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.
att synas på internet - ett praktiskt företagsperspektiv
Today Internet is clogged up and packed with homepages and information from both private persons and commercial companies. This has led to a decreased availability for a company to be noticed. The most common tool for consumers to use while searching for products online is via search engines. But because of the nature of these, not all companies can have good placements. Our research question was, "How do small online-companies attract consumers to their website"? The purpose of this thesis is to identify how a company works through online-communications and how to attract consumers to their home page.

Jämkning vid bodelning - en möjlighet för båda parter? : En analys av 12 kap 1 § äktenskapsbalken
AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

Kartläggning av materialflödet i Peabs försörjningskedja till byggarbetsplats med SCOR
The construction industry has not undergone the same logistical development as the manufacturing industry; this, in combination with increased material price, leads to the fact that the construction industry must be improved. This master thesis is a part of the research cooperation Brains & Bricks goal of reducing production costs for the construction sector by 25 percent. Brains & Bricks is a cooperation between Linköping University, Peab and Katrineholms municipality. The master thesis aims to identify improvements in the flow of material, the Supply chain operation reference, SCOR, model has been used and the work has been carried out on one of Peab?s construction sites. At present the business is characterized by bad communication both between the construction site and the office as well as between the construction site and suppliers.

The Toyota Production System (TPS) : ett verktyg för att skapa effektiv och lönsam produktion
Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible.
A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability.
Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.

Förväntningar på läs- och skrivinlärningen : utifrån de yngsta barnens perspektiv
My essay is about the latter period of Anne Charlotte Leffler?s authorship. In Part I of my essay, I describe her path from the 1880s, where she described femininity as a shortcoming, as writes Ingeborg Nordin-Hennel, towards the 1890s and towards describing femininity as a possibility. This development took place on two levels ? on an outer level, where all the woman writers in the late 1880s were influenced and where they were pushed out by the male writers, and on an inner level with Leffler herself.Her late literary works depict new and more independent types of women, and eroticism is given a more prominent position.

Vårvetesorters effektivitet i användningen av kväve under den huvudsakliga tillväxtperioden
Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.
