  1. 16. Framställning av dränerande bärlager från bergtäkt

    M1-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Iyad Abu Sulaiman; Miran Ibrahim; [2023]
    Nyckelord :Dränerande; bärlager; 0 32; bergtäkt; Digiroad; NCC; filler; harpa; harpsiktning; sikt; skopa; bergmaterial; 8 90; AMA 23; anläggning; trafikverket; restprodukt; översvämning; galler; modell; siktduk; finmaterial; simulering; väg; marklager;

    Sammanfattning : Bearing layers are used in road and building constructions as underlying soil layers to provide stability and support to the top layer that takes up the load. A normal bearing layer contains different amounts of materials such as stone, gravel, and filler. LÄS MER

  3. 17. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Morgan Agerstig Rosenqvist; [2023]
    Nyckelord :Radar; FMCW; micro-Doppler; RPM;

    Sammanfattning : Micro-Doppler effects are phenomena that occur because of micro-motion. A micro-motion is either a vibration, rotation, or acceleration which is small relative to the motion of the target. These effects can be used in order to characterize a target through their signature movement. LÄS MER

  4. 18. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products

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

    Författare :Julia Svensson; Hanna Halldorf; [2023]
    Nyckelord :Spacer fabric; knitting; warp knit; circular knit; textile testing; ProCad Warpknit; infant product; comfort; mechanical properties.;

    Sammanfattning : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.

  5. 19. Machine Condition Monitoring of Production Equipment

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Alexander Olsson; Henrik Persson Caesar; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This study investigates the possibility of implementing a machine monitoring system on IBAS2, a production machine responsible for aligning an optical lens with an image sensor. A machine-monitoring system could possibly reduce downtime, costs, and production recalls. LÄS MER

  7. 20. Knowledge-Based Engineering Application For Fuselage Integration And Cabin Design

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Nikhil Bhargav; Vasanth Elangovan; [2023]
    Nyckelord :Commercial aircraft; Liquid Hydrogen; Cabin Design; LH2 Tank Integration; Sustainability; Knowledge Based Engineering; Tank Integration; Web Based Application;

    Sammanfattning : The pace of development in aviation technology is increasing, and there is a constantneed for new concepts to keep up. An innovative concept is desired to reach the netzero emission and sustainability target visualized in Flight path 2050. LÄS MER
