At Saab Aerosystems, situated in Linköping Sweden, there is a presentation and manoeuvre simulator simulating the fighter jet JAS-39 Gripen. This flight simulator is called PMSIM. In this thesis we study how to transfer sensor images generated by PMSIM to other simulators or desktop computers. The transmission is band-limited so some kind of Image Coding must be used. Because of this the greater part of this thesis is concerned with Image Coding.

This thesis explores the possibilities of avoiding the issues generally associated with compression of noisy imagery, through the usage of vector quantization. By utilizing the learning aspects of vector quantization, image processing operations such as noise reduction could be implemented in a straightforward way. Several techniques are presented and evaluated. A direct comparison shows that for noisy imagery, vector quantization, in spite of it's simplicity, has clear advantages over MPEG-4 encoding..

This master thesis has been done at Enea Epact AB. The purpose of this thesis is to develop and implement a Link Quality Control algorithm for GPRS/EPGRS in the current testing tool. A Link Quality Control (LQC) shall take quality values from mobile stations and base stations and decide a codingsscheme that opimizes the throughput of data. The Advantage with LQC is that it adapts the used coding scheme to the channel quality. If the channel quality is too bad for the used coding scheme, a slower coding scheme with more redundancy should be selected.

This thesis discusses the possibilities to distribute digital video in a military vehicle. Today, an analogue system is used, which has a maximum capacity of eighteen video sources and the same number of monitors. The purpose of this thesis is to increase the systems capabilities regarding secure distribution and additional functions. Both software and hardware tests are made to investigate the features of the digital video standard MPEG-2. Both the coding delay and the image quality are of great interest.

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Bacteria are exposed to evolutionary pressure to an extent unlike other organisms. This leads to a high degree of adaptation to its surrounding. This thesis investigates the degree of adaptation towards higher accuracy in the transcription of DNA to RNA in coding sequences in the DNA of the E. coli bacteria. Two coding sequences with different nucleotide contents were investigated.

Uppsatsen behandlar problematiken om när ett varumärke ses som en symbol för produkten eller för en image, t.ex. en livsstil. Berör ett företags mission och vision, symboler och tecken, varumärkets image och konsumentens image samt produktens och varumärkets livscyklar..

Syftet med studein är att studera Coding Technologies och hur det som litet företag har etablerat en högteknologisk standard på en marknad dominerad av stora aktörer. Resultatet av detta ska vara att identifiera viktiga faktorer och visa på strategier ett litet företag kan använda i denna situation. Studien är genomförd i form av en fallstudie med djupintervjuer där den teoretiska referensramen arbetats fram utifrån empirin. Uppsatsen behandlar de teoriområden som förknippas med standardsättande. Områden som nätverksmarknader, nätverk och patentproblematik.

The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves? We want to examine in what way social relationships are important and how they function for individuals who harm themselves, both once they have started to harm themselves, and if the relationships in any part caused the cutting to begin with.Questions:How do individuals shape their identity based on self- harm? Which self-image do individuals have who self-harm? Is there anything in the person's previous social relationships that have caused them to begin to hurt themselves?Method:In this paper we have analyzed five autobiographies. We have used open coding from grounded theory as analytical method and subject positions based on discourse analysis.Theory:We have used the Cooley concepts looking glass self, Foucault's theory of power, Giddens' concept of ontological security and existential anxiety.Results and Analysis:We found six different categories that we thought were central. These were negative self-image, guilt, lack of family support, negative experiences of others' views, the protective identity as self- harmer and insecure social relationships in school.Conclusion:The self-harming is a very complex behavior.

This essay was to investigate what self-image public libraries convey on Facebook and what image is received by the users, along with comparison of those. It was investigated if the received image corresponded with the users? previous image of public libraries. The method used was interviews with the Facebook administrators and surveys with the users. The theoretical framework was Kotler?s model for image creation.The research is mainly American and shows Facebook as an accepted marketing tool for libraries among students, but as not taken seriously by the library staff.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

A report on my thesis developing an algorithm to automatically classify a mammogram image as containing an implant or not and segmenting and masking any present breast implant in the image..

Background: The business market today is characterized by tough competition amongst the competitors to capture consumers? interest and money. One marketing tool companies can use to achieve this is the company?s image. The customer buys not only a product, but also the image that the company or the product is associated with.

Companies spend huge amounts on communicating their brand through marketing. Many of these contact areas where the consumer comes in contact with the brand is con-trolled by the company. The brand image is also affected from outside the company. It can be from users, media, blogs etc.Burberry is an example of a company that got in trouble with their brand image after hooligans where associated with their products. If a company with a brand with a strong image is associated whith consumers that are not compatible with the target group the company wants, there is a risk of a negative affect on the brand image.Our purpose is to investigate and describe the phenomenom when a company brandimage is affected by being associated whith consumers not compatable whith, by the company, intended target group.We have chosen a qualitative research where we use a multiple case study.
