  2. 1. Modeling and Control of Flexible Manipulators

    Author : Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

    Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. READ MORE

  4. 2. Enhancing Differential Evolution Algorithm for Solving Continuous Optimization Problems

    Author : Miguel Leon; Ning Xiong; Yigen Zenlander; Peter Funk; Ronnie Johansson; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Differential Evolution (DE) has become one of the most important metaheuristics during the recent years, obtaining attractive results in solving many engineering optimization problems. However, the performance of DE is not always strong when seeking optimal solutions. It has two major problems in real world applications. READ MORE

  5. 3. A multi-objective evolutionary approach to simulation-based optimisation of real-world problems

    Author : Anna Syberfeldt; Philip Moore; Robert I. John; Amos Ng; Högskolan i Skövde; []
    Keywords : Evolutionary algorithms; simulation-based optimisation; multi-objective optimisation; noise; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Abstract : This thesis presents a novel evolutionary optimisation algorithm that can improve the quality of solutions in simulation-based optimisation.Simulation-based optimisation is the process of finding optimal parameter settings without explicitly examining each possible configuration of settings.

  6. 4. Application of the Boundary Element Method to combustion noise and half-space problems

    Author : Haike Brick; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impedance plane; Green s function; horn effect; Kirchhoff s surface; Hybrid approach; tyre-road interface;

    Abstract : The Boundary-Element-Method (BEM) is a powerful and established tool in computational acoustics. This thesis aims at an enhancement of the method towards combustion noise and half-space problems.First, it is directly coupled to an incompressible Large Eddy Simulation (LES) to calculate the sound radiation of open flames.

  7. 5. Adaptive Finite Element Methods for Fluid Structure Interaction Problems with Applications to Human Phonation

    Author : Niyazi Cem Degirmenci; Johan Hoffman; Johan Jansson; David Nordsletten; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluid Structure Interaction; Finite Element Method; Contact Modeling; Acoustic Coupling; High Performance Computing; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : This work presents a unified framework for numerical solution of Fluid Structure Interaction (FSI) and acoustics problems with focus on human phonation. The Finite Element Method is employed for numerical investigation of partial differential equations that model conservation of momentum and mass. READ MORE
