The purpose of this study was testing and performance simulation of an innovative tracking hybrid solar system being developed by the Swedish Company Arontis. The Solar8 collector produces both electrical and thermal energy in one system. Its performance was compared with conventional photovoltaic panels and solar thermal collectors working side-by-side which are already on the market. The solar8

A relationship between stress and deformation can be evaluated from the load and elongation recorded in the tensile test of a strip of paper. This relationship characterizes the fracture properties of the paper. It shows how the stress acting across a fracture region decreases as the deformation increases.The relationship can be used in strength analysis by the finite element method and for the de

Radio based localization and tracking usually require multiple receivers/transmitters or a known floor plan. This paper presents a method for anchor free indoor positioning based on single antenna ultra wideband (UWB) measurements. By using time of arrival information from multipath propagation components stemming from scatterers with different, but unknown, positions we estimate the movement of t

The thesis describes the neural precursor cell line RN33B transplanted subretinally to adult healthy and young dystrophic rat retina. The cell line is generated from E12,5 rat raphe nucleus and transduced with the temperature sensitive mutant of the Simian Virus 40 (SV40) large T-antigen. The transplanted cells can be detected by the reporter genes for beta-galactosidase (beta-Gal) and the green f

Success of design projects depends on their quality from a technical and economic point of view and on the quality of their implementation and use. This paper discusses a computer aided planning (CAP) technique and its applicability and quality in both these respects. One version of the CAP-technique is developed for planning of industrial working environments and another version for planning of r

This paper presents a combined control and information model. Existing concepts from the information system area are modified to suit batch applications. The model has been applied to a simulated scenario consisting of a multi-purpose multi-path batch cell. The goal of the information model is to establish a framework for information systems that supports integrated batch plant operation.
