  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  3. 2. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  4. 3. Major Component Replacement on Floating Wind Turbines

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

    Author : Kilian Galle; [2023]
    Keywords : ;

    Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE

  5. 4. Assessing Textile Raw Materials and Exploring Sustainable Sources for Future Renewable Textile Materials for IKEA of Sweden

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Keywords : drought; water scarcity; land degradation; cotton Gossypium sp. ; synthetic textiles; viscose; lyocell; IKEA; agro-waste; poplar Populus sp. ; bamboo Bambusoideae ; sustainability;

    Abstract : This degree project at the Swedish University of Agricultural Sciences has been conducted in collaboration with IKEA of Sweden. The textile industry contributes to significant environmental challenges, including pollution and global water scarcity. READ MORE

  6. 5. Evaluating the impact of agriculture on albedo using Sentinel-2 data in southern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Victor Andréasson; [2023]
    Keywords : Physical geography and ecosystem science; Remote sensing; Sentinel-2; Albedo; Agriculture; Earth and Environmental Sciences;

    Abstract : The climate impact of food production plays a big part in the anthropogenic climate impact. Mitigation strategies from this sector are hence of great importance. One area which mainly has been used to calculate climate impact is albedo, the overall reflectance of incoming radiation in all directions. READ MORE
