The paper deals with the structure-motion problem for images of point configurations taken by uncalibrated cameras. Using a parametrisation by affine shape and kinetic depth, a complete and explicit characterisation of the imaging geometry is given, including the shape of the object configuration and the positions of the cameras relative to the scene. No epipolar geometry is used. It is shown that

This paper provides new and interesting features on an extremal problem in the space of Hardy functions, $H^p, \; 0

Popular Abstract in Swedish En betydande del av kemin i naturen och inom industrin äger rum i en omgivning av andra molekyler. Reaktioner, övergångar, interaktioner och andra kemiska processer påverkas nästan alltid utav omgivningen. Dessa modifikationer eller omgivningseffekter beror i grund och botten på växelverkan mellan molekylerna, den så kallade intermolekylära växelverkan. Det speciella faA considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. These modifications or environment effects depend ultimately on the interactions between the molecules, the so called intermolecular interactions. The special case of effects induce

Wear of the UHMWPE component is one of the major concerns in joint replacement surgery, triggering prosthetic loosening leading to revision. The understanding of the mechanisms of material degradation, especially in regard to oxidation, is one of the keys to significantly improve the mechanical properties. This work focused on the relationship between the failure mechanism, crosslinking and oxidat

Popular Abstract in Swedish Bostadsanpassning är en vanlig åtgärd inom kommunal service och rehabilitering. Avsikten är att ta bort fysiska miljöhinder i bostaden och den nära utemiljön för underlätta vardagliga aktiviteter och möjliggöra ett självständigt liv. Enligt svensk plan- och bygglagstiftning skall alla bostäder som byggs eller genomgår omfattande renoveringar vara tillgängliga och användHousing adaptation is a common intervention, in Sweden granted by municipal authorities, and performed in order to remove environmental barriers and enhance daily activities. In spite of increasing costs, efficient strategies for evaluation of the intervention are lacking. In this thesis, occupational therapy clients living in a south Swedish municipality and receiving housing adaptation grants we

Quantum measurement theory has a peculiar nature with its TWO processes of assertibility, by proof and by measurement, which is beyond formal logic. This two-sortedness with respect to assertibility is discussed in terms of developments of many--sorted logics, sometimes referred to as Logica Magna. Although useful insights are obtained this way, we argue that there is a nonseparability of inferrib

The electrochemical, spectroelectrochemical, and kinetic investigations of two preparations of Cerrena unicolor laccase, lyophilized (LLAC) and nonlyophilized frozen enzymes (FLAC), were performed. It was found that the value of the redox potential of the T1 site of C. unicolor laccase is ca. 750 vs. NHE. It was also shown that one of the redox potentials of the T2/T3 cluster of C. unicolor laccas

Pheromone-binding proteins (PBPs) are soluble transporter proteins that increase the capture and the solubilization of pheromone molecules in the lymph surrounding the olfactory receptors. A polymerase chain reaction-based method was used to identify PBP genes in Agrotis species for an evolutionary genomic study of noctuid moth PBPs. From genomic DNA we determined the structure of different PBP ge

High-spin states of the isotopes In-103,In-105,In-107,In-109 have been investigated using in-beam gamma-ray spectroscopic methods. Results from three different experiments are presented. Targets of Fe-54, Cr-50, and Mo-92 were bombarded by a 270 and 261 MeV Ni-58 beam and by a 95 MeV F-19 beam, respectively. Reaction channel separation was achieved with a charged-particle detector array and in the

The sodium (Na+)/iodide (I-)-symporter (NIS) is abundantly expressed and accumulates iodide in thyroid follicular cells. The NIS is also found in extrathyroidal tissues, particularly gastric mucosa. Controversies exist on the localization of extrathyroidal NIS. We have studied the presence of both NIS peptide and NIS messenger RNA (mRNA) in the digestive tract and thyroid from different mammals. T

Wilms tumor (WT) is characterized by a nonrandom pattern of chromosome aberrations, but the clinical significance of different cytogenetic patterns is unknown. The present study describes the cytogenetic findings and the clinical course in a cohort of 39 children with WT. Samples for short-term culturing and cytogenetic analysis were obtained during a 15-year period. Clonal chromosome aberrations

Isometric force, glycogen phosphorylase activity and lactate production were measured under conditions known to alter intracellular Ca2+ and cAMP to assess the role of these messengers in the coordination of metabolism with contractility in rat portal vein. Total phosphorylase (a + b) activity, was independent of treatment. The activity ratio phosphorylase activity ratio in the presence of isoprot

A new trend in recent years is to reduce the solid oxide fuel cell (SOFC) operating temperature to an intermediate range by employing either a thin electrolyte, or new materials for the electrolyte and electrodes. In this paper, a numerical investigation is presented with focus on modeling and analysis of transport processes in planar intermediate temperature (IT, between 600 and 800 degrees C) SO

The effects of restrained cervical mobility on pursuit eye movements (PEMS), voluntary saccades and postural control, as measured by posturography, were studied in 11 healthy subjects whose cervical spine movement had been restrained for 5 days by means of a rigid neck-collar. At day 5 mean peak velocity of voluntary saccades at amplitudes of 40 degrees and 60 degrees was significantly reduced, as

Cystatin F is a recently discovered type II cystatin expressed almost exclusively in immune cells. It is present intracellularly in lysosome-like vesicles, which suggests a potential role in regulating papain-like cathepsins involved in antigen presentation. Therefore, interactions of cystatin F with several of its potential targets, cathepsins F, K, V, S, H, X and C, were studied in vitro. Cystat

The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. In order to highlight the physical mechanism of flow separation, only one wall of the channel is fitted with periodic ribs. The inter-rib spacing is set such that the reattachment is allowe
