  1. 6. Quadcopter Control System Design and Implementation with LQR assisted by Kalman Filter: An Experimental Study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ludwig Horvath; Martin Petré; [2023]
    Keywords : ;

    Abstract : This study stems from the audacious assumption that two bachelor students could successfully construct a functional quadcopter from scratch, covering both software and hardware aspects. The project begins by establishing a foundation for modeling the quadcopter dynamics, including derivation and linearization techniques for implementing a linear quadratic regulator (LQR). READ MORE

  3. 7. Development of thick GaN and AlGaN drift layers for vertical power devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Andri Dhora; [2023]
    Keywords : Technology and Engineering;

    Abstract : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.

  4. 8. In Search of a Method - How to Prospectively Recognise Drift into Failure

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Pieter Schaap; [2022]
    Keywords : Drift into failure; Organisational drift; Practical drift; Societal drift; Risk perception; Dynamic Risk Model; Prospectively; Retrospect; Hindsight; Foresight; Local rationale; Collective memory; FLMU06; Social Sciences;

    Abstract : The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. READ MORE

  5. 9. Electrification of Last-Mile Transport : A Study of Charging Infrastructure and Collaborative Business Model

    University essay from KTH/Energiteknik

    Author : Elin Johansson; Marcus Rostmark; [2022]
    Keywords : Electrification; electric vehicles; last-mile; charging infrastructure; risk analysis; collaborative business models; Elektrifiering; elfordon; sista milen; laddinfrastruktur; riskanalys; kollaborativ affärsmodell;

    Abstract : Electrification of the transport sector is an important step in reducing the global greenhouse gas (GHG) emissions. Compared to traditional internal combustion engine vehicles (ICEVs), electric vehicles (EVs) produce no tail-pipe emissions and could be coupled with responsible energy production from renewable energy sources to reduce coupled emissions of their operation.

  6. 10. Thermal transients study for the ESS target helium cooling system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Hannes Björk; [2022]
    Keywords : ESS; European Spallation Source; models; Modelica; system identification; sensors; cooling system; Technology and Engineering;

    Abstract : The European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. READ MORE
