  1. 1. A case study of disjunctive programming: Determining optimal motion trajectories for a vehicle by mixed-integer optimization

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oskar Jagstedt; Elias Vitell; [2023]
    Keywords : Optimization; disjunctive programming; integer programming; Gurobi; big-M; nonlinear programming;

    Abstract : This report considers an application of mixed-integer disjunctive programming (MIDP)where a theoretical robot can jump from one point to another and where the number ofjumps is to be minimized. The robot is only able to jump to the north, south, east andwest. READ MORE

  3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  4. 3. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

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

    Author : Somnath Balaji Suresh Kumar; [2023]
    Keywords : Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

    Abstract : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

  5. 4. And Action! : A Study of the Semantic Domains of Action through Interpretation of Metaphor

    University essay from

    Author : Henrik Westerdahl; [2023]
    Keywords : Semantic domain; Semantic dimension; Semantic pattern; Metaphor; Body in metaphor;

    Abstract : The aim of this essay is determining and describing some of the semantic domains of the concept of action. Action belongs to the type of abstract nouns with unclear semantic domains. In other words, there are difficulties in determining the precise semantic patterns that the word ‘action’ refers to. READ MORE

  6. 5. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Amal Vinod; [2023]
    Keywords : Volumetric rendering; rendering; Comet; Coma; Dust Coma; Gas Coma; Blender; Comet Interceptor;

    Abstract : The Comet Interceptor is a joint mission by European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) which seeks to perform a flyby over a Long Period Comet using a multi-element spacecraft. The Comet Interceptor comprises three spacecrafts- A, B1 and B2. READ MORE
