  1. 1. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

    University essay from SLU/Department of Molecular Sciences

    Author : Ida Ekqvist; [2024]
    Keywords : Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

    Abstract : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

  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. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Federico Gatti; [2024]
    Keywords : Robotics; Space Engineering; Docking Maneuvers; Floating Platforms; Nonlinear MPC; MPC; Barrier function; PWM;

    Abstract : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. READ MORE

  4. 4. ENERGY CRISIS AND CLIMATE CHANGE

    University essay from Göteborgs universitet/Statsvetenskapliga institutionen

    Author : Alva Rödström; [2023-02-07]
    Keywords : Energy crisis; climate crisis; war; de-politization; fossil fuels; capitalism; renewable energy; conflict; climate activism; social movements; energy systems; sustainability;

    Abstract : The energy crisis affects households, companies and countries all over Europe. But at the same time, it is a climate crisis. The aim with this research is to understand the climate perspective’s role in the energy crisis. READ MORE

  5. 5. Data-Driven Reachability Analysis of Pedestrians Using Behavior Modes : Reducing the Conservativeness in Data-Driven Pedestrian Predictions by Incorporating Their Behavior

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

    Author : August Söderlund; [2023]
    Keywords : Data-driven reachability analysis; Autonomous vehicles; Automated safety; Autonomous situational awareness; Datadriven nåbarhetsanalys; Autonoma fordon; Automatiserad säkerhet; Autonom situationsmedvetenhet;

    Abstract : Predicting the future state occupancies of pedestrians in urban scenarios is a challenging task, especially considering that conventional methods need an explicit model of the system, hence introducing data-driven reachability analysis. Data-driven reachability analysis uses data, inherently produced by an unknown system, to perform future state predictions using sets, generally represented by zonotopes. READ MORE
