  2. 6. On synchronization of heavy truck transmissions

    Author : Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. READ MORE

  4. 7. Conformal Maps, Bergman Spaces, and Random Growth Models

    Author : Alan Sola; Haakan Hedenmalm; Robert Berman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conformal maps; Bergman kernels; planar growth models; MATHEMATICS; MATEMATIK;

    Abstract : This thesis consists of an introduction and five research papers on topics related to conformal mapping, the Loewner equation and its applications, and Bergman-type spaces of holomorphic functions. The first two papers are devoted to the study of integral means of derivatives of conformal mappings. READ MORE

  5. 8. Numerical modeling of pulsed volume discharges for the generation of ozone

    Author : J. Olof Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modeling; ozone production; parameterstudy; pulsed discharge;

    Abstract : The pulsed electric volume discharge is a new alternativefor the efficient generation of ozone in compact systems. Thisthesis presents a parameter study of the reactions in this kindof homogeneous discharge, using a here developed numericalmodel DISCHEM which solves plasma chemical kinetic rate andenergy equations.

  6. 9. Characterisation and Some Statistical Aspects of Univariate and Multivariate Generalised Pareto Distributions

    Author : Nader Tajvidi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; generalised Pareto distribution; multivariate extreme value theory; multivariate Pareto distribution; small sample properties; Bartlett s correction; maximum likelihood; statistical computations; simulation AMS 1991 subject classification: 62F11; 62E20; 60F17; 65U05; 62E20;

    Abstract : Extreme value theory is about the distributions of very large or very small values in a time series or stochastic process. This has numerous applications connected with environmental science, civil engineering, materials science and insurance. READ MORE

  7. 10. Simulating rolling noise on ballasted and slab tracks: vibration, radiation, and pass-by signals

    Author : Jannik Theyssen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway rolling noise; Numerical modelling; Green s functions; Time domain; Spherical harmonics; Slab track; 2.5D FE BE;

    Abstract : Shifting to rail-bound freight and passenger traffic is key in Europe's strategy towards transport decarbonisation. However, increasing railway traffic can increase environmental noise pollution. Rolling noise is often the dominant noise source. It originates from the interaction of the rough running surfaces of wheel and rail. READ MORE
