Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor
This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
NATURMINNENS F?RVALTNING OCH SKYDD: Inventering i V?stra G?taland
Natural monuments are natural objects with special protection due to their high natural value or cultural significance. The natural value is determined by the occurrence of signal species found on and near the natural monument. The law surrounding natural monuments has evolved a lot since the first ones were declared, and today the title natural monument can be replaced with the title tree with high conservation value. The title has come later and can sometimes overlap natural monument. Some natural monuments lack the qualities required to be classified as a natural monument or a tree with high conservation value, but have a cultural importance.

This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.
ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Radiolänk med GNU Radio
At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

Intern materialhanteringsutveckling på Kongsberg Automotive AB
This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

The signal strength(RSSI) has been read in the configuration menu of the broadband routers as well as in the cellphone.The conclussions drawn:Net1s net appears to be more used compared to its capacity than the other netsTele2s net has a high and even data rate where it?s signal strength is sufficient.
Uteservering för Hotell & Restaurang Villa Anna : urban odling i uteserveringsmiljö med storytelling som gestaltningsverktyg
In this paper, I design a new concept for a patio at Hotel and Restaurant Villa Anna in Odinslund, Uppsala, Sweden. Through this design, I examine how urban farming can thrive in a restaurant-context. The purpose of the design is to give the visitor a sense of the core values of the cuisine and to strengthen the sense of place by storytelling. My methods are comprised of a literature study on urban farming and storytelling as well as a discussion with the res-taurateur Rafael Löfstedt. I create a story of the place by examining its historical background and connect it to the current philosophy of the Villa Anna restaurant.
Internetbaserade insamling och behandling av data
AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Risker och hot i det nya samhället : En diskursanalys av repporteringen från morden på Olof Palme och Anna Lindh i kvällspressen
I uppsatsen kommer det fram att människor är mer medvetna om risker och hot än vad de var för 20 år sedan. Detta framkommer genom att artiklarna som analyserats angående mordet på Olof Palme var mer inriktade på hur chockerande det var för Svenska folket och hur oväntat ett dåd av detta slag var. I artiklarna angående Anna Lindh var människor även där chockade över dådet men det chockerande var i stället att det kunde hända en gång till i Sverige. I de artiklarna har koncentrationen mer legat på gärningsmannen och polisens arbete.I och med detta kunde vi se att befolkningen i Sverige lever med en större medvetenhet om de risker och hot som finns omkring dem i samhället. Detta stämmer väl med de teorier som uppsatsen tar upp om att det finns risker och hot som en del av vardagen på ett annat sätt än för 20 år sedan..
En nationell sorg En analys av effekterna av mordet på utrikesminister Anna Lindh utifrån ett nationalistiskt perspektiv
In September 2003 the Swedish minister of foreign affairs Anna Lindh was murdered. The murder shocked Sweden and the picture of a safe homeland was challenged. The Swedish people joined together in different manifestations and rituals to show their appreciation for the minister and to mourn together. A few days later the nation was going to vote on whether Sweden should join the euro and the minister was involved in the campaign. The aim for this thesis is to understand how this national crisis was handled in Sweden.
"The history books tell it, they tell it so well" : Minoritetselever och historieundervisning i den svenska gymnasieskolan
The purpose of this study is to analyze different aspects of a portraying of individuals from a time past. It is concentrated around questions about why it is important to show the people?s stories in, for example, exhibitions and under which conditions this would serve as a good use of history according to different theories about history and the portraying of it.I have chosen the theories of Freidrich Nietzsche and Georg Simmel as a tool to analyze different aspects of the portraying of people from the past. Nietzsche?s theory about the different ways in which we use the past and Simmels theory about the meeting between a viewer and a cultural experience.
Kombinerad DSP- och FPGA-lösning för en bildbehandlingsapplikation
This Master's Thesis describes the design of a new system where a digital signal processor has been added to an existing imaging system consisting of field programmable gate arrays. The new system will offer a higher degree of flexibility by considerably shortening the design time and make it possible to implement more complex algorithms than the existing ones. The choice of system architecture and a test implementation are discussed. The test implementation consists of a program for the digital signal processor and VHDL code for one of the field programmable gate arrays. The code for the digital signal processor was designed for testing on an evaluation board from Texas Instruments.
