  1. 26. Steering Method for Nonholonomic Motion Planning based on Quadratic Programming and Differential Flatness

    University essay from KTH/Optimeringslära och systemteori

    Author : Marcus Norgren; [2021]
    Keywords : ;

    Abstract : In this thesis, an optimization based steering methods based on differential flatness and quadratic programming has been investigated. The method has been implemented into an RRT*-planner and tested in simulation. READ MORE

  3. 27. Active Control of High­-Speed Flexible Rotors on Controllable Tilting­-Pad Journal Bearings : Theory and Experiment

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Paul-Henrik Bull; [2021]
    Keywords : ATPJB; Fluid-Film Lubrication; Model based control; Vibration Control;

    Abstract : A common choice of bearing for industrial applications such as turbomachinery and rotating compressors is the Tilting-Pad Journal Bearing (TPJB) due to its excellent stability properties. TPJB's are however limited by the reduction of damping in the fluid film at high velocities. READ MORE

  4. 28. Data-Driven Learning for Approximating Dynamical Systems Using Deep Neural Networks

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Axel Dernsjö; Max Berg Wahlström; [2021]
    Keywords : ;

    Abstract : In this thesis, a one-step approximation method has been used to produce approximations of two dynamical systems. The two systems considered are a pendulum and a damped dual-mass-spring system. READ MORE

  5. 29. Warehouse Optimization by Multi-Agent Rollout Algorithms

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

    Author : Laura Briffa; William Emanuelsson; [2021]
    Keywords : multi-agent problems; reinforcement learning; optimization and optimal control; collision avoidance; warehouse;

    Abstract : Systems consisting of multiple robots are traditionallydifficult to optimize. This project considers such a systemin a simulated warehouse setting, where the robots are todeliver boxes while avoiding collisions. Adding such collisionconstraints complicates the problem. READ MORE

  6. 30. Ramification of polynomials

    University essay from Linnéuniversitetet/Institutionen för matematik (MA)

    Author : Ana Strikic; [2021]
    Keywords : non-pleasantly ramified polynomials; minimally ramified polynomial; lower ramification numbers; minimal ramification; discrete dynamical systems; iterating polynomials; ultrametric fields;

    Abstract : In this research,we study iterations of non-pleasantly ramified polynomials over fields of positive characteristic and subsequently, their lower ramification numbers. Of particular interest for this thesis are polynomials for which both the multiplicity and  the degree of its iterates grow exponentially. READ MORE
