A Systematic AI‐Based Paradigm for Classifying Hybrid Electric Vehicle Spare Parts Using Their Price and Demand

Journal of Engineering, Volume 2026, Issue 1, 2026.
With the rapid growth of the hybrid electric vehicle (HEV) market, stakeholders must refine after‐sales logistics, particularly spare parts (SPs) provisioning. Adequate forecasting of demand and pricing underpins these efforts. This paper presents a feedforward artificial neural network (FF‐ANN) that, drawing on 15 predictor variables, assigns each SP ...

Research on Multidimensional Application Effect Evaluation of Pipeline Fiber‐Optic Early Warning System

Journal of Sensors, Volume 2026, Issue 1, 2026.
Despite the continuous improvement in the technical performance of fiber‐optic early warning systems, their actual application results in preventing third‐party intrusion into oil and gas pipelines are often less than ideal. This issue stems largely from the lack of comprehensive postdeployment evaluation methodologies, making it difficult to identify ...

Bayesian Estimation of Failure Rates in Two‐Unit Series Systems: Analyzing Train Brake Systems

Modelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
This study investigates the failure rates of train braking systems, recognizing their pivotal role in vehicle performance. Using a Bayesian estimation approach, the study focuses on parameterizing the failure rates of two brakes arranged in series to form a two‐unit train brake system. A bivariate exponential model, accommodating varying failure rates,
