Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion ... Per saperne di più
The high luminosity large hadron collider (HL-LHC) project aims at increasing the integrated luminosity by a factor of 10 from its original value (from 300 to 3000 fb-1) leading to the potential extension of scientific discoveries. To attain this goal, important upgrades will take place ... Per saperne di più
Most conventional wastewater treatment processes are quite energy-intensive. Global wastewater production is increasing due to growth in population, industrialization, and urbanization, creating an urgent need for energy-efficient wastewater treatment technologies. Moreover, waste ... Per saperne di più
In this paper, a methodology to simulate the electric behavior of spiral inductances is presented and discussed. All the methodology is built with the COMSOL software used with the Matlab scripting interface and then allows performing fully parameterized simulations. The program ... Per saperne di più
Two finite element models have been developed to investigate the acoustic radiation from a Pratt truss train bridge. The first model was a time dependent structural model that determined the vibration response of the structure due to two wheels, representing a single axle, moving across ... Per saperne di più
The vibration of an electrodynamic loudspeaker driver causes a resulting sound pressure. For simple pistonic vibration, there is a simple relationship between the vibration and the sound pressure. For complex vibration patterns, however, different parts of the vibrating surface ... Per saperne di più
A installation caused severe hum, with 30 Hz as dominant frequency, causing serious annoyance. The acoustic study showed resonances around 30 Hz. Poor flow conditions existed at the inlet and outlet of the forced draft fan. Flow patterns were studied using CFD. Both the inlet and ... Per saperne di più
A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... Per saperne di più
When acoustic applications include small geometries, i.e. mm/submillimeter range, so-called thermoviscous effects can greatly affect the pressure response. This paper deals with acoustic topology optimization of such miniature structures with thermoviscous effects taken into account. ... Per saperne di più
When placing a loudspeaker in a cabinet, standing waves inside the cabinet affect the frequency response with ripples. This peaks and dips due to pressure cancellation inside the cabinet have an effect on the diaphragm and generating sound out from the vents. If it was in a condition of ... Per saperne di più
