Fire Induced Flows, Smoke Transport and Coagulation: Numerical Simulations and Measurements
Application of the ‘large eddy simulation’ (LES) techniques to fires and fire induced flows and smoke transport is relatively recent. Though the demand on computational power is somewhat greater than the more traditional techniques of modeling fires, the application of LES techniques to modeling fire plumes and enclosure fires has resulted in remarkable extraction of temporal and spatial details. Large scale eddies are directly simulated and subgrid scale motion is represented with the Smagorinsky model. Several applications of the model of fire simulation will be presented. These include naturally occurring fire whirls; fire and smoke spread in aircraft cargo and passenger compartments and smoke transport and coagulation prediction.

The Challenges of System of Systems
A growing number of systems are routinely classified as systems of systems (SoS), even though clear and rigorous definitions are lacking, which differentiate SoS from other types of systems. SoS present many additional challenges than traditional systems. For example, the variety of systems, each with their own set of requirements, can cause problems for verification and validation, and the interconnected nature of these systems creates new complications for risk management. If indeed, there is something special about a SoS, then we need a way to uniquely separate such a system from other similar entities. We will discuss what makes a SoS different than a traditional system and explore some of its challenges.

Air Traffic Controller (ATC) Simulation with AGENTFLY
AGENTFLY is an agent-based, fast-time simulation model prototype in development by the Czech Technical University (CTU) for the FAA. The development of an ATC Agent within AGENTFLY was prompted by the need for human performance modeling to assess NextGen concepts in a fast-time simulation environment. This would not eliminate the need for real-time simulation, but would supplement a study by providing a first order look at human performance requirements and thus enhance the real-time simulation with output revealed during the fast-time simulations. AGENTFLY’s ATC agent is represented as a computer information-processing entity with four concurrent processing channels (Visual, Cognitive, Auditory, and Psychomotor, together abbreviated VCAP), in line with Wickens’ (1984) model of attention and mental workload. This presentation will cover the development of the ATC Agent as well as the AGENTFLY validation effort which showed positive results.

SPACE Weather
Understanding and predicting Space Weather has become important as society increasingly relies upon satellite technologies. The potential consequences of a solar storm could ripple through our technology and various infrastructures, causing economic and societal disruptions. Power grid outages, high-frequency communication blackouts, and spacecraft anomalies have all occurred in the past as a result of space weather. With the emergence of new industries such as Commercial space (space tourism) and Unmanned Airborne Systems (UAS), space weather presents new considerations. This presentation will introduce aspects of space weather and discuss some of the potential impacts from space weather events. Mr. Rosen is a navigation engineer for GDIT supporting FAA WJHTC Navigation Programs. He is versed in analysis of satellite navigation signals in space (GPS, WAAS). The study of ionospheric impacts on signals has included study of Space weather concepts. Mr. Rosen is a Lehigh University graduate in BS Computer Engineering and MS Electrical Engineering.

Well, you didn’t say not to! A formal systems engineering approach to teaching an unruly architecture good behavior
This presentation introduces a new formal modeling approach known as Monterey Phoenix (MP), which has features that enable prediction of emergent reactive system and system of systems (SoS) behaviors that result from interactions among subsystems and among the system and its environment. The approach emphasizes specification of component behavior and component interaction as separate concerns at the architectural level, consistent with well-accepted definitions of SoS. Implementing this separation of concerns in modeled architectures substantially increases the number of behaviors appearing in simulations for better prediction of design flaws and other latent behaviors. MP provides a new capability for automatically verifying system behaviors early in the lifecycle, when design flaws are most easily and inexpensively corrected. MP extends existing frameworks and allows multiple visualizations for different stakeholders, and has potential for application in multiple domains.

The Rise and Development of Synthesis Gas to Synthetic Fuels
High energy prices and volatility in recent years have stimulated worldwide interests in finding and developing new sources of energy to meet increasing demands. In the coming decades, coal, biomass and natural gas are expected to play a key role as alternative energy sources in the rapidly growing economy for countries like China, India as well as United States. To meet the needs of increasing supplies while protecting the environment, continued technology advances will be critical. One such development is the conversion of coal, biomass and natural gas into high quality, clean-burning transportation fuels. This presentation briefly introduces synthesis gas production via gasification of coal and biomass as well as via steam methane reforming of natural gas. The focus of the presentation will be in the liquid synthetic fuel production via synthesis gas.

Trajectory Based Operations Conflict Resolution Advisories
and
Determination of Lateral and Vertical Adherence to Route
Dr. Young’s paper describes a substantial fast-time simulation study that was conducted using the Conflict Resolution Advisory prototype software in an ERAM (En Route Automation Modernization)-like modeling environment. This study varied the extent to which 2-part amendments were fully entered into the ground automation, and calculated the effect on trajectory modeling and conflict probe alert performance. The paper describes the experiment and results in detail, and was awarded Best Paper of the session.
Ms. Nelson’s paper details determining the adherence of an aircraft to its cleared route of flight is critical in evaluating the performance of various NextGen components. The paper describes an algorithm used to calculate adherence, recent enhancements, and an experiment to calibrate and verify the modifications.

Managing Complexity in the 21st Century Enterprise
Dr. Felder will show that the application of digital processing to just about everything, including the smallest and most mundane appliances and subsystems, is a distinguishing feature of the information revolution. At the other end of the spectrum, digitally smart subcomponents are aggregated into systems, and those systems are in turn aggregated into widespread networks characterized by the constant and voluminous flow of data among component systems. These networked digital systems-of-systems, continuously evolving to new levels of complexity, require a transformed engineering approach. Looking at systems at an enterprise level leads to new approaches to the design, development, and management of the extended enterprise, including the application of architecture frameworks and portfolio management techniques. At the same time, the need for planning flexibility puts a premium on enlightened leadership techniques to deal with the constantly changing organizational context, availability of new technology, and dynamically changing requirements that are the hallmarks of the complex system world.

Storyboarding the National Airspace System
Mr. Bilicki will present how “Storyboarding” can be used to understand the NAS. Animation will be used to demonstrate how the NAS Architecture can be understood from the highest functional level to the most detailed design level. This is accomplished without the use of expensive software tools and software development. Other examples include a commercial flight takeoff scenario with voice over and the latest concept of Data Communications (DATACOMM), both of which will illustrate a sequence of events as the flight transits the NAS. The audience may garner applicability of “Storyboarding” towards demonstrating ideas, Concepts of Operation, Requirements Analysis, and as an aid to Developmental and Operational Test briefings.
