Konstruktion av en autonom vindstation
Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

AbstractBachelor Thesis, School of Economics at Vaxjo universityProgram: Enterprising and Business Development, EBD 362, Spring 2006Authors: Jens Asp, Vivianne Holmer, Carl-Marcus WahlstromExaminer: Stig G JohanssonKeywords: Services, cooperation, collaboration, customer offer, knowledgeTitle: Service firms in collaboration ? A study of the development of small service firms in collaborationNutek presented numbers during year 2005 witched show that the Swedish service sector, for the first time ever, was greater than the industrial sector. The kind of firms that develop most is small service firms without employees. The topic of interest in this bachelor thesis is to study how this kind of firms can develop. There is a great number of strategic options for firms to choose.
Det lärande mötet : En studie om lärares didaktiska medvetenhet i undervisningssituationer
The authors were curious and asked themselves if teachers are aware of the base of their teaching in various teaching situations. Are teachers at all capable of expressing that in words? One of the reasons that the authors chose the particular issue was because they think teachers have the task to satisfy the needs of all students and therefore they found it interesting to study how various teachers act. The purpose of the study is to observe teachers didactical awareness, and how it can be added to their intentions and actions, as in how they speak about their teaching and how they act in various teaching situations. Methods used in the study were observations and qualitative interviews.
Studie av 3-dimensionella sidoeffekter vid etappvis schaktning i Götatunneln, J2
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

Småskalig vattenkraft vid Olofsfors bruksmuseum : Med faunapassage
In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Företagsvärdering i praktiken : Hur bör en säljare agera vid företagsöverlåtelse?
It is important to understand the process of appraisal of a business in order to establish its value. The purpose of our thesis is to establish which methods and models are used when evaluating a business and investigate the factors that may affect the value and price tag of a business. We have used a qualitative approach by conducting both indepth interviews and a survey as well as reading literature within the field. The main conslusion in our findings is that the common practice of discounted cash flow is widely used when bestowing a monetary value for a business, and in order to raise the value a well established customer relationship was the single most important factor. As far as lowering the value, the answers were of such a wide spread that a single factor could not be attributed.

Levbart transportsystem i Uppsala
In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.
"Kristen etik och västerländsk humanism" - historiskt förankrade begrepp eller uttryck för en suverän etik? : En undersökning kring resonemanget rörande begreppen i förarbetena till läroplanerna Lpo/Lpf 94
The purpose of this study is to examine discussions held by politicians and experts concerning the concepts Christian ethics and western humanism. I will examine the argumentation for and against the concepts Christian ethics and western humanism, which finally ended in a resolution of using these concepts in the curriculum Lpo/Lpf 94. In this study I am using a qualitative method to examine how different opinions and views are expressed in two different committee reports, initiated by the Ministry of Education, as well as protocols from the debate in the Swedish Parliament.I will attempt to elucidate the political views of these concepts, which will become an integral part of the base of values in the curriculum. Results show that the politicians are unanimous regarding the content itself, but disagree of the thought of establishing the base of values in Christian ethics. But the discussion is ambiguous because the opinion of the politicians is that the concepts, especially Christian ethics, stand for general human values.

Mikrofonkonfigurationer bestående av en eller två mikrofoner vid inspelning av elgitarr
This C-essay focuses its research on the taste of guitarplaying and non-guitarplaying soundengineers, in using single or dual microphone setups when recording electric guitar. It will be shown if there is a significant difference in taste when using one or two microphones between the two testsubject groups. Two classical microphone setups have been used for the test of this essay, which includes a blind listening test. The information in this test will benefit both guitarplaying and non-guitarplaying engineers by getting greater knowledge regarding what kind of microphone setups to use for different occations. The findings in this essay show in general, that guitarplaying and non-guitarplaying engineers between the ages of 19 - 26 don?t have a specific taste between single or dual microphone setups when subjected to the blind listening test..
Exponering för rörelser och emotioner - : En DBT-inspirerad exponeringsbehandling för människor med långvarig ländryggssmärta.
SammanfattningLångvarig smärta orsakar stort lidande för individen och belastar samhället ekonomiskt. Syftet med denna uppsats var att undersöka om en exponering in vivo-behandling inspirerad av Dialektisk beteendeterapi (DBT) för människor med långvarig ländryggssmärta var görbar samt om behandlingen gav effekt på smärtrelaterad problematik. Designen var en single case experimental design vilket är en beprövad design för att testa nya terapimetoder. Studien bestod av sex deltagare, alla med hög grad av smärtrelaterade katastroftankar, något som litteraturen visat predicera sämre behandlingsutfall. Behandlingen var DBT-inspirerad och indelad i tre faser; en första valideringsfas, en andra färdighetsfas och en tredje exponeringsfas.
