Numerical modeling of double-layered piezoelectric transducer systems using a high-order discontinuous Galerkin method
A high-order discontinuous Galerkin finite element method, on triangular elements, is used to model piezoelectric systems. Non-destructive testing problems are Studied. In particular, flex circuit transducer designs which can be used to obtain information ...
PERGAMON-ELSEVIER SCIENCE LTD2008Models for piezoelectric sensor-actuator systems
The miniaturization trend in industry requires micro devices for handling and sensing in a micro environment. As the size of the handled objects decreases and their fragility increases, the demand for sensors with higher force sensitivity and resolution gr ...
EPFL2007Intensity based quantification of fast retinal blood flow in 3D via high resolution resonant Doppler spectral OCT - art. no. 66270J
Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely, Cédric Blatter
Resonant Doppler Fourier Domain Optical Coherence Tomography is a functional imaging modality for quantifying fast tissue flow. The method profits from the effect of interference fringe blurring in spectrometer-based FDOCT in the presence of sample motion. ...
Spie-Int Soc Optical Engineering, Po Box 10, Bellingham, Wa 98227-0010 Usa2007Weak solution of a stationary convection-diffusion model describing binary alloy solidification processes
Our goal is to study the existence of weak solution for the stationary system of equations describing the solidification process of a binary alloy confined in a bounded regular domain in R-3 and having mixed boundary conditions. (c) 2005 Elsevier Ltd. All ...
2005Piezoelectric actuator with passive gap for push-pull motion
Jean-Marc Breguet, Arvid Bergander
The invention relates to a Stick-Slip piezoelectric actuator comprising a piezoelectric element with active zones and passive zones, said active zones being transversally deformable by applying different voltages, said passive zones not being actively defo ...
2004Energy Consumption of Piezoelectric Actuators for Inertial Drives
Jean-Marc Breguet, Walter Driesen
Energy consumption is a major issue for inertial drives with piezoelectric actuators that are integrated in autonomous devices. This paper discusses some theoretical aspects and some experimental results about the energy consumption of inertial drives with ...
2003Flow Investigation in a Francis Draft Tube : the Flindt Project
The flow investigation in a elbow draft tube is presented. After a review of the existing works related to the flow analysis of such component, the need of an experimental validation of the CFD tools is discussed with respect the practical interest of impr ...
