Computers are increasingly used for implementing controlalgorithms in safety-critical embedded applications, such asengine control, braking control and flight surfacecontrol. Addressing the consequent coupling of control performancewith computer related errors, this paper develops a composite computerdependability/control theory methodology for analyzing the effectsdata errors have on control syst

Popular Abstract in Swedish Denna avhandling behandlar olika metoder för datakompression och speciellt metoder som är lämpliga för komprimering av digitala bilder. Avsikten med datakompressionen är att finna en representation av den ursprungliga datan (tex en bild) som upptar mindre plats på tex ett skivminne.In this thesis various topics in universal lossless source coding are discussed and analyzed. The main focus in this work is on lossless data compression of grayscale still images. Such images are, for example, frequently occurring in medical imaging. Based on theoretical considerations and empirical observations new compression algorithms are presented that are, in terms of compression performan

Detta dokument beskriver huvuddragen i relationen mellan Course Experience Questionnaire (CEQ) och högskolepedagogik. Syftet är att visa på hur resultat från CEQ kan användas för pedagogisk utveckling. Därmed behandlar detta dokument kärnan i CEQ-tolkningsprocessen inom LTH:s system för rapporterande utvärdering, själva syftet med CEQ-utvärderingarna, samt LTH:s utvärderingssystems koppling till s

Popular Abstract in Swedish 75% av alla kemiska reaktioner sker på en yta av något slag. En av anledningarna till detta är att många ytor har en katalytisk effekt. Inom kemins värld är en katalysator något som påskyndar en kemisk reaktion utan att själv förbrukas, och ett tydligt exempel på en katalytiskt aktiv yta är en bilkatalysator, vilken i princip består av en varm metallyta. På denna yta omThis work deals with interpretation of experimental surface spectroscopic data with the aid of first-principle calculations. Surface infrared reflection-absorption spectra as well as spectra from the electron spectroscopic methods photoemission and X-ray absorption are considered. In all cases the surface is modeled by a metal cluster with the same (frozen) geometry as part of the surface. The wo

This study, commissioned by the Nordic Council of Ministers, aimed toprovide first proposals for targets and indicators that can be used in the Nordic countries' waste prevention programmes. Four waste streams were considered: food waste, construction- and demolition waste (C&D waste), waste electrical and electronic equipment (WEEE) and textile waste. Firstly, a literature review of internati

Popular Abstract in Swedish Avhandlingen är en granskning av ett antal psykologiska metoder i syfte att förbättra bedömning/diagnostik av två olika tillstånd förknippade med kontakt med kemikalier: (1) kronisk nedsättning av hjärnfunktion till följd av långvarig kontakt med lösningsmedel i yrket (toxisk encefalopati, förkortat TE), och (2) överkänslighet för kemikalielukter av okända orsaker (eng.The dissertation deals with psychological methods aimed at improving the understanding and assessment of two disorders related to contact with chemicals: solvent-induced chronic toxic encephalopathy (TE) and multiple chemical sensitivity (MCS). The main aim of Paper I was to study whether the addition of some newer psychological tests of complex attention and executive functions to a traditional

Designers create messages that are encoded in the products’ design and consumers perceive the products in an environment. Hence the product can be seen as a communication media between the designer and different product stakeholders. The stakeholder’s response to the designer’s intent embodied in the product design falls into three categories: cognitive, affective and behavioural. In some cases, i

An overview of the language cultivation (ideas, implementation, organization etc.) in Sweden in the 19th and 20th centuries.

We discuss the process of calibration and verification of learning strategies, and argue that a careful consideration of data from brain-imaging methodologies, as well as a systematic treatment of first-person subjective reports, is the most promising route for educational researchers to answer the age-old question about what a learning strategy really amounts to. In addition we argue that such co

This paper considers a house allocation problem with no initial ownership and where prices are bounded from below and above by exogenously given price restrictions. This type of housing market contains, e.g., the "assignment market" and the "student placement problem" as special cases. A mechanism called the minimal RPE mechanism is defined, and two main results are obtained. First, it is demonstr
