Data and code for: Design-Time Sensor Configuration for Single-Sensor Loss in Hydraulic Fault Diagnosis: A Reproducible Held-Out Evaluation

This record contains derived data, analysis code, configuration files, predictions, archived results and supporting documentation for the manuscript “Design-Time Sensor Configuration for Single-Sensor Loss in Hydraulic Fault Diagnosis: A Reproducible Held-Out Evaluation” by Zhifeng Yang and Xiaoxi Fan. The study uses the public UCI Condition Monitoring of Hydraulic Systems dataset, originally created by Nikolai Helwig, Eliseo Pignanelli and Andreas Schütze. The original dataset is available at https://doi.org/10.24432/C5CW21 under the Creative Commons Attribution 4.0 International license. The analyses use 2,205 operating cycles, 14 physical sensor channels and four component diagnosis tasks covering the cooler, valve, pump and accumulator. The archive includes materials for the frozen held-out evaluation of sensor configurations, supplementary whole-channel imputation analyses and catalogue-price calculations. It also contains configuration and partition records, per-cycle predictions, statistical outputs, provenance records and documentation. Supplementary analyses performed after the primary test are identified as post-hoc and exploratory. Historical development scripts are retained as provenance records. They have not all been validated as an executable end-to-end workflow under the current archive structure. The archive should not be interpreted as a guarantee that every historical analysis and manuscript figure can be regenerated through a single command. No new physical experiments were conducted. Complete single-channel loss was emulated computationally using recorded measurements. The findings are limited to the original test rig and the specified evaluation conditions.
