Geometric and Signal Strength Dilution of Precision (DoP)Wi-Fi
Soumaya Zirari, Philippe Canalda, Francois Spies
The democratization of wireless networks combined to the emergence of mobile devices increasingly autonomous and efficient lead to new services. Positioning services become overcro…
Radially Polarized Conical Beam from an Embedded Etched Fiber
Djamel Kalaidji, Michel Spajer, Nadège Marthouret +1
We propose a method for producing a conical beam based on the lateral refraction of the TM01 mode from a two-mode fiber after chemical etching of the cladding, and for controlling…
Kinematics at the Edge of the Galactic Bulge: Evidence for Cylindrical Rotation
Christian D. Howard, R. Michael Rich, Will Clarkson +9
We present new results from BRAVA, a large scale radial velocity survey of the Galactic bulge, using M giant stars selected from the Two Micron All Sky Survey catalogue as targets…
Generalized composition law from 2x2 matrices
R. Giust, J. -M. Vigoureux, J. Lages
Many results that are difficult can be found more easily by using a generalization in the complex plane of Einstein's addition law of parallel velocities. Such a generalization is…
Characterization of the thermo-mechanical behaviour of Hemp fibres intended for the manufacturing oh high performance composites
Vincent Placet
In this paper, the thermo-mechanical behaviour of hemp fibres (Cannabis sativa L.) is investigated using a Dynamic Mechanical Analyser. Experiments are performed at a frequency of…
A New Characterisation of Idempotent States on Finite and Compact Quantum Groups
Uwe Franz, Adam Skalski
We show that idempotent states on finite quantum groups correspond to pre-subgroups in the sense of Baaj, Blanchard, and Skandalis. It follows that the lattices formed by the idemp…
