En studie av olika ekonomiska modeller för mångbruk baserad på vindkraft
Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden?s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will leas there land for wind power to wind energy companies. Such land leasing means that the landowner's business is considered to be a multiple-use.
Luftfartsverket till LFV : En studie i ett förnyande av ett varumärke
The 1st of January this year the state owned Swedish Luftfartsverket changed their name into the shorter name LFV. The shorter LFV is a more modern version in terms of that the name is a proof of that the classic organisation of the state, Luftfartsverket, with this stepbreaks through boarders and finds new ways. Plans have existed before but since 2005 when Luftfartsverket lost its assignments from the government and become a state owned business corporation, the plans have intensified. Now, also for all the employees, it isgetting obvious that something is going on in the organisation.The purpose of this paper is to see how this newly made change of name and logotype have been recieved and how it has effect the strategic choosen respondents within the organisation LFV. These choosen respondents have thorough knowledge of the organisation of LFV.

Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.
The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..
Energianalys av Svensk Växtkrafts biogasanläggning i Västerås
Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase
their treatment capacity at their biogas plant. In connection to this work it is also possible to make
some energy saving changes to the biogas plant. The objective of this study was therefore to make
an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the
sanitation step and also a comparison of energy consumption with the present sanitation method
and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method
is heating to 70 °C during 1 hour).
The energy survey was conducted in close collaboration with staff at the biogas plant. The current
during normal operation was measured, power was calculated and multiplied by the time of usage to
obtain the energy consumed.
IT-kompetens : utveckling av ett mätinstrument
Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies. Then need for people with IT-competence is conquent increasing. A survey of corporate IT-competence is therefore of interest for companies as well as for local authorities. To determine the IT competence within an organisation, this competence has to be measurable.
Aerodynamisk optimering av vindkraftverks rotorblad med en genetisk algoritm, BEM-teori, och XFOIL
This study presents a methodology that enables the annual average power of a wind turbine to be increased by automatically optimizing it?s airfoil, twist and chord dis- tribution. As a part of the study the software SiteOpt has been developed. This software connects the open source software XFOIL with the blade element momen- tum theory. XFOIL gives lift and drag coefficients which enable the blade element momentum theory to predict the power of a wind turbine at different wind and ro- tational speeds.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
Feldiagnos för RM12 baserad på identifierade modeller
The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

Positionering av industriella tjänster
This thesis aims to investigate the positioning concept of industrial services. We chose to identify the reasons why positioning is used as well as to describe the positioning process. The research strategy chosen for this thesis was a case study of a consultancy firm Benima AB. This firm was chosen due to the fact that a new positioning concept during the latest year hade been implemented and therefore seemed like a good choice for our study. Of the six available theoretical reasons for positioning, we found that Benima AB had two of them: namely change in target market or their needs and demands and renewed company identity/personality.
Planering och anläggning av en uteplats i parhusområde :
In a condominium with two-apartment buildings, lies an area, formerly used as a playground, nowadays wasted and abandoned. The owner wanted to embellish the place and get a new use for it, preferably as a gathering- and feast-place. The work is described with focus on the construction with describing pictures and sketches. The production of the sketches is not reported more than that they are attached at the end of the paper. The practical work is done and documented.
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.
Uppamma mod och utjämna makt : Ett aktionsforskningsprojekt där arbetsredskap utformades tillsammans med sjuksköterskestudenter för att kunna lindra för personer att leva med ovisshet.
Uncertainty is a well-known phenomenon that is recurring in biographies, imaginative literature and science, but is less studied in nursing science. The aim of this participatory action research project was to, in collaboration with nursing students; explore nursing activities for relieving patients? uncertainty. A qualitative approach was chosen with focus groups and the text was content analyzed. The students studied their third semester on a nursing program.
