  1. 36. A Hierarchical POD Reduction Method of Finite Element Models with Application to Simulated Mechanical Systems

    University essay from Institutionen för fysik

    Author : Martin Björklund; [2012]
    Keywords : Model reduction; FEM; POD; enrichment; hierarchy; global and local behaviour; Modellreduktion; FEM; POD; berikning; hirarki; globalt och lokalt be- teende;

    Abstract : When simulating mechanical systems the flexibility of the components often has to be taken into account. This is particularly important for simulations when high detailed information is demanded, e.g. to calculate stresses. READ MORE

  3. 37. Ice condensation as a planet formation mechanism

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Katrin Ros; [2012]
    Keywords : Physics and Astronomy;

    Abstract : In models of dust growth in protoplanetary discs focus is typically on coagulation, a mechanism which unfortunately seems incapable of forming particles larger than centimeters. The main reasons for this are that collisions between larger particles lead to bouncing or fragmentation rather than sticking, and that particles approaching meter-sizes drift radially inwards in the disc due to interaction with the surrounding gas.

  4. 38. Mathematical modeling of flocking behavior.

    University essay from KTH/Optimeringslära och systemteori

    Author : Oscar Blomqvist; Sebastian Bremberg; Richard Zauer; [2012]
    Keywords : ;

    Abstract : In this thesis, the ocking behaviour of prey when threatened by a group of predators, is investigated using dynamical systems. By implementing the unicycle model, a simulation is created using Simulink and Matlab. A set of forces are set up to describe the state of the prey, that in turn determines their behaviour in dierent scenarios. READ MORE

  5. 39. Flexible Beams in Dymola

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Teknisk matematik (CI)

    Author : Caroline Malmberg; [2010]
    Keywords : Technology and Engineering;

    Abstract : Mechanical systems can be modeled by connecting rigid bodies with loads and other components. Prescribed motions and initial values can be defined in a system. The behaviour of the rigid bodies can then be studied and their motions can be computed. READ MORE

  6. 40. Dynamical Analysis and System Identification of the Gantry-Tau Parallel Manipulator

    University essay from Institutionen för systemteknik

    Author : Johan Gunnar; [2005]
    Keywords : robotics; identification; nonlinear; parallel; Tau;

    Abstract : This report presents work done in the field of linear and nonlinear system identification on robots. The subject of study has been a new parallel manipulator called Gantry-Tau. The work shall be seen as one of the first steps in the dynamical analysis of the robot. READ MORE
