21. Land Mine Detection using Dual-Band Electro-Optical Sensing
Sammanfattning : This thesis addresses the detection of buried and partially occluded land mines using electro-optical sensing. According to the Red Cross approximately 10000 people are killed and another 30000 are injured each year in mine related accidents. LÄS MER
22. Agency and Artefacts : A cognitive semiotic exploration of design
Sammanfattning : This thesis investigates the role of artefacts in relation to human agency and design within a cognitive semiotics framework. It deals with questions such as What is agency? What are artefacts and how does agency relate to them? What kind of intentions are involved in the activity of designing? What is human-specific with respect to agency and design? How can the origins and evolution of design be explained? Addressing these questions, the thesis proposes a layered model of agency for explaining the relations between different grades of agentive complexity. LÄS MER
23. Stem Cell Plasticity Controlling Neuronal Differentiation Prior to Cell Transplantation
Sammanfattning : Parkinson's disease (PD) is the second most common neurodegenerative disease and affects 2% of the population over 65 years of age. The disease is characterized by the progressive loss of dopaminergic neurons. Over time, symptoms increase and, in particular, lead to a dramatic slowness of movements. LÄS MER
24. Optimal strategies and information in foraging theory
Sammanfattning : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. LÄS MER
25. Conjugate priors for Bayesian object tracking
Sammanfattning : Object tracking refers to the problem of using noisy sensor measurements to determine the location and characteristics of objects of interest in clutter. Nowadays, object tracking has found applications in numerous research venues as well as application areas, including air traffic control, maritime navigation, remote sensing, intelligent video surveillance, and more recently environmental perception, which is a key enabling technology in autonomous vehicles.
