An Automatic Data Augment Method for Remaining Useful Life Prediction of Aeroengines

Zequan Wang — 2026-01-15

The prediction of remaining service life in complex aviation engine systems is of great significance for airlines to develop maintenance plans for engines and reduce maintenance cost. However, the complex operating conditions of the engine and insufficient fault mode data limit the prediction accuracy. One direction to solve such problems is data augmentation, which aims to generate synthetic data from real datasets to expand training samples and improve the model's generalization ability. Admittedly, there are already many mature data augmentation methods, but the optimal data augmentation strategy for RUL prediction tasks varies in different situations. Confirming which data augmentation strategy is most suitable for the current remaining useful life prediction problem requires human experience or extensive parameter experiments. This work proposes an automatic data augmentation method(AdaRUL),Build an automatic search space and use reinforcement learning algorithms to search for the optimal strategy in the automatic search space to expand the sample dataset. The experiments conducted on the C-MAPSS public dataset provided by NASA demonstrate that AdaRUL has successfully generated high fidelity multivariate monitoring data. In addition, these generated data effectively support RUL prediction tasks and significantly improve the predictive ability of underlying deep learning models.

Research On the Teaching Integration of Vocal Music and Ancient Poetry Culture in Colleges and Universities Under the Vision of Interdisciplinary Integration

Li Liu — 2026-01-15

Ancient poetry is a treasure of traditional Chinese culture, and ancient Chinese poetry and songs are an important vocal genre created on its basis. By analyzing the development context of ancient poetry and songs and their cultural connotations, this paper explains their importance in current college education, and puts forward specific paths to strengthen cultural self-confidence from the long history, taste the cultural connotation from desk work, and broaden the path of cultural inheritance from multiple presentations. In the context of advocating interdisciplinary integration in the construction of new liberal arts in colleges and universities, this paper puts forward the teaching concept of deep integration of vocal music performance and ancient poetry culture in view of the current phenomenon of emphasizing skills over literature in vocal music teaching in colleges and universities. This study takes the famous work of Song Dynasty poet Yan Shu, "Butterfly Love Flower, Threshold Chrysanthemum Sorrowful Smoke Orchid Weeping Dew" as the core case, and comprehensively uses literature research, case analysis and teaching practice to deeply explore the literary meaning, musical characteristics and integration path of the lyrics in vocal music teaching.

Research On the Problems and Countermeasures of Teacher-Child Interaction in Small Class Health Education Teaching Activities

Yuchen Luo — 2026-01-15

The health field is the first of the five major fields, and health education lays a good foundation for children's health and a better life throughout their lives. Teacher-child interaction is a two-way communication between teachers and children. Correct teacher-student interaction can promote the creation of a democratic and harmonious classroom atmosphere, the interpersonal communication of preschool children, and the sensitivity of teachers in activities. This study mainly uses the observation method to analyze the current situation of teacher-child interaction in small class health teaching activities, and finds that there is a lack of teaching of children's daily health knowledge, the dominance of teachers in teacher-child interaction, and the "adult" language expression of teachers in teaching activities.
