This textbook provides a rigorous mathematical perspective on error-correcting codes, starting with the basics and progressing through to the state-of-the-art. Algebraic, combinatorial, and geometric approaches to coding theory are adopted with the aim of highlighting how coding can have an important real-world impact. Because it carefully balances both theory and applications, this book will be an indispensable resource for readers seeking a timely treatment of error-correcting codes.Early chapters cover fundamental concepts, introducing Shannon¿s theorem, asymptotically good codes and linear codes. The book then goes on to cover other types of codes including chapters on cyclic codes, maximum distance separable codes, LDPC codes, p-adic codes, amongst others. Those undertaking independent study will appreciate the helpful exercises with selected solutions.A Course in Algebraic Error-Correcting Codes suits an interdisciplinary audience atthe Masters level, including students of mathematics, engineering, physics, and computer science. Advanced undergraduates will find this a useful resource as well. An understanding of linear algebra is assumed.

Invasive species, generally, affect economically important crops, thus affecting the livelihoods of millions of people along crop value chains. Typically, invasive species have high migratory capabilities and, because of plant material exchanges made during trade, they cannot be contained by one country. Usually, African countries react after a pest has invaded and established itself in the country, making the cost of mitigating the pest even more expensive. This book presents a pan-African view of the impacts of invasive insect pests on agriculture and of how invasive species impact on productivity in Africa. It not only describes their importance, but also presents a diversity of research findings in the field, ranging from the use of early warning and monitoring systems for quarantine purposes, agricultural extension, all the way to control strategies. The IPM arsenal presented in this book includes the use of botanical bioactive compounds, semiochemicals, resistant varieties, biological control agents such as entomopathogens, endophytes, predators, and natural enemies. Aspects of technology transfer strategies, regional coordination, and farmers¿ perceptions have not been overlooked, because these affect the adoption of mitigation strategies. The book also presents measures that would help agricultural research services to estimate the damage and take actions for preparedness and readiness to face invasive insect pests. This starts with a basic knowledge of taxonomy to enable concerned persons to describe the insects and the vast inventory of affected crops. Physiological and ecological aspects of invasive pests are strongly highlighted to strengthen Integrated Pest Management Strategies. The threat of invasive species will remain permanent; therefore, the book encourages knowledge exchange and collaboration between researchers and scientists on the continent, while encouraging the establishment of a platform or a fund for preparedness and rapid response.

The book analyzes the financialization of the Brazilian territory to identify its main actors, technical systems and processes. The work is divided into three parts, which correspond to the three main scales of analysis of the national financial system: 1. the global scale, which defines the relative position of Brazil in the international division of financial work, emphasizing the role of São Paulo as an international financial centre; 2 the national level, which demonstrates the recent development of the financial and banking system (after 1964), with emphasis on the location and regionalization of bank headquarters and branches, as well as the new electronic channels for the provision of banking services (ATMs, points-of-sales, mobile and Internet banking); and 3. the local scale, which shows how these new financial agents and technical systems affect the Brazilian urban population, emphasizing the indebtedness of the lower income classes,as well as the emergence of alternative ways of using finance, such as fintechs, credit cooperatives and community banks.

This book presents various aspects of salt and drought stress signaling in crops, combining physiological, biochemical, and molecular studies. Salt and drought stress are two major constraints on crop production worldwide. Plants possess several mechanisms to cope with the adverse effects of salt and drought. Among these mechanisms, stress signaling is very important, because it integrates and regulates nuclear gene expression and other cellular activities, which can help to restore cellular homeostasis. Accordingly, understanding the signaling cascades will help plant biologists to grasp the tolerance mechanisms that allow breeders to develop tolerant crop varieties. This book is an essential resource for researchers and graduate students working on salt and drought stress physiology and plant breeding.

This book brings together several aspects of hosting capacity (HC) assessment and enhancement of modern electrical power systems, HC is a key enabler for affordable, reliable and renewable energy sources, that will aid in transitioning away from traditional high-carbon energy sources. The chapters provide insight into the state of the art on current hosting capacity concepts, restrictive performance limits, distribution network operators and network planners¿ viewpoints, and the cutting-edge technologies deployed worldwide for hosting capacity enhancement. Written by leading experts in power, control, and renewable energy resources. This book is beneficial to distribution system operators, network planners, distribution generation investors, and researchers in this field. Due to its broad scope, it is an ideal resource for students in advanced graduate-level courses and special topics in the field of hosting capacity assessment and enhancement in modern electricalpower systems.
