Modelling the input-output behaviour of piezoelectric structural health monitoring systems for composite plates

This paper investigates the input-output characteristics of structural health monitoring systems for composite plates based on permanently attached piezoelectric transmitter and sensor elements. Using dynamic piezoelectricity theory and a multiple integral transform method to describe the propagating and scattered flexural waves an electro-mechanical model for simulating the voltage input-output transfer function for circular piezoelectric transmitters and sensors adhesively attached to an orthotropic composite plate is developed. The method enables the characterization of all three physical processes, i.e. wave generation, wave propagation and wave reception. The influence of transducer, plate and attached electrical circuit characteristics on the voltage output behaviour of the system is examined through numerical calculations, both in frequency and the time domain. The results show that the input-output behaviour of the system is not properly predicted by the transducers' properties alone. Coupling effects between the transducers and the tested structure have to be taken into account, and adding backing materials to the piezoelectric elements can significantly improve the sensitivity of the system. It is shown that in order to achieve maximum sensitivity, particular piezoelectric transmitters and sensors need to be designed according to the structure to be monitored and the specific frequency regime of interest.

Early warning signs in postgraduate research education: a different approach to ensuring timely completions

Recent government intervention in research higher degree policy across the globe has sharpened universities' focus on the quality of their students' research education experience and on timely completion rates. Studies have sought to highlight the factors that predict research students' timely completion of their studies. Many universities have sought to tighten their selection processes as a way of improving completion rates, even verging on adopting a risk analysis approach to selecting students. Instead this paper takes a preventative, interventionist approach to improving timely completions. It explores how experienced supervisors detect and deal with early warning signs that their research students are experiencing difficulty. It also investigates the wide range of reasons some students nominate for not discussing these difficulties directly with their supervisors. It proposes that supervisors may be able to improve timely completions if they are aware of these reasons and if they adopt a range of explicit pedagogical strategies to support students' learning.

Student expectations of TESOL programs: Student and teacher perspectives

Most practitioners teaching English to speakers of other languages (TESOL) will agree that students come with some expectations about course content and teaching methodology and that these expectations play a vital role in student motivation and learning. However, the study of student expectations has been a surprising omission from Second Language Acquisition research. In the studies reported here, the authors develop a model of student expectations by adapting the Expectation Disconfirmation paradigm, widely used in consumer psychology. Student and teacher perspectives on student expectations were gathered by interviews. Responses shed light on the nature of expectations, factors causing expectations and effects of expectation fulfilment (or lack of it). The findings provide new avenues for research on affective factors as well as clarify some ambiguities in motivational research in second language acquisition. The model presented here can be used by teachers or institutions to conduct classroom-based research, thus optimising students' learning and performance, and enhancing student morale.
