  1. 16. A Software Framework for Prioritized Spectrum Access in Heterogeneous Cognitive Radio Networks

    Author : Yong Yao; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cognitive Radio Networks; Queueing Modelling; Spectrum Decision; Fuzzy-Logic; Cellular Network; Ad-Hoc Network; Mesh Network;

    Abstract : Today, the radio spectrum is rarely fully utilized. This problem is valid in more domains, e.g., time, frequency and geographical location. READ MORE

  2. 17. Methods and techniques for precise and accurate in-duct aero-acoustic measurements : Application to the area expansion

    Author : Luck Peerlings; Susann Boij; Hans Bodén; Yves Aurégan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-expansion; Scattering matrix; Multi-microphone method; Engineering Mechanics; Teknisk mekanik;

    Abstract : During the design and commissioning of combustion equipment, combustion associated instabilities are commonly encountered. These thermo-acoustic instabilities can cause undesirable noise, vibrations, local thermal and mechanical stresses in the combustor and are prominent in lean combustion. READ MORE

  3. 18. Temporal Characteristics of Boreal Forest Radar Measurements

    Author : Albert Monteith; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; antenna array; Synthetic aperture radar; temporal coherence; tomography; backscatter; remote sensing;

    Abstract : Radar observations of forests are sensitive to seasonal changes, meteorological variables and variations in soil and tree water content. These phenomena cause temporal variations in radar measurements, limiting the accuracy of tree height and biomass estimates using radar data. READ MORE

  4. 19. Supply Chain Risk Management : Identification, Evaluation and Mitigation Techniques

    Author : S.Nurmaya Musa; Ou Tang; Jan Olhager; David Zhang; Linköpings universitet; []
    Keywords : Supply chain risk management; risk analysis; risk control; co-citation; system dynamics; modelling;

    Abstract : Supply chains have expanded rapidly over the decades, with the aim to increase productivity, lower costs and fulfil demands in emerging markets. The increasing complexity in a supply chain hinders visibility and consequently reduces one’s control over the process. READ MORE

  5. 20. On the use of immersive technologies in the professional education of mineral processing

    Author : Pedro A. de S. Bergamo; Yousef Ghorbani; Jan Rosenkranz; Emilia Sofia Streng; Saija Luukkanen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Training Evaluation; Modelling and Simulation; Gamification; User Experience; Mineral Processing; Mineralteknik;

    Abstract : With the advance of technology, many educators started implementing immersive technologies like simulators and gamified learning applications to improve the trainings of process operators. However, it is noted that the minerals sector is significantly behind other industries, for instance, the chemical industry, especially when it comes to the evaluation of these types of trainings.
