Solution of an industrially relevant coupled magneto–mechanical problem set on an axisymmetric domain
Eddy currents are generated when low frequency magnetic fields interact with conducting components and this, in turn, generates Lorentz forces, which can cause these metallic components to deform and vibrate. An important application of this magneto–mechanical coupling is in coil design for magnetic resonance imaging scanners, where such vibrations can have unwanted effects such as ghosting of images, reduction of the life span of devices and discomfort for the patient. This work is aimed at developing an accurate computational tool for better understanding these deformations by considering a benchmark problem proposed by Siemens plc (Kruip, personal communication, 2013) on an idealised axisymmetric geometry. We present a new fixed point algorithm and develop new weak variational statements, which use a stress tensor approach for force calculation and permit discretisation using H1 conforming hp-version finite elements. Numerical results are included, which show the importance of high order finite elements for predicting the eddy currents and the associated coupling in the resonance region

Dyslexia in The Digital Age : making IT work
Manual sobre el papel de la tecnología en la vida de las personas con dislexia, ya sea en la escuela primaria, en la universidad, en el trabajo o en cualquier otro lugar. La tecnología es parte del proceso para minimizar el impacto de la dislexia en los individuos y para ayudarlos en las dificultades que se enfrentan en situaciones cotidianas. Para ello, proporciona marcos de perspectivas teóricas y después la aplicación práctica, incluyendo revisiones de los tipos más comunes de software. Hay consejos prácticos sobre cómo apoyar a las personas con dislexia en el uso de la tecnología, incluida la forma de obtener el máximo provecho de lo que está disponible. Pone de relieve el estado de la tecnología punta, y sugiere lo que todavía queda por hacer para que esta tecnología sea realmente propicia para todos los disléxicos.SCBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín, 5 - 3 planta; 28014 Madrid; Tel. +34917748000; [email protected]
