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.

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.

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.

The purpose of this study was to investigate young teenagers 13-16 reading habits and attitudes concerning todays modern teenage literature especially written for the young teenagers. 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.

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.

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.

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.

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.

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..

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.

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.

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.

Syftet med denna studie är att studera några utvalda lärares syn på individualise­ring i matematikundervisningen för årskurs 4-6. Denna studie belyser och analyserar hur lärarna i studien ser på individualisering och vilka möjligheter och begränsningar de upplever, vad lärare grundar sin individuali­sering på och hur de sedan planerar och anpassar den i sin matematikunder­visning. Med hjälp av en urvalsenkät, där lärare svarade kortfattat på ett fåtal frågor angående deras individualisering i matematikundervisning, valdes lärare ut till sex olika kvalitativa intervjuer. De kvalitativa intervjuerna genomfördes för att få en djupare förståelse för lärares syn, förhållningssätt, målsättningar och planeringar med individualisering. De intervjuade lärarna har alla en god medvetenhet om individualisering och genomför den framförallt genom olika arbetsmoment och arbetsmaterial i sin undervisning.

The purpose of this study was to investigate the effects ofparticipation in an integrated intensive stuttering program (IST) on stutteringbehavior, intelligibility and communication attitude, at individual and grouplevels. Five children aged eight to twelve years participated in the study.Stuttering behavior and intelligibility were judged by two independentstudents in speech and language pathology based on a total of eight videorecordings, before, during and after therapy. Communication attitude wasmeasured by the Swedish version of the self-report questionnaireCommunication Attitude Test (CAT-S). At an individual level, the initialstuttering profile and the changes shown during and after the IST varied. Ata group level, a significant decrease in stuttering frequency and asignificantly higher level of intelligibility were found, after as compared tobefore therapy.

The aim of the study was to explore how persons with aphasiaexperience literacy and reading and writing. Seven persons with mild-moderateaphasia were interviewed. The interviews were recorded, transcribed andanalysed using qualitative content analysis. The analysis resulted in three mainthemes; A changed reading, A changed writing and How to adjust andaccommodate to new conditions. The most apparent aspect was that theinformants experienced that literacy had changed, regarding what and how theyread/write.
