  1. 6. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

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

    Författare :Simon Pääjärvi; [2022]
    Nyckelord :Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Sammanfattning : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. LÄS MER

  3. 7. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Wassim Wahbeh; Youssef Hasan; [2022]
    Nyckelord :DARDS;

    Sammanfattning : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. LÄS MER

  4. 8. Renovations and Energy Planning : An energy performance and economics analysis in 3D-modelling

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Hampus Selin; Karl Hjortenholt; [2022]
    Nyckelord :BIM Energy; Energy efficiency; Energy modelling; Energy performance; LCC; Renovation;

    Sammanfattning : This thesis examines the opportunities towards streamlining energy efficiency in the existing built environment in Sweden. Through this case study, the aim has been to optimise two 20th century buildings, one apartment building and one workshop building, located at different latitudes in the country. LÄS MER

  5. 9. Adoption of Additive Manufacturing in the Medical Industry within Sweden : Stakeholder analysis in the process of adoption of AM in the medical industry and their influence on each other

    Master-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

    Författare :Sairaj Parasa; Mohammed Abujan Rehman Basha; [2021]
    Nyckelord :Additive manufacturing; stakeholders’; stakeholder analysis; adoption of new technology; medical industry.;

    Sammanfattning : Additive manufacturing (AM) is a printing technology which can produce 3-dimensional solid object by adding layers of material from 3D model data. AM has numerous benefits and can bring a new industrial revolution. To have a smooth transition in the technology, organizations must consider involved stakeholders’ interests. LÄS MER

  7. 10. Multicolor 3D printing : An analysis of the characteristics of multicolor 3Dprinting

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Davron Patkhullaev; Yonas Melake; [2021]
    Nyckelord :Mechatronics; 3D printer; Arduino Mega; Diamond Hotend; Marlin; Mekatronik; 3D printer; Arduino Mega; Diamond Hotend; Marlin;

    Sammanfattning : 3D printing has risen in popularity due to its capabilities which enable rapid prototyping and printing structures that were impossible to produce before and partially because of technological development in recent years. Most low-cost printers, based on the fused filament fabrication process, are capable of printing a single filament at a time that limits and complicates multicolor and multi-material 3D printing.
