| Software protection is of great interest to commercial industry. Millions of dollars and years of research are invested in the development of proprietary algorithms used in software programs. A reverse engineer that successfully reverses another company's proprietary algorithms can develop a competing product to market in less time and with less money. The threat is even greater in military applications where adversarial reversers can use reverse engineering on unprotected military ... |

| A series of simplified scenarios is investigated whereby an optical flow - balancing guidance law is used to avoid obstacles by steering an air vehicle between fixed objects/obstacles. These obstacles are registered as specific points that can be representative of features in a scene. The obstacles appear in the field of view of a single forward looking camera. First a 2-D analysis is presented where the rate of the line ... |

| This research examined the theory and application of using discrete multi-tone (DMT) frequency-domain equalization (FEQ) with communications systems that inherently possess null-tones in their respective transmission frequencies. DMT-FEQ relies on null-tones to equalize a non-ideal channel. A Hadamard encoded code division multiple access (CDMA) communications system with up to 32 synchronous users and a transform domain communications system (TDCS) with one user were investigated. Both communications systems were simulated while ... |

| A space-time optimal power schedule for multiple distributed multiple-input multiple-output (MIMO) links without the knowledge of the instantaneous channel state information (CSI) at the transmitting nodes is proposed. A readily computable expression for the ergodic sum capacity of the MIMO links is derived. Based on this expression, which is a non-convex function of power allocation vectors, a projected gradient algorithm is developed to optimize the power allocation. For a symmetric ... |

| The Australian Defence Force (ADF) is committed to transitioning, over time, to Network Centric Warfare (NCW). NCW sees the elements of the ADF as "nodes" in a network. The capability of such a force is determined not so much by the individual capabilities of each node, but by the systems properties of the network as a whole. In this paper, we provide a taxonomy of possible NCW architectures, in order ... |

|
| We propose a context-sensitive probabilistic modeling system (COSMOS) that reasons about a complex, dynamic environment through a series of applications of smaller, knowledge-focused models representing contextually relevant information. COSMOS uses a failure-driven architecture to determine whether a context is supported and consequently whether the current model remains applicable. The individual models are specified through sets of structured, hierarchically organized probabilistic logic statements using transfer functions that are then mapped into ... |

This feature set has evolved to maximize general ASR performance within a Bayesian classifier framework using a common feature space. Now, however, with the advent of the PDF projection theorem (PPT) and the class-specific method (CSM), it is possible to design features separately for each phoneme and compare log-likelihood values fairly across various ... |

| In most sensor network applications, the vector containing the observations gathered by the sensors lies in a space of dimension equal to the number of nodes, typically because of observation noise, even though the useful signal belongs to a subspace of much smaller dimension. This motivates smoothing or rank reduction. We formulate a convex optimization problem, where we incorporate a fidelity constraint that prevents the final smoothed estimate from diverging ... |

| Results from large-scale hydraulic fluid spray fire tests have been compared with simulations of those tests using the Fire and Smoke Simulator (FSSIM) model. Using a model calibration data set, the sensitivity of FSSIM to several key inputs was evaluated; for the critical heat release rate (HRR) parameter, an adjustment factor was estimated to correct for unburned fuel. The resulting input parameters were then applied to similar data sets and ... |

| The Hubble Ultra Deep Field (HUDF) contains a significant number of B-, V-, and iota'-band dropout objects, many of which were recently confirmed to be young star-forming galaxies at Z approximately equal 4-6. These galaxies are too faint individually to accurately measure their radial surface-brightness profiles. Their average light profiles are potentially of great interest, since they may contain clues to the time since the onset of significant galaxy assembly. ... |

| Discovery in science is the generation of novel, interesting, plausible, and intelligible knowledge about the objects of study. Literature-related discovery (LRD) is the linking of two or more literature concepts that have heretofore not been linked to produce novel interesting, plausible, and intelligible knowledge (i.e., potential discovery). Two major variants of LRD are open discovery systems (ODS), where one starts with a problem and generates a potential solution (or vice ... |
