Reflecting a growing interest in phased array antenna systems, stemming from radar, radio astronomy, mobile communications and satellite broadcasting, Array and Phased Array Antenna Basics introduces the principles of array and phased array antennas. Packed with first-hand practical experience and worked-out examples, this is a valuable learning tool and reference source for those wishing to improve their understanding of basic array antenna systems without relying heavily on a thorough knowledge of electromagnetics or antenna theory. Features a general introduction to antennas and explains the array antenna principle through discussion of the physical characteristics rather than the theory Explores topics often not covered in antenna textbooks, such as active element pattern, array feeding, means of phase changing, array antenna characterisation, sequential rotation techniques and reactively loaded arrays Guides the reader through the necessary mathematics, allowing them to move onto specialist books on array and phased array antennas with a greater understanding of the topic Supported by a companion website on which instructors and lecturers can find electronic versions of the figures An ideal introduction for those without a background in antennas, this clear, concise volume will appeal to technicians, researchers and managers working in academia, government, telecommunications and radio astronomy. It will also be a valuable resource for professionals and postgraduates with some antenna knowledge.

"This book is intended to serve two purposes: to provide a coherent explanation of the theories and procedures that underpin forensic radio surveying and of the network technologies being surveyed in a form that can be read cover to cover as a text book; but also to act as a reference resource that can be dipped into as needed"--
This book is intended to be used as both a text book and as an aide memoire handbook by forensic radio survey engineers, particularly those working for official police agencies.
Provides a unique focus on radio protocols for LTE and LTE-Advanced (LTE-A) Giving readers a valuable understanding of LTE radio protocols, this book covers LTE (Long-Term Evolution) Layer 2/3 radio protocols as well as new features including LTE-Advanced. It is divided into two sections to differentiate between the two technologies’ characteristics. The authors systematically explain the design principles and functions of LTE radio protocols during the development of mobile handsets. The book also provides essential knowledge on the interaction between mobile networks and mobile handsets. Among the first publications based on the 3GPP R10 specifications, which introduces LTE-A Beginning with an overview of LTE, topics covered include: Idle Mode Procedure; Packet Data Convergence Protocol and Public Warning Systems Presents the LTE radio interface protocol layers in a readable manner, to enhance the material in the standards publications From an expert author team who have been directly working on the 3GPP standards It is targeted at professionals working or intending to work in the area and can also serve as supplementary reading material for students who need to know how theory on the most extensively used mobile radio interface today is put into practice

This book is an accessible introduction to quantitative data analysis, concentrating on the key issues facing those new to research, such as how to decide which statistical procedure is suitable, and how to interpret the subsequent results.
"This thoroughly revised and updated classic once again presents aguide to understanding, designing and conducting a qualitativeresearch study. The fourth edition retains the reader-friendly, jargon-free style,making the book accessible to both novice and experiencedresearchers. While the book is practical guide to design andimplementation of a qualitative research study, it also helpsreaders understand the theoretical and philosophical underpinningsof this research paradigm. Drawing on the latest literature as well as both authors'experience with conducting and teaching qualitative research, thefourth edition includes new material on case study research andaction research; discussion of online data sources (video, email,skype); updated discussion of data analysis software packages anduses; new discussion of data analysis strategies, includingnarrative analysis and poetic analysis; and a section on multipleways of presenting qualitative research findings. References,examples, and quotes have all been updated throughout the book"--

News media strongly influence how we picture public affairs across the world, playing a significant and sometimes controversial role in determining which topics are at the centre of public attention and action. Setting the Agenda, first published in 2004, has become the go-to textbook on this crucial topic. In this timely third edition, Maxwell McCombs – a pioneer of agenda-setting research – and Sebastián Valenzuela – a senior scholar of agenda setting in Latin America – have expanded and updated the book for a new generation of students. In describing the media's influence on what we think about and how we think about it, Setting the Agenda also examines the sources of media agendas, the psychological explanation for their impact on the public agenda, and their consequences for attitudes, opinions and behaviours. New to this edition is a discussion of agenda setting in the widened media landscape, including a full chapter on network agenda setting and a lengthened presentation on agenda melding. The book also contains expanded material on social media and the role of agenda setting beyond the realm of public affairs, as well as a foreword from Donald L. Shaw and David H. Weaver, the co-founders of agenda-setting theory. This exciting new edition is an invaluable source for students of media, communications and politics, as well as those interested in the role of news in shaping and directing public opinion.

New to this edition is a discussion of agenda setting in the widened media landscape, including a full chapter on network agenda setting and a lengthened presentation on agenda melding.
Setting the Agenda describes the mass media’s significant and sometimes controversial role in determining which topics are at the centre of public attention and action. In this new edition of his comprehensive book, Max McCombs, one of the founding fathers of the agenda-setting tradition of research, extends his previous synthesis of hundreds of studies carried out on this central role of the mass media in the shaping of public opinion. Across the world, the mass media strongly influences how we picture public affairs. In describing this media influence on what we think about and how we think about it, Setting the Agenda also discusses the sources of these media agendas, the psychological explanation for their impact on the public agenda, and the subsequent consequences for attitudes, opinions and behaviour. New to this edition, McCombs debates the role of the expanded media landscape on agenda setting, the impact of the internet on the power of legacy media and the role of agenda setting beyond the realm of public affairs, This fully updated new edition will prove invaluable to students of media, communications and politics, as well as those interested in the role of mass media in shaping and directing public opinion.
