Analys och dimensionering av robusta kilspårsförband
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.

Karaktärisering av höstvetets avkastningskomponenter
Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.
Revisionspliktens avskaffade -Vilka effekter kan förväntas och vilka eventuella förändringar sker hos revisionsbyråerna
This essay examines the expected impact of the statury audit exemption in Sweden from anauditor perspective and any conscious changes made on the accounting firms to meet the abolition.The theoretical framework is divided into three parts where the first deals with the concept of audit, who the stakeholders are to revised information, the auditor's function from an agent and positive accountingtheoretical perspective and the expectation gap of what an auditor cando and what the client expect audit to be. The second part deals with the audit exemptions and effects in Denmark and England. The last section addresses the current debate, studies and statements by FAR SRS, small businesses, banks and the tax authority.The essay is essentially inductive with a phenomenological operator perspective. The thesis has a qualitative approach with four respondents who are authorized or approved as an auditor with extensive experience, active on four different accounting firms. The questionnaire is divided into two parts where the first part consists of a number of very open questions and the other part of more structured questions in order to obtain comprehensive answers.The survey shows that a number of new services, certifications and authentication degrees are to be expected in Sweden aswell.
Det energisnåla isoleringsmaterialet
This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.
Förrotation till omrörare
The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.
Utredning om huruvida Dalarnas Tidningars produktion passar en KBA Cortina
This degree project illustrates newsprint and waterless offset. A new news press was introduced at Drupa-00, Cortina from KBA, which is the first news press dedicated the waterless technique. With actual statistics from the company in question an investigation was made whether their production fits this press. It came out in the investigation that the production of the company, from statistics, fits this press very good. A table was made where different timeschedules were accounted for the new press, with semi- and full automatic plate changing for present and to be added papers.
Provning av parallellkopplade hydraulpumpar i hjullastare
Volvo Construction Equipment is a world leading company in construction machinery. Tomaintain the best products, development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the pressure ripple is reduced when the paralleled hydraulicpumps are phase shifted and reduces each others pump pulsations.
Compost and its effects on soilborne plant pathogens
Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.
Limträstomme till hallbyggnader : Utformning och dimensionering av momentstyva ramhörn och 3D-modell framtagning
Industrial buildings are increasing all over Sweden. Farmers are building new modern facilities and the government chooses to build new halls to invest i youth sports. Glulam is the most common framework but there are limitations because of the transport. Therefore, there is a need to develop new solutions to increase the use of glulam.The maximum torque in the eaves was found in the frame with a roof pitch of 18 degrees and a wingspan of 25 meters. Using hand calculations according to Eurocode and comparison with the computer software StatCon, the maximum torque, shear force and utilization rate is calculated.
Bibliotek + skola = sant? : Föreställningar och föreskrifter om samarbete mellan folkbibliotek, skolbibliotek och skola samt om barns läsning
AbstractIn this master´s thesis I primarily investigate librarians´ and teachers´ conceptions of collaboration between libraries and schools and their conceptions of childrens´reading. Secondary I investigate the contents of laws concerning libraries and schools and also the school curriculums concerning the subject field of the Swedish language. My theoretical point of departure is that of social constructionism. I use two models in my analysis. One is a model of collaboration created by Patricia Montiel-Overall, called TLC (Teacher Librarian Collaboration), which grades collaboration from the lowest level (A) to the highest (D).
Europeiska Unionens makt att förändra världen : En kvalitativ studie ur ett normativt perspektiv
The purpose with this essay was to examine how the European Union is working totransfer norms to states they signed an agreement with and provide support for inframe of the Barcelona process and the Tacis programme. The theory which weused was Ian Manners (PhD in Political Science) theory of "the EU as a uniquenormative power". The aim was to examine whether the EU - which Manners mean- has had a normative power to influence states to change. We used a qualitativeapproach through the use of a multiple case study and qualitative text and contentanalysis. The States which formed the basis of our study were within the BarcelonaProcess; Morocco and Tunisia as well as Azerbaijan and Armenia funded by theTacis programme.

Femtio Nyanser av Co-branding - En kvantitativ studie om effekterna av co-branding på konsumenters varumärkes- och produktutvärdering beroende av kvalitetssegment och hedoniska shoppingmotivationer
The retailing industry has an extremely high density of brands. In order to differentiate its offer, both retailers and suppliers, are constantly forced to come up with new ways to launch their products. A collaborative strategy between two brands is called co-branding, which means that both the private label and the supplier's brand are displayed on the new product packaging. Several studies have shown that a co-branding strategy is successful, but many operators are still reluctant to use co-branding in fear of long-term losses due to potentially damaged business relations. The objective of this study is to explain how the product- and brand related value for customers, retailers and suppliers is affected by co-branding between private labels and national brands.
