Att infiltrera, dissekera och korrigera betvingade sinnen : En argumentationsstudie av skriftliga publikationer från Jehovas vittnen
The purpose of this Master?s Degree is to identify and understand different techniques of argumentation in written texts originating from the religious movement Jehovah's Witnesses. The purpose is also to contribute with a theoretical and methodological framework for other scholars. The focal point of the thesis is sexuality and how the authors of the texts try to convince the members to follow the movements' doctrines in this regard. I use a modified version of the well-established grounded theory method.
Implementering av en PSS i Trängslets kraftstation
The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.
Uppbrott från hemmet : en kvantitativ studie av ungdomar som rymmer eller kastas ut hemifrån
Aim:The study's aim is to examine whether and to what extent elementary school pupils aged 13 and 16 report that they ever have been forced to leave home by parents, have run away from home voluntarily or have seriously considered doing so. The aim is also to illuminate which circumstances contribute to these break-ups. Method: A quantitative approach is used; a survey material consisting of 1193 questionnaires is analysed. The data material has been used in earlier studies but the issue addressed here has not been studied earlier. The circumstances analysed are gender, ethnicity, the parents? religious belief and education, living conditions (sharing home with both parents, one of them or none), contacts with professionals (psychologist, school nurse or curator), physical and mental wellbeing, way of upbringing (liberal vs authoritarian) and communication with parents.

Undersökning av optimeringsalternativ för elektrostatlackering
This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..
??då hör inte jag hemma hos er!? : - Att ta avstånd från en religiös gemenskap
This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.
Varför väljs nativeapplikationer istället för hybridapplikationer? : Prestandaskillnader hos hybridapplikationer
The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.
UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk
Lining techniques such as nap bonding and mist lining were developed in the late 20th century and
have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability
of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown
advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced,
which can be advantageous for more sensitive paintings. These lining techniques have been included
in several studies where reversibility, minimal intervention and respect for the individual requirements
and problems of each object have been the focus. The adaptability of the methods has been confirmed
and to further explore the adaptability, this study consists of three simpler application techniques with
the adhesive Lascaux 303 HV on mockups.

Investeringsbedömningstekniker i praktiken: En fallstudie om Divisionen
The purpose of this thesis is to investigate how theoretical investment appraisal techniques are applied in an investment driven company, regarding investments in fixed assets. The aim is also to investigate on what grounds the choices of techniques are justified, and what consequences these choices have on the overall investment appraisal. The study is designed as a case study of Divisionen, a production unit of a market leading company in Sweden, which is kept anonymous in this thesis. The empirical data consists of interviews with company employees and internal documents, including decision support for seven approved investment projects. The interviewees were chosen based on their role in the investment decision making process.

My purpose with this thesis has been to find out how to choreograph a fight sequence in ananimated movie. With the help of professional stuntmen and dancers, I have tried to findmethods and techniques used on stage and in live-action film and apply those to animatedfilms. To successfully identify the techniques used, I conducted a number of interviews andanalyzed literature that deals with the subject of fight choreography. By the analysis of themethods provided by the choreographers and selected parts of the literature, I have compiled anumber of steps I recommend 3D animators should to take in their efforts to create their ownfight choreography..
Vetenskapsteoretiska och metodologiska perspektiv på tidsgeografiska visualiseringsmodeller. -En fallstudie i samhällsvetenskaplig visualisering
In the history of scientific visualization techniques there is a lack of social science practices and methodologies. The advent of modern computer graphics brought the use of visualizations into a whole new era, but even though the tools by which such modern visualizations are created become easier to access and use, the lack of social science researchers harvesting the benefits of such tools still remain. This ease of use, increase in power and accessibility plus the ever growing need within the natural sciences to augment the human senses has further complicated the relationship between scientific methodologies, validity, reliability and the use of visualization techniques. This relationship must be explored, demystified and understood in order to fully grasp the impact of visualization practices when incorporated into any given scientific method. Within the social sciences there is one example of a tradition that has since its conception carried within it a graphical notion and a visualization practice.
Trakealkollaps hos shetlandsponnyer : effekt på prestation och lungfunktion
Trakealkollaps är relativt ovanligt förekommande hos hästar men är något vanligare hos småvuxna ponnyraser. Sjukdomen har ett progressivt förlopp och är ofta långt framskriden innan respirationssymtom som missljud, hosta och dyspné uppkommer. De tillgängliga behandlingsalternativen ger sällan tillfredsställande resultat och prognosen vid höggradig kollaps med grava symtom får anses som dålig. Syftet med den här studien var att undersöka om och i så fall i vilken grad trakealkollaps påverkar hästens användbarhet, detta gjordes genom att undersöka om det fanns någon skillnad i arbetstolerans och lungfunktion mellan en grupp friska shetlandsponnyer och en grupp shetlandsponnyer med trakealkollaps. Den friska gruppen bestod av tio ponnyer och gruppen med kollaps av fyra ponnyer, varav tre hade trakealkollaps av grad 3 och en av grad 2.
Användarinvolvering i ett systemutvecklingsprojekt -Är det effektivt?
In most software engineering project, users are only involved in the beginning of the project as a help to design the requirements specification but users can be involved after this phase too, but is it effective to do so? With this report we would like to investigate how effective it is to involve users after the requirements specification has been written and approved. To find out how effective it is to involve the users we try some fast and simple involvement techniques on a quite far gone project. These techniques include ethnographic studies, prototypes and surveys. We also interviewed a couple of people who work with usability and finally delivered a report with our results to them to find out if they found our result relevant.
