  1. 1. The black hole information paradox and holography

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Ona Mola Bertran; [2023]
    Keywords : information paradox; semiclassical physics; holography; AdS CFT correspondence; island formula; entanglement entropy;

    Abstract : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. READ MORE

  3. 2. 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

  4. 3. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Huong Nguyen; [2023]
    Keywords : Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Abstract : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

  5. 4. Optimal Gait Control of Soft Quadruped Robot by Model-based Reinforcement Learning

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Niu Xuezhi; [2023]
    Keywords : Quadruped Robots; Soft Robotics; Reinforcement Learning; Gait Control; Model-Based Control Optimization; Kvadrupedroboter; Mjukrobotik; Förstärkningsinlärning; Gångkontroll; Optimering av robotkontroll;

    Abstract : Quadruped robots offer distinct advantages in navigating challenging terrains due to their flexible and shock-absorbing characteristics. This flexibility allows them to adapt to uneven surfaces, enhancing their maneuverability. READ MORE

  6. 5. Development of a Novel Method for Automotive On-board Transmitter EMC Immunity Testing

    University essay from Uppsala universitet/Elektricitetslära

    Author : Ludvig Holm; [2023]
    Keywords : Electromagnetic Compatibility EMC ; Reverberation Chamber RC ; Vibrating Intrinsic Reverberation Chamber VIRC ; Cumulative Distribution Function CDF ; Rayleigh Distribution; Immunity testing; On-board Transmitter OBT ; Reverberating On-board Transmitter ROBT ; Expected Isotropicity; Delta-DoF; Elektromagnetisk Kompatibilitet; Modväxlande Kammare; Kumulativ Fördelningsfunktion; Rayleighfördelning; Immunitetstest; Simulerad Strålningskälla i Fordon ISO 11451-3:2015 ; Modväxlande Simulerad Strålningskälla; Förväntad Isotropicitet;

    Abstract : As the automotive industry advances through technology integration, components are designed to operate at increasingly higher frequencies. Consequently, there will be an increasing demand for automotive electromagnetic compatibility (EMC) testing. READ MORE
