  2. 16. Transport theory and finite element methods for mesoscopic superconducting devices

    Author : Kevin Marc Seja; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; non-equilibrium superconductivity; finite element methods; unconventional superconductors; quasiclassical theory; transport theory;

    Abstract : At low temperatures, electrons in a superconductor exhibit pairing correlations that result in a macroscopic, phase-coherent ground state. This leads to peculiar electromagnetic properties such as the flow of dissipationless charge currents and expelling of external magnetic fields. READ MORE

  4. 17. Cut finite element methods for interface problems

    Author : Thomas Frachon; Sara Zahedi; Anders Logg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : Interface problems modeled by Partial Differential Equations (PDEs) appear in a wide range of fields such as biology, fluid dynamics, micro and nano-technologies. In computer simulations of such problems a fundamental task is to numerically solve PDEs in/on domains defined by deformable interfaces/geometries. READ MORE

  6. 19. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals

    Author : Claudio F. Nigro; Christina Bjerkén; Ylva Mellbin; Pär A T Olsson; Reinhart Pippan; Malmö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-field theory; finite element method; corrosion; finite volume method; phase transformation; hydride; hydrogen embrittlement; linear elastic fracture mechanics;

    Abstract : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. READ MORE

  7. 20. Transient acoustic fields studied by pulsed TV holography

    Author : Staffan Schedin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Abstract : Many of the acoustic events that reach our ears are produced by impacted and vibrating bodies. Pulsed holographic interferometry is a suitable technique to record transient events, like sound waves in air from an impacted body or the wave propagation in solid objects. READ MORE
