Popular Abstract in Swedish Urinavledning utförs när den normala urinblåsan ej fungerar normalt eller måste avlägsnas p.g.a. cancer. Vid operation enl. Bricker sys urinledarna till ett isolerat tarmsegment ( konduktor ), vars ena ände mynnar på huden som en stomi. Över öppningen på huden har patienten sedan ett uppsamlingsförband för urinen, en ' påse på magen'. Kontinenta former av urinvägsrekonsIn a long-term prospective follow-up in patients randomized to an ileal or colonic conduit, with implantation of one ureter using antireflux technique and the other without, the fall in the mean total GFR exceeded the expected age-related decline. The fall in the mean separate GFR did not differ between refluxing and antirefluxing anastomosis. Patients with a continent caecal reservoir (antireflux

Product innovation in highly complex and technological areas, such as medical technology, puts high requirements on innovation capability of an organization. Previous research and publications have highlighted organizational issues and learning matters as important and necessary for the development of innovation capability. Action learning require reflections of the ways things are carried out, ch

The direct and inverse scattering problems for a plane-stratified viscoelastic medium excited by a transient plane wave of SH or P-SV type are treated. The viscoelastic medium is characterized by two time and space dependent memory functions and a spatially dependent density. The direct and inverse problems are solved by a time-domain wave propagator method that is related to the Green functions t

Lund University, Sweden, is developing a video analysis system for making long-term behavioural studies, primarily in complex urban environments. Road users are detected using the KLT (Kanade-Lucas-Tomasi) interest point tracker. Trajectories are estimated using foreground–background segmentation, whereas speed is estimated using the shape analysis of interest points. The extracted trajectories ar

In his licentiate thesis, Calle Sjöström sums up his own and Certec's experience from almost five years' work on haptic interfaces for people with disabilities. The haptic technology tested have great potential for future development, but need refinement

High-level modeling languages are receiving increased industrial and academic interest within several domains, such as chemical engineering, thermo-fluid systems and automotive systems. One such modeling language is Modelica. Modelica is an open language, specifically targeted at multi-domain modeling and model re-use. Key features of Modelica include object oriented modeling, declarative equation

An analytical stiffness and eigenfrequency model of symmetric parallel 6-6 Stewart platforms (hexapods) is developed based on geometrical design variables to optimize the dynamical performance. The model is based upon Lagrangean dynamics in which the Bryant angles are used for the kinematics formulation. With the analytical eigenfrequency model, optimum stiffness characteristics can be obtained fo
