  1. 1. Interlaced proton grid therapy: development of an innovative radiation treatment technique

    Författare :Thomas Henry; Irena Gudowska; Tony Lomax; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; grid therapy; spatially fractionated therapy; interlacing; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Spatially fractionated radiotherapy, also known as grid therapy (GRID), has been used for more than a century to try to treat several kinds of lesions. Yet, the grid technique remains a relatively unknown and uncommon treatment modality nowadays. LÄS MER

  3. 2. On Uniformly Random Discrete Interlacing Systems

    Författare :Erik Duse; Kurt Johansson; Patrik Ferrari; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis concerns uniformly random discrete interlacing particle sys-tems and their connections to certain random lozenge tiling models. In par-ticular it contains the first derivation of a relatively unknown universal scalinglimit, which we call the Cusp-Airy process, of certain lozenge tiling modelsat a cusp point. LÄS MER

  4. 3. Ghostpeakons

    Författare :Budor Shuaib; Hans Lundmark; Krzysztof Marciniak; Erik Wahlén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we study peakons (peaked solitons), a class of solutions which occur in certain wave equations, such as the Camassa–Holm shallow water equation and its mathematical relatives, the Degasperis–Procesi, Novikov and Geng– Xue equations. These four non-linear partial differential equations are all integrable systems in the sense of having Lax pairs, infinitely many conservation laws, and multipeakon solutions given by explicitly known formulas.

  5. 4. 3D-Weaving and Noobing: Characterization of Interlaced and Non-interlaced 3D Fabric Forming Principles

    Författare :Nandan Khokar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : TEXTILE-based composite materials are the rapidly developing light-weight engineering materials. Fabrics constitute the reinforcement component of the composite material. The fabrics used in composites manufacture are referred to as preforms and are especially engineered as a single-fabric system to impart reliability and performance. LÄS MER

  7. 5. Qualitative and Spectral theory of some regular non-definite Sturm-Liouville problems

    Författare :Mervis Kikonko; Sten Kaijser; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : In this Licentiate thesis, we study some regular non-definite Sturm-Liouville problems. In this case, the weight function takes on both positive and negative signs on a given interval [a, b]. One feature of the non-definite Sturm-Liouville problem is the possible existence of non-real eigenvalues, unlike in the definite case (i.e. LÄS MER
