  • Remaining Useful Life Prediction for Multiple-Component Systems Based on a System-Level Performance Indicator
    IEEE ASME Transactions on Mechatronics, 2018
    Co-Authors: Leonardo Ramos Rodrigues
    Abstract:

    Most prognostics and health management publications focus on the development of algorithms to monitor and estimate the health condition of individual components. However, estimating the remaining useful life (RUL) of complex systems comprising multiple components is a more relevant topic for the industry. An accurate system-level RUL prediction can be used as a powerful decision support tool to help industry practitioners reduce operational costs and increase availability of systems. This paper presents a method to estimate the RUL of multiple-component systems based on health monitoring information regarding each component in the system under consideration. The proposed method relates the health factors of each component to its performance. Then, a system-level performance indicator is computed based on the performance of each component and a system Architecture Function that describes the relations among different components within the system. The system-level RUL is then estimated based on the extrapolation of the system-level performance indicator and a known failure threshold. In the proposed method, a system failure is not necessarily connected with a component failure. We present two case studies to illustrate the application of the proposed method: 1) a simplified aircraft hydraulic system containing multiple pumps; and 2) an aircraft air conditioning system containing different components.

  • Network Devices Fault Diagnosis Based on Rough Set Theory
    2010 International Conference on Internet Technology and Applications, 2010
    Co-Authors: Jifeng Yang
    Abstract:

    In this paper, a network devices fault diagnosis system based on Rough Set theory is introduced. It describe the design of fault diagnosis system from theory background, system Architecture, Function module and presents the basic principle, specific algorithm and steps to set up model which forms the fault diagnosis system by MIB data. It is proved effective for the system to diagnose the network devices via fault signals.

  • Mitochondrial ATP synthase: Architecture, Function and pathology
    Journal of Inherited Metabolic Disease, 2012
    Co-Authors: An I Jonckheere, Jan A M Smeitink, Richard J. Rodenburg
    Abstract:

    Human mitochondrial (mt) ATP synthase, or complex V consists of two Functional domains: F_1, situated in the mitochondrial matrix, and F_o, located in the inner mitochondrial membrane. Complex V uses the energy created by the proton electrochemical gradient to phosphorylate ADP to ATP. This review covers the Architecture, Function and assembly of complex V. The role of complex V di-and oligomerization and its relation with mitochondrial morphology is discussed. Finally, pathology related to complex V deficiency and current therapeutic strategies are highlighted. Despite the huge progress in this research field over the past decades, questions remain to be answered regarding the structure of subunits, the Function of the rotary nanomotor at a molecular level, and the human complex V assembly process. The elucidation of more nuclear genetic defects will guide physio(patho)logical studies, paving the way for future therapeutic interventions.
