This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.

Fresh Kills park and the The High line park in New York, Downsview park outside Toronto the birch landscape at Shiphol Airport have something more in common than being big new park landscapes.They all include thoughts and images about ecology. These images are neither typically nature picturesque nor typically garden stylish. In Sweden we have the biotopes of Ankarparken, the new design of Kristinebergsparken. At Chelsea Flower Show in England Swedish nature put in a garden format is winning awards. There are some new ecological influence in the air.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers.

The competition for the beach promenade in Helsingborg was announced in 2001 and was arranged by the city of Helsingborg. My contribution to the competition represents the main part of my thesis in the Landscape Architecture Programme. The competition entry is based on the concept of crossing screens of vertical elements which connect the pattern and structure of the city to the beach and the water. The different materials and designs of the screens relate to the various characters of the different parts of the area and they form a sequence and uniting theme along the beach. In addition to the competition entry which was made in 2001, the thesis contains a second part, made in the spring of 2006. It consists of an Introduction with the competition programme and a description of the starting points, a part called Method where the process is described, and the Conclusion with reflections on the competition entry and the process where I also introduce and comment on some other projects which in different ways have are connected to my concept. .

In recent years, the penetration of new players on the telecom market hasdrastically increased the work pace, affecting both design and production. Inthis report the technical and economical potential of a DC/DC converterplatform is investigated, in order to shorten the time of the design process.This is done in comparison with the present discrete type designs. PowerIntegrations offers a product, the DPA-Switch?, enabling this.By developing a wide DC/DC converter platform based on the DPA-Switch?,many advantages are gained. The component count is decreased by up to48 % and the yield increases by up to 2.9 % which in all yields a costreduction by up to 43 % or ?390 000 for 100 000 manufactured units.

The following paper looks into MaternityPaternity leave and how the parents make use of it. The underlying reasons for the paper, is a pattern of unequal division of leave between the mother and father.By using a qualitative in depth interview technique with couples that have children between 2 and 3 years old we have looked for reasons why the decisions, around the division of leave, have been taken, and what factors influence the outcome.We have found that great importance is attached to, how, the negotiations are carried out between the parents, although these negotiations are influenced by a series of circumstances where the families economic situation influenced by the employment market are important factors.The results from the empiric part of the study showed a link between the childs age and which parent stayed home. Furthermore, the results show the families place in relationship to the structure of society also plays an important part in the concluding division of leave..

Arbetet kretsar kring tre huvudkategorier. Hållbarhet, designprocess och kriminalvård. Första delen innehåller informationssökning för att skapa en stabil grund till arbetet. Efterhand övertar ett parallellt arbete med de tre huvudkategorierna som till sist utmynnar i en produktionsfas där tillverkning på Industritextil Job sker för att ta fram en skiljevägg i skala 1:1. Stor vikt läggs vid att sätta sig in i vilka behov som bör lösas på anstalten.

Uppsatsen ämnar svara på en övergripande frågeställning som lyder: På vilket sätt kan genrer fungera som ett stöd vid design av IT-artefakter? Detta är uppdelat i två syften. Det ena är att utreda om ett medvetet arbete med genrer kan stödja designprocessen vid design av IT-artefakter. För att svara på detta görs en genomgång om vad litteraturen säger om genrer och sedan testas detta på ett designfall som genomförs på en handdatorapplikation, närmare bestämt ett mobilt säljstöd. Det andra syftet är att vid förberedande och genomförande av detta designfall samla ihop och sammanställa designråd lämpade för handdatorer.

This study is made in order to see how music teachers pedagogic design their teaching from a semiotic design theoretical perspective. A survey was done in a study to see how the music college students experienced their music theory teaching. This was followed by an observation of two different music theory teachers teaching music theory and with subsequent interviews. One teacher taught music theory at a swedish non-compulsory School of Arts, Kulturskola, and the other music teacher taught at an independent adult education college. The study's questionnaire, observation and interview revealed patterns of teaching, probably largely due to the teaching tradition.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

The aim of this study is to better understand the Swedish concept of ?förebyggande socialt arbete?, preventive social work. I have conducted eleven qualitative interviews with different key persons and skaters, together with participant observation. During the process of analyzing the material I have used Randall Collins´ concepts of interaction ritual chains together with Jean Laves and Etienne Wengers concept of situated learning. The answers could be split up in three areas, first those who regard prevention work as building good things for the future.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.
