  1. 1. Conditions for relatives' involvement in nursing homes

    Detta är en avhandling från Karolinska Institutet

    Författare :Jessica Holmgren; Henrik Eriksson; Lars E Eriksson; Eric Carlström; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; discourse analysis; focused ethnography; focus group interviews; gender perspectives; intersectionality; involvement; nursing homes; nursing staff; participant observations; qualitative interviews; relatives; social constructionism and thematic analysis;

    Sammanfattning : The overall aim of this thesis was to describe and analyse how the involvement of relatives is conditioned in nursing homes from different critical perspectives. Gender perspectives, discourse analysis and intersectional theory are applied, based on social constructionist ontology. LÄS MER

  2. 2. Single-Zone Cylinder Pressure Modeling and Estimation for Heat Release Analysis of SI Engines

    Detta är en avhandling från Institutionen för systemteknik

    Författare :Markus Klein; Lars Eriksson; Lars Nielsen; Per Tunstål; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heat release; parameter estimation; prior knowledge; regularization; specific heat ratio; compression ratio; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik Systemteknik;

    Sammanfattning : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. LÄS MER

  3. 3. Modelling for Fuel Optimal Control of a Variable Compression Engine

    Detta är en avhandling från Institutionen för systemteknik

    Författare :Ylva Nilsson; Lars Eriksson; Lars Nielsen; Richard K. Stobart; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion engine; modelling; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Variable compression engines are a mean to meet the demand on lower fuel consumption. A high compression ratio results in high engine efficiency, but also increases the knock tendency. On conventional engines with fixed compression ratio, knock is avoided by retarding the ignition angle. LÄS MER

  4. 4. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER
