Modeling and analysis of miniaturized magnetorheological valve for fluidic actuation

Fluidic actuation enables movement in a wide range of mechanical systems, from simple laboratory devices to more complex industrial machinery. Fluids are used to generate motion of mechanical pieces. The term "fluids" encompasses two types of technologies: ...

Cooperative Multi-Robot Systems for Aquatic Environmental Sensing

Anwar Ahmad Quraishi

Bringing advantages of parallelism and robustness, distributed robotic systems have become an active subject of research since many years. Yet, the progress in that direction with Autonomous Underwater Vehicles (AUVs) has been limited. This project aims at ...

Gradient expansion formalism for magnetogenesis in the kinetic coupling model

Oleksandr Sobol

In order to describe magnetogenesis during inflation in the kinetic coupling model, we utilize a gradient expansion which is based on the fact that only long-wavelength (superhorizon) modes undergo amplification. For this purpose, we introduce a set of fun ...

On Cyclic Dependencies and Regulators in Time-Sensitive Networks

Jean-Yves Le Boudec, Ludovic Bernard Gérard Thomas

For time-sensitive networks, as in the context of IEEE TSN and IETF Detnet, cyclic dependencies are associated with certain fundamental properties such as improving availability and decreasing reconfiguration effort. Nevertheless, the existence of cyclic d ...

A new bioinspired method for pressure and flow sensing based on the underwater air-retaining surface of the backswimmer Notonecta

Goran Lovric

In technical systems, static pressure and pressure changes are usually measured with piezoelectric materials or solid membranes. In this paper, we suggest a new biomimetic principle based on thin air layers that can be used to measure underwater pressure c ...

Compact Drop-on-Demand Apparatus Using Light Actuation Through Optical Fibers

Demetri Psaltis, Christophe Moser, Paul Delrot

A drop delivery system comprising a light source; an optical waveguide bringing light from the light source; and a liquid supplying means configured to bring a liquid at a tip of the optical waveguide, wherein the light source and the optical waveguide are ...

Idealized digital models for conical reed instruments, with focus on the internal pressure waveform

Two models for the generation of self-oscillations of reed conical woodwinds are presented. The models use the fewest parameters (of either the resonator or the exciter), whose influence can be quickly explored. The formulation extends iterated maps obtain ...

Integrated SMD pressure/flow/temperature multisensor for compressed air in LTCC technology: Thermal flow and temperature sensing

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Nicolas Craquelin, Jean-Bastien Coma

In this work, we present and analyse the flow-sensing part of a recently-developed multisensor in LTCC (low- temperature co-fired ceramic) technology; this device integrates flow / pressure / temperature sensing and is designed for diagnostics monitoring o ...
