In many products a compromise between ground clearance and the required space to store the product has to be made. This problem attracted the attention of the authors of this thesis.The objective of this project is to develop a functioning solution to a foldable wheel. The solution should be applicable to several types of product groups. A limitation for this work has been made so that the work only covers solutions for lighter vehicles.The purpose is to drive this project forward, so that a solution can be found. Furthermore the purpose of the report is to clarify how the authors proceeded to design and construct the wheel according to a fixed specification.

The purpose of this Master Thesis has been to investigate the possibilities for a new type of noise reduction solution that could decrease the negative effects resulting from larger traffic roads. The idea has been to construct a noise barrier with a roof ? like a tunnel placed on a road. The choice of material has been focused on transparent materials in order to lower visual intrusion and barrier effects. This project idea is called the Noise tunnel.After having investigated the current offer of noise solutions, it has been concluded that these solutions rarely provide a sufficient level of noise reduction ? at least not when government regulations of acceptable noise levels are applied.

The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing. I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.

The purpose of this master thesis has been to find different solutions to the design of a headlamp with a cluster of three or possibly four high power LEDs (Light Emitting Diodes). During the work, two different problems have been considered; how to design a lens in order to shape the light beam in a desirable way, and how to design a cooling system which will lower the temperature of the LEDs as efficiently as possible, still taking into account the geometry set by the optical solution as well as other given geometries. The results presented in this thesis are partly the outcome of a literature study, but derive mainly from a number of tests and measurements made on two test rigs and one concept prototype..

This essay revolves around the reformation and sectorization of Swedish psychiatry starting in the 1970?s. Psychiatry was to change from being based in closed asylums to being an institution in the middle of society, finding social solutions to mental illness and working through a dynamic network of various care givers, such as welfare officers, nurses and psychiatrists. This new kind of psychiatry was first tested in Nacka, where psychiatric reformers Johan Cullberg and Bengt Berggren were the heads of a six-year long pioneer project of sectorized psychiatric care. My specific purpose is to analyze the new ideas of mental illness and of psychiatry?s role in society which were introduced in this project and how they were expressed in the official reports presenting it.The reformation was preceded by a public debate concerning psychiatry, which had intensified a few years around 1970.

This thesis work has been performed on request by SWT (Scandinavia WeldTech AB). SWT manufactures, develop and sell ready to assemble building systems for concrete rafter beam applications. The beams in this system consist of a u-beam that is welded to a flange. To be able to fill the beams with concrete there is holes in the beams top end. The holes are made in a ?punching machine?.  These holes are cut out and the remaining steel piece is bent down in the u-beam.

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

I rapporten undersöks säkerhetsaspekter för företagsapplikationer utvecklade till androidplattformen. Rapporten tar även upp Androids grunder och dess säkerhetsmodell. Syftet med rapporten var att undersöka Androids lämplighet för projekt som HOW Solutions har planerade. Under arbetet har en applikation för trådlös öppning av lås utvecklats. Resultatet var att många av de hot som upptäcktes var, för företag, i vissa fall är svåra att mitigera och att viss relevant funktionalitet saknas på plattformen.

AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..

This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

Purpose: Corporations today see a greater responsibility towards society regarding the environmental impact of their actions, using available transportation options that are more eco-friendly can reduce this impact significantly. Martinsen and Björklund (2012) identifies a set of gaps between supply and demand of green logistics services. This paper aims to address what it is that affects the demand for these alternative solutions and what could be done to increase the usage of them, thereby decreasing this gap.Design/methodology/approach: A quantitative study with six Logistics Service Providers (LSP) and 24 companies that purchase transportation services, all operating in Sweden. Data is collected through semi-structured telephone interviews with people responsible for the purchasing of transports as well as key account managers within the service providing companies.Findings: Just as the LSP?s interviewed in this paper thought, the main focus of the transport buying companies are the costs.

In this essay, I investigate the representations of poverty in two charity galas on Swedish television. Moreover, through a discourse analysis, I look at how the concepts of ?development? and ?poverty? are used in these galas. I have watched two galas from 2012; Tillsammans för världens barn and Humorgalan. The shows turned out to be quite different from each other, as one of them was problematizing the concept of ?poverty? more than the other.

Problemet med dagens standard för hygienrum och dess komponenter är att de baseras helt på tillgänglighet. Vilket i och för sig är en bra sak, sett utifrån att fler personer kan ha möjligheten att utnyttja bostadsfunktionerna även om de har vissa rörelsehinder. Men vi vill ta steget längre, inte endast se till tillgänglighet utan även se till vad som kan uppskattas, för att höja levnadsstandarden och uppskattningen av våra hem. Den svenska standarden är som tidigare nämnt baserad på tillgänglighet och är inte alltid anpassningsbar till nya lösningar och komponenter som kan förekomma i badrum, vissa saker ändras, får nya funktioner, kanske utökade användningsområden. Syftet är att försöka utöka möjligheten att nå högre kvalité för badrummet och samtidigt försöka se till de alternativa lösningarna som kan åstadkommas idag.

The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.

Denna rapport behandlar ett examensarbete med målet att hitta en paketering för resursövervakning i nätverk (NPMD - Network Performance Monitoring & Diagnostics) samt centraliserad logghantering (SIEM - Security Information & Event Management).Arbetet har utförts över fem veckor och bestod av att undersöka vilka produkter som kan vara möjliga att leverera till Ateas kunder genom att ta fram förslag på produkter och sedan utvärdera dessa i en virtuell testmiljö.Efter att två veckor av arbetet passerat beslutades att enbart SIEM-produkter skall utvärderas då vi annars inte kunnat hålla tidsramen på fem veckor. De första två veckorna bestod mestadels av efterforskning av olika produkter baserat på ett antal kriterier.Applikationen ska:? Stödja mallar och regler för Payment Card Industry Data Security Standard (PCI-DSS)? Stödja korrelering av händelser? Ej vara open source eller en hårdvarulösningUnder resterande tre veckor installerades, konfigurerades och utvärderades de produkter som var intressanta för ändamålet. Utvärderingen av produkternas funktioner och egenskaper utfördes i en virtuella miljö. Resultatet av testerna är ett dokument som innehåller information om varje produkts förmågor samt betyg på varje produkt.
