  1. 6. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Jacob Lindahl; [2023]
    Keywords : LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

    Abstract : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. READ MORE

  3. 7. Implementation and study of boundary integral operators related to PDE:s in the plane

    University essay from Lunds universitet/Matematik LTH

    Author : Erik Andersson; [2023]
    Keywords : Boundary integral equation; Singular integral operator; Product integration; Close evaluation; Numerical integration; MATLAB; Mathematics and Statistics;

    Abstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

  4. 8. Atomic Structure Calculations Using Configuration-Interaction And Many-Body Perturbation Theory For Spectral Modelling Of Neutron Star Mergers : Example Of Ce I - Iv

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Fredrik Plane; [2023]
    Keywords : Computational atomic physics; Atomic physics; Physics; Astronomy; Astrophysics; Neutron stars; Stars; Relativisitc atomic physics; Configuration-interaction; Perturbation theory; Many-body perturbation theory;

    Abstract : The binary neutron star merger of 2017 and its corresponding electromagnetic signature resembling that of a kilonova has been one of the most groundbreaking astrophysical occurrences in the last decade. Indications of r-process nucleosynthesis in this event presents new opportunities for learning about the astrophysical origin of heavy elements. READ MORE

  5. 9. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Martin Fajerberg; Mattias Nylander; [2022]
    Keywords : Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Abstract : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. READ MORE

  6. 10. Geometry Dependent Optimal Bounds of Absorption and Scattering Cross-section for Small Nanoparticles

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Md Shabbir Hossain Khan; [2022]
    Keywords : Scattering; Absorption; Nanoparticle; Cross-section; Mie; Electromagnetic; FDTD; dipole; Wavenumber.;

    Abstract : Light-matter interaction in particles of subwavelength size mostly depends on the size, shape, composition of the particles and relies on the properties of incident light. Henceforth, resonant behavior of light can be effectively controlled by changing the aforesaid geometrical parameters. READ MORE
