Proper design of printed circuit boards can make the difference between a product passing emissions requirements during the first cycle or not. Traditional EMC design practices have been simply rule-based, that is, a list of rules-of-thumb are presented to the board designers to implement. When a particular rule-of-thumb is difficult to implement, it is often ignored. After the product is built, it will often fail emission requirements and various time consuming and costly add-ons are then required. Proper EMC design does not require advanced degrees from universities, nor does it require strenuous mathematics. It does require a basic understanding of the underlying principles of the potential causes of EMC emissions. With this basic understanding, circuit board designers can make trade-off decisions during the design phase to ensure optimum EMC design. Consideration of these potential sources will allow the design to pass the emissions requirements the first time in the test laboratory. A number of other books have been published on EMC. Most are general books on EMC and do not focus on printed circuit board is intended to help EMC engineers and design design. This book engineers understand the potential sources of emissions and how to reduce, control, or eliminate these sources. This book is intended to be a 'hands-on' book, that is, designers should be able to apply the concepts in this book directly to their designs in the real-world.

Electric and Music Industries Ltd (EMI) first saw the light of day in the UK in 1931. In a visionary move for the gramophone age, it manufactured both hardware (recording and playback equipment) and software (the records and tapes its machines would play). For over half a century, EMI dominated both sectors, it's music division eventually becoming the most successful in the world with a roster that at various times included "The Beatles", Maria Callas, Frank Sinatra, Cliff Richard, Pink Floyd, "The Beach Boys", "Queen", Robbie Williams, "The Spice Girls", Kate Bush and Kylie Minogue. Then in the 1990s, things started to go wrong.This title explores and investigates EMI's extraordinary decline from the greatness over two decades of rejected takeovers, unsuccessful mergers, executive changes, profit warnings, artist and staff cuts, press criticism and never-ending speculation. It includes interviews with many key players including former EMI Group/EMI Music executives Sir Colin Southgate, Jim Fifield, Eric Nicoli, Tony Wadsworth, David Munns, Rupert Perry, Ray Cooper and Jon Webster. He has also interviewed many managers, music journalists, financial analysists and rival record company executives. The result is the definitive account of a major international company's travails. It is also an eye-opening expose of the speed at which the music industry has changed.
English for Academic Purposes in the EMI Context in Asia
This edited book focuses on English for Academic Purposes (EAP) within the English as a Medium of Instruction (EMI) context in Asia, with a specific emphasis on the impact of EAP at Xi'an Jiaotong-Liverpool University (XJTLU) in China. Celebrating over 15 years of EAP provision at the university, the authors showcase research and best practices in EAP across various academic disciplines and address the growing need for tailored EAP teaching resources in the EMI environment. The volume presents evidence of XJTLU’s dedication to pedagogical innovations and to the professional development of its teaching staff, and includes studies of EAP pedagogies at undergraduate, taught Master’s, and doctoral levels, with diverse instructional and innovative foci. This book will be of interest to teachers, researchers, postgraduate students, and university policy makers, as well as anyone with a background in English for Academic Purposes (EAP) or English as a foreign language (EFL) teaching.
Teacher Professional Development Programs in EMI Settings
This book showcases a range of professional development activities in English medium instruction (EMI) from diverse international contexts. While EMI offers many benefits, it also comes with challenges for both teachers and learners, especially in terms of language proficiency, teaching practices, and curriculum design. To address these challenges, professional development activities are essential for supporting teachers and learners in EMI contexts. The scope of the book includes topics such as teacher training, curriculum design, assessment, classroom practices, and policy implementation in a range of EMI settings, including higher education, schools, and vocational institutions. The book offers practical guidance and innovative approaches for practitioners that will enhance their teaching practices and support their learners. The book also provides new insights into the challenges and opportunities of EMI in different contexts and contributes to the development of new theoretical frameworks for understanding EMI. This book is intended for EMI teachers, teacher trainers, researchers, policymakers, and administrators at different levels of education.

This book focuses on the linguistic needs of university students enrolled in English Medium Instruction (EMI) programmes in which disciplinary subjects are taught in English, a practice that has significantly risen over the last 20 years. It includes seven online, self-study modules (Creating outlines, concept maps, writing definitions, writing summaries, reporting data, the language of presentations and writing abstracts) that were designed after conducting specific research into students’ needs in terms of academic genres and language functions. All these modules were piloted with students in different degree programmes. The piloting confirmed the suitability of the materials for EMI undergraduate and postgraduate learners and the benefits of following a genre-based approach in this specific context.
