Ämnesindexering av spelfilm
The aim of this thesis is to examine possibilities concerning subject access to fiction film, i.e. appropriate ways to describe fiction film for subject retrieval. Problems regarding subject indexing in general, and subject indexing of fiction film in particular, are identified, as well as the uniqueness of fiction film and film genres. Four types of subject aspects are discussed: form and genre, fictitious characters, setting, and general topics. Several guidelines, form- and genre lists, and subject headings lists are examined and treated as potential indexing tools.

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Implementering av ett verktyg för dokumentering av riskanalyser
För att en maskin ska anses som säker för användning krävs det att den uppfyller maskindirektivet. Maskindirektivet är väldigt generellt och kortfattat. Därför finns det standarder som förklarar mer specifikt maskindirektivets olika delar. Uppfylls inte standarderna så uppfylls inte maskindirektivet för respektive område och därmed är maskinen inte redo för användning.Examensarbetet har utförts på Rapid Granulator AB. Företaget är idag en av världens största producenter av granuleringskvarnar.
What factors correlates with the use of game meat, wild fish, berries and mushroom in Swedish households : urban vs. rural areas
This study was made to see too what extent Swedes uses consumptive resources such as berries and mushrooms, game meat and meat from fish in their household on a yearly basis. I have also looked into the difference between rural and urban areas in Sweden. Further aim was to determine what factors that correlates with the participation in berry and mushroom picking and the use of game and fish meat within the household. The study was conducted in form of a mail survey that was sent to randomly chosen persons in every municipality in the six northern most counties in Sweden and in the county of Stockholm. In addition a sample was sent to randomly chosen persons on a national level.The results showed there is a difference in use between rural and urban areas in Sweden in all 4 investigated consumptive resources.
Fotots väg från arkivboxen till allmänheten : En dokumentation av DiBiS digitaliseringsprocess samt en studie av digitaliseringens följder
The purpose of my one year master?s thesis is to add a documentation of a data processing-process of photo- graphs to the administration of archives. The thesis is written from an archival science perspective which is to be seen in my choice of literature, method and questions at issue. To be able to form a documentation of a data processing-process I studied DiBiS, a company specialized in digitalizing old photographs and publish them on a online database. I also added a chapter where I studied how archival institutions used to handle their old photo- graphs in a traditional manner so the reader of this thesis will be able to understand and see the differences be- tween traditional and modern photograph management.
Differentieringen av det generella strandskyddet : attitydundersökning i Gagnefs kommun och Bergs kommun
Uppsatsens syfte är att undersöka hur Gagnefs kommun och Bergs kommun arbetar med det generella strandskyddet, vilka attityder till detta som finns i kommunerna och hur arbetet påverkar landsbygdsutvecklingen.
Särskilt fokus läggs på hanteringen av små sjöar och vattendrag.
Undersökningen har skett med hjälp av en kvalitativ metod
som innefattar intervjuer med markägare och tjänstemän från kommunerna samt observationer.
Analysen utgår från Garrett Hardins begrepp tragedy of the commons, Elinor Ostroms begrepp common-pool resources och open access resources samt Bo Rothsteins begrepp sociala fällor och tillit.
Slutsatsen med uppsatsen är att Gagnefs kommun och Bergs kommuner arbetar olika med strandskyddet gällande små sjöar och vattendrag.
En majoritet av informanterna anser att det generella strandskyddet endast ska omfatta naturliga vattendrag, samt att strandskyddet bör vara mer flexibelt på landsbygden än i storstäderna. Flexibiliteten innebär exempelvis att strandskyddets regelverk ska anpassas till platsen och inte tillämpas generellt över hela landet..
Rekommendationssystem för interaktiva musiktjänster : en utredning av aktuella trender och attityder gentemot framtidens rekommendationssystem diskuterat ur forskar-, industri- & användarperspektiv
Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.
Databashanterare i Visual C++ för flygradiostationer
Examensarbetet som är utfört för SAS Flight Academy innebär att modernisera
hanteringen av flygradiostationer
för en flygsimulator från 1968. Detta görs med hjälp en PC som kopplas till det
nuvarande datorsystemet med ett
parallellkort. I PC:n finns en Microsoft Access databas där all data lagras om
världens alla flygradiostationer.
Informationen om flygradiostationerna finns lagrade på en CD-ROM som
uppdateras ett antal gånger per år.
Klienten till databasen är programmerad i Visual C++ och använder Microsofts
programbibliotek MFC för hantering
av databasen. Klienten har två uppgifter dels sköta hanteringen och dels
uppdateringar av databasen.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods
for estimation of the down channel (base station to mobile subscriber) in
Wide-band Code Division Multiple Access (WCDMA).
The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is
a conventional method that bases the estimates on data that is known to both
sender and receiver, so called pilots. The second method, Decision Directed
Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data
for estimation.
Simulations show that DDCE, in comparison to OFCE, does not attain an
improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An
improvement is only seen when the BER becomes much lower than what is common in
real situations.
In conclusion DDCE is complicated, involves many mathematical operations and
gives insignificant improvement of SNR when BER takes common values. It is
legitimate to question if it is possible to use the method in a real mobile
phone system..
Näthat : I gråzonen mellan straffrättsligt ansvar och yttrandefriheten
The following thesis concerns the conceptualization of openness within the open access movement. Open accesscan be understood as a phenomenon or a movement that aims at changing the current system of scholarly communication.Consequentially, the movements goals arose in relation to the escalating serials crisis in scholarly communicationand the increasing power of commercial publishers. The purpose of the thesis is to study three centralopen access declarations with the aim of uncovering the different conceptualizations of openness found withinthese texts. Leaning on the theoretical position known as actor-network theory, the declarations role within a surroundingnetwork is explored by focusing on how openness as a concept has been produced and reproduced bycentral actors. Two overarching questions frames the study: How is openness conceptualized within the declarations?And how can openness, as a concept, be understood as an effect generated by a larger network?The first part of the study focuses on the first question.
Vad har svenska företag för syn på sovande data och hur hanterar svenska företag sovande data med avseende på identifiering och lagring?
Alltför många organisationer har datalager innehållande stora mängder sovande data, det vill säga data som sällan eller aldrig används. Sovande data påverkar en organisations datalager negativt eftersom den försämrar datalagrets prestanda, kostar pengar i onödan och påverkar datalagrets infrastruktur negativt. Enligt Inmon, Glassey och Welch (1997) är det en mycket svår och komplex process att rensa ut sovande data ur sitt datalager. Administratören måste ha kunskap om vilka datatabeller i datalagret som används och vilka rader utav data som används för att kunna ta bort data från datalagret. Enligt Inmon m.fl.
Strukturerat lärande genom Action Design Research. En studie om visualisering av behörigheter
As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.
Uppväxtmiljö och i uppväxtmiljön förvärvad djurvana hos elever vid naturbruksgymnasium : Home environment and in home environment acquired animal experience in students of agricultural college
In all types of learning situations, it is important to find each student where they are at the moment in knowledge. I have reflections about what animal experience students have with them when they begin their education. This thesis is about what home environment and in home environment acquried animal experience student at agricultural college have. This work is based on data collected through questionnaire survey done in two agricultural colleges in middle Sweden in the spring of 2007. Questions were divided into four blocks, historical data such as on the environment in which pupils are growing up, animal habit, why they read on agricultural school and future data on what plans students have for future education and careers.
Allmänhetens arkiv? : En studie av tre participatory archives
The aim of this study is to examine how and in what way users of the public participate and affect the archival information that is to be preserved for the future through the examination of three archival projects involving public participation. The study seeks to examine if participation of the public could lead to increased democracy and diversity of information in the archives. The study will be performed through the examination of three participatory archives all tied to traditional archival institutions.The study is based on the theoretical framework of Benn and Gaus and their notions of public and private which they discuss using the key words access, agency and interest. The study also takes into consideration Laura Millar?s theories of social memory as a means for the public good.
