Loudspeaker drivers are energy transducers: their main goal is to efficiently convert electrical energy to acoustic energy (sound), through the movement of mechanical parts. As such, they are prime candidates for the application of multiphysics methods and tools. The talk will outline ... Per saperne di più
Superconducting GHz electronics circuits are frequently used in Radio Astronomy instrumentation. The features of these instrumentations can be significantly improved by using tuneable capacitances, which can be realized by electrically actuated, micromechanical bridges (MEMS) made of ...

A good approximation of rough surfaces and their random behaviour is very important in some engineering problems. Fractal modelling provide an alternative to generate rough surfaces based in statistically self-similar non-Euclidean geometries, as seen in [Fig. 1]. Through a frequency ... Per saperne di più
Teledyne Marine developed a system for the long-range ocean acoustic tomography, which uses a tunable, high-efficiency sound resonator. The high-Q resonator tunes to match the frequency and phase of a reference frequency-modulated signal. The analysis of a high-Q resonant organ pipe with ... Per saperne di più
Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... Per saperne di più
The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... Per saperne di più
Surface and solution kinetics for redox systems can be reliably and accurately studied using hydrodynamic electrochemical methods, particularly a rotating disk electrode (RDE). The RDE consists of a disk electrode usually made of glassy carbon or noble metals imbedded in a rod of ... Per saperne di più
This paper reports the modelling and analysis of three dimensional negative dielectrophoretic traps for cell trapping applications. Dielectrophoresis is a well-established technique for cell analysis and cell trapping. Planar electrodes, at the bottom of a microfluidic channel, have been ... Per saperne di più
A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... Per saperne di più
Introduction: RFID system uses a Transponder and the near field communication (NFC) antenna and a matching circuit (Figure-1) in which at least latter two must be optimally designed for a higher efficiency. Typically, RFID antennas are flat inductive coils with 2 to 4 turns and are ... Per saperne di più
