An Introduction to MultiAgent Systems.

With digital equipment becoming increasingly networked, either on wired or wireless networks, for personal and professional use alike, distributed software systems have become a crucial element in information and communications technologies. The study of these systems forms the core of the ARLES' work, which is specifically concerned with defining new system software architectures, based on the use of emerging networking technologies. In this context, we concentrate on the study of distributed systems which bring to life the vision of ubiquitous computing systems, also known as ambient intelligence.

MES (multi-energy systems): An overview of concepts and evaluation models

Cyberphysical systems (CPSs) are new class of engineered systems that offer close interaction between cyber and physical components. The field of CPS has been identified as a key area of research, and CPSs are expected to play a major role in the design and development of future systems. In this paper, we survey recent advancements made in the development and applications of CPSs. We classify the existing research work based on their characteristics and identify the future challenges. We also discuss the examples of prototypes of CPSs. The aim of this survey is to enable researchers and system designers to get insights into the working and applications of CPSs and motivate them to propose novel solutions for making wide-scale adoption of CPS a tangible reality.

Design Techniques and Applications of Cyberphysical Systems: A Survey

Cyber-Physical Systems (CPSs) represent an emerging research area that has attracted the attention of many researchers. Starting from the definition of CPS, the paper discusses the need for these systems implementation in various application domains and the research challenges for defining an appropriate formalism that represent more than networking and information technology - the information and knowledge will be integrated into physical objects. As CPSs are expected to play a major role in the design and development of future engineering systems, a short state of the art regarding the main CPS research areas (generic architecture, design principles, modeling, dependability, and implementation) ends the paper.

Cyber-Physical Systems - Concept, Challenges and Research Areas

This paper presents definitions characterizing the concepts regarding cyber-physical systems and dependability. Cyber-physical systems incorporate computing, communication and storage capabilities with monitoring and/or control of entities in the physical world in a dependably, securely, efficiently and real-time way. The challenges of cyber-physical system research are concerning: real-time system abstractions; robustness, safety and security; QoS composition; and nor least dependability. Dependability is first introduced as a global concept that subsumes the usual attributes of reliability, availability, safety, integrity and maintainability. The paper aims to define research challenges to achieve the dependability in cyber-physical hydropower systems. The significant challenge of the dependability in cyber-physical hydropower systems is evaluation of the system behavior in terms of interdependencies between cyber and physical components of the system.

Unmanned aerial vehicles (UAVs) have gained special attention in recent years, among others in monitoring and inspection applications. In this paper, a less explored application field is proposed, railway inspection, where UAVs can be used to perform visual inspection tasks such as semaphore, catenary, or track inspection. We focus on lightweight UAVs, which can detect many events in railways (for example missing indicators or cabling, or obstacles on the tracks). An outdoor scenario is developed where a quadrotor visually detects a railway semaphore and flies around it autonomously, recording a video of it for offline post-processing. For these tasks, we exploit object detection methods from literature, and develop a visual servoing technique. Additionally, we perform a thorough comparison of several object detection approaches before selecting a preferred method. Then, we show the performance of the presented filtering solutions when they are used in servoing, and conclude our experiments with evaluating real outdoor flight trajectories using an AR.Drone 2.0 quadrotor.
