This book aims to provide the basic theory of fractional calculus and its applications based on practical schemes and approaches, illustrated with applicable engineering and technical examples, especially focusing on the fractional-order controller design. In the development of this book, the essential theorems and facts in the first two chapters are proven with rigorous mathematical analyses. In addition, the commonly used definitions of Grunwald-Letnikov, Riemann-Liouville, Caputo, and Miller-Ross fractional derivatives are introduced with their properties proved and linked to fractional-order controller design. The last chapter presents several enlightening scenarios of fractional-order control designs, for example, the suppression of machining chatter, the nonlinear motion control of a multilink robot, the simultaneous tracking and stabilization control of a rotary inverted pendulum, and the idle speed control of an internal combustion engine (ICE).

As online learning has become firmly embedded within the higher education landscape, considerable concerns arise, particularly as it relates to the quality of this mode of instruction. Although the quantity of literature regarding online education is expanding, a more in-depth and broader review of factors that may lead to quality online education is needed. Furthermore, in order to provide effective and quality online education, studies on students¿ perceptions on quality issues are needed, therefore the primary objective of this study is to examine students¿ perceptions regarding the quality of online courses and to determine the factors that impact students¿ perceptions. The study employs IHEP Quality benchmarks utilizing peer interactions, instructor feedback, course structure, and student support as predictor variables. Findings of this study provide valuable information that can serve online instructors and administrators in providing more effective online education. Recommendations for practice as well as for further research are provided.

Improvement of injection molding processes remains a topic of great interest in both industry and research institutions. This book introduces the analysis of the molding process from a systems technology point of view.

Fluctuation Mechanism and Control on System Instantaneous Availability facilitates the development of modeling and identification skills for both theoretical research and applications. Supplying an overall summary of current research results in fluctuation analysis of instantaneous availability, it covers the theory, methodology, and specific engineering implementation required to conduct equipment instantaneous availability analysis. Presenting practical methods and tools, it describes how to control the matching transition of new equipment systems as a result of interactions among sub-systems.
