  1. 1. Improved performance characteristics of induction machines with non-skewed symmetrical rotor slots

    Author : Rathna Chitroju; Chandur Sadarangani; Kelvin C Maliti; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; skewing; cross current losses; radial magnetic forces; magnetic noise; asymmetrical rotor slots; eccentricity; stator vibration; two-dimensional fast fourier transform; finite element method; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. READ MORE

  2. 2. On the Modelling of Train Induced Ground Vibrations with Analytical Methods

    Author : Anders Karlström; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; train; wave propagation; dynamic flexibility; trench; railway track; vibration isolation; wave barrier; soil-structure interaction;

    Abstract : A novel analytical approach to model train induced ground vibrations is proposed. Integral transform solutions are combined with series solutions to obtain fast numericalalgorithms, where a particular designed boundary condition for finite regions is seen to enable the solution procedure.
