Another approach to vibrational analysis of stepped structures

Author: Fedotov, I ; Joubert, S ; Marais, J ; Shatalov, M Date: 2006 In this paper a model of an N-stepped bar with variable Cross-sections coupled with foundation by means of lumped masses and springs is studied. It is assumed that the process of vibrations in each section of the bar is described by a wave ... Read more
Gyroscopic effects in vibrating fluid-filled spheres subjected to inertial rotation

Author: Shatalov, MY ; Joubert, SV ; Coetzee, CE ; Fedotov, I Date: Jul 2007 In symmetric distributed structures subjected to vibration and an inertial rotation, the vibrating patterns turn in the direction of revolution at a rate proportional to the inertial angular rate. This effect has numerous applications in ... Read more
Investigation of gyroscopic effects in vibrating fluid-filled cylinders subjected to axial rotation

Author: Shatalov, MY ; Joubert, SV ; Voges, E Date: Jul 2007 Vibrating patterns of distributed oscillating structures, subjected to rotation, also turn in the direction of inertial revolution but with different angular rates, which depend on the geometry of the structures, the number of modes, etc. ...

Quality-based fingerprint segmentation

Author: Mngenge, NA ; Nelwamondo, Fulufhelo V ; Malumedzha, T ; Msimang, N Date: Jun 2012 The need for segmentation of low quality fingerprints in forensics, high security and civilian applications is constantly increasing. Most segmentation algorithms proposed in the literature normally deal with separation of the background ... Read more
Use of eigenvectors in the solution of the flutter equation

Author: Van Zyl, Louwrens H Date: Jul 1993 The use of eigenvectors to assign eigenvalues to modes for the p-k formulation of the flutter equation is described. The procedure has the potential to overcome some of the problems of the determinant iteration procedure to solve the flutter ... Read more
