  1. 1. Gromov-Witten invariants via localization techniques

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Noah Dizep; [2023]
    Keywords : Gromov-Witten invariants; enumerative geometry; string theory;

    Abstract : Gromov-Witten invariants play a crucial role in symplectic- and enumerative Geometry as well as topological String Theory. Essentially, theseinvariants are a count of (pseudo)holomorphic curves of a given genus,going through n-marked points on a symplectic manifold. READ MORE

  3. 2. Hierarchical Fusion Approaches for Enhancing Multimodal Emotion Recognition in Dialogue-Based Systems : A Systematic Study of Multimodal Emotion Recognition Fusion Strategy

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

    Author : Yuqi Liu; [2023]
    Keywords : Multimodal; emotion recognition; hierarchical fusion; context modeling; attention mechanism; feature-level fusion; decision-level fusion; machine learning; deep learning; Multimodal; emotion recognition; hierarkisk fusion; kontextmodellering; uppmärksamhetsmekanism; funktionssammanfogning på nivån för egenskaper; beslutsnivås-funktionssammanfogning; maskininlärning; djupinlärning;

    Abstract : Multimodal Emotion Recognition (MER) has gained increasing attention due to its exceptional performance. In this thesis, we evaluate feature-level fusion, decision-level fusion, and two proposed hierarchical fusion methods for MER systems using a dialogue-based dataset. READ MORE

  4. 3. Increasing Trust in Software by Synthesizing Property-based Tests from Existing Unit Tests : A study on the expansion of existing test suites through the creation of property-based tests via invariants inferred from existing example-based unit tests

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

    Author : Richard Uggelberg; [2022]
    Keywords : Software Testing; Software Engineering; Test Improvement; Property-based Testing; Invariant Detection; Mjukvarutestning; Mjukvarukonstruktion; Testförbättring; Egenskapsbaserad Testning; Invariantdetektion;

    Abstract : Many software projects include an extensive suite of example-based unit tests. The examples in the test suite can be used as an implicit specification of the behavior of the software. Inferring invariants from these examples may aid in the creation of property-based tests. READ MORE

  5. 4. Exploring persistent homology as a method for capturing functional connectivity differences in Parkinson’s Disease.

    University essay from KTH/Matematik (Avd.)

    Author : Naomi Hulst; [2022]
    Keywords : persistent homology; topological data analysis; computational topology; parkinson s disease; parkinson; functional connectivity; stable rank; ihållande homologi; topologisk data analys; beräknings topologi; Parkinsons sjukdom; parkinson; funktionell konnektivitet; stable ranks;

    Abstract : Parkinson’s Disease (PD) is the fastest growing neurodegenerative disease, currently affecting two to three percent of the population over 65. Studying functional connectivity (FC) in PD patients may provide new insights into how the disease alters brain organization in different subjects. READ MORE

  6. 5. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Sparrman; [2022]
    Keywords : Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

    Abstract : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. READ MORE
