  2. 1. On initiation of chemically assisted crack growth and crack propagation paths of branching cracks in polycarbonate

    Author : Ulf Hejman; Malmö högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; stress corrosion cracking; polycarbonate; dissolution; branching; experiment; finite element modelling; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; branching.;

    Abstract : Stress corrosion, SC, in some cases gives rise to stress corrosion cracking, SCC, which differs from purely stress intensity driven cracks in many aspects. They initiate and grow under the influence of an aggressive environment in a stressed substrate. They grow at low load and may branch. READ MORE

  4. 2. Two-Sex Branching Populations

    Author : Ali Falahati; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; branching process; martingale; population dynamics; two-sex; bisexual; coupling method; martingale;

    Abstract : We introduce a Two-Sex Galton-Watson Branching Process, to study the dynamics of two-sex populations. It allows individuals to interact with each other in order to form couples (or mating units), and each of these couples produces children for the new generation. READ MORE

  5. 3. Multi-trait Branching Models with Applications to Species Evolution

    Author : Daniah Tahir; Ingemar Kaj; Martin Lascoux; Asger Hobolth; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Markov models; branching processes; density dependence; discrete traits; species trees; diversification rates; diffusion approximation;

    Abstract : This thesis provides an analysis of the evolution of discrete traits and their effect on the birth and survival of species using the theory of supercritical, continuous time Markov branching processes. We present a branching modeling framework that incorporates multi-trait diversification processes associated with the emergence of new species, death of existing species, and transition of species carrying one type of a trait to another.
