2. 1. Modelling Sexual Interactions : Sexual behaviour and the spread of sexually transmitted infections on dynamic networks

   Author : Disa Hansson; Tom Britton; Fredrik Liljeros; KaYin Leung; Janneke Heijne; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical modelling; Sexually transmitted infections; Egocentric network analysis; Dynamic networks; Sexual behaviour; HIV; Statistical inference; Mathematical Statistics; matematisk statistik;

   Abstract : In this thesis we develop statistical and mathematical models to study different factors of relevance for the spread of sexually transmitted infections (STIs). Two special interest groups for STI interventions are considered: sexually active youths and men who have sex with men (MSM). READ MORE

4. 2. Modelling Evolution : From non-life, to life, to a variety of life

   Author : Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

   Abstract : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. READ MORE

5. 3. Measurements and Modelling of Low-frequency Disturbances in Induction Machines

   Author : Torbjörn Thiringer; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; induction machine; measurements;

   Abstract : in this thesis the low-frequency dynamic behavior of the induction machine is analyzed. disturbances in the shaft torque and supply voltage are investigated theoretically, The calculated response to shaft torque disturbances is verified with measurements on a 15 kW machine. READ MORE

6. 4. Modes of Mathematical Modelling : An analysis of how modelling is used and interpreted in and out of school settings

   Author : Peter Frejd; Christer Bergsten; Jonas Ärlebäck Bergman; Rudolf Strässer; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The relevance of using mathematics in and for out-of-school activities is one main argument for teaching mathematics in education. Mathematical modelling is considered as a bridge between the mathematics learned and taught in schools and the mathematics used at the workplace and in society and it is also a central notion in the present Swedish mathematical syllabus for upper secondary school.

7. 5. Mathematical Modelling of Cell Migration and Polarization

   Author : Adam Malik; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Cell migration plays a fundamental role in both development and disease. It is a complex process during which cells interact with one another and with their local environment. Mathematical modelling offers tools to investigate such processes and can give insights into the underlying biological details, and can also guide new experiments. READ MORE
