  1. 1. Using Social Media and Personality Predictions to Anticipate Startup Success

    University essay from Lunds universitet/Matematisk statistik

    Author : Daniel Stenson; [2023]
    Keywords : Machine Learning; Startup Success Predictions; Founder Personalities; Natural Language Processing; Social Media Analysis; Big 5 Personality Framework; Feed-forward Neural Network; XGBoost.; Mathematics and Statistics;

    Abstract : This thesis explores the potential of integrating predicted founder personalities, based on the Big 5 Personality Framework, into Machine Learning (ML) models to enhance the accuracy of early-stage startup success predictions. Leveraging Natural Language Processing (NLP) techniques, we extracted personality insights from founders' tweets, focusing on US startups funded between 2013 and 2015. READ MORE

  3. 2. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    University essay from KTH/Matematik (Avd.)

    Author : Sigurlaug Rún Jónsdóttir; [2022]
    Keywords : Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Abstract : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. READ MORE

  4. 3. Modelling and Trajectory Planning for a Small-Scale Surface Ship

    University essay from Linköpings universitet/Reglerteknik

    Author : Gustav Zetterqvist; Fabian Steen; [2021]
    Keywords : Marine vessel; Ship; Modelling; Model estimation; Trajectory planning; Optimal control;

    Abstract : Autonomous ships are one way to increase safety at sea and to decrease environmental impact of marine traveling and shipping. For this application, a good representation of the environment and a physical model of the ship are vital components. READ MORE

  5. 4. Development of a 2D Optimal Path Simulation for Ship-to-Shore Cranes : Safe Trajectories within Interchangeable Obstalce Environments

    University essay from Linköpings universitet/Fordonssystem

    Author : Rickard Green; [2020]
    Keywords : Optimal Path; Control; Control theory; Obstacle; Safe trajectories; LiU; ISY; Reglerteknik;

    Abstract : The most advanced ports as of writing of this report are at least somewhat autonomous. Whether discussing the transporters between crane and stack (temporary storage) or cranes, the ports are shifting into a completely autonomous system. This ultimate goal presents a challenge in regards to unloading and loading cargo ships in the harbour. READ MORE

  6. 5. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Sohail Anwar; [2020]
    Keywords : Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Abstract : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). READ MORE
