16. Mechanicus : Performing an Early Modern Persona
Sammanfattning : This thesis studies mechanics as a means of making men, rather than machines. Drawing on Swedish sources from 1700–50, it approaches mechanics as an exercise of a virtuous subject, known to his contemporaries as the “mechanicus”. LÄS MER
17. Two Problems in non-linear PDE’s with Phase Transitions
Sammanfattning : This thesis is in the field of non-linear partial differential equations (PDE), focusing on problems which show some type of phase-transition. A single phase Hele-Shaw flow models a Newtoninan fluid which is being injected in the space between two narrowly separated parallel planes. LÄS MER
18. Numerical methods for inverse heat conduction problems
Sammanfattning : In many industrial applications one wishes to determine the temperature history on the surface of a body, where the surface itself is inaccessible for measurements. The sideways heat equation is a model of this situation. LÄS MER
19. Convergence analysis of domain decomposition methods : Nonlinear elliptic and linear parabolic equations
Sammanfattning : Domain decomposition methods are widely used tools for solving partial differential equations in parallel. However, despite their long history, there is a lack of rigorous convergence theory for equations with non-symmetric differential operators. This includes both nonlinear elliptic equations and linear parabolic equations. LÄS MER
20. Topics in the mean-field type approach to pedestrian crowd modeling and conventions
Sammanfattning : This thesis consists of five appended papers, primarily addressingtopics in pedestrian crowd modeling and the formation of conventions.The first paper generalizes a pedestrian crowd model for competingsubcrowds to include nonlocal interactions and an arbitrary (butfinite) number of subcrowds.
