Dear Sirs, dear Madams,
Society is currently experiencing the increasing population of “things,” able to autonomously link with each other and enact complex strategies to achieve tasks. The emergence of the Semantic Web, the Internet-of-Things, Ambient Intelligence, and cyber-physical societies make it impossible to capture the intricacies of the future highly dynamic and turbulent networks of interrelated computer-based and hybrid components. As such, it is important that systems are designed to self-adapt to changes without diverging from their intended functions as prescribed in their specifications. The mission of the International Journal of Adaptive, Resilient and Autonomic Systems (IJARAS) is to offer awareness and visibility to novel techniques and methods to achieve self-adaptability and self-resilience when systems and organizations are deployed in environments where change is the rule rather than the exception. IJARAS is also a tool to enhance the awareness of the key role played by said techniques and methods: engineering self-adaptive and self-resilient systems and organizations is an urgent necessity to keep society resilient in the face of the technology that sustains it. The journal pursues its mission by addressing researchers, practitioners, engineers, educators, and professionals and by publishing novel results on each of the diverse components of such a complex and multi-disciplinary research problem.
We invite you to follow the example of many a renowned researcher and submit your papers to IJARAS by following the guidelines here: http://win.ua.ac.be/~vincenz/ijaras/

PAPER ONE
An Approach to Adaptive Dependability Assessment in Dynamic and Evolving Connected Systems
Felicita Di Giandomenico (Istituto di Scienza e Tecnologie dell’Informazione “Alessandro Faedo”, Consiglio Nazionale delle Ricerche, Pisa, Italy), Antonia Bertolino (Istituto di Scienza e Tecnologie dell’Informazione “Alessandro Faedo”, Consiglio Nazionale delle Ricerche, Pisa, Italy), Antonello Calabrò (Istituto di Scienza e Tecnologie dell’Informazione “Alessandro Faedo”, Consiglio Nazionale delle Ricerche, Pisa, Italy) and Nicola Nostro (Istituto di Scienza e Tecnologie dell’Informazione “Alessandro Faedo”, Consiglio Nazionale delle Ricerche, Pisa, Italy)
Complexity, heterogeneity, interdependency and, especially, evolution of system/services specifications, related operating environments and user needs, are more and more highly relevant characteristics of modern and future software applications. Taking advantage of the experience gained in the context of the European project Connect, which addresses the challenging and ambitious topic of eternally functioning distributed and heterogeneous systems, this paper presents a framework to analyse and assess dependability and performance properties in dynamic and evolving contexts. The goal is to develop an adaptive approach by coupling stochastic model-based analysis, performed at design time to support the definition and implementation of software products complying with their stated dependability and performance requirements, with run-time monitoring to re-calibrate and enhance the dependability and performance prediction along evolution. The proposed framework for adaptive assessment is described and illustrated through a case study. To simplify the description while making more concrete the approach under study, the authors adopted the setting and terminology of the Connect project.

PAPER TWO
Applying Probabilistic Adaptation to Improve the Efficiency of Intra-Query Load Balancing
Daniel M. Yellin (IBM Israel Software Lab, Jerusalem, Israel) and Jorge Buenabad-Chávez (Departmento de Computación, Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional, Mexico City, Mexico)
In the context of adaptive query processing (AQP), several techniques have been proposed for dynamically adapting/redistributing processor load assignments throughout a computation to take account of varying resource capabilities. The effectiveness of these techniques depends heavily on when and to what they adapt processor load assignments, particularly in the presence of varying load imbalance. Most existing approaches to this problem use heuristics based only upon the current machine load levels. The authors provide an algorithm, prAdapt that probabilistically predicts the future load on processors, based upon the recent history. It uses this prediction to evaluate the expected performance of different alternative solutions, taking into account the cost of the adaptation itself. If it finds a better solution than the current load distribution policy, it adapts to that distribution. Using a simulation based evaluation; they compare prAdapt to other approaches for AQP reported in the literature. The authors’ simulation results indicate that prAdapt often outperforms these other approaches.

PAPER THREE
Multichannel Modality in Displaying Information
Elisa Benetti (Research & Development Division, Lepida S.p.A., Bologna, Italy) and Gianluca Mazzini (Research & Development Division, Lepida S.p.A., Bologna, & University of Ferrara, Ferrara, Italy)
Computer science and telecommunications are increasingly important in society and this leads also public administrations to take advantage of ICT, in order to communicate with citizens in a more rapid and simpler way than the complex and paper-based bureaucracy of the past. While on the one hand the use of these technologies responds to the duty of any public institution to involve the largest number of addressees, on the other hand, society must also consider the limitations of these technologies. Firstly not everybody is so familiar in their use. Moreover, the digital administration thus becomes virtual, accessible only through technological devices and not present in a physical location, and is therefore essential to ensure full coverage of the territory, which is currently not always possible. The main novelty of this paper is the implementation of an automated system capable of adapting different types of government services to multiple communication media. The joint exploitation of multiple technologies allows to use the strengths of one of them when are found the limits of another, making this multichannel modality the solution to the requirement of ICT in public administration.

PAPER FOUR
A Fully Reconfigurable Approach to Emergency Management
Daniele Tarchi (Department of Electrical, Electronic and Information Engineering, University of Bologna, Bologna, Italy), Valeria Petrini (Department of Electrical, Electronic and Information Engineering, University of Bologna, Bologna, Italy) and Giovanni Emanuele Corazza (Department of Electrical, Electronic and Information Engineering, University of Bologna, Bologna, Italy)
Emergency management is one of the most important areas where technology innovation has direct impact on social well-being and sustainability. In the past few years, Information and Communication Technology (ICT) has proved to be instrumental to improve emergency management with particular focus on resilience, rapidity of response, adaptability to situations. To these ends, joint optimization of communication and computing is a promising cross-layer approach. Indeed, this paper is focused on the consideration of both cognitive and autonomic networking approaches when deploying an emergency management system. The cognitive approach was initially considered specifically for wireless communications, while the autonomic approach was initially introduced for managing complex computing systems; however, they share several similarities in dealing with fully reconfigurable systems. The future trend is to expand their influence toward the global optimization of the ICT infrastructure, as the authors show in this paper for the specific case of emergency management systems.

PAPER FIVE
Mobility Management in Publish/Subscribe Middleware
Fatma Abdennadher (ReDCAD Research Unit, National School of Engineers of Sfax, University of Sfax, Sfax, Tunisia) and Maher Ben Jemaa (ReDCAD Research Unit, National School of Engineers of Sfax, University of Sfax, Sfax, Tunisia)
In this research work, a survey on Mobility issues in Publish/Subscribe (P/S) Middleware and their applications was carried out. Publish/subscribe is appearing as a communication paradigm matching well with highly dynamic distributed applications characterized by reconfigurability, flexibility, and scalability. Nevertheless, very few efforts tackle dynamic modifications in the topology of the P/S distributed dispatching infrastructure despite such events represent a basic confrontation in mobile computing scenarios. In this paper, the authors clarify the mobility’s issues in the context of publish-subscribe middleware and survey solutions and protocols suggested by several research groups.
