  1. 11. Optimal Networking in Wirelessly Powered Sensor Networks

    Författare :Rong Du; Carlo Fischione; Ming Xiao; Aylin Yener; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless energy transfer; network lifetime; energy beamforming; IoT; smart cities; sensor networks; scheduling; optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless sensor networks (WSNs) are nowadays widely used for the long-term monitoring of small or large regions, such as lakes, forests, cities, and industrial areas. The performance of a WSN typically consists of two aspects: i) the monitoring performance, e.g. LÄS MER

  3. 12. Optimal thinning : a theoretical investigation on individual-tree level

    Författare :Peter Fransson; Åke Brännström; Ola Lindroos; Oskar Franklin; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest management; Simulation; Optimization; Spatially explicit model; Individual-based model;

    Sammanfattning : Paper I: In paper I, we asked how a tree should optimally allocate its resources to maximize its fitness. We let a subject tree grow in an environment shaded by nearby competing trees. The competitors were assumed to have reached maturity and had stopped growing, thus creating a static light environment for the subject tree to grow in. LÄS MER

  4. 13. Pd-nanoalloys for hydrogen sensing: Multiscale modeling of thermodynamic and optical properties

    Författare :Pernilla Ekborg-Tanner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pd-alloys; hydrogen sensing; surface segregation; nanoplasmonics; nanoalloys;

    Sammanfattning : Hydrogen sensing based on Pd nanoalloys has shown great promise in the past decades and could potentially be part of a solution that enables a safe future hydrogen economy. There are, however, remaining challenges related to, e.g., long-term stability and a need for further optimization of these systems. LÄS MER

  5. 14. Gas Sensing Based on Ellipsometric Readout : Methodology and Development

    Författare :Guoliang Wang; Herbert Wonneester; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The concept of an ellipsometric sensor array system - "an optical nose" - is presented. The system is used to monitor and discriminate gases. The optical readout is based on polarizer-compensator-sample-analyzer (PCSA) off-null ellipsometry. LÄS MER

  7. 15. Integrated Sensing and Communication in Cell-Free Massive MIMO

    Författare :Zinat Behdad; Cicek Cavdar; Ki Won Sung; Özlem Tugfe Demir; Huseyin Arslan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated sensing and communication; cell-free massive MIMO; power allocation; URLLC; C-RAN; convex-concave programming.; Integrerad avkänning och kommunikation; cellfri massiv MI- MO; effektallokering; URLLC; C-RAN; konvex-konkav programmering;

    Sammanfattning : Future mobile networks are anticipated to not only enhance communication performance but also facilitate new sensing-based applications. This highlights the essential role of integrated sensing and communication (ISAC) in sixth-generation (6G) and beyond mobile networks. LÄS MER
