Approved for public release, distribution unlimited; Modern Modeling and Simulation (M&S) techniques offer flexible, economical capabilities for assessing naval installation security systems, equipment and Concepts of Operations (CONOPS). These tools are useful for assessing risk and vulnerability in a broad range of operational situations and in response to a spectrum of threat scenarios. Of particular interest to both military and homeland-defense analysts is the combined shore-side and water-side protection of naval and harbor facilities. In August of 2005, the NPS MOVES Institute was funded by the Naval Facilities Engineering Service Center (NFESC) to investigate and develop such an analytic tool. This report describes the work accomplished during Phase II of the Modeling and 3D Visualization for Evaluation of Anti-Terrorism/Force Protection Alternatives project in order to achieve that goal. Waterside protection includes surveillance (detection and assessment), delay (e.g., barriers), and warning and response means (e.g., patrol craft). The purpose of the Phase II effort was to develop an analysis tool that supports assessment of the effectiveness of various sensor, barrier, and response systems to enable decision-makers to make good judgments on what to purchase and employ. For example...

Approved for public release, distribution unlimited; The initial X3D Earth Technical Requirement Workshop called together leading researchers, developers and industry experts to determine a broad set of technical requirements that will be necessary to construct an X3D Earth. This workshop was held 14-15 November 2006 at the Naval Postgraduate School (NPS) in Monterey, California, USA. The main goal in the creation of an Extensible 3D (X3D) Earth will be achieved by Web3D Consortium members who are preparing to build a standards-based suite of software tools usable by governments, industry, scientists, academia and the general public. X3D mappings of world terrain, cartography and imagery will be made available for use in any scene, making it easy to geospatially reference and share X3D models. Open standards, the Web architecture, utilization of the Extensible Markup Language (XML) and open protocols will be leveraged throughout. Both commercial and open-source software codebases will be able to utilize these best practices and contribute to these shared assets. The goal of this technical requirements workshop was for participants to identify and prioritize the technical requirements, available capabilities, open challenges and strategic partnerships needed for a Web3D working group to execute this ambitious project. Emphasis was placed on extensibly adapting existing resources and in cooperation towards achieving shared goals...

Approved for public release, distribution is unlimited; Autonomous Underwater Vehicles (AUVs) are now being introduced into the fleet to improve Mine Warfare capabilities. Several AUVs are under government-contracted development. Mission planning and data reporting vary between vehicles and systems. This variance does not pose an immediate problem, as only one AUV is currently in production. However, as more AUVs are put into production, commands will begin to get multiple AUVs. Without a single mission command language, multiple systems will require familiarity with multiple languages. Extensible Markup Language (XML) and related technologies may be used to facilitate interoperability between dissimilar AUVs and extract and integrate mission data into Navy C4I systems. XML makes archive maintenance easier, XML documents can be accessed via an http server, and, in root form, XML is transferable on the fly by stylesheet. This thesis presents an XML-based mission command for the command and control of AUVs. In addition, this thesis discusses XML technology and how XML is a viable means of achieving interoperability. Furthermore, this thesis provides an example mission file using existing software, and demonstrates the future of XML in AUV technology. Finally...

Approved for public release; distribution is unlimited.; Approved for public release; distribution is unlimited.; Inverse Synthetic Aperture Radar (ISAR) provides full range detection and classification of sea and air based targets through two-dimensional range-Doppler imaging. The Naval Postgraduate School has developed a custom integrated circuit that can simulate false ISAR images in order to fool enemy ISAR platforms. To validate specific hardware choices within this design, this thesis explores the effect on image quality of an overflow occurring within the final 16-bit summation adder of this circuit. Three solutions to the problem of overflows are presented and analyzed. The logical extension of ISAR development, that of three-dimensional target imaging, is next presented through the discussion of 3D monopulse radar, 3D interferometric ISAR, and a 3D, three receiver ISAR. The relative strengths of each approach are compared, along with both MATLAB and X3D software models created for one specific 3D ISAR implementation. Through the superposition of 2D ISAR images it is shown how 3D ISAR images may be created. Moreover, emphasis is placed on using this knowledge to both enhance current 2D ISAR techniques and to modify the false-target chip to handle 3D ISAR return signals. The thesis concludes with a study of Non-Uniform Rational B-Splines...

Approved for public release, distribution unlimited; Adopting Extensible Markup Language (XML) and Hypertext Transfer Protocol (HTTP) are key steps to accommodate the evolution of Internet technologies. While HTTP is already a proven standard communication protocol responsible for the rapid expansion of the World Wide Web, XML provides general mechanisms for determining validatable documents and addresses several deficiencies of HTML regarding diverse document structure and content. XML and HTTP together provide many of the essential capabilities associated with database engines. The Modeling, Virtual Environments and Simulation (MOVES) Institute of the Naval Postgraduate School (NPS) is continuing to build a database of 3D tactical scenarios and using X3D and VRML tools. The configuration parameters and statistical results of these scenarios are XML documents. For a better understanding and usability of these results by the end users, a Webbased application stores and manipulates these XML document. This thesis develops a server-side application that can store, serve, and annotate tactical scenarios for X3D operational visualization and anti-terrorist training by using XML and HTTP technologies. The experimental demonstration for this work is the prototypical Anti-Terrorism/Force Protection (AT/FP) simulation model developed by Lieutenant James W. Harney...

Approved for public release, distribution unlimited; Approved for public release; distribution is unlimited.; A common problem between Military applications and operators is the consistent and meaningful exchange of data. Currently, several models and simulations exist for the purposes of training and analyzing military data. Due to the absence of an agreed-upon standard with which to represent unit data, much is lost during interchange and applications are not maximized. This thesis is a step towards a solution. Extensible Markup Language (XML) technology has been widely accepted as a standard for representing information in such a way that it is self-documenting, self-validating and platform independent. By using the Command and Control Information Exchange Data Model (C2IEDM), formerly known as Generic Hub, and XML it is possible to develop a representation of unit data that is extensible and broadly useable by tactical systems and human operators alike. This thesis approaches the problem exploring the Model Driven Architecture (MDA) and the Extensible Modeling Simulation Framework (XMSF) as possible overarching architectural concepts for a global solution. The C2IEDM is used as the core data interchange model for this research and applies XML technologies...

Approved for public release; distribution is unlimited; S tasks. Discrete Event Simulation (DES) often involves repeated, independent runs of the same models with different input parameters. A system which is able to run many replications quickly is more useful than one in which a single monolithic application runs quickly. A loosely coupled parallel system is indicated. Inexpensive commodity hardware, high speed local area networking, and open source software have created the potential to create just such loosely coupled parallel systems. These systems are constructed from Linux-based computers and are called Beowulf clusters. This thesis presents an analysis of clusters in high-performance computing and establishes a testbed implementation at the MOVES Institute. It describes the steps necessary to create a cluster, factors to consider in selecting hardware and software, and describes the process of creating applications that can run on the cluster. Monitoring the running cluster and system administration are also addressed.

The ability to efficiently transfer information among tactical systems is essential for network-centric operations. However, maintaining interoperability among heterogeneous networks and applications is a challenging issue, especially for large enterprises such as the US Department of Defense and NATO. Each of these organizations maintain extensive communication networks of tactical systems that process and manage all types of data. Additional complexity is added when considering that many systems are built with a variety of proprietary or legacy data formats. Establishing and maintaining interoperability is difficult. Using XML, many interoperability issues can now be successfully addressed. XML provides a self-describing way to effectively structure information that can be applied to compose diverse tactical communications. However, XML is inefficient for network transmission since it uses a text-based format which can consume more memory (and thus more bandwidth) than binary equivalents. In addition, parsing text-based documents is slow and computationally expensive. One potential solution is to use GZIP to reduce the file size before transmission. Unfortunately, this solution has limitations since it often provides suboptimal compression and also requires additional processing time when extracting data. Recent standardization efforts have identified promising new encodings for XML that use binary representations to reduce parsing time...

Approved for public release, distribution unlimited; Todayαs planning and modeling systems use two-dimensional (2D) representations of the threedimensional (3D) battlespace. This presents a challenge for planners, commanders, and troops to understand the true nature of the battlespace. This thesis shows how 3D visualization can give both operation planners and executors a better understanding of the battlespace that can augment todayαs 2D systems. Automatic creation of a 3D model for an amphibious operation allows the planner to view an operation order as a whole, from different perspectives. Recommended changes can be made and their effects immediately known. Warfighters can use the same tools for mission preparation and review. The United States and NATO nations use the Land C2 Information Exchange Data Model (LC2IEDM), formally known as the Generic Hub, as a common method for exchanging data between independent systems. As part of the Scenario Authoring and Visualization for Advanced Graphical Environments (SAVAGE) project, this research presents an integrated Web access and 3D visualization strategy for Department of Defense (DOD) tactical messaging and operation orders using the Generic Hub data model and the Extensible Markup Language (XML). A number of alternative yet consistent ways to represent an amphibious operation scenario demonstrate the power...

The business drivers within managed care are mandating that physicians have point-of-care access to medical reference data, patient specific data, formularies, treatment protocols, and billing/coding information. One emerging technology that has the potential to provide this access with little economic investment is the mobile Personal Digital Assistant. The authors address a variety of wireless technologies and security concerns regarding real-time access to patient data. The family practice staff at the Naval Hospital Lemoore explored and contrasted the capabilities of commercially available PDAs, wireless interfaces, and medical software applications to ascertain their value within the Military Health System. A production-ready interface between the Composite Health Care System and the Nutrition Management Information Server demonstrates the potential for eliminating the difficulties associated with documenting patient encounters and capturing charges. Survey tools generate a requirements standard for deployment of this technology within the Military Health System on an enterprise-wide scale with a hybrid approach to packaging based on functionality. The authors recommend the Military Health System embrace this technology as a means to realize its vision of best value health services.

A critical bottleneck exists in Autonomous Underwater Vehicles (AUV) design and development. It is tremendously difficult to observe, communicate with and test underwater robots, because they operate in a remote and hazardous environment where physical dynamics and sensing modalities are counter intuitive. An underwater virtual world can comprehensively model all salient functional characteristics of the real world in real time. This virtual world is designed from the perspective of the robot, enabling realistic AUV evaluation and testing in the laboratory. Three-Dimensional real-time computer graphics are our window into that virtual world. Visualization of robot interactions within a virtual world permits sophisticated analyses of robot performance that are otherwise unavailable. Sonar visualization permits researchers to accurately 'look over the robot's shoulder' or even 'see through the robot's eyes' to intuitively understand sensor-environment interactions. Extending the theoretical derivation of a set of six-degree-of-freedom hydrodynamics equations has provided a fully general physics-based model capable of producing highly non-linear yet experimentally-verifiable response in real time. Distribution of underwater virtual world components enables scalability and real-time response. The IEEE Distributed Interactive Simulation (DIS) protocol is used for compatible live interaction with other virtual worlds. Network connections allow remote access...

In large measure, the vision of making it easier to create and use 3D spatial data has been achieved through The Extensible 3D (X3D) Earth project. This project created a standards-based 3D visualization infrastructure for visualizing all manner of real-world objects and information constructs in a geospatial context. The ability to archive models using stable commercial tools and noncommercial international standards ensures that 3D work can remain accessible and repeatable for many years to come. In this presentation we shall describe how we leveraged the NPS Supercomputer 'hamming' to defray the huge investment involved in the project through server-side preparation of content, interlocking/addressable URL schemes, ability to add new X3D Earth content, ability to efficiently mirror resources, streaming of relevant X3D Earth data, etc. over high-performance networks such as CENIC.
