  1. 21. Advancing Modeling and Tracking of Deformable Linear Objects for Real-World Applications

    Författare :Yuxuan Yang; Todor Stoyanov; Johannes A Stork; Ville Kyrki; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deformable Linear Object; Model Learning; Model-based Control; Tracking; Robustness;

    Sammanfattning : Deformable linear objects (DLOs), such as cables, wires, ropes, and sutures, are important components in various applications in robotics. Although automating DLO manipulation tasks through robot deployment can offer benefits in terms of cost reduction and increased efficiency, it presents difficult challenges. LÄS MER

  3. 22. Linear Time-Varying Systems: Modeling and Reduction

    Författare :Henrik Sandberg; Anders Rantzer; Alexandre Megretski; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear time-varying; model reduction; balanced truncation; error bounds; power converters; harmonics; periodic modeling; inverter locomotive; linear time-varying; model reduction; balanced truncation; error bounds; power converters; periodic modeling; harmonics; inverter locomotive;

    Sammanfattning : Linear time-invariant models are widely used in the control community. They often serve as approximations of nonlinear systems. For control purposes linear approximations are often good enough since feedback control systems are inherently robust to model errors. In this thesis some of the possibilities for linear time-varying modeling are studied. LÄS MER

  4. 23. Model Order Reduction Based on Semidefinite Programming

    Författare :Aivar Sootla; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model reduction; parameterized model reduction; nu-gap metric; semidefinite programming; frequency response matching.;

    Sammanfattning : The main topic of this PhD thesis is complexity reduction of linear time-invariant models. The complexity in such systems is measured by the number of differential equations forming the dynamical system. This number is called the order of the system. LÄS MER

  5. 24. Polarized light spectroscopy studies of model membranes and DNA

    Författare :Maxim Kogan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; emission; ruthenium dipyridophenazine complex; lipid bilayer; linear dichroism; membrane model; membrane orientation; bimolecular probe; DNA;

    Sammanfattning : Over the past decades Linear Dichroism (LD) spectroscopy has proven to be a powerful tool for studies of structure and functioning of different cell constituents, including DNA, cell membranes and proteins. Due to structural complexity of cell constituents, the LD studies of biomolecules depend on development of simplified model systems, which can mimic the original structure and functionality of the cell components.

  7. 25. Emittance preservation and luminosity tuning in future linear colliders

    Författare :Peder Eliasson; Tord Ekelöf; Grahame Blair; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; linear colliders; CLIC; ILC; emittance preservation; luminosity tuning; beam-based alignment; dispersion free steering; tuning bumps; trajectory feedback; static imperfections; dynamic imperfections; jitter; ground motion; ATL model; multi-pulse emittance; curved tunnel; Elementary particle physics; Elementarpartikelfysik;

    Sammanfattning : The future International Linear Collider (ILC) and Compact Linear Collider (CLIC) are intended for precision measurements of phenomena discovered at the Large Hadron Collider (LHC) and also for the discovery of new physics. In order to offer optimal conditions for such experiments, the new colliders must produce very-high-luminosity collisions at energies in the TeV regime. LÄS MER
