        In-process grinding monitoring through acoustic emission 

        Universidade Estadual Paulista (UNESP); ABCM (2006-01-01)
        This work aims to investigate the efficiency of digital signal processing tools of acoustic emission signals in order to detect thermal damages in grinding processes. To accomplish such a goal, an experimental work was ...

        Species Richness drives the Use of Acoustic Space 

        Hernandez Serna, Andres; Mitchell Aide, Thomas (Consejero) (2017)

        In-process grinding monitoring through acoustic emission 

        Aguiar, Paulo R.; Serni, Paulo J. A.; Dotto, Fábio R. L.; Bianchi, Eduardo C. (2014)

        Energy method to calculate the density of liquids using ultrasonic reflection techniques 

        Universidade Estadual Paulista (UNESP) (2001-12-01)
        In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...

        Energy method to calculate the density of liquids using ultrasonic reflection techniques 

        Higuti, Ricardo Tokio; Montero de Espinosa, Francisco R.; Adamowski, Julio Cezar (2014)

        Production grinding burn detection using acoustic emission and electric power signals 

        Universidade Estadual Paulista (UNESP) (1999-12-01)
        This work uses a monitoring system based on a PC platform, where the acoustic emission and electric power signals generated during the grinding process are used to investigate superficial burning occurrence in a surface ...

        Components of the acoustic swallowing signal: Preliminary study 

        Universidade de São Paulo (USP); Universidade Estadual Paulista (UNESP) (2012-12-01)
        Purpose: To analyze the components of the acoustic signal of swallowing using a specific software. Methods: Fourteen healthy subjects ranging in age from 20 to 50 years (mean age 31±10 years), were evaluated. Data collection ...

        INVESTIGATION OF ACOUSTIC SIGNALS AS A TOOL FOR CHARACTERIZING SPOUTED BED DYNAMICS 

        OLIVEIRA, W. P.; GRACE, J. R.; LIM, C. J.; HODGSON, M. R. (JOHN WILEY & SONS INC, 2009)
        The feasibility of characterizing the dynamics of a spouted bed based on acoustic emission (AE) signals is evaluated. Acoustic emission signals were measured in a semi-cylindrical Plexiglas column of diameter 150 mm and ...

        Digital signal processing of acoustic emission signals using power spectral density and counts statistic applied to single-point dressing operation 

        Universidade Estadual Paulista (UNESP) (Inst Engineering Technology-iet, 2017-08-01)
        Dressing is an important operation for the grinding process. Its goal is to recondition the wheel tool to re-establish its cutting characteristics, owing to the wear produced after successive passes. Monitoring systems ...

        The dynamic behaviour of a buried water pipe and its effect on leak location using acoustic methods 

        University of Southampton; Universidade Estadual Paulista (UNESP); South Staffs Water plc; Hydrosave Ltd. (2013-09-16)
        Leakage in buried pipes is one of the main concerns for water companies due to the scarcity of potable water sources. Older metallic pipelines have been replaced by plastic pipes in such systems, which makes it more difficult ...
