Blinkbeteendebaserad trötthetsdetektering : metodutveckling och validering

Electrooculogram (EOG) data was used to develop, adjust and validate a method for drowsiness detection in drivers. The drowsiness detection was based on changes in blink behaviour and classification was made on a four graded scale. The purpose was to detect early signs of drowsiness in order to warn a driver. MATLAB was used for implementation. For adjustment and validatation, two different reference measures were used; driver reported ratings of drowsiness and an electroencephalogram (EEG) based scoring scale.

Fotoindexering på Jämtlands läns museum

The aim of this thesis is to describe the subject indexing of images performed at the provincial museum of Jämtland and to evaluate the inter-indexer consistency at the museum. The main questions are: How are photographs indexed in the database SOFIE foto regarding Outline-codes, subject headings and natural language keywords? How does these procedures compare to research and indexing projects? How consistent are the indexers at the museum when choosing Outline-codes, subject headings and natural language keywords? Answers are sought by reading articles about classification, image indexing, indexing language, indexing consistency and by looking at a number of projects attempting to standardise image indexing practice in Sweden. The indexing practice at the museum is also described. In addition a minor inter-indexing consistency study, based on the subject indexing of ten photographs made by five indexers at the museum, is performed.

"Det är roligt!" : En studie om hur pedagoger använder estetiska lärprocesser i arbetet med naturvetenskap i förskolan

The purpose of this thesis is to investigate how teachers perceive that they work with science in preschool through aesthetic learning processes as tools both in the indoor and outdoor environment and make visible what the educators' underlying beliefs are that affect how they perceive aesthetic learning processes as tools used to deepen children's understanding of different scientific phenomena.This is an interview study using the phenomenographic approach as a means and method to make visible and report on teachers' views on how aesthetic learning processes can be used to extend preschool children's learning about science. The results are analyzed and discussed based on John Dewey's theoretical ideas about children's learning, aesthetics and science.The study clearly shows that teachers' views on aesthetic learning processes and how they can be used in the work whit science is very divided and in some cases unreflective. The most striking results are that teachers often are unaware that they make use of aesthetic learning processes because they have a more limited view of what it is than we have in the paper. All informants have science as a core subject. Their focus of the activity is located at the showing and visualizeing of scientific phenomena and some of them express that they submit the aesthetic learning processes to their colleagues or that they collaborate with someone who has training in some art form.

Operatörsunderhåll : Ett examensarbete om att använda 5S till hjälp för att förbättra operatörsunderhållet

As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.

Other questions relevant for the study are: How important is the social environment for these entrepreneurs and how do they interact with their social environment in order to develop their competence. The study has a qualitative approach.

Utveckling av ett svensk-engelskt lexikon inom tåg- och transportdomänen

This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.

Kunskapsorganisation av ämnesområdet arktektur : Klassifikation eller indexering av samlingarna på en arkitekthögskola?

This thesis analyses the problem of how to organise a multidisciplinary domain of knowledge like architecture. The study is both theoretical and empirical. The theoretical part include discussions of theories of knowledge organisation. Two different principles of classification were examined in relation to the domain itself, as well as in relation to the educational programme at the School of Architecture at Lund University and comparable schools in Sweden. The empirical part is a case study carried out at the School of Architecture at Lund University.

Lek och lärande : en studie om fyra pedagogers syn på den fria leken och dess påverkan på lärandet

The purpose of this study is to find out how four preschool teachers view children?s free playing and its impact on their learning. My main questions are:How do the teachers view the children?s free playing?In what ways does the children?s free playing affect their learning, according to the teachers?This essay is based on a qualitative study in which I have interviewed four female preschool teachers of different ages. I highlight various theories of children?s playing and learning in preschool, by theorists such as Vygotsky, Lillemyr, Knutsdotter Olofsson, Lindqvist, among others.

Pojkkrisen : En studie om pojkkrisens existens utifrån pojkars egna erfarenheter

The Picture book - text and image in interaction. A study of Tove Jansson's picturebook: The Book About Moomin, Mymble and Little MyThis study examines Tove Jansson's picture book The Book About Moomin, Mymbleand Little My, to show relationships between text and image in the narration of thestory. This is done through an analysis based on Ulla Rhedins dissertation The picturebook - towards a theory where the conclusion is that the picture book as book mediumcan be divided in three different picture concepts. The various concepts are; the epicpicture book, the expanding text as well as the genuine picture book. This study hasperformed a text and image analysis showing that the image colors, the differentspreads, landscape scenes and characters' placement, et cetera play a role in placingthe picture book in its concept.Tove Jansson used more than text and image to work out the story of theMoomintroll, Mymble and Little My, there are holes in the picture book that have animportant role, which the analysis will show.

Utvärderingsmodeller, Hur några av Göteborgs universitets- och högskolebibliotek har utvärderat sina IT-tjänster

The main subject with this master thesis is to take a closer look on how some of the university libraries of Gothenburg have evaluated their electronic services (such as search-systems, Internet-based services, CD-ROM etc.). The information technology has made its way into the library field during the past century and needs to be evaluated and quality measured to ensure the best possible service to the users. Since evaluation of electronic services is a new area in the evaluation field, some problems has arisen in terms of choosing evaluation strategies and finding the appropriate performance indicators for the evaluation process. The main questions asked in the thesis are; - Which are the most common theoretical strategies for evaluation? - How do some of the university libraries of Gothenburg perform evaluation in practice? - How does the various strategies for evaluation apply to the context of this thesis? The results show that specific strategies for evaluation aren't used in the reports discussed in this thesis.

Modell av en synkronmaskin för PSCAD/EMTDC med magnetisk mättning i d-led och elektriskt gränssnitt för fältmatare

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

Elevers inställning till matematik : - en jämförande studie av elevers uppfattning av matematikämnet och matematikundervisningen

Based on earlier experiences of mathematics and mathematical learning, both as a student and as a teacher, I became more and more interested in how well the publicly accepted opinions about mathematics as an uninteresting, difficult and ?geeky? subject corresponded to reality. What do Swedish pupils really think about mathematics and is it possible to identify any differences in their attitudes based on the pupils? age?From this point of view the following questions were formulated:·What are pupils? attitudes towards mathematics in grades 3, 6 and 9 and how do they conceive their learning conditions?·Is it possible to detect any differences in the attitudes and preferences depending on the pupils? age?The result of this study compares well with previous studies done in this and overlapping fields and indicates that:·Younger pupils tend to have a better liking of mathematics but with increasing age that interest fades out.·Most pupils, without regard to age, consider mathematics to be one of the most important subjects, despite the fact that many pupils also find mathematics difficult and boring.·For pupils of all ages, the teacher is the most important factor in the learning process. Older students have more specific demands on the teacher for knowledge and pedagogical skills.·A high noise level, talking and disturbances in the classroom are the most bothering elements when it comes to learning mathematics.
