16. Predictive action in infancy : Evidence of early prospective behavior
Sammanfattning : How do young infants understand and act on their constantly changing environment? An action perspective on motor development was taken into account. The present thesis investigated perception guided predictive action in 6-month-old infants, namely, head tracking and reaching for an object moving on a pre-defined trajectory, linear or nonlinear, fully visible or partially occluded.

17. Minkowski Measure of Asymmetry and Minkowski Distance for Convex Bodies
Sammanfattning : This thesis consists of four papers about the Minkowski measure of asymmetry and the Minkowski (or Banach-Mazur) distance for convex bodies.We relate these two quantities by giving estimates for the Minkowski distance in terms of the Minkowski measure. LÄS MER
18. Development of a PKM control system by design, modelling, simulation and integration
Sammanfattning : PKM (ParallelKinematicMechanism) machines have received increasing interestfrom industries. Nevertheless, they didn't turn out goodresults in control performances as desired. One of the reasonsis the unsuitability of the available control systems for theparallel mechanisms.This thesis presents a process to develop a PKM controlsystem. LÄS MER
19. Studies of Hydrogenations and Isomerizations of Olefins and Alkylations of Amines Using Iridium Catalysts
Sammanfattning : This thesis describes three types of reactions that were carried out using iridium catalysts.The first type is the iridium-catalyzed asymmetric hydrogenation of olefins. In paper I, the preparation of a new type of bicyclic thiazole-phosphine based iridium complex was described. LÄS MER
20. Electrochemical Capacitors for Miniaturized Self-powered Systems
Sammanfattning : Miniaturized self-powered systems with harvest-store-use architectures have been recognized as a key enabler to the internet-of-things (IoT), and further the internet-of-everything (IoE), 5G communication and tactile internet. Electrochemical capacitors (ECs), also known as supercapacitors, are promoted to be the energy storage component in such systems, because of their advantages such as an almost limitless cycle life that is ideal for the vision of “fit-and-forget” maintenance-free networks.
