- "The book is a systematic treatment of several classes of analytical techniques and applications in nonlinear random vibration. The classes include exact solution of the Fokker-Planck-Komogorov equation, methods of statistical linearization, statistical nonlinearization techniques, methods of stochastic averaging, truncated hierarchy and other techniques. Many examples of the more popular classes, such as methods of statistical linearization, statistical nonllinearization techniques and methods of stochastic averaging, are presented. Many references are quoted. A special feature of the monograph is its incorporation of detailed steps in many examples. Thus, it is suitable for self-study, advanced level graduate students, and research scientists and engineers"--
