  1. 1. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Eduardo Salvador Lopez; [2023]
    Nyckelord :Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

    Sammanfattning : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. LÄS MER

  3. 2. Omvärldsanalys i samhällsviktig verksamhet : En studie om regioners arbete med risk- och sårbarhetsanalys utifrån en verksamhetsteoretisk ansats

    Master-uppsats, Karlstads universitet

    Författare :Mimmi Selin; [2023]
    Nyckelord :Horizon scanning; risk- and vulnerability analysis; county council.; Omvärldsbevakning; omvärldsanalys; risk- och sårbarhetsanalys; regioner;

    Sammanfattning : Introduktion: Omvärldsbevakning/analys är ett förekommande krav för organisationer som ett led i att tidigt identifiera omvärldens påverkan på den egna organisationen samt som underlagför att kunna fatta gynnsamma beslut. Det finns ingen allmängiltig definition eller vedertagen metod när det gäller omvärldsbevakning/analys i offentlig verksamhet. LÄS MER

  4. 3. Surface Functionalization of Nanowires Using Silane-PEG Compounds

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Hedvig Ekfors Elvin; [2022]
    Nyckelord :Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Sammanfattning : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. LÄS MER

  5. 4. The copper sulphide mineralization of the Zinkgruvan Deposit, Bergslagen, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Karolina Bjärnborg; [2009]
    Nyckelord :Zinkgruvan; copper sulphide mineralization; chalcopyrite; cubanite; kopparsulfidmineralisering; kopparkis; kubanit; Earth and Environmental Sciences;

    Sammanfattning : At Zinkgruvan, Sweden, zinc, lead and silver are mined from a stratiform ore body. It is considered syngenetic and situated in metavolcanic and metasedimentary rocks. A fault, the Knalla fault, separates the Zinkgruvan deposit into two parts. LÄS MER

  7. 5. Topography, soil carbon-nitrogen ratio and vegetation in boreal coniferous forests at the landscape level

    L3-uppsats, SLU/Dept. of Forest Soils

    Författare :Guillermo Chaminade; [2005]
    Nyckelord :C N ratio; TWI; soil properties; vegetation; landscape;

    Sammanfattning : This thesis was developed with the main objective of assessing the mutual influence of three of the main factors taking part in the ecological processes of the boreal forest: topography and the hydrological fluxes related to it, C/N ratio in the forest soil, and vegetation composition. The interaction between these factors has not been the main focus in any study of this kind before, although in numerous reports these variables and their role in the forests have been assessed.
