1. Effects of manufacturing chain on mechanical performance : Study on heat treatment of powertrain components
Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER
2. Computational modelling of rail manufacturing
Sammanfattning : The thesis deals with simulation of rail manufacturing. During the manufacturing process residual stresses arise in the rail, primarily due to cooling and straightening. These stresses can affect product performance, for example fatigue characteristics. Therefore it would be desirable to be able to predict these in an efficient way. LÄS MER
3. The Structural Basis of the Control of Actin Dynamics by the Gelsolin Superfamily Proteins
Sammanfattning : Rearrangement of the actin cytoskeleton occurs in a variety of cellular processes and structures and involves a wide spectrum of proteins. Among these, the gelsolin superfamily proteins (GSPs) control actin organization by severing filaments, capping filament ends and bundling filaments. LÄS MER
4. Development of a Mechanical Model for Rear Impacts: Evaluation of Volunteer Responses and Validation of the Model
Sammanfattning : The objective of this research has been to develop a biofidelic crash-test dummy to facilitate design of seat systems with enhanced occupant protection in rear-end collisions. These frequent collisions may cause soft-tissue neck injuries to occupants in struck vehicles. LÄS MER
5. Anadromous Pike in the Baltic Sea
Sammanfattning : The pike (Esox lucius) is a major predator and top-down regulator in the Baltic Sea where it exists in two sympatric forms. One spawn in streams and rivers and the other one spawn in the sea. During the last decades, the habitats for both of these forms have developed in a negative way. LÄS MER
