1. Micro-mechanical mechanisms for deformation in polymer-material structures
Sammanfattning : In this thesis, the focus has been on micro-mechanical mechanisms in polymer-based materials and structures. The first part of the thesis treats length-scale effects on polymer materials. Experiments have showed that the smaller the specimen, the stronger is the material. LÄS MER
2. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation
Sammanfattning : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. LÄS MER
3. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements
Sammanfattning : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. LÄS MER
4. Context-Based Micro-Training : Enhancing cybersecurity training for end-users
Sammanfattning : This research addresses the human aspect of cybersecurity by developing a method for cybersecurity training of end-users. The reason for addressing that area is that human behaviour is widely regarded as one of the most used attack vectors. LÄS MER
5. Dialectics of Negotiagency : Micro Mechanisms in Children’s Negotiation in Play Activity
Sammanfattning : This study is about the children in a fourth and fifth grade Swedish primary school class and their play during breaktimes. The study takes the theoretical point of departure in seeing children’s breaktime play as a cultural historical activity. LÄS MER
