  1. 1. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :José Guilherme Rodrigues de Albuquerque Vale; [2023]
    Nyckelord :Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

    Sammanfattning : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). LÄS MER

  3. 2. Fabrication and Characterization of Quantum-well Field Effect Transistor

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Yang Fu; [2022]
    Nyckelord :quantum-well field-effect transistor; InGaAs; subthreshold swing; sheet resistance; contact resistance; electron mobility; Post Metallization Annealing; electrostatic control; Physics and Astronomy;

    Sammanfattning : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. LÄS MER

  4. 3. Modelling of nanometric cutting in metals using MD simulations

    Magister-uppsats, Lunds universitet/Mekanik

    Författare :Damien Gautier; [2022]
    Nyckelord :Nanometric cutting; Molecular Dynamics; Technology and Engineering;

    Sammanfattning : This master thesis project has been done within the Mechanics department of Lunds Tekniska Högskola (LTH). It studies the nanometric cutting process of a single crystal copper workpiece by a cubic diamond tool using Molecular Dynamics (MD) simulations on the software LAMMPS. LÄS MER

  5. 4. Regularized Fine-tuning Strategies for Neural Language Models : Application of entropy regularization on GPT-2

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Jae Eun Hong; [2022]
    Nyckelord :text generation; entropy regularization; neural language model; gpt-2;

    Sammanfattning : Deep neural language models like GPT-2 is undoubtedly strong at text generation, but often requires special decoding strategies to prevent producing degenerate output - namely repetition. The use of maximum likelihood training objective results in a peaked probability distribution, leading to the over-confidence of neural networks. LÄS MER

  7. 5. Influence of load distribution on trough bridges

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jacob Gustafsson; [2021]
    Nyckelord :Bridge; Trough bridge; Concrete; Load distribution; Ballast;

    Sammanfattning : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.
