  1. 11. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Tetsuro Goda; [2017]
    Keywords : Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Abstract : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. READ MORE

  3. 12. Optimization of Extreme Environment Cyclic Testing : Analysis of thermal cycle load cases on a plastic cab component through simulation and testing

    University essay from KTH/Fordonsdynamik

    Author : John Sedin; [2016]
    Keywords : ;

    Abstract : The purpose of this Master thesis was to deepen the knowledge and understanding regarding control parameters for the Extreme Environment Cyclic Testing (EECT) on interior and exterior cab components. The investigated parameters were temperature gradient, length of the warm and cold sections and number of cycles. READ MORE

  4. 13. Micromechanical study of PFZ in aluminum alloys

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Hossein Shariati; [2016]
    Keywords : precipitate-free zones; strain gradient plasticity; mikromekanik;

    Abstract : There are a number of experiments showing that the ductility of aluminum alloys decreases during age-hardening heat treatment. Observing the grains of age-hardened aluminum alloys at the micron scale, one can notice that there are precipitate-free zones (PFZs) along the grain boundaries. READ MORE

  5. 14. Effect of texture and blasting pressure on residual stress and surface modifications in wet sand blasted α-Al2O3 coating

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Erik Ekström; [2015]
    Keywords : XRD; residual stress; alumina; Al2O3; blasting; annealing; activation energy;

    Abstract : Recently, wet sand blasting on coated cutting tool inserts has drawn interest to the tooling industry due to its positive effects on cutting performance and tool life. This performance boost has partly been attributed to the buildup of compressive residual stresses in the coating during the blasting process. READ MORE

  6. 15. MIMO Channel Equalization and Symbol Detection using Multilayer Neural Network

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Athar Waseem; A.H.M Sadath Hossain; [2013]
    Keywords : MIMO; ISI; NN; SER; Channel Equalizer; QAM;

    Abstract : In recent years Multiple Input Multiple Output (MIMO) systems have been employed in wireless communication systems to reach the goals of high data rate. A MIMO use multiple antennas at both transmitting and receiving ends. These antennas communicate with each other on the same frequency band and help in linearly increasing the channel capacity.
