The material model consists of a viscoelastic Burgers element and an additional viscoplastic Bingham element when the effective stress exceeds the yield stress. For partly plastic vessel walls, expressions are derived for the stress and strain state in pressurised or relaxation loaded thick-walled cylinders in plane strain and spheres. For the spherical problem, the material compressibility is acc

This paper examines the role communication strategies play in the maintenance of communication in a classroom. The effect these strategies may have on the acquisition of a language is also discussed. There is often a lack of communication in a Swedish foreign language classroom which leads to the inability to communicate in a native-like way even after several years of learning the language. This

The NorduGrid project designed a Grid architecture with the primary goal to meet the requirements of production tasks of the LHC experiments. While it is meant to be a rather generic Grid system, it puts emphasis on batch processing suitable for problems encountered in High Energy Physics. The NorduGrid architecture implementation uses the Globus ToolkitTM as the foundation for various components,

We consider a networked control system where a linear time-invariant (LTI) plant, subject to a stochastic disturbance, is controlled over a communication channel with colored noise and a signal-to-noise ratio (SNR) constraint. The controller is based on output feedback and consists of an encoder that measures the plant output and transmits over the channel, and a decoder that receives the channel

The physical bounds for antennas above a ground plane is analyzed in this paper. Optimal antenna G/Q ratio and Q factor are calculated using convex optimization from stored electric and magnetic energy matrices, obtained from a method of moments solver. Physical bounds for a patch antenna with different heights above a ground plane are investigated. Results are verified using commercially availabl

Context: The Gaia project will determine positions, proper motions, and parallaxes for more than one billion stars in our Galaxy. It is known that Gaia's two telescopes are affected by a small but significant variation of the basic angle between them. Unless this variation is taken into account during data processing, e.g. using on-board metrology, it causes systematic errors in the astrometric pa

Varying degrees of collaboration and consultation in the area of child and family welfare in the public sector has grown rapidly since the 1980s, especially concerning children at risk. Collaboration is understood to provide a more holistic view of the individual's needs, lead to better care and treatment as well as increase knowledge in general. Collaboration in that sense constitute a flexible a
