  1. 11. Live 3D imaging quantum LiDAR

    University essay from KTH/Tillämpad fysik

    Author : Theodor Staffas; [2021]
    Keywords : lidar; otdr; snspd; lidar; otdr; snspd;

    Abstract : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. READ MORE

  3. 12. Using Graph Neural Networks for Track Classification and Time Determination of Primary Vertices in the ATLAS Experiment

    University essay from KTH/Matematisk statistik

    Author : Mattias Gullstrand; Stefan Maraš; [2020]
    Keywords : Time determination; graph neural network; graph attentional network; HGTD; vertex; node classification; particle physics; machine learning; Tidsbestämning; neurala grafnätverk; uppvaktande grafnätverk; HGTD; vertex; nodklassificering; partikelfysik; statistisk inlärning;

    Abstract : Starting in 2027, the high-luminosity Large Hadron Collider (HL-LHC) will begin operation and allow higher-precision measurements and searches for new physics processes between elementary particles. One central problem that arises in the ATLAS detector when reconstructing event information is to separate the rare and interesting hard scatter (HS) interactions from uninteresting pileup (PU) interactions in a spatially compact environment.

  4. 13. Improved Precision Time Protocol with Relative Clock Phase Information

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Avneesh Vyas; [2020]
    Keywords : ;

    Abstract : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. READ MORE

  5. 14. Utvärdering av varierad mängd utsäde och gödning i maltkorn : är det lönsamt?

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Sofia Ramgren; [2020]
    Keywords : precisionsodling; maltkorn; varierad giva; försöksodling; Alnarps Egendom; lerhalt; markkartering; proteinhalt;

    Abstract : Teknikutvecklingen inom lantbruket går fort och det kan vara svårt att veta vilken teknik som man ska investera i. Framförallt är det svårt att veta om den är lönsam. Precisionsodling är en del i denna utveckling och används hos vissa lantbrukare. READ MORE

  6. 15. Plant phenology and climate change : possible effect on the onset of various wild plant species first flowering day in the UK

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nigel Fox; [2019]
    Keywords : geography; GIS; plants; phenology; climate change; global warming; FFD; IPCC; Bluebell; Garlic mustard; Coltsfoot; Cuckooflower; United Kingdom; Woodland Trust; UK; Earth and Environmental Sciences;

    Abstract : The IPCC states that the planet is significantly warming due to effects of climate change. This warming effect has consequences for phenological events. Many species cannot track rapid climate change, resulting in phenological mismatches. This study looks at an extreme weather event and the longer-term effects of climate change. READ MORE
