Diophantine properties of nilpotent Lie groups

A finitely generated subgroup F of a real Lie group G is said to be Diophantine if there is beta > 0 such that non-trivial elements in the word ball B-Gamma(n) centered at 1 is an element of F never approach the identity of G closer than broken vertical ba ...

On-chip NIR optical spectrometer based on polymeric waveguide and metallic nano-structures

Hans Peter Herzig, Toralf Scharf, Maurine Malak Karam Awadallah

In this work, we report about optical spectrometry using gold nano-structures printed on a polymer based integrated optical waveguide. The optical waveguide is a single mode buried waveguide, having dimensions of 3x2.2µm 2 . It is made from a combination o ...

Nonlinearity in nanomechanical cantilevers

Luis Guillermo Villanueva Torrijo

Euler-Bernoulli beam theory is widely used to successfully predict the linear dynamics of micro-and nanocantilever beams. However, its capacity to characterize the nonlinear dynamics of these devices has not yet been rigorously assessed, despite its use in ...

Empirical and analytical analyses of laboratory granular flows to investigate rock avalanche propagation

Vincent Labiouse, Irene Manzella

Laboratory experiments which consist of releasing dry rigid non-cohesive grains or small bricks on an unconfined chute have been designed to investigate rock avalanche propagation mechanisms and to identify parameters influencing their deposit characterist ...

Morphology and stability of Au nanoclusters in HOPG nanopits of well-defined depth

Wolfgang Harbich, Michael Hugentobler, Simon Bonanni

Gold nanoparticles with a diameter comprised between 4 and 6 nm are stabilized in nanosized pits of well defined depth in highly oriented pyrolytic graphite (HOPG). These pits are produced by creation of artificial defects, followed by etching under a cont ...

Non-axis-symmetrical punching shear around internal columns of RC slabs without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar, Luca Tassinari

Most analytical approaches and available test data for punching shear in flat slabs assume axis-symmetrical conditions, which seems realistic for representing slabs supported on columns equally spaced in both orthogonal directions. However, in practice, th ...

A Polyvinylidene fluoride (PVDF) based bimorph actuator for high speed laser beam manipulation

Hannes Bleuler, Reymond Clavel, Ricardo Pérez Suárez

High-speed laser manipulation is a key technology in applications such as fast optical switches for coupling light into optical fibres, 2D beam steering for optical scanners, laser printers or 2D sensors. A novel design of a Polyvinylidene Fluoride (PVDF) ...
