In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

The goal of customer support is to help clients achieve maximum value in their services and products. Customer support is the public face of a company, which means that it is important to give the customer a positive experience and live up to customer expectations. Efficient customer support has become more important and studies show that customers who leave a company do so because of poor service. Customers' growing demands for higher quality and easier access to services means that companies must recognize the need to satisfy each customer. It is important that each customer receives the attention required and that customer needs are met quickly and flawlessly.

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

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.

To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.

On the 10th of February 2011 Hosni Mubarak gave his last speech as the president of Egypt, on the following day he resigned the presidency after more then two weeks of violent protests against his rule, and with that his 30-year long rule over Egypt had come to an end. This bachelor thesis aims towards examining this speech using both qualitative and quantitative research methods in order to reach a useful analysis of the speech. The conclusions of this thesis is that several methods were used in the speech in order to win the listeners acceptance and approval for the speaker, and then to use these in order to soothe, or preferably to completely stop, the current revolution. The methods that have been found to play major roles in achieving this are; portraying the speaker, defining the listener, promises of improvements and of justice/revenge, and nationalism. This thesis is written in Swedish with Arabic excerpts..

Whist is one of the most played card games of the world. Though there have been many studies made in the field of game theory, whist is still somewhat of an unchartered territory. In this thesis some methods to obtain an optimal strategy for whist are discussed. Whist belongs to a group of games called logical games. For this group there exists algorithms which result in an optimal strategy.

Utvecklingen inom informationsteknologi (IT)-området har gjort det möjligt för företag att distribuera tjänster och mjukvara via webben, enligt affärsmodellen Software as a Servie (SaaS). Det har dessutom visat sig att det finns ytterligare vinst att göra för såväl konsumenter som leverantörer av dessa verktyg om de kan distribueras utan omfattande implementeringsaktiviteter och utbildning. Därför vill man uppnå en hög grad av self-service i applikationerna.Affärsprocessföretaget Barium AB har uppmärksammat denna potential hos SaaS-produkterna och hyser en önskan att implementera self-servicetänket i deras produkt ?Barium Live!?. Då den forskning som finns rörande design av self-serviceprodukter i huvudsak handlar om enkla system av kiosk- och automattyp har de tagit initiativ till detta arbete för att reda ut vilka designimplikationer self-serviceaspekten har för mer komplexa applikationer.

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.

This is a report founded on a project by Atlas Copco called NYSTAB.  The application Nystab is a calculation program that can calculate the stability of the rockdrill-rigs made by Atlas Copco. The original version of Nystab is stored in a database from 1997 and the code is made in an old version of Visual Basic. My assignment was to develop the application in to a newer programming environment and make it last better in the upcoming years. The software I decided to use to accomplish this project is C# .NET in Visual Studio and Microsoft Access 2010. All the code is written in C# with some insertions from ADO.NET which helped me to easier connect the code with the database.The coding part was split into two pieces; the first was to develop the application scale done with Windows Forms, the second was to write the code for calculations in the application.

This Master Thesis has been carried out in cooperation with Silva Sweden AB. A companywhich manufactures products like compasses, pedometers, headlamps, hiking poles and otherequipment for the out door life and navigation. The purpose of the project has been toassemble methods and models which support user involvement in Silva?s design process.Thus, to increase the number of products with purchasing power, enhance product quality aswell as increase foundation for new product ideas.The focus through out the project has been to assemble a pallet with methods for userinvolvement and from this select a few methods that will fit the company. The purpose of thepallet is to be accessible for the company during their work of change with the design processthat has been going on and will be in the future.

The Master Thesis has been carried out in cooperation with Silva Sweden AB and the objective was to develop a new product concept within the product category for everyday exercise. The purpose of the thesis was to use and analyze methods and tools which aid creativity and concept creation in order to make method recommendations for future projects.During the thesis a number of customer needs were identified, which in turn were translated into 20 concepts. On a concept decision meeting a pedometer-based concept was chosen for development. The new pedometer is in addition to counting steps also able to measure and calculate the user?s total climbed height during a day and present this graphically in comparison to famous monuments or distances.

The purpose of this thesis has been todesign an electric circuit that measurestemperature in three different ways. Asoftware was also designed to record andanalyse the measurments. The result of thecircuit was a PCB with inputs for 42sensors of both surface and non-surfacemeasurments. These all have a maximumerror of ±3°C..

This report is introduced with a presentation of fundamental electromagnetic theories, which have helped a lot in the achievement of methods for calculation and design of microstrip transmission lines and circulators. The used software for the work is also based on these theories. General considerations when designing microstrip solutions, such as different types of transmission lines and circulators, are then presented. Especially the design steps for microstrip lines, which have been used in this project, are described. Discontinuities, like bends of microstrip lines, are treated and simulated.
