Analysis of Changes on Mean Particle Size in a Fluidized Bed using Vibration Signature
Vibration signals were measured in a lab-scale fluidized bed to investigate the changes in particle sizes. Experiments were carried out in the bed with a different mass fraction of coarser particles at different superficial gas velocities, and probe heights. The S-statistic test evaluates the dimensionless squared distance between two attractors reconstructed from time series of vibration signa...
متن کاملNonlinear vibration signature analysis of a rotor supported ball bearings
The dynamic behaviour of a high speed balanced rotor supported on deep groove ball bearings (SKF-6205) has been studied by numerically simulated results. Since, internal radial clearance (IRC) is inevitably present in all class and types of bearing, in this paper it (IRC-C3) is considered as main source of nonlinearity with speed as control parameter. The complex mathematical model simulates no...
متن کاملVibration Analysis by Laser Interferometry Techniques
The application of laser interferometry techniques to study the dynamic behaviour of structural components is described. Being a non contact field technique, it allows the measurement of a dynamic displacement fields without need of additional fitting of transducers, which would change the mass of the structure. Image processing techniques are already available to reduce the time invested in th...
متن کاملAnalysis of pattern recognition techniques for in-air signature biometrics
Keywords: Biometrics Signature Accelerometer Hidden Markov models Bayes Dynamic time warping As a result of advances in mobile technology, new services which benefit from the ubiquity of these devices are appearing. Some of these services require the identification of the subject since they may access private user information. In this paper, we propose to identify each user by drawing his/her h...
متن کاملVibration analysis by speckle techniques in real time.
Vibration analysis in quasi-real time is studied by recording the time-averaged speckle pattern in a bismuth silicon oxide crystal (Bi(12)SiO(20)). When the crystal is illuminated with a spherical wave, the spatially structured information from the time-averaged speckle pattern leads to fringes in the Fraunhofer plane. No storage device is required when the appropriate wavelength is chosen for ...
