Numerical study of the spectral 3-D Green's function singularities for piezoelectric SAW components
(2005)
This article deals with the numerical study of the singularities appearing in the spectral 3-D Green's function associated with the piezoelectric surface acoustic wave components (so-called SAW components). These electrical ...
Saddle-Node Bifurcations and Design Parameters for Single-Axis Acoustic Levitators
(2020-01-01)
Acoustic levitation (Aclev) is an important tool to noncontact handling of containerless objects. In the recent years, many devices have been successfully developed due to the stable behavior of the Aclev devices. As a ...
Could cell membranes produce acoustic streaming? Making the case for synechococcus self-propulsion
(Pergamon-Elsevier Science Ltd, 2011-04)
Sir James Lighthill proposed in 1992 that acoustic streaming (AS) within the mammalian cochlea could play a role in the transmission of acoustic signals to the auditory sensory cells. Microelectromechanical devices for ...
Synthesis of porous-acoustic absorbing systems by an evolutionary optimization method
(Taylor & Francis LtdAbingdonInglaterra, 2010)
An approach for side scan sonar acoustic images segmentation using programmable logic
(Institute of Electrical and Electronics Engineers, 2015-05)
In applications related to maintenance of underwater infrastructure in harbour installations, cables and pipelines, it is necessary to separate the relevant objects of study from the rest of the acoustic image obtained by ...
Acoustic settings combination as a sensory crispness indicator of dry crispy food
(2020-04-01)
Crispness is a critical attribute of quality for crispy products, which can be evaluated through both instrumental and sensory analyses. The aim of the study was to identify the best combination of settings of a device ...
Diamond-Based Thin Film Bulk Acoustic Wave Resonator for Biomedical Applications
(IOP Publishing, 2013)
Nowadays it is in constant growing the development of thin film bulk acoustic resonators. If the piezoelectric material is going to be implanted in the human body, an important requirement is the biocompatibility of ...
Comparative Study on Feature Selection and Fusion Schemes for Emotion Recognition from Speech
The automatic analysis of speech to detect affective states may improve the way users interact with electronic devices. However, the analysis only at the acoustic level could be not enough to determine the emotion of a ...
