  1. 1. 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.

  2. 2. Lyman Continuum Radiation from Intermediate-Mass Black Holes : An Estimation of the Contribution of LyC Radiation from IMBHs in z~3 Galaxies

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Marika Ljungberg; [2020]
    Keywords : intermediate-mass black holes; cosmic reionization; high-redshift galaxies;

    Abstract : This thesis concerns the cosmic reionization of the intergalactic medium in the high redshift universe and, in particular, is a first approach to examine what role intermediate mass black holes (IMBHs) play in this cosmic age. Unexpectedly high values of hydrogen ionizing radiation, compared to current models, have been reported from galaxies at redshift ~3 (used as stand-ins for galaxies at the age of reionization), and thus these models need revision, potentially by adding effects of IMBH content in the galaxies.

  3. 3. Prediction of Process Parameters for Powder Bed Fusion Using Electron Beam

    University essay from KTH/Materialvetenskap

    Author : Teodor Haglund; [2020]
    Keywords : EBM; PBF-EB; Power Bed Fusion; Process Parameters; Parameters; Prediction;

    Abstract : The Powder Bed Fusion using Electron Beam (PBF-EB) process is a highly complex additive manufacturing process. There are a very limited number of materials that have been used successfully, which limits the applications of the process, despite its well-documented advantages over conventional manufacturing.

  4. 4. Magnetic Activated Carbon Production from Lignin and Ferrous Salts : Process Modification for Enhanced Phosphate Adsorption from Aqueous Solutions

    University essay from KTH/Materialvetenskap

    Author : Zhaoran Zheng; [2020]
    Keywords : Magnetic bio-activated carbon; phosphate adsorption; lignin; steam activation.; Magnetiskt bioaktiverat kol; fosfatadsorption; lignin; ångaktivering;

    Abstract : The treatment and control of superfluous aqueous phosphate is a critical task in environmental management. Magnetic bio-activated carbon is a good adsorbent for physical adsorption methods with several environmental and economic advantages. READ MORE

  5. 5. Virtual Commissioning of an industrialwood cutter machine : A software in the loop simulation

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Montero Vera Edgar Alexander; [2020]
    Keywords : Virtual commissioning; PLCSIM advanced; digital twin; mechatronics concept designer; SIMIT; TIA Portal; PLC; HMI; software in the loop.;

    Abstract : The methods used today for the commissioning and validation of industrial machines requires theconstruction of physical prototypes. Those prototypes help the engineers to e.g. validate if theprogram code meant to control a machine works as intended. READ MORE
