The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

The crisis on Wall Street. This essay is a comparative study of how two business newspapers report on the bankruptcy of Lehman Brothers Holdings in September 2008. Seven articles from the Swedish European financial newspaper Affärsvärlden (Business World) and five articles from the Chinese-Asian news agency XINHUA FINANCE are examined. The aim is to analyze, understand and evaluate from a rhetorical perspective. My thesis is that rhetors storytelling can tell us more about how we cope with crisis in the global economic discourse. The texts can portray man as a narrative creature when identification as a rational actor is not enough. The analytical methods used are linguistic analysis with an emphasis on metaphor analysis, narrative analysis based on pentad - Critical dramatism, and discourse analysis with doxological outlook. The results show that both newspapers seek to defend the global economic discourse, but they do so in different ways. Affärsvärlden advocates calmness and conveys a cautious attitude. The heart of the crisis, as well as its solution, is on Wall Street. XINHUA advocates control and expresses confidence in authorities and the system. Asia is presented as Wall Street's savior..

In April 2007 we contacted Lennart Augustsson at Designpartners AB in Västerås. He came up with the idea to investigate and evaluate their construction of a interaction beam, CSB-beam. CSB is short for Connector Interaction beam. The beam is based on a horizontal C-profile of high-tensile steel and in the bottom of the profile are vertical flat bar welded so called block connectors. These block anchorsare also made of hightensilesteel.

Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.

A brush of paint on a grey compound wall can mean so much more than simply an addition of colour. It can meanan appropriation of public space, a shared public space enclosed by a wall now ?owned? by someone. It can meanan arisen conflict leading to debate about the right to use public space.The Wall Project is a Mumbai based beautification project that uses paint and outdoor walls to brighten uptheir city. The Urban Typhoon workshop is an activity set up in self-evolving neighbourhoods where municipalinterference is scarce.

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

Masonite Beams AB är ett företag som är väl etablerat i Sverige men har för avsikt att expandera till främst Norge, men även till de andra Nordiska länderna. Masonite Beams behöver därför skapa nya spännviddstabeller för sina I-balkar med hänsyn till de olika nationella bestämmelserna i respektive land. Detta examensarbete behandlar de olika nationella kraven för Sverige, Norge, Danmark och Finland för bostadsbjälklag. Arbetet omfattar en dimensionering i respektive land för ett HI300 bjälklag. Samtliga aktuella länder baserar sin dimensionering på Eurokod med nationella bilagor.De olika nationella valen till Eurokod resulterade i stora skillnader i den maximala spännvidden för ett HI300 bjälklag.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Lumilos is a work investigating the possibilities to use light and color in an interactive design context. I have explored different light sources and compared them to each other and given a short description of the history of light and how it has been developed during the industrialization in the western world. I have also investigated what is currently done in the field and summarized that with examples in the categories passive-, colored-, material- and interactive light. The conclusion is that working with interactive color and light is a hard task. There are many different angles to take into account such as personal likings and earlier experiences that is uncontrollable by the designer. Yet there are many possibilities and light is a material that is moldable in many forms. I have put the knowledge about light and color into practice and developed an interactive light wall that is visualizing energy consumption with the use of different colors of light and animations.

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.

The aim of this report is to give a concise description of curtain walls, what it is and why they are used. It is also a description of six different but commonly used design technologies. By giving a detailed description of the different types and there special properties, the pros and cons will be clarified. The three most interesting alternatives were selected to be included in a test, to show the best alternative from a certain point of view.The parameters are:? Environment? Cost? Ergonomics? Isolation against noise and fire? DurabilityThese are important parameters in the planning and design phase.

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

In this thesis a concept for floor hatches for foam pits has been developed. Since there is an existing solution that is powered by hydraulics and is expensive, the goal was to develop a cheaper solution, as simple as possible.A number of different concepts were developed and evaluated. A concept with five sections that are pulled to the side and stacked on each other was chosen as it was thought to have the lowest risk of crush injuries and to be easiest to manage and control. In the opening behind the foam mattress a lifting table is placed to regulate the height of the stacked sections.To be allowed to be installed in the floor of sports halls the sections must be dimensioned according to the construction standards for these types of buildings. Different dimensions of beams in steel and wood materials were evaluated and of those, who lived up to the requirements of the standard, a concept was chosen.

The purpose of this bachelor degree thesis is to analyze technical issues associated with an implementation of a low sloping trash rack with narrow spacing. A hydropower plant in Umea?lven was used as a case study. The basis for the study was a model where trash racks were dimensioned for inclinations between 25 and 45 degrees. Corresponding head loss, durability and water speed through the rack were then determined for each inclination.
