In the information age, telecommunications is the pillar of a strong economy. To developing countries, restructuring this industry is a necessary step toward integration into the world economy. Restructuring telecommunications, therefore, has been a pervasive issue in the economic reform programs of many countries in recent years. However, the nature of these changes has varied widely among these nations. "Unfinished Business" examines the process of reform in Mexico and contrasts it with that of the United States, Brazil, and New Zealand, examining both the economic and technological aspects of this highly complex situation.

Using interviews with key players in the policy process, Mariscal provides a detailed analysis of key elements and figures. Her multidisciplinary perspective allows for a full exploration of the international differences in telecommunications restructuring. Going beyond simply asking why privatization and deregulation policies were successfully implemented in Mexico, the work offers a comprehensive guide to the process and impact of policy choices on telecommunications development.

This monograph presents new theories and methods for fixed-time cooperative control of multi-agent systems. Fundamental concepts of fixed-time stability and stabilization are introduced with insightful understanding. This book presents solutions for several problems of fixed-time cooperative control using systematic design methods. The book compares fixed-time cooperative control with asymptotic cooperative control, demonstrating how the former can achieve better closed-loop performance and disturbance rejection properties. It also discusses the differences from finite-time control, and shows how fixed-time cooperative control can produce the faster rate of convergence and provide an explicit estimate of the settling time independent of initial conditions. This monograph presents multiple applications of fixed-time control schemes, including to distributed optimization of multi-agent systems, making it useful to students, researchers and engineers alike.

The proceedings includes a selection of papers covering a range of subjects focusing on topical areas of computer networks and security with a specific emphasis of novel environments, ranging from 5G and virtualised infrastructures to Internet of things, smart environments and cyber security issues. Networking represents the underlying core of current IT systems, providing the necessary communication support for complex infrastructures. Recent years have witnessed a number of novel concepts moving from theory to large scale implementations, such as Software Defined Networking, Network Function Virtualisation, 5G, smart environments, and IoT. These concepts change fundamentally the paradigms used in traditional networking, with a number of areas such as network routing and system or business security having to adjust or redesign to accommodate them. While the benefits are clear, through the advent of new applications, use cases, improved user interaction and experience, they also introduce new challenges for generic network architectures, mobility, security, traffic engineering.
