  • Age heaping in population data of emerging countries 

    Barajas Paz, Andres (Heriot-Watt University Mathematical and Computer Sciences, 2022-02)
    Mortality analyses have commonly focused on countries represented in the Human Mortality Database that have good quality mortality data. In this thesis, we address the challenge that, in many countries, population and ...

  • Non-linear partial differential equations of kinetic type 

    Lazaridou, Christina (Heriot-Watt University Mathematical and Computer Sciences The University of Edinburgh, 2022-02)
    This thesis is concerned with the analytical study of non-linear partial differential equations (PDEs) of kinetic type which admit multiple stationary solutions. We consider a kinetic model which is given by a non-linear ...

  • Linear and nonlinear wave equation models with power law attenuation 

    Baker, Katherine (Heriot-Watt University Mathematical and Computer Sciences, 2022-02)
    Motivated by the need to model high intensity focused ultrasound in lossy media we study linear and nonlinear wave equations that contain non local time fractional derivatives, whose inclusion in our models incorporates ...

  • A pseudodifferential approach to the fractional Laplacian and magnitude 

    Louca, Nikoletta (Heriot-Watt University Mathematical and Computer Sciences, 2022-01)
    In this thesis we consider two problems related to the fractional Laplacian. One of these is the study of the singular behaviour of solutions of boundary value problems for the fractional Laplacian in smooth and polygonal ...

  • Multi-population and factor-based mortality analytics 

    Wen, Jie (Heriot-Watt University Mathematical and Computer Sciences, 2022-01)
    In this thesis, I develop a model that uses socio-economic characteristics to explain differences in the mortality of different populations. This thesis has two main objectives. Firstly we look at mortality data of ...
