Nonlinear Time Series Analysis.
TL;DR: This thesis applies neural network feature selection techniques to multivariate time series data to improve prediction of a target time series and results indicate that the Stochastics and RSI indicators result in better prediction results than the moving averages.

On the potential of uncertainty analysis for prediction of brake squeal propensity
TL;DR: In this paper, an analytical viscously damped self-excited 4-dof friction oscillator with cubic contact force nonlinearity is compared with the instability prediction using the linear complex eigenvalue analysis (CEA) and a nonlinear instability analysis.

Noise performance improvements and tribological consequences of a pad-on-disc system through groove-textured disc surface
TL;DR: In this article, a pad-on-disc system with two kinds of groove configurations is tested and the experimental results show that cutting 45° grooves on the disc surface can significantly reduce the friction noise.

Nonlinear dynamics and synchronization of coupled electromechanical systems with multiple functions
TL;DR: In this paper, the authors deal with the nonlinear dynamics and synchronization of coupled electromechanical systems with multiple functions, described by an electrical Duffing oscillator magnetically coupled to linear mechanical oscillators.
Chaotic dynamics of simple vibrational systems
TL;DR: In this article, a rotator-oscillator type with a finite power source was considered and the authors developed a technique for analysis of the dynamical regimes of complex mechanical systems consisting of a rotor motor coupled to a system with multi-degrees of freedom.

Modelling of automotive disc brake squeal and its reduction using rotor design modifications
TL;DR: In this paper, the authors proposed a numerical approach to reduce disc brake squeal through rotor design modifications using the finite element method (FEM), which is validated based on the measured data extracted from experimental modal analysis for individual brake components in free-free boundary condition and brake assembly under applied pressure.
