I this thesis, optical studies of InAs quantum dots (QDs) in GaAs and InP are presented. The electronic structure of these zero dimensional structures, grown in the Stranski-Krastanow growth mode, was studied by photoluminescence spectroscopy (PL), junction space-charge techniques (JSCT) and photoconductivity (PC) measurements. For the InAs/GaAs system we present single-dot photoluminescence spec
Between 1996 and 2002, 16 patients with rheumatoid arthritis and failed total ankle prosthesis underwent tibiotalocalcaneal fusion using retrograde intramedullary nails. The functional outcome was evaluated using the AOFAS scoring system and the patients were also asked about their satisfaction. Radiographs were obtained for all 16 cases minimum 1 year after surgery. Thirteen of the 16 ankles wer

The purpose of this paper is to show how eye-tracking methodology can be used to study ‘inner space’; both from a theoretical point of view – the existence (or not) of internal image representations – as well as from an applied point of view – the usage of mental imagery in thinking and reasoning. First, we introduce the reader to the mental imagery debate. Second, we summarize studies on mental i
A high-bandwith robot-workpiece interaction requires a stiff robot without resonances in the frequency range of operation. In this article, the compliance dynamics of the Gantry-Tau parallel kinematic robot were identified using subspace-based identification and physical modeling. Measurements were performed both with a camera vision system developed and with a laser tracker. Although promising si
Atmospheric aerosol particles have substantial influence on climate and air quality. However, the anthropogenic influence on the atmospheric aerosol is still poorly known. This limits the understanding of past and future climate changes. Additionally, both epidemiological and toxicological studies indicate adverse health effects of inhaled aerosol particles. In order to study the effect of atmosph
Ibis paper deals with various methods of improved cooling of primary water in district heating (DH) substations and evaluates the benefit of an improved cooling from the perspective of the construction of an appropriate customer accounting method. The general benefit of an improved cooling is well-known: Less thermal stresses in pipelines, lowered heat and pumping losses and increased capacity in
Om synen på Gustav Vasa från 1500-talet till det sena 1900-talet.
This book provides (a) the first comprehensive description of the phonology and phonetics of Standard Mongolian, known as the Halh (Khalkha) dialect and spoken in Ulaanbaatar, the capital of the Republic of Mongolia; and (b) the first account in any language of the historical phonology of the Mongolian group of languages. The synchronic phonology is based on data collected by the authors and on th
Tidigare forskning om samverkan visar att samarbete innefattar problem och konflikter. Syftet med denna studie är att istället beskriva mer framgångsrik samverkan även om denna utspelas under kortare interaktionsfrekvenser. I boken diskuteras forskning som analyserat framgångsfaktorer men framförallt analyseras ett eget empiriskt material med fokus på hur och när aktörerna inom ungdomsvården framsPrevious collaboration research shows that problems and conflicts sometimes arise as a part of collaboration. This book analyzes successful cooperation unfolding during shorter interaction sequences. In this study I endeavour to describe the contributing factors that are necessary to achieve the phenomenon of a successful collaboration. I do this partially with help from studies published in previ
The dynamics of planetesimals and planetary cores may be strongly influenced by density perturbations driven by magneto-rotational turbulence in their natal protoplanetary gas disks. Using the local shearing box approximation, we perform numerical simulations of planetesimals moving as massless particles in a turbulent, magnetized, unstratified gas disk. Our fiducial disk model shows turbulent acc
Bipolaris sorokiniana is a fungal pathogen causing severe disease mainly in wheat and barley worldwide. In this thesis two aspects of the infection process were investigated: the adhesion mechanism of the fungus and the role of the non-host specific phytotoxin prehelminthosporol (PHL) in the disease. Adhesion of B. sorokiniana to artificial solid surfaces occurred in two stages: the first by conid
