Manpower is driving up DoD costs while DoD budgets are shrinking; therefore the DoD customer seeks a solution to enable increased mission capacity along with staff reductions. One way to accomplish this is through an autonomous capability to support end-to-end mission activities. The Mission Information Autonomous Intelligent Decision Engine (MiAide) approach for meeting this objective is to create...
Design of a web-based thesaurus for Systems of Systems Engineering (SoSE) discipline is presented in this article. Due to lack of linguistic clarity within this emerging discipline, there is a strong need to represent and interpret SoS concepts and terms to align heterogeneous models, and tools and techniques developed for SoS operations, management and its governance. A Blackboard-based systems approach...
The Robotic Arm (RA) has operated for more than 200 Martian solar days (or sols) since the Mars Science Laboratory rover touched down in Gale Crater on August 5, 2012. During the first seven months on Mars the robotic arm has performed multiple contact science sols including the positioning of the Alpha Particle X-Ray Spectrometer (APXS) and/or Mars Hand Lens Imager (MAHLI) with respect to rocks or...
Cloud computing is evolving into the default operational framework running modern data centers. Efficient data center operation is concerned with the total amount of energy consumed as well as assuring adequate resources are available to process all of the incoming work requests. Existing research has demonstrated several algorithms that can be used to determine the optimal number of resources required...
This study has been studied SIRMs (Single Input Rule Modules) connected fuzzy inference model in order to provide the insight into fuzzy control systems. The framework consists of two propositions: To guarantee the convergence of optimal solution, a set of fuzzy membership functions (admissible fuzzy controller) which are selected out of continuous function space is compact metrizable. And assuming...
The Rover Sequencing and Visualization Program (RSVP) is a tool suite used for building command sequences for the Mars Science Laboratory rover Curiosity. RSVP was previously used for other missions and for in-house research projects and proposal efforts. RSVP has undergone extensive modifications and enhancements over previous versions in order to support more challenging requirements and to make...
In this paper a Relational Oriented Systems Engineering and Technology Tradeoff Analysis (ROSETTA) framework is introduced for performing technology tradeoff and design studies with respect to the live, virtual and constructive mixes for aircrew training. This novel, efficient and model driven repeatable approach to the present and future problem of live / synthetic mixes on-board a real aircraft...
Cloud computing services are being adopted to expand applications across dispersed data-center sites. As these new paradigms require active data exchange, they impose further virtual network (VN) mappings over operator networks. Now clearly, service recovery after large catastrophic events is a key concern for mission-critical cloud services. Hence in order to address this challenge, this paper presents...
Large data has been accumulating in all aspects of our lives for quite some time. Advances in sensor technology, the Internet, wireless communication, and inexpensive memory have all contributed to an explosion of “Big Data”. System of Systems (SoS) integrate independently operating, non-homogeneous systems to achieve a higher goal than the sum of the parts. Today's SoS are also contributing to the...
Societal and technological advancements along with lessons learned from previous projects and space programs resulted in the creation of the International Space Station (ISS). The ISS is an engineering marvel created by a collaboration of 16 International Partners (IP's), space agencies, contractors and sub-contractors whose primary purpose is to conduct research in space for benefit of mankind. However,...
The Mars Science Laboratory Robotic Arm (RA) is a key component for achieving the primary scientific goals of the mission. The RA supports sample acquisition by precisely positioning a scoop above loose regolith or accurately preloading a percussive drill on Martian rocks or rover-mounted organic check materials. It assists sample processing by orienting a sample processing unit called CHIMRA through...

In a system of systems context, a variety of applications are dependent on the knowledge of location and attitude of individual agents in order to collaborate. For example, a soldier on the battle field observing a potential target transmits this information to a base station which then is shared with an unmanned air vehicle for surveillance. Without precise knowledge of the soldier's position and...
Random walk (RW) routing for Wireless Sensor Networks (WSNs) has been proven to balance energy consumption for the whole sensors. Since Compressive sensing (CS) provides a novel idea that can reconstruct all raw data based on a small number of measurements, the energy consumption for data gathering in WSNs is reduced significantly. The combination between RW routing and CS can help efficiently save...
One of the actual problems in product lifecycle management (PLM) is consideration of requirements from various systems. While a PLM system is focused on object interactions within a product, engineering for a product system requires interaction with other systems. This experience motivates research in integration of System of Systems (SoS) and PLM methodologies. In order to do the next step to include...
