  1. 1. Developing an educational tool for simulations of quantum key distribution systems

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

    Författare :Erik Åkerberg; Erik Marton Åsgrim; [2023]
    Nyckelord :;

    Sammanfattning : Quantum key distribution (QKD) is the idea of using quantum systems to securely communicate a shared encryption key between two parties. In contrast to classical methods of encryption, QKD utilizes fundamental quantum properties such as superposition and entanglement to encode information in a way that guarantees security. LÄS MER

  3. 2. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Oscar Pihl; [2023]
    Nyckelord :spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

    Sammanfattning : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

  4. 3. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sabrina Smith; [2023]
    Nyckelord :F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

    Sammanfattning : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. LÄS MER

  5. 4. Markåtkomst för ledningar i praktiken : Upplåtelseformer, prövning och tillstånd

    Kandidat-uppsats, KTH/Fastigheter och byggande

    Författare :Kayd Jama; [2022]
    Nyckelord :Land Acquisition; Land Grant; Utility Line; Utility Easement; Contractual Easement; Usufruct; Markåtkomst; markupplåtelse; ledning; ledningsrätt; avtalsservitut; nyttjanderätt;

    Sammanfattning : Markåtkomst för nybebyggelse av allmänna ledningar sker på flera olika sätt. Användning av markområdet kan säkerställs genom ett tvångsvis ägobyte med expropriation enligt expropriationslag. LÄS MER

  7. 5. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Gustav Thessén; [2022]
    Nyckelord :µ-CT modelling; phase-field method; bio-glass scaffolds; strength assessment; Mikrotomografi; μ-CT; fasfältsmetoden; bio-glas stödstrukturer; brottgräns;

    Sammanfattning : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.
