In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.

This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

The energy that the earth receives from the sun hourly has potential to cover a year?s energy demand in the world. Further, this type of energy is environmentally friendly, natural and free of cost. This report covers solar energy in an urban environment and consists of a case study of installations of photovoltaic cells in a part of the city of Stockholm. It is mainly the economic aspects that are covered but there is also a discussion about the practical consequences and the sustainability as a result of integration of solar energy in an urban environment. The aim of the study is to present results from economic calculations for utilization of solar energy in chosen buildings in Kungsholmen in Stockholm.

The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

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.

This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.

This article seeks to re-imagine the Alandish hembygdsrätt to a regional citizenship. Hembygdsrätt is a judicial tool that regulates acquisition of property and voting rights. Its a central part of the autonomy as it constitutes a social-border between Finns and Alanders.However as Åland and Finland became members of the European Union questions arouse concerning the legitimacy of the current statues. The community argued that it could be considered as a breach of the anti-discrimination principle. Therefore Alandish autonomy was recognized as an exception in the joint-accession treaty of Finland and Åland.

<p>This explorative study examines approximately one hundred electronic library homepages. It focuses on four aspects: form, content, structure and user support. Form relates to the presentation of information and is concerned with the relationship between text and graphics. Content refers to the type of information and services that an electronic library offers. Structure is concerned with the guiding principles that have motivated the grouping of information and services on the homepages.

Karl Andersson och Söner is a well-known family company that has been located in Huskvarna since 1898, and they are producing furniture for private- and the public environment.The aim with this project is that the product should lead to increased sales, as well as expand their collection to appeal a wider audience. The work is permeated by two issues, to achieve as good results as possible. The issues will bring up how to make a table better, in terms of the competitor?s options, and how to apply a design process to develop a table that meets the markets needs and requirements.The design process of the work consists of strategically picked parts from three separate design processes.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

The aim of this master thesis is to show how the dissemination of scientific information took place and developed during the 19th century. The main focus is Lund University. Therefore I have formulated two questions: How did the five heads of the history department at Lund University publish their research findings in the 19th century? What factors in society influenced the scientific spreading of results in the 19th century? To assess the scientific reliability of the sources I have used a method based on source criticism and hermeneutics. The thesis covers important concepts such as the exchange of publications between the universities, commercium litterarium and Akademischer Tauschverein and also the development of Lund University yearbook.

Among farmers in Sweden hedging of product prices is a relatively new way of thinking. A deregulated market and a more volatile price picture are consequences of the free market and the movements towards globalization. The effects of globalization are largely a demand- and supply driven market. These factors give the farmers incentives to stay informed and to act on their own in order to manage their price risk exposure.The overall purpose with this study is to analyze the farmers? attitudes and awareness of price hedging and to examine what type of decision processes that characterize hedging decisions.The study covers the period 2006 until 2008 and the crops oil seeds, barley (malt), milling wheat, feed wheat, oats and feed oats.
