We show that twisting of an infinite straight three-dimensional tube with non-circular cross-section gives rise to a Hardy-type inequality for the associated Dirichlet Laplacian. As an application we prove certain stability of the spectrum of the Dirichlet Laplacian in locally and mildly bent tubes. Namely, it is known that any local bending, no matter how small, generates eigenvalues below the es
In her ”true” stories Buried Alive and Asylum Granted Liza Marklund, Swedish journalist and crime writer, acts as a ghost writer for Maria Eriksson’s presumed life story of abuse, hiding and flight to the USA where she, according to Marklund’s novel, was granted asylum. In 2008 the journalist Monica Antonsson published Mia – The Truth About Buried Alive. In the book she questions the factual backg

Computational methods within structural acoustics, vibration and fluid-structure interaction are powerful tools for investigating acoustic and structural-acoustic problems in many sectors of industry; in the building industry regarding room acoustics, in the car industry and aeronautical industry for optimizing structural components with regard to vibrations characteristics etc. It is on the verge
The impact of European Union law on the regional and local levels in the Member States has been underestimated for a long time now. Today, however, it is clear that the impact of European Union law on these levels is important, not least as a consequence of the deregulation that has been carried out in most Member States in recent years. As local markets open up for competition, the scope of EU la
A cylindrical bushing subjected to a stationary cyclic load is analysed with emphasis on the amplitude and frequency dependent damping and modulus. The material parameters were determined from a dynamic shear test, in terms of a viscoelastic-elastoplastic model. Using an overlay of finite element meshes, the material model was implemented in a finite element model of the cylindrical bushing and su
