  1. 21. Quality assessment of mineral wool insulation plates : Using ultrasonic non-destructive testing

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Linus Ikonen; Daniel Nilsson; [2019]
    Nyckelord :Non-destructive testing; linear ultrasound; mineral wool; fibrous materials; acoustics; frequency response; signal attenuation; Oförstörande provning; linjärt ultraljud; stenull; fibrösa material; akustik; frekvenssvar; signalförsvagning;

    Sammanfattning : In the manufacturing process of mineral wool insulation plates, defects arise, such as unmelted base minerals and uncured binder which gets embedded within the plates. To be able to sort out these defective plates from a manufacturing line, a reliable quality assessment is needed. LÄS MER

  3. 22. Robot Vacuum cleaner

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Sammanfattning : Although a robot vacuum cleaner is a well-known product, development is still interesting. Better working sensors and more sophisticated algorithms and sensors are used in new cleaners. LÄS MER

  4. 23. Evaluating LoRaWAN for IoT applications by developing a wireless parking space monitoring sensor

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

    Författare :Felix Jontegen; Emma Good; [2018]
    Nyckelord :LoRaWAN; IoT; Parking space monitoring; Car detection; The Things Network; LoRaWAN; IoT; Parkeringsplatsbevakare; Bildetektering; The Things Network;

    Sammanfattning : The process of finding a parking space can be a tedious task that drivers spent too much time on today. With the rising threat from global warming, reducing the time spent driving is vital. LÄS MER

  5. 24. Phased Array Ultrasonic Testing of Austenitic Stainless Steel Welds of the 11 T HL-LHC Dipole Magnets

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Marcus Lorentzon; [2018]
    Nyckelord :Phased Array Ultrasonic Testing; PAUT; Non-Destructive Testing; Austenitic Stainless Steel; Welds; CERN;

    Sammanfattning : A routine non-destructive test method based on Phased Array Ultrasonic Testing (PAUT) has been developed and applied for the inspection of the first 11 T dipole prototype magnet half shell welds, and the test results are compared with the radiography and visual inspection results of the same welds. A manual scanner and alignment system have been developed and built to facilitate the inspection of the 5. LÄS MER

  7. 25. Front loader task automation with distance measurement

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Emil Risberg; [2018]
    Nyckelord :;

    Sammanfattning : Front loaders are used in many agricultural applications. They are used in daily tasks that are performed by operators. The operator uses multiple different front loader equipment carrying out tasks, which are more or less repetitive. A common thing between these tasks even though different equipment is used, is that the working cycle is similar. LÄS MER
