  1. 21. Hyperbolic fillings of bounded metric spaces

    University essay from Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Author : Ludvig Fagrell; [2023]
    Keywords : biLipschitz equivalent; Gromov hyperbolic space; hyperbolic filling; metric space; snowflake-equivalent;

    Abstract : The aim of this thesis is to expand on parts of the work of Björn–Björn–Shanmugalingam [2] and in particular on the construction and properties of hyperbolic fillings of nonempty bounded metric spaces. In light of [2], we introduce two new parameters λ and ξ to the construction while relaxing a specific maximal-condition. READ MORE

  3. 22. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Gustav Blomgren; Ebba Carlsson; [2023]
    Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

    Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

  4. 23. Probing Strangeness Production in Proton-Proton Collisions with Three-Particle Correlations

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

    Author : Melinda Petricean; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Strangeness production in small systems such as proton-proton collisions is here investigated through the use of three-particle correlations in the momentum-space coordinates η and ϕ. This method is used in order to investigate possible correlation between conservation of both strangeness and baryon number, such that the particles chosen are Λ¯pK+ and the respective charge conjugates, where Λ is a strange baryon, p¯ balances: the Balance Function and the comparative restriction of relative positions for pairs of particles within given triplets.

  5. 24. Arbitrary motion Synthetic Aperture Radar

    University essay from Lunds universitet/Matematisk statistik

    Author : Filip Alberius; Erik Rolander; [2023]
    Keywords : RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Abstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

  6. 25. A Multi-Level Extension of the Hierarchical PCA Framework with Applications to Portfolio Construction with Futures Contracts

    University essay from KTH/Matematisk statistik

    Author : Kajsa Bjelle; [2023]
    Keywords : Portfolio construction; asset allocation; principal component analysis; hierarchical principal component analysis; hierarchical shrinkage; eigenportfolio risk; Portföljkonstruktion; tillgångsallokering; principalkomponentanalys; hierarkisk principalkomponentanalys; hierarkisk krympning; egenportföljrisk;

    Abstract : With an increasingly globalised market and growing asset universe, estimating the market covariance matrix becomes even more challenging. In recent years, there has been an extensive development of methods aimed at mitigating these issues. READ MORE
