71. Interpreting Turbulent Flows through Statistical Learning Methods

Vanesa Guerrero (Universidad Carlos III de Madrid)

Data science

Two data-driven approaches for interpreting turbulent-flow states are discussed. On the one hand, multidimensional scaling and K-medoids clustering are applied to subdivide a flow domain in smaller regions and learn from the data the dynamics of the transition process. The proposed method is applied to a direct numerical simulation dataset of an incompressible boundary layer flow developing on...

118. Functional Data Analysis in Reliability and Maintenance Engineering: An Application to Aircraft Engines

Reliability

In this work, a practical reliability analysis and engine health prognostic study is performed using a Functional Data Analysis (FDA) approach. Multi-sensor data collected from aircraft engines are processed in order to solve one of the most important reliability analysis problems, which is estimating the health condition and the Remaining Useful Life (RUL) of an aircraft engine. Time-variant...

159. A Variance-Based Importance Index for Systems with Dependent Components

Dr Alfonso Suarez-Llorens (Universidad de Cádiz)

Reliability

Our work proposes a variance-based measure of importance for coherent systems with dependent and heterogeneous components. The particular cases of independent components and homogeneous components are also considered. We model the dependence structure among the components by the concept of copula. The proposed measure allows us to provide the best estimation of the system lifetime, in terms of...
