To develop an autonomous ship, the first step is to develop a system that shore crew are cooperating with navigator on board and maneuvering a ship. As the system uses satellite communication, there is a delay from the navigator command until the steering angle actually changes. In order to estimate the standard limit for the delay, this study investigated the navigator mental workload fluctuation in evading navigation with the steering system, which experiences delays caused by satellite communication. The experiment revealed that the navigator felt stress for a steering system delay of 2 s or more in evading navigation.

The future cyber physical systems consist of voltage regulators distributed across wide geographical areas. In this paper, a smart control approach of voltage regulators is presented for cyber physical system applications. The approach is implemented using K-means clustering algorithms that use data from voltage and current sensors, compute the correlation of changes across the regulators and generate a proportional feedback. Advanced estimation methods are used in cases where the data from the sensors was not available. The results show that the approach could be used to improve the performance of networked, power dependent systems by 94.5% in terms of overshoot and 9.52% in terms of response time as compared to other methods of controlling voltage regulators.

A major responsibility of architecting and integration is ensuring that desired dynamic behavior and desired qualities emerge from the interaction of components within the systems, between systems, and between the users and environment of the systems. A challenge is that organizational attention tends to be on the parts structure, which is determining organization, logistics, manufacturing, and servicing. At the same time, many developers lack the competence to capture dynamic behavior and the way qualities emerge. This paper explores the role of Systems of Systems (SoS) architecting in relation to the impact on integration and looks at alternative ways to visualize dynamic behavior. Three different Systems of Systems, both Directed and Acknowledged SoS, are studied. The visualizations in this paper aid in conceptualizing the system of interest to a larger stakeholder community. Visualizing dynamic behavior allows us to think and reason about potential changes and improvements of Systems of Systems. We encourage use of visualizing dynamic behavior from early conceptual phase and recommend that the developed visualizations are maintained and in active use throughout the SoS life cycle.

Driving automation is probably the most trending research topic at the current time, with huge investments from governments, research centers, and private companies. The majority of the current research and development in this area is focused towards autonomous driving capabilities in a mixed environment. Having a reference model of what land transportation would look like once fully automated is challenging due to the complexity of such system, but important nonetheless for any planning activities in order to avoid wasting time and effort, and to accelerate the transition towards a fully autonomous transportation SoS. In this paper, we model land transportation SoS, propose an internet-inspired reference model for autonomous driving, and a roadmap for accelerating its development.

As engineered systems increase their complexities, a new engineering nature of Systems of System (SoS) vitality is proposed aiming for a development trend from systems to self-adaption and self-recovery Cyber-physical Systems (CPS) in its adaptability to dynamic environmental changes. In terms of engineered system formalisms, an inorganic engineered system is transformed into a SoS composition with the characteristics of an organic lifeform, becoming a self-adaptive agent. Regarding to a way for constructing an engineering SoS, a traditional engineered system process model emerges in a new challenge with the addition of a virtual system in cyber space. In this paper, by analogy with the organic characteristics of living systems in nature, SoS vitality theory is proposed, which includes a technical framework and maturity level model for measuring the organic characteristics of engineering SoS for current technological development. This provides a conceptual reference for future directions in the development of engineered systems.

Faster development cycles of innovative products in business networks of mechanical engineering or smart home robotics companies challenge systems engineers responsible for Requirements Management and Engineering. Applying System of Systems aspects in organizing the R&D processes in a business network is the first step, to deal with these challenges. However, in order to link different Requirements Engineering methods, handle diverse product conformity documents and provide up to date product models for all network partners, a basic, common concept for Requirements Engineering and Requirements Management is needed. This concept should be flexible and adaptable for the specific needs of one partner, but also include some level of standardization. The following paper presents an innovative concept that can help to implement a structured procedure in business networks regarding Requirements Engineering and Requirements Management. Based on international literature analysis and an industry survey in Germany, the resulting, innovative concept - the ReMaiN-concept - is in the process of evaluation in German mechanical engineering and smart home robotics business networks right now.

The growing interest in System-of-Systems has resulted in rapid and widespread application of its concepts to a variety of problems. While this generated a large number of novel and valuable techniques, tools, and methodologies in System-of-Systems Engineering, it also broadened the problem domains, and subsequently made it difficult to achieve a high degree of coordination and cohesion in the discipline. Previous attempts at creating a formal structure to System-of-Systems Engineering provided valuable support to practitioners, but have been sometimes disconnected from the current practical needs in the discipline, leaving behind some pain points that still need to be addressed. In this work, we propose a different perspective to deal with the pain points: based on our experience and on analysis of the current challenges of System-of-Systems Engineering, we identify potential research directions which are based on domain-agnostic methodology, but of interest to a variety of problems in System-of-Systems. This dual feature of the research directions is explored here to identify a connection between the necessity of establishing formal and generic procedures for System-of-Systems Engineering along with the usability and utility of practical tools and techniques for applied problems.

Autonomous Navigation has been a field of major attraction to a large number of robotics enthusiasts all around the globe. Smart walker, a robot designed for assisting patients under intensive care, requires this exceptional add-on in order to have a better sense of the surrounding, captured through the RGB and depth sensor available on board. This paper addresses the navigation and mapping problem through a graph-based SLAM technique knows as Real-Time Appearance-based Mapping (RTAB-Map), which uses an interesting approach to map an area with the help of loop closures, and provides a number of visual feature tracking methods that can be used to detect the loop closures. The software stack on the Smart Walker has been built around ROS (Robot Operating System), and the necessary sensor, odometry and transformation messages have been configured accordingly, based on the onboard sensors and actuators attached to the Smart Walker. This paper discusses the implementation of RTAB-Map algorithm on the Smart Walker and steps involved in collecting a custom dataset. The approach also involves comparing the performance of visual feature tracking methods available in RTAB-Map algorithm on a standard dataset and on the custom dataset, based on non-statistical aspects in order to implement the right set of features for indoor use of the Smart Walker.

This paper proposes a new approach to the control of switching voltage regulators (buck converters). The method is performed using a switching-based clustering algorithm. The implementations of competing approaches such as a fuzzy-logic controller, proportional integral derivative controller and a neural network based controller are presented in order to compare and evaluate the performance of the switching-based clustering algorithm. The results of the approach show that the proposed method could improve the stability and the performance of the buck converter system by 2.7% in terms of settling time and by 0.6% in terms of the overshoot value as compared to other control methods for buck converters.
