  2. 1. Control Design and Performance Analysis of force Reflective Teleoperators - A Passivity Based Approach

    Author : Henrik Flemmer; KTH; []
    Keywords : Teleoperator; Force Feedback; Passivity; Stiff Contacts; Control; Robustness; Transparency; Bone Milling; Uncertainty;

    Abstract : In this thesis, the problem of controlling a surgical masterand slave system with force reflection is studied. The problemof stiff contacts between the slave and the environment isgiven specific attention. The work has been carried out at KTHbased on an initial cooperation with Karolinska Sjukhuset.

  4. 2. Elastohydrodynamically lubricated finite line contacts operating under transient conditions

    Author : Tobias Hultqvist; Roland Larsson; Lars-Erik Stacke; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The effect of greenhouse gas emissions contributing to the global warming is today becoming an increasingly important problem worldwide and has led to increased efforts being made on improving tribological performance of interacting surfaces in mechanical systems. Due to increasingly stringent CO2regulations, a reduced fuel consumption has become a key area of interest for the automotive industry where low cost, low emission solutions are continuously developed and where low friction alternatives to machine elements currently in use are evaluated.
