  1. 1. Dirichlet-to-Neumann maps and Nonlinear eigenvalue problems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Tindra Jernström; Anna Öhman; [2023]
    Keywords : Dirichlet-to-Neumann maps; Nonlinear eigenvalue problems; Absorbing boundary conditions;

    Abstract : Differential equations arise frequently in modeling of physical systems, often resulting in linear eigenvalue problems. However, when dealing with large physical domains, solving such problems can be computationally expensive. READ MORE

  3. 2. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    University essay from KTH/Materialvetenskap

    Author : Gustaf Bjurstam; [2023]
    Keywords : Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Abstract : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. READ MORE

  4. 3. Introducing GA-SSNN: A Method for Optimizing Stochastic Spiking Neural Networks : Scaling the Edge User Allocation Constraint Satisfaction Problem with Enhanced Energy and Time Efficiency

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nathan Allard; [2023]
    Keywords : ;

    Abstract : As progress within Von Neumann-based computer architecture is being limited by the physical limits of transistor size, neuromorphic comuting has emerged as a promising area of research. Neuromorphic hardware tends to be substantially more power efficient by imitating the aspects of computations in networks of neurons in the brain. READ MORE

  5. 4. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  6. 5. On Russell’s Paradox and Attempted Resolutions

    University essay from Umeå universitet/Institutionen för idé- och samhällsstudier

    Author : Hannes Salin; [2023]
    Keywords : Russell’s paradox; paradoxes; set theory; sets; collections; logic;

    Abstract : This thesis explores Russell’s Paradox and the comparative analysis of Zermelo-Fraenkel set theory, von Neumann-Bernays-Gödel set theory, and Russell’s Type Theory from a mathematical Platonist perspective, focusing on the ontology of sets. Our conclusion posits that, although these theories have made significant attempts in addressing Russell’s paradox and other inconsistencies of naïve set theory, we currently lack a proper language for expressing set theory that fully captures the underlying Platonic world of sets.
