Ämnesordsindexering av ryttmästare John Andréns specialsamling : Utveckling av en indexeringsmodell utifrån teoretiska och praktiska perspektiv
This is an explorative study about subject indexing of a special collection of books, administered by the John Andrén Foundation at the library of Ystad. The study summarises a number of theoretical perspectives as well as some practical instructions on how to carry out the task. Theories have been placed into five different groups according to their various approaches to subject indexing. These have been analysed in regard to their usefulness to the Andrén collection. The authors have tested and evaluated six practical models on a selection of books from the Andrén collection.
Musikbranschen : Från demo till upplevelse
Purpose: The purpose of this study has been to identify different actors and processes in music recording. We find this interesting since there have been a lot of changes in the music industry over the last years. Our ambition has been to point out different actors and their roles during the advent of recorded music, and identify different features and processes in the creation of music today and in the future. To fulfill our purpose we have had the following research question: What characterize, in a future perspective, the gathered process during the creation of recorded music from idea to delivery and experience?Method: We have used a qualitative approach for this study and we have conducted seven interviews with persons from different areas of the Music Industry and radio.
Kvalitetssäkring
This thesis has been made in cooperation with Forsheda Stålverktyg AB which develops and manufactures injection moulds and diecasting tools. The main concern has been their Trading-system which provides them with considerable amount of quality lost function.Focus has to however be put on the analysis of the Trading-system due to the fact that this has previously meant various quality issues for the company.This thesis treats quality assurance of the Trading-system, identification of the problems in the process and improvements of these problems.Quality assurance is carried out when a company detects that their quality based costs become too high. Quality based cost are? the costs that would disappear if a company's products and its different operational processes were absolute? (Sörqvist, 2001 p.30, free translation from Swedish). High quality based costs often result in increased quality problems, which can lead to substantial economic loss for the company.This work has resulted in a thorough review of the Trading-system whereupon problems have been identified.
EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.
Flerspråkiga Tesaurer: Att uttrycka ett och samma begrepp utifrån skilda kulturer och olika språk.
The aim of this paper is to investigate the problems in multilingual thesauri, with a focus on the problem of conceptual equivalence between different languages. This study compares the problems and solutions that have been carried out in the Eurovoc multilingual thesaurus with the ISO 5964 ISO 5964 is a guideline for establishment and development of multilingual thesauri. The Swedish descriptors in the subject area "education and communication", from Eurovoc have been observed and compared with the guidelines recommendations. The results show that, the majority of the investigated Swedish descriptors do not present any problem. Most of the terms that are used as descriptors are found in dictionaries and glossaries or appear with high frequency in Swedish websites.
När pojkar betraktas som män : en kvantitativ och kvalitativ studie om åldersgräns för tonårspojkar på Sveriges kvinnojourer
This paper aimed to investigate to what extent there is an age cut-off for teenage boys in the women?s shelters of Sweden and how a possible cut-off is described and maintained. This occurrence has not been investigated earlier to a large extent, which emphasizes the importance of this paper. A mixed strategy was used to cover both the frequency as well as the explanations to the age cut-off. The quantitative survey was sent to all women?s shelters in Sweden and the result showed that 56 % of the shelters had an age cut-off for teenage boys from 12 years of age and above.
Vilken ställning har dagens ungdomsbok? En studie om hur dagens ungdomslitteratur bemöts av sin målgrupp

The study also includes the readers apprehension of the literature and how the target group is reached. The study is based on results from questionnaires, interviews and by compiling summaries of literature relevant to this study. Earlier research has been compared with results from this study. Reflections made by teachers and librarians concerning the youths reading habits are an integral part of the study.
Operationell risk i banker: Hantering och offentliggörande av operationell risk ? En studie av skandinaviska banker
Starting in January 2007, capital adequacy of internationally active banks will be regulated by the new Basel Capital Accord, International Convergence of Capital Measurement and Capital Standards ? a revised framework, [Basel II]. The framework introduces for the first time minimum capital requirements for operational risk and encourages market discipline of capital adequacy by initiating requirements for public disclosure of quantitative and qualitative information on operational risk exposure. This thesis examines the nature, definition, management and public disclosure of operational risk in Scandinavian banks based on regulations and recommendations presented in Basel II. We find that the models currently available for addition of operational risk to the capital requirement do not reflect actual operational risk exposure of banks.
Föreställningar om etnicitet som orsak till politiskt våld - ett antropologiskt perspektiv. En diskursanalys av artiklar i svensk dagspress om kriget i forna Jugoslavien 1991-1995
The aim of the thesis is to examine discourses about political violence categorised as ?ethnic? in academic literature and the media. Employing the method of discourse analysis, the study analyses news coverage of the wars in former Yugoslavia 1991-1995. The theory applied is based on Michel Foucault?s theory of the relationship between power and discourse in the constitution of knowledge, and the main arguments are supported by the work of the political scientist V.
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
AIS-vektorer i antikollision - En relativ sanning
Intervjuer med kunniga på AIS-området har utförts parallellt med en enkät riktad till aktiva befäl ute till sjöss. Detta i syfte att ta reda på dels hur detta hjälpmedel bör användas vad avser antikollision, dels hur det faktiskt används i praktiken.AIS, Automatic Identification System, är ett informationsdelningssystem som hjälper fartyg att navigera säkert genom att sända ut egen navigationsdata och samtidigt ta emot motsvarande information från andra fartyg. Systemet nyttjas även som informationssystem för landbaserade stationer såsom VTS-centraler och kustbevakning.Undersökningen har engagerat och visat att expertisen anser att AIS, i många avseenden, är ett bra och användbart hjälpmedel som bör komplettera övrig utrustning vid bedömning om kollisionsrisk. Vidare visar enkäten att ARPA-systemet, trots vissa inneboende brister, tillmäts större förtroende än AIS och AIS-vektorer används därför sparsamt. Enkäten visar även att en stor del av de aktiva inte är främmande för att göra avsteg från sjövägsreglerna emedan expertisen i huvudsak avråder från sådant..
Electronic Journals, Just in Case, Just in Time, Just for You ? användning av elektroniska tidskrifter vid Chalmers tekniska högskola
This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.
Vox pop, enkät och fem funderar. : En kvantitativ innehållsanalys av enkäter i tre svenska dagstidningar åren 1997 och 2007.
The purpose of this BA-thesis was to study how three daily Swedish newspapers use a specific type of exemplars, which are recognized by a number of attributes. A photograph of the person that is interviewed always illustrates this type of exemplars and at least two persons are asked the same question. The three newspapers that have been compared in this study each represent one of the major types of Swedish newspapers: morning press, tabloids and local press. By using a quantitative content analysis, one month was examined in all three newspapers in the year of 1997 and 2007. Two of the theories that have been central in the thesis are Colin Sparks model of tabloidization, which demonstrates the process of tabloidization and McQuail?s description of commercialization.
Skapandet av varaktiga relationer vid mötet mellan byggbranschen och "den nya ekonomin": en fallstudie av relationen mellan NCC Telecom och Ericsson Radio Systems
Uppsatsen handlar om skapandet av varaktiga relationer i byggbranschen. Undersökningen genomfördes som en fallstudie av relationen mellan NCC och Ericsson avseende 3G-utbyggnaden. Syftet med uppsatsen är att undersöka orsakerna till aktörernas samarbetssvårigheter i byggbranschen, när det är lämpligt med varaktiga relationer, hur sådana skapas samt vilken samarbetsform som är lämplig. Aktörernas samarbetssvårigheter beror på de traditionella avtalsformerna, som endast avser enskilda projekt. För att främja samarbete måste parterna skriva långsiktiga avtal så att varaktiga relationer möjliggörs.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
