Copula-based statistical health grade system against mechanical faults of power transformers

Hu, Chao; Wang, Pingfeng; Youn, Byeng D.; Lee, Wook-Ryun; Yoon, Joung Taek (IEEE-INST Electrical Electronics Engineers Inc, 2012-10)

A health grade system against mechanical faults of power transformers has been little investigated compared to those for chemical and electrical faults. This paper thus presents a statistical health grade system against ...
Deep belief network based state classification for structural health diagnosis

Tamilselvan, Prasanna; Wang, Yibin; Wang, Pingfeng (IEEE, 2012)

Effective health diagnosis provides multifarious benefits such as improved safety, improved reliability and reduced costs for the operation and maintenance of complex engineered systems. This paper presents a novel ...
Ensemble of data-driven prognostic algorithms for robust prediction of Remaining Useful Life

Hu, Chao; Youn, Byeng D.; Wang, Pingfeng; Yoon, Joung Taek (Elsevier, 2012-03)

Prognostics aims at determining whether a failure of an engineered system (e.g., a nuclear power plant) is impending and estimating the remaining useful life (RUL) before the failure occurs. The traditional data-driven ...
Failure Diagnosis Using Deep Belief Learning based Health State Classification

Tamilselvan, Prasanna; Wang, Pingfeng (Elsevier, 2013-03-13)

Effective health diagnosis provides multifarious benefits such as improved safety, improved reliability and reduced costs for operation and maintenance of complex engineered systems. This paper presents a novel multi-sensor ...
A generic probabilistic framework for structural health prognostics and uncertainty management

Wang, Pingfeng; Youn, Byeng D.; Hu, Chao (Elsevier, 2012-04)

Structural health prognostics can be broadly applied to various engineered artifacts in an engineered system. However, techniques and methodologies for health prognostics become application-specific. This study thus aims ...
A nested extreme response surface approach for time-dependent reliability-based design optimization

Wang, Zequn; Wang, Pingfeng (ASME, 2012-12)

A primary concern in practical engineering design is ensuring high system reliability throughout a product's lifecycle, which is subject to time-variant operating conditions and component deteriorations. Thus, the capability ...
A New Approach for Reliability Analysis with Time-Variant Performance Characteristics

Wang, Zequn; Wang, Pingfeng (Elsevier, 2013-03-01)

Reliability represents safety level in industry practice and may variant due to time-variant operation condition and components deterioration throughout a product life-cycle. Thus, the capability to perform time-variant ...
