Mating strategies and sexual conflicts in aquatic invertebrates: consequences for evolutionary differentiation

In this thesis I investigated how mating related strategies may differ among populations and how these strategies evolve in response to their local ecological environments. I have used two different study systems of aquatic invertebrates: diving beetles (Dytiscidae) and the fresh water isopod Asellus aquaticus. These systems have in common that they present distinct genetic variation within the sp

Web-based Information Systems - Infrastructures and Co-operational Patterns in a Networked Organisation

This paper contains a theoretically and empirically based analysis of infrastructures and co-operational patterns in a Scandinavian Internet consulting company. The purpose of the analysis originated from the hypothesis that Web-based Information Systems could especially facilitate work in distributed organisations, this as a platform for supporting collaboration, communication and co-ordination w

Non-Sequential Structure from Motion

Prior work on multi-view structure from motion is dominated by sequential approaches starting from a single two-view reconstruction, then adding new images one by one. In contrast, we propose a non-sequential methodology based on rotational consistency and robust estimation using convex optimization. The resulting system is more robust with respect to (i) unreliable two-view estimations caused by

High resolution core level photoemission of clean and adsorbate covered metal surfaces

A brief review is given of some fundamental aspects of high-resolution core-level photoemission and of its application to studies of pure and adsorbate covered metal surfaces. We first give a short description of the basic theory and then turn to a number of examples. The first group of examples is aimed at demonstrating the use of core-level binding energy shifts for deriving the surface and inte

Evaluation of the concentrating PVT systems MaReCo and Solar8

The European solar energy business faces the challenge of developing more cost-effective solar energy systems and one solution could be using concentrating hybrid PVT systems. Two such hybrids, the Swedish systems MaReCo and Solar8, are evaluated in this study. MaReCo is a fixed concentrating system with a high angle of acceptance. Solar8 is a new system, which is under development. It is inspired
