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 ...

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 ...
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 ...
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 ...
Goal of the Study: to achieve comparable reliability and reproducibility of the thermistor characteristics with LTCC as with standard alumina substrates. ...
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 ...
This work deals with the concept of active materials with variable acoustic properties, dedicated to room acoustics applications. This concept is based on an acoustic impedance active control principle by hybrid motionnal feedback, applied on an electroaco ...
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 ...
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 ...
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 ...
