    Sammanfattning : The estimation problem of stochastic nonlinear parametric models is recognized to be very challenging due to the intractability of the likelihood function. Recently, several methods have been developed to approximate the maximum likelihood estimator and the optimal mean-square error predictor using Monte Carlo methods. LÄS MER

  4. 38. On the Frequency Domain Analysis of Nonlinear Systems

    Författare :Karin Ståhl; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency domain; Nonlinear systems; Oscillations; Volterra series;

    Sammanfattning : In this report we study how the Volterra series description of nonlinear systems can be applied to some different problems.We study oscillations in nonlinear systems. LÄS MER

  5. 39. Multi Quanta Relaxation and Nonclassicality of Nonlinear Oscillators

    Författare :Aurora Voje; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Damping; Nonclassical States; Entanglement; Quantum Duffing Oscillator;

    Sammanfattning : The focus of the study is the free quantum evolution of Duffing oscillators which are nonlinearly coupled to bosonic environments. The work evolves from a particular system of an undamped, nonlinear graphene resonator mode to a more generalized framework of oscillator modes interacting with two different configurations of bosonic environments.
