1. Simplified models for emission formation in diesel engines during transient operation
Sammanfattning : The work presented in this thesis is the result of the KTH CICERO project “Dynamic Engine Performance” in which the main objective was to develop simple models foremission formation. The demand for such models is increasing, mainly due to the tightening emission legislation for diesel engines which has lead to more complex engines and thereby more laborious development and calibration processes.

2. Undervisnings- och utbildningsplanering - för vem? : En studie av ingenjörsutbildning vid en svensk högskola
Sammanfattning : This dissertation points at some of the consequences of the changes in the economic and social conditions of the second half of the twentieth century that have had a great influence on higher education. A growing number of students are attending our universities and at the same time the Government is asking for greater quality and efficiency in education. LÄS MER
3. Pedagogers arbete med förskolebarns inflytande : En demokratididaktisk studie
Sammanfattning : I licentiatuppsatsen Pedagogers arbete med förskolebarns inflytande undersöks vad arbetet med förskolebarns inflytande kan innebära i praktiken. Genom observationer på två förskoleavdelningar samt intervjuer med pedagogerna, besvaras frågor om vilket innehåll, vilka arbetsformer och vilka dilemman som kommer till uttryck i detta arbete.

4. Fundamental friction phenomena and applied studies on tribological surfaces
Sammanfattning : This thesis is based on two different projects, one more focused on applied research and one on more basic research. The first project examines the po- tential of nitriding as an alternative to case hardening in tribologically loaded components while the second project involves micro scale studies of the relations between roughness, transfer and friction between metals.

5. Estimation and Prediction in Interdependent Systems in the Presence of Specification Errors
Sammanfattning : Mult i relät ional models involving simultaneously dependent linear equations are often employed in prediction and regulation of economic systems. The prediction purposes focus their attention on the reduced form of the model, relating each endogenous variable to exogenous variables, predicted outside the system. LÄS MER
