  1. 11. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Lone Mokkenstorm; [2021]
    Nyckelord :Physical Geography; Ecosystem Analysis; Early Warning; Riverine Floods; Humanitarian Work; Impact-based Forecasting; Malawi; Earth and Environmental Sciences;

    Sammanfattning : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.

    Sammanfattning : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. LÄS MER

  4. 13. Evaluation of Active Rear Steering through Multi-Body Simulation

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Matteo Rossi; Gabriele Bertoli; [2021]
    Nyckelord :Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Sammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

  5. 14. Pensionssparares syn på hållbara investeringar : En studie om premiepensionssparares respons till Morningstars Hållbarhetsbetyg

    Master-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakulteten

    Författare :Rebecka Gärderup; Thea Nguyen; [2021]
    Nyckelord :Swedish Pensions Agency; Morningstar Sustainability Rating; mutual funds; sustainable investments; Pensionsmyndigheten; premiepension; Morningstars hållbarhetsbetyg; fonder; hållbara investeringar;

    Sammanfattning : Det finns både växande intresse och uppmuntran till att investera kapital ansvarsfullt för att bidra till hållbar utveckling. Morningstar är en av flertalet aktörer som erbjuder extern värdering av fonders hållbarhetsprestation i syfte att förse investerare med objektiv bedömning. LÄS MER

  7. 15. Consumer responsibilization in sustainable fashion communications on Instagram : A multimodal discourse analysis

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Vera Sofie Thallinger; Lusanda Ntintili; [2021]
    Nyckelord :Instagram; Social Media; Multimodal Discourse; Consumer Responsibilization; Sustainable Fashion; Cultural Marketing;

    Sammanfattning : Background, Problem Statement and Gap - Political agendas informed by the negative impacts of increasing consumption (including fashion consumption) have allocated major parts of the responsibility to contribute to sustainable development to individual consumers. These agendas subsequently highlighted the need to provide more information, including through media and social media, about the negative impacts of fashion consumption - and consumption at large - to the consumer.
