  text: <jats:p>Historical condition monitoring data from technical systems can be
    utilized to develop data-driven models for predicting the remaining useful life
    (RUL) of similar systems, whereas the Health Index (HI) often is a crucial component.
    The development of robust and accurate models requires meaningful features that
    reflect the system’s degradation process, enabling an accurate prediction of the
    system's HI. Traditionally, the identification of those is supported by one of
    various feature ranking methods. In literature, feature interdependencies and
    their transferability across various similar systems are not sufficiently considered
    in feature selection, exacerbating the challenge of HI prediction posed by the
    scarcity of data and system diversity in real-world applications. This work addresses
    this gaps by demonstrating how filter-based feature selection, incorporating failure
    thresholds and cross correlations, enhances feature selection leading to improved
    HI prediction. The proposed methodology is applied to a novel dataset* obtained
    from run-to-failure experiments on geared motors conducted as part of this study,
    which presents the aforementioned challenges. It is revealed that classical feature
    selection, consisting of feature ranking only, leaves potential untapped, which
    is utilized by the proposed selection methodology. It is shown that the proposed
    feature selection methodology leads to the best result with a RMSE of 0.14 in
    predicting the HI of a constructive different gearbox, while the features, determined
    by classical feature selection, lead to a RMSE of 0.19 at best.</jats:p>

  text: This paper investigates the remaining useful lifetime (RUL) estimation of
    bearings under dynamic, i.e., time-varying, operating conditions (OC). Unlike
    conventional studies that assume constant OC in bearing accelerated life tests,
    we introduce a dataset with time-varying OC during run-to-failure experiments,
    simulating real-world scenarios. We explore data-driven approaches to identify
    the transition point from a healthy to an unhealthy state and estimate the RUL.
    Additionally, we examine strategies for integrating OC information to enhance
    RUL estimations. These methodologies are evaluated through numerical experiments
    using various machine learning algorithms.
