  1. 16. Theory and use of chaotic oscillators in electronic communication systems

    Författare :Anders J Johansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chaos; complexity theory; random numbers; Chaotic oscillators;

    Sammanfattning : The theory and applications of chaotic oscillators in electronic commuication are investigated. A method of random number generation utilising a chaotic double scroll oscillator is proposed and evaluated. The theoretical limits of the randomness of the method is analysed.. LÄS MER

  3. 17. Some Aspects of Wear and Structural Dynamics

    Författare :Jakob Knudsen; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Mechanical engineering; hydraulics; chaos; interfacial breakdown; stability; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vacuum technology; fretting wear; fretting map; vibro-impact dynamics;

    Sammanfattning : The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. LÄS MER

  4. 18. Ecologies of Practices and Thinking

    Författare :Elke Marhöfer; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; new materialism; film; image; matter; nonhuman; more-than-human; other-than-human; not-so-human; ecology; agriculture; otherness; storytelling; enunciation; post-context; post-history; animism; colonialism; becoming with; seeing together; lines of flight; modes; animals; plants; things; territories; multiplicities; chaos; expressive continuum; rerational aesthetics; radical empiricism; Baruch Spinoza; Gilles Deleuze; Félix Guattari; Isabelle Stengers; Donna Haraway; Anna Lowenhaupt Tsing; Brian Massumi; Danièle Huillet; Jean Marie Straub;

    Sammanfattning : How does a new materialist film practice look? To approach this question the practice-led material driven research explores dynamic ecological relations and processes of thinking and practicing. It employs an animist methodology which allows it to relate to the nonhuman as an active participant, rather than a passive object of inquiry. LÄS MER

  7. 20. Electromechanical Phenomena in Superconducting and Normal Nanostructures

    Författare :Milton Eduardo Peña-Aza; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoelectromechanical systems; nanoelectromechanical Josephson junctions; metallic carbon nanotubes; ground-state cooling; chaos;

    Sammanfattning : This thesis summarizes a series of theoretical studies on the electromechanical properties of nanostructures made of superconducting and/or metallic elements. The first part of the work is devoted to the analysis of the interactions between the electronic and mechanical degrees of freedom in suspended nanowires. LÄS MER
