1. Integration of graphene into MEMS and NEMS for sensing applications
Sammanfattning : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. LÄS MER
2. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies
Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER
3. Residual Stress Distributions in Additively Manufactured Parts : Effect of Build Orientation
Sammanfattning : Additive manufacturing (AM) of parts using a layer by layer approach has seen a rapid increase in application for production of net shape or near-net shape complex parts, especially in the field of aerospace, automotive, etc. Due to the superiority of manufacturing complex shapes with ease in comparison to the conventional methods, interest in these kinds of processes has increased.

4. Litteracitet genom interaktion
Sammanfattning : The dissertation Litteracitet genom interaktion [‘Literacy through Interaction’] spotlights how literacy interaction can work in the primary school’s multilinguistic environments. It investigates conversations that occur in and around teaching about writing. LÄS MER
5. Controlling the Roll Responses of PCTC's
Sammanfattning : Modern Panamax Pure Car and Truck Carriers (PCTC) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this licentiate thesis aims at enhancing the predictability and control of these critical roll responses. LÄS MER
