Dr. Luis Elvira Segura (CSIC - Spain) will visit the Laboratory of Ultrasound (LUS)-Unesp for a period of one year. Dr. Elvira has a large experience in the measurement of properties of liquids using ultrasound, including theoretical modeling, design and implementation of dedicated instrumentation and analysis of experimental data. He will have an important role in a research project that…
The main objecive of this research project is the development of a high-frequency ultrasonic cell for measurement of properties of liquids with the following characteristics: high-frequency pulsed operation (20 to 100 MHz), high thermal stability (0.01oC), small volumes (0.5 to 3.0 ml), employing disposable/sterilizable cuvettes. The use of wideband and high-frequency transducers will all…
The visiting professor, Dr. Francisco Montero de Espinlisa (CSIC - Spain) will visit two laboratories: LUS - Unesp (Ultrasound Laboratory, Unesp, Ilha Solteira) and LUS - USP (Ultrasound Laboratory, USP Polytechnic School, São Paulo). Dr. Montero de Espinosa is an experienced researcher (theory and practice) in the areas of design, manufacturing and tests of ultrasonic arrays and transduc…

In ultrasonic spectroscopy, the propagation velocity and attenuation coefficient of an acoustic wave that propagates through a sample are measured as a function of frequency. From these parameters, other properties of the sample can be indirectly inferred, such as compressibility, elastic constants, concentration/composition, adulterations, etc. One acoustic method for measuring propertie…
This project has the objective to develop a temperature control system using Peltier effect cells, which will be used for ultrasound experiments that demand controlled temperature. A styrofoam box will be used as thermal recipient, where temperature sensors and Peltier cells will be installed. A signal conditioning circuit will be implemented, whose outputs are connected to the analog-dig…
The objective of this work is to consolidate the research on beamforming for ultrasonic non-destructive testing at the Laboratory of Ultrasound of the Faculdade de Engenharia de Ilha Solteira - UNESP. The emphasis will be on techniques using digital signal processing and the phase of the signals as additional information to the amplitude by theoretical analysis, simulation and experimenta…

This plan proposes a research internship in the Grupo de Evaluación por Ultrasonidos of the Centro de Acústica Aplicada y Evaluación No Destructiva - Consejo Superior de Investigaciones Científicas, in the area of acoustic imaging with arrays. Specifically, the topic of interest is in image formation/compounding techniques with linear and/or two-dimensional sparse arrays. The use of spars…
It is proposed an internship at University of Limerick, Department of Electronic and Computer Engineering, Optical Communications Research Group, on vibration measurement using optical techniques. Laser Doppler Vibrometry (LDV) is based on interference of two laser beams, being a kind of optical interferometry. One of the beams is reflected by a vibrating object and is therefore Doppler s…
