 | Quantify and understand the inherent optical properties (IOPs) of natural particles from a standpoint of measuring size-distribution. Understand how the properties of particles (composition, shape, and internal structure) affect their IOP. Incorporate these properties into radiative transfer models for prediction of downwelling and upwelling radiances. We are developing a version of the LISST-100 forward scatter instrument that will deliver the same high-quality data in backscatter, the data will guide analytical ... |

| Under normal circumstances, a test specimen is reported as "negative" when the response of the analyte is absent. However, if the intensity of the internal standard (IS) is low, indicating interference factors, the test could be considered "inconclusive." A quantitative hypothesis, A = (RxIxS)/L, serves as the "cutoff" for the acceptable signal-to-noise (S/N) ratio for the IS in making "negative/inconclusive" decisions, where A: acceptable S/N ratio for internal standard; R: ... |

| Ongoing casualties inflicted on convoys transgressing dangerous roads highlighted airlift's important role in intratheater logistics operations within Iraq. While airlift can help decrease the number of convoys on the roads in combat zones, the finite number of airlifters must be managed effectively and efficiently to maximize its impact in supporting operations. This research proposes using a regional huband-spoke heuristic to design major-theater-war channel systems. The purpose of this research is ... |

| Colombia has been mired in internal conflict for more than four decades. The complex characteristics of Colombia's internal strife make it unique. Narco-trafficking and terrorism conducted by former communist guerrillas and right-wing paramilitary groups represent the main components of the problems facing the government and society. To deal with these complex issues, President Alvaro Uribe's administration designed a strategy known as "Democratic and Defense Policy," which showed significant results for ... |

| One of the most pressing issues in the post-conflict reconstruction field is how to prioritize and sequence political, social, and economic policies to enable post-conflict countries to sustain peace and reduce the risk of violence re-occurring. Analyzing three cases of post-conflict reconstruction (Cambodia, Mozambique, and Haiti) and expert opinions of 30 academicians and practitioners, this study identifies major reconstruction policies, outlines the preferred way to prioritize and sequence them, and ... |

| Coalition forces in Operation Iraqi Freedom (OIF) were able to take down Saddam Hussein's regime in less than three weeks, at the cost of relatively few Coalition casualties. This monograph draws upon information derived primarily from interviews with and interrogations of senior Iraqi military and civilian officials to examine why the Iraqi resistance in March and April 2003 was so weak. The research focused on two questions: (1) Why did ... |

| This paper focuses on trajectory control of the 6-DOF body fixed reference frame located on a very flexible aircraft. The 6-DOF equations of motion of a reference point on the aircraft are coupled with the aeroelastic equations that govern the geometrically nonlinear structural response of the vehicle. A low-order strain-based nonlinear structural analysis coupled with unsteady finitestate potential flow aerodynamics form the basis for the aeroelastic model. The nonlinear beam ... |

| Fixed beds of cylindrical particles are important in chemical engineering applications, but their packing structures are not as well understood or as well characterized as sphere packings. In this work, X-ray microtomography is used to obtain 3D images of 1.8 mm diameter equilateral cylinders in a 23 mm cylindrical container over a range of bulk porosities.

| It has been demonstrated, through theory and experiments, that compressive layers arrest large surface and internal cracks to produce a stress below which the material will not fail. This enables the materials to have a Threshold Strength. The stress intensity function, K, was derived for a crack sandwiched between two compressive layers. This function suggests that the threshold strength is proportional to the magnitude of the residual, compressive stress, the ... |

| Since January 2005 Pakistan's Baluchistan province has been embroiled in a rash of violence that threatens to deteriorate into civil war. Is this recent violence yet another recurrence of state-periphery tensions, or is it a qualitatively new phenomenon which threatens U. S. and Pakistan interests in the region? This thesis analyzes the historical causes of Baluch political violence in order to determine why Baluchistan is again enmeshed in bloody conflict. ... |

|
| Modem ultra high strength alloy steels (UHSS) have been developed with outstanding combinations of strength and fracture toughness. Such steels are characterized by high purity and nanoscale strengthening clusters/coherent precipitates in a complex precipitation hardened, martensitic microstructure. However, the performance of such steels is degraded dramatically by internal hydrogen embrittlement (IHE) and hydrogen environment embrittlement (HEE). Thus, the development of an UHSS that is immune to hydrogen embrittlement is of ... |

| An open system is a system whose behavior is jointly determined by its internal structure and by the input it receives from the environment. To solve control and verification problem open systems have often been modeled as games between the System and the environment; we argue that the game view of open systems should be extended also to the definitions of system refinement and composition. We give a symmetrical interpretation ... |
