Description
Welcome to the Modeling Virtual Environments and Simulation (MOVES) Institute at the Naval Postgraduate School in Monterey, California. MOVES is an interdisciplinary research and academic program dedicated to education and research in all areas of defense modeling and simulation and has a degree programs leading towards a Master of Science or Doctor of Philosophy in MOVES. The MOVES Institute has its roots in the NPSNET Research Group founded in 1986. NPSNET was the original low-cost, government-owned, SIMNET and DIS compatible visual simulator. It was widely used around the world and was integrated into many government programs over its lifetime. While MOVES was founded in 2000, MOVES as an academic program was founded in 1996 with the launch of the Master of Science program, followed by the Doctoral program in 1999. The Institute is intended to be a mix of the strong analysis tradition of the Operations Research Department and the simulation, training, and software development expertise of the Computer Science Department. Most notably, MOVES was the birthplace of America’s Army. Sponsored by the Office of the Assistant Secretary of the Army: Manpower and Reserve Affairs, America’s Army was our first venture into the use of video game technology for defense applications. Development has since left the Institute, but many millions of players have downloaded and played America’s Army since 2000.

    Effects of streaming video quality of service on spatial comprehension in a reconnaissance task
    (2001) Darken, Rudolph P.; Kempster, Kurt; Peterson, Barry; Modeling, Virtual Environments, and Simulation Institute (MOVES); Computer Science (CS)
    It has been proposed that if we could configure individual personnel with micro-video cameras and wireless communications such that they could transmit a video stream of what they were seeing to a remote observer, this would be an enormous improvement in reconnaissance and battlefield command and control. We looked ahead, based on current video and wireless communications technologies and trends to what we can expect to have available in terms of streaming video quality of service (QOS) and we used those predictions to conduct an experiment to determine if this assertion of improvement is true. Participants viewed a digital video with a data rate associated with a given transmission technology. They were asked to maintain their orientation by tracking the position of the camera on a paper floor plan diagram. They were also asked to identify a number of objects and place them in the correct room on the floor plan. The results show that participants found all conditions except the live walkthrough control condition to be extremely difficult with poor performance on both the spatial orientation task and the object identification task. Bandwidth does affect error as increased data rate improves performance. Rapid head rotations seem to be the largest contributor to disorientation, especially with low data rate video. Our results suggest that simply supplying video feedback to a remote observer may be useless at best or possibly damaging at worst. What is needed is not necessarily more bandwidth, but better interfaces and tools to help observers to remain oriented such that they can extract what is needed from the video stream.

    Gravitational Effects of Earth in Optimizing Delta V for Deflecting Earth-Crossing Asteroids
    (2001-10) Ross, I. Michael; Park, Sang-Young; Porter, Scott D. V.; Modeling, Virtual Environments, and Simulation Institute (MOVES); Mechanical and Aerospace Engineering (MAE); Graduate School of Engineering and Applied Science (GSEAS); Department of Aeronautics and Astronautics
    Analyses incorporating the gravitational effects of Earth to calculate optimal impulses for de ecting Earthcrossing asteroids are presented. The patched conic method is used to formulate the constrained optimization problem. Geocentric constraints are mapped to heliocentric variables by the use of the impact parameter. The result is a uni ed nonlinear programming problem in the sense that no distinctions are made for short or long warning times. Numerical solutions indicate that the delta V requirements are considerably more than those of the previously published two-body analysis that excluded third-body effects. Generally speaking, the increments in the minimum delta V due to the gravitational effects of the Earth are large (by asmuch as 60%) for near-Earth asteroids, and the errors diminish for orbits with large eccentricities (e>0.7). Some interesting results for short warning times are also discussed.

    Extensible modeling and simulation framework (XMSF) 2004 project summary report
    (Monterey, California. Naval Postgraduate School, 2005) Blais, Curtis L.; Brutzman, Don; Drake, David; Moen, Dennis; Morse, Katherine; Pullen, Mark; Tolk, Andreas; Modeling, Virtual Environments, and Simulation Institute (MOVES); Modeling, Virtual Environments, and Simulation Institute (MOVES)
    The Extensible Modeling and Simulation Framework (XMSF) is defined as a composable set of standards, profiles and recommended practices for web-based modeling and simulation. Markup languages based on XML, Internet technologies, and Web services are combining to enable a new generation of distributed M&S applications to emerge, develop and interoperate. The purpose of this task is to develop the technical framework, coordinate with existing public standardization efforts, and demonstrate distributed exemplars of the developed framework. This report describes work accomplished in 2004 by the XMSF project team consisting of Naval Postgraduate School Modeling, Virtual Environments, and Simulation (MOVES) Institute, George Mason University (GMU), Science Applications International Corporation (SAIC), and Old Dominion University/Virginia Modeling, Analysis, and Simulation Center (ODU/VMASC). Principal areas of work included ongoing community education and development activities through conference and workshop participation, liaison with relevant standards organizations, and development of exemplar applications demonstrating the technical approaches and applicable standards relevant to XMSF precepts. The report proposes follow-on efforts for 2005, including continuation of current efforts and further standardization work with multicasting, web-enabled IEEE 1516 Run-Time Infrastructure, data modeling in C2 and M&S systems, and executable architectures.

    Formal Analysis of Elastically Supported Beam Columns
    (1966) Brock, John E.; Modeling, Virtual Environments, and Simulation Institute (MOVES); Mechanical and Aerospace Engineering (MAE); Graduate School of Engineering and Applied Science (GSEAS)
    A method is presented for the systematic analysis of elastically supported beam-columns or tie-bars in which formal notational devices simplify the handling of complicated discontinuous lateral loads. Various relationships between axial load and support modulus are treated and three particular cases (fixedfixed, pinned-pinned, and free-free ends) are exhibited.

    Eliciting Knowledge from Military Ground Navigators
    (ResearchGate, 2000) Peterson, Barry; Stine, Jason L.; Darken, Rudolph P.; Modeling, Virtual Environments, and Simulation Institute (MOVES)
    The N.D.M. framework is appropriate for the study of military ground navigators. Our characterization of expertise evolved from initial group to subsequent individual interviews. We describe our application of the C.D.M. to this domain and present the resulting Cue Inventory, Situation Assessment Record and Key Decision Requirements. We expose and discuss the dynamics of organization and methods we faced while gaining access to the participant community and conducting the study. The immediate goal is to apply the results to the development of navigation training interventions, so we conclude by discussing representations of navigation expertise that are suited for such applications.

    Maker Space Collaboration
    (Naval Postgraduate School, 2020) MOVES; Gunduz, Emre; Sadagic, Amela; Tsolis, Kristen; Modeling, Virtual Environments, and Simulation Institute (MOVES)
    USMC innovation labs, along with additive manufacturing (AM) cells, will have a significant impact on future Navy and Marine operations, and these spaces can be important catalysts for learning, collaborating, and experimenting with rapid prototyping and AM. The same groups can also accelerate the adoption of new technologies within the USMC. Providing those spaces with necessary infrastructure, guidance, and support material are crucial to avoid obstacles to technology adoption and maximize the potential for their sustainment and growth. This project expanded our understanding of the US Marine Corps Innovation Labs with a special emphasis on lab infrastructure and service members' capacity to engage with new technologies, conditions, and needs of USMC. The research addressed the topics of innovation mission of the Marine Maker Movement, types of innovation approaches, technologies, and hands-on lab experiences that would be best used for the Innovation Labs, and the way those experiences should be disseminated.
