This paper focuses on learning and reflection in evaluation processes. The needs and focus of evaluation change over the life of an Information System (IS) project. Evaluation does not necessarily always equal analysis, however, a meaningful evaluation can only be done if combined with analysis of the context. Evaluation processes must include some learning element to be contextually relevant. To

This is the fourth and final volume in a series of studies in the psychology of religious mysticism. As in his earlier volumes, the author focuses on central themes, such as the concept of God, the view of man, different spiritual exercises as prayer and meditation, types of mystical experience, and mors mystica, the notion that the self has to die and to be reborn. Slightly more than thirty impor
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
