  1. 21. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Linnéa Tebelius; [2022]
    Keywords : Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Abstract : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.

  3. 22. Inverse Atmospheric Dispersion Modeling in Complex Geometries

    University essay from Umeå universitet/Institutionen för fysik

    Author : Charlie Pelland; [2022]
    Keywords : atmospheric dispersion modeling; dispersion modeling; invers dispersion modeling; atmospheric dispersion; invers atmospheric dispersion; CFD; computational fluid dynamics; radioactive release; openfoam; CRBN; dry deposition; dry deposition velocity; scavenging effect; wet deposition; optimization model; Reynolds Averaged Navier-Stokes; adjoint mode; time-dependent rain simulation; time-dependent rain; time dependent rain simulation; time dependent rain;

    Abstract : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. READ MORE

  4. 23. Empirical Data Based Predictive Warning System on an Automated Guided Vehicle

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Anton Blåberg; Gustav Lindahl; [2022]
    Keywords : AGV; Automated Guided Vehicles; Autonomous Mobile Robots; LiDAR; Warning Field; Warning System; Collision Avoidance; Braking System; Robotics; Autonomous Vehicles; Path Predictive; Position Forecasting; Speed Regulation; Decision Making; Protective Field; Protective System; Industry 4.0; AI; Självkörande truckar; Varningsfält; Varningssystem; Säkerhetsfält; Säkerhetssystem; Industri 4.0; Automatiskt inbromsning; Positionsprognos; Beslutsfattande;

    Abstract : An Automated Guided Vehicle (AGV) must follow protective regulations to avoidcrashing into people when autonomously driving in industries. These safety norms require AGVs to enable protective fields, which perform hard braking when objects enter aspecific area in front of the vehicle. READ MORE

  5. 24. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  6. 25. The Dynamics of Neural Networks Expressivity with Applications to Remote Sensing Data

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

    Author : Hui Zhang; [2022]
    Keywords : Neural Networks; Linear Regions; Expressivity; Initialization; Remote Sensing; Neurala nätverk; linjära regioner; uttrycksfullhet; initialisering; fjärranalys;

    Abstract : Deep neural networks (DNN) have been widely demonstrated to be more powerful than their shallower counterparts in a variety of computer vision tasks and remote sensing applications. However, as many techniques are based on trial-and-error experiments as opposed to systematic evaluation, scientific evidence for the superiority of DNN needs more theoretical and experimental foundations.
