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.

Simulation driven design : An iterative approach for mechanical engineers with focus on static analysis

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

En fordonsförares upplevelse av accelerationer som grund för en effektiv simuleringsmodell

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

Utvalda riskmått och funktioner har dessutom undersökts och förklarats för tre olika mjukvarupaket designade för att beräkna risk. Skillnader i programmen har lyfts fram, dissikerats och diskuterats..

Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8

The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

Modellering av Panna 5 Mälarenergi AB : utveckling av en beräkningsmodell med simuleringsverktyget IPSEpro

Heat and power stations are often in need of optimizations. A simulation model is a tool for findingways to optimize the plant. The scope of this diploma work is to develop a simulation model ofBoiler 5 at Mälarenergi AB. Boiler 5 is a circulated fluidized bed boiler that was taken into service inyear 2001. Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

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.

Jämförelse av olika reglersystem för undervisningsändamål

Examensarbetet syftar till att jämföra nya alternativ till olika system för användning i laborationer i reglerteknikkurser för olika studentkategorier. Det skall utredas vilket av ett antal alternativ till mjukvaruplattformar som är bäst lämpat att användas vid reglerteknikundervisningen i ITN:s reglerlaboratorium vid Linköpings universitet. Tidigare laborationer i berörda kurser skall även modifieras så att dessa kan genomföras i de nya systemen.Examensarbetet resulterade i en rad modifierade laborationer och system att tillämpa i dessa. De nya systemen medför att all reglering sköts direkt från en dator istället för tidigare variant med externa apparater som programmeras. På så sätt kan större fokus läggas på regleringen i sig och inte de system som tillämpas för att utföra den..

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.
