Rätt gåva för rätt tillfälle
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Kommunikation av risk- och sårbarhetsanalys från länsstyrelse till kommun
This master thesis investigates how the county administrative boards communicate the regional risk and vulnerability analyses to municipalities in Sweden. Information has been gathered through a survey and through a case study involving three county administrative boards. The results revealed that there are possibilities to improve or develop the communication in all the county administrative boards. The information channels are often written or web based, these channels promote one way communication rather than a dialog. The thesis gives suggestion on how to work out a strategy for a more effective communication, the case study also gives ideas on how a county administrative board can work with communication..
"Fallbacks" - betydelsen av vandringstid för Atlantlax (Salmo salar L.) som faller nedströms vandringshinder
In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.

Informationssystem för service av truckar och städmaskiner
This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.
Utvecklingen från traditionell ekonomistyrning till verksamhetsstyrning : En studie inom ekonomistyrning
This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara
The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.
Vindfällning i naturliga och skapade bryn och kanter :
The aim of this work was to study if the edge of the forest is more resistant to heavy winds than the trees located further in from the edge, and how this edge effect changes between different types of tree species and site types.
The data was collected from an electric power line going from the north to the south of
Sweden. The mean value of the clearcutted area around the power line was 120 meters. The
main direction of the storm in January 2005 was west-southwest and thus the power line was a perfect place for gathering a large data set.
The main parameter studied was the damage frequency at the edge of the forest compared to
the trees located further in from the edge (up to 100 m from the power line). Tree species mixture, soil moisture class, soil type, topography, stand height, stand height of the stand on the other side of the power line and wind exposition was estimated.
The results showed a distinct edge effect. The edge of the forest had clearly lower damage frequency for all tree species.
A marked difference was observed between tree species and damage frequency.
Svävare : Utforming av hytt
The project in question is a joint effort between students at Karlstad University and Marcus Norström at the company Hovercraft solutions. The project is divided into two parts, one focusing on the purely technical aspects of engineering the product and one focusing on the design aspects of the product development. The project described in this report is the design of the product. The assignment from Hovercraft solutions is regarding design engineering of a cabin for the hovercraft 380TD from the manufacturer Griffon hovercraft. The product lacks a cabin and none is offered from Griffon at the time being. 380TD is a relatively small hovercraft with a length of 6.8 metres and a width of 3.8 metres.The surface available for the cabin is not much different from the body of a car.Because of this, research has been focused primarily on car bodies.The product development process used in the project is following a systematic approach.From a chosen concept, the project was finalized with a CAD-modell as well as a detailed prototype.The weight target of 80 kg was reached and the ergonomic aspects were considered developing the sight field, roof- and entrance height. .
