Using Coherent Averaging with time-varying conditions to remove room reverberation from transducer measurements

François Aballéa

Abstract: The use of coherent averaging in building acoustics is familiar to those who use deterministic signals (e.g. MLS) as the basis for their measurements. The primary concern is to achieve a sufficient signal to noise ratio so that results relate to ...

A preliminary study of an isodynamic transducer for use in active acoustic materials

Hervé Lissek

Active control of the acoustic impedance of walls in rooms allows fine control of the reverberation in auditoria. Such active materials may use locally reacting cells comprising a transducer connected to an electronic control circuit. In this paper, a simp ...

High Affinity Molecules Disrupting GRB2 Protein Complexes as a Therapeutic Strategy for Chronic Myelogenous Leukaemia

A review. Chronic myelogenous leukemia (CML) is one of the most intensively studied human malignancies. It has been the focus of major efforts to develop potent drugs for several decades, but until recently cure rates remained low. A breakthrough in CML th ...

Onboard Measurements of Pressure and Strain Fluctuations in a Model of low Head Francis Turbine. Part 1 : Instrumentation

François Avellan, Mohamed Farhat, Michel Couston, Silvia Natal

In this first part of a 2 papers series, we present the experimental procedure for onboard measurement of pressure and strain fluctuation in a model of low head Francis turbine. 28 miniature pressure sensors are fitted in the pressure and suction sides of ...

Prolactin signaling and Stat5: going their own separate ways?

Cathrin Brisken, Ayyakkannu Ayyanan

Miyoshi et al. compared the role of the prolactin receptor (PrlR) and its downstream mediator, the signal transducer and activator of transcription 5 (Stat5), in mammary epithelial cells in vivo by studying PrlR-/- and Stat5ab-/- mouse mammary epithelial t ...

Sensorless position estimation of linear voice-coil transducers

Yves Perriard, Jan Persson, Christian Blanc

In this paper, a method for sensorless position estimation of linear transducers at standstill is suggested. The method makes use of current pulses, which is a common sensorless starting technique for 3-phase synchronous motors. Most transducers possess ho ...

Synthesis of lead nickel niobate-lead zirconate titanate solid solutions by a B-site precursor method

Nava Setter, Dragan Damjanovic

A modified processing method for lead nickel niobate-lead zirconate titanate (Pb(Ni1/3Nb2/3)O-3-Pb(Zr,Ti)O-3, PNN-PZT) solid solutions is presented. This method is based on the high-temperature synthesis of a precursor that contains all the B-site cations ...

Compact fast-steering tip/tilt laser scanner for high power material processing applications

Moustapha Hafez

The common configuration for deflecting laser beams in two dimensions is based on two single-axis galvanometric scanners placed perpendicular to each other. Over recent years, these fast scanners have proved to be both very reliable and very accurate. They ...
