An interesting class of intelligent tutoring systems are systems that are able to detect and recognize affective responses and states in students, and use such data to adapt its feedback, guidance and instruction. The article presents affective responses and states considered relevant for learning, and methods that have been proposed or used to detect such responses and states. We focus on the aff

Popular Abstract in Swedish Det finns en föreställning att kvinnor tills nyligen varit åsidosatta inom historieforskningen, något som hävdats bland annat inom kvinno- och genderteoretisk forskning. Mot bakgrund av en genomgång av svenska avhandlingar i historia argumenterar jag för att utvecklingen måste ses i ljuset av historieforskningens utveckling. Det finns en relation mellan vilka fenomen foI am studying the portrayal of women in Swedish dissertations of history from 1890 to 1995. Inspired by Pierre Bourdieu I interpret the production of knowledge as an effect of the rivalry between researchers concerning the dominate positions within the field of history. One strategy in order to reach these positions is to focus on phenomena that previous research has not paid attention to. To show

Popular Abstract in Swedish Olika toleransmekanismer kontrollerar immunsystemets aktivitetThe immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. This thesis work is based on investigations of different tolerance mechanisms induced in CD4+ T lymphocy

Antenna current optimization offers performance bounds and suggestions for the distribution of the desired antenna currents. Many current optimization problems can be formulated as convex optimization problems that are solved efficiently with explicit error bounds. The formulations as convex optimization problems are also illuminating as they can easily be generalized to specific antenna problems

Unsupported vanadium antimonate catalysts with Sb/V ratios of 1 and 5 and samples with the latter ratio supported on alumina were studied in toluene and propane ammoxidation to benzonitrile and acrylonitrile, respectively, and were characterized by X-ray photoelectron spectroscopy (XPS) analysis before and after catalytic tests. Activity data for toluene ammoxidation suggest that excess antimony w

Popular Abstract in Swedish Professionella balettdansare börjar vanligtvis dansa balett redan vid 8–10 års ålder; pojkar ett par år senare än flickor. Det finns flera utbildningsvägar både i Sverige och utomlands. De flesta börjar sin yrkeskarriär vid 18–20 års ålder. I Sverige är pensionsåldern för institutionsdansare 41–44 år, då man efter 20 års anställning vid svenska institutioner kan få maxiBallet dancers have been shown to have frequent problems with the musculoskeletal system, but little is generally known about the prevalences of musculoskeletal disorders and about working conditions of professional ballet dancers in Sweden. The aims of the thesis were: to analyse the prevalence, location and recurrence of self-reported musculoskeletal disorders (pain) in professional ballet danc

The purpose of the present study was to demonstrate possible effects on Collembola populations by changes in tree composition in natural birch forest in coastal North Norway. In the study area (Dønnes, Nordland County) parts of the natural mixed birch forest has been replanted with Norway spruce and Sitka spruce. Soil samples were collected in June and October 2004. A total of 52 species of Colle

A combustion system was developed to burn a low value gas in the VT4400 IGT engine demonstrator. The combustor was designed in an engine configuration consisting of a single LCV combustor operating in combination with six LP combustors.
