  1. 6. A tale of trees and leaves : subtrees and local convergence

    Författare :Wang Ruoyu; Stephan Wagner; Haslegrave John; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tree; subtree; mean subtree order; Benjamini Schramm convergence; local convergence; Mathematics; Matematik;

    Sammanfattning : Given a tree T, a subtree in T is a subgraph that is a tree itself. The set of subtrees in a tree is related to many important graph parameters, one of which is the mean subtree order. LÄS MER

  3. 7. Stochastic modelling and analysis of early mouse development

    Författare :Sofia Tapani; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; correlation; CUSUM; mouse; non-stationarity; pronucleus; stochastic differential equation; time series; wavelet decomposition; yeast; CUSUM;

    Sammanfattning : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. LÄS MER

  4. 8. Accelerating column generation schemes : applications to routing problems

    Författare :Andreas Westerlund; Oli Madsen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Many integer optimization problems of great practical importance are today attacked with column generation. Merits of column generation is that it enables the use of compact and flexible formulations of many complex optimization problems, and that it often gives rise to good (strong) formulations. LÄS MER

  5. 9. On the Ising problem and some matrix operations

    Författare :Daniel Andrén; Roland Häggkvist; Henrik Eriksson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ising problem; phase tansition; matrix multiplicatoin; matrix inversion; Discrete mathematics; Diskret matematik;

    Sammanfattning : The first part of the dissertation concerns the Ising problem proposed to Ernst Ising by his supervisor Wilhelm Lenz in the early 20s. The Ising model, or perhaps more correctly the Lenz-Ising model, tries to capture the behaviour of phase transitions, i.e. how local rules of engagement can produce large scale behaviour. LÄS MER

  7. 10. Early Vision Optimization: Parametric Models, Parallelization and Curvature

    Författare :Petter Strandmark; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Early vision is the process occurring before any semantic interpretation of an image takes place. Motion estimation, object segmentation and detection are all parts of early vision, but recognition is not. LÄS MER
