Analys och utveckling av boggi till ramstyrd dumper

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

En flashestimator för den privata konsumtionen i Sverige med hjälpvariablerna HIP och detaljhandeln ? En tidsserieanalys med hjälp av statistikprogrammet TRAMO

In this essay we aim at finding an appropriate flash estimator of the quarterly Swedish private consumption (PK). With the aid of the statistics program TRAMO we study if monthly data from the consumer survey (HIP) and retail industry (DH) can be used in a transfer function model (TFM) to forecast PK. In the work of assessing the state of the market and the business trend, fast information from the national accounts is needed for making decisions for the economic politics in Sweden. A way to speed up the information process is to use leading economic indicators to asses this development. Another way to get information faster is to use a flash estimate.

Utvärdering och uppdatering av typkurvor

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

Utvärdering av ett silotorksystem för spannmål utrustat med omrörare :

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Småskalig vattenkraft vid Olofsfors bruksmuseum : Med faunapassage

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Implementation av ett digitalt vågfilter på en SIC-struktur

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

Skönlitteraturens nya kläder? Elektronisk publicering av skönlitteratur: en kvalitativ intervjustudie med nio svenska förlag och fyra andra aktörer på det litterära fältet

The main objective of this essay is to present the views of nine Swedish publishers and four other agents in the literary field regarding the possibilities of and obstacles to publishing fiction in an electronic format. Furthermore, whether or not electronic publishing is today actually a viable alternative. A substantial part of the essay functions as background to our interview findings and is based primarily on material originating from the Sociology of Literature field. The introductory chapter expounds the methodological and theoretical basis of the essay and is followed by a chapter placing our study in a larger, international media, context. Chapter three deals with the past decades? restructuring of the publishing sector, the professional functions involved in traditional publishing and Pierre Bourdieu?s theories on the cultural and economic forces at work in the literary field.

Uppvärmningssystem : Ekonomi, miljö och drift

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

Vertikala Trädgårdar : ett grönt verktyg i planeringen av framtida urbana miljöer

In present time, more and more people move into cities. Densification of cities as planning policy together with an intensive urbanization, makes urban planners face with the contradictory task of creating a city that is both dense and green. Façade vegetation has been used for centuries, mainly in the form of various climbing plants that with or without supportive structures have spread over facades to give a green impression to the environment. The development of new technology today allows urban planners to use greenery integrated with façades. Vertical gardens offer a larger variety of plants, and at the same time takes advantage of the technological benefits of vegetation in city planning.

Projektering av en etanolfermenteringsanläggning i pilotskala med Biostilteknologi

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

När tågen slutat gå : förvandling av övergiven räls till publikt promenad- och parkstråk

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

?Man kan säga att det var en bra grej till slut? ? En kvalitativ studie om ungdomars upplevelser i ungdomsprojekt Green Team

Antalet arbetslösa ungdomar är stort i dagens samhälle. Det finns många åtgärder som bedrivs av landets kommuner som riktar sig till unga arbetslösa socialbidragstagare, men det finns för lite kunskap om dessas innehåll och resultat, samt om hur deltagandet i dessa åtgärder upplevs av ungdomarna själva.Syftet med denna studie är att få en ökad förståelse för vilka komponenter som deltagare iungdomsprojekt anser vara viktiga och varför. Vi vände oss till deltagare i projektet Green Team,som riktades mot långtidsarbetslösa ungdomar mellan 21 ? 25 år och som finansierades avstadsdelen Angered. Projektets syfte var att höja ungdomarnas sociala kompetens för att underlätta deras etablering på arbetsmarknaden.
