1. Innovation Resistance : Moving Beyond Dominant Framings
Sammanfattning : Science, Technology and Innovation (STI) research has mainly had an outlook that frames innovation in a pro-innovation, pro-firm, manner. Connected to this perception of innovation is a view of human and non-human resistance as a temporary unwanted response that will eventually be overcome. LÄS MER
2. Weld Pool Simulations
Sammanfattning : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.

3. Computational modeling of oxygen-assisted fracture in nickel-based superalloys
Sammanfattning : Nickel-based superalloys are a commonly used material in applications where high strength is required at high temperatures. A typical such example is jet engines and, in the case of polycrystalline nickel-based superalloys, components like turbine disks. LÄS MER
4. Computational Free-Surface Flows Computational Techniques for Nonlinear Seepage Flow in Porous Media with Free and Moving Boundaries
Sammanfattning : Motion of a viscous fluid interface is encountered in many physical processes in engineering applications. The accurate representation and efficient numerical solution of the fluid interface are crucial problems in simulations of the physical processes in these applications. LÄS MER
5. Grey-box Identification of Distributed Parameter Systems
Sammanfattning : This thesis considers the problem of making dynamic models for industrial processes by combining physical modelling with experimental data. The focus is on distributed parameter systems, that is, systems for which the model structure involves partial differential equations (PDE). Distributed parameter systems are important in many applications, e. LÄS MER
