Risk and Vulnerability Analysis of Interdependent Technical Infrastructures: Addressing Socio-Technical Systems

The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to

Historieämnets janusansikte

Ett antologikapitel som behandlar hur man definiererar, identifierar och kvalificerar kunskapsutveckling i historia utifrån frågorna varför det är bra att läsa historia och vad en historiker kan som inte andra kan.

Zero-temperature phase diagram for strongly correlated nanochains

Recently there has been a resurgence of intense experimental and theoretical interest on the Kondo physics of nanoscopic and mesoscopic systems due to the possibility of making experiments in extremely small samples. We have carried out exact diagonalization calculations to study the effect of the energy spacing Delta of the conduction band on the ground-state properties of a dense Anderson model

Experimental and theoretical results of a humidification tower in an evaporative gas turbine cycle pilot plant

The Evaporative Gas Turbine Pilot Plant has been in operation at Lund Institute of Technology in Sweden since 1997. In this cycle low-grade heat in the flue gases is utilized for water evaporation into the compressed air in the humidification tower. This result in, amongst others, power augmentation, efficiency increase and lower emissions. This article presents the experimental and theoretical re

MIMO PID Tuning via Iterated LMI Restriction

We formulate multi-input multi-output (MIMO) proportional-integral-derivative (PID) controller design as an optimization problem that involves nonconvex quadratic matrix inequalities. We propose a simple method that replaces the nonconvex matrix inequalities with a linear matrix inequality (LMI) restriction, and iterates to convergence. This method can be interpreted as a matrix extension of the c

Grundskollärares tankar om kompetensutveckling (Compulsory school teachers' thoughts about competence development)

Popular Abstract in Swedish Avhandlingen handlar om lärares tankar om kompetensutveckling med utgångspunkt i intervjuer med olika lärare vid tre tillfällen under 1990-talet. Lärare utvecklar i lärarutbildning allmänna lärarkunskaper, ämneskunskaper och ämnesdidaktiska kunskaper under 3,5 - 5,5 år, beroende på elevernas åldrar och lärarens ämneskombinationer. I yrkesverksamheten deltar lärare i ettThe development in society and school activities that have taken place during the past twenty years, form the background to the problem in this thesis. Liberal democratisation in the society as a whole and the global explosion of knowledge have made it necessary for teachers continuously to develop new knowledge. The over all aim of the thesis concerned the development of knowledge of variations
