Vuxnas ansvar - en studie om barns möjligheter till delaktighet och inflytande i utformandet av förskolans miljö

This essay aims to investigate how students raised in Jehovah's Witnesses have experienced their career counseling during their middle and high school education. My main objectives are, based on the testimonies of former Jehovah's Witnesses, to investigate how career counselors can find a strategy to approach these students in a non-threatening way. I also try to take into account the contextual elements which are of great importance when counseling students raised as Jehovah's Witnesses. A qualitative study has been carried out with five informants with a background in the movement. The material has then been analyzed using a qualitative, narrative method.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Att hjälpa alla elever nå målen : En holistisk och kontextuell specialpedagogisk studie om lärarnas önskemål och behov

There is a discrepancy between national school guidelines towards inclusive education, and the current political trend towards economic efficacy, that may be problematic for teachers. The aim of this contextual study is to formulate a contextual understanding of the participating teachers? perceptions of their effort to help all their students achieve the goals set forth by school curricula, and use this understanding for the purpose of suggesting points of entry for special needs educators´ guidance of teachers? practices towards more inclusive education.Information was gathered by sending an extensive web questionnaire to all teachers within a given headmaster´s administration, sending web questionnaires to a majority of third grade students taught by those teachers, conducting interviews with a few of the participating teachers as well as with the special needs educators, carrying out a classroom observation, and gathering additional information concerning working conditions and social interactions.The data gathered in this case study has been subjected to an analytical process comprising of an assessment of the degree of inclusive approach, using the Inclusive Approach through Participation as well as the Framework of Participation, technical triangulation of all data post the inclusive assessment, and analysis of context by the Ecology of Human Development/the Bioecological Theory.The analytical process has resulted in a contextual description that has enabled me to suggest possible points of entry to be used in special needs educators? guidance of teachers? practices towards inclusive education. The degree to which there exists a collegial sense of security, varied forms of teacher-student interactions, collegial cooperation, pedagogical discussions, a dialogue in search of mutual understanding, and consequent follow-ups appears, in the light of the limited selection of participants, as relevant to these teachers ability to help their students.Further research is needed to identify valid points of entry for special needs educators? guidance of teachers? practices towards inclusive education.

När en roman blir teveserie: Om Jane Austens aktualisering i och med 1995 års teveinspelning av Pride and Prejudice

The aim of this Masters thesis is to examine how Jane Austens Pride and Prejudice, first published in 1813, was established in different literary orbits after the transformation to the television medium in 1995. I also want to find out what this adaptation meant for the popularity of Jane Austen, the circulation of her works and the rebirth of her authorship. It has furthermore been of interest to discuss the reasons why Jane Austen and her works became so popular. Questions posed in the study are: What has the 1995 production of Pride and Prejudice meant for the spreading of Jane Austens literary work and for the rebirth of her authorship? How has Pride and Prejudice moved between the literary orbits after it became a television-serial in 1995? Why did the circulation get the character it got in the 1990s? In order to find feasible answers to these questions I have used Hans Hertels model of the five literary orbits as theoretical starting point.

Den interaktiva djurparken / The interactive zoo

The purpose of this thesis project is to develop a set of interactive digital solutions designed to enhance the interest and knowledge intake of visitors at Skånes Djurpark (Zoo of Scania) in Höör. The project was carried out in collaboration with Skånes Djurpark and representatives from its visitors. Our thesis is based on academic works in the fields of interaction design, exhibit design and contextual learning. Ethnographical field studies have been conducted at Skånes Djurpark with additional field studies at Tropikariet in Helsingborg, Copenhagen Zoo and Regionmuseet Kristianstad. Existing information signs in Skånes Djurpark are primarily image- and textbased, forcing visitors to divert their attention from the different species of Nordic animals that inhabit the zoological park.

Diagnostisering av projekt : En studie med utgångspunkt från SPA-ramverket

The work in project has been around since humans began to hunt in groups, building bridges or building of the Great Wall of China. In 1960- and 70´s, the word project got their value it has today. A project means a work done during a decided time, with decided economy and non-recurring nature (Jansson and Ljung 2004). The projects had a general analytical model. It was used for all projects the organization engaged.

Modellering av indunstning på Södra Cell Mönsterås

Evaporation is a part of the chemical recovery department at wood pulping mills. The purpose of evaporation is to remove water from the black liquor, which makes the liquor combustible. The process is very energy demanding, and having a well-functioning model of the system is of greatest interest. The model can then be used to study energy consumption and to test different control strategies. Two models have been developed during the master thesis.

Kan inställningen till en IT-artefakt förändras genom användarmedverkan i designprocessens tidigaste stadium?

Ansatsen; Deltagande design inom MDI förespråkar att användare är med under hela designprocessen, även under det tidigaste skedet, före det har skissats på någon prototyp över huvudtaget. Medverkan innebär då att användarna får klargöra sina behov, åsikter och önskemål om en produkt. En speciell deltagarteknik har utvecklats för att göra detta möjligt och heter Contextual inquiry. I detta arbete har tekniken tillämpats på hyresgäster inom Skövdebostäder och har gällt produkten elektronisk anslagstavla. Hypotesen har varit att inställningen till en produkt är mer positiv när användare har deltagit i det tidigaste stadiet i designprocessen och skulle då förklaras med hjälp av ett psykologiskt "fenomen" som kallas Hawthorne-effekten.

Demonstrationsprojektets roll i framväxten av ny teknik: Fallstudier av två vindkraftprojekt

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.

Modellering av en panna med rörlig rost :  

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Användarorienterad design av anestesisystem

In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Strokekedjan från början till slut : En etnografisk studie om farlighet och tid i en akut vårdkedja

Varje år drabbas 30 000 svenskar av stroke, vilket innebär stora personliga omställningar och stora kostnader för samhället. Den mest effektiva behandlingen, trombolys, måste ges så snart som möjligt för att ha god effekt.  Samtidigt som det är av största vikt att ta reda på om patienten har några differentialdiagnoser som gör behandlingen riskfylld.Den här studien undersöker hur strokekedjan går till och vilka faktorer som påverkar beslutsfattandet. Studien är baserad på etnografiska fältstudier på fyra svenska sjukhus och materialet är analyserat med metoder från sammansatta kognitiva system och målorienterad design. Resultaten visar att trots olika organiserade strokekedjor på de olika sjukhusen är processerna desamma och direkt kommunikation är mest framgångsrik för att effektivt sprida information mellan dem. Neurologjouren är viktig roll som, liksom resten av aktörerna i strokekedjan, ständigt balanserar sitt beslutsfattande mellan effektivitet och grundlighet.

Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg

The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.
