One- and two-dimensional UVP velocity sampling in a cuboidal basin subject to in- and outflow sequences

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of an experimental study on the influence of in- and outflow sequences on flow patterns and suspended sediment behavior in reservoirs, flow fields and inflowing jet were sampled by Ultrasonic Velocity Profilers (UVP). The laboratory set-up ...

Multiresolution Information Mining for Pavement Crack Image Analysis

Rafael Eduardo Carrillo Rangel

Empirical mode decomposition (EMD) is a multiresolution data analysis method recently developed to cater to the inherent nonstationarity in real-world signals. A two-dimensional (2D) extension of EMD is used in this paper as a pavement distress image analy ...

Study of polyvinylidene fluoride (PVDF) based bimorph actuators for laser scanning actuation at kHz frequency range

Hannes Bleuler, Ricardo Pérez Suárez

This work focuses on some promising applications of polyvinylidene fluoride (PVDF) based bimorph actuators in microengineering. The actuator of several centimeters in length and 100 mu m in thickness takes advantage of the structural and electromechanical ...

A speckle-based CMOS sensor array for arbitrary surface movement detection

Pierre-André Farine, Chao Wang, Steve Tanner

The paper presents a CMOS sensor array for the detection of speckle movements, for applications requiring accurate movement tracking of arbitrary surfaces. The array is made of eight sensors incorporating each a spatial comb filter with a pitch of 2.8μm so ...

Robust Controller Design by Convex Optimization based on Finite Frequency Samples of Spectral Models

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not guaranteed for the frequencies between the frequency samples. In this paper, all possible ...

A 16-bit, 150-μW, 1-kS/s ADC with hybrid incremental and cyclic conversion scheme

Pierre-André Farine, Luca Rossi, Steve Tanner

This paper presents the design, realization and characterization of a new hybrid A/D converter based on a combined incremental and cyclic conversion. The proposed implementation offers a configurable resolution, and permits to share the same hardware for t ...

Music Onset Detection Based on Resonator Time Frequency Image

Marco Mattavelli, Giorgio Zoia, Ruohua Zhou

This paper describes a new method for music onset detection. The novelty of the approach consists mainly of two elements: the time–frequency processing and the detection stages. The resonator time frequency image (RTFI) is the basic time–frequency analysis ...
