In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.

The purpose of this Master?s thesis is to study the organisational culture of two public libraries managed differently. One of the libraries in my study is run by the local bookstore and the other is run by a staff co-operative. My aim is to elucidate characteristic features in the culture of these two public library organisations. The questions I posed are which types of organisation culture can be identified in the two given examples and what the factors are that may be of importance for these cultures.

The purpose of this thesis is to examine the debate in library journals and in official reports on the subject of library education in Sweden. We focus on two periods: the period just before the year 1972 ? when the library education was transformed into being occupationally-oriented and the period just before the year 1993, when the library education was transformed into being ?academised?. This Master?s thesis shows that the debate and the arguments among initiated people in the library world have had some impact on how the library education was transformed later on.

When producing an interview report the researcher is put to the test of describing the qualitative interview method in terms of assumed orderly steps and procedures taken during the interview process, while at the same time account for a very social dynamic process. In practice, even the most carefully prepared scenario for a qualitative interview study probably does not correspond to the expectations made. What happens between the plans and the actual interview itself? This issue is investigated by contrasting the actual engagement of the participants in an interview project to how these relationships are accounted for in Master thesis from the Swedish School of Library- and Information Science in Borås. Theory and methodology from Actor Network Theory (ANT) have been applied into the area of qualitative interviews.

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 Master?s thesis is to study an electronic reference service from a user perspective. By qualitative interviews with eight students the thesis examines their information behaviour, why and when they use the service, the user?s experiences of the service and the communication with the librarian. The users have all used the Swedish electronic reference service Fråga biblioteket ? Forskningsbibliotek.

This Master?s thesis will try to describe the beginning and development towards a modern public library of the town library in Karlskrona between 1906 and 1959. The specific years refers to the year the library was established and the year it moved to the new library building in the centre of Karlskrona. The aim of the thesis has been to do this historical description and to look at the course from the perspective of the national policies and development for the Swedish modern public library. The thesis is based mainly on reports of the proceedings of the public library and other biographical documents and literature, which has been found in two local archives.

This Master?s thesis aims to map and analyse publishing patterns at two academic departments at the University of Gothenburg - the department of Physics and the department of History. The investigation has been guided by a set of questions: Who chooses to publish their scientific outcomes? In which forums do they publish findings? In what kind of media are the results published? What type of findings get to be published? The departments' publication lists have been examined, covering the years 2004-2007. Furthermore, ten scientists have been asked to describe factors contributing to their individual publishing pattern.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

The purpose of this Master's thesis is to examine whether a web-based library catalogue is to be considered user-friendly. We have examined this from a user-perspective by interviewing users of a web-based catalogue at a public library. In order to get a picture of the user-friendliness of a catalogue, the thesis is centred upon the following questions: How is a web-based catalogue used? What problems do the users experience? How is the catalogue perceived by its users? Since the producers of these catalogues now are taking into account the research upon human-computer interaction, we are also interested in finding out whether a web-based catalogue is more user-friendly than a more traditional OPAC. We do this by comparing the results of our examination with earlier studies of OPAC use.

This report describes the design and implementation of a multi-Master, packet based protocol for small and tiny microcontrollers where resources are limited. The protocol was named "Tiny Controller Network" or TCN for short. The protocol is meant mainly as a control bus for automation and sensor acquisition applications but due to its flexibility can also be used for other purposes as well. It borrows some of its functionality and design ideas from the well known CAN bus and Modbus but also has a number of major differences like the use of standard hardware and time synchronisation. One of the key aspects during the design was the use of very little system resources and common on-chip hardware peripherals like a UART.

The purpose of this Master?s thesis is to examine how some university students, who are using the libraries extensively, use and experience the public and the university library and what they expect from the two different library types. I also compare their expectations with the different tasks and aims of the two library types. To answer this I have interviewed seven students at the department of history of literature at Göteborg University. I have also studied some literature and research related to this subject, for example user studies about students and libraries and the information behaviour of distance students.

The aim of this Master thesis is to study electronic publishing, and our main purpose is to examine different strategies of publishing such as: markup languages and page description formats. We examine in what context these strategies are used for publishing, when it comes to scholarly documents produced by Swedish universities and university colleges during the spring of 2002. We apply a sociological perspective as the theoretical framework for to identify the main purposes for scientists to publish their work. We also discuss properties belonging to the different formats: XML, HTML, PDF and PostScript. By doing a content based survey of the websites at Borås University College and at Gothenburg University, we have found that the most common form of electronic publishing, regarding scholarly documents, are lists with bibliographical information on publications and presentations of current research.

The main purpose of this Master thesis is to illuminate the understanding of local politicians regarding the public libraries and the librarians. We argue that the local politicians´ opinions regarding public libraries and librarians influence the way they act and react in their roles as politicians.In order to achieve the aim of this thesis we focused on following questions:What are the opinions of the politicians:- regarding themselves in relation to the public library?- concerning public libraries in general and its functions especially in the municipalities of their own?- concerning the librarians and their work in a public function?What are the conclusions to be drawn regarding the politicians´ interest and commitment to public libraries in the politic daily-life of the municipalities? Our empiric material consists of qualitative interviews with six politicians elected in two municipalities in the interior of Västerbotten, a northern sparsely populated district. In order to distinguish the various opinions that emerge from the material, we apply a phenomenographic approach. The analysis result we present in three conceivable categories in order to express the different opinions.In general our study points at a positive and favourable attitude to the public library, and all the respondents assume that the municipality ought to offer this service.

This Master's thesis aims to study the relationship between two publiclibraries and Berättarministeriet, a foundation that offers free writingworkshops for children in areas with high levels of unemployment. Theworkshops are located in spaces that formerly belonged to the libraries.Questions posed in this thesis are How can the relationship between thelibraries and Berättarministeriet be described?, Why did the relationship turnout differently in the two places? and How does the library see itself, inrelation to Berättarministeriet?The theories used are Ögland's taxonomy for relationships between librariesand local organizations, and Folkesson's theory on interaction betweendifferent professional groups, and this was studied through interviews. Theresults showed a relationship without much interaction, beyond a "handover"of children from one place to the other, with time and shortness of staff beingcontributing factors to the low level of collaboration. Regarding the differentrelationships in the two places the results were not conclusive, butnevertheless showed tendancies of issues in the legitimacy dimension, fromthe library towards Berättarministeriet.
