The pulp and paper industry is comprised of facilities that manufacture corrugated paper, flake or particle board pressing, woven or fiber spinning, and general craft paper. The unique aspect of pulp and paper is the integrated complexity in medium to large- sized plant operations. Typically, people think about the paper end of the ...

The oil and gas pipeline industry has been under close scrutiny for a long time. It leads the way as one of the most regulated industries in the world, and for good reason.  With so many safety-related, social and environmental factors at stake, comprehensive regulation ensures rigorous standards for the design, construction, operation and maintenance of O&G pipeline systems. Global ...

The monitoring of the acoustic emissions (AEs) due to rock fracturing allows the detection of the rockfall precursor signals, leading to a strong improvement of the real time assessment of the induced risk. A network of piezoelectric sensors (PZTs) provides reliable AE data, as testified by a series of applications in non–destructive testing, but PZTs are strongly affected by lightings and ...

Nowadays, one of the most valuable criteria of vehicle quality assessment is based on acoustic emission levels. A vehicle is judged comfortable depending on the noise levels transmitted inside. Consequently, there is a general attention to the design criteria aimed at improving the structural acoustic behaviour, to comply with the increasingly restrictive ergonomic standard. Therefore, it is ...

A regression source location algorithm is developed to locate microcracks in bovine bone samples. Bone samples measuring 60 mm long, 22 mm wide and 5.5 mm thick were harvested from bovine femora. Artificial acoustic emission sources were created on the bone samples. The known location of these acoustic emission sources and the recorded arrival times at four acoustic emission sensors were used to ...

Over the last four to five decades, application of fibre-reinforced plastics have seen tremendous growth. In spite of the complexity of their behaviour, development of composite pressure chambers has significantly contributed to the spectacular progress in the strength to weight ratio. This paper presents an overview on the acoustic emission (AE) developments towards failure pressure prediction ...
