Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Romer i samhällsdebatten : En kvalitativ studie om framställningen av romer i debattartiklar
The purpose of this study is to investigate the medial portrayal of Romani people in the newspaper Dagens Nyheter from 2013 and 2014.

Historiska återspeglingar : En studie om svensk turismhistoria genom fallstudier på Åre och Mölle
The idea of this thesis emerged from our common interest to explore the life cycle of Swedish tourist destinations. This study has historical features since we tried to identify crucial historical and current push and pull factors, which influenced destinations upturns and downturns. In order to achieve our primary goal and identify those factors, we made two case studies. We chose Åre and Mölle as our cases and these two areas will represent Swedish destinations, and their life cycles, as a whole. The destinations? developing processes and their nowadays profile are not the same as for two hundred years ago which was a reason and motivation that made us start exploring this specific subject.
Patienters skattning av hindrande smärta och self-efficacy före och efter diskbråcksoperation
Objectives: The purpose of the study was to examine if a pre- and post-operative difference could be seen in self-reported pain disability and self-efficacy among patients undergoing surgery as treatment for spinal disc herniation in order to improve process of rehabilitation.Method: A quantitative and descriptive design was used. 10 patients awaiting surgical treatment for spinal disc herniation were included at Akademiska sjukhuset (The Academic Hospital) in Uppsala. Participation was voluntary and the selection was made by convenience. Data was collected using The Pain Disability Index and Self-Efficacy Scale by which the patient would estimate how hindered they felt because of their pain in everyday activities and their self-efficacy to perform everyday activities. This was done the day before surgery and two weeks after surgery.
Synen på värdering av Itsystem. En kvalitativ studie av IT-investeringar i fyra kommuner i Västra Götaland
When a municipality is about to realize an IT investment, e.g. an economy system, theywill need to do procurement according to the laws of procurements. To perform suchprocurement takes time and energy from the everyday work at the municipalities, andtherefore they want to make a quick and efficient procurement. Unfortunately it showsthat municipalities do not always make an assessment that is sufficient enough for theirneeds, which can result in an inefficient system in a longer perspective. Municipalitiesthink more often about the hard values such as costs of the investments, and not alwaysas much when it comes to the soft values, like the user-friendliness.

Musikbranschens syn på folkbiblioteken. En aktör att räkna med?
This thesis explores the opinion of different participants in the music business regarding music being made available at the public libraries. The aim of the thesis is to answer the following questions; which are the most important issues concerning the distribution of music? How do the informants perceive the public libraries mission and activity in regard to make recorded music available? Which are the benefits/disadvantages with music being made available at public libraries? Seven qualitative, semi-structured interviews were conducted with representatives from the following organisations; SKAP (The Swedish Society of Popular Music Composers), FST (Society of Swedish Composers), SAMI (Swedish Artists and Musicians Interest Organisation) SMF (The Swedish Society of Musicians), SOM (Swedish Independent Musicproducers), IFPI (International Federation of the Phonographic Industry) and EMI Music Sweden. A study of literature and articles generated nine themes, which constitutes the frame of reference for the thesis. The result shows that several of the informants have not reflected upon the public library as an important actor when it comes to the distribution of music.
Levande material. En utforskande exposé över vårt förhållande till kroppen som organisk materia
In this project the author made an attempt to, in a short film, visualizean experience of the organic materials that our bodies consist ofand what becomes of it when we die. The intention was to dissect thismatter, break it down to see it in a simpler form and to explore ourrelationship to it, being part of a constant exchange between organicmaterials and having so much power over the environment and otherliving animals. At the very start, the idea was to deal with the relationshipdifferent people have with their bodies. Later in the process, a decisionwas made that the product would be communicating the author?sown experiences of the body materials after studying it and trying torecreate fragments and feelings of them.
Ekonomisk och teknisk uppföljning vid anläggningsprojekt : För möjlighet till bättre erfarenhetsåterföring
Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

Kapsprickor och avverkningsaggregat
This study was made for the Swedish forest company Sveaskog because the sawmills they delivered timber to had noticed a high frequency of bucking splits in their products. Coworker Jim Edström at Sveaskog also wanted to know if there was a big difference between different felling heads. The purpose with this study has been to find out the amount of bucking splits and if there is any felling head brand that did a bigger damage that the others.
The study was made in two steps, where the first part was a literary review to find out results and conclusions in earlier studies. The best measuring method to check bucking splits was the known ?trissmetoden?.
