Vibration monitoring of rolling element bearings is possibly the most established diagnostic technique for rotating machinery. The application of Acoustic Emission (AE) for bearing diagnosis is gaining ground as a complementary diagnostic tool; however, limitations in the successful application of the AE technique have been partly due to the difficulty in(More)
Calls for organizational culture change are audible in many health care discourses today, including those focused on medical education, patient safety, service quality, and translational research. In spite of many efforts, traditional “top–down” approaches to changing culture and relational patterns in organizations often disappoint. In an effort to better(More)
Continuous rubbing between the shaft and surrounding seals or end-glands of electricity generating turbine units can escalate into very severe vibration and costly rotor damage. Therefore such rotor–stator contacts require early diagnosis so as to minimize the financial consequences of any unplanned shutdowns. Acoustic emissions (AEs) or stress wave(More)
The social environment or “informal” curriculum of a medical school profoundly influences students’ values and professional identities. The Indiana University School of Medicine is seeking to foster a social environment that consistently embodies and reinforces the values of its formal competency-based curriculum. Using an appreciative narrative-based(More)
Pumps play a significant role in industrial plants and need continuous monitoring to minimize loss of production. This paper investigates the application of Acoustic Emission (AE) for detecting incipient cavitation. In addition this paper presents results from an ongoing programme to ascertain the applicability of the AE technique for determining the best(More)
Acoustic emission (AE) monitoring is a technique of growing interest in the field of nondestructive testing (NDT). The use of AE devices to monitor the health of structural components is currently limited by the cost of AE equipment, which prohibits the permanent placement of AE devices on structures for the purposes of continuous monitoring and the(More)
Asset Health Management (AHM), supported by condition monitoring (CM) and performance measuring technologies, together with trending, modelling and diagnostic frameworks, is not only critical to the reliability of high-value machines, but also to a companies Overall Equipment Efficiency (OEE), system safety and profitability. In addition these protocols are(More)
Structural heath monitoring of engineering structures is of growing interest due to increased complexity of such structures and the ability to schedule maintenance when it is needed thus preventing unnecessary work or preventing failure. One such method for monitoring the structural health of large scale structures is through the detection of Acoustic(More)
