Design av stimuligenerator för radarmålsökare
During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.
Utveckling av Flashapplikation - "Avatarskapare"
This report describes the development of an application in collaboration with Designingenjörerna AB. The company has worked for a long time with a community platform and they required an application where users can create their own unique profile representations, called Avatar Creator. An Avatar Creator is computer based application, which makes it possible to create a virtual character. The problem area behind this is that, large websites require a lot of administrative work when people upload profile pictures on different community pages. They can contain abusive material or pictures of other people rather than those who created the profile.The questions in this report are, how can an Avatar Creator help user to get a unique profile of himself? What are the advantages and disadvantages of an Avatar Creator? How to create a user-friendly application?To understand how an Avatar Creator works and get ideas to create an application, exiting Avatar Creators were reviewed on the Web.Collaborative work with Designingenjörerna AB was done to pin down the requirements for the Avatar creator application.
Hållbarhetsredovisning och media: en studie av Vattenfall ABs hållbarhetsredovisningar och medierapporteringen under en femårsperiod
Sustainability questions that concern the subjects of environmental and social aspects are increasing in today?s society, and therefore the sustainability report is a way for companies to show their work with sustainability development by working with a clear report and follow up. As the first country in the world, Sweden has decided, as from the financial year of 2008, that all governmental owned companies should present a sustainability report according to the guidelines of GRI. The aim of this essay was to identify and analyze actual events from a sustainability aspect for Vattenfall, from a medial perspective during the time period 2005-2009. We made a content analysis of one company?s sustainability reports during a time period of five years and we connected this to the medias reports of the company from the same period, to see if there were any connections between the subjects that media had elucidated.
Athena - En intelligent och flexibel säkerhetslösning för transportbranschen
The project team has chosen to carry out the project itself. This is to be able to work more flexibly in the product development process and not be guided by some guidelines.Every day, we read in the media about a new truck burglary. The problem has become so common that we do not even notice it in the media. Each year the theft of 1 billion of Sweden and the entire 82 billion in Europe in 2008. This is an increase of 10 billion by 2007.
Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Design av PID-regulator baserad på kommersiell processormodul
The idea to develop a platform for a PID-controller came from the need to control the temperature in an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

The purpose of this essay is to illustrate the importance of the school library in a selected junior high school. My investigation is based on both theoretical and empirical studies. The aim of the theoretical part is to create a platform and refer to thoughts, roles and laws concerning the activity of the school library. The empirical investigation consists of two parts: questionnaires among students and teachers, plus interviews with students, teachers, headmaster, school librarian and the management of education. Everybody shows a positive attitude towards the school library and considers it important for the students exams.
Vad händer med åsikterna? : Järvadialogen som kommunikationsinsats
The area of Järvafältet in the northern parts of Stockholm is one of the many large-scale investments into Swedish residency executed in the 60?s and 70?s, and which got the name Miljonprogrammet. Not until today these buildings have been restored, and frustration has been brewing in these areas for some time. Järvadialogen is the name of a communication program connected to the housing restoration in the area of Husby, which is a part of Järvafältet, and functions as a promotional and informational dialogue between residents in the area and those responsible for the communication program. The cultural diversity in the area of Husby is significant, and with theories on intercultural communication, change communication and power we study the performed communicative process and the manner in which it is received.

Skolbiblioteket ? definition och användning: en innehållsanalys av gymnasieskolans styrdokument 2012
The purpose of this thesis is to systematically describe and map how authorities define the school library and its function based on the current policy documents for the Swedish upper secondary school. The study is guided by the following questions: ? What dimensions does the school library have according to the explicit definitions, descriptions and requirements? ? What implicit arguments, references and unspoken assumptions about the school library and its role, function and significance can be derived? The study is delimited to the national policy documents, which have been divided into two groups ? structural and teaching focused ? corresponding to the two questions above. Further delimitations have been made to avoid noise and to manage a manual content analysis. Each question required its own analysis tool.
Utveckling av metoder att mäta centrering av skruvhål i skär
There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.
