The aim of this thesis is to describe passage retrieval (PR), with basis in results from various empirical experiments, and to critically investigate different approaches in PR. The main questions to be answered in the thesis are: (1) What characterizes PR? (2) What approaches have been proposed? (3) How well do the approaches work in experimental information retrieval (IR)? PR is a research topic in information retrieval, which instead of retrieving the fulltext of documents, that can lead to information overload for the user, tries to retrieve the most relevant passages in the documents. This technique was investigated studying a number of central articles in the research field. PR can be divided into three different types of approaches based on the segmentation of the documents.

Det har funnits en speciell mytisk bild av den fornskandinaviska mytologin sedan romantikens fantasifulla epok. Det ges ofta en bild som beskriver gudar och människors samspel på ett lekfullt sätt. Schamanismen har med sin annorlunda världsbild stått för något exotiskt men samtidigt skrämmande. I uppsatsen ges en beskrivning av fornskandinavisk sejd och samisk schamanism och en jämförelse mellan dessas likheter och skillnader. Genom att söka svar i både den poetiska och prosaiska Eddan, samt Heimskringla söker författaren komponenter för att beskriva det magiska fenomenet sejd.

In motorsports competition, safety reasons require that the vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the vehicle body deformation. The roll cage also works to protect the vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

The swedish law of contract is fundamental within several civil law areas, among others labour law. The labour law contains more explicit legislation specificly adapted to the relation between employers and employees. Sometimes the labour law needs to rely on more general regulations, such as the law of contract. When the situation contains a specific contract relation dilemma it is logical to use the law of contract, when for example the law of employee protection does not reach an acceptabel solution.Transfer of undertaking is a situation were the employee protection is disregarded. The Euro directive 2001/23/EG prescribes, by its implemented rules in the law of employee protection, that rights and duties, such as employement agreements, passes on to the earner of the business.

The primary aim of this thesis is to examine female lawyers' relationships to information from different angles. The starting-point is that the legal information, retrieved from through different information sources, is not free from values and subjectivity. The commonly presumed objectivity of legal information is questioned, based on the fact that this kind of information has developed and changed historically in the context of, and in relation to, society. Another aim is to find out how the female lawyers experience their situation in a traditionally masculine working environment. Qualitative interviews have been carried out with seven female lawyers involving questions about their daily work about the sources that they are using.

Bakgrund och problem: Goodwill har sedan lång tid tillbaka varit ett omdiskuterat ämne ochreglerna gällande redovisningen ändrades avsevärt i och med ikraftträdandet av IFRSreglerna.Tidigare var företag tvungna att göra årliga avskrivningar men numera skagoodwillposten istället prövas för nedskrivning minst en gång per år. Det framgår tydligt attgoodwill är en post som det är mycket svårt att bestämma värdet på, vilket resulterar i ett stortutrymme för subjektiva bedömningar. I många resekoncerner utgör goodwill en betydandepost och de antaganden som ligger till grund för bedömningar av värdet får därför storbetydelse för om en nedskrivning krävs eller ej. Detta har lett fram till följande frågeställning:Hur genomförs nedskrivningsprövningen av goodwill inom utvalda resekoncerner och vilkenär den tillhörande problematiken?Syfte: Syftet är att utreda hur utvalda resekoncerner går tillväga vid en nedskrivningsprövningav goodwill samt vilken eventuell problematik som uppstår.

Det avfall som kommer från gruvbrytningsprocesserna benämns anrikningssand och kan innehålla miljöfientliga ämnen. Det innebär att anrikningssanden måste omhändertas under säkra förhål-landen. Generellt använder Svenska gruvor naturlig topografi och/eller fyllningsdammar för att omringa anrikningssanden, även vid Aitikgruvan. Fyllningsdammarna är uppbyggda med en startdamm av morän och har därefter utökats med mer genomsläppligt tillgängligt material med både nedströms- och uppströmsmetoden. Höjningar av dammarna sker kontinuerligt eftersom gruvans produktion pågår och ger även behov av framtida prognoser för att säkerställa dammarnas stabilitet i framtiden.

Organizations that want to maintain a good innovation capability can seek knowledge both within and outside its boundaries. Opening up innovation processes, through so-called open innovation, allows organizations to combine internal and external knowledge sources in order to include previously excluded perspectives to the innovation process. This study examines how knowledge is created and transferred when conducting open innovation through crowdsourcing. It is done based on Nonaka?s (1991; 1994) theory of how knowledge is created through conversion processes, where implicit knowledge can be converted into explicit knowledge and vice versa.

Today we are living in a knowledge-society where knowledge sharing is of utmost importance for companies in order to keep their competitiveness. Therefore, it is a much debated issue - in both the academic and the corporate world - in what way one should handle the knowledge which continuously is created within companies. The aim of this study is to describe how practitioners share tacit knowledge within a large knowledge company. By that we aim to get an answer to how the chosen theoretical models regarding tacit knowledge relate to the empirical world. In this study we will focus on tacit knowledge in contrast to explicit one.

The goal of this master thesis is to show the benefit of using computer games of the type First Person Shooter, FPS in the field of military simulations. The main focus in this is around a couple of topics. Creating the AI that controls the behaviour of the computer-controlled characters, the bots. Create an environment where it is possible to supervise the bots and also design a framework that enables cooperation between a group of bots, a squad. The result is Total Unreal Studio, TUS, a program where it is possible to add bots to a squad, connect them to a game server and inspect what the bots are doing.

Previous research within the subjectwill also be presented.Empirical foundation: The empirical foundation consists of three conducted interviews anddata collected from the chosen PE-firms as well as six different holding companies.Conclusions: The governance mechanisms used in the PE-firms we have chosen are stronglyrelated to both theories within corporate governance as well as previous research on thesubject. The governance mechanisms being used are an explicit owners agenda and strategy, athorough acquisition process, usage of external competence, active ownership through theboard of directors and the insertion of incentive systems..

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Having an intranet as a source for information and communication is common in most contemporary organizations. Research shows that the intranet in itself does not have an explicit area of use, and that leaves every organization to make decisions of the associated functionality on their own. At the same time the strategic opportunities that the intranet could bring get lost somewhere along the way. This means that problems regarding the strategic use of an intranet becomes apparent and may result in loss of investments for the organization. The purpose of this thesis is to identify central choices that can be used as points of discussion and help organizations to work with their intranets on a more strategic level.

It is important that the language in textbooks for foreign language learners reflects the language that the learners would encounter in real life. For this reason, the presence of the thousand most common nouns in two Swedish textbooks in Spanish for upper secondary school is observed in this study. Furthermore, this study aims to examine how these nouns occur in order to determine if their pattern of occurence favours the learning and consolidation of words. The main materials that have been used are A Frequency Dictionary of Spanish by Davies (2006) and the word search program available in the digital versions of the textbooks. The results show that the presence of the thousand most common Spanish nouns does reflect the frequency information presented in the frequency dictionary but not all thousand nouns are included.
