Bärförmågetillväxt i pålad friktionsjord

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

Utvärdering av laddningskoncept för lastbilsbatterier

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry

The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.

På vandring mot handling : Utbyte av perspektiv i landskapet

Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.

Utveckling av takra?cken fo?r sla?pvagnar

This report is a bachelor thesis work in the field of product development and design. The assignment has been to develop a solution for roof racks, normally used for cars, to fit on the open trailer models FS1425 and Alugance. The project was implemented by Johan Andersson and Victor Karlsson, students at the Mechanical Engineering program with a focus on product development and design at Jo?nko?ping?s school of Engineering, in spring 2012.The client wants to use transport solutions in the same way as roof racks on cars. The user of such a product is assumed to desire simplicity, safety and an attractive design with an appealing price, which has been a challenge during the thesis work.Pre-studies have been conducted to examine the potential competitors and gain knowledge in the research area.

Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use. Weather may also be an important factor. In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.

"Yes! Man kan bli kranförare." : - En studie av manligt tolkningsföreträde i svensk inrikesnyhetsjournalistik

The free press is an invaluable part of the democratic society and a pillar stone in the creation of ideas, opinions and norms. According to theories such as agenda-setting and framing the media have a significant influence on people?s perspectives and opinions. With this view of media along with the gender system provided by Yvonne Hirdman as a framework, this study intends to examine the gender representation in Swedish domestic news journalism. The study consists of a quantitative analysis of two major Swedish morning papers, Dagens Nyheter and Svenska Dagbladet, where the gender representation regarding journalists, main news sources and pictures are being accounted for.

Beräkning av ASME-flänsar enligt EN-standard

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Hållbar Utveckling 2010 : Hur uppfattar lärare begreppet idag?

This work is a study of subject teachers in social studies and science understand the concept of sustainable development. The work uses a qualitative and a quantitative approach. Teachers in various schools and stages have been answering questions about how they perceive sustainability, how they implement it in teaching and if they feel that school is important for the future of sustainable development at large.The theoretical background is based on environmental ethics as well as the different meanings and definitions of the concept of sustainable development. These theories and definitions are coupled with the empirical results.The study concludes that all teachers throughout the study perceive the concept of sustainable development as something ecological, something that has to do with nature. A few teachers also state economic and social dimensions.Questions about how the teachers in the study implement the concept in their teaching can be seen as three different approaches.
