This paper examines the potential benefits of applying next best view planning to sequential 3D reconstruction from unordered image sequences. A standard sequential structure-and-motion pipeline is extended with active selection of the order in which cameras are resectioned. To this end, approximate covariance propagation is implemented throughout the system, providing running estimates of the unc
A cost-efficient way to increase power in a genetic association study is to pool controls from different sources. The genotyping effort can then be directed to large case series. The Nordic Control database, NordicDB, has been set up as a unique resource in the Nordic area and the data are available for authorized users through the web portal (http://www.nordicdb.org). The current version of Nordi
Gaucher disease (GD) patients cannot metabolize glycosphingolipids properly due to deficiency of the enzyme glucosylceramidase (GCase). The lack of animal model for GD has hindered comprehensive investigation of disease mechanisms and also the development of curative treatment strategies such as hematopoietic stem cell (HSC) targeted gene therapy. Previous GCase deficient mice have either been let
Popular Abstract in Swedish Standard-12-avlednings-EKG är fortfarande ett av de viktigaste och vanligaste redskapen för att diagnostisera hjärtsjukdom trots att ett flertal olika undersökningstekniker har utvecklats under åren. Vid standard-EKG används 10 elektroder, 6 på bröstkorgen och 4 distalt på armar och ben. Inom både industrin och akademin har många års arbete lagts ned på utveckling av deThe standard 12-lead electrocardiogram (ECG) remains one of the most important and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both industry and academia hav
Graphic correlation using graptolites and conodonts provides a high-resolution timescale for correlating from coastal to deep oceanic sections and, thereby, also a detailed record of the sequence of changes during the Mulde Secundo-Secundo Event. That interval includes sedimentary facies otherwise unknown in older Wenlock to early Ludlow strata on Gotland. The identified sequence of changes includ
Synthesis of mediators of fever, pain and inflammation as well as protection against reactive molecules and oxidative stress is a hallmark of the MAPEG superfamily (membrane associated proteins in eicosanoid and glutathione metabolism). The structure of a MAPEG member, rat mictosomal glutathione transferase 1, at 3.2 angstrom resolution, solved here in complex with glutathione by electron crystall
This thesis concerns the numerical approximation of the solutions to hyperbolic conservation laws. In particular the research work focuses on reconstruction techniques; the reconstruction being the key ingredient in modern finite volume schemes aiming to increase spatial order of accuracy. To better conform to the nature of the solutions to the hyperbolic problems, the reconstructing fu
The MAX-IV storage rings are being studied at MAX-Lab. In this paper, we present the magnetic measurements of the soft bending magnet prototype. The magnet is introduced in the matching section of the 3 GeV storage ring lattice [Tarawneh, Proceedings of European Particle Accelerator Conference, July 2004, Lucerne, Switzerland] mainly to reduce the power of the synchrotron radiation hitting the ups
Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. The theme of this thesis is to use invariants to solve these
1. Growth and reproduction of Daphnia fed lake seston were measured in two categories of meso- to eutrophic lakes differing with respect to terrestrial organic matter influence (humic and clear water lakes). The content of highly unsaturated fatty acids (HUFA), P and N, as well as the taxonomical composition of seston were analysed.2. Seston HUFA and C : P ratios were similar between lake categori
Pure Sb0.9V0.9O4 and various preparations with excess of either vanadia or antimony oxide, including mechanical mixtures, have been investigated for propane ammoxidation to acrylonitrile. The catalysts were characterized before and after use in catalysis by various methods, including electron microscopy, infrared spectroscopy and XPS. The catalytic data show that preparations with approximate to S
The screen-printed four-electrode system was used as the amperometric transducer for determination of phenols and pesticides using immobilised tyrosinase. peroxidase. acetylcholinesterase and butyrylcholinesterase. Acetylthiocholine chloride was chosen as substrate for cholinesterases to measure inhibition by pesticides, hydrogen peroxide served as co-substrate for peroxidase to measure phenols. T
During recent years the nuclear decay modes of discrete prompt proton and a-particle emission from (super)deformed high-spin states have been discovered in nuclei in the Vicinity of Ni-56. The latest news from experiments performed at EUROBALL and GAMMASPHERE regarding these decays are presented and discussed.
Popular Abstract in Swedish Spektroskopi är den vetenskapsgren som används för att studera samspelet mellan strålning/ljus och materia för tillämpningar i både diagnostiska och terapeutiska syften. Då ljus sänds in i ett prov sätts olika fysikaliska processer igång. I denna avhandling studeras företrädesvis en process som kallas för absorption. Vid absorptionsspektroskopi är våglängden av ljuset, Tunable diode laser absorption spectroscopy can be utilised for gas detection in biological and medical applications. The common approach is to analyse transmitted light according to the Beer-Lambertian law. Normally, the light has a well-defined path length through the gas sample since it can be assumed that it has negligible scattering properties. Samples which, by contrast, have strong scatteri
We analyze the higher-twist effects and the SU(3)-flavor symmetry breaking in the correlation functions used to calculate form factors of pseudoscalar mesons in the QCD light-cone sum rule approach. It is shown that the Ward identities for these correlation functions yield relations between twist-4 two-and three-particle distribution amplitudes. In addition to the relations already obtained from t
To validate a modified ligand-binding assay for the detection of aggrecanase generated aggrecan fragments with the ARGS neoepitope in synovial fluid (SF) and blood, and to verify the identity of aggrecan fragments found in blood.
Introduction: Identification of suitable candidates for cardioversion currently is not based on individual electrical and mechanical atrial remodeling. Therefore, this study analyzed the meaning of atrial fibrillatory rate obtained from the surface ECG (as a measure of electrical remodeling) and left atrial size (as measure of mechanical remodeling) for prediction of early atrial fibrillation (AF)
High-speed communication using the copper network, originally installed for telephony, is one of the dominant Internet access techniques. Several variants of a technology referred to as digital subscriber line (DSL) have been developed, standardized and installed during the last two decades. Essentially, DSL achieves high rates by exploiting wide bands of the copper cable channel. The shorter the
