Department of Defense (DoD) acquisition policy requires testing throughout the systems development process to ensure not only technical certification but also mission effectiveness. Complexity within each new system, as well as composition into families of systems and systems of systems, combines with the extensive use of simulation in the design phase to multiply the challenges over traditional interoperability testing methodologies and processes. In this paper, we present a new methodology and process that integrates system development and testing intended to address the new challenges. The approach goes beyond current software development paradigms in that it rests upon and exploits dynamic systems theory, a modeling and simulation (M&S) framework, and model-continuity development concepts. The process can be applied to development of systems from scratch or in a form of reverse engineering in which requirements have already been developed in an informal manner. We illustrate the...

ABSTRACT: Link-11 is a tactical digital communication network standard deployed in military platforms now for several decades. The standard employs the digital modulation technique Differential Quadrature Phase Shift Keying (DQPSK) to encode formatted binary messages (M-series messages) onto an audio channel, which are then modulated and transmitted over a radio communications network. Testing of the various systems that use this communications network requires either a fully operational RF network or exchange of the audio-encoded data over a voice channel. An alternative is to send and receive over an IP network, by encoding and decoding the audio from a Data Terminal Set (DTS) that is part of the normal operational equipment. This allows the test community to interconnect distant test sites over IP networks using this robust connectivity for message exchanges. This facilitates interoperability testing at the data and applications level where RF and audio connectivity is not availa...

Department of Defense acquisition policy requires testing throughout the systems development process to ensure not only technical certification but also combat effectiveness. Complexity within each new system, as well as composition into families of systems and systems of systems, combines with the extensive use of simulation in the design phase to multiply the challenges over traditional interoperability methodologies and processes. Existing single-thread conformance certification processes, such as those conducted at the Joint Interoperability Test Command, provide a solid foundation on which to build a more robust framework for distributed interoperability testing from a holistic perspective. The framework recognizes that system development must increasingly rely on modeling and simulation (M&S) while addressing some critical impediments to the efficient use of M&S in distributed testing environments. We discuss the framework and its theoretical and practical formulation, offerin...

Star light deflection near the sun of 1.75 arcseconds during a solar eclipse has been attributed to post-Newtonian physics for over a century; however, this can alternatively be shown as a geometric resultant of the Sun-Galaxy interface very near the Sun, and specifically conforming exactly to the curvature of the Sun’s orbit in the galaxy. It is clearly demonstrable through basic geometry that the post-Newtonian light deflection is simply due to the Sun-Milky Way Galaxy EquiPotential (EP) interface, and that a simple ratio exists to explain the galactic origin of the deflection effect. This report examines data and reviews solar eclipse deflection tests for their geometry as evidence for this alternative explanation, which we now add as a component model to Diffusion Gravity(DG) theory; moreover, we present a corresponding mechanism for deflection of light near the Sun due to virtual particle behaviors for photons. This effect of gravitational equipotential surfaces on the propagat...

: This article provides perspectives on how a test organization can organize and plan for enterprise-wide adoption of advances in emerging technologies and techniques, whether developed in-house or acquired from external sources. This article enumerates capabilities that greatly enhance a test organization's ability to support the impending testing demands from such GIG/SOA-based projects and presents an overarching strategic plan for integrating existing test technologies, identifying enterprise-wide technology gaps, and coordinating the development and acquisition of new test capabilities to greatly accelerate their readiness to meet impending net-centric testing challenges. The plan discussed in this article includes short-, medium-, and long-term horizon components to acquire or improve current test capabilities and offers a layered architecture that provides a framework for capability acquisition. Test organizations can incentivize their contractors to exploit the composabi...

Diffusion Gravity theory has shown in previous works that the constant velocity profiles of galaxies may be a direct result of equipotential “locking” of stars to the zero-potential balance point between the star and its parent galaxy. This hypothesis was incorporated into the Diffusion Gravity model in a previous paper [9] along with the integral mechanism of gravitational attraction to explain those constant velocity profiles that are otherwise attributed to “dark matter”. In this current research report, DG postulates other effects between the Sun-Mercury pair and the Milky Way Galaxy (MWG), and compares them with Mercury precession models from numerous other researchers, some or all of which can account for the precession advance of the perihelion of Mercury. In particular, the acceleration-torque effect of the MWG should also advance precession of the perihelion, thus contributing and adding to the total calculated by mass-ring models to arrive at the measured total precession ...
