  1. 6. Actuators for autonomous microrobots

    Författare :Niklas Snis; Stefan Johansson; Urban Simu; Alvo Aabloo; Uppsala universitet; []
    Nyckelord :Engineering physics; Locomotion; Microrobot; PZT; P VDF-TrFE ; Autonomous; Multilayer; Actuator; Teknisk fysik;

    Sammanfattning : This thesis presents actuators used in autonomous microsystems. Characteristic for all actuators presented is the low drive voltage and the low power consumption. Different motion mechanisms have been studied and applied in various locomotion modules for microrobots. LÄS MER

  3. 7. Some aspects on strength properties in paper composed of different pulps

    Författare :Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Øyvind Gregersen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; reinforcement; multilayer; stratified; handsheet former; abaca; southern pine; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : For papermakers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are desirable both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging and light-weight building material. LÄS MER

  4. 8. Soft X-ray Multilayer Mirrors
