  1. 1. Benchmarking linear-algebra algorithms on CPU- and FPGA-based platforms

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

    Författare :Omar Askar Vergara; Karl Törnblom Bartholf; [2023]
    Nyckelord :FPGA; OpenCL; PolyBench; Cholesky; Durbin;

    Sammanfattning : Moore’s law is the main driving factor behind the rapid evolution of computers that has been observed in the past 50 years. Though the law is soon ending due to heat- and sizing-related issues. One solution to continuing the evolution is utilizing alternative computer hardware, where parallel hardware is especially interesting. LÄS MER

  3. 2. Acceleration of Massive MIMO algorithms for Beyond 5G Baseband processing

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ellen Nihl; Eek de Bruijckere; [2023]
    Nyckelord :embedded systems; massive MIMO; GPU; massive MIMO detection; Zero-Forcing algorithm; Cholesky decomposition; CUDA; 5G and Beyond;

    Sammanfattning : As the world becomes more globalised, user equipment such as smartphones and Internet of Things devices require increasingly more data, which increases the demand for wireless data traffic. Hence, the acceleration of next-generational networks (5G and beyond) focuses mainly on increasing the bitrate and decreasing the latency. LÄS MER

  4. 3. Houses, we have a problem!

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :David Grahn; Stefania Mammos; [2021]
    Nyckelord :Unconventional monetary policy; House prices; BSVAR; Cholesky decomposition; Zero and sign restrictions; Business and Economics;

    Sammanfattning : This thesis investigated how expansionary unconventional monetary policies affect house prices in the Scandinavian countries, using quarterly data from 1995 to 2020. Unconventional monetary policy, such as quantitative easing and forward guidance, has become widely used by central banks, in order to stimulate the economy when being in a zero lower bound environment.

  5. 4. IRRBB in a Low Interest Rate Environment

    Master-uppsats, KTH/Matematisk statistik

    Författare :Simon Berg; Victor Elfström; [2020]
    Nyckelord :IRRBB; Gap Risk; Basis Risk; Option risk; Interest rate; Yield Curve; Nelson Siegel Svensson; PCA; Cholesky Decomposition; EBA; EVE; NII; Risk; Interest rate risk; IRRBB; Gaprisk; Basrisk; Optionsrisk; Ränta; Avkastningskurva; Nelson Siegel Svensson; PCA; Cholesky Decomposition; EBA; EVE; NII; Risk; Ränterisk;

    Sammanfattning : Financial institutions are exposed to several different types of risk. One of the risks that can have a significant impact is the interest rate risk in the bank book (IRRBB). In 2018, the European Banking Authority (EBA) released a regulation on IRRBB to ensure that institutions make adequate risk calculations. LÄS MER

  7. 5. Fast Real-Time MPC for Fighter Aircraft

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Amanda Andersson; Elin Näsholm; [2018]
    Nyckelord :MPC; fast MPC; explicit MPC; fighter; aircraft; neural network; model predictive control; interior-point method;

    Sammanfattning : The main topic of this thesis is model predictive control (MPC) of an unstable fighter aircraft. When flying it is important to be able to reach, but not exceed the aircraft limitations and to consider the physical boundaries on the control signals. LÄS MER
