  1. 11. On quantum systems and the measurement problem

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Nicolas Boulle; [2023]
    Nyckelord :Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

    Sammanfattning : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. LÄS MER

  2. 12. A Conjugate Residual Solver with Kernel Fusion for massive MIMO Detection

    Master-uppsats, Högskolan i Halmstad/Centrum för forskning om tillämpade intelligenta system (CAISR)

    Författare :Ioannis Broumas; [2023]
    Nyckelord :MIMO; massive MIMO; GPU; CUDA; Software Defined Radio; SDR; MMSE; ZF; zero-forcing; parallel detection; iterative methods; conjugate residual; parallel computing; kernel fusion;

    Sammanfattning : This thesis presents a comparison of a GPU implementation of the Conjugate Residual method as a sequence of generic library kernels against implementations ofthe method with custom kernels to expose the performance gains of a keyoptimization strategy, kernel fusion, for memory-bound operations which is to makeefficient reuse of the processed data. For massive MIMO the iterative solver is to be employed at the linear detection stageto overcome the computational bottleneck of the matrix inversion required in theequalization process, which is 𝒪(𝑛3) for direct solvers.

  3. 13. KEY PERFORMANCE INDICATORS TO INCREASE LOGISTICS PERFORMANCE IN THE DAIRY INDUSTRY : A CASE STUDY IN THE DAIRY INDUSTRY

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Tor Shimamura Fagle; [2023]
    Nyckelord :Supply Chain; Supply Chain Management; Logistics Performance; Inventory Management; Performance Measure; Performance Measurement System; Key Performance Indicator; MICMAC; Self-Structured Interaction Matrix; Food Supply Chains; Dairy Industry.; Försörjningskedja; Försörjningskedjehantering; Logistikprestanda; Lagerhantering; Prestationsmått; Prestationsmätningssystem; Nyckelprestandaindikator; MICMAC; Självstrukturerad interaktionsmatris; Livsmedelskedja; Mejeriindustri.;

    Sammanfattning : The dairy industry is a complex system that involves many stakeholders and processes, from production to distribution. To measure and improve the performance of this system, a comprehensive and reliable Performance Measurement System (PMS) is needed. A PMS is a tool that helps to evaluate the efficiency and effectiveness of supply chain operations. LÄS MER

  4. 14. Fallstudie om hantering av transportrelaterade kvalitetsbrister : En fallstudie på ett möbeltillverkande företag

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Adam Fredén; Marcus Svanström; [2023]
    Nyckelord :Transportskador; hanteringskador; kvalitetsbrister; offensiv kvalitetsutveckling; hörnstensmodellen;

    Sammanfattning : Företag X är en organisation som värderar kvalitet högt. Detta företag tillverkar möbler med sin utgångspunkt i Sverige. Inom svensk industri uppskattas kvalitetsbristkostnader stå för 10–30 % av omsättningen. LÄS MER
