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.

AbstractOur bachelor degree thesis was carried out in collaboration with Ivar Petterssons Järnmanufaktur AB in Smålandsstenar. We were asked to replace their wedge housing, used to fasten the wires to the power lines, with a similar structure in a plastic material. The idea for this project started with Ivar Petterssons Järnmanufaktur AB having problems with the casting quality that forced them to perform expensive tests on each of the wedge houses to ensure the quality. They are currently produced in China which is also a major drawback because it requires expensive long delivery times.The method we used is Fredy Olsson's Princip- and Primärkonstuktion (1995). We have consistently been in the project on so-called "broad front", which means that you create several sketches, ideas and changes in parallel, and then evaluates all.

A Queer Reading of Charles Bukowski?s Women and Love is a dog from hellThis thesis aims to examine how the representation of gender is portrayed in relation to sex and power in Charles Bukowski?s novel Women and poetry collection Love is a dog from hell.The theoretical frame of the analysis is based on Judith Butler?s queer theory regarding the heterosexual matrix and gender performativity. The analysis consists of a textual comparison where a specific selection of poems is analysed parallel to the novel to see how they interact and how they oppose each other, through a queer reading.The analysis is divided in three parts where the first one discusses the construction of masculinity in Charles Bukowski?s protagonist Henry Chinaski and how this is presented differently in the two literary genres. The second part reveals how sex is presented in relation to power and how active and passive women are considered as sexually acceptable.

SammanfattningBakgrund och problemdiskussion: År 1995 anslöt sig Sverige till Europeiska unionen (EU), men trots tolv års medlemskap har Sverige fortfarande inte tagit det sista avgörande steget mot Europeiska monetära unionen (EMU). EMU är en vidareutveckling av EU:s inre marknad och ska verka för ett ekonomiskt och monetärt samarbete mellan medlemsländerna. När Sverige gick med i EU innebar det att vi i enlighet med fördraget, har en förpliktelse att ansluta oss till EMU när vi uppfyller unionens uppsatta kriterier. Eftersom Sverige står utanför EMU och företagen handlar med länder i området, uppstår valutarisker för företagen. Vi undrade därför hur de ser på en anslutning till EMU och hur de säkrar sig mot valutariskerna på grund av utanförskapet.Syfte: Syftet med uppsatsen är att undersöka hur svenska företag ser på Sveriges utanförskap i EMU samt hur de med hjälp av olika instrument och tillvägagångssätt hanterar problematiken med valutarisker.Metod: Vi använder oss av en kvalitativ metod, där vi intervjuat fem företag med betydande andel export/import till EMU-området.

Natt i marknadstältet is considered as one of Lars Ahlin?s most significant works of fiction. The novel is complex in structure and meaning, containing numerous stories and characters entangled with the main story. One of these stories is the subject of this essay:?Berättelsen om Hedvig och hennes son?.

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.

Pharmadule Emtunga is using a modular building concept for building pharmaceutical factories. The modules contain these pipes. The goal of the thesis was to present concepts for technical solutions regarding welding methods and fixtures for the cell. Conceptual models for the cell were made with aid of CAD software.

The main purpose of this thesis is to investigate the possibility to communicate messagesrelated to sustainable development through cultural works. Culture is here synonymous toliterature or, more specifically, the fiction genre. According to ecocritical research, this genrehas the capacity to contribute to a more sustainable development and is therefore interestingto analyse from an environmental point of view.The novel selected for the study is Vips så blev det liv - eller en hyllning till blågrönalgen(2010), written by the Swedish author Bob Hansson. The analysis is mainly focused on howthe book?s climate related messages are formulated and integrated in the story.

Sweden has formulated ambitious energy goals which signify that by year 2050 the energy usage should be halved. One of the objectives is the reduction of energy usage by 20% by year 2020 and that it should be compared to the usage of energy from 1995. In parallel with increased energy requirements for buildings the demand on housing conservation, by highlighting also buildings from the last 50 years as part of the building heritage, continues to enhance, which in theory means that there is a conflict between these.The law will never be able to point out unique buildings and PBL (planning and building act) is not especially concrete. The National Housing Board has tried to make this more concrete by the new BBR regulations though there are still an enormous variety of interpretations.This report deals with the conflict between conservation requirements and additional insulation of the building envelope and is limited to multi-residential buildings built between the years 1945 and 1975. It is the stock with the greatest energy consumption and that is where the big challenge lies.

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.
