1. Lärares och elevers interaktion i klassrummet : Betydelse av kön, ålder, ämne och klasstorlek samt lärares uppfattningar om interaktionen
Sammanfattning : The aim of this thesis is to investigate classroom interaction. Of central importance are the following questions; Does gender of pupil, gender of teacher, age of pupils, subject taught and class size have any importance for the classroom interaction? What conceptions of interaction with pupils do teachers have?Data have been collected by two different methods – structured classroom observations and focus groups. LÄS MER
Sammanfattning : I studied the effects of temperature, pH, competition and predation on Eurasian perch (Perca fluviatilis) in 30 lakes in Norway during 1981-2001. The study lakes were situated in two different areas in southern Norway; four lakes in Aust-Agder county in southernmost Norway were explored during 1981-1984 and 26 lakes in Hedmark county in south-eastern Norway were investigated during 1992-2001.

4. Machine Learning Methods Using Class-specific Subspace Kernel Representations for Large-Scale Applications
Sammanfattning : Kernel techniques became popular due to and along with the rising success of Support Vector Machines (SVM). During the last two decades, the kernel idea itself has been extracted from SVM and is now widely studied as an independent subject. LÄS MER
Sammanfattning : This thesis contributes to the field of machine vision and the theory of the sampling of particulate material on conveyor belts. The objective is to address sources of error relevant to surface-analysis techniques when estimating the sieve-size distribution of particulate material using machine vision. LÄS MER
