1. Reactive Navigation Methods for Autonomous Robots: Safety, Coordination, and Field Deployment
Sammanfattning : In the new era of intelligent systems, small-scale electronics, and advanced sensors, the application use-cases and operational capabilities of autonomous robots are exponentially increasing. Through their ability to execute complex tasks while relying only on onboard sensors and computation, autonomous field robots are showing promising results in inspection of infrastructure, search-and-rescue or surveillance, maintenance tasks, or in general operations in areas that prove to be dangerous or hazardous for human operators to enter, while also often increasing the efficiency of such tasks.

2. On the utilization of Nonlinear MPC for Unmanned Aerial Vehicle Path Planning
Sammanfattning : This compilation thesis presents an overarching framework on the utilization of nonlinear model predictive control(NMPC) for various applications in the context of Unmanned Aerial Vehicle (UAV) path planning and collision avoidance. Fast and novel optimization algorithms allow for NMPC formulations with high runtime requirement, as those posed by controlling UAVs, to also have sufficiently large prediction horizons as to in an efficient manner integrate collision avoidance in the form of set-exclusion constraints that constrain the available position-space of the robot.

4. Making Connections : Outcomes and the Role of the Therapeutic Relationship in Internet-Delivered Psychodynamic Treatment for Adolescent Depression
Sammanfattning : Major depressive disorder (MDD) is ranked one of the most burdensome disorders for adolescents worldwide. There is an urgent need for accessible interventions, as many adolescents suffering from MDD do not receive treatment. LÄS MER
5. Domestication effects on foraging behaviour : consequences for adaptability in chickens
Sammanfattning : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.
