Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical haza...
The discovery of a traditional Welsh blanket in the palace of the former ruler of Yemen inspires this fascinating exploration of the link between Cardiff, once the world's biggest coal-exporting port, and Aden, where the coal that fueled the British Empire in Africa was bunkered. This narrative travels through mountain passes, deserts, ports, and the ancient cities of southern Arabia, encountering former seamen and remote communities in which stories of Cardiff loom large. As the journey progresses, this remarkable and timely account reveals the history of Yemen, a country at the center of Arab and world history, and the way in which two cultures touch each other.
Eco-Concepts: Critical Reflections in Emerging Ecocritical Theory and Ecological Thought offers an intellectual journey through the ever-evolving landscapes of environmental discourse. This thought-provoking volume brings together contributors from international scholarship to scrutinize and illuminate the contemporary trends reshaping our understanding of the natural environment. From the intricate interplay of rising ecocritical theories like restoration and empirical ecocriticism to the nuanced shifts in the reimagining of ecological concepts, this book unravels the complexities of our relationship with the natural sphere. This scholarly collection serves as a compass, guiding readers through the uncharted territories of environmental scholarship or revisiting existing study through fresh critical perspectives. Eco-Concepts strives to become an essential source of reference for academics, students, and individuals seeking an in-depth exploration of the innovative notions influencing the trajectory of discussions on ecology.
This book describes and provides design guidelines for antennas that achieve compactness by using the slot radiator as the fundamental building block within a periodic array, rather than a phased array. It provides the basic electromagnetic tools required to design and analyse these novel antennas, with sample calculations where relevant. The book presents a focused introduction and valuable insights into the relevant antenna technology, together with an overview of the main directions in the evolving technology of compact planar arrays. While the book discusses the historical evolution of compact array antennas, its main focus is on summarising the extensive body of literature on compact an...
The proceedings of the April 1994 Conference comprise 98 papers on topics in the following areas: general (subsections on finite elements--low frequency, and finite differences); modal and ray methods (subsection on finite element/boundary integral methods--low frequency); network methods and neural algorithm; CEM methods and applications; modeling high frequencies (subsections on transmission- line modeling, finite elements--high frequencies, boundary element--integral methods, and method of moments); and processing techniques.
