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.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

Abstract:Title: The popular blog ? on updating and its effects on vistor statisticsNumber of pages: 35Author: Wilhelm von SydowTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Autumn 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: To examine to which, if any, extent the update frequency of blogs affects their visitor statistics.Material/Method: Quantitative method, Swedish blogs, visitor statistics and updating frequency.Main results: No results could prove the causal effects of the relation between visitor statistics and updating frequency. A noticeable connection between the two variables could, however, be identified.Keywords: Blog, update frequency, visitor statistics, quantitative, Habermas, public sphere, Else Nygren, intranet, Matt Haig, business websites.

The purpose of this study is to investigate librarian?s opinions concerning literature with state supported distribution and how to mediate and market these in the library. The types of mediation and marketing that have been studied are positioning, labeling and oral mediation.The study is qualitative with interviews at seven main public libraries in central Sweden. The respondents of the study were responsible for the literature with state supported distribution within the library.The study is based on a theoretical frame of reference containing theories from Jofrid Karner Smidt, regarding librarian?s mediation in libraries, and François Colbert?s theory on marketing planning for arts and culture.The results of our study showed that librarians have both positive and negative opinions when it comes to the literature with state supported distribution.

It is important that the language in textbooks for foreign language learners reflects the language that the learners would encounter in real life. For this reason, the presence of the thousand most common nouns in two Swedish textbooks in Spanish for upper secondary school is observed in this study. Furthermore, this study aims to examine how these nouns occur in order to determine if their pattern of occurence favours the learning and consolidation of words. The main materials that have been used are A Frequency Dictionary of Spanish by Davies (2006) and the word search program available in the digital versions of the textbooks. The results show that the presence of the thousand most common Spanish nouns does reflect the frequency information presented in the frequency dictionary but not all thousand nouns are included.
