Utvärdering av mätningar på en solvärmeanläggning för en industribyggnad. Solvärmeanläggningen används för förvärmning av tappvarmvatten och för värmning av ventilationsluft till en stor maskin- och lagerhall.

Popular Abstract in Swedish Ett centralt problem inom området datorseende är att utifrån bara ett antal bilder av föremål, återskapa formen av föremålet som avbildats. Samtidigt vill man även återskapa hur kameran rört sig mellan de olika bilderna tagits. Detta är det så kallade struktur och rörelse-problemet. I avhandlingen löses detta problem för olika typer av kameror samt olika typer av objektThis thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. Much of the thesis is centred on the problem of finding initial estimates of the structure and the motion using a small set of image data. These initial estimate

Surveillance of group A streptococcal (GAS) infections was undertaken as a major component of the European Commission-funded project on severe GAS disease in Europe (strep-EURO). One aim of strep-EURO was to improve the quality of GAS characterization by standardization of methods. An external quality assurance study (EQA) was therefore carried out to evaluate current global performance. Eleven st

This paper describes an instrument - the Housing Enabler - used in the assessment of housing accessibility. The tool was developed from the original Enabler idea by Steinfeld et al (1979), resulting in an instrument for reliable assessment of the accessibility of the housing environment and the immediate outdoor environment in terms of occupational therapy. Apart from a description of the instrume

We investigate the performance of overload control through queue length for two different web server architectures. Both of them use finite queue lengths to prevent servers from being overloaded. One architecture prioritizes requests from established sessions while the other treats all requests equally. First, we introduce queueing models for these two systems. Then, we define and explain a new we

The fine-structure splittings of highly excited F-states in Cs were measured using high-resolution laser spectroscopy. The 12 and 132F states were found to be inverted with splittings ?E (122F)=-522(3) MHz and ?E (132F)=-416(3) MHz.

Leucotrienes are synthesized from arachidonic acid. They are potent proinflammatory mediators that contribute to bronchial hyperreactivity. Antileukotrienes constitute a new group of antiasthmatic drugs. Zafirlucast, a leukotriene receptor antagonist, is now registered in Ireland and Finland for the treatment of mild to moderate asthma. We have studied the literature on antileukotrienes and have f

Primary hyperparathyroidism (pHPT) is associated with an increased fracture risk, and decreased bone density thus has been considered an indication for surgery. However, many pHPT patients have a multifactorial risk profile for osteoporosis and bone fractures. The aim of the present study was to evaluate variables associated with fracture risk within the group of pHPT patients. A series of 203 con

This study was designed to investigate the motives patients give for attempting suicide and the associations between these motives and diagnosis, various psychiatric features, suicidal intent and socio-demographic characteristics. The Motives for Parasuicide Questionnaire (MPQ), comprising 14 suggested motives, was presented to 53 patients at a psychiatric ward that specialized in suicide attempte

Polysulfones (PSUs) carrying short pendant alkyl side-chains with terminal sulfonic acid units have been prepared and studied as proton-conducting membrane materials. The first step in the preparation involved quenching of lithiated PSU with SO2 gas, resulting in sulfinated PSU. In the second step, the lithium sulfinate units on the polymer were reacted with sodium 2-bromoethanesulfonate, sodium 3

The max-bisection problem is to find a partition of the vertices of a graph into two equal size subsets that maximizes the number of edges with endpoints in both subsets. We obtain new improved approximation ratios for the max-bisection problem on the low degree k-regular graphs for 3 less than or equal to k less than or equal to 8, by deriving some improved transformations from a maximum cut into

The weighted oscillator strengths (gf) and the lifetimes presented in this work were carried out in a multiconfiguration Hartree-Fock relativistic approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with intensity observa
