Individual identification of pigs could be used in commercial herds for production monitoring, disease monitoring and breeding evaluation. This study investigates the possibility of using microchips designed for dogs and cats to identify individual pigs from birth, through rearing to carcass at the slaughter plant. Two different sizes of microchips, and two different ages of the pigs at injection were tested. Castrates and gilts from ten litters were evenly distributed between chip sizes and injection ages. All pigs were identity marked with both electronic ear tags and injected with microchips.

Företag inom alla branscher arbetar aktivt med att minska sina kostnader genom ökad effektivitet i interna processer, så är även fallet inom daglivarubranschen. Ett sökande efter ny teknik och nya sätt att utveckla branschen står alltid på dagordningen. Radio frequency IDentification (RFID) är nästa generations identifieringsteknik för dagligvaruhandeln, det är därför viktigt att tekniken börjar implementeras och användas. Svenska Retursystem är ett företag som tillhandahåller returlådor till den Svenska livsmedelsbranschens aktörer. För att effektivisera användandet av lådorna så har de givit uppdrag om en undersökning om vilka effekter införandet av RFID i deras returlådor skulle ha på användandet.

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

The Swedish population is today exposed to more ads than ever. The number of advertising channels is growing, as well as the number of companies and their advertising expenses. As the products are becoming more alike, the harder it gets for the companies to convince the consumers their product is better than their competitors?. In order to succeed they need to understand what they communicate to the consumers through their different marketing activities, and how that affects the consumers? view of the brand and the product.

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Denna fallstudie syftar till att undersöka hur Sveriges Radio i egenskap av public serviceföretag kommunicerar externt. Vi finner det intressant att undersöka hur en offentlig medieorganisation, utanför den kommersiella marknaden, arbetar med sin externa kommunikation. Genom en kombination av kvalitativa metoder och teori rörande strategisk kommunikation, varumärke, publika relationer samt sociala medier, berörs studiens fyra frågeställningar: Vad har Sveriges Radio för kommunikationsmål? Vilka strategier går att urskilja i Sveriges Radios kommunikativa arbete? Hur använder Sveriges Radio sociala medier i sin kommunikation? På vilket sätt påverkar public service-ideologin Sveriges Radios externa kommunikation? Mer specifikt undersöks hur Sveriges Radio bygger och upprätthåller relationer till publiken samt kommunicerar sitt varumärke, bland annat genom sociala medier.Studien bygger på kvalitativa intervjuer med representanter från Sveriges Radio, samt en retorisk analys av material från SR:s officiella sociala medier. Resultatet visar att Sveriges Radio har implicita kommunikationsmål som är en del av verksamhetsmålen.

This paper discusses how four people in the Swedish Radio station P3, together interact to account therapy trends towards a third party. The focus is on whether, and if so, how they collaborate to make the conversation intelligible for radio listeners. This is done by means of conversation analysis and methods developed by the CA. The result is interesting when the conversation participants do not follow their expected roles as broadcasters and experts while they disagree about the communicative projects to be carried out..

This study aims to map out the degree of mediatization present in the communication between Swedishpublic service journalists and politicians in the 2014 election campaign. In doing so we chose to look at thepresence of media logic in their communication with each other. Specifically, we have used the pre-electioninterviews with the party leaders from Sweden?s two biggest parties. Furthermore, we have chosen to focuson Sveriges Radio, the Swedish public service radio company.Sveriges Radio concists of four different radio channels, of which we have chosen to focus on the channelsP1 and P3, the first having a somewhat more ?serious? profile, focused on producing quality news and otherjournalistic products, while P3 is leaning towards a younger audience and describes its own work as ?soft,humorous and important radio?, mixed with music and other forms of entertainment.

Event marketing has during the last decade become a wide spread marketing method. This is because the marketing clutter has increased heavily during the past years and brands are looking for new ways to reach their target audience. The previously well accepted marketing measurement "satisfaction" has shown tendencies no longer to be sufficient for success in today's competitive marketplace. Therefore, the research has somewhat moved to the measurement "brand love" to explain differences in strategic consumer behavior. That is the background to why this report examines and answers the question if a brand through event marketing can enhance brand love.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

This thesis deals with the field of warehouse management, focusing on frequency control of stock. The purpose of the thesis is to reduce the warehouse staff mileage by placing an article based on its number of picks, i.e. how frequently it gets picked. In order to achieve relevant results the following four questions have been answered in the thesis: How should the articles be placed with regard to the picking frequency?Which factors, if any, needs to be addressed beyond the picking frequency when articles are placed based on frequency?Can the present picking system be improved?Is frequency placement with regard to the picking frequency profitable to implement for the company?The thesis is based on literature studies and on the data that has been collected from the company?s business system.
