 | Simulating the behavior of sensor applications in a heterogeneous network or under diverse environmental conditions is particularly challenging. In this paper, we present the design and implementation of TiQy, a scalable framework that allows unmodified TinyOS applications to be evaluated in a diverse set of operating conditions, including heterogeneous networks. We validate TiQ against MoteLab, a physical sensor network testbed, and show that TiQ can predict the behavior of the ... |

| The United States Air Force has advanced fighter aircraft that lose the ability to operate in a large portion of their operating flight envelope when an air data system failure is experienced. These aircraft are reverted to a fixed set of standby-gains that limit their maneuverability, degrade handling qualities, and increase susceptibility to departure. The purpose of this research was to determine if three alternative methods of standby-gain-scheduling could provide ... |

| Technical skill is at the core of surgery. Surgical training typically lasts for a specified time period or number of procedures. This approach produces surgeons with considerably variable skill levels. Also, training on patients is becoming unacceptable for patient safety. In contrast, pilots and other non-medical personnel are trained to criteria on simulators to ensure skill proficiency in their MOS prior to reporting for duty. Proficiency levels are objectively established ... |

| New ship manning concepts have resulted in new demands and changing roles for personnel assigned to damage control. The changing force structure requires that designers and operators understand the capabilities of damage control teams. This includes the design, equipment, and doctrinal requirements needed for an acceptable level of ship recoverability. Limited formal structures and validated methods for assessing such capabilities exist. Methods to assess readiness and training requirements suffer from ... |

| A novel color-transformation method converts daytime scenes into night-vision goggle images suitable for realistic nighttime training. To date, nighttime training using flight or driving simulators has been hindered by the lack of typical night-vision goggle (NVG) rendering. NVG performance is often simulated in training vehicles by converting daytime images into black and white, and displaying the resulting scene in green. However, this approach does not consider that NVG images are ... |

| Military plan validation is typically a long-drawn process requiring planners to validate their plans using anticipated scenarios or through military exercises. While military exercises provide realistic simulation of the plan, it is often the most expensive way of validating a plan. On the other hand, although using anticipated scenarios is relatively cheaper, the robustness of the validated plans is dependent on the extensiveness of the scenarios that they are validated ... |
