Konstruktion och utprovning av monteringsverktyg för motorfäste- och lyftörebussningar till TEC V2500 : Volvo Aero Corporation, avd 9856
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.
Identitetssökandet hos unga flickor i 2010 års barn- och ungdomslitteratur
My ambition with his exam is to study how young girls are being depicted in swedish novels of 2010. I have analyzed how the identity and the search for identity are produced in these books. To be able to make my analysis of these books I have used Maria Nikolajeva?s book Barnbokens byggklossar. From wich I have worked out a few questions that I have used my analysis in the portrayal of these girls.
Högskolebibliotekariers informationssökning ? En studie i hur högskolebibliotekarier söker information till sig själva och för andra
The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.

Kontinuerlig RFID-detektering för batteridrivna system
This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.

Lokal sökalgoritm för initiering av den genetiska populationen i ett praktiskt "vehicle routing"-problem.
Befintliga studier har påvisat att genetiska algoritmer presterar bättre om de ges en bra startpopulation. I denna rapport presenteras en lokal sökalgoritm för att skapa en population med fokus på ?vehicle routing?-problem. Algoritmen använder sig av heuristik i en blandning av simulated annealing och tabu search för att skapa individerna till populationen. Utvärderingar av algoritmen på ett praktiskt problem visar att den ger en bra start jämfört med en slumpmässig startpopulation, vilket är vanligt att använda.
Den svenska arbetslöshetsförsäkringens effekter på långtidsarbetslösheten
This is an examination of the Swedish unemployment insurance system and the effects it has on the Swedish long-term unemployment. A search model is explained to give an understanding to the incentives of the unemployed. Different mechanisms that create unemployment and that could create long-term unemployment are investigated, but primarily the unemployment insurance is in focus.The Swedish unemployment insurance has undergone several changes the last fifteen years that have improved its efficiency. The introduction of a finite duration of unemployment insurance entitlement was an important step and so was the decrease in the replacement ratio. Even so, I assess that there is still room for improvements of the incentives to search for work among the unemployed.

Kontrollerad vokabulär eller naturligt språk? En empirisk studie.
The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.

Återvinning av skönlitteratur - Återvinningsverktygens anpassning efter användares sökbeteenden : En fallstudie på Trelleborgs bibliotek
Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.
Vägen till god användbarhet : En fallstudie inom informationsarkitektur med fokus på ett informations- och filhanteringssystem
Since Internet has become a more important and more certain source of information the user require greater and more demands than ever before on the layout and function of different web pages. When Search engines gives us the opportunity to millions of hits in just a fraction of a second it?s essential to optimize the structure and architecture, which forms the foundations of all the content. In a time when a company?s digital footprint plays an important role for the costumer and the transmitter it?s of utmost importance to have a steady, well-structured foundation to build new platforms of information on.But how do you manage to build a good foundation? Some of the most important key elements in Information architecture are Organizing, Navigation, Search and Labeling.The aim of this study was to create guidelines for a user-friendlier interface, by analyzing the principals and gathered data.
Bibliotek och intranät ? en fallstudie av intranätanvändandet i en biblioteksorganisation
This master?s thesis seeks to examine how a public library use the intranet with regards to the possibilities that today?s intranet technology offer ? especially concerning functionalities that support information, communication and knowledge exchange in the organization. The purpose of the study is to investigate how employees in one specific public library perceive and use the intranet in their daily work. The theoretical framework takes its point of departure in two complementing models regarding the implementation, development and management of intranets and a model of a multi perspective view of the intranet as a shared information space for content, communication and collaboration. The study is based on interviews with eleven of the intranet users, whom with the aid of an interview guide have been asked questions regarding goals, implementation, content, design, applications and advantages/disadvantages with the intranet.
