Military communities in tactical networks must often maintain high group solidarity based on the trustworthiness of participating individual entities where collaboration is critical to performing team-oriented missions. Group trust is regarded as more important than trust of an individual entity since consensus among or compliance of participating entities with given protocols may significantly affect successful mission completion. This work introduces a game theoretic approach, namely Aoyagis...

Drug trafficking organizations have increased their prominence throughout the Caribbean and Central America. These organizations undermine the rule of law, increase levels of violence and corruption, and hamper development, all of which can weaken a state. Weak or failing states become domestic and regional burdens that spill over into neighboring countries and cause secondary and tertiary problems. This thesis examines causes for different state capacities in the Caribbean and Central America...

Nonlinear estimators based on the Kalman filter, the extended Kalman filter (EKF) and unscented Kalman filter (UKF) are commonly used in practical application. The Kalman filter is an optimal estimator for linear systems; the EKF and UKF are sub-optimal approximations of the Kalman filter. The EKF uses a first-order Taylor series approximation to linearize nonlinear models; the UKF uses an approximation of the states joint probability distribution. Long measurement intervals exacerbate...

Beta radioisotope energy sources, such as tritium (3H), have shown significant potential in satisfying the needs of an energy-driven world. The drawbacks of current beta source compounds include low beta-flux power, intrinsic isotope leakage, and beta self-absorption. The figure of merit for a tritiated compound is the input power or specific surface activity of the thin layer (Ci/cm2) where an optimal portion of incident beta particles are penetrating the semiconductor depletion region. The...

We present a novel fault detection method for application in component-based robotic systems. In contrast to existing work, our method specifically addresses faults in the software system of the robot using a data-driven methodology which exploits the inter-process communication of the system. This enables an application of the approach without expert knowledge or availability of complex software models. We specifically focus on performance bugs, which slowly degrade the performance of the...

This paper attempts to expand its practical significance by providing a new operational interpretation. In the context of the GrayWyner network, it is established that Wyners common information has a new lossy source coding interpretation. Specifically, it is...

Economic activity can both induce and reduce political violence. We have shown that both insurgents and government respond to rising levels of investment by increasing engagement, with violent consequences. We have explored the economic and social benefits of counterinsurgency by the Philippine military, how it can be optimally conducted, and what the effects are on both combatants and civilians.

In 2013, the Department of Defense (DOD) implemented an accuracy metric to monitor how well the services and Defense Logistics Agency were forecasting demand for inventory items. After three years, results were still poor. DOD uses a metric derived from the Mean of Absolute Percentage Error, yet it differs in significant ways, such as including unit cost to enable the aggregation of data pertaining to all items. In this study, we analyze how unit cost and other parameters affect the validity of...

Obesity, which induces low-grade inflammation, is a known risk factor for worse prognosis in many cancers including breast. We found that sphingosine-1-phosphate (S1P) produced by sphingosine kinases (SphKs) plays a critical role in obesity-related inflammation and breast cancer. Obesity increased S1P in the tumor microenvironment, as well as in the primary tumors. FTY720, a functional antagonist of S1PR1, dramatically decreased cancer progression by reducing expressions of SphK1 and S1PR1, and...

This research investigated filamentation in, and modification of, dielectric solids by multi-chromatic ultrashort laser pulses. It was a theoretical effort to develop models of multi-chromatic laser-material interactions in bulk solids and couple these to pulse propagation simulations. The research developed techniques to control filamentation and the onset of laser-induced bulk damage with multi-chromatic pulses. This included controlling modification and filamentation in solids using...

To effectively monitor human performance biomarkers, we applied electrokinetic preconcentration technique of the biomarkers onto patterned graphene-modified\ electrodes in a nanochannel by frequency-selective dielectrophoresis using the molecular dam operation. Low copy numbers of human performance biomarkers can be enriched several orders of magnitudes and detected in tens of seconds. Employing this methodology and electrochemical detection, we have demonstrated the ultrafast and...

The effort developed a comprehensive approach for determining software epistemology which significantly advances the state of the art in automated vulnerability discovery. The approach applies an analytic sieve concept and a novel hashing scheme to a large corpus of open-source software to mine information that indicates the presence of pre- and post-fix conditions in program control flow, fully exploiting the hierarchy of abstraction and richness of data produced by the artifact extraction...

Time needed to develop and field new military capabilities is becoming an increasingly serious problem. Among other things, development times have steadily increased. In this paper, we attempt to structure the schedule estimating problem, present some initial results, and propose a research agenda to improve schedule estimating. Accordingly, we seek preliminary answers to the following questions. What is the current state of the art for estimating acquisition program schedules?What should it...

Chinas meteoric rise has captured the attention of the United States. Adding to the complexity is China has successfully made inroads in Latin America. This reality has strategists and policy-makers at odds with one-another with respect to formulating a policy for addressing the growth of Chinese influence in Latin America. The concern is whether the rise of China and its increasing presence in Latin America signals a challenge to the influence of the United States in the Western Hemisphere....

Aviation operations and pilot enabling technologies are increasingly sophisticated and expensive. The result is fewer but more capable aircraft requiring highly skilled aviators. While these emerging technologies greatly improve aircraft performance and enhance mission capabilities, they require much more technologically oriented aviators to manage the systems and still fly the aircraft. The emerging gap and the weakest link is in selecting and retaining the most skilled pilots. Thus, it is...

Since 1997, DOD has been required to prepare audited financial statements. However, long-standing and pervasive financial management weaknesses have precluded DOD from being auditable. The National Defense Authorization Act (NDAA) for Fiscal Year 2010 mandated that DOD develop and maintain a plan that among other things, describes the actions needed to ensure that its consolidated financial statements are audit ready by September 30, 2017.The Senate report accompanying the NDAA for Fiscal Year...

With the goal of replacing methylene dianiline (MDA) in PMR-15 (polymerizable monomeric reactant), which is a known toxin to humans, a thermally stable, polyhedral oligomeric silsequioxane (POSS) dianiline, which features an aromatic periphery, was copolymerized as a drop-in replacement. The chain length of the experimental oligomers was varied to study effects of cross-link density and nadic endcap concentration. The resultant oligomers were characterized for various neat resin and composite...

PEO GCS requested AMSAA to conduct a verification and validation (V and V) of the Whole System Trade Analysis Tool (WSTAT). In the early stages of the V and V for development risk, it was discovered that the original risk rating and methodology did not actually represent development risk, because consequences were not considered (only likelihood). As a result, an appropriate development risk methodology needed to be created for the intended WSTAT applications. In addition to incorporating...

U.S. sanctionsand U.S. attempts to impose multilateral and international sanctionshave been a significant component of U.S. Iran policy since the 1979 revolution. The objectives of U.S. sanctions have evolved over time. In the 1980s and 1990s, U.S. sanctions were intended to try to compel Iran to cease supporting acts of terrorism and to limit Irans strategic power in the Middle East more generally. Since the mid-2000s, U.S. sanctions have focused on ensuring that Irans nuclear program is for...

Adequately capturing lessons learned from noncombatant evacuation operations is crucial to improving this inherently joint and interagency effort. As the lead federal agency for the evacuation of U.S. citizens from areas of natural disaster, civil unrest, or other large scale emergency situations, the Department of State should also take the lead in conducting after action reviews and capturing lessons learned following NEOs. This work seeks to determine the current processes and capabilities...
