 | Computer-generated forces (CGF) are an important part of today's training devices. When linked to manned simulators, these computer-generated entities provide a dynamic and realistic environment for interaction of human participants. It also allows the addition of many players, which might not be cost effective using many networked, manned devices as an alternative. These CGFs are comprised of two specific objects: equipment model and a behavioral or cognitive model. The equipment ... |

 | Anthropomorphic dummies are mechanical surrogates of the human body. Dummies are also called anthropomorphic test devices (ATDs) and manikins. They are used as test devices by the automotive and aircraft industries and regulatory bodies, and the military to evaluate vehicle safety in crash and escape system environments. Dummies are designed to perform two basic functions. Earlier versions were used strictly for loading the vehicle dynamically, and required only weight and ... |

 | Effectively scanning and interpreting flight instruments are crucially important skills for pilots. Despite the facts that much of pilot training is devoted to developing an effective scan and that virtually all successful pilots have effective scans, there is surprisingly little objective information about instrument scan patterns. Most studies of scan patterns have used either pilots' self reports of their scanning or measurements made with relatively invasive eye tracking procedures, procedures ... |

 | A validation sample of 535 male Canadian Forces (CF) was measured. Unfortunately, the measuring sites chosen by the CF were atypical and led to a non-random sample. Prior to discovering this bias, the data were utilized to explore several alternative matching procedures. The most successful was a subject-to-subject individual matching procedure using age, height and weight. However, waist circumference continued to differ significantly between the CF validation subjects and their ... |

 | Fleet aviators consistently rank situational awareness (SA) as a critical mission concern. SA, although elusive, must be understood and improved for the sake of mission effectiveness, expansion, survivability, and safety. The essence of SA is the reception, manipulation, and use of information. SA encompasses the physical, mental, psychological, social and physiological capabilities of the human operator. The operator must sense and perceive variables in the environment and then process that ... |

Previous human entities were exercised as individual entities in the virtual environment. Yet there are many applications (i.e. shipboard damage control, amphibious landings, helicopter vertical assaults) where human entities need to mount other vehicles within the virtual environment. The approach taken was to re-engineer the Naval Postgraduate School's Shiphandling Training Simulator (SHIPSIM) ... |

Researchers who apply this methodology to digital imagery currently have no X Windows-based graphic user interface software package through which they may aggregate, test, and demonstrate their steganography programs. Such a package would contain features to encode data to ... |

 | Since the inception of modern simulation, the designers and users of training devices have attempted to replicate as many physical and functional stimuli as possible in the training device. There are three primary impediments to this activity: our frequent inability to specify the kinds of stimuli that are required, our technological difficulty in replicating some stimuli, and the cost of replicating stimuli. The constraints cited above have led the training ... |

 | Sigmoid type belief networks, a class of probabilistic neural networks, provide a natural framework for compactly representing probabilistic information in a variety of unsupervised and supervised learning problems. Often the parameters used in these networks need to be learned from examples. Unfortunately, estimating the parameters via exact probabilistic calculations (i.e, the EM-algorithm) is intractable even for networks with fairly small numbers of hidden units. We propose to avoid the infeasibility ... |
