  1. 16. Modeling, Control and Optimization of theTransient Torque Response in DownsizedTurbocharged Spark Ignited Engines

    Författare :Oscar Flärdh; Håkan Hjalmarsson; Jonas Mårtensson; Per Tunestål; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine modeling; Engine control; Transient torque response; Downsizing; Transient optimization;

    Sammanfattning : Increasing demands for lower carbon dioxide emissions and fuel consumption drive technological developments for car manufacturers. One trend that has shown success for reducing fuel consumption in spark ignited engines is downsizing, where the engine size is reduced to save fuel and a turbocharger is added to maintain the power output.

  3. 17. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle

    Författare :Mats Walldén; Johan Elf; Peter Graumann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E.coli; cell cycle; replication initiation; transcription factor; gene-regulation; single molecule microscopy; microfluidics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. LÄS MER

  4. 18. Advanced algorithms for logic synthesis

    Författare :Petra Färm; KTH; []
    Nyckelord :;

    Sammanfattning : In this thesis, new algorithms for logic synthesis areexplored. Our work is motivated by two observations: (1)Traditional logic synthesis applies literal count as theprimary quality metric during the technology independentoptimization phase. LÄS MER

  5. 19. Detector Considerations for Time-of-Flight in Positron Emission Tomography

    Författare :Florian Bauer; Christian Bohm; Magnus Dahlbom; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron Emission Tomography; Time of Flight; Depth of Interaction; LSO; Radiological physics; Radiofysik; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Positron-Emission-Tomography (PET) is a modern imaging technique in nuclear medicine providing quantitative 3D distribution of a radioactive tracer substance in the human body. The gamma-detector is the first link in the chain of components that constitutes a PET. LÄS MER

  7. 20. Phosphorus transport in the landscape – Integrating high-frequency monitoring, phosphorus geochemistry and modelling to improve water management

    Författare :Emma Lannergård; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Eutrophication is one of today’s most challenging water quality issues, despite considerable efforts to reduce phosphorus (P) input to surface waters. We need to explore new tools and techniques to improve the nutrient status of our waters and facilitate the management of catchment-scale P transport. LÄS MER
