The use of spread spectrum signals has increased dramatically in military applications. Finding methods for detecting and positioning of these signals have become interesting research areas for signal intelligence purposes. One method is to measure the time difference of arrival (TDOA) that occurs when two receivers are synchronous and spatially separated. Based on the TDOA-technique an audio-demonstrator has been developed and implemented. This report describes the theory for how sound received in microphones can be used to extract information about the transmitter?s position from the measured time difference.

The Saami, a Nordic indigenous people scattered over four countries, has for centuries been regarded as parts of the national populations of the countries in which they live. During the 19th century saami demands for greater influence resulted en several changes, among them the founding of a Swedish Saami Council in 1993. The council became a popularly elected, representative institution with an agenda of its own, but also a public authority answerable to the government. The decision to attribute the council this twofold role was unusual and, from a certain point of view, even controversial: it makes it difficult to determine the location of the power to act in saami-related issues and the legitimacy to do so.This essay is about how the twofold role came into existence, what it leads to and how the seemingly contradictive duality is managed. It has an institutional approach with theories concerning institutions and etnicity as well as institutional change and handling of complicated and ambiguous demands.

This Master?s thesis examines different retrieval strategies used in cross-language information retrieval (CLIR). The aim was to investigate if there were any differences between baseline queries and translated queries in retrieval effectiveness; how the retrieval effectiveness was affected by query structuring and if the results differed between different languages. The languages used in this study were Swedish, English and Finnish. 30 topics from the TrecUta collection were translated into Swedish and Finnish.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

Usability studies are not a central field of research in library and information science. Although literature in library and information science treats the importance of usable user interfaces quite extensively, the literature does not significantly treat potential problems in measuring usability. The aim of this master thesis is to investigate, through a critical analysis, the methods used when conducting usability studies in library and information science. The critical analysis is based on potential problems in measuring usability identified through a literature review from the field of studies Human-Computer Interaction, the concept of usabilitys original domain. The material which is to be analysed, is chosen from one library and information science journal Journal of the American Society for Information Science and Technology.

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.

This paper examines the existence of two different discourses on the causes of the wars in former Yugoslavia 1991-1995 in the editorial pages in Swedish newspapers. One discourse is titled "ancient hatreds" and explains the wars as a result of old historical ethnic conflicts typical of the "Balkans" and the second discourse, "poor political leadership," explains the wars as a result of deliberately conducted nationalistic policies by political leaders.Parallel to this discourse analysis is a media theory perspective of how news is selected and processed in the newspaper's editorial texts.The paper also examines the link between each discourse and a specific view on the necessity of foreign military intervention in former Yugoslavia.The starting point of the investigation are two high-profile events in 1995 and the impact they made in the 29 editorial texts in the metropolitan newspapers that were studied.The paper shows that none of the discourses clearly dominated in these editorial texts and that a clear link between a certain discourse and the advocated measure in the form of foreign intervention couldn´t be established in the material as a whole. However, the four texts that clearly belonged to the "ancient hatreds" discourse were all in favour of foreign military intervention.The essay concludes that there is evidence of a medial feedback which means that the news to a high degree influences what is discussed in the editorials and that the evaluation and selection of news, is similar in all the studied newspapers..

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

This is an empirical cross-sectional study with the aim to examine the patient?s comprehension about their quality of life within two to seven years after their stem-cell transplantation with reference to physical, social, emotional, psychological and functional wellbeing and to investigate if the patient groups have disease specific problems. Differences in quality of life between men and women and also between allogeneic and stem cell transplantation with an unrelated donor (URD) were studied.

My theoretical points concerns on having strict rules both inside and outside the classroom.

The aim of this thesis is to describe the subject indexing of images performed at the provincial museum of Jämtland and to evaluate the inter-indexer consistency at the museum. The main questions are: How are photographs indexed in the database SOFIE foto regarding Outline-codes, subject headings and natural language keywords? How does these procedures compare to research and indexing projects? How consistent are the indexers at the museum when choosing Outline-codes, subject headings and natural language keywords? Answers are sought by reading articles about classification, image indexing, indexing language, indexing consistency and by looking at a number of projects attempting to standardise image indexing practice in Sweden. The indexing practice at the museum is also described. In addition a minor inter-indexing consistency study, based on the subject indexing of ten photographs made by five indexers at the museum, is performed.

In this study, we looked at how balanced the various christian denominations in Sweden were raised in the news, on the basis of the requirement for balanced reporting. To measure the balance, we utilized Harcup and O'Neill?s news values and studied to what degree these values occurs in association with news articles that address the various denominations. The following denominations were selected for this study; Word of Life, the Pentecostal Church, Jehovah's witnesses, the Catholic Church, the Salvation Army and the Swedish Church. These denominations were then studied on the basis of news values in four of Sweden?s largest news organisations, in terms of audience numbers.
