  1. 1. Evaluation of the Weather Resistance of Ram-Air Kites Used in Airborne Wind Energy Systems

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

    Författare :Johanna Désirée Ambs; [2023]
    Nyckelord :Weathering Resistance; Coated Textiles; Ram-air Kite; Airborne Wind Energy;

    Sammanfattning : Airborne Wind Energy is an emerging technology that harnesses the power of the wind by using tethered wings. Among the flying devices are ram-air wings made from coated textiles that utilize dynamic pressure to gain their shape. LÄS MER

  3. 2. Nyttan med träfasader : en litteraturstudie avseende brandbeständighet, hållbarhet och miljöpåverkan

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Oskar Grönlund; Alexander Winroth; [2020]
    Nyckelord :Brand; Träfasad; Beständighet; Urlakning;

    Sammanfattning : This bachelor thesis has been performed as a literature study and consists of pros and cons considering test methods, sustainability, cost efficiency, legislation and environmental effects of flame-retardant wooden façades. The study also handles the possible consequences from the lack of permanency of the flame retardants in wooden façades due to leaching. LÄS MER

  4. 3. Evaluation of DC resistivity and time-domain IP tomography for bedrock characterisation at Önneslöv, Southern Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Daniel Preis Bergdahl; [2016]
    Nyckelord :bedrock; Cole-Cole; resistivity; induced polarization; dyke; weathering; Earth and Environmental Sciences;

    Sammanfattning : For both construction and exploration purposes, knowledge of the subsurface is important. Geophysical exploration methods can be used to acquire an overview of an area on which further investigations can be based. LÄS MER

  5. 4. The Role of Misconceptions in the Development of a Reliable Geological Knowledge. A Statistical Analysis of the Alternative Ideas of Earth Science Bachelor Students at Uppsala University.

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Despoina Chouliara; [2016]
    Nyckelord :Misconceptions; alternative ideas; earth sciences; Missuppfattningar; alternativa idéer; geovetenska;

    Sammanfattning : The pre-existing knowledge that Earth Science Bachelor students have when they are starting their University studies, is influential on the scientific knowledge that they will have built when they graduate. This thesis examines the alternative ideas that Uppsala University’s first, second and third year Earth Science Bachelor students have on basic geological topics, and whether it influences the knowledge that they develop.

  7. 5. Surface Studies on Industrial Aluminium Alloys

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Lisa Rullik; [2014]
    Nyckelord :aluminium alloy; heat treatment; XPS; XPEEM; Physics and Astronomy;

    Sammanfattning : Aluminium alloys are used in a wide range of applications due to their high tensile strength concomitant with low density. Additionally, aluminium alloys form a naturally occurring and passivating oxide layer, which leads to high corrosion and weathering resistance. LÄS MER
