  1. 1. Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Fredrik Skärberg; [2020-11-26]
    Keywords : Deep learning; convolutional neural networks; image analysis; semantic segmentation; focused ion beam scanning electron microscopy; porous materials; controlled drug release;

    Abstract : Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopytechnique for 3D imaging of porous materials. We investigate three poroussamples of ethyl cellulose microporous films made from ethyl cellulose and hydroxypropylcellulose (EC/HPC) polymer blends. READ MORE

  2. 2. APTM and GRID signal processing and Errant beam detection at ESS

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Agnimesh Ghosh; [2020]
    Keywords : ESS; FPGA; Signal processing; Grid; APTM; Errant beam detection; Technology and Engineering;

    Abstract : The European Spallation Source (ESS) will be the world's most powerful next-generation neutron source. It will deliver a high-energy proton beam to the target with a high degree of control. With many components operating at their engineering limits, instrumentation must detect errant beam conditions and suppress proton beam production. READ MORE

  3. 3. Electrically Steerable Phased-Arrays for 5G Sub-6 GHzMassive MIMO Active Antenna Units : Re-configurable Feed Networks

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Johan Kövamees; [2020]
    Keywords : Electrically Steerable Phased-Arrays for 5G Sub-6 GHz Massive MIMO Active Antenna Units;

    Abstract : During this project we have designed a new type of antenna that uses an array of antenna elements in order to emit electromagnetic radiation as signals and to be able to control the beam. After an extended time the design yielded a simulation which had the correct characteristics. READ MORE

  4. 4. Test setup for LDMX HCal readout

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Joshua Greaves; [2020]
    Keywords : Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Abstract : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

  5. 5. Studying the Relation BetweenChange- and Fault-proneness : Are Change-prone Classes MoreFault-prone, and Vice-versa?

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM); Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Ahmad Abdilrahim; Caesar Alhawi; [2020]
    Keywords : Empirical software engineering; Change-proneness; Fault-proneness; Object-oriented; Metrics;

    Abstract : Software is the heartbeat of modern technology. To keep up with the new demands and expansion of requirements, changes are constantly introduced to the software, i.e., changes can also be made to fix an existing fault/defect. READ MORE
