Diagnosis means detection and isolation of faults. A model based diagnosis system is built on a mathematical model of the system. The difficulty when constructing the diagnosis system depends om how the model is formulated. In this report, a method is described that rewrites the model on such a form that the construction of the diagnosis algoritm is easy. The model is transformed by two state space transformations and the result will be a system on state space form where one part of the system becomes easy to supervise.

The main purpose of this Masters thesis is to examine gender division in public libraries by reviewing literature and interviewing eight public librarians and two chief librarians. The reason why we decided to investigate this topic is the lack of research concerning sex-segregation in library and information science. By choosing this subject we intend to deepen the understanding of the significance of gender both within the public library and of the occupation in general. Some researchers claim that the low status of librarianship is a result of the large proportion of women in the profession. We want to find out how our informants view the relation between professional status and female domination.

This Masters' thesis is a study on the information behaviour of hospital personnel at the University Hospital in Lund, Sweden. A questionnaire was distributed to 301 nurses and physicians working in the intensive care unit, the population was reduced to 244 persons. The response rate was 52%, i.e. 125 questionnaires were completed. Nurses constituted 68 % of the population.

This Masters thesis aims at presenting a picture of, and critically examining, the Swedish debate concerning the public library and the future by way of 21 articles in three library periodicals. The questions examined are: -What are the views concerning the future public library in Swedish library press? -What characterizes the debate and why? Theories on political institutions and information society are used and the method is hermeneutic, a type of idea-analysis. The first step in the analysis consists of a categorized presentation of the material. The themes concern the form and content of the library as well as competence and hopes/fears.

The purpose of this Masters thesis is to investigate and describe the literary life of Madame de Staël, during the period of the French Revolution and the time shortly after. My intention is to do research on her impact and influence. I also want to examine her effect on Swedish literary society, with special references to Swedish authors. The method used is a qualitative one, where I have studied nonfiction and fiction connected with the field, for example Mme de Staëls own writings, which I make use of to illustrate the phenomena. During this period the society was dominated by patriarchical values and patterns of life.

The aim of this masters thesis is to examine the supply of magazines and periodicals for young people at the library. We also examine young peoples reading of magazines and periodicals and compare the librarys selection with what young people read. The main questions of this thesis are: What do young people do at the library on their spare time? What weekly magazines and periodicals do young people read? What range of magazines and periodicals do the city- and the school library have? Where is the department located and how is it designed? What kind of relationship is there between young peoples reading and the selection? To answer these questions we have done an interview with a librarian and a questionnaire among 13-16 year old children. We found that it is not often that young people read their magazines and periodicals at the library.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

The purpose of this Masters thesis is to make an outline of different methods and theories within the field of bibliometrics and critically review their strengths and weaknesses. The author studied literature that discussed bibliometric methods and theories. The number of empirical studies that are based on bibliometric methods and theories are numerous and where principally excluded, but some empirical studies were included as part of the argumentation for and against different methods and theories. The author first gives an outline of which methods and theories there are and describes their different strengths and weaknesses. Citation analysis has many different fields of application such as information retrieval, mapping science, evaluative studies and monitoring literature.

The aim of this Masters thesis is to examine librarians attitudes and values when it comes to the question if a new media, video games, should be introduced at the library or not. Video games are here seen as media primarily for youths. In our study we also wanted to study the discussions of quality and purchase, when computer games were introduced at the library. In order to answer our questions we conducted nine interviews with librarians working with children and youths, in eight libraries. By analysing their statements, using Maj Klassons theory where she defines the librarians role in three different strategies, we could demonstrate how the librarians reason when it comes to video and computer games, youths, quality and purchase.

The purpose of this Masters Thesis is to explore the process of selection that librarians face when selecting and acquiring cultural magazines to public libraries. The methods used are qualitative interviews and literary studies. A brief review is given of acquisition policies at public libraries and of cultural magazines and the important role they play in public libraries. Five interviews have been made at five public libraries to find out what factors affect the process of selection when it comes to cultural magazines. Two theories are used as a basis for the analysis of the result of the interviews and literary studies.

The purpose of this masters thesis is to examine how managers in public libraries are managing financial cuts. Questions posed are: What strategies are used by the library manager to handle the cuts and how are the strategies being worked out? What are the consequences of the cuts? How do the managers use their library plans in the work with the cuts and how do the plans change as a consequence of the cuts? Library managers in eleven communities are interviewed about their financial cuts in 2003 and/or 2004. The result shows that cuts are made in different ways. The study analysed the managers statements with a model about strategies created by Oulton.

The purpose of this Masters Thesis is to explore the impact of spare time reading fiction on the identity of teenage boys, and what it really means to them. To investigate this, we have focused our investigation on how teenage boys relate to and what they search for in their reading. The data collection is based on 8 interviews with boys in the age between 14 and 15 and on literature on the subject. The theoretical framework focuses on the reading theories of Joseph A. Appleyard, the transactional theory of Louise M.
