36. On Tailbiting Codes from Convolutional Codes
Abstract : Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. READ MORE

37. Ultrafast Structural and Electron Dynamics in Soft Matter Exposed to Intense X-ray Pulses
Abstract : Investigations of soft matter using ultrashort high intensity pulses have been made possible through the advent of X-ray free-electrons lasers. The last decade has seen the development of a new type of protein crystallography where femtosecond dynamics can be studied, and single particle imaging with atomic resolution is on the horizon.

38. Efficiency Enhancement Techniques for Free-Electron Lasers
Abstract : The central question addressed in this thesis is how to make the free-electron laser (FEL) more efficient. In recent years, coherent diffraction imaging provides an important motivation for efficiency enhancement. This is because a more efficient FEL process enables converting a larger fraction of the electron beam's power into optical power. READ MORE

39. Expanding the use of contract inspections in construction : An approach to inter-project knowledge diffusion?
Abstract : This licentiate thesis presents a taxonomic approach to classification of defect information in construction projects. A conceptual model, based in a frame of reference consisting of the concepts of Continuous Improvement, Performance Measurement, Knowledge Management, as well as the current Quality Management regime of the industry helps to understand how the use of Contract Inspections can be developed towards facilitating inter-project knowledge diffusion and continuous improvement in construction.

40. Building Physics Tools: Needs, Use and the Lack of Use in the Building Process. Modelling Non-Isothermal Moisture Flow and Frost Penetration
Abstract : Despite advances in material science, computers and building technology, building failures related to building physics continue to occur. These failures range from a building not meeting its energy use target to a building causing people to become ill from exposure to various chemicals or biological organisms. READ MORE
