  1. 26. System för optisk mätning av linjeprofil

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Victor Svahn; Andreas Johansson; [2021]
    Nyckelord :;

    Sammanfattning : Today’s industry is moving towards a fourth revolution based on digitilizing technologies to reduce errors and streamline processes. When manufacturing hydraulicsand other pressurized systems, couplings are pressed onto pipes and hoses that mustbe able to maintain an expected pressure. LÄS MER

  3. 27. 2D-material nanocomposites with nonlinear optical properties for laser protection

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

    Författare :Nils Ross; [2021]
    Nyckelord :optical power limiting; OPL; laser protection; nanocomposites; 2D-materials; graphene oxide; MXene; Ti3C2; melting gel; graphene; two-dimensional materials; nonlinear optical properties; NLO; spectroscopy;

    Sammanfattning : Lasers are increasingly used for a wide range of different applications for both civil and military purposes. Due to the distinct properties of laser light, use of lasers often comes with a risk of damage to the human eye and other optical sensors. Therefore, an effective laser protection is needed. LÄS MER

  4. 28. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Martin Passad; [2021]
    Nyckelord :Physics; Optics; Lasers; Environment; Hydrogen; Hydrogen Energy; Ammonia Energy; DFWM; Ammonia; Nitrous Oxide; Ammonia Flame; Ammonia Combustion; Physics and Astronomy;

    Sammanfattning : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. LÄS MER

  5. 29. Strengthening Efficiency and Safety in Forklift Operations through Autobiographical Design

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

    Författare :Nino Khodr; [2021]
    Nyckelord :Forklifts; Warehouse; Efficiency; E-Commerce; Internet of things.;

    Sammanfattning : Forklift vehicles used for moving pallets and boxes in warehouses, have recently been integrated with Internet of Things (IoT) technology, in effect making forklifts networked and in parts controllable from afar. Human operators now carry out tasks according to instructions displayed on the screen of the IoT-forklift instead of just maneuvering around and executing tasks as they see fit. LÄS MER

  7. 30. Test setup for LDMX HCal readout

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Joshua Greaves; [2020]
    Nyckelord :Dark matter; LDMX; dark photon; hadronic calorimeter; photomultiplier tube; Physics and Astronomy;

    Sammanfattning : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.
