A novel multifunctional self-validating sensor functional model is proposed for evaluation, improvement, and forecast of measurement value reliability. This paper presents a detailed introduction of main content-self-validating function, especially the quantitative health evaluation and remaining using life forecasting. As a fundamental self-validating(More)
Current practice for diagnosing nasopharyngeal carcinoma (NPC) is based on invasive tissue biopsy. This study aims to explore the feasibility of using Raman spectroscopy to differentiate cancerous and non-cancerous nasopharyngeal tissue smears, expecting to realize minimal invasive diagnosis using smears from in vivo mucosa tissue by Raman spectroscopy.(More)
Multiple different quantities are often measured by the multifunctional sensor in industrial applications. The sensor may not be truly healthy or fault-free, which could reduce the reliability of measurement results. In this paper, a new prototype of multifunctional self-validating sensor was put forward, and detailed intelligent functions were illustrated(More)
Aiming at the desired status self-validation of traditional multifunctional sensor, a novel multifunctional self-validating sensor functional model is employed to improve the measurement reliability. Detailed self-validating functions which consist of faults detection, isolation and recovery, validated uncertainty estimation and health levels evaluation of(More)
A novel strategy by using relevance vector machine (RVM) coupled with fuzzy comprehensive evaluation method is proposed for the health evaluation of engine test-bed system. Based on our previous work, the concept of health reliability degree (HRD) is reviewed to indicate a quantitative health level from the perspectives of single parameter, some subsystems(More)
