21. Integrated Control of Heat Pumps
Sammanfattning : The purpose of the work presented in this thesis is to investigate the potential and prerequisites for improved energy efficiency of heat pump systems using efficient components and proper methods for optimisation of operation. The background is that several investigations have reported on possibilities for increased energy efficiency of heat pumps if variable-speed capacity control is used instead of conventional on/off control.

22. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties
Sammanfattning : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. LÄS MER
23. Barnehagens relasjonelle verden - små barn som kompetente aktører i produktive forhandlinger
Sammanfattning : The present study investigates the negotiations that take place in play among the youngest children in preschool. What are their negotiations about? How do they negotiate? What kinds of strategies do they use during their negotiations? The study has its focus on learning about fellowship through practice and experience in the negotiations that take place among the youngest preschool children. LÄS MER
24. Quasi-analytical Modelling and Optimisation Techniques for Transport Aircraft Design
Sammanfattning : The research work presented here focuses on the subject oftransport aircraft design at the pre-design or conceptuallevel. The primary topics addressed are: (1) generation of avast array of new quasi-analytical expressions to permit aconceptual treatment of commercial and business transportaircraft with adequate sensitivity for more advanced tradestudies; (2) review and adoption of a method to predictstability and control characteristics (using the Mitchellmethod); (3) a study of the relative merits between variousmethods in facilitating an expedient and robust constrainedmulti-objective optimisation result within the context oftraditional conceptual design problems (Genetic Algorithms andNelder-Mead Simplex search); (4) creation of a software packageas a new and unique conceptual tool that permits the generationof design proposals in an accurate yet expeditious manner; and,(5) practical demonstration of the new conceptual designsoftware package by undertaking some actual aircraft designproposals.

25. Läraridentitet och lärararbete : Fem livsberättelser
Sammanfattning : In the dissertation I want to highlight how teacher identity takes form in different historical, social and local settings. The forming of a professional identity is one of the aims of this study. The other aim is to examine how teachers describe their work. Work in this context means everything a teacher does. LÄS MER
