  1. 1. Control Barrier Functions for Formation Control of Leader-follower Multi-agent Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tianrun Sun; [2023]
    Nyckelord :Multi-agent System; Leader-follower System; Formation Control; Control Barrier Function; Connectivity Maintenance; Multi-agent-system; Leader-follower-system; Formations Kontroll; Kontroll Barriär Funktion; Underhåll av Anslutningsmöjligheter;

    Sammanfattning : This thesis studies formation control for a class of general leader-follower multi-agent systems with Control Barrier Functions (CBFs) such that connectivity maintenance is fulfilled for all the neighboring agents. In leader-follower multi-agent systems, only the leader agents are controlled by the externally designed input, while the followers are guided through their dynamic couplings with the neighboring agents.

  3. 2. Jet fragmentation in shaped charges

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Joakim Ericson; [2022]
    Nyckelord :Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Sammanfattning : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. LÄS MER

  4. 3. Exact eigenstates of the Inozemtsev spin chain

    Master-uppsats, KTH/Fysik

    Författare :Simon Lentz; [2021]
    Nyckelord :Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Sammanfattning : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. LÄS MER

  5. 4. Searching for signatures of compositeness of the Higgs boson

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Mårten Bertenstam; [2021]
    Nyckelord :two-Higgs-doublet model; composite Higgs model; composite two-Higgs-doublet model; phase transition; cosmological phase transition; electroweak phase transition; gravitational waves; gravitational wave background; Physics and Astronomy;

    Sammanfattning : In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. LÄS MER

  7. 5. Comparison of Second Order Optimization Algorithms in Neural Networks Applied on Large-Scale Problems

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Johanna Frost; Rafael Lavatt; [2020]
    Nyckelord :;

    Sammanfattning : This bachelor thesis compares the second order optimization algorithms K-FAC and L-BFGS to common ones of firstorder, Gradient Descent, Stochastic Gradient Descent, and Adam, applied on neural networks for image classification. Networks with different architecture and number of parameters have been implemented and tested on three different data sets of images. LÄS MER
