Trough a literature study based on both philosophic and objective fact this essay is taking off in the meaning of public space. It investigates how the information society and its virtual world are affecting the idea and use of public space in the city. The city and the actual world have developed from the traditional meeting between people while the virtual world is based on flows of information. The information flow has expanded through the Information and Communication Technique (ICT). ICT covers among others Internet, mobile phones and computers.

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The main focal point of this study is about public libraries and its possible roles in today's society. Going from having had a clear educational orientation, public libraries has with time amassed several other roles, which all need to relate to the swedish law regarding libraries and other governing documents, as well as business plans. This thesis focus on a qualitative investigation, which was conducted through in-depth interviews with librarians and other staff at a public library in Stockholm, named bibliotek Plattan, to ascertain the prevailing opinions within this facility about the role of libraries and librarians. The choice of examine this particular library was based on the fact that bibliotek Plattan differs from the public library in general and only offers material for adults. Their collection of litterature is primarily based on fiction novels.

The writing style of a particular author can be divided into many subfeatures, for example use of words, language and syntax. Focusing on the latter, this study aims to show how well syntactic information alone can attribute the correct author to a document. Syntactic information is defined as overlapping syntactic subtrees of height one (1) for all sentences of all included documents. The performance is compared to that of the previously very successful method of comparing stop word frequencies. These are words normally excluded from search engine queries, because they are present in all sorts of texts regardless of topic.

This study aimed to investigate whether there was a correlation between an individual?s selfesteem and search for confirmation on social media. The study also sought to answer whether there were differences in self-esteem and search for confirmation from a gender perspective. In this study social media was defined as Instagram. The choice was founded on the basis that Instagram in the current situation is one of the world's largest social media that allows users to share their everydaylife in pictures, which are commented and ?liked? by other users.

   To work and live in the same place where ones employer also is the landlord, can create a situation with many special requirements for the individual. Constrains regarding time, space and impact on social life is likely to appear. Based on theory and empirical research about the Boundaryless work and the Psychological contract the purpose of this report is to examine employees who live and work at the same place. This is done by studying the regulation regarding time and space factors and the psychological contracts in expectations and in violation of the psychological contract and the risks associated with this like Locked-in factors. The study includes interviews with managers and employees (n=9).

Mind the gap encourages you to beware of the interspaces. The project seeks to defend the gaps that occur in time and space and encourages the reader to care about the interruptions of the routine-like and planned, whilst also opening up a discussion about interaction and participation. Mind the gap is a project about the many opportunities the public space has in the contemporary city. What you have in front of you is the result of this project. As society constantly changes, new and different needs arise in the city and it is necessary that architects and planners understand and adapt to these changes. They have to be able to develop new ways of thinking and to challenge established perceptions of what the public space is and should be. This means being able to see that the public space could be different and to recognize the potentials for it to change. This project examines the underlying ideals of urbanism and investigates the potentials of the City when shaped by these ideals.

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.

The purpose of this thesis is to evaluate two pearl growing methods in ISI Web of Science. The methods tested are Find Related Records FRR, an automatic service that uses bibliographic coupling, and Author Keywords AK, where searches are performed using the two first keywords from this field. Both search methods were used on twenty initial documents and the first twenty hits were evaluated for relevance using a binary scale 0,1. The relevance criteria were based on specific information needs connected to every initial document. The measures used to evaluate the effectiveness of the search methods were Precision at DCV=10, P10, and Uninterpolated Average Precision AP.

I examine how relationships between people and objects are created and continues through contiguity every time one use or touch an object and through participation through use and memories. The aim is to continue a relationship and to keep a communication alive with people beyond time and space, then, now and henceforth. I take advantage of and transform the traces in an object that belonged to someone. Parallel I create new space for bodies to put their mark for the first time. I compare my work with the Nordic Museum's task to preserve the present for the future.

The purpose of this study is to examine whether the high school textbook on religious studies differences in how Christian ethics and in what way it is presented in comparison with the presentation of Buddhism, Hinduism and Judaism and it´s ethics. The analyzed material is textbooks from the late 1960s to the 2010s. Due to the survey´s nature the focus is first and foremost the chapters dealing with religious ethical issues and what amount of pages or space the different religions are given in the books. The results from the textbooks are compared with the curriculum that is or was effective during the time the books were published. This is done to determine whether there is a clear link between the books and the guidelines of the curriculum.

This two years master?s thesis takes interest in the concept of marketing related to the Children?s Library. The purposes have been to investigate the perception of marketing among a few librarians working at the Children?s Library in the Swedish region of Halland and further to analyse their perception of marketing in the daily work at the library. Eventually to analyse the consequences of these librarians approach to marketing related to their perception of the library?s mission.

The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
