  1. 1. Exocomets in the β Pictoris system

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Klaudia Jaworska; [2024]
    Keywords : Physics and Astronomy;

    Abstract : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. READ MORE

  2. 2. FPGA Based Control of Multiple Electric Machines for Marine Propulsion Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Weideskog; [2024]
    Keywords : FPGA; Field Oriented Control; BLDC; SVPWM; SMO; Electric Drives; Electric Machines; Sliding Mode Observer; Marine Propulsion; Multiple Machines; Boat Motor; Fältorienterad styrning; marin framdrivning; elektriska drivsystem; elmaskiner; flertal maskiner; båtmotor;

    Abstract : This master thesis addresses the control of electric propulsion motors in a marine context. The focus lies mainly on the implementation of field oriented control (FOC) in a field programmable gate array (FPGA). The hypothesis is that FPGAs provide performance advantages over microcontroller-based control solutions by enabling parallel processing. READ MORE

  3. 3. Local voltage control in a low voltage grid with high photovoltaic penetration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Joakim Bakklund; [2024]
    Keywords : Technology and Engineering;

    Abstract : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. READ MORE

  4. 4. FE-Modelling of Composite Girder tests

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Holger Berggren; Bergstedt Ola; [2024]
    Keywords : shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Abstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE

  5. 5. A Comparative Investigation of Classical Random and Quantum Walks in Terms of Algorithms, Implementation, and Characteristics

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Naoki Moriya; [2024]
    Keywords : Qunatum computing; quantum walk;

    Abstract : In recent years, there has been a significant development in high performance computing, driven by advances in hardware and software technology. The performance of the computers to the present has improved in accordance with Moore’s law, on the other hand, it seems to be reaching the limits in the near future. READ MORE
