This book introduces a control problem with unique finite/fixed-time stability considerations, namely time-synchronized stability, where at the same time, all the system state elements converge to the origin, and fixed-time-synchronized stability, where the upper bound of the synchronized settling time is invariant with any initial state. Accordingly, sufficient conditions for (fixed-) time-synchronized stability are presented. These stability formulations grant essentially advantageous performance when a control system (with diversified subsystems) is expected to accomplish multiple actions synchronously, e.g., grasping with a robotic hand, multi-agent simultaneous cooperation, etc. Further, the analytical solution of a (fixed) time-synchronized stable system is obtained and discussed. Applications to linear systems, disturbed nonlinear systems, and network systems are provided. In addition, comparisons with traditional fixed/finite-time sliding mode control are suitably detailed to showcase the full power of (fixed-) time-synchronized control. ![]() English | 2022 | ISBN: 1501519034 , 978-1501519031 | 344 pages | True PDF EPUB | 290.45 MB The book covers continuous, long and natural fiber thermoplastic composites.

The chapters are arranged in a logical manner and establishes connections between concepts. Undergraduate chemistry concepts are explained clearly: every equation in physical chemistry is derived and justified while every organic reaction has its reaction mechanism shown and explained, without assuming that readers have university-level background in the subject. The book also contains original Chemistry Olympiad sample problems that readers may use to test their knowledge.This is a first book of its kind, written by Nan Zhihan, International Chemistry Olympiad (IChO) gold medallist and winner of the International Union of Pure and Applied Chemistry (IUPAC) Prize for achieving the highest score in the experimental exam, and experienced Chemistry Olympiad trainer Dr Zhang Sheng, who has served as head mentor of Singapore IChO team for many years. It builds on the experience of both a participant and trainer to help any aspiring Chemistry Olympiad student understand the challenging concepts in chemistry. ![]() English | 2022 | ISBN: 0299335941 | 215 pages | True PDF | 16.78 MB Through family interviews, original photographs, and national records, Beatrice Loftus McKenzie traces the many lives of a resilient multigenerational family whose experiences parallel the complicated relationship between America and China in the twentieth century. In the early 1900s, Charles Wong moved from Guangdong Province to the United States and opened the Nan King Lo Restaurant in Beloit, Wisconsin. Soon after, his wife Yee Shee joined him to build the "Chop House" into a local institution and start a family. When the Great Depression hit, the Wongs shared what they had with their neighbors. In 1938, Charles's tragic murder left Yee Shee to raise their seven children-ages one through fourteen-on her own. Rather than return to family property in Hong Kong, she and her children stayed in Beloit, buoyed by the friendships they had forged during the worst parts of the 1930s. ![]() English | 2022 | ISBN: 0300259085 | 270 pages | True EPUB | 5.26 MB An informed argument for an economic policy based on bridges of preparation and adaptation rather than walls of protection and exclusion ![]() English | 2022 | ISBN: 8770226512 , 978-8770226516 | 148 pages | True PDF | 98.12 MB The Urban Forest in the Age of Urbanizationseeks to reflect on the connotation of urban forestry in line with related emergent holistic theories. Today, much of the planet is urbanized and planners debate "Planetary Urbanization," economists discuss "The Global City," ecologists describe the planet's biodiversity hotspots, and climate scientists warn of a "global" crisis. We might think, therefore, that focusing on forestation approaches at the urban and peri-urban "edge" are reductionist. However, if the city is everywhere, and everything is a city, if the urbanized world now is a chain of metropolitan areas connected by places and corridors of communication, then what is not urban? And above all, which forests are not urban forests? ![]() English | 2021 | ISBN: 1538154587 | 261 pages | True PDF EPUB | 7.39 MB In-text URLs can be accessed via the "Features" tab of the publisher's website. ![]() English | 2021 | ISBN: 9811236445 | 401 pages | True PDF EPUB | 7.71 MB We are at a critical point in human history and that of the planet. In this book, a world leader in agricultural research, Professor Sayed Azam-Ali, proposes a radical transformation of our agrifood system. He argues that agriculture must be understood as part of global biodiversity and that food systems have cultural, nutritional, and social values beyond market price alone. He describes the perilous risks of relying on just four staple crops for most of our food and the consequences of our current agrifood model on human and planetary health.In plain language for the wider public, students, researchers, and policy makers, Azam-Ali envisions the agrifood system as a global public good in which its practitioners include a new and different generation of farmers, its production systems link novel and traditional technologies, and its activities encompass landscapes, urban spaces, and controlled environments. The book concludes with a call to action in which diversification of species, systems, knowledge, cultures, and products all contribute to The Ninth Revolution that will transform food systems for good. ![]() English | 2022 | ISBN: 1646042492 | 111 pages | epub | 5.01 MB Discover how to use the Glycemic Index to manage diabetes, control blood sugar, and monitor glucose intake from food to take control of your health. ![]() English | 2021 | ISBN: 0262045923 | 323 pages | True PDF | 18.5 MB Psychotherapy across distance and time, from Freud's treatments by mail to crisis hotlines, radio call-ins, chatbots, and Zoom sessions.
