This book contains the description of the research work done in COST Action 290 ‘Traffic and QoS Management in Wireless Multimedia Networks” which ran from March 2004 to June 2008. 24 European countries contributed to the research, with more than 70 institutions involved. The authors address new techniques and approaches to deal with the growth of data traffic in wireless mobile networks and the important need to guarantee differentiated quality of service levels to different traffic classes. The material presents the latest research achievements and rseults in research areas such as traffic engineering, mobility and interoperability, network architectures and planning as well as services, regulations, and economic aspects. This book covers broad areas of research onw ireless communications and networking from the physical layer through the application layer. It is recommended for resarchers and PhD students to receive a comprehensive and up-to-date overview on enigineering approaches, opimization methods and open issues in wireless multimedia networks.

The explosive growth of data, particularly internet traffic, has led to a dramatic increase in demand for transmission bandwidth, imposing an immmediate requirement for a broadband networks. The primary objective of the COST Action 291 ‘Towards Digital Optical Networks’ was to focus on novel network concepts, subsystems and architectures to enable future telecommunication networks, exploiting the features and properties of photonic technologies. Three working groups were established to deal with these research objectives:
WG1, Optical Processing for Digital Network Performance, dealt with the physical layer and implementation-related issues of transparent optical networks such as optical-signal-per-bit processing, optical-switch-architecture designs and implementations as well as transmissino-related issues.
WG2, Novel Network Architectures, focused on the evolution of network scenarios, including novel network architectures. Also different node architectures and technologies in terms of network performance and functionality were investigated. Three different architectures were studied and compared: circuit (wavelength, waveband, etc.), and optical-burst and optical-packet switched networks.
WG3, Unified Control Plane, Network Resilience and Service Security, dealt with the impact of transparency on photonic network architectures and the associated control and protocol issues as well as on network survivability and security issues, covering topics such as protection and restoration, routing and wavelength assignment algorithms, fault isolation, disaster recovery, etc.
The results obtained within these working groups are collected in this volume.

This volume brings together the selected and peer-reviewed contributions of the participants at the COST 2102 International Conference on Verbal and Nonverbal Features of Human-Human and Human-Machine Interaction, held in Patras, Greece.
The main theme of the conference was to foster existing and growing connections between the emerging field of technology devoted to the identification of individuals using biological traits and the fundamentals of verbal and nonverbal communication which include facial expressions, tones of voice, gestures, eye contact, spatial arrangements, patters of touch, expressive movement, cultural differences, and other “nonverbal” acts.
This book is broadly dividied into two scientific areas according to a thematic classification, even though all the areas are closely connected and all provdie fundamental insights for cross-fertilization of different disciplines.
