Taggade bibliotek ? en studie av adoptionen av RFID på svenska folkbibliotek
The purpose of our research was to examine whether the acceptance and diffusion of RFID technology among the employees at public libraries in Sweden, follow the classic diffusion of innovation model. RFID or Radio Frequency Identification, is a technology that uses radio frequency and microchip technology to track items, in our case, library books and other library materials. Diffusion is the process by which, in our case, the RFID technology is adopted by the library staff. The purpose of this study was to examine what factors influenced the acceptance and adoption of RFID among the library staff. We used Everett Rogers' Diffusion of innovation theory as our framework.
Interaktiva radiotjänster : - en applikation för mobila Androidenheter
The increase in sales of the so called smart phones has meant that there has also been a requirement to determine new applications for which they are suitable. One of the largest platforms for smart phones is Android and the task of this thesis is to develop an application for a company that wishes to create interactive radio for the Internet. In addition to ordinary radio features, the company would like the application to be able to present images and a small web page called Canvas. The overall aim ,of this thesis, is to build a fully functional media player that is compatible with the majority of the commonly used Android based mobile units. To fulfill the overall aim, nine explicit goals were targeted.
Public service och välfärd: konflikter, legitimitet och rättvisa
Med hjälp av filosofen John Rawls definition av rättvisa och David Beetham finner uppsatsen att dagens system med tv-licens dels skapar ett rättviseproblem och ett legitimitetsunderskott inom vissa grupper i samhället. Dessa grupper är vad Rawls skulle kategorisera som de sämst ställd. Rättviseproblemet uppstår p.g.a. det nuvarande systemet med en tvångsfinansierad avgift som inte tar hänsyn till människors inkomster. För att göra systemet rättvisare i Rawls mening finns det tre alternativ, 1) avskaffa public service, 2) finansiera public service via skattesedeln och 3) införa en frivillig avgift i den mening att de som använder public service är de som betalar..
Servicekvalitet på Göteborgs stadsbibliotek utifrån dyslektikers perspektiv
The aim of this paper is to examine how dyslectic adults define the service quality at the public library of Gothenburg. The purpose is also to investigate what level of service quality the library provides and which responsibilities the library has towards the dyslectics. Answers are sought to the following questions: - How do dyslectics perceive the service quality at the public library of Gothenburg and is that service quality satisfactory? - What responsibilities does the public library of Gothenburg have towards the dyslectics according to cultural policy documents? In this paper six persons have been interviewed. Of these, four are adult dyslectics, one works with people with special demands and the last one is the chief librarian.

Beteende inför lek hos odlad respektive vild lax (Salmo salar L.) i Klarälven
In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Från ett pedagogiskt läge till ett annat : En studie om invandrade elever som nyligen slussats ut i vanlig klass
Public Service är ett svårdefinierat begrepp. De gamla idealen handlar mycket om enmedieideologi som baseras på etermediernas möjligheter och begränsningar, vilket har skapatsvårigheter när Public Service har letat sig ut på Internet. Kritik från bland annatbranschorganisationen Tidningsutgivarna ifrågasätter Public Service-företagens breddning påwebben. De anser att gränserna för vad Public Service-företagen får och inte får göra äralltför otydliga.Med hjälp av fyra kvalitativa samtalsintervjuer (tre personer från Sveriges Television samt enfrån Tidningsutgivarna), och med kvalitativa textanalyser av statliga propositioner ochutredningar angående Public Service-uppdraget undersöks hur Public Service-uppdraget ochdess medieföretag påverkas av medieutvecklingen.I uppsatsen jämförs resultaten med Anna Maria Jönssons tankar kring Public Service och denmedieideologiska inriktningen ?Social ansvarsideologi?.

Varför har Pilevallskolan valt att arbeta med Service-Learning?
Vi har tittat på hur det amerikanska konceptet Service-Learning används på en svensk skola, Pilevallskolan i Trelleborg, hur och varför man valt att arbeta med det. Vi jämför också LPO-94 med resultatet av vår undersökning för att se om det är motiverat att arbeta med denna metod. Värdegrunden och en tolkning av denna är också av viss signifikans..
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.
Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..
