På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..

The purpose of this quantitative study has been to investigate teenager?s perception of obsessions and compulsive acts. Teenager?s perceptions and experiences as well as connections between the taboos surrounding the topic and the perception have been examined. The study has taken in to consider gender perspective, in regards to certain topics.

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.

The National Libraries task to save and preserve the national cultural heritage has turned to a new challenge in a digital world. The preservation of born-digital material for future use requires not only saving the digital object itself but also information about the object, preservation metadata. This is a relatively new issue and the library community has very little experience in this area. It has become evident that international cooperation is necessary to solve the task and that the development of international standards is of fundamental significance. This thesis investigates what has been done to meet the problems with the fast obsolescence of digital material with the focus on metadata.

The aim of this thesis is to explore and outline the cataloguing of sound recordings at two main Swedish audiovisual archives, The National Archive of Recorded Sound and Moving Images Statens ljud- och bildarkiv, SLBA and The Grammophone Record Archive of the Swedish Radio Sveriges Radios grammofonarkiv and its data base GAMBA. As non-book, non-printed, material in many ways differs from printed material, the institutions that deal with this kind of material have often developed their own rules for the cataloguing of it. The general codes for cataloguing, AACR2 and KRS, are insufficiently suited for audiovisual material. That is the reason why the IASA Cataloguing Rules, presented in this thesis, have been created. After the presentation of the IASA rules the problems of accounting for important sections of the catalogue record are discussed such as title, statement of respeonsbility, performers, physical description and notes.

This paper presents an investigation into the relationship between inmates and staff in a high security prison in Sweden. The primary objectives are to investigate this relationship from an inmate perspective and to identify key factors that may promote or hinder rehabilitative interaction with staff. Empirical data utilized in this study consist of semi-structured interviews carried out by the authors with nine inmates currently in custody of the treatment facility within the prison and six inmates housed within the study facility. This data collection method is an extension of grounded theory and four key themes were generated from the data analysis. The first of these examines the effect of rule enforcement on prison atmosphere and subsequent staff/inmate relations.

The purpose of this bachelor's thesis is to investigate how working librariansmanage controversial media. It builds on three debates in the media about libraries and booksthat have taken place during the years of 2012 and 2013. The questiones asked were: How dolibrarians manage racist media? How do librarians manage media that instructs on how tocommit crimes? How do librarians manage sexually explicit media? And lastly, how dolibrarians manage pressure from outside of the library? The theoretical framework consists ofRobert Hauptmans division of the two kinds of ethical strands of librarianship, in this thesiscalled ?Free information? and ?Information responsibly?. The method used to collectempirical material was qualitative interviews.

The thesis investigates how Uppsala University student nations steward their cultural heritage. The survey targets how student nations manage their cultural heritage, what financial priority they give it, their attitude towards it, and their awareness of it.A qualitative study of semi-structured interviews with representatives from 11 out of 13 student nations in Uppsala was implemented. The theoretical framework is based on the theory of David Lowenthal on the importance of cultural heritage, Susan Pearce?s theory on collecting, and Pierre Bourdieu?s theory on cultural capital. To investigate the importance of cultural objects theories by Ivo Maroevi?, Annette Weiner, and Igor Kopytoff was applied.The survey shows that stewardship of cultural heritage at Uppsala student nations is poor and in need of reform.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

The purpose of this paper is to investigate contents in the news in order to search for similarities between the two television news reports, Rapport and Nyheterna. The news features that I examined in my investigation were broadcast in April and May 2006.SVT and TV4 are two Television channels both belonging to the analogue television network in Sweden, which means that they reach out to almost the whole country. Hence I thought it was interesting to investigate their reports on similar news.The question:- Which are the similarities and differences between how the two programmes describe their reporting on similar news?When I put together the information from the two programmes in the schedule I based my analysis on the following questions: topic, place, length, type of reporting and per-sons/sources.The method for this investigation is a quantitative content analysis. However, some part of the collection of information and description/interpretation of the material is qualita-tive.Rapport and Nyheterna had an average of 15 similar news features per week, of which foreign news dominated.

ABSTRACTBackgroundPostpartum depression (PPD) occurs in 10% of women who have recently given birth. Postpartum depression is treatable but unidentified and untreated it could lead to serious consequences. There are multiple instruments for screening available. The Edinburgh Postnatal Depression Scale is the most frequently used and is regarded as the best instrument. AimThe aim of this study was to analyze to what extent and how midwifes and primary care nurses identify mothers with symptoms of depression respectively PPD.

An increasing number of scholarly publishers are beginning to make their journals available electronically. At the same time there is a growing amount of exclusively electronic journals freely accessible on the Internet. These are facts that librarians have to take into consideration.This master's thesis aims to describe the electronic journal and its role in Swedish academic libraries. In a review of current literature about electronic journals, the authors discuss their strengths and weaknesses, and their impact on scholars, publishers and libraries. To investigate the situation in Sweden, a questionnaire was sent out to 43 academic libraries.Questions were raised about the selection and acquisition of electronic journals, access, technology and economy.The results show that almost half of the 35 responding libraries offer electronic journals to their users.

This thesis describes the evaluation of a prototype (Illustrator) for future simulator training of Within Visual Range - combat in the Swedish Air Force. The main focus was to collect and transform user acceptance data (expert opinions) to useful guidelines for continued development. Thirteen active fighter pilots participated in the study. The aim was to use expert opinion to study a) the psychological user acceptance, and b) the technical user acceptance, of the Illustrator together with c) gathering opinions for future improvement. Three psychological aspects were rated before and after the sessions to measure psychological user acceptance.

User-centred acquisitions at three academic librariesA new way of developing collections has been adopted at a number of small academic libraries, user-centred acquisitions. The method implies that the main way of building the collection is by means of receiving suggestions of titles from library users. The main purpose of this thesis is to investigate changes in acquisitions of monographs. At a more detailed level it seeks a deeper understanding of what user-centred acquisitions is and how the method effects the acquisitions process. Changes in stock management and the reason why the libraries have chosen the method is investigated as well.

The number of female officers employed in the Armed Forces is low. Of the total proportion officers, female stand for 4.8 %. The Armed Forces are currently working actively to level out the distribution. This paper is intended to create a better understanding of the slow increase in female officers in the Swedish Armed Forces. The study is qualitative and the results from the data collection have been based partly on a text analysis, partly on a theme-based group interview in which three themes have been discussed.
