  1. 1. Exploring Alternative Massive MIMO Designs Superimposed Pilots and Mixed-ADCs

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Daniel Verenzuela; Emil Björnson; Luca Sanguinetti; Michalis Matthaiou; Mohamad Assaad; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The development of information and communication technologies (ICT) provides the means for reaching global connectivity that can help humanity progress and prosper. This comes with high demands on data traffic and number of connected devices which are rapidly growing and need to be met by technological development. LÄS MER

  4. 4. Foliated Transportation Networks - Evaluating feasibility and potential

    Detta är en avhandling från Department of Ecology, Lund University

    Författare :Joakim Kalantari; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid transportation systems; transportation network modeling; intelligent transportation systems.; transportation planning and control; transportation network simulation; transportation network optimization; Transportation networks; transportation network performance; mixed model transportation; transportation network efficiency;

    Sammanfattning : Neither the critical role that transportation plays for economic activities nor its negative external effects can be denied. At the same time, the resources required to sustain and develop the transportation system to an adequate degree and at the required pace are limited. LÄS MER

  5. 5. Nutrient imbalance in Norway spruce

    Detta är en avhandling från Plant Ecology, Ecology Building, SE-223 62 Lund

    Författare :Gunnar Thelin; Lund University.; Lunds universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Sammanfattning : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. LÄS MER
