  1. 1. Grafisk återgivning av radardetektion av flygplan : Utveckling av ett grafiskt användargränssnitt för PCL- och ADS-B-system

    Kandidat-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Alice Jansson; [2024]
    Nyckelord :GUI; Graphical user interface; PCL; Passive Coherent Location; ADS-B; HCI; Human-computer Interaction; Electronic warfare; Grafiskt användargränssnitt; MMI; Människa-maskin-interaktion; PCL; Passiv radar; ADS-B; Ljudkrig;

    Sammanfattning : Passive Coherent Location (PCL), eller Passiv Radar som det populärt kallas, är enteknologi inom radarlära som innefattar radartyper som inte själva skickar ut elektromagnetiska vågor för att finna och undersöka ett mål. Istället använder sig dessa radartyper av befintliga signaler, såsom radio- och TV-sändningar för att detektera mål. LÄS MER

  3. 2. Using GPU-aware message passing to accelerate high-fidelity fluid simulations

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

    Författare :Jacob Wahlgren; [2022]
    Nyckelord :high-performance computing; computational fluid dynamics; spectral element method; graphical processing units; message passing interface; högprestandaberäkningar; beräkningsströmningsdynamik; spektralelementmetoden; grafikprocessorer; meddelandeförmedlingsgränssnitt;

    Sammanfattning : Motivated by the end of Moore’s law, graphics processing units (GPUs) are replacing general-purpose processors as the main source of computational power in emerging supercomputing architectures. A challenge in systems with GPU accelerators is the cost of transferring data between the host memory and the GPU device memory. LÄS MER

  4. 3. Kalman filters as an enhancement to object tracking using YOLOv7

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Axel Jernbäcker; [2022]
    Nyckelord :statistics; applied mathematics; machine learning; kalman filter; statistik; tillämpad matematik; maskinlärning; kalman filter;

    Sammanfattning : In this paper we study continuous tracking of airplanes using object detection models, namely YOLOv7, combined with a Kalman filter. The tracking should be able to be done in real-time. The idea of combining Kalman filters with an object detection model comes from the lack of time-dependent context in models such as YOLOv7.

  5. 4. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Daniel Nesic; [2022]
    Nyckelord :Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Sammanfattning : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. LÄS MER

  7. 5. Quotation for Customer Proposal and Performance Analysis for aircraft maintenance

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Antoine Bezier; [2022]
    Nyckelord :Maintenance; aircraft; quotation; performance analysis; internship; aerospace engineering; databases; feedback; customer support; request for proposal; repair; technical work preparation.; Flygplansunderhåll; prestandaanalys; flygteknik; databaser; kommersiellt erbjudande; kontinuerlig förbättring.;

    Sammanfattning : By working as an intern with the Quotation Officer of Sabena Technics Nîmes facility,an aircraft maintenance company, this degree project highlights the different factors totake into account in a quotation of civil planes (B737/B767/A320/A330) by analysingwork packages from airline company, applying a process to estimate the importantdata as the man hours or tools, and using my technical knowledge to understandmaintenance tasks. Management knowledge for commercial sale reviews was usefulas well, this job is in the middle of the commercial team and and the technicalteam. LÄS MER
