Undersökning av elektroniska scorekort på golfmarknaden : Var ligger problemet för fortsatt utveckling?
This is a Master´s Thesis based on my own idea instead of that of a company. It is a survey that focuses on finding out more about which part of the development process that is blocking the establishment of electronic scorecards on the golf market. Why has it not been introduced on the market in a larger scale yet, considering the technology we possess today? This question is investigated through interviews with the Swedish Golf association, and three companies that have chosen different paths to implement an electronic scorecard. The interviews focuses on finding out what developers and the association believe to be the main problem, before taking the next step in releasing electronic scorecards on a larger scale.

They manufacture their products according to the assembling for costumer order principle.The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB.
Utredning och implementering av en prototyp för integration av Prevas FOCS och ABB 800xA
ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.
Den flerspråkiga bibliotekskatalogen: Hantering av icke-latinsk skrift på bibliotek
The main purpose of this thesis has been to investigate librarians opinions about the need for and possibility to use non-roman script in library catalogues. We have also investigated the routines of handling materials in non-roman scripts in two Swedish libraries. The investigation was made in the light of the recent shift in character set in the Swedish National Library Catalogue Libris. This change will enable use of multiple writing systems in the future.Our findings are that a multicultural society requires special consideration to the needs of citizens who speak other languages than the majority of the population. This becomes difficult when the languages spoken have a different writing system than the one used by the majority.
Sensorer och system i mjölkkobesättningar : en litteraturstudie
The trend in milk production is similar in Sweden and across the world; the farms are getting fewer but increasingly bigger. The costs for hiring workers are increasing, which results in more cows per animal keeper. Sensors can then be a great tool for keeping track of animals which need special attention. With a reported decreasing fertility, sensors that can detect oestrus even at low levels can be especially helpful in bigger herds to pinpoint the cows that may be in oestrus. The number of farms with dairy cows that install AMS, Automatic Milking Systems, are increasing, and that also increases the need for sensors to control milk quality and composition when there is no visual control of the milk by a milker before milking starts.For the sensor data to be useful you have to have software designed to analyze and interpret the data to get relevant information that the farmer can use.

1553-Simulator. In-/uppspelning av databusstrafik med hjälp av FPGA
At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).
Metoder att förhindra nedisning av vindkraftverksblad
ABSTRACTMany wind turbines have problems with icing and there is still no effective method to de-ice without stoppage of production and power loss. Here I therefore consider other methods than those available today, and particularly, I consider how these methods could be applied to wind turbines of the company Oxel. A surface where the water droplets do not attach might be the basis for a useful method. If no water attaches, no ice could form. To accomplish this a hydrophobic surface is nessesary, for example wax.
Termisk Vattenpump
This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. The degree project's goal is to find an economically viable alternative to the time consuming hand-powered water pumps. The power comes from solar energy.
Simulator för el- och värmeproduktion : påverkan på ekonomi och miljö
In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely.
The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished
the result is graded in the following categories: economy, environment and quality.
To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.
Implementation of renewable energy in the Republic of Moldova : society and landscape in transition
The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing
a phase of transition in both society and landscape. They have hardly any fossil depots and
are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected
government wants to move towards the EU and this is generally seen as the way to grow and reduce
poverty. Security in the energy sector is important and one tool is to increase the use of renewable
energy sources.
Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in
Moldova through a society development perspective. The study has aimed to investigate the sociotechnical
complexity of this subject and to discuss the potentials and way of dealing with the subject in
the specific cultural context of Moldova.

Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.
Hedersrelaterat våld och förtryck : en kvalitativ studie om professionellas erfarenheter av utslussning från skyddat boende
The aim of this study was to understand how social workers deal with honour-related violence, with special focus on the processing from sheltered housing. Our qualitative interviews with social workers that work with this kind of problems show that there are both obstacles and opportunities in the processing from sheltered housing. On the negative side are the loneliness, the shame and the guilt that the girls may experience when they need to leave their families. The social services can both be an obstacles and an opportunity. When the girls need to create a new life in a new city they have a lot of opportunities and in the same time it is hard to get to know new friends when you don´t know the city or have much money.
