  1. 1. Computational Analysis of Spray Deflector Designs

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

    Författare :Osman Gyokhan Ali; [2023]
    Nyckelord :Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

    Sammanfattning : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. LÄS MER

  3. 2. Neural Networks for Credit Risk and xVA in a Front Office Pricing Environment

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Isabelle Frodé; Viktor Sambergs; [2022]
    Nyckelord :xVA; CVA; OTC; Counterparty Credit Risk; Interest Rate Swaps; Hull-White Model; Machine Learning; Artificial Neural Networks; Gated Recurrent Units; Mathematics and Statistics;

    Sammanfattning : We present a data-driven proof of concept model capable of reproducing expected counterparty credit exposures from market and trade data. The model has its greatest advantages in quick single-contract exposure evaluations that could be used in front office xVA solutions. The data was generated using short rates from the Hull-White One-Factor model. LÄS MER

  4. 3. 3D Representation of EyeTracking Data : An Implementation in Automotive Perceived Quality Analysis

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

    Författare :Tianyou Li; [2021]
    Nyckelord :Eye Tracking; Perceived Quality; Human Car Interaction; Fixation Identification; Data Visualization; Prototyping; Virtual Reality; Aesthetic Design; Geometric Modelling.;

    Sammanfattning : The importance of perceived quality within the automotive industry has been rapidly increasing these years. Since judgmentsconcerning perceived quality is a highly subjective process, eye-tracking technology is one of the best approaches to extractcustomers’ subconscious visual activity during interaction with the product.

  5. 4. Environmental Assessment of Kayak using MFA & LCA : A case study at Melker of Sweden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abhishek Srivastav; Spyridon Xenos; [2020]
    Nyckelord :Kayak; Fiberglass; Flax Fiber; Leisure Purpose; Material Flow Analysis; MFA; Life Cycle Assessment; LCA; Resource-efficiency; Environmental Performance; Sustainable Recreational Activity; Kajak; Glasfiber; Linfiber; Fritidsändamål; Materialflödesanalys; MFA; Livscykelanalys; LCA; Resurseffektivitet; Miljöprestanda; Hållbar fritidsaktivitet;

    Sammanfattning : Kayaking is a watersport activity that involves paddling performed within leisure purposes. Although kayaking provides pleasure to the practitioners, there are some adverse environmental issues concerning the site used to perform kayaking due to the equipment. LÄS MER

  7. 5. Dokumentation av båtar

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Fredrik Leijonhufvud; [2019-05-23]
    Nyckelord :Documentation; Maritime Heritage; Photogrammetry; Craft Science; Forensic Perspective;

    Sammanfattning : The subject of this thesis is documentation of boats. Traditional boats and boat building skills are valuable assets of the cultural heritage and there is an urgent need of documentation and safeguarding. The aim of the study is to test and develop methods for the documentation of boats. LÄS MER
