1. Turbulence Modelling of Flows Related to Wall-Cooling Applications
Sammanfattning : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.

2. Filtering and modelling for automotive safety systems
Sammanfattning : This thesis makes five important contributions to the development of an automotive safety system: filtering algorithms, three modelling frameworks concerning the usage of radar detections in tracking, vehicle motion, and decision-making for intervention decisions, and finally the implementation architecture.In the filtering context, we have developed a new sigma-point method for estimating the moments of a transformed Gaussian random variable.

3. Biomechanical analyses of flywheel resistance exercise : From a space- and ground-based perspective
Sammanfattning : Astronauts suffer degradation of postural muscles and weight-bearing bones during long-duration spaceflight. Resistance exercise is used as a primary countermeasure against these degradations. LÄS MER
4. Modelling of Traffic Loads on Bridges Based on Measurements of Real Traffic Loads in Sweden
Sammanfattning : This thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. LÄS MER
5. Intrinsic Formation and Macroscopic Intervention in Multi-agent Systems
Sammanfattning : In this dissertation, we study two problems within the field of the multi-agent systems theory. One is the formation control for multiple reducedattitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. LÄS MER
