Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

This report describes the development of a RESTful web service for mobile applications. The web service makes resources from an existing system called kompetensdatabasen ("the competence database") available. Kompetensdatabasen holds information about the capabilities of consultants and about assignments carried out at the IT consultant business Nethouse AB.The web service was developed according to the principles of REST and ROA (Resource Oriented Architecture) which puts focus on making resources available. The resources are made available through the HTTP protocol and the methods associated with it. This means it was designed to use the same technologies as the world wide web.

The present study deals with task-oriented conversations between a person with hearing loss and a relative or friend. The purpose was to investigate how the participants in the task-oriented context co-construct understanding, and to focus on different kind of repair strategies that the participants may use to make the hearing loss relevant in the conversation. The method used was Conversation Analysis (CA). The material consisted of eight videotaped task-oriented conversations between a person with hearing loss and their significant other. Altogether eight persons participated in the study ? four of them had a hearing loss and the other four had normal hearing.

The purpose of the study was to examine how teachers and children interpreted the project and understood its values. To this end, it was necessary to focus on four defining parameters which affect the investigation: structure of pre-school project work, content and delivery, the methods used by teachers during the project, which pedagogical documentation was used (and how), and how the project determined the approach, the curriculum goals and values. Using a qualitative approach, regular unsystematic observations were made over five days, during which three teachers, two pedagogues, two pre-school teachers, and one nanny from the same kindergarten were interviewed regarding children in three age groups: 1-2 years old, 3 years old, and 4-5 years old. The results of my investigation showed that the teachers were divided on how to apply the project as a working method. Children's active role in the pre-school project varied depending on the extent to which teachers adopted children perspective in everyday practice.

At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

A project exploring the boundaries between 2D and 3D. What is surface and what is substance? A countinuation of previous projects where I?ve examined the journey from two dimensional paper to three dimensonal objects. This project deals with the journey from three dimensonality back into a flat two dimensional surface, and the question if something can be both 2D and 3D at the same time. I decided not to center the project around a specific item, but rather let the project itself be in focus.

This thesis has been written at Linköping University for the company Instrument Control Sweden AB (ICS).ICS is a small company located in Linköping that develops software and hardware for Unmanned Aerial Vehicles, UAV. At present, ICS has a fully functional autopilot called EasyPilot but they want to reduce the autopilot?s size to make it more attractive.The purpose of this thesis was to investigate if it was possible to reduce the size of the autopilot and how, in that case, it would be done. It was also necessary to examine whether the old processors should be replaced by new ones and how hard it would be to convert the old software to these new processors.To succeed with the goals many of the old components had to be changed for new, smaller ones. Some less necessary parts were also completely removed.

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.
