Silva, Carlos A.M.; Saraiva, Samuel V.; Bonetti, Darlan; Higuti, Ricardo T. [UNESP]; Cunha, Rosiane L.; Pereira, Luiz O.V.; Silva, Flavio V.Made available in DSpace on 2022-04-28T19:47:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-28; Ultrasonic spectroscopy has a great potential to measure the particle sizes in suspensions and emulsions of many industrial sectors. However, one significant challenge is measuring particle sizes in a broader range and concentrated systems due to the lack of theoretical models covering large particle wa...

Silva, Carlos A. M.; Saraiva, Samuel; Bonetti, Darlan; Higuti, Ricardo T. [UNESP]; Cunha, Rosiane L.; Pereira, Luiz O.; Silva, Flavio; Fileti, Ana M. F.Made available in DSpace on 2020-12-10T17:40:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-10-05; Petrobras; ANP; Ultrasonic spectroscopy is a technique that often has been used for measuring the particle size distribution in suspensions and emulsions. The ability to analyze concentrated heterogeneous systems and optically opaque samples, without the need for dilution, is the major advantage over al...

Lamb wave detection with a fiber optic angular displacement sensor
Garcia, Marlon R. [UNESP]; Sakamoto, Joao M. S.; Higuti, Ricardo T. [UNESP]; Kitano, Claudio [UNESP]; Kalinowski, H. J.; Fabris, J. L.; Bock, W. J.Made available in DSpace on 2018-11-26T16:17:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-01-01; In this work we show that the fiber optic angular displacement sensor is capable of Lamb wave detection, with results comparable to a piezoelectric transducer. Therefore, the fiber optic sensor has a great potential to be used as the Lamb wave ultrasonic receiver and to perform non-destructive and non-c...
