Introduction - The ability to achieve rapid and homogeneous mixing at microscales is one of the essential requirements for various lab-on-a-chip applications [1]. The flow at microscales is characterized by low Reynolds number, resulting in laminar flow patterns. Thus, the mixing at ... Mehr lesen
Ultrasound imaging probes are widely used for several types of diagnosis applications. In the present work we focus our attention on a disk-type probe, which is widely used in CW and PW operating conditions. In particular we present a 2D-axial symmetry FEM for the probe, capable to ... Mehr lesen
This paper presents a FEA approach to estimate temperature rise and thermal stress experienced in PZT/Solid structure due to internal heat generation and dynamic excitation. The power dissipative density consumed by structural damping of the mass structure, internal heat generation due ... Mehr lesen
Ultrasonic sensors are commonly used for a wide variety of non-contact presence, proximity or distance measuring applications in industry, especially the automotive branch. This paper shows how the radiation properties of bending-type ultrasonic transducers with rotational symmetry ... Mehr lesen
Pulse-echo FEM simulation is seldom found in literature for ultrasound imaging array probes, since the complete modeling of such device is extremely complicated. Nevertheless, the 2D FEM described in the present work was successful, thanks to the following design procedure (see figure): ... Mehr lesen
Charge transport behavior must be considered in developing HVDC design. In microscopic level, the space charge and conduction mechanisms are related with energy band‐gap and shallow/deep trap distribution and these come from chemical defects, physical disorder and impurities or by ... Mehr lesen
In the field of assessment methodologies, particular importance is given to Non-Destructive Testing Techniques, which aspire to achieve the highest number of information about materials and structures without altering their condition. Ultrasonic Testing exploits the transmission and ... Mehr lesen
A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. ... Mehr lesen
COMSOL Multiphysics was used to design a binocular load cell. A three-dimensional linear solid model of the load cell spring element was studied to quantify the high-strain regions under loading conditions. The load cell was fabricated from 6061 aluminum, and general purpose Constantin ... Mehr lesen
Marco Cati graduated cum laude and encomium citation in electronic engineering in 2001 from the University of Florence, where in 2005 he also received a Ph. D. degree in electronic engineering. In 2005 he joined the Research & Development Department of Esaote where he is currently in ... Mehr lesen
