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.

Analysis of disc brake noise using a two-degree-of-freedom model
TL;DR: In this article, a two-degree-of-freedom model is adopted where the disc and the pad are modelled as single modes connected by a sliding friction interface, and the interaction between the pad and the disc is investigated.

Transient non-linear dynamic analysis of automotive disc brake squeal – On the need to consider both stability and non-linear analysis
TL;DR: In this paper, the authors investigated the contribution of fundamental frequencies and harmonic components in non-linear transient and stationary dynamics for disc brake system subjected to single and multi-instabilities and showed that an under-estimation of the unstable modes observed in the nonlinear time simulation can be calculated by the stability analysis.

Chaos in brake squeal noise
TL;DR: In this paper, the authors analyzed the brake squeal data obtained from a full brake system on a noise dynamometer with nonlinear analysis techniques and showed that lower dimensional attractors are isolated and quantified by dynamic invariants such as correlation dimension estimates or Lyapunov exponents.

Statistical analysis of brake squeal noise
TL;DR: In this article, the correlation analysis between the time-averaged friction coefficient and peak sound pressure data is performed by applying a semblance analysis and a joint recurrence quantification analysis.
