  1. 1. Reevaluating the Notion of Peace : Do Our Current Measurements Truly Reflect Peace?

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Sanna Besic; [2024]
    Keywords : Peace Measuring; Peace Studies; Peace Conceptualisation; Peace Measurements; Violence; Direct Violence; Structural Violence; Cultural Violence;

    Abstract : There is an ongoing theme within the field of peace conceptualisation to create and to add to the meaning of peace. This has caused a fragmented field with over 130 conceptualisations. As we move forward, it isthus necessary to review whether the methods utilised to measure peace are suitable in the ever changing contexts of today. READ MORE

  3. 2. Holistic Assessment of Critical Infrastructure Resilience during Disasters (HACIRD) - A case study of the 2023 Kahramanmaras earthquakes

    University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Erik Kimblad; [2024]
    Keywords : Critical infrastructure; Lifeline; Resilience; Interdependencies; Earthquake; Natural hazards; Turkey; Holistic; Disaster; Framework; Assessment; Empirical; Case study; Technology and Engineering;

    Abstract : On February 6, 2023, two earthquakes (7.8MW and 7.7MW) struck Turkey within nine hours, resulting in over 50,000 fatalities and significant damage to critical infrastructures (CI) which provide services essential for the functioning of society. READ MORE

  4. 3. 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.

  5. 4. Techno-Economic Analysis of Dye Separation in Textile Recycling

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : David Lundberg; [2024]
    Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

  6. 5. 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
