  1. 1. Automating Water Orientation in Neutron Crystallography using Convolutional Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Simon Bakran; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : One important aspect of determining the functionality of proteins is to find the direction of the dipole moment of surrounding water molecules. This is equivalent to finding the position of the hydrogen in water, however with the current atomistic model building tools this is a tedious and time-consuming task. LÄS MER

  3. 2. Computational modelling of photosynthetic excitons coupled to a microcavity

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Ilmari Turunen; [2022]
    Nyckelord :Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

    Sammanfattning : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). LÄS MER

  4. 3. Polarizability and Orientation Dynamics of Small Proteins

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Ebba Koerfer; [2022]
    Nyckelord :Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Sammanfattning : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. LÄS MER

  5. 4. Small Satellite Design for High Sensitivity Magnetic Measurements

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Noel Sebastian Janes; [2022]
    Nyckelord :Magnetic Cleanliness; FORESAIL; CubeSats; High Sensitivity Magnetic Measurements; Small Satellite;

    Sammanfattning : The magnetic cleanliness of a spacecraft during magnetic measurements is an important aspect in the design of many space science missions. The adequate reduction or removal of the spacecraft's magnetic disturbance plays a vital role in allowing the ambient magnetic field to be measured with the required accuracy. LÄS MER

  7. 5. Investigating the use of Semiconductor Nanowires for Neural Networks

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Alfredo Serafini; [2022]
    Nyckelord :FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

    Sammanfattning : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. LÄS MER
