  1. 6. Nonlinear Methods of Aerodynamic Data-driven Reduced Order Modeling

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Arvid Forsberg; [2022]
    Keywords : machine learning; aerodynamics; autoencoder; kernel transformation; principal component analysis; nonlinear; regression; modeling; surrogate model; reduced order modeling; neural network;

    Abstract : Being able to accurately approximate outputs of computationally expensive simulations for arbitrary input parameters, also called missing points estimation, is central in many different areas of research and development with applications ranging from uncertainty propagation to control system design to name a few. This project investigates the potential of kernel transformations and nonlinear autoencoders as methods of improving the accuracy of the proper orthogonal decomposition method combined with regression.

  3. 7. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ashley Hall; [2022]
    Keywords : water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Abstract : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. READ MORE

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

    University essay from KTH/Matematik (Avd.)

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

    Abstract : 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. 9. Investigation of the wing design and endurance of an ultralight electrical aircraft

    University essay from Lunds universitet/Innovation

    Author : Vanda Ericson; Jonathan Palmgren; [2022]
    Keywords : Aerodynamics; Electrical Aviation; CFD; Endurance; Drag; Technology and Engineering;

    Abstract : The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). READ MORE

  6. 10. The Impact of Social Media Marketing on Customer Loyalty

    University essay from Linnéuniversitetet/Institutionen för marknadsföring (MF)

    Author : Matthew Rhodes; Julian Maracic; Tobias Axberg; [2022]
    Keywords : Customer Loyalty; Social Media Marketing Activities; SMMA; Entertainment; Interaction; Trendiness; Customization.;

    Abstract : Background: To date, there have been several studies conducted on how social media marketing affects customer loyalty. However, they have been narrowed down to specific areas, such as luxury fashion, the airplane industry, and so on. Therefore, there is a literature gap on how social media marketing affects customer loyalty in general. READ MORE
