Gas concentration and temperature excited Delft turbulent jet in acoustically flames
(Elsevier B.V., 2014)
A state-space modeling approach for active structural acoustic control
(IOS PRESS, 2009)
The demands for improvement in sound quality and reduction of noise generated by vehicles are constantly increasing, as well as the penalties for space and weight of the control solutions. A promising approach to cope with ...
Study of Knock Sensors as Low-Cost Alternatives to Acoustic Emission Sensors
(2020-06-01)
The real-time monitoring of manufacturing processes is essential to achieve high-quality standards and uniformity at reduced costs. The monitoring of machining processes is usually performed by acoustic emission sensors, ...
Ultrafast generation of optical and acoustic phonons in nanocrystallites
(Society of Photo-Optical Instrumentation Engineers, 2005-12)
We report on the impulsive generation of optical and acoustic phonons in CdTe0.68Se0.32 nanocrystallites embedded in glass, at room temperature. Using ultrafast laser pulses in a pump-probe configuration, we were able to ...
Experimental aspects of partially premixed pulsating combustion
(2005-12-27)
The pulsating combustion process has won interest in current research due to indications that its application in energy generation can offer several advantages, such as: fuel economy, reduced pollutants formation, increased ...
NOISE GENERATED BY CAVITATION IN ORIFICE-PLATES WITH SOME GASEOUS EFFECTS.
(1986-12-01)
An experimental investigation of the noise generated by cavitation in turbulent shear flows produced by confined sharp-edge orifice-plates is reported. The acoustic source strength of cavitation was determined by means of ...
Trees, shrubs and lawn: Acoustic effects in urban parks
(Universidad del Zulia, 2020)
Caracterização acústica através do levantamento de respostas impulsivas utilizando os métodos maximum-length sequence e time-stretched pulse
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia EletrônicaUTFPR, 2015-11-26)
The characterization of environments by measuring impulsive responses is required for venues that need special attention on the acoustic, such as theaters, mo-vie theaters and public houses. The characterization allows to ...
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 ...
