  1. 1. Probabilistic Added Wave Resistance Predictions for Design of RoPax Ferries

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonathan Viinikka; [2023]
    Keywords : Added wave resistance in head waves; Roll-on Roll-off Passenger ferry; Probabilistic wave environment; Semi-empirical method; Adderat vågmotstånd i motsjö; Roll-on Roll-off Passagerar Fartyg; Probabilistiska vågförhållanden; Semiempiriska beräkningsmethoder;

    Abstract : This thesis investigates reasons for significant uncertainties in added wave resistance predictionsand how wave conditions can potentially affect the design of RoPax ferries. The objectiveis to find a suitable prediction method of added wave resistance for the RoPax ferry designapplication. READ MORE

  3. 2. Ocean rogue wave analysis for the development of safer navigation systems. : A Thesis submitted to the University of Gävle for the degree of Bachelor of Mathematics

    University essay from Högskolan i Gävle/Matematik

    Author : Sergio Manzetti; [2023]
    Keywords : ;

    Abstract : Rogue waves are unexpectedly high waves of 2.5X the significant wave height and which occur in nearly all phases of nature, from  oceans, to fiber-optic cables and atmospheric air-masses. In the ocean, rogue waves pose a significant danger to shipping and fishing vessels and have been found to reach 27. READ MORE

  4. 3. High tide flooding in near future projections for popular travel destinations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : David Ebert; [2023]
    Keywords : Physical Geography and Ecosystem analysis; High tide flooding; Projections; Adaptation and mitigation strategies; Lunar precession; Nodal cycle; Cycle of lunar perigee; Earth and Environmental Sciences;

    Abstract : High tide flooding (HTF) is becoming more common in coastal regions of the United States, although this phenomenon remains largely undocumented in published literature from other parts of the world. No matter the emissions scenario over the next decades, sea level rise (SLR) is projected to continue worldwide until at least the end of the 21st century, continually pushing the frequency and severity of HTF.

  5. 4. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yuan Cheng; [2022]
    Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

    Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

  6. 5. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Abstract : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. READ MORE
