 | The propagation of terahertz (THz) band radiation through the atmosphere is a topic of increasing interest as advanced passive and active imaging systems are developed that operate in this spectral region. Much of the impact of the boundary layer atmosphere in this band is due to water vapor absorption, which is very strong even in atmospheric window regions. Most of the effect of atmospheric water vapor is due to the ... |

|
| The use of pelletized asphalt technology to produce airfield-quality hot-mix asphalt (HMA) is evaluated in this study. The pelletization process produces HMA mix components (asphalt cement, fine aggregate, fiber and polymer) as a pre-manufactured product that could be shipped at ambient temperature to a remote location. There, it can be introduced to locally-produced, heated coarse aggregate in a continuous or batch plant. Two HMA mix types known to provide high ... |

Patrick Jungkunz; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The search and target acquisition models used in current military simulations for visual detection of ground soldiers are empirical. Although taking into account human performance data collected in field trials, they do not attempt to realistically model human search behavior. This, however, is necessary to achieve realistic target detection performance, including such phenomena as false positive detections at realistic locations. Working towards this goal, this research creates a model of ... |

 | Optical devices interrogated with a laser in the appropriate band can exhibit strong, deterministic reflections of the incident beam. This characteristic could be exploited for optical target detection and identification. The distribution of reflected power is strongly dependent on the geometry of the interrogation scenario, atmospheric conditions, and the cross section of the target optical device. Previous work on laser interrogation systems in this area has focused on analytic models ... |

| In this experiment, spider webs demonstrated their suitability as passive bioaerosol collectors. For spider webs to be considered suitable passive collectors webs had to satisfy three basic conditions; (1) collection of microorganisms without discrimination based on species or size, (2) collection under variable environmental conditions, and (3) saturation avoidance in the presence of strong microbial launching sources. Four field sampling locations were used, a waste water treatment facility, a commercial ... |

| The United States Forestry Service (USFS) currently uses solid powder gelling agents to create gelled gasoline for controlled burns. Because these gelling agents are difficult to mix with gasoline, nonhomogeneous solutions result. The inconsistency in the gelled gasoline results in larger quantities of it being used for controlled burns and also worsens the safety hazards associated with gel dispersion. Therefore, the project objective was to solve these problems by producing ... |

| The outcome of a field evaluation of decontamination of a wide-body aircraft using AeroClave's thermal decontamination system both as a stand-alone technology and as a means of delivering STERIS vaporized hydrogen peroxide (VHP )* is discussed. The report is submitted in the context of a decontamination technology selection exercise, laboratory work conducted on the efficacy of thermal decontamination, and as a follow-on to a field evaluation performed previously on a ... |

| A test battery to assess mental flexibility was developed based on Sternberg's theory successful intelligence (1985). New mental flexibility assessment instruments were developed and underwent formative and summative evaluation. The newly developed mental flexibility tests showed adequate reliability, and preliminary evidence of construct- and criterion-related validity. One mental flexibility factor explained 70% of variance in the test battery and was differentiated from the latent factor underlying divergent and convergent measures ... |

| To transition existing prototype autonomous profiling nutrient analyzers into commercial products that can be readily deployed on autonomous profiling moorings, coastal gliders and propeller driven unmanned underwater vehicles and used for sustained, autonomous ocean observations of chemical distributions and variability. A series of issues have been identified that need to be addressed to convert prototype nutrient analyzers into commercial units that can be widely used by the community for sustained ... |
