For the many different deterministic non-linear dynamic systems (physical, mechanical, technical, chemical, ecological, economic, and civil and structural engineering), the discovery of irregular vibrations in addition to periodic and almost periodic vibrations is one of the most significant achievements of modern science. An in-depth study of the theory and application of non-linear science will certainly change one's perception of numerous non-linear phenomena and laws considerably, together with its great effects on many areas of application. As the important subject matter of non-linear science, bifurcation theory, singularity theory and chaos theory have developed rapidly in the past two or three decades. They are now advancing vigorously in their applications to mathematics, physics, mechanics and many technical areas worldwide, and they will be the main subjects of our concern. This book is concerned with applications of the methods of dynamic systems and subharmonic bifurcation theory in the study of non-linear dynamics in engineering. It has grown out of the class notes for graduate courses on bifurcation theory, chaos and application theory of non-linear dynamic systems, supplemented with our latest results of scientific research and materials from literature in this field. The bifurcation and chaotic vibration of deterministic non-linear dynamic systems are studied from the viewpoint of non-linear vibration.
The surge in energy prices since Russia’s invasion of Ukraine has reduced the energy-intensive sector’s production in Germany, although the non-energy intensive sector’s production has held up thanks in part to firms’ efforts to improve energy efficiency. Energy prices are expected to remain elevated in the foreseeable future, compared to pre-war levels, adversely affecting firms’ productivity and thus lowering Germany’s potential output. Economic modeling suggests that this effect could be around 11⁄4 percent of GDP in staff’s baseline, with some uncertainty around this estimate, depending on the ultimate magnitude of the energy price shock and the degree to which increased energy efficiency can mitigate it. Policies can promote effective adjustment to the shock by increasing productivity and maintaining strong price incentives to conserve energy and invest in renewable energy production.
This book gives a comprehensive and systematic review of secure compressive sensing (CS) for applications in various fields such as image processing, pattern recognition, Internet of things (IoT), and cloud computing. It will help readers grasp the knowledge of secure CS and its applications, and stimulate more readers to work on the research and development of secure CS. It discusses how CS becomes a cryptosystem, followed by the corresponding designs and analyses. The application of CS in multimedia data encryption is presented, in which the general design framework is given together with several particular frameworks including parallel CS, involvement of image processing techniques, and double protection mechanism. It also describes the applications of CS in cloud computing security and IoT security, i.e., privacy-preserving reconstruction in cloud computing and secure low-cost sampling in IoT, respectively.
This book focuses on the current internal and external situation China is facing both from a macro perspective and a theoretical height, and puts forward practical development strategies and diplomatic ideas. It is of great methodological significance. At home, the development thought after the conclusion of the hundred-year change is the guiding thought for China's further development, and abroad, the international communication and the construction of international order highlighted by the hundred-year change also have important reference significance for the world's development.
Many books have been written about the design, construction, and maintenance of valvetrains, but until now, information has been scattered and difficult to find. This comprehensive book will serve as your single resource providing a systematic introduction to valvetrain systems and components. Focusing on the fundamental concepts, this book enables you to appreciate design and material considerations, while at the same time understanding the difficulties in designing valvetrains to satisfy functional requirements and manufacturing challenges.
