  1. 16. The Deployable Wing Structure for the KTH REXUS Free Falling Unit

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jennifer Ly; Orgil Jargalsaikhan; [2021]
    Nyckelord :Deployment; Deployable Structure; Scissor Structural Mechanism; Glider; REXUS BEXUS;

    Sammanfattning : With the help of sounding rockets, the Earth’sionosphere can be studied by ejecting cylindrical units thatmeasure various electromagnetic properties while falling. Theseunits are also known as Free Falling Units (FFUs). The goal of thisproject is to turn the FFUs into autonomous gliders by designingdeployable wings. LÄS MER

  3. 17. Cooling Strategy Influence on Temperature in ETD Center

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

    Författare :Oskar Edinger; [2021]
    Nyckelord :Machining; Drilling; Exchangeable tip drill; 316L Stainless steel; Thermocouple; IR Thermography; Skärande bearbetning; Borrning; Löstoppsborr; 316L Rostfritt stål; Termoelement; IR Termografi;

    Sammanfattning : Striving for increased productivity while maintaining hole quality and high process robustness when drilling requires knowledge about the working principles of heat generation, mechanics and a proper cutting fluid that aids in cooling, lubricating and evacuating chips from the cutting zone. If the heat generated in the tool-workpiece and tool-chip interfaces does not exit the cutting zone adequately through the chips, the workpiece material or the redistribution of coolant the hole quality can be impacted negatively and breakdowns may occur which reduces overall productivity.

  4. 18. Design Automation of Steam Turbine Diaphragms in NX : Research and implementation of design automation in a development process

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Emil Tellsén; [2021]
    Nyckelord :Design automation; CAD; Process development; Knowledge based engineering; NX;

    Sammanfattning : Siemens Energy develops, manufactures, and provides service of products utilized for production of green energy. This thesis has been conducted at Siemens Energy in Finspång and the department of steam turbine design. A major part of the work at the department includes service and updates of operating steam turbines located all around the world. LÄS MER

  5. 19. Convolutional neural networks for semantic segmentation of FIB-SEM volumetric image data

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Fredrik Skärberg; [2020-11-26]
    Nyckelord :Deep learning; convolutional neural networks; image analysis; semantic segmentation; focused ion beam scanning electron microscopy; porous materials; controlled drug release;

    Sammanfattning : Focused ion beam scanning electron microscopy (FIB-SEM) is a well-established microscopy technique for 3D imaging of porous materials. We investigate three porous samples of ethyl cellulose microporous films made from ethyl cellulose and hydroxypropyl cellulose (EC/HPC) polymer blends. LÄS MER

  7. 20. Conceptual design and construction of a UAV wing structure

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Selma Rahman; Anujan Ranganathan; [2020]
    Nyckelord :;

    Sammanfattning : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. LÄS MER
