Hälso- och sjukvården står inför en mängd förändringar och en allt mer komplex och utmanande situation, världen över. Förändringarna sker tvärsektoriellt och på alla plan: Ökad kundfokusering, nya rön om styrning och ledning, forskningsframsteg, ny teknik, ny vårdpraxis, öppna kvalitetsjämförelser, kompetensspecialisering och maktförskjutningar. Förändringarna sker inte bara lokalt utan även regio
We provide a general mechanism for obtaining uniform information from pointwise data even when the pertinent quantities are highly discontinuous. Some of the applications are almost too good to be believed: If a diffeomorphism of a com-pact Riemannian manifold has nonzero Lyapunov exponents everywhere then the nonwandering set is uniformly hyperbolic. If, in addition, there are expanding and contr
Parallel robots are generally said to be more accurate but to have a smaller workspace compared to serial robots. With the Gantry-Tau robot, a parallel robot with a large, reconfigurable workspace was presented. This article tries to identify the maximum achievable end-effector positioning accuracy of the Gantry-Tau robot. To this end, a couple of new kinematic error models are presented and evalu
A number of minimal problems of structure from motion for cameras with radial distortion have recently been studied and solved in some cases. These problems are known to be numerically very challenging and in several cases there exist no known practical algorithm yielding solutions in floating point arithmetic. We make some crucial observations concerning the floating point implementation of Gröbn
This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. The second part, consisting of the final chapter, focuses on the analysis of panel data and proposes a new test for poolability of the slope coefficients in cointegrated panel regressions. Chapter
Malignant glioma and glioblastoma multiforme form the largest group of highly malignant brain tumours, for which there is yet no definitive cure. Different approaches to treatment have been tried, in vain or with minimal benefit for the patient. In addition to surgery, radiation and chemotherapy, immunotherapy aiming at evoking an inflammatory reaction against the tumour itself has been tried. Imm
