This half-day workshop will demonstrate the use of a lottery-based simulation to teach students how to run an agile project by practicing the routine of daily meetings, coordination by mutual adjustment and tracking and reporting of progress. The objective of the simulation is twofold: to teach students the process' mechanics and provide them with insights about the implications on performance and...
NASA has engaged in collaborative research with the FAA and many other stakeholders in government, industry, and academia to explore the concepts and requirements necessary to enable the safe and scalable application of small unmanned aircraft systems (UAS) in low-altitude airspace. In this effort, the UAS Traffic Management (UTM) project has developed a multi-faceted simulation component that supports...
At the Institute of Computer Science at Silesian University in Opava is developed multi-agent system (MAS) in the form of a swarm of unmanned aerial vehicles (UAV). For the simulation of the multi-agent system was proposed double-layer software environment. As the presentation layer was selected the simulation tool Webots that enables detailed parameter settings of an individual agent (flying device...
Application of neural networks for direct prediction of lateral-directional force and moments coefficients from the measured flight data of the research aircraft is proposed in this paper. Proposed model of neural networks appears to be a suitable practical approach to develop relationship between flight variables. This relationship eliminates the need of aerodynamic model as well as thrust model...
This paper explains how simulation can contribute to the airborne radars qualification. Thales Airborne Systems has developed a wide range of the simulation tools over the last few years and a new method called “Smart Qualification” is now deployed within the company. This method and these tools have demonstrated their efficiency. The maturity of the radar system to be qualified is dramatically increased...
This paper presents an automatic airport check-in KIOSK system. This work is done collaboratively by four subsystems, which are Airline Reservation, Credit Card Verification, KIOSK and Customer Command Input, in an action interactive manner. To reduce the risks or issues that often occur in complicated systems, a Four Subsystems in Parallel (FSIP) method has been proposed. Customers can benefit generality...
In development and support of complex products such as power plants, automotive vehicles, or aircrafts, modeling and simulation has become an important activity as a basis for knowledge capture. Simulation is used in several steps of the product lifecycle; for evaluation of early design, for system verification, and for user training. With emerging techniques such as tools for high-level modeling,...
A roof-top scaled experimental wind turbine was simulated in FLUENT. Meshing technique for wind turbine blades was studied and a suitable mesh was achieved. The SST k-ω model was set to be the turbulence model in FLUENT. Detailed settings were studied to maintain a convergent and more accurate simulation. The simulation predicted the wind turbine power coefficient in different tip speed ratios. The...
This paper describes how to evaluate the impact of a cyber attack on a mission. We accomplish this by computing impact as the changes to mission measures of effectiveness, based on the reported effects of a known or suspected attack on one or more parts of the information technology (IT) supporting the mission. Our previous papers have described our goals for computing mission impact and the choices...
The paper describes the engine valve-train mechanism's dynamic analysis method, and introduces how to make dynamic simulation of it, and then makes the conclusions from the simulation results. In the process of simulation, first engine valve-train mechanism is modeled by CATIA software, and then models are imported into ADAMS software, so as to simulate the movement of engine valve-train mechanism...
This work investigates the analysis methods of the main load of the wind turbine blade under the blade coordinate. By simulating the different scenarios, such as the wind statuses, the air densities and gravity constants, using the FAST simulation commercial software, the loads of the wind turbine are compared. Based on the comparison, this paper point out the option about the torque in the blade...

In the overall design and class kit design of the software, several subsystems, such as the perception, decision-making, operation, dynamic characteristic of the pilot, and flight control system, aerodynamic characteristic, engine and dynamic model of the aircraft are considered and...
Interoperability of constituent systems is the primary challenge for a large-scale distributed Live-Virtual-Constructive (LVC) simulation activity. The grand challenge is to integrate, for the first time, all aspects of interoperability necessary not only to enable but to ensure interoperability throughout an large-scale LVC system. Previously, a handful of these aspects of interoperability have been...
