  1. 16. Design, implementation and evaluation of a daylight estimation tool using 3D city model data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Peter Nezval; [2021]
    Nyckelord :3D city model; CityJSON; solar energy; free and open-source software; 3D feature extraction; solar urban planning; sustainable urban development; geomatics; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Solar energy is an important component of sustainable urban development. However, it is still not reaching its full potential due to several reasons. One of them is a lack of free tools based on open geodata capable of estimating solar energy (daylight) metrics on building features, e.g. LÄS MER

  3. 17. Tyre Performance Estimation during Normal Driving

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Marcus Grip; [2021]
    Nyckelord :tyre performance; tread wear; tyre wear; online estimation; friction performance; velocity performance; friction potential; longitudinal stiffness; tyre stiffness;

    Sammanfattning : Driving with tyres not appropriate for the actual conditions can not only lead to accidents related to the tyres, but also cause detrimental effects on the environment via emission of rubber particles if the driving conditions are causing an unexpectedly high amount of tread wear. Estimating tyre performance in an online setting is therefore of interest, and the feasibility to estimate friction performance, velocity performance, and tread wear utilizing available information from the automotive grade sensors is investigated in this thesis.

  4. 18. Online graph based latency estimation of microservice applications in a FAAS environment

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Klas af Geijerstam; [2021]
    Nyckelord :;

    Sammanfattning : Function-as-a-Service (FaaS) is an increasingly common platform for many kinds of applications and services, replacing the need to maintain and setup hardware or virtual machines to host functionality in the cloud. The billing model for FaaS is commonly based on actual usage, which makes the ability to estimate the performance and latency of an application before invoking it valuable. LÄS MER

  5. 19. Online Parameter Estimation of a Six- Phase Machine for Marine Application

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

    Författare :Raimundo Montalba Mesa; [2021]
    Nyckelord :Multiphase electrical machines; IPSM; Parameter estimation; Online estimation; Stator resistance estimation; Permanent magnet flux estimation.; Flerfas elektriska maskiner; IPSM; Parameteruppskattning; Online uppskattning; Statorresistans uppskattning; Flödesuppskattning av permanentmagneter.;

    Sammanfattning : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. LÄS MER

  7. 20. Reference Tracking with Adversarial Adaptive Output- Feedback Model Predictive Control

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

    Författare :Linda Bui; [2021]
    Nyckelord :Model Predictive Control; Adversarial Multi-Armed Bandits; Kalman Filter; Output-Feedback; Adaptive Control ; Modell Prediktiv Reglering; Kontradiktoriska Flerarmade Banditer; Kalman Filter; Output-Feedback; Adaptiv Reglering;

    Sammanfattning : Model Predictive Control (MPC) is a control strategy based on optimization that handles system constraints explicitly, making it a popular feedback control method in real industrial processes. However, designing this control policy is an expensive operation since an explicit model of the process is required when re-tuning the controller. LÄS MER
