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.

The aim of this paper has been to examine personas role in the development phase and whether or not some of the criticism that have aroused against personas is valid or not. In this paper we examine the benefits as well as the downsides of working with personas both from a scientific point of view but also from the experiences of a small company located in the north of Sweden. Since personas much like many other powerful tools have pit falls aswell as do's and don'ts this paper looks to clarify what role personas should take aswell as how to minimize risk and maximize the usefulness of personas..

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

SammanfattningLångvarig smärta orsakar stort lidande för individen och belastar samhället ekonomiskt. Syftet med denna uppsats var att undersöka om en exponering in vivo-behandling inspirerad av Dialektisk beteendeterapi (DBT) för människor med långvarig ländryggssmärta var görbar samt om behandlingen gav effekt på smärtrelaterad problematik. Designen var en single case experimental design vilket är en beprövad design för att testa nya terapimetoder. Studien bestod av sex deltagare, alla med hög grad av smärtrelaterade katastroftankar, något som litteraturen visat predicera sämre behandlingsutfall. Behandlingen var DBT-inspirerad och indelad i tre faser; en första valideringsfas, en andra färdighetsfas och en tredje exponeringsfas.

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

To find competencies on a workplace with flex office structure.Companies today, 2012 are facing new opportunities and challenges. Information technology develops, competition is bigger today than ever, increased environmental requirements will be added and new patterns of life and values are occurring. This means that people who work in offices feel strong pressure of conversion, which is something that people experience differently. Therefore it is essential how the working environment is designed in an office. Working in an office means a lot of information processing and we can see large changes taking place.

The purpose of our study is to determine whether a membership in FRII exercise any influence over the fundraising organizations accounting and work, and if that?s the case we want to study the effects.We began with a search for information about the theories we intended to use in our study and to establish hypotheses. We came to the conclusion that the agency theory and the stakeholder model were the most relevant theories for our work. We also chose to discuss problems in accounting, legitimacy theory and standard setting.We decided to conduct a total opinon poll due to the fact that FRII only have approximately seventy members. We also decided to conduct a cross section approach which means that the attempt of our study is broad but rather shallow.

During pre-slaughter handling of pigs the animals are often subjected to methods that induces stress and are a threat to the wellbeing of the animals, such as mixing of groups, loud noise and transportation. A new law will be implemented in 2006 in Sweden that prohibits mechanical noise exceeding 65 dB in abattoirs. The purpose of the research presented in this paper was to examine the effects of noise and transportation on pig behaviour. The activity and aggressiveness of the pigs were examined with behavioural studies during transportation and during three different noise levels: 55, 75 and 95 dB. Before the noise treatments took place the groups were mixed and half of them were transported for approximately 2 hours. In the study 432 pigs were used.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

This study is based on narratives from two victims of violence. A raped old woman has turned to be the core of this narrative of narrative. She is both a narrator and the head person in her narrative. Her narrative turned out to be a dialogue between two genres namely her trauma story and her life story. By experience violence has been associated with masculinity and powr, which is discussed in some detail.

This is a final project which makes up 20 credits at the Landscapearchitecture programme at SLU in Alnarp. The thesis is design based. My final project is comprised two parts; of a competition entry for ? A New Square in the Centre of Täby? as well as a theoretical study that derives from the competition proposal. The competiton itself was announced on March 1st 2007 with the final hand-in date on May 28th 2007. The program of the competition asked for a flexible urban square that offers a diverse range of activities that can be used during both night and day, all year around. I became interested in the term ?mutlifunctionality? and I went on to use the subject as a base for my design approach.

This bachelor?s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.

This thesis describes the redesign ofequipment designed for drying bags thatis used in Fresenius Kabis´manufacturing of their nutritionmedicine in Uppsala. The need of thistask arise during the start of thedevelopment of a new packaging line werethis equipment were meant to be used. Anevaluation of the bagdryers capacity andcapability was necessary.The work started with gathering ofinformation from suppliers of the usedcomponents and from the responsibleengineers for this equipment. Aneducation to learn how the equipmentworked and how to operate it were taken.That was followed by the creation of astudy plan were the tests were plannedto test different parameters effect onthe drying result and to see if thebagdryer managed to handle the bags ofthe correct format in the pace that theequipment should be designed for.The test results detected a need ofdesigning a unit with a function thatholds the bags in place while passingthrough the dryer in order to attainhigh quality results. The results werelater used for optimization of thedesign.

Technological developments have affected many different areas. Something that has undergone major changes in this respect is gambling. Because of technology, the accessibility to games has never been greater. Using smartphones, tablets and online casinos makes it possible to play virtually any time of day no matter where you are. This development has caused that more people, got stuck in a gambling addiction which have become an increasing problem in the last decade.
