R1,721 Discovery Miles 17 210 Ships in 12 - 19 working days

Transformation Optics-based Antennas is organized into two chapters that follow an introduction that presents the basic principles of the transformation optics concept. Two types of transformation are presented, coordinate transformation and space transformation. Implementations using metamaterials are also discussed. Chapter One focuses on coordinate transformation in the design of devices capable of modifying the electromagnetic appearance of a radiating source. Transformation of a directive radiation pattern into an isotropic one (and vice-versa) through space stretching and compression, respectively, and the possibility of creating multiple beams are also studied. Chapter Two deals with devices designed using space transformation concepts. Quasi-conformal transformation optics (QCTO) are applied for the design of lenses, either to compensate for the phase shift created by the conformation of an array of sources or to steer a beam to an off-normal direction.

R1,426 Discovery Miles 14 260 Ships in 12 - 19 working days

Mobile phones are widely viewed as the information and communication technology that holds the most promise for bridging global digital divides. Gendered Power and Mobile Technology uses empirical research to focus on changing intersections between technology, gender and other categories of social and cultural power difference (such as age, race, class, and ethnicity) in the use of mobile communication technologies. Asking how these intersections can inform development discourse, practice, and research, this volume seeks to rectify the lack of attention to the Global South, calling for more sensitivity to the contexts and consequences of mobile phone use. Indeed, drawing on case studies from Ecuador, Ghana, Kenya, Mexico, Peru, Tanzania, and Uganda, this book engages with the intersectionality paradigm to tease out the complexities of using mobile technologies for development purposes. Gendered Power and Mobile Technology will appeal to students and researchers interested in fields such as media studies, development studies, gender and technology, feminist technoscience, anthropology, and sociology.

R1,523 Discovery Miles 15 230 Ships in 9 - 17 working days

One of the most significant and obvious examples of how mobile communication influences our understanding of time and space is how we coordinate with one another. Mobile communication enables us to call specific individuals, not general places. Regardless of location, we are able to make contact with almost anyone, almost anywhere. This advancement has changed, and continues to change, human interaction. Now, instead of agreeing on a particular time well beforehand, we can iteratively work out the most convenient time and place to meet at the last possible moment--on the way to the meeting or once we arrive at the destination.In their early days, mobile devices were primarily used for various types of emergency situations and for work. In some cases, the device was an essential element in various business operations or used so that overseas workers could communicate with their families. The distance between a remote posting and the people back home was suddenly and dramatically reduced. People began to share these devices not necessarily out of economic issues, but also questions of family and interpersonal dynamics.The process of sharing decisions as to who is a legitimate partner makes the nature of relationships more explicit. By examining the economy of sharing, we not only see how sharing mobile phones restructures social space, but are also given insight into an individual's web of interactions. This cutting-edge book deals with modern ways of thinking about communication and human interaction; it will illuminate the ways in which mobile communication alters our experience with space and time.

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

By now, it is commonly accepted that investments in information and communication technologies (ICTs) can facilitate macroeconomic growth in developed countries. Research standards in ICT for development (ICT4D) are high, and it is a basic expectation that a theoretically sound conceptual investigation should yield actionable results. An additional expectation is that an on-the-ground study conducted in each setting should add to the common body of knowledge based on theory. In other words, one is expected to make a connection between the world of concepts and the world of reality. Middle-range theories and frameworks could help connect the case studies with grand theories, by helping to create a theoretically sound and practically applicable research architecture of ICT4D. This book demonstrates how creative use of various data analysis methods (e.g., data mining [DM], data envelopment analysis [DEA], and structural equation modeling [SEM]) and conceptual frameworks (e.g., neoclassical growth accounting, chaos and complexity theories) may be utilized for inductive and deductive purposes to develop and to test, in step-by-step fashion, theoretically sound frameworks for a large subset of ICT4D research questions. Specifically, this book showcases the utilization of DM, DEA, and SEM for the following purposes: Identification of the relevant context-specific constructs (inductive application) Identification of the relationships between the constructs (inductive application) Development of a framework incorporating the constructs and relationships discovered (inductive application) Testing of the constructed framework (deductive application) The book takes a multi-theoretical perspective to economic development research. It starts with an overview of ICT4D. Next it covers such frameworks and theories as neoclassical growth accounting and the theory of complementarity, complex systems and chaos theories, and the product life cycle (PLC) theory. There are also nontechnical overviews of the DM and data analytic methods that can be used in this research. Also presented is evidence that human capital and investment capital are complementary and are reliable sources of economic growth. The book concludes with methodological frameworks to guide investment decisions and the formulation of strategic policy.
