Home-based rehabilitation is an essential step to maximize the recovery of patients during their rehabilitation programs. Experts, between scheduled sessions, recommend home-based rehabilitation exercises. However, there is a lack of motivation for patients to perform these repetitive tasks. Serious games have been used recently as a solution for this problem. These games also help improve the patient motivation problem, but most of them do not include cognitive aspects. In this paper, we propose a serious gaming system, for cognitive and functional rehabilitation, implemented using a system of systems approach. The overall system integrates inertial sensors and Kinect cameras to estimate the kinematic data of the patient, and a dance pad to interact with the game.

In this paper, a cooperative exploration strategy of an unknown environment using a team of Micro-Aerial Vehicle (MAV) with embedded vision is proposed. The key problem is to cooperatively choose specific regions of the environment to be simultaneously explored and mapped by each robot in an optimized manner, in order to reduce exploration time and energy consumption. Further, target goals are assigned to robots by considering a trade-off between fast exploration and getting detailed grid maps, thus the robots can be efficiently distributed over the environment. Hence, robots communication skills are essential and usually the robots exchange their reconstructed maps for decision making. However, in this paper, the novelty is to exchange map frontier points between robots instead of the whole grid map in order to save communication bandwidth. Our approach is implemented and tested under ROS using the GAZEBO environment for multi-MAV simulation. In addition, we use three MAVs to show that the proposed approach efficiently spreads the robots in a cooperatively way into the environment, and also minimizes the exploration time. Furthermore, we propose an evaluation of our system performance using an Ad Hoc network to point out the saved exchanged data size and the ability of the multi-MAV system to cope with real network issues.

The control and protection of a user data is a very important aspect in the design and deployment of the Internet of Things (IoT). In this paper we propose a security-based modelling language for IoT systems, which explicitly represents data access controls. The language leverages the analysis of potential security failures resulting from a series of interactions between heterogeneous components of a system. We implemented a tool that automatically transforms IoT models into BIP models, which can then be simulated and analyzed for security guarantees. We illustrate the features of our language with a use-case inspired by an industrial scenario.

Researchers in the field of underwater robotics have been looking at biomimicry to reduce the vehicles impact on the local environment. To do so, an analysis of the relationship between the surface velocity of a stingray inspired robot and the parameters of its waveform motion is required. By applying linear and polynomial regression to a series of trials that vary the waveform parameters, three numerical models were produced. These numerical models can be used to determine a baseline for the performance of a robotic stingray in autonomous and swarming applications.

A System-of-Systems (SoS) is architecturally designed to exhibit emergent behavior from the interaction of independent systems. Based on the supervenience principle, an emergent behavior is a macro-scale behavior upwardly caused by a set of micro-scale behaviors according to alternative approaches: (i) endogenous, when the micro-scale behaviors originate from inside constituent systems of the SoS; (ii) exogenous, when oppositely the micro-scale behaviors originate from outside constituent systems. This paper presents the concepts and constructs of a novel Architecture Description Language (ADL), named SosADL, for exogenously describing architectural emergent behaviors of software-intensive SoSs. In particular, it demonstrates how architectural mediators expressed with SosADL supports exogenous architecture descriptions through an excerpt of a real application for architecting a Reconnaissance SoS, focusing on the flocking behavior of a fleet of Unmanned Aerial Vehicles (UAVs).

The growing interest in the study of system of systems (SoS) is evident due to the increasing number of such systems especially in cities. Unfortunately, it is often challenging to articulate a SoS concept due to the multiple subsystems and numerous stakeholders and their interactions and the many possible unintended consequences of such a system. Without a proper front end or concept development, such a SoS is likely to face many more problems and challenges later on in engineering development and post development. Hence, knowing how to carry out concept development of a SoS is of great importance. This paper examines how concept development of a system of systems could be taught.

The transition from capabilities provided by traditional physical systems to today’s capabilities provided by heterogeneous systems of systems complicates architecting. In this paper, we look at trends in this ongoing transition, especially into the degree of heterogeneity of technologies and the context. We observe in an increase in virtual intangible technologies from the cyber domain, and an increase in human and organization aspects. Main question is how the heterogeneity of concerns, needs, considerations, and technologies impacts architecting and the role of architects.

The Internet of Things essentially refers to a distributed system consisting of interconnected objects and computing resources that provide services to human or other systems. Systems of this nature already are embedded in Systems of Systems (SoS) like smart factories and smart cities.

Chronic diseases are on the rise, increasing in number and complexity. Consequently, the needs of patients with chronic diseases are increasing and becoming more complex and multi-faceted; they require addressing not only the physical body, but also behavioral, emotional, and spiritual health. The current healthcare delivery system organically developed to address acute conditions, primarily injury and infection during the mid-19th century, a time when the body was viewed as a machine. This led to the organization of the healthcare delivery system by organ systems into specialties and departments. However, the healthcare delivery system today needs to provide healthcare services that span multiple systems to provide the care patients need. Such care requires services from multiple specialties (e.g., podiatry and endocrinology for diabetes, primary care and psychiatry for behavioral health, and palliative care MDs and chaplains & social workers for end-of-life care) that each effectively functions as its own system. There are currently several limitations and difficulties in designing patient-oriented healthcare services utilizing a system of systems framework. First, clinical models describe the service with a focus on resources. Second, the description tends to be at a high-level of abstraction, leaving the details to the implementer. Finally, the patient is generally modeled as an operand non-participatory agent, being pushed and pulled through the system. This paper describes the use of engineering and systems principles to design patient-oriented healthcare services that provide detail and quantification that classic services do not model. In doing so, these designed system of system models incorporate the detail, data quantification and implementation level information to allow for the success of the clinical aspect of the model to be achieved. This paper presents a medical based description of a system of systems and the engineered system based description of an integrated patient-oriented service.

An important element of Systems Engineering is the allocation of requirements to system components. This is currently not handled consistently by architectural and modelling methods. In this paper we review the current situation and identify part of the the problem as a difference in the treatment of requirements. We propose an outline approach to improving the situation based on treating functional requirements as “behaviours” modelled in a semi-formal way
