This book develops limit theorems for a natural class of long range random walks on finitely generated torsion free nilpotent groups. The limits in these limit theorems are Lévy processes on some simply connected nilpotent Lie groups. Both the limit Lévy process and the limit Lie group carrying this process are determined by and depend on the law of the original random walk. The book offers the first systematic study of such limit theorems involving stable-like random walks and stable limit Lévy processes in the context of (non-commutative) nilpotent groups.

This book introduces a real-time optimization (RTO) method based on the dynamic correlation integration (DCI) theory, which has the performances of modeling-free and self-adaptive model changes in real process. With this method, the implementation of RTO could be simplified in great deal comparing to traditional modeling way in many cases, and it especially benefits to the RTO of complex chemical reactions and the processes which are difficult to modeling. This book is applicable to real-time optimization theory researchers and practical application engineers for reference.

Underwater robots play a significant role in ocean exploration. This book provides full coverage of the theoretical and practical aspects of bionic gliding underwater robots, including system design, modeling control, and motion planning. To overcome the inherent shortcomings of traditional underwater robots that can simultaneously lack maneuverability and endurance, a new type of robot, the bionic gliding underwater robot, has attracted much attention from scientists and engineers. On the one hand, by imitating the appearance and swimming mechanisms of natural creatures, bionic gliding underwater robots achieve high maneuverability, swimming efficiency, and strong concealment. On the other hand, borrowing from the buoyancy adjustment systems of underwater gliders, bionic gliding underwater robots can obtain strong endurance, which is significant in practical applications. Taking gliding robotic dolphin and fish as examples, the designed prototypes and proposed methods are discussed, offering valuable insights into the development of next-generation underwater robots that are well suited for various oceanic applications. This book will be of great interest to students and professionals alike in the field of robotics or intelligent control. It will also be a great reference for engineers or technicians who deal with the development of underwater robots.

A pioneer of cloud computing and big data offers his vision of the future world taking shape around us. Jian Wang was the founder and architect of Alibaba's cloud and has been the driving force behind its technology innovations. He was also the founder of the City Brain initiative to develop a new digital infrastructure for sustainable cities. Being Online is his meditation on the moment we are in, as the digital era shifts to the internet era, spawning new innovations at a seemingly dizzying pace: cloud computing, 5G, artificial intelligence, big data, wearables, robots, virtual reality, the internet of things, blockchain, and more. For Wang, the invisible hand that connects them is being online. The conjunction of computing, data, and the internet has erased the difference between being online and off. When computing can be done in the cloud, it is on the road to becoming a utility. When data is connected, making it big, its usefulness multiplies exponentially in unforeseeable ways, as does its value. This moment will be as transformative for humanity as Henry Ford's production line. Data is changing the nature of business. Computing is reshaping the economy. The cloud will help us do things we could never do before, at scales that were previously impossible. It will reshape our vision of the world, as electrification once did and, more recently, the transition from analog to digital. While telling the story of Alibaba’s breakthroughs and the development of his own understanding of the internet, Jian Wang's visionary book lays out the implications of this shift and how to think about being online.

This book mainly investigates the precision predictions on the signal of new physics at the Large Hadron Collider (LHC) in the perturbative Quantum Chromodynamics (QCD) scheme. The potential of the LHC to discover the signal of dark matter associated production with a photon is studied after including next-to-leading order QCD corrections. The factorization and resummation of t-channel top quark transverse momentum distribution in the standard model at both the Tevatron and the LHC with soft-collinear effective theory are presented. The potential of the early LHC to discover the signal of monotops is discussed. These examples illustrate the method of searching for new physics beyond what is known today with high precision.

This book investigates the industrial agglomeration and dispersion within a country under trade liberalization and interregional integration by considering both economic forces and geographical elements. Chapter 1 gives a brief introduction about the background, research topics and organizations in this book. Chapter 2 provides a detailed explanation of Krugman’s new economic geography (NEG) model and reviews the subsequent refinements of the original model from mainly geographical viewpoints. Chapter 3 extends Krugman’s original model to a two-country and three-region case where the domestic regions are fully asymmetrical in terms of their sizes and accessibilities to global markets. To better explain the reality of developing countries, chapter 4 presents an analytical model which assumes that unskilled workers are employed in both traditional and manufacturing sectors. Chapter 5 empirically investigates the home market effect (HME) in terms of wages in the case of China by using panel data for the period 1980–2012. Chapter 6 gives a summary and implication about the findings and conclusions in this book.

This is the second edition of Melt Rheology and its Role in Plastics Processing, although the title has changed to reflect its broadened scope. Advances in the recent years in rheometer technology and polymer science have greatly enhanced the usefulness of rheology in the plastics industry. It is now possible to design polymers having specific molecular structures and to predict the flow properties of melts having those structures. In addition, rheological properties now provide more precise information about molecular structure.This book provides all the information that is needed for the intelligent application of rheology in the development of new polymers, the determination of molecular structure and the correlation of processability with laboratory test data. Theory and equations are limited to what is essential for the use of rheology in the characterization of polymers, the development of new plastics materials and the prediction of plastics processing behavior. The emphasis is on information that will be of direct use to practitioners. Extensive references are provided for those wishing to pursue certain issues in greater depth. While the primary audience is applied polymer scientists and plastics engineers, the book will also be of use to postgraduate students in polymer science and engineering and as a text for a graduate course.

This volume presents recent developments in the area of Lévy-type processes and more general stochastic processes that behave locally like a Lévy process. Although written in a survey style, quite a few results are extensions of known theorems, and others are completely new. The focus is on the symbol of a Lévy-type process: a non-random function which is a counterpart of the characteristic exponent of a Lévy process. The class of stochastic processes which can be associated with a symbol is characterized, various schemes constructing a stochastic process from a given symbol are discussed, and it is shown how one can use the symbol in order to describe the sample path properties of the underlying process. Lastly, the symbol is used to approximate and simulate Levy-type processes.This is the third volume in a subseries of the Lecture Notes in Mathematics called Lévy Matters. Each volume describes a number of important topics in the theory or applications of Lévy processes and pays tribute to the state of the art of this rapidly evolving subject with special emphasis on the non-Brownian world.
