Swarm system, also known as multi-agent system, refers to a system composed of multiple subsystems (agents) with certain communication, calculation, decision-making, and action capabilities through local information interaction, such as a group of unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), satellites, etc. Formation tracking control of swarm systems is an important technical support and approach for the emergence of swarm intelligence at motion control level. By applying formation tracking control, swarm system agents can adjust their relations in the state or output space through neighboring information interaction, and then the swarm system can achieve favorable space-time conditions for many cooperative tasks such as source seeking, target enclosing, and surveillance. Thus, complex missions can be performed efficiently or cost-effectively. In cross-domain collaborative applications, including air-ground coordination and air-sea coordination, swarm systems are usually composed of several heterogeneous agents, and swarm intelligence can be enhanced by complementary functions of different agents. How to achieve time-varying formation tracking for heterogeneous swarm systems is crucial for cross-domain coordination, which has important theoretical value and practical significance. This important book presents a systematic theoretical approach and control framework on the time-varying formation tracking for high-order heterogeneous swarm systems. Distributed controller design and stability analysis of closed-loop systems for several specific formation tracking problems are provided. Furthermore, the proposed control approaches are applied to practical cooperative experiment platforms composed of UAVs and UGVs, and several formation tracking experiments are carried out to further verify the effectiveness of the theories.

"Advances in Filament Yarn Spinning of Textiles and Polymers" reviews the different types of spinning techniques for synthetic polymer-based fibers, and issues such as their effect on fiber properties, including melt, dry, wet, and gel spinning.

Synthetic polymer-based fibers are used in a great variety of consumer and industrial textile applications ranging from clothing to home furnishings to surgical procedures. This book explores how a wide array of spinning techniques can be applied in the textile industry. Part one considers the fundamental structure and properties of fibers that determine their behavior during spinning. The book then discusses developments in technologies for manufacturing synthetic polymer films to produce different fibers with specialized properties. Part two focuses on spinning techniques, including the benefits and limitations of melt spinning and the use of gel spinning to produce high-strength and high-elastic fibers. These chapters focus specifically on developments in bi-component, bi-constituent, and electro-spinning, in particular the fabrication of nanocomposite fibers. The final chapters review integrated composite spinning of yarns and the principles of wet and dry spinning.

This collection is an important reference for a wide range of industrial textile technologists, including spinners, fabric and garment manufacturers, and students of textile technology. It is also of great interest for polymer scientists.

This book gives an overview on the molecular structures (MS) and crystal structures (CS) of rare earth metal (REM) complexes with a series of aminopolycarboxylic acid (APCA) ligands, which are nitrilotriacetic acid (nta), ethylenediamine-N, N, N', N'-tetraacetic acid (edta), diethylenetriamine-N, N, N', N'', N''-pentaacetic acid (dtpa), triethylenetetramine-N, N, N', N'', N''', N'''-hexaacetic acid (ttha) trans-1,2-cyclohexanediamine-N, N, N', N'-tetraacetic acid (cydta) and 1,3-propylenediamine-N, N, N', N'-tetraacetic acid (pdta). Among the REM complexes with the same APCA ligand, the coordination law (CL) of coordination numbers (CN) and geometrical conformation (Ge are discussed with emphasis. The research results indicate that the CN and GC of REM complexes with various APCA ligands mainly depend on the ionic radii and electronic configurations of central REM ions, the shape of APCA ligands as well as the category of counter ion.

The main purpose of this book is to explore the influences of reform on changes in China's economic relations with Japan after the late 1970s. There are three reasons for investigating the links between Chinese reform and bilateral economic relations at this particular juncture in history. First, in the past two decades reform has meant that China has enjoyed faster economic growth then Japan. This has transformed the pattern of bilateral economic relations, hitherto characterised by an industrial Japanese economy and a resource-based Chinese economy, a result of Japan's successful industrialisation and China's failure to industrialise in the previous hundred years. Second, reform has brought about the deepening of the interdependence between the Chinese economy and the world economy. Through links with the world economy, the Chinese economy has not only come to rely on foreign countries for technology, capital, markets and management skills, but has itself become a growth pole, exerting a strong impact on world economic growth. In the reform era, economic relations between China and Japan have been woven into regional and global economic networks of trade an investment. Third, reform has transformed the management of China's domestic and external economic activities.
