  1. 1. Combining analytical and iterative reconstruction in helical cone-beam CT

    Författare :Johan Sunnegårdh; Gösta Granlund; Per-Erik Danielsson; Michel Defrise; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cone-beam tomography; forward projection; image reconstruction; iterative reconstruction; ordered subsets; regularization; WFBP; Signal processing; Signalbehandling;

    Sammanfattning : Contemporary algorithms employed for reconstruction of 3D volumes from helical cone beam projections are so called non-exact algorithms. This means that the reconstructed volumes contain artifacts irrespective of the detector resolution and number of projection angles employed in the process. LÄS MER

  3. 2. Bottniska personnamn : frekvenser i skattelängder från mitten av 1500-talet

    Författare :Bengt Audén; Umeå universitet; []
    Nyckelord :tax register; naming-pratice; personal names; first names; patronymics; iterative name; Västerbotten; Österbotten;

    Sammanfattning : This thesis examines the naming-practice - particularly that of first-names - among men and women in the earliest tax registers of the 1540's from the northernmost Swedish provinces of Västerbotten and Österbotten. The aim of the thesis is first and foremost to describe, and to some extent explain, the naming-practice of the permanent population, with particular reference to the similarities and differences between the two provinces as far as personal names are concerned, and to their frequency and distribution.

  4. 3. Residue fixed point index and wildly ramified power series

    Författare :Jonas Nordqvist; Karl-Olof Lindahl; Robert Laurent Benedetto; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wildly ramified power series; residue fixed point index; formal invariant; iterative residue; ramification numbers; non-archimedean; discrete dynamical systems; arithmetic dynamics; periodic points; Nottingham group; Mathematics; Matematik;

    Sammanfattning : This thesis concerns discrete dynamical systems. These are systems where the dynamics is modeled by iterated functions. There are several applications of discrete dynamical system e.g. LÄS MER

  5. 4. Understanding the Designing of Knowledge Work Support Tools as a Situated Practice

    Författare :Niclas Eberhagen; Anita Mirijamdotter; Ina Wagner; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conceptual model; participatory design approach; design science; explorative and iterative design; knowledge transitions; Information technology; Informationsteknik; Informatik; Information Systems;

    Sammanfattning : The aim of the thesis is twofold. First, a need is exposed for adopting a situated design perspective in designing computer-based tools that support knowledge work. Second, an examination is made of what this perspective may reveal concerning the nature of processes and relations within the design situation. LÄS MER

  7. 5. Model Predictive Control in Flight Control Design : Stability and Reference Tracking

    Författare :Daniel Simon; Johan Löfberg; Sébastien Gros; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control;

    Sammanfattning : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. LÄS MER
