The main purpose of this thesis is to show in a case study how it is possible to inform, with Activity Theory, the design and evaluation of a pedestrian navigation system that uses audio-tactile feedback. The case study consists of an iterative design process that results in a tourist guide application used in a mobile phone. The interaction with the user is mostly through the audio and haptic mod
Abstract Digital visualization has gone through a revolutionary decade. Compared to other fields where these methods have been applied, archaeology has been, and still is, more resistant to integrating tools and instruments able to describe materials and scenarios with high resolution. This is partly due to the archaeological misconception of high cost of scientific equipment and the complexity in
Reversible protein phosphorylation by protein kinases and phosphatases is a common event in various cellular processes. The eukaryotic protein kinase superfamily, which is one of the largest superfamilies of eukaryotic proteins, plays several roles in cell signaling and diseases. We identified 482 eukaryotic protein kinases and 39 atypical protein kinases in the bovine genome, by searching publicl
The choice of procedure during public procurement is assumed to affect the overall result of the project. When studying the construction industry; delivery methods, payment systems and project specific variables may affect the end result. The question here is if project success is predicted by choice of procurement procedures. A survey was done on 222 road and railroad construction projects in Swe
We propose a method for identifying and ranking critical components and sets of components in technical infrastructures. Criticality is defined as the vulnerability of the system to failure in a specific component, or set of components. The identification of critical components is increasingly difficult when considering multiple simultaneous failures, especially component failures with synergistic
