This paper deals with new forms of political mobilisation and participation in social media. The main focus is on the importance of social networks in providing a “media filter”, functioning as a kind of collective gatekeeper to spread news and information perceived as important, in contrast to the image of the single individual media consumer faced with an insurmountable mass of information. I ar

he surface structure of Bi(110) has been investigated by low-energy electron diffraction (LEED) intensity analysis and by first-principles calculations. Diffraction patterns at a sample temperature of 110 K and normal incidence reveal a bulk truncated (1×1) surface without indication of any structural reconstruction despite the presence of dangling bonds on the surface layer. Good agreement is obt

Popular Abstract in Swedish Språklig bearbetning och kontextuell påverkan En studie av förskolebarn med språkstörning Bakgrund Avhandlingen behandlar olika aspekter av språklig bearbetning hos barn med språkstörning. Barn med språkstörning har svårt att tillägna sig sitt modersmål trots att de växer upp i en enspråkig miljö. Dessa barn får problem i förskolan och ofta senare under skolåren efterLanguage Processing and Contextual Influence A Study of Swedish Preschool Children with Language Impairment The aim of the present work was to study different types of contextual influence on language performance in a variety of tasks: repetition of nonwords, narration, understanding of idioms and picture naming in a group of Swedish preschool children with language impairment (LI). The stress p

Det främsta syftet med detta expertutlåtande är att göra äldre teknikanvändare tydligare och föreslå åtgärder som motverkar diskriminering, okunskap och osynliggörande av äldre i innovationsprocesserna. Expertutlåtandets bedömning är nämligen att det i huvudsak är sådana brister som tenderar att hålla kvar föreställningarna om äldre som passiva och behövande mottagare, rent av som offer för ny tek

The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create gen

A consortium of interested parties has conducted an experimental characterization of two Tau parallel kinematic machines which were built as a part of the EU-funded project, SMErobot1. Characteristics such as machine stiffness, work envelope, repeatability and accuracy were considered. This paper will present a brief history of the Tau parallel machine, the results of this testing and some comment

Abstract in Undetermined The present dissertation is an investigation of the extant MS material representing Arabic version, translated from Pedhitta, of the Book of Ruth. Seven Arabic MSS, ranging from the 13th to the 17th century, are investigated and classified according to their origins.

Popular Abstract in Swedish Denna avhandling presenterar några reglertekniska tillämpningar i elkraftsystem. Tillämpningarna är: hur likströmskablar påverkar båtrafik som använder magnetkompasser; frekvensmätning i elkraftsystem; algorithmer för datorbaserade reläskydd; koppling av aktiv last för att dämpa effektpendlingar.This thesis presents some control applications in electric power systems. The work consists of the four parts: interaction between DC cables and ship steering autopilots; frequency estimation; computer relaying; field tests using load switching to damp power oscillations. The first three parts are based on four papers that are given in Appendix A-D. The thesis presents supplementary text to these

Channel codes in combination with iterative decoding techniques are a both powerful and efficient method to protect data against disturbances in digital communication systems. This thesis deals with various code constructions for block-wise and continuous transmission that have the potential to achieve low bit error rates with iterative decoding, even when operating close to the Shannon limit.
