Evaluation processes: Lessons from Bateson’s second order learning

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

Kristen mystik. Ur psykologisk synvinkel. Del II: Från Birgitta till Thomas Merton

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

Evaluation of a Parabolic Concentrating PVT System

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

Characterization of tensile fracture properties of paper

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

Single Antenna Anchor-Free UWB Positioning based on Multipath Propagation

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
