Konstruktion av specialmaskin för orientering och positionering av nyckelämnen

The thesis in product development ? mechanical design includes 15 credits and was carried out during the spring of 2014 at Semcon in Eskilstuna. The task is to construct a special machine for positioning and orientation of a key blank found in six different shapes, the construction is a part of a larger machine for encoding the key blank where a pick- and-place device or robot pick up the key blank and deliver it further in the process. The entire construction is designed for ASSA OEM Gothenburg.In order to accomplish the project the first step was to analyze the existing solutions to similar problems on the market in a current situation analysis to create an understanding of the problem. This was followed by a flow analysis and a functional analysis to get a deeper understanding of the problem and structuring the machine's process flow and its features.

Förbättrad vakuumtätning mot kabeln under plastextruderingsprocessen

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.

The role and influence of the Architect in industrialized building

An emerging trend within the construction industry is the expectation of the customer to experience and sense the product, maybe even in a customized manner. The latter trend would extend the necessity of incorporating not only function and aesthetics, but also perception and sensation. To meet this trend while at the same time improve the productivity the use of information technology such as BIM and technical platforms has increased in construction projects. Nevertheless, in spite of large investments, the construction industry has not managed to increase the effectiveness and productivity as much as other industries. Evident is that successful use of information technology depend on the integration and collaboration of various experts in a continuous and dynamic process.

Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

Samband mellan utbildningnivå och grad av konformitet till traditionella maskulina normer

AbstractTitle: Correlation between the levels of education and conformity to traditional masculine normsAuthors: Larsson, M., & Ljungqvist, D. (2008)Objective: This study is an attempt to explain correlations between the levels of education and conformity to traditional masculine norms. It is mainly based on the social construction of gender. Background: A high level of education is associated with a healthy living, and a high conformity to traditional masculine norms associated with harmful health behaviours. The background also presents different views of masculinity, the construction of gender and the construction of norms.

Förändringsledning vid LKAB: Implementering av 5S, ett verktyg inom ledningsfilosofin Lean

I dagens företagsklimat har kraven på produktionskapacitet i tillverkande företag blivit allt högre. Förändringar i och utanför produktionen blivit mer dynamiska och komplexa och företagen måste säkerställa ständig och hållbar utveckling av produktionen. Idag är ett vanligt förändringsinitiativ Lean, vilket är ett begrepp som innehåller både filosofi och principer samt kvalitativa och statistiska verktyg. Men ett stort antal av förändringsinitiativen misslyckas och företag som tidigare vunnit pris för operationell excellens klarar i många fall inte av att upprätthålla utvecklingen. För att lyckas med förändringar verkar det alltså krävas något mer ? inte bara ett systematiskt ledningskoncept, som till exempel Lean.De senaste åren har LKAB satsat på ett antal förändringsinitiativ som syftar till att skapa en mer medveten kultur för att nå de uppsatta målen enligt den framtagna strategin.

3D-visualisering i markprojekteringsprocessen

The thesis has been made for NCC Teknik in Gothenburg. The NCC Corporation is one of the largest leading companies in Scandinavia within the construction industry. NCC is active throughout the whole construction process, where one part is to carry out soil investigations prior the construction of various buildings, for example residential buildings. NCC Technology wants to visualize the samples taken at the construction sites in 3D for clients, authorities and also internally to show in a simple and understandable way how contamination is spread out in the soil.The thesis includes the area of Limhamns läge in Malmö, previously an industrial area. The area has previously included a concrete factory and the contamination from that factory has lingered in the soil.

Trapphus i träplattform för CBBT

Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.
