1. 1. Data driven mathematical models for policy making

   Författare :Betty Nannyonga; David Sumpter; JYT Mugischa; LS Luboobi; Tom Britton; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; Matematik med inriktning mot tillämpad matematik; Mathematics with specialization in Applied Mathematics;

   Sammanfattning : This thesis consists of two papers. 1. Betty Nannyonga, D.J. LÄS MER

3. 2. Using an Artificial Ecosystem to Understand Living Ecosystems

   Författare :Yu Liu; David Sumpter; Philip Gerlee; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Biology; Mathematical Modeling; Emergence; Ecosystem Evolution; Community Ecology; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Community ecosystems at very different levels of biological organization often have similar properties. Coexistence of multiple species, cross-feeding, biodiversity and fluctuating population dynamics are just a few of the properties that arise in a range of ecological settings. LÄS MER

4. 3. Reinforcement in Biology : Stochastic models of group formation and network construction

   Författare :Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. LÄS MER

5. 4. Non-linear dynamic modelling for panel data in the social sciences

   Författare :Shyam Ranganathan; David JT Sumpter; Oliver Johnson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamical systems; stochastic models; Bayesian; panel data; social sciences; development; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Non-linearities and dynamic interactions between state variables are characteristic of complex social systems and processes. In this thesis, we present a new methodology to model these non-linearities and interactions from the large panel datasets available for some of these systems. LÄS MER

7. 5. Mathematical models of biological interactions

   Författare :Linnéa Gyllingberg; David J.T. Sumpter; Kolbjörn Tunström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

   Sammanfattning : Mathematical models are used to describe and analyse different types of biological interactions.  From self-propelled particle models capturing the collective motion of fish schools to models in mathematical neuroscience describing the interactions between neurons to individual-based models of ecological interactions.
