The main objective of this study is to assess the specific capabilities of the defect energy parameter technique for global damage detection developed by Saleeb and coworkers. The feature extraction is the most important capability in any damage-detection technique. Features are any parameters extracted from the processed measurement data in order to enhance damage detection. The damage feature extraction capability was studied extensively by analyzing various simulation results. The practical significance in structural health monitoring is that the detection at early stages of small-size defects is always desirable. The amount of changes in the structure's response due to these small defects was determined to show the needed level of accuracy in the experimental methods. The arrangement of fine/extensive sensor network to measure required data for the detection is an "unlimited" ability, but there is a difficulty to place extensive number of sensors on a structure. Therefore, an investigation was conducted using the measurements of coarse sensor network. The white and the pink noises, which cover most of the frequency ranges that are typically encountered in the many measuring devices used (e.g., accelerometers, strain gauges, etc.) are added to the displacements to investigate the effect of noisy measurements in the detection technique. The noisy displacements and the noisy damage parameter values are used to study the signal feature reconstruction using wavelets. The enhancement of the feature extraction capability was successfully achieved by the wavelet theory.

Gopi Krishna, born and reared in a rural area of Kashmir, achieved Cosmic Consciousness at the age of 34. This is such a rare achievement that it is unlikely that there have been more than five or six similar achievements over the past several hundred years. His more than 17 books, and many discourses, are considered the bible on the subject of Super-Consciousness and brain evolution. This book makes it absolutely clear as to what is Enlightenment, or Illumination, or Super-Consciousness, which is crucial for any aspirant who wishes to attain Higher Consciousness. Unless one knows the target of his or her spiritual practices, how can he hope to achieve that target. It is the same with any exercise or attainment. One must know in advance what it is that he is striving for. This book describes the goal. No other book does this as clearly and definitively as "The Real Nature of Mystical Experience."

A classic first-person account of spiritual awakening, now in a revised and expanded edition. Krishna tells of his awakening to kundalini, a spiritual force said to be asleep in every human being which finds expression in the form of spiritual knowledge, mystical vision, psychic powers and enlightenment.
