There is today a lack of clinical techniques for detecting acute hypotension during conventional hemodialysis treat -ment, despite the fact that hypotension remains the - mosr common acute complication during hemodialysis. Hypotension is often followed by nausea, vomiting, and even fainting, not only strenuous for the patient but requires considerable attention from the nursing staf. The problem o

We consider the problem of stochastic control under power constraints. Problems such as linear quadratic optimal control with information constraints are instances of the problem considered. The calculations of the optimal control law can be done off-line as in the classical linear quadratic Gaussian control theory using dynamic programming, which turns out to be a special case of the new theory d

In the paper we address traffic engineering problems related to optimization of routing in IP networks applying destination-based shortest path routing (SPR) of the OSPF type. An SPR routing pattern is determined by a system of (administrative) weights defined over the set of IP links: the routes for IP forwarding are determined as the shortest paths computed locally at the nodes using the current

Popular Abstract in Swedish Denna avhandling presenterar resultat från experimentella studier av tensiders och enzymers beteenden vid modellytor. Ellipsometri var den i huvudsak använda tekniken i dessa undersökningar. Studier av tensidadsorption i statiska och dynamiska vätningssituationer initierades för att undersöka adsorptionsbeteenden i närheten av trefaslinjen under dynamisk vätning. I falThis thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. Studies of surfactant adsorption in static and dynamic wetting situations were performed to investigate adsorption behaviour close to the three-phase contact line (tpl) during dynamic wetting. It was demonst

We investigate whether the recently observed population of high-velocity white dwarfs can be derived from a population of binaries residing initially within the thin disc of the Galaxy. In particular, we consider binaries where the primary is sufficiently massive to explode as a Type II supernova. A large fraction of such binaries are broken up when the primary then explodes as a supernova, owing
