  4. 4. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Edvin Sidebo; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; p p: scattering; ATLAS; LHC; charged particle: multiplicity; semiconductor detector: pixel; neural network: performance; track data analysis: cluster; charged particle: cluster; splitting; CERN LHC Coll; Physics; Fysik;

    Abstract : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. READ MORE

  5. 5. Decentralized Network Optimization in Wireless Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yuzhe Xu; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Distributed estimation and distributed resource allocation are two important services in future cyber-physical wireless networks. The former aims to estimate, or track, physical variables of a phenomenon monitored by a wireless network, whereas the latter aims to optimally assign the limited communication resources to the nodes in a wireless network.
