| Weak, failing, failed and post-conflict states pose one of the greatest national and international security challenges of our day. The stabilization and development of faltering states is in both the short- and long-term interests of the United States because stable states pose fewer security challenges. Afghanistan is a failed state that presents security challenges on a global scale as well as a classic case study on insurgency that needs a ... |

|
| Recently, Gravity Gradient Instruments (GGIs) - devices which measure the spatial derivatives of gravity, have improved remarkably due to development of accelerometer technologies. Specialized GGIs are currently flown on aircraft for geological purposes in the mining industries. As such, gravity gradient data is recorded in flight and detailed gradient maps are created after post mission processing. These maps, if stored in a database onboard an aircraft and combined with a ... |

| Senior military commanders are hindering tactical-level operations in Iraq and Afghanistan. According to the Marine Corps Warfighting Publication on counterinsurgency operations, counterinsurgency operations are best conducted in a decentralized command structure with an emphasis on initiative and adaptation at the tactical level. However, at this time, several strategic- and operational-level commanders are restricting decentralized decision-making by mandating maximum levels of body armor employment to their tactical-level subordinates. Centralized decisions mandating ... |

| The optimal sensor placement problem, as considered here, is to select the types and locations of sensors providing coverage at high value terrain locations while minimizing a specified cost function. The cost function can reflect various disincentives, such as the actual cost of the sensors, the total number of sensors, and the probability that the sensor will be found and disabled by hostile actors. The probability of detection (at a ... |

| A major challenge of remote infrastructure classification is to distinguish pavements from roofs. We proposed that, due to their differing thermal masses, these elements will heat and cool differently. Therefore, their thermal infrared (IR) signatures will differ throughout a 24-hour cycle. We propose a method to rapidly identify urban infrastructure that will assist the Future Force in dominating the urban battlespace to the same degree that the current force dominates ... |

| The base zone in combat operations refers to an area that is secured against intrusion and attacks from insurgents. During any type of military operation, the number of sensor assets that are available for detecting intrusions are limited. Thus, the size of a base zone is limited by the number of available sensors, and how those sensors are deployed. Depending on the assumptions made in modeling the coverage properties and ... |

| Eigenanalysis of temperature and wind profiles can reveal distinct resonances at mesoscale wavelengths. Fourier transform methods are well suited to analyze resonant modes such as mountain waves due, in part, to (1) their fast computation speed for large wave number domains compared to numerical forecast models and (2) their requirements for only a coarse horizontal background state. Common traits of Fourier mountain wave models include use of the Boussinesq approximation ... |
