  1. 1. Beskrivning och översättning av no da samt analys av Murakami Harukis Nejimakidori och Fågeln som vrider upp världen

    Kandidat-uppsats, Göteborgs universitet/Institutionen för språk och litteraturer

    Författare :Axel Eliasson; [2020-02-20]
    Nyckelord :japanska; no da; n da; Japanese nominal predicate; Swedish translation; Haruki Murakami; semantics; pragmatics;

    Sammanfattning : The purpose of this thesis is to give a description of the functions of the Japanese nominalpredicate no da, which in short is used to signal that the participants of a communication arealready aware of the information presented. However, the thesis´ main point of interest lies inthe analysis of the choice of words when no da is translated into Swedish. LÄS MER

  2. 2. Dispersion of cement-based grout with ultrasound and conventional laboratory dissolvers

    Master-uppsats, KTH/Byggvetenskap

    Författare :Antranik Karamanoukian; [2020]
    Nyckelord :ultrafine cement grout; microfine cement grout; dispersion; additives; ultrasound dissolver; laboratory dissolver; ultrafint cementbruk; mikrofin cementbruk; dispergering; tillsatser; ultraljud apparat; laboratorieblandaren;

    Sammanfattning : In any underground facilities especially tunnels, it is essential to seal the area against water ingress and leakage of reserved materials. Grouting is a common method used to seal rocks around tunnels, successful grouting reduces the duration and cost of the construction, guarantees better working environment and higher safety, minimizes the maintenance and most important decreases the corresponding environmental hazards significantly.

  3. 3. Test setup for LDMX HCal readout

    Kandidat-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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.

  4. 4. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anton Sundström; [2020]
    Nyckelord :DEM; Discrete element method;

    Sammanfattning : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. LÄS MER

  5. 5. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Simon Wredh; [2020]
    Nyckelord :computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

    Sammanfattning : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. LÄS MER
