  1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Shivang Parmar; [2023]
    Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER

  3. 2. Skildring och analys av livets mening i manga : Tematisk litteraturanalys av temat livets mening i mangaserien Solanin av Inio Asano

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för humaniora och samhällsvetenskap

    Författare :Frank Lundberg; [2022]
    Nyckelord :Inio Asano; Solanin; manga; multimodality; mode; semiotic resource; image; text; theme; education;

    Sammanfattning : The purpose of this essay is to thematically analyse the manga Solanin by Inio Asano and discuss the suitability of using the work in an educational context. As manga is a format that employs both image and text to create meaning, the essay analyses Solanin through a multimodal lens with a focus on the terms mode and semiotic resource to observe and discuss how image and text interface with each other to depict the work’s theme.

  4. 3. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Emil Treitler; [2022]
    Nyckelord :Fatigue; Kaplan; Hydropower; Turbine;

    Sammanfattning : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. LÄS MER

  5. 4. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  7. 5. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Bakhtiar Afzalan; [2021]
    Nyckelord :Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

    Sammanfattning : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. LÄS MER
