Peer-to-Peer Networking and Applications disseminates state-of-the-art research and development results to facilitate effective deployment of P2P networking and applications. The journal brings together and fosters interaction among academic and industrial communities to promote further research that leads to new P2P applications and services. This journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies and their impact on software engineering, computer engineering, networked communication, and security. It includes papers addressing system, application, and service issues. Peer-to-Peer Networking and Applications publishes original research papers, tutorials, reviews, case studies, and correspondences from the research, development, and standardization communities.

Personal and Ubiquitous Computing publishes peer-reviewed international research on handheld, wearable and mobile information devices and the pervasive communications infrastructure that supports them to enable the seamless integration of technology and people in their everyday lives. The journal carries compellingly-written, timely and accessible contributions that illuminate the technological, social and design challenges of personal and ubiquitous computing technologies. Personal and Ubiquitous Computing is an essential resource for researchers and educators who wish to understand the implications of ubiquitous computing.

Pervasive computing, often synonymously called ubiquitous computing, is an emerging field of research that brings in revolutionary paradigms for computing models in the 21st century. Tremendous developments in such technologies as wireless communications and networking, mobile computing and handheld devices, embedded systems, wearable computers, sensors, RFID tags, smart spaces, middleware, software agents, and the like, have led to the evolution of pervasive computing platforms as natural successor of mobile computing systems. The goal of pervasive computing is to create ambient intelligence where network devices embedded in the environment provide unobtrusive connectivity and services all the time, thus improving human experience and quality of life without explicit awareness of the underlying communications and computing technologies. In this environment, the world around us (e.g., key chains, coffee mugs, computers, appliances, cars, homes, offices, cities, and the human body) is interconnected as pervasive network of intelligent devices that cooperatively and autonomously collect, process and transport information, in order to adapt to the associated context and activity.The Pervasive and Mobile Computing Journal (PMC) is a professional, peer-reviewed journal that publishes high-quality scientific articles (both theory and practice) covering all aspects of pervasive computing and communications. Topics include, but not limited to:• Pervasive/Ubiquitous computing and communications architectures and protocols• Autonomic computing and communications• Mobile computing systems and services• Ambient, invisible, implicit, and adaptive computing• Mobile grid and peer-to-peer computing• Algorithmic paradigms, models and analysis of pervasive computing systems• Smart spaces and intelligent environments• Enabling technologies (e.g., Bluetooth, BANs, PANs, 802.11 wireless LANs)• Embedded systems and wearable computers• Wireless sensors networks and RFID technologies• Virtual immersion communications• Multiple inter-connected networking technologies (e.g., cellular, ad hoc, hybrid)• Positioning and tracking technologies• Auto-configuration and authentication• Context-aware computing and location-based services and applications• Service creation, discovery, management, and delivery mechanisms• Middleware and agent technologies• Application layer protocols and services• Programming paradigms for pervasive and ubiquitous computing applications• User interfaces and interaction models• Runtime support for intelligent, adaptive agents• (Innovative) applications requirements, performance, and benchmarking• Security, privacy, fault-tolerance and resiliency issues.

Problems of Information Transmission is an official journal of the Russian Academy of Sciences. This English translation of Problemy Peredachi Informatsii features articles of interest to investigators in all aspects of communication systems research and development. Readers will find coverage of statistical information theory; coding theory and techniques; noisy channels; error detection and correction; signal detection, extraction, and analysis; analysis of communication networks; optimal processing and routing; the theory of random processes; and bionics.

The journal publishes original research papers of high scientific level in the area of theoretical computer science and its applications. Theoretical computer science is understood in its broadest sense and comprises in particular the following areas: automata and formal languages, game theory, rewriting systems, design and analysis of algorithms, complexity theory, quantum computation, concurrent, distributed, parallel computations, verification of programs, “logic” and compilers, computational geometry and graphics on computers, cryptography, combinatorics on words.This list is not supposed to be exhaustive and the editorial board will promote new fields of research that will be worked out in the future.

The journal provides a focus for the dissemination of new results about the elicitation, representation and validation of requirements of software intensive information systems or applications. Theoretical and applied submissions are welcome, but all papers must explicitly address: the practical consequences of the ideas for the design of complex systems how the ideas should be evaluated by the reflective practitioner The journal is motivated by a multi-disciplinary view that considers requirements not only in terms of software components specification but also in terms of activities for their elicitation, representation and agreement, carried out within an organisational and social context. To this end, contributions are sought from fields such as software engineering, information systems, occupational sociology, cognitive and organisational psychology, human-computer interaction, computer-supported cooperative work, linguistics and philosophy for work addressing specifically requirements engineering iss
