From a construction point of view, neighborhoods with residents living at or below the poverty threshold are characterized by low energy efficiency buildings, in which people live in acoustic discomfort with no viable ...
Numerical simulation of cavitation erosion aggressiveness induced by unsteady cloud cavitation
(Multidisciplinary Digital Publishing Institute, 2020-08-01)
Article.
Accés obert
Article.
Accés obert
A numerical investigation of the erosion aggressiveness of leading edge unsteady cloud cavitation based on the energy balance approach has been carried out to ascertain the main damaging mechanisms and the influence of the ...
On the quantification of local power densities in a new vibration bioreactor
(Public Library of Science (PLOS), 2021-01-01)
Article.
Accés obert
Article.
Accés obert
We investigate the power densities which are obtainable locally in a vibration bioreactor. These reactor systems are of great relevance for research about oncological or antibacterial therapies. Our focus lies on the local ...

Article.
Accés obert
Article.
Accés obert
This paper investigates the possibility to realize solutions for buildings thermal and acoustic refurbishment by using end-of-life household materials, such as cardboard, clothes, and egg-boxes. These solutions can be ...
Ultrasonic vibration-assisted ball burnishing tool for a lathe characterized by acoustic emission and vibratory measurements
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
Article.
Accés obert
Article.
Accés obert
This paper focuses on a resonant system used to induce a low-amplitude movement and ultrasonic frequency to complement a ball burnishing process on a lathe. The system was characterized through the combination of different ...
Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe

Article.
Accés obert
Article.
Accés obert
In this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ...
Characterization of the effects of ingested bodies on the rotor–stator interaction of hydraulic turbines
(2021-10-14)
Article.
Accés obert
Article.
Accés obert
Runner and distributor blockages in hydraulic turbines occur due to the ingestion of external bodies such as rocks or logs. These obstructions can change the amplitude and uniformity of the pressure pulsations in the ...
