Hardback. Condizione: New. The equipotential earth is a fundamental requirement of circuit theory, because it dramatically reduces the complexity of the mathematics required to simulate a circuit. Unfortunately, in the real world, no such equipotential earth exists, nor can it ever do so, which means simulating a circuit to evaluate its electromagnetic compatibility (EMC) and susceptibility to electromagnetic interference (EMI) is largely dependent on using the Maxwell equations. The Maxwell equations are inherently complex, however, and so have high processing power requirements and, as with all complex systems, there is a propensity to generate and magnify errors. Fortunately, the models provided in this book require far less processing power, as the mathematics required is far less complex than that of the Maxwell equations. These models are explained in a simple and straightforward manner, and can be used at the developmental stage of a project and redeployed in the testing stage before the manufacturing and product deployment stages are implemented. A review of the relationship of circuit theory with electromagnetic theory identifies a way of augmenting these analytical tools, and this enables circuit models to be developed to simulate all forms of EMI, thus effectively updating and extending circuit theory. The technique described in this book can be used to analyse all the mechanisms involved in the propagation of EMI. This approach avoids the need for endless debate on the topic of ground philosophy. Equally, it avoids the need to invoke the complexities of electromagnetic computation. The book is aimed at electrical and electronic design engineers and EMI/EMC design consultants.…

Paperback. Condizione: New. The Canadian Mountain Assessment provides a first-of-its-kind look at what we know, do not know, and need to know about mountain systems in Canada. The assessment is based on insights from First Nations, Métis, and Inuit knowledges of mountains, as well as findings from an extensive assessment of pertinent academic literature. Its inclusive knowledge co-creation approach brings these multiple forms of evidence together in ways that enhance our collective understanding of mountains in Canada, while also respecting and maintaining the integrity of different knowledge systems.The Canadian Mountain Assessment is a text-based document, but also includes a variety of visual materials as well as access to video recordings of oral knowledges shared by Indigenous individuals from mountain areas in Canada. The assessment is the result of over three years of work, during which time the initiative played an important role in connecting and cultivating relationships between mountain knowledge holders from across Canada. It is the outcome of contributions from more than 80 Indigenous and non-Indigenous individuals and contains six chapters:IntroductionMountain EnvironmentsMountains as HomelandsGifts of the MountainsMountains Under PressureDesirable Mountain FuturesBy way of these chapters, the Canadian Mountain Assessment aims to enhance appreciation for the diversity and significance of mountains in Canada, to clarify challenges and opportunities for mountain systems in the country, and to motivate and inform new research, relationships, and actions that support the realization of desirable mountain futures. More broadly, the Canadian Mountain Assessment provides insights into applied reconciliation efforts in a knowledge assessment context and seeks to inspire similar knowledge co-creation efforts in and beyond Canada.…
