  1. 6. Steering control for haptic feedback and active safety functions

    Författare :Tushar Chugh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; position control; coupled stability; passivity; steering system; uncoupled stability; transparency; active safety; haptic feedback; torque control; state estimation;

    Sammanfattning : Steering feedback is an important element that defines driver–vehicle interaction. It strongly affects driving performance and is primarily dependent on the steering actuator's control strategy. LÄS MER

  3. 7. Fågel, fisk eller förundran? : En studie av förhållningssätt i existentiella frågor, baserad på uppsatser skrivna på ett mångkulturellt vuxengymnasium

    Författare :Tove Frisch; Boel Englund; Claes-Göran Wenestam; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Philosophy of life; God; meaning of life; death; contradiction; existentialism; determinism; reason; emotion; intuition; change; activity; passivity; society; culture; identity; religion; language; freedom; facticity; Sartre; Education; Pedagogik;

    Sammanfattning : Fågel, fisk eller förundran? A study of existential attitudes based on essays written in a multicultural upper secondary school for adults The aim of this study is to survey and interpret outlooks on life as expressed in 175 essays written (1999-2001) in a multicultural Swedish suburb by adult students learning Swedish, Swedish as a Foreign Language, and Philosophy. What are the recurring themes in these essays? How do they reflect the fundamental existential problems of their authors? The theoretical background rests on existential hermeneutics with Sartre (1943, 1946, 1984) as the most important philosophical source. LÄS MER

  4. 8. Analysis of dc-network stability of VSC-based HVDC grids

    Författare :Gustavo Pinares; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power dependent admittance; resonance; HVDC; passivity; Multi-terminal HVDC system; VSC; dc-network stability;

    Sammanfattning : This thesis presents a modelling approach for the investigation of dc-network stability in HVDC grids. It consists on dividing the system under analysis into subsystems such that their individual impact on the stability of the overall system can be studied. LÄS MER

  7. 10. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

    Författare :Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
    Nyckelord :Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

    Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER
