  1. 1. Extremal Mechanisms for Pointwise Maximal Leakage

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

    Författare :Leonhard Grosse; [2023]
    Nyckelord :Privacy; mechanism design; information leakage; convex optimization; information-theoretic utility; Integritet; Mekanismdesign; informationsläckage; konvex optimering; informationsteoretisk användbarhet.;

    Sammanfattning : In order to implement privacy preservation for individuals, systems need to utilize privacy mechanisms that privatize sensitive data by randomization. The goal of privacy mechanism design is to find optimal tradeoffs between maximizing the utility of the privatized data while providing a strict sense of privacy defined by a chosen privacy measure.

  3. 2. Numerisk förutsägelse av markinducerade vibrationer på en byggnad

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Tommaso Meinardi; [2023]
    Nyckelord :;

    Sammanfattning : When a building is constructed close to high-speed traffic infrastructure, the assessmentof the level of vibration in those structures is relevant to guarantee safety and comfort.As long as the number of those buildings is continuously rising, is important to have amethod to evaluate ground-born vibrations that require the lower computational timepossible.

  4. 3. Underwater probe for deep sea exploration : Long range acoustic underwater communication system

    M1-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Kim Nykvist; [2020]
    Nyckelord :Acoustic communication; temperature; Expendable Bathythermograph; XBT;

    Sammanfattning : This was a thesis that was commissioned by Researcher Peter Sigray at the Royal Institute of Technology (KTH) in Stockholm and was based on an idea by Professor Thomas Rossby, University of Rhode Island (URI). The idea was to further develop the existing Expendable Bathythermograph (XBT), which has been in use since the 1960s. LÄS MER

  5. 4. Evaluation, adaption and implementations of Perfectly Matched Layers in COMSOL Multiphysics

    Master-uppsats, KTH/Numerisk analys, NA

    Nyckelord :Applied mathematics; computational mathematics; finite element method; FEM; perfectly matched layer; PML; COMSOL; Tillämpad matematik; beräkningsteknik; finita elementmetoden; FEM; PML; COMSOL;

    Sammanfattning : Perfectly matched layer (PML) is a commonly used method of absorbing waves at a computational boundary for partial differential equation (PDE) problems. In this thesis, methods for improving the usability of implementations in Comsol Multiphysics is addressed. LÄS MER

  7. 5. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

    Master-uppsats, KTH/Bro- och stålbyggnad
