The Department of Defense (DoD) manages a large, complex system of systems that must operate together on the battlefield to deliver value. However, it is difficult to understand the network wide impacts of changes to the system of systems. The DoD has had difficulty managing this system of systems due to the scale and complexity of the network and traditional systems engineering tools do not provide...
Deep feature learning methods have been aggressively applied in the field of music tagging retrieval Genre categorization, mood classification, and chord detection are the most common tags from local spectral to temporal structure. Convolutional Neural networks (CNNs) using kernels extract the local features that are in different levels of hierarchy while Recurrent Neural Networks (RNNs) discover...
This paper examines the relationship between enterprise transformation competencies and systems engineering competencies. We analyze a systems engineering competency model with respect to enterprise transformation competencies to show that many systems engineering competencies provide a solid foundation for providing an organization with an organic capacity to successfully accomplish enterprise transformation...
The adoption of model based systems engineering takes models and puts them front and center to support all systems engineering activities. The majority of the models are static models describing some aspects concerning the structure of the system. This paper addresses the question of what makes a good model. The paper discusses modeling languages and how quality is defined and measured in software...
A consistent, cohesive, and predictive framework that harbors the ontology and taxonomy of systems and system of systems is described that exposes the true nature of emergence as resulting from interactions that change physical objects. It is shown that the part-whole relationship is represented through the language syntax and semantics of integration and interoperability for systems and system of...
Quadcopters make up the bulk of research in unmanned aerial vehicles (UAVs). The lack of a fully open source quadcopter restricts the reproducibility and collaboration of practical research within the UAV community. This work focuses on creating a prototype quadcopter built upon hardware and software readily available and open sourced which can be extended and modified to place on any other quadcopter...
Marine robotics is a rapidly growing field, with applications of both Autonomous Underwater Vehicles (AUV) and Autonomous Surface Vehicles (ASV) becoming extensive and within reach for many people. Presented is a low-cost design for an ASV, focusing on the ability for the average person with only little mechanical and electrical skills to assemble. The ASV also incorporates a winch into its design,...
This paper presents a cyber energy system design for electric vehicle applications. The aim is to show more autonomy with superior efficiency of electric vehicles. In this paper, we have used four main energy sources: battery, super capacitor, fuel cell and solar panel. Moreover, we use in this architecture a low voltage 12V battery to supply the accessories in the vehicle. This battery can be recharged...
A System-of-Systems (SoS) is an integration of a finite number of Constituent Systems (CSs), which are networked together for achieving a certain higher goal. Therefore, integration is the key viability of any SoS. Although the integration of CSs can be achieved by the exchange of information, no existing work has considered the quality of such information. Without considering Information Quality...
A Missile Defense System (MDS), outside of a specific application within a single country of manufacture, is architecturally a system-of-systems (SoS). It is a coupling (sometimes tight or loose depending on configuration) of independently managed components, subsystems, and discrete systems that must work together in difficult environments against capable threats. We define a Multinational Missile...
During the last decade the integration of smart devices into humans' lives has witnessed an exponential increase. This has led to a new paradigm namely Cyber-Physical-Social Systems (CPSS) which consists of cyber components (computer systems) physical components (controlled objects) and social components (humans and their interactions). Although social components are playing a main role in CPSS their...
A System-of-Systems (SoS) is evolutionary developed from independent systems to achieve missions not possible to be accomplished by a single system alone. They are architecturally designed to exhibit emergent behavior, i.e. a new behavior that stem from the interactions among constituent systems, but cannot be deduced from the behaviors of the constituent systems themselves. This paper presents the...
Vanilla is among the most expensive and most produced spices in the world today. Hand pollination is required in most areas around the globe. Because of the amount of manual labour required for hand pollination automation should reduce the production cost and bring more organic vanilla to the spice market displacing adulterated products. A vanilla crane system for pollination was proposed and simulated...
As system of systems (SoS) models become increasingly complex and interconnected a new approach is needed to capture the effects of humans within the SoS. Many real-life events have shown the detrimental outcomes of failing to account for humans in the loop. This research introduces a novel and cross-disciplinary methodology for modeling humans interacting with technologies to perform tasks within...
Although high oil prices have attributed bad habits in a matter of “doing things right” rather than “doing the right things” in subsea productions, a continuous price drop renewed the need for cost cutting in recent years. This has been the case for subsea companies, where previous research found significant cost and schedule overruns due to late design changes. A large amount of these late design...
Engineering a system with the explicit goal of steering its emergent behavior is a relatively new human endeavor, and demands new ways of thinking about how we model system of systems (SoS) behavior. This paper discusses the definition of a system with an eye towards steering its emergent behaviors, frames negative emergent behaviors as those to be suppressed by engineering design, suggests that human...
Ideally, government policy is intended to improve economic, environmental, or social sustainability outcomes. Effective policy must address the ways that individual citizens, industries, and other government agencies will respond, and they must consider the implications on market systems, social systems, and ecosystems. This paper describes a system of systems approach to modeling and analyzing policy...
