Radical Solutions for Education in a Crisis Context: COVID-19 as an Opportunity for Global Learning (Lecture Notes in Educational Technology)
by Anita Tabacco Daniel Burgos Ahmed TliliThis book presents how to keep working on education in contexts of crisis, such as emergencies, zones of conflict, wars and health pandemics such as COVID-19. Specifically, this work shows a number of strategies to support global learning and teaching in online settings. Particularly, it first presents how to facilitate knowledge sharing and raising awareness about a specific crisis, to increase people’s safety, including educators and learners. The book then discusses various techniques, mechanisms and services that could be implemented to provide effective learning support for learners, especially in learning environments that they do not daily use, such as physical classrooms. Further, the work presents how to teach and support online educators, no matter if they are school teachers, university lecturers, youth social workers, vocational training facilitators or of any other kind. Finally, it describes worldwide case studies that have applied practical steps to keep education running during a crisis.This book provides readers with insights and guidelines on how to maintain learning undisrupted during contexts of crisis. It also provides basic and practical recommendations to the various stakeholders in educational contexts (students, content providers, technology services, policy makers, school teachers, university lecturers, academic managers, and others) about flexible, personalised and effective education in the context of crisis.

Radical by Nature: The Revolutionary Life of Alfred Russel Wallace
by James T. CostaA major biography of the brilliant naturalist, traveler, humanitarian, and codiscoverer of natural selectionAlfred Russel Wallace (1823–1913) was perhaps the most famed naturalist of the Victorian age. His expeditions to remote Amazonia and southeast Asia were the stuff of legend. A collector of thousands of species new to science, he shared in the discovery of natural selection and founded the discipline of evolutionary biogeography.Radical by Nature tells the story of Wallace&’s epic life and achievements, from his stellar rise from humble origins to his complicated friendship with Charles Darwin and other leading scientific lights of Britain to his devotion to social causes and movements that threatened to alienate him from scientific society.James Costa draws on letters, notebooks, and journals to provide a multifaceted account of a revolutionary life in science as well as Wallace&’s family life. He shows how the self-taught Wallace doggedly pursued bold, even radical ideas that caused a seismic shift in the natural sciences, and how he also courted controversy with nonscientific pursuits such as spiritualism and socialism. Costa describes Wallace&’s courageous social advocacy of women&’s rights, labor reform, and other important issues. He also sheds light on Wallace&’s complex relationship with Darwin, describing how Wallace graciously applauded his friend and rival, becoming one of his most ardent defenders.Weaving a revelatory narrative with the latest scholarship, Radical by Nature paints a mesmerizing portrait of a multifaceted thinker driven by a singular passion for science, a commitment to social justice, and a lifelong sense of wonder.

Radio Astronomy in Canada: Young Science in a Young Country (Historical & Cultural Astronomy)
by Elizabeth Griffin Richard Jarrell Jasper WallHere is the tale of Canada’s intriguing development of the science of Radio Astronomy. In 1946 the lone figure of Arthur Covington started monitoring the radio emission of the Sun, a programme that continues to this day. By the 1960s Canada had progressed to constructing two radio observatories at either ends of the country (the DRAO and the ARO), and universities were coming onboard. The story continues through the dire times for these and follows their fortunes and fates right up to the present, with Canada now playing key roles in billion-dollar international telescope projects. It concludes with the construction and operation of Canada’s own transformational telescope, CHIME. Anecdotes and images throughout the book liven the story.The authors—two practising astronomers—have painstakingly put together this fascinating story, drawing on first-hand experiences, valuable contributions from many colleagues, and the research of science historian, Richard Jarrell (1942-2013).This book fills a gap in the substantial literature on the history of radio astronomy. Carefully-researched by three experts and based on input by further experts in the field, it documents the extensive scientific and (especially) technical innovations of Canadian scientists and engineers. This includes the important Canadian absolute flux-density calibrations, the critical Canadian contribution to low-frequency radio astronomy and VLBI, and the long-running solar monitoring programme. Frank discussions about the excellent 46-m ARO telescope and its fate lead into considerations of Canada’s contributions to recent international projects – the JCMT, ALMA and the upcoming SKA. The book concludes with a description of CHIME, Canada’s own new-generation radio installation.Ken Kellermann, Senior Scientist Emeritus, National Radio Astronomy Observatory, Charlottesville, USA

Radio Engineering: From Software Radio to Cognitive Radio (Lecture Notes Of The Institute For Computer Sciences, Social Informatics And Telecommunications Engineering Ser. #172)
by Jacques Palicot Pierre‐Noël FavennecSoftware radio ideally provides the opportunity to communicate with any radio communication standard by modifying only the software, without any modification to hardware components. However, taking into account the static behavior of current communications protocols, the spectrum efficiency optimization, and flexibility, the radio domain has become an important factor. From this thinking appeared the cognitive radio paradigm. This evolution is today inescapable in the modern radio communication world. It provides an autonomous behavior to the equipment and therefore the adaptation of communication parameters to better match their needs. This collective work provides engineers, researchers and radio designers with the necessary information from mathematical analysis and hardware architectures to design methodology and tools, running platforms and standardization in order to understand this new cognitive radio domain.

Radio Frequency Identification Technologies: A Workshop Summary
by Committee on Radio Frequency Identification TechnologiesRadio Frequency Identification (RFID) technology is gaining rapid acceptance as a means to track a wide array of manufactured objects. Currently, RFID technologies have shown promise in transportation (e.g., smart fare cards) and commerce (e.g., inventory control) for a variety of uses and are likely to find many new applications in both military and civilian areas if and when current technical issues are resolved. There are a number of policy concerns (e.g., privacy), however, that will become more crucial as the technology spreads. This report presents a summary of a workshop, held by the NRC at the request of the Defense Advanced Research Projects Agency, to explore many of the key technical and policy issues. Several important themes that are likely to govern expansion of RFID technology emerged from the workshop and are discussed.

The RFID advantages are discussed, along with its numerous features, and comparisons with the barcode technology are presented. After that, the new chipless RFID technology is introduced on the basis of the previous conclusions. Original technological approaches are introduced and discussed in order to demonstrate the practical and economic potential of the chipless technology.
