0925-0042 efficients, and a second part, relatively small compared with the first, containing nonlinear terms. Such a system is said to be weakly nonlinear. The small terms rendering the system nonlinear are referred to as perturbations. A weakly nonlinear system is called quasi-linear and is governed by quas

Averaging Method,sides of complicated differential equations by averaged functions which did not explicitly contain either the time t or rapidly changing parameters of the system. The resulting equations were either exactly integrable or greatly simplified, and could be used to draw important qualitative and quantitative conclusions about the motion.

Book 2023es many different engineering disciplines. This book explores the new technology landscape that will have the direct impact on production-related sectors, individually and in combination with different disciplines. A major driver for this actual research is the efficiency, many times connected with a focus on environmental sustainability. .
