  1. 21. Large Eddy Simulation of Swirling Reacting Flows

    Författare :Mohammad Irannezhad; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; Swirling flow; Large Eddy Simulation;

    Sammanfattning : The combustion of fossil fuels remains a key technology as these fuels are the main source of energy in the foreseeable future. Heat released in combustion is often accompanied by emission of undesired soot, CO and NOx pollutants. LÄS MER

  3. 22. Large Eddy Simulation of Turbulent Compressible Jets

    Författare :Bernhard Semlitsch; Mihai Mihaescu; Laszlo Fuchs; Paul G. Tucker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressible Flow; Large Eddy Simulation; Acoustic Noise Generation; Near-field Acoustics; Flow Control; Optimization; Modal Flow Decomposition; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Acoustic noise pollution is an environmental aggressor in everyday life. Aero- dynamically generated noise annoys and was linked with health issues. It may be caused by high-speed turbulent free flows (e.g. LÄS MER

  4. 23. Constructing Large Multilingual Proposition Databases

    Författare :Peter Exner; Institutionen för datavetenskap; []
    Nyckelord :;

    Sammanfattning : This thesis explores methods for generating proposition databases in a large-scale and multilingual setting. Our methods are centered on using semantic role labeling for extracting predicate-argument structures, and the subsequent transformation of such structures for knowledge base population and generation.

  5. 24. Offset Management for Large Systems : A Multibusiness Marketing Activity

    Författare :Magnus Ahlström; Lars-Gunnar Mattsson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Offset; countertrade; industrial co-operation; systems selling; project marketing; package deal; turnkey; buying behaviour; governmental procurement; local content;

    Sammanfattning : Offset, an advanced form of countertrade, is common in the international marketing of large infrastructure and defence systems. Offsets are activities that benefit the buying country for example in the form of local content, support of exports, subcontracts and technology transfer. LÄS MER

  7. 25. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

    Författare :Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. LÄS MER
