  2. 1. Flow structures in solid-liquid suspensions in mixing and confined jets

    Author : Matthias Eng; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis is an investigation of the influence of solid particles on different liquid flow systems. Large-scale periodic fluctuations such as macro instabilities (MI) and particle cloud dynamics in a mixing vessel and confined jets were studied experimentally and compared to numerical results from CFD simulations.

  6. 4. On the control of virtual violins : Physical modelling and control of bowed string instruments

    Author : Matthias Demoucron; Anders Askenfelt; Rene Causse; Benoit Fabre; Marcelo Wanderley; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bowed string; physical modelling; sound synthesis; performance control; violin playing; Corde frottée; modélisation physique; synthèse sonore; contrôle gestuel; violon; Struken sträng; fysikalisk modellering; ljudsyntes; musikutförande; violinspel; Other physics; Övrig fysik; Computer science; Datavetenskap; Acoustics; Akustik;

    Abstract :   This thesis treats the control of sound synthesis of bowed string instruments based on physical modelling. The work followed two approaches: (a) a systematic exploration of the influence of control parameters (bow force, bow velocity, and bow-bridge distance) on the output of a physical model of the violin, and (b) measurements and analyses of the bowing parameters in real violin playing in order to model and parameterize basic classes of bowing patterns for synthesis control.

  7. 5. On the influence of surface roughness on rolling contact forces

    Author : Oskar Lundberg; Ines Lopez Arteaga; Leif Kari; Matthias Kröger; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling contact; Surface roughness; Contact forces; Contact modelling; Friction; Road; Asphalt; Substrate; Test-rig; Sliding; Stick–slip; Tyre; Rubber; Tread-block; Wheel–rail interaction; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.
