Metal foams are interesting materials with many potential uses. They are characterized by a cellular structure represented by a metal (or a metal alloy) and gas voids inside. A common metallic cellular material is a solid sponge, also known as open cell metal foam. Due to their intrinsic ... En savoir plus

The construction of a superconducting aircraft motor demonstrator is underway under ASuMED project. Magnetized stacks of commercial superconducting tapes will be applied in a rotor in place permanent magnets. The rotor will be cooled with liquid hydrogen down to approximately 20K to ...

Water transport in the public sewer system is often based on open channel flow, e.g. in a DN100 drainage pipe. Especially for low flow rates of less than 10 mL/s and with water levels of less than 4 mm, flow sensors are hardly available. In order to enable the measuring of very low ... En savoir plus

IntroductionA new circular polarized antenna model for mobile transmission has been implemented in COMSOL Multiphysics® for needs related to shooting sports events on the move. The antenna was required to work in the UHF television frequency band (specifically, 600 MHz) and, if ... En savoir plus

The significance of electrification of industry increases with the growing influence of renewable electricity as a primary energy source on earth. In this sense, microwave heating is a well-established electricity-based and market-mature technology employed on the commercial scale in ... En savoir plus

The next step in the evolution of the metal sector of Additive Manufacturing and especially for Laser based Powder Bed Fusion is the production of multi-material components as shown by [1]. Therefore, the powder application module must be able to selectively arrange different powders in ... En savoir plus

Optical wave interference can perform instantaneous operations, such as: addition, subtraction, multiplication, and more complex operations like Fourier transform [1]. Being able to develop an optical computer that directly executes these operations without the need for a digital ... En savoir plus

We consider the problem of calculating forces on high current solid conductors, as is present e.g. in substations[1]. This is of importance for the design of the station, in particular for the conductor geometry and mechanical support. The full calculation includes a treatment of the ... En savoir plus

For hydrogeologists pumping tests are the most common method to obtain characteristic aquifer properties, like transmissivity and storativity. For the evaluation of pumping tests it is common practice to compare field measurements and 1D analytical solutions. Numerical methods offer the ... En savoir plus
