Radio Communications

In the last decades the restless evolution of information and communication technologies (ICT) brought to a deep transformation of our habits. The growth of the Internet and the advances in hardware and software implementations modified our way to communicate and to share information. In this book, an overview of the major issues faced today by researchers in the field of radio communications is given through 35 high quality chapters written by specialists working in universities and research centers all over the world. Various aspects will be deeply discussed: channel modeling, beamforming, multiple antennas, cooperative networks, opportunistic scheduling, advanced admission control, handover management, systems performance assessment, routing issues in mobility conditions, localization, web security. Advanced techniques for the radio resource management will be discussed both in single and multiple radio technologies; either in infrastructure, mesh or ad hoc networks

Advanced Trends in Wireless Communications

Physical limitations on wireless communication channels impose huge challenges to reliable communication. Bandwidth limitations, propagation loss, noise and interference make the wireless channel a narrow pipe that does not readily accommodate rapid flow of data. Thus, researches aim to design systems that are suitable to operate in such channels, in order to have high performance quality of service. Also, the mobility of the communication systems requires further investigations to reduce the complexity and the power consumption of the receiver. This book aims to provide highlights of the current research in the field of wireless communications. The subjects discussed are very valuable to communication researchers rather than researchers in the wireless related areas. The book chapters cover a wide range of wireless communication topics

Urban Informatics

This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity

Perfect moments: British advertising during the 1990s - an assessment of determinants

The aim of this thesis is to consider how advertisers and their clients in the 1990s conceptualised social and technological change. In particular, I address how advertisers deduced and represented new characteristics in their customers. By reflecting on changes in the content of adverts, I take a symptomatic approach in considering how new conceptualisations were incorporated into new and broader ad styles. To do this, in Chapter 1, the Literature Review, I identify my central approach and key issues against existing literature in the field. Given that this study is essentially an industry-oriented analysis of advertising, which not been attempted this way before, I consider the relevance of existing industrial and academic-centred critical models for this study. Chapter 2 then maps out the key changes in advertising in the 1990s from previous decades. It considers what prompted the ad industries to change their perspectives and how advertisers restructured their operations in an attempt to re-imagine their consumers. In Chapter 3 benchmarks of the key changes are examined in more detail. Three campaigns are examined to explore how promotional strategies negotiated (perceived) changes in consumers. The campaigns for Britvic Tango (1992), Daewoo cars (1995) and Tesco Clubcard (1997) were chosen because they are symptomatic of key moments during the 1990s in which the way advertising targeted consumers was re-addressed. In the final part of this chapter I consider how shifting methods of advertising during the 1990s registers in the 'bigger picture' of twentieth century communication. Following the case studies, the next two chapters review two key issues for advertising during the 1990s. Chapter 4 considers how advertisers changed their tone of address. Here issues such as national/personal representation and 'boutiques of history' are considered. Most notably, changes in youth mood is considered against advertising's own strategies for coping with change. Chapter 5 then considers changes in modes of address, and in particular the impact of digital technology on advertising's means of communication. Unlike the previous chapter, which demonstrates how advertising negotiated change, this section shows how the existing agency system was forced to change. Before 1990 an attitude perSisted in the ad industry that changes to the way agencies communicated and did business was (to a large extent) determined by advertisers themselves. This was not the case in 1990s. This study maps out how change was negotiated in a climate of cultural fragmentation and digitised communication
