  1. 1. 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. 2. Feasibility Study of Energy Harvesting via Biofuel Cell for Miniaturised Implantable Biosensors

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Rebecca Bonato; [2024]
    Keywords : Biofuel cell; Blood; Energy Harvesting; Glucose; Power Density; Oxygen;

    Abstract : In the current pursuit of sustainable energy, biofuel cells are attracting considerable attention. Within biomedical engineering, the concept of harnessing energy from biological fluids, such as blood, holds significant promise, enabling both full autonomy and miniaturization. READ MORE

  4. 3. GREEN CITY ZONE A Case-Study in a Multi-Stakeholder Initiative within a Smart City

    University essay from Institutionen för tillämpad informationsteknologi

    Author : Florin Gabriel Dascalu; Nicole Dawn DiNatali; [2023-02-01]
    Keywords : net-zero emissions; multiple stakeholder management; construal level; temporal distance; system thinking; sociotechnical system theory; project management; smart city;

    Abstract : As climate change concerns have taken a central spot in mainstream discourse, there has been an emergence of green smart city projects, resulting in an increased demand for research in these areas. As the EU has pledged a reduction of emissions, various projects have arisen, such as Climate Contract 2030, Move21, and this thesis’ subject – the Gothenburg Green City Zone. READ MORE

  5. 4. Effect of Trace Elements on the Particle Size of Magnesium Silicide in Aluminium Extrusion : The Use of Thermo-Calc and DICTRA in order to Produce Aluminium more Efficiently

    University essay from KTH/Materialvetenskap

    Author : Gustav Boustedt; Johan Alexander Valentin Nygren; Gustav Strandgård; [2023]
    Keywords : Thermo-Calc; DICTRA; simulations; EN AW 6082; extrusion; particle precipitation; Mg2Si; sustainable; trace elements; aluminium;

    Abstract : This project is a feasibility study for Hydro Extrusion Sweden AB, a company that produces extruded aluminium profiles. The main purpose of this project was to analyse the difference of Mg2Si particle sizes in aluminium alloys when varying parameters, such as cooling rate and composition, in aluminium extrusion, particularly the EN AW 6082 alloy.

  6. 5. Accelerating university-industry collaborations with MLOps : A case study about the cooperation of Aimo and the Linnaeus University

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Nico Pistor; [2023]
    Keywords : MLOps; Machine Learning Operations; Development Process; Machine Learning; Artificial Intelligence; DevOps; Collaboration;

    Abstract : Many developed machine learning models are not used in production applications as several challenges must be solved to develop and deploy ML models. Manual reimplementation and heterogeneous environments increase the effort required to develop an ML model or improve an existing one, considerably slowing down the overall process. READ MORE
