Distributed Coordination of Multi-agent Networks introduces problems, models, and issues such as collective periodic motion coordination, collective tracking with a dynamic leader, and containment control with multiple leaders, and explores ideas for their solution. Solving these problems extends the existing application domains of multi-agent networks; for example, collective periodic motion coordination is appropriate for applications involving repetitive movements, collective tracking guarantees tracking of a dynamic leader by multiple followers in the presence of reduced interaction and partial measurements, and containment control enables maneuvering of multiple followers by multiple leaders.

This Element introduces the areas that second language (L2) pragmatics research has investigated. It begins with a theme-based review of the field with respect to L2 pragmatics learning, teaching, and assessing. The section on pragmatics learning examines studies on learners' pragmatic production and perception, and analyzes research modalities in this field. The section on pragmatics teaching examines the effects of and different approaches to L2 pragmatics instruction; and the section on pragmatics assessing examines the aspects involved in testing learners' pragmatic competence, and studies on issues related to validity and rating in pragmatics assessing. The Element then analyzes studies exploring learners' cognitive processes during pragmatic performance, and case studies are provided to showcase two ongoing projects, one investigating advanced learners' self-praise on social media and the other investigating lingua franca pragmatics among children. Finally, the Element offers some topics and questions for future research in L2 pragmatics.

Information consensus guarantees that robot vehicles sharing information over a network topology have a consistent view of information critical to the coordination task. Assuming only neighbor-neighbor interaction between vehicles, this monograph develops distributed consensus strategies designed to ensure that the information states of all vehicles in a network converge to a common value. This approach strengthens the team, minimizing power consumption and the effects of range and other restrictions.The monograph covers introductory, theoretical and experimental material, featuring - an overview of the use of consensus algorithms in cooperative control; - consensus algorithms in single- and double-integrator, and rigid-body-attitude dynamics; - rendezvous and axial alignment, formation control, deep-space formation flying, fire monitoring and surveillance.Six appendices cover material drawn from graph, matrix, linear and nonlinear systems theories.

This book presents a systematic study of an emerging field in the development of multi-agent systems. In a wide spectrum of applications, it is now common to see that multiple agents work cooperatively to accomplish a complex task. The book assists the implementation of such applications by promoting the ability of multi-agent systems to track — using local communication only — the mean value of signals of interest, even when these change rapidly with time and when no individual agent has direct access to the average signal across the whole team; for example, when a better estimation/control performance of multi-robot systems has to be guaranteed, it is desirable for each robot to compute or track the averaged changing measurements of all the robots at any time by communicating with only local neighboring robots. The book covers three factors in successful distributed average tracking:algorithm design via nonsmooth and extended PI control;distributed average tracking for double-integrator, general-linear, Euler–Lagrange, and input-saturated dynamics; andapplications in dynamic region-following formation control and distributed convex optimization. The book presents both the theory and applications in a general but self-contained manner, making it easy to follow for newcomers to the topic. The content presented fosters research advances in distributed average tracking and inspires future research directions in the field in academia and industry.

Pragmatic competence plays a key role in intercultural communication, particularly for students studying in a target community. This book investigates the effect of study abroad on second language learners’ productive and receptive pragmatic competences, as well as their cognitive processes during speech act production. It employs a variety of research instruments, both quantitative and qualitative, to explore learners’ pragmatic development over one year. The inclusion of a control group is a methodological strength of the longitudinal study, many such studies often not including a control group. In addition, the study longitudinally examines learners’ cognitive processes during study abroad with innovative and insightful analyses. The book makes an important contribution to second language pragmatics with regard to developmental changes in both speech act production and perception during such processes.

This book tells the story of the Mount Songshan area architecture in simple terms, while also providing detailed information on the history of Buddhist architecture. The history of the Mount Songshan area can be traced back to the Xia Dynasty in the 23rd century B.C. The heritage architecture in this area has seen the rise and fall of various powers – including the Han Dynasty, Northern Wei Dynasty, Tang and Song Empires, Jin Dynasty, Yuan Dynasty, and the Ming and Qing Empires – and reflects the character of each historical period. Over the past 2,000 years, history has been continuously woven into the architecture. The Mount Songshan area is, therefore, a perfect representation of the perpetual Chinese civilization, and the most magnificent museum of ancient Chinese architecture. Most importantly, these various types of architecture offer valuable insights into the architectural design and technologies of each historical period. The products of ingenuity and innovation, they are marvellous creations that ancient Chinese people took great pride in.
