An analysis of a gyro-free inertial system for INS/GNSS navigation

Although the concept of determining angular velocity out of the readings of multiple, displaced accelerometers is not new, apparently it has not yet matured into practical technologies. A new generation of low-cost MEMS accelerometers, which is expected to ...

MEMS Tunable Mid-Infrared Plasmonic Spectrometer

Matthias Imboden, Shyamsunder Erramilli

We present a microelectromechanical systems (MEMS) tunable metamaterial, Fabry-Perot interferometer with a widely tunable mid-infrared response. An array of subwavelength holes in a gold film is suspended above a gold reflector, forming an interferometer c ...

Structured sparsity through reweighting and application to diffusion MRI

Jean-Philippe Thiran, Yves Wiaux, Alessandro Daducci, Anna Auria Rasclosa

We consider the problem of multiple correlated sparse signals reconstruction and propose a new implementation of structured sparsity through a reweighting scheme. We present a particular application for diffusion Magnetic Resonance Imaging data and show ho ...

Isolator-free unidirectional thulium-doped fiber laser

Camille Sophie Brès, Svyatoslav Kharitonov

We report the first demonstration of a unidirectional, isolator-free 2-mmthulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output ...

Slow Light in Optical Fibers: State-of-the-Art and Perspectives 10 Years After the First Demonstration

Luc Thévenaz

The possibility to directly realize all-optical delay lines in optical fibers has triggered efforts of research during the past decade, with few practical outcomes. The reason is fundamental, caused by the unescapable relation between delay and distortion. ...

Dominant speed factors of active set methods for fast MPC

Colin Neil Jones

The paper presents a review of active set (AS) algorithms that have been deployed for implementation of fast model predictive control (MPC). The main purpose of the survey is to identify the dominant features of the algorithms that contribute to fast execu ...

Design and Fabrication of a Prototype Actuator for Fourier Transform Interferometry

Yves Bellouard

The design, fabrication and characterisation of an uniaxial scanning mirror component for interferometry applications is presented. The device is fabricated in fused silica by means of femtosecond laser irradiation and a selective etching step. The fabrica ...

Kinematic Batch Calibration for Legged Robots

Roland Siegwart, Marco Hutter

This paper introduces a novel batch optimization based calibration framework for legged robots. Given a nondegenerate calibration dataset and considering the stochastic models of the sensors, the task is formulated as a maximum likelihood problem. In order ...

Quasi-static monotonic and cyclic tests on composite spandrels

Katrin Beyer, Alessandro Dazio

In modern unreinforced masonry (URM) walls, the vertical piers are connected at the storey levels by reinforced concrete (RC) ring beams or RC slabs. Particularly, in the outer walls, the spandrel element also includes a masonry spandrel on top of the RC b ...

Modelling of spandrel elements in URM structures with RC slabs or ring beams

Katrin Beyer, Alessandro Dazio

In many unreinforced masonry (URM) buildings reinforced concrete (RC) slabs or ring beams maintain the integrity of the building when subjected to seismic loading and redistribute forces between different URM piers. In addition, RC slabs and ring beams con ...
