  1. 21. Thermal Interference Between Neighbouring Ground-Source Heat Pumps : Tools to Calcualte it and Solutions to Limit it

    Författare :Maria Letizia Fascì; Joachim Claesson; Alberto Lazzarotto; Loius Lamarche; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pumps; thermal interference; neighbouring geothermal boreholes; finite line source; mitigation strategies; Energiteknik; Energy Technology;

    Sammanfattning : Ground Source Heat Pumps (GSHPs) have emerged as a promising technology for decarbonization of the heating sector. However, their increasing prevalence in densely populated areas may lead to considerable changes in the ground temperature, which can ultimately lead to reduced performance of the systems. LÄS MER

  3. 22. Phase Retrieval Methods for Electromagnetic Source Modeling

    Författare :Markus Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source modeling; optimization; SAR; phase retrieval; dosimetry;

    Sammanfattning : Modeling of the field distributions from electromagnetic sources is of interest for various applications including electromagnetic compatibility investigations, near-field to far-field transformations, antenna diagnostics and electromagnetic dosimetry. In order to determine whether exposure safety guidelines, such as the EU directive 2004/40/EC, are complied with, source modeling methods are important. LÄS MER

  4. 23. Towards Measuring & Improving Source Code Quality

    Författare :Umar Iftikhar; Nauman bin Ali; Jürgen Börstler; Muhammad Usman; Miroslaw Ochodek; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source code quality; Code review analysis; Software quality improvement; Programvaruteknik; Software Engineering;

    Sammanfattning : Context: Software quality has a multi-faceted description encompassing several quality attributes. Central to our efforts to enhance software quality is to improve the quality of the source code. Poor source code quality impacts the quality of the delivered product. LÄS MER

  5. 24. Source and Channel Coding for Audiovisual Communication Systems

    Författare :Moo Young Kim; Bastiaan Kleijn; Richard Heusdens; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Information theory; high-rate theory; source coding; channel coding; quantization; Telekommunikation; Telecommunication; Telekommunikation;

    Sammanfattning : Topics in source and channel coding for audiovisual communication systems are studied. The goal of source coding is to represent a source with the lowest possible rate to achieve a particular distortion, or with the lowest possible distortion at a given rate. Channel coding adds redundancy to quantized source information to recover channel errors. LÄS MER

  7. 25. Exploiting Sparse Structures in Source Localization and Tracking

    Författare :Maria Juhlin; Matematisk statistik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source localization; Cramér-Rao bounds; Convex Optimization;

    Sammanfattning : This thesis deals with the modeling of structured signals under different sparsity constraints. Many phenomena exhibit an inherent structure that may be exploited when setting up models, examples include audio waves, radar, sonar, and image objects. LÄS MER
