21. Synthesis of Conjugated Polymers: Photoactive Substances for Photonic Devices
Sammanfattning : Synthesis and characterization of conjugated polymers are the subject of this thesis, the goal of which is to synthesize polymers with properties that will make them suitable as the active materials in applications such as light-emitting diodes and microcavity laser devices. The two classes of conjugated polymers studied are poly(p-phenylenevinylenes) (PPVs) and polyfluorenes (PFs). LÄS MER

23. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms
Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER
24. Towards a Framework for Efficient Use of Virtual Reality in Urban Planning and Building Design
Sammanfattning : This thesis mainly deals with the question on how Virtual Reality (VR) simulations can become a communication tool that is integrated in the urban planning and building design process. The work has investigated both technical and usability aspects of the VR technology and identified challenges encountered when trying to implement VR as a natural communication platform in urban planning and building design.
