  • Acoustic emission source localisation on bone using multiple regression

    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 ...

  • Rockfall precursor detection based on rock fracturing monitoring by means of optical fibre sensors

    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 ...

  • Oil Analysis for Pulp and Paper

    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 ...
