INTRODUCTION Worry and rumination are two forms of repetitive thinking characterised by their negative content and apparently uncontrollable nature. Although worry and rumination share common features and have been conceptualised as part of a transdiagnostic repetitive negative thinking (RNT) process, it remains unclear whether they share the same underlying cognitive mechanisms. This multisess...

1 IEEEAC paper #1311, Updated September 19, 2002 Abstract— Increasing levels of machinery automation for systems health monitoring are providing operators with larger amounts of raw data. However, transforming massive amounts of data into information useful for effective condition-based maintenance (CBM) remains an arduous task. New technology is needed to continually monitor machinery, to iden...

In this work the three disciplines of condition based maintenance (CBM), structural health monitoring (SHM) and prognostics and health management (PHM) are described. Then the characteristics of the disciplines are compared, which leads to a clear insight in the commonalities, but also in the difference in objectives and scope of the three disciplines. The disciplines are then demonstrated usin...

Experience with the growing number of large-scale and long-term case-based reasoning (CBR) applications has led to increasing recognition of the importance of maintaining existing CBR systems. Recent research has focused on case-base maintenance (CBM), addressing such issues as maintaining consistency, preserving competence, and controlling case-base growth. A set of dimensions for case-base ma...

Abstract. New “enlightened” and holistic maintenance strategies are shaping the industrial world from inside, providing intelligent focused solutions where high availability, reliability safety required. Maintenance planning scheduling is an extremely daunting multi-faceted task which involves competences fairly different fields: customer support, quality, engineering, production, RAMS, cost es...

This article is a case study of the maintenance required to the case base of a commercially fielded case-based reasoning (CBR) system that provides support for HVAC engineers enabling them to better specify HVAC installations. The article briefly describes the system and details how the case base grew rapidly, causing a problem of case redundancy. A simple algorithm to identify and remove redun...

Since last years Case Base Reasoning (CBR) field has been growing, and Case Base Maintenance (CBM) is getting more important. Recent research has focused on case-base maintenance, addressing such issues as maintaining consistency, preserving competence, and controlling case-base grow. A set of dimensions for case-base maintenance proposed by Leake and Wilson, provides a framework for understand...

With the development of Internet things, big data, and AI leading 4th industrial revolution, it has become possible to acquire, manage, analyze vast diverse condition signals from various machinery facilities. In addition, been revealed that large amounts acquired facilities can be utilized for fault diagnosis. Currently, while data-driven diagnosis techniques applicable are being developed, tr...

Flexible case-base maintenance (FCBM) and adaptation-guided feature deletion (AGFD) extend case-base maintenance (CBM) research. FBCM examines superficial properties of cases and their features such as the size of a case or the rarity of a feature. Then it deletes either entire cases, or components of cases, measuring competence by the number of problems solved and measuring size by the number ...
