This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.

AbstractThe purpose of this investigation is to find out how the pupils can discover and to feel joy in their creative art activity and also to believe in their own ability. The aim is to figure out if creative art activity is able to raise the pupil?s self-image. By literature, pedagogue interviews, and interviews with pupils at the age of ten years old and by action research is the way that I have searched for an answer for my question. The main result is that fantasy, creativity, courage and lust are important parts to develop in the job of raising the self-image.

DD är en verksamhet som erbjuder plats för hemlösa personer som har en omfattande problematik bakom sig, där många har blivit utslussade från härbärge till härbärge, boende till boende.

Har ni någon bra kärleksroman? : en studie av indexering av skönlitteratur vid stadsbiblioteken i Malmö och Mölndal. Have you got a good love story? : a study of fiction indexing at the public libraries of Malmö and Mölndal.The thesis analyses interviews with users of two Swedish public libraries to find aspectsof fiction important to users and consequently to be considered when indexing fiction.Descriptions of a novel by 50 users at each library are compared to the index terms usedfor these novels. For the analysis, the authors propose a model of their own based onAnnelise Mark Pejtesen's AMP system for fiction indexing.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..

AbstractThe aim of this study was to investigate the reason why students contact adults if they are involved in any kind of bullying, what support they had received and wished for, as well as to investigate why student don?t contact adults. About of 150 students, 50 girls and 56 boys (70%) had experienced bullying of different kinds; some had more than one kind of experience. The students expressed that they had contacted adults when they ?felt unwell? and to ?stop bullying?.

Our society has become more and more digitalized and we have access to more information than ever before, which has had an effect on both our personal and professional lives. This change has naturally also changed the way in which organizations are structured and how they communicate ? both internally and externally. Intranets, e-mail and other technical channels are an important part of most organizations in-house communication today.The aim of this study is to examine how the internal communication in a medium-sized firm, CranabSlagkraft in the north of Sweden, works. The focus in the study is on the existing intranet, and if there are any differences in the opinions between the firms leaders and the employees that works in the production.

We chose to base our literature study on the meme phenomena. The meme is a portion of culture that is spread among us from mind to mind. Every time we learn something by copying others we use information that has been passed on from a previous person, that information can be seen as a meme. The theoretical frame for our methodology in our exam paper is founded on Forsberg och Wengström research on literature studies. Our aim is to describe to the reader in depth what a meme is and how they could be helpful in an academic and pedagogical setting. Our study will show how memes are seen predominantly as graphic designs and as artifacts for cultural representation parallel to their imagery.

The purpose of this thesis is to explore the experiences and views some users have of the library environment and services of the University Library of Halmstad. The main question to be answered in this thesis is what importance the users attribute to the library environment and services while pursuing their most recent library errand. To answer this question a study of relevant literature on the subjects of library environment, library services and user-surveys in other academic libraries was carried out and a questionnaire was distributed to 22 respondents in the process of visiting the University of Halmstad Library. The literature background and the results of the conducted study were interpreted and discussed and led to the following conclusions: 3 respondents encounters with the library environment and its services were negative in part and thus their experiences and views were relevant to the completion of their library errands. The other respondents? encounters confirmed their overall positive earlier experiences and views of the library environment and its services, but had no real concrete significance for the completion of their library errands..

Syftet med uppsatsen var att beskriva och undersöka om system byggda på TETRA standard kan förbättra kommunikationssituationen för public safety myndigheterna på en operationell nivå. För att uppfylla syftet genomfördes en fallstudie. Vi genomförde fyra intervjuer på brandstationer i Finland samt tog del av en rapport från en pilotstudie i Norge. Alla har gemensamt att de har gått från ett analogt radiosystem till den digitala standarden TETRA. Den empiriska undersökningen visade att stora förbättringar därigenom kommit till på områdena täckning, samverkan, samband och säkerhet, samt att nya möjligheter växt fram vilka inte funnits med tidigare analoga system.

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.

This report is about the shear force design of reinforced concrete according to Europe?s common dimension rules, Eurocode. The purpose is to describe the calculation procedure and the background to the formulas and expressions that occurs. Furthermore results from different calculation methods (hand calculations and computer calculations) will be compared to see how they differ.The goal with this is to go through the parts of Eurocode dealing with shear force and that this will lead to a clear review of these. You should also be able to see how results and the calculation procedure differ between different calculation methods.
