Modal behavior of a reduced scale pump-turbine impeller. Part 1: Experiments

François Avellan, Mohamed Farhat, Eduard Egusquiza

An experimental investigation has been carried out to quantify the effects of surrounding fluid on the modal behavior of a reduced scale pump-turbine impeller. The modal properties of the fluid-structure system have been obtained by Experimental Modal Anal ...

Multi-signal extension of adaptive frequency tracking algorithms

Jean-Marc Vesin, Yann Prudat

Adaptive tracking of sinusoidal signal components with time-varying amplitudes and frequencies presents a great interest in many engineering applications. In many cases, the frequency components of interest are present in more than one signal. So we propos ...

The dynamical response properties of neocortical neurons to temporally modulated noisy inputs in vitro

Michele Giugliano

Cortical neurons are often classified by current-frequency relationship. Such a static description is inadequate to interpret neuronal responses to time-varying stimuli. Theoretical studies suggested that single-cell dynamical response properties are neces ...

Dynamic Measurement of Room Impulse Responses using a Moving Microphone

Martin Vetterli, Luciano Sbaiz, Thibaut Ajdler

A novel technique for the recording of large sets of room impulse responses or head-related transfer functions is presented. The technique uses a microphone or a loudspeaker moving with constant speed. Given a setup (e.g. length of the room impulse respons ...

A completely scalable lumped-circuit model for horizontal and vertical HALL devices

Radivoje Popovic, Predrag Drljaca

A completely scalable lumped-circuit model for horizontal and vertical HALL devices is presented therein that can be efficiently implemented in SPICE-like EDA simulators. The model has been employed for the quantitative analysis of. a) geometrical, b) temp ...

Modal Response of Hydraulic Turbine Runners

François Avellan, Eduard Egusquiza

The mechanical design of hydraulic turbines is conditioned by the dynamic response of the runner that is usually estimated by a computational model. Nevertheless, the runner has complex boundary conditions that are difficult to include in the computational ...

Persistent clusters in lattices of coupled nonidentical chaotic systems

Martin Hasler, Igor Belykh

Two-dimensional (2D) lattices of diffusively coupled chaotic oscillators are studied. In previous work, it was shown that various cluster synchronization regimes exist when the oscillators are identical. Here, analytical and numerical studies allow us to c ...

, ,

An experimental investigation on Francis turbines suffering from inlet cavitation erosion on the runner blades has permitted to assess several aspects of the actual cavitation erosion detection and prediction methods based on vibrations. Detection tests in ...

International Association For Hydraulic Research2002

In this study, chaotic wandering phenomenon observed in simple coupled chaotic circuits is modeled by Markov chains. As coupling parameter increases, the solution of the coupled chaotic circuits starts to wander chaotically over 6 different phase states wh ...

Modeling diversity by strange attractors with application to temporal pattern recognition

Oscar De Feo

This thesis belongs to the general discipline of establishing black-box models from real-word data, more precisely, from measured time-series. This is an old subject and a large amount of papers and books has been written about it. The main difficulty is t ...
