  1. 1. New Techniques for Building Timing-Predictable Embedded Systems

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Nan Guan; Uppsala universitet.; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; WCET analysis; cache analysis; abstract interpretation; multiprocessor scheduling; fixed-priority scheduling; EDF; multi-core processors; response time analysis; utilization bound; real-time calculus; scalability; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : Embedded systems are becoming ubiquitous in our daily life. Due to close interaction with physical world, embedded systems are typically subject to timing constraints. At design time, it must be ensured that the run-time behaviors of such systems satisfy the pre-specified timing constraints under any circumstance. LÄS MER

  2. 2. Exploring the Propanediol Utilization Pathway in Lactobacillus reuteri

    Detta är en avhandling från Division of Biotechnology, Lund University

    Författare :Lu Chen; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus reuteri; propanediol utilization pathway; microcompartment; shell proteins; glycerol; 3-hydroxypropionaldehyde; 3-hydroxypropionic acid; 1; 3-propanediol; glycerol dehydratase; 1; 3-propanediol oxidoreductase; propionaldehyde dehydrogenase; redox balance; substrate selectivity;

    Sammanfattning : Concerns regarding environmental issues have led to increasing efforts for investigating sustainable production routes for the future industry that is based on renewable resources. Among the biobased chemicals, the C3-chemicals 3-hydroxypropionaldehyde (3-HPA), 1,3-propanediol (1,3-PDO) and 3-hydroxypropionic acid (3-HP), have been identified as top candidates for the chemical industry.

  3. 3. Utilization of terrestrially derived dissolved organic nitrogen by aquatic bacteria

    Detta är en avhandling från Limnology, Department of Ecology, Lund University

    Författare :Ramunas Stepanauskas; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; amino acids; spring flood; UV radiation; estuarine mixing; microbial loop; bacterial bioassays; marine eutrophication; bioavailability; Dissolved organic nitrogen; DON; extracellular aminopeptidase; Baltic Sea; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : I investigated the bacterial utilization of terrestrially derived dissolved organic nitrogen (DON) in aquatic ecosystems, and assessed the potential role of river-born DON in marine eutrophication. To determine the bioavailability of DON, I developed a bioassay employing N-limited bacterial regrowth cultures, which were calibrated with additions of inorganic nitrogen. LÄS MER

  4. 4. System studies of MCFC power plants

    Detta är en avhandling från Stockholm : KTH

    Sammanfattning : Die Brennstoffzelle ist ein elektrochemischer Reaktor und wandelt chemisch gebundene Energie direkt in elektrische Energie um. In der stationären Energieerzeugung ist der Brennstoffzellenstapel selbst nur ein kleiner Bestandteil des vollständigen Systems. LÄS MER

  5. 5. Early-Decision Decoding of LDPC Codes

    Detta är en avhandling från Linköping : Linköping University Electrnoic Press

    Författare :Anton Blad; Oscar Gustafsson; Erik G. Larsson; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECC; LDPC; communication; coding; decoding; low-power; Tanner; iterative algorithms; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Sammanfattning : Since their rediscovery in 1995, low-density parity-check (LDPC) codes have received wide-spread attention as practical capacity-approaching code candidates. It has been shown that the class of codes can perform arbitrarily close to the channel capacity, and LDPC codes are also used or suggested for a number of important current and future communication standards.
