Vindkraftsacceptans i olika etableringsfaser. En jämförelse av acceptansnivån i tre områden inom Mariestads kommun
The purpose of this paper is to contribute to a deeper understanding about the acceptance of wind power. Our basic assumption is that local conditions are important and can explain how the acceptance of change at different stages of establishment. The main purpose is to see if there are differences in the acceptance of wind power in different stages, and examine the factors that influence acceptance. That includes how people in three different areas of study estimates that they value their environment and how it is affected by wind turbines. The project was conducted interdisciplinary geo-targeted and consists of three parts.
Informationsdesign i hemmets hjärta : Struktur och ordning i kök för personer med neuropsykiatriskt funktionshinder
Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.
Utökning av mätområdet för turbinverkningsgraden på avgasturbo
The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.
ISIT-modellen : Vägledning för att realisera en verksamhets informationssäkerhetsmål
The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.
Passande svårighet? : Spelares uppmärksammande av och attityder till dynamisk svårighetsjustering
Syftet med detta arbete är att undersöka hur dynamisk svårighetsjustering påverkar hur spelare värderar ett spels svårighet, presterar under en spelsession och huruvida de kan upptäcka ett system för sådan justering samt identifiera hur det fungerar. Arbetet vilar främst på Robin Hunickes arbete kring dynamisk svårighetsjustering men vidrör även koncept som svårighet, flow och olika typer av svårighetsjustering. För att undersöka huruvida system för dynamisk svårighetsjustering påverkar spelande har ett plattformsspel utvecklats och speltestats i två versioner av en handfull respondenter, en version som justerar svårigheten i spelet dynamiskt och en som balanserats för hand. Resultatet från dessa speltester ger inga direkta stöd för att dynamisk svårighetsjustering får spelare att prestera bättre och tyder på att spelare vid en första spelomgång har svårt att identifiera system för dynamisk svårighetsjustering. Resultatet visar dock även på att mer undersökningar kan behövas på ämnet i framtiden..
Fuktsäkert byggande : Sjönära bostäder i Östra Hamnen i Västerås
Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.
En krattad manege för kreatörer : Att leda och motivera kreativa grupper i kreativa processer
This essay is focusing on leadership and motivation in the creative process. The perception on the leadership has changed over time. Today?s leadership theories suggest that the leadership should be adapted after the organisations conditions. Due to the increasing globalization, companies are forced to operate in an increasingly competitive market.
Fuzzy Front End: en litteratur review
Denna uppsats behandlar första fasen i produktutvecklingsprocessen, det vill säga Fuzzy Front End (FFE). FFE är perioden från att det finns en möjlig idé och företaget anser att den är värd att utforska ytterligare, till dess att idén är godkänd och företaget är redo för att börja utveckla samt investera i projektet. I litteraturen anses denna fas som kritisk därför att den är problematisk samt avgörande för företagets fortsatta aktiviteter inom FFE. Forskningen har visat att det finns ett samband, att om företaget effektiviserar FFE bidrar det till framgång för den nya produkten. Det finns liten förståelse vad som verkligen försiggår i FFE fasen och i denna Litteratur Review har 12 stycken teman identifieras för att redogöra för FFE.
Ideation through visualization : ? The use of Storyboard as a preparing tool
ProblemIdeation in group is used by many, often as a tool for creating new and innovative ways to solve problems and creating change. Groups may have difficulties to move from the phase of inspiration to the phase of ideation, if information and ideas aren?t defined in the team.The authors claim that this process can be helped by providing practical tools that are adapted and tested for the purpose. The reason is to foster concretization of volatile thoughts in form of inspiration and information.PurposeThe study aims to investigate how Storyboard as a tool can be used to concretize thoughts and inspiration in a group before ideation.MethodIn order to collect empirical data the authors along with four other facilitators, conducted 24 DO TANK:s for the innovation contest Smart Lunch. The empirical data where then analyzed using theories related to the topic.
DCF-modellering vid multipelvärdering: En empirisk studie av hybrida värderingsmodellers prediktionsförmåga
Today, there are a number of different models and methods used to estimate the equity value of a company. A common tool for valuating stock prices is the usage of different multiples. This is a method used to determine the value of a company, by examining and comparing the financial ratios of relevant peer groups. The disadvantage with this method is that it does not take all the important aspects, such as risk, investments and capital structure, into consideration. However, this study investigates if the key value, called discounted cash flow (DCF), can be integrated with the valuation of the multiples.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde
Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.
Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :
Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals.
A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact.
Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial.
The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.
Informationsutbyte från BIM-modeller : Från BIM-modell till format hanterbara av förvaltning- och GIS-system
BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.
Hur kan det flöda bättre? : Flow-teorin som hjälp i komponerandet och musiklivet
Syftet med det här arbetet var att gestalta fem olika känslor inom genren symphonic metal. Därigenom ville jag avgöra vilka verktyg jag kunde ha nytta av i framtiden för att gestalta känslor musikaliskt och vilka skillnader som finns mellan att gestalta olika känslor. För att göra detta använde jag mig av referenslyssning av tio låtar plus några orkestrala stycken per känsla. Resultatet av lyssningen, tillsammans med olika låtskrivningstekniker, litteratur, Kirnbergers intervallkaraktäristik och Matthesons tonartskaraktäristik, användes till att skriva och arrangera mina fem låtar. Resultatet blev att jag hade lyckats skildra känslorna bra med den metod jag hade använt, men att intervallkaraktäristiken och tonartskaraktäristiken var onödiga; det skulle räcka med mina kunskaper som jag hade förvärvat under utbildningen, referenslyssning och min känsla som låtskrivare. Jag kunde inte heller urskilja några skillnader mellan att gestalta de olika känslorna; metoden var universellt tillämplig..
