“…They have also introduced the concept of denoising the noisy signals by discrete WT and inverse WT. Jeong and Jang (2000) applied WT for analysis of dispersive plate waves using the Gabor wavelet. They indicated that dispersion of flexural mode can be well predicted by their proposed method even for anisotropic plate.…”

Structural damages are often associated with under-performance of an engineering system. Hence localisation of such damages, followed by remedial measures, is the key to ensure proper functioning of the structures during their design lives. Acoustic emission (AE) technique is one of the effective non destructive evaluation (NDE) techniques for damage localisation. The present study makes an effort to review the existing literature on this technique under a few broad categories and discuss chronological advancements in each such category. The advantages and drawbacks of each method are deliberated and further scopes of research are pointed out.

“…Different authors demonstrated, that it is possible to extract accurately the arrival times of AE signals with the results of WT (Grosse et al, 2002;Hamstad, 2004;Hamstad et al, 2003;Jeong et al, 2000;Jiao et al, 2004). More important information is possible to obtain from peak stress.…”

Engineering has a very important role in the development of non-destructive monitoring of orthopaedical systems allowing the evaluation of its integrity. Sir John Charnley revolutionized the field of joint arthroplasty in the 1960s with the development of the total hip replacement. He replaced the diseased hip joint with a steel femoral component and a plastic acetabular socket cup combination, both fixed into the bone using a self-curing acrylic cement, polymethylmethacrylate (PMMA) (Browne et al, 2005). That way, he has restored some of the most problematic joints in the human body. The placement of the metal implant in the channel open in the femoral bone without using cement or by mechanical attack, called a non cemented arthroplasty, came into use in an effort to solve the problem. A study about prostheses reviews, between 1979 and 2005, show that's were higher in non-cemented prosthesis, leading to studies on new forms of interface bone/metal. The growth of cemented arthroplasties has been observed since 2005. By Ramos (Ramos et al, 2005), cemented arthroplasty is one of the most successful surgical techniques in orthopaedics. However, the cemented prosthesis has a tendency to fray during the time of their life due to stress and fatigue of the cement material leading to it cracking. The growing importance of different Total Hip Arthroplasty (THA) studies is due to increased life expectancy of the population and its social and clinical relevance. Interdisciplinary THA studies such as: biomechanics (Bergmann et al, 2001;Fonseca et al, 2010;Nabais, 2006;Ramos et al, 2005; Stolk et al, 2006;Teixeira et al, 2008; Vieira, 2004); finite element analysis (Bachtar et al, 2006;Nizam Ahmad et al, 2006;Ridzwan et al, 2006) and acoustic emission monitoring (Browne et al, 2005;Cristofolini et al, 2003;Davies et al, 1996;Franke et al, 2004;Gueiral, 2008;Qi et al, 2005;Qi, 2000;Rowland et al, 2004) have been published. Research has been done to improve the performance of artificial implants, addressing factors such as geometry, materials, cements, and other surgical techniques that directly or indirectly, might influence the performance and success of cemented arthroplasty. Although the lifetime of a THA is between 10 and 15 years, there are factors that lead to loss of prosthesis such as the separation of the femoral prosthesis due to the splitting of connection between the implant/cement and cement/bone. The human body responds through its immune system causing inflammation and pain in osseous structure, which in most cases leads to the replacement of the prosthesis.

“…The distance between the two sensors was 420 mm. By using the wavelet transformation technique [14], the arrival times of the incident waves to the two sensors were determined and the wave propagation speed of S0 mode at f=100 kHz was estimated as 6210 m/s. To verify the experimental results, the theoretical wave speed of the S0 mode was estimated based on the transfer matrix method [15].…”
