An indoor positioning system (IPS) is a system to locate objects in indoor environments using radio waves, magnetic fields, acoustic, optical and video signals or other sensory information with help of a number of known reference positions. Nowadays, indoor positioning based services are used in a wide variety of areas and indoor positioning is getting considerable attention from both research and

Autoantibody-mediated diseases comprise a heterogeneous group of disorders in which the pathogenic potential of autoantibodies has been clearly demonstrated. In general, their treatment relies on the long-term use of systemic corticosteroids and other immunosuppressants that are associated with considerable adverse reactions. EndoS, an endoglycosidase derived from Streptococcus pyogenes, specifica

Today´s society depend on electric energy, in nuclear power plants this can be produced. Each nuclear reactor is situated inside a concrete containment reinforced with a post-tensioning system. The aim of this report is to analyse the state of the post-tensioning systems at Ringhals nuclear power plant. The purpose of a containment is to protect the outside world if an accident should occur. Tight

Over the past decade, organic–inorganic hybrid perovskites have revolutionized next-generation semiconductors, driving unprecedented advancements in cost-effective optoelectronics. While lead-based perovskite semiconductors exhibit exceptional optoelectronic properties, their inherent toxicity and vulnerability to environmental degradation remain significant barriers to widespread commerciali

LUPE is a modular software for calculation of brain perfusion parametric maps from dynamic susceptibility contrast perfusion weighted MR images.   Source code and a runtime version (.sav file) are published here under the terms of the GPL.

A series of triclinic Fe1−xAlxVO4 phases with 0 <= x <= 1 were prepared and used in the oxidation of methanol to formaldehyde. The activity measurements revealed that both the activity and especially the selectivity to formaldehyde increased with time of operation for at least 16 h, indicating restructuring of the catalysts. Characterisation of the catalysts with XRD, XANES, and electron microscop

This thesis concerns risk measures in theory and an empirical study of their accuracy in predicting future risks, back-testing them using an out-of-sample study with a rolling window scheme. The theoretical part includes a general presentation of risk, covers various risk measures – dispersion measures and safety measures – and attempts to sort out their advantages and disadvantages. The coherent
