  1. 1. 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

  3. 2. Synthesis and thermoelectric properties of Cr1-xMexN (Me = Mo, V)

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Victor Rutberg; [2022]
    Nyckelord :Chromium nitride; thin films; thermoelectrics; physical vapour deposition; medium entropy alloy;

    Sammanfattning : Among emerging materials systems for thermoelectric applications, the early transition-metal nitrides based on ScN and CrN show unexpectedly promising properties. These properties are determined by high Seebeck coefficient, low thermal conductivity, and high electrical conductivity. LÄS MER

  4. 3. Sensitivity Analysis and Optimization of the Vertical GSHP (Ground source heat pump)

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Sriram Ramanathan; [2020]
    Nyckelord :GSHP; Borehole heat exchanger; Geo-thermal energy.;

    Sammanfattning :   GSHP (Ground source heat pump), uses geothermal energy which is a form of green and sustainable energy.  Geothermal energy is also a continuous source of energy, unlike wind energy. The results from this thesis work will be applicable for both GSHP that are being used for space heating, and the ones which have a bottom organic Rankine cycle. LÄS MER

  5. 4. Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Ferdinand Posva; [2020]
    Nyckelord :Magnetocaloric effect; Direct method; Gadolinium; High entropy alloys;

    Sammanfattning : This project presents an attempt to construct a setup and implement a reliable technique for measuring the magnetocaloric effect (MCE) on various materials via a direct method for the acquisition of the data. The main objective of the latter is to produce a ∆Tadiabatic vs T graph over a reasonable temperature span (-100◦C up to 220◦C) by thermal monitoring of a magnetic material exposed to an oscillating magnetic field with a maximum strength of 1.

  7. 5. Heat Treatment and Secondary Phase Formation in FeCrNi Medium Entropy Alloys

    Master-uppsats, KTH/Materialvetenskap

    Författare :Amanda Carsbring; [2020]
    Nyckelord :;

    Sammanfattning : The topics of high entropy alloys (HEA) and medium entropy alloys (MEA) have been heavily researched in recent years. A HEA usually consists of five or more base elements, and a MEA would have three or four base elements. LÄS MER
