maurice H. Heemels, Ricardo G. Sanfelice +1
The comparison between time-varying hybrid trajectories is crucial for tracking, observer design and synchronisation problems for hybrid systems with state-triggered jumps. In this…
Constraints for the aperiodic O-mode streaming instability
M. Lazar, R. Schlickeiser, S. Poedts +2
In plasmas where the thermal energy density exceeds the magnetic energy density (), the aperiodic ordinary mode (O-mode) instability is driven by an excess of para…
Py3DFreeHandUS: a library for voxel-array reconstruction using Ultrasonography and attitude sensors
Davide Monari, Francesco Cenni, Erwin Aertbeliën +1
In medical imaging, there is a growing interest to provide real-time images with good quality for large anatomical structures. To cope with this issue, we developed a library that…
Herschel imaging of the dust in the Helix Nebula (NGC 7293)
G. C. Van de Steene, P. A. M. van Hoof, K. M. Exter +19
In our series of papers presenting the Herschel imaging of evolved planetary nebulae, we present images of the dust distribution in the Helix nebula (NGC 7293). Images at 70, 160,…
Surprising detection of an equatorial dust lane on the AGB star IRC+10216
S. V. Jeffers, M. Min, L. B. F. M. Waters +6
Understanding the formation of planetary nebulae remains elusive because in the preceding asymtotic giant branch (AGB) phase these stars are heavily enshrouded in an optically thic…
Gauged R-symmetry and its anomalies in 4D N=1 supergravity and phenomenological implications
I. Antoniadis, D. M. Ghilencea, R. Knoops
We consider a class of models with gauged U(1)_R symmetry in 4D N=1 supergravity that have, at the classical level, a metastable ground state, an infinitesimally small (tunable) po…
