  1. 1. Using Artificial Neural Networks to optimize scattering probabilities

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Erik Rustas; [2021]
    Keywords : Machine Learning; Artificial Neural Network; Monte Carlo Method; Unweighting; Physics and Astronomy;

    Abstract : Monte Carlo event generators are used by theoretical particle physicists to get a better understanding of the phenomena in particle physics. Given the improvements in precision and accuracy of event generators, using these tools can be very CPU intensive. READ MORE

  3. 2. Weather Influence on LiDAR Signals using the Transient Radiative Transfer and LiDAR Equations

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

    Author : Marcus Hedlund; [2020]
    Keywords : Radiative transfer; LiDAR; Transient radiative transfer;

    Abstract : The ongoing development of self driving cars requires accurate measuring devices and the objective of this thesis was to investigate how di↵erent weather will affect one of these devices, known as a LiDAR. A LiDAR uses pulsed laser light to measure the distance to an object. READ MORE

  4. 3. The double-copy method for supergravity amplitudes

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Maor Ben-Shahar; [2019]
    Keywords : Supergravity; quantum field theory; counterterm; amplitudes;

    Abstract : The double-copy construction enables the calculation of scattering amplitudes in theories of gravity by combining amplitudes from gauge theories. It relies on obtaining numerators that obey a duality between color and numerator factors, called color-kinematics duality. READ MORE

  5. 4. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Maitane Muñoz Basagoiti; [2019]
    Keywords : quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Abstract : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.

  6. 5. Dissolution and fibre spinning of cellulose from an ionic liquid

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Erika Andersson; [2018]
    Keywords : Cellulose; scattering; ionic liquid; dissolution; regenerated cellulose fibre; structure-property relationship; materials chemistry; materialkemi; Chemistry; Technology and Engineering;

    Abstract : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. READ MORE
