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

    Author : Nan Guan; Wang Yi; Lothar Thiele; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Lu Chen; Bioteknik; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Ramunas Stepanauskas; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Cognitive Sensing and Transmission Strategies

    Author : Kasra Haghighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hidden Markov Model; Spectrum Sensing; Sequential Spectrum Sensing; Cognitive Radio; Spectrum Utilization;

    Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. READ MORE

  7. 5. System studies of MCFC power plants

    Author : Benny Fillman; Pehr Björnbom; Professor Mats Westermark; Gábor Merényi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cells; fuel cell systems; system studies; process simulation; molten carbonate; Brennstoffzellen; Brennstoffzellensystem; Systemanalyse; Prozeßsimulation; Bränsleceller; bränslecellssystem; systemstudier; processimulering; smältkarbonatbränslecell; Chemical engineering; Kemiteknik;

    Abstract : 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. READ MORE
