  1. 1. Weight Optimization of Vertical-Axis Wind Turbine Blades constructed in Swedish Fossil Free Steel : With respect to fatigue life time

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Johannes Hall; Albin Larsson; [2023]
    Keywords : VAWT; Wind Turbine Blade; SSAB; Fossil-Free; Weight Optimization; Topology Optimization; Sizing Optimization; NACA 0018; STRENX 1300; Abaqus; Tosca Structure; VAWT; Vindturbinblad; SSAB; Fossilfritt; Viktoptimering; Topologioptimering; Size-Optimering; NACA 0018; STRENX 1300; Abaqus; Tosca Structure;

    Abstract : Wind turbines have been utilized for centuries to harness energy from the wind. Commercial wind turbine blades are typically made from composite materials, which are difficult to recycle, leading to blades ending up in landfills at the end of their lifecycle. Additionally, these materials contribute to microplastic pollution. READ MORE

  3. 2. Skogsprodukter som idisslarfoder vid bristsituationer med fokus på mjölkkor

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Milton; [2020]
    Keywords : skogsprodukter; skogsråvaror; smältbarhet; grovfoder; idisslare; mjölkkor; mjölkavkastning; förbehandling; processteknik;

    Abstract : Träd innehåller cellulosa och hemicellulosa, vilket idisslare kan bryta ned och utvinna energi ifrån. Skogsprodukter/skogsråvaror så som träflis, spån, bark och pappersmassa har därför god potential till att fungera som grovfoder för idisslare. READ MORE

  4. 3. A study on the effects on a wastewater treatment plant when recovering the heat from the wastewater

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

    Author : SUSANNE BERGSTRAND; [2020]
    Keywords : ;

    Abstract : source of thermal energy. Wastewater as a source of energy has gotten more attention in recent times, as the Sustainable Development Goals in combination with local challenges encourage new technical solutions that can replace old and outdated technology. READ MORE

  5. 4. Poly(p-terphenyl piperidinium) as anion exchange membranes. Synthesis and evaluation of properties

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hugo Selling; [2020]
    Keywords : Fuel cells; Alkaline exchange membrane fuel cells; Anion exchange membrane fuel cells; Polymer technology; Polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Alkaline exchange membrane fuel cells (AEMFC) is an interesting and attractive alternative to proton exchange membrane fuel cells (PEMFC) due to the potential use of non-precious catalysts which can reduce the overall cost of the fuel cell. An important component of the AEMFC is the anion conducting membrane. READ MORE

  6. 5. Energy harvesting from ambient WiFi energy : A method of harvesting and measuring ambient WiFi energy

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

    Author : Alpha Fofana; Carl Mossberg; [2019]
    Keywords : Energy harvesting; Rectenna; Impedance matching; Embedded system; IoT; WiFi; Sustainable Energy; Utvinna energi; Impedansmatchning; Inbyggda system; IoT; WiFi; Hållbar utveckling;

    Abstract : The aim of this thesis was to investigate the question of how to harvest RF energy and if we can harvest enough RF energy for it to be useful in an application. It is aimed towards sensor node applications, commonly used in a typical office environment. The WiFi band was chosen since it is omnipresent in the same environment. READ MORE
