  1. 1. Structural and Antibacterial Properties of Silver(I) Compounds with N-donor Ligands: A Challenge for Medical Applications

    Författare :Al-Shimaà A A Massoud; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; silver I compounds; solution chemistry; antibacterial activity;

    Sammanfattning : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. LÄS MER

  3. 2. Instability in Settling Fibres : A Numerical Study

    Författare :Feng Zhang; Anders A. Dahlkild; Fredrik Lundell; Mark Martinez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bre suspensions; sedimentation; instability; mixture model; point-particle mode;

    Sammanfattning : Sedimenting suspensions exist in a varity of natural phenomena and industrial applications. It is already observed in experiments that the dilute fibre suspensions experience a concentration instability under gravity at low Reynolds numbers. Initially well-mixed suspensions become inhomogeneous and anisotropic due to this instability. LÄS MER

  4. 3. 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
