  2. 21. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

    Author : Henrik Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

    Abstract : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

  4. 22. HAM-Tools - An Integrated Simulation Tool for Heat, Air and Moisture Transfer Analyses in Building Physics

    Author : Angela Sasic Kalagasidis; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HAM transfer; Whole building HAM model; Simulink modeling; International Building Physics Toolbox;

    Abstract : HAM-Tools is a building simulation software. HAM stands for Heat, Air and Moisture transport processes in a building and building envelope that can be simulated by this program, and Tools describes its modular structure. The main objective of this tool is to obtain simulations of transfer processes related to building physics, i.e. READ MORE

  5. 23. Physical Modeling and Control of Low Temperature Combustion in Engines

    Author : Anders Widd; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this thesis is model-based control of two combustion engine concepts, Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), using physics-based models. The studied combustion concepts hold promise of reducing the emission levels and fuel consumption of internal combustion engines. READ MORE

  6. 24. Scalable Parallelization of Expensive Continuous Queries over Massive Data Streams

    Author : Erik Zeitler; Tore Risch; Elke Rundensteiner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : Numerous applications in for example science, engineering, and financial analysis increasingly require online analysis over streaming data. These data streams are often of such a high rate that saving them to disk is not desirable or feasible. Therefore, search and analysis must be performed directly over the data in motion. READ MORE

  7. 25. Multi-Photon Interactions with a Time Structure

    Author : Alexander Baev; KTH; []
    Keywords : nonlinear optics; two-photon absorption; mirrorless lasing; charge-transfer chromophores; solutions; resonant photoemission; life-time vibrational interference; scattering duration time; electron Doppler effect; polymers;

    Abstract : The present thesis concerns aspects of the interaction ofmatter in gas, liquid and solid phases, with electromagneticradiation, ranging from the optical to the X-ray region. Overthe last decade the availability of ultrashort strong laserpulses as well as of high power synchrotron sources of tunableX-ray radiation has stimulated a rapid development of newexperimental techniques which makes it possible to analysedifferent physical, chemical and biological processes inunprecedented detail.
