  1. 1. Quantum Annealing Algorithms for PAPR Minimisation in Wireless Networks

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :David Bern; [2022]
    Nyckelord :Quantum Mechanics; Algorithms; Quantum Annealing; Graph representation;

    Sammanfattning : In this thesis, we devise a scheme to run PAPR minimisation with 3GPP EVM requirement as constraint on the D-Wave Systems’ quantum annealer. The PAPR minimisation is a problem central to optimising the costs and performance of wireless networks becoming increasingly difficult for larger OFDM-MIMO systems, while the EVM constraint needs to be satisfied to reach an industry standard performance.

  3. 2. Optimisation of flat dielectric lenses using an interior point method

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Jonatan Ek; [2021]
    Nyckelord :Lens; Permittivity; Optimisation; Interior Point Method; Wave Propagation;

    Sammanfattning : This thesis aims to study how flat dielectric lenses can be designed. The usage of flat lenses is steadily increasing as they are smaller and less bulky than traditional convex lenses. Instead of a lens with a curved surface the permittivity in the lens is varied to achieve the same effect. LÄS MER

  4. 3. Guidance and Control for Launch and Vertical Descend of Reusable Launchers using Model Predictive Control and Convex Optimisation

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

    Författare :Guillermo Zaragoza Prous; [2020]
    Nyckelord :Model Predictive Control; RLV; Rocket; Guidance; Control; GNC; Vertical Landing; Vertical Launch; Convex Optimisation; Reusable Launcher;

    Sammanfattning : The increasing market of small and affordable space systems requires fast and reliablelaunch capabilities to cover the current and future demand. This project aims to studyand implement guidance and control schemes for vertical ascent and descent phases ofa reusable launcher. LÄS MER

  5. 4. Controller Design for Multistorey Buildings via Convex Optimisation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Emil Vladu; [2018]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Earthquakes, wind and traffic may cause unwanted vibrations in buildings. Vibration control devices are often installed between floors to suppress such disturbances. LÄS MER

  7. 5. Efficient Route-based Optimal Energy Management for Hybrid Electric Vehicles

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Simon Berntsson; Mattias Andreasson; [2018]
    Nyckelord :PHEV; HEV; energy management system; EMS; convex optimisation; ECOS; qcml; deterministic dynamic programming; DDP; ECMS; ADASIS; segmentation;

    Sammanfattning : The requirements on fuel consumption and emissions for passenger cars are getting stricter every year. This has forced the vehicle industry to look for ways to improve the performance of the driveline. LÄS MER
