The research reported here details a fundamental investigation of two modified germanate based glasses with a specific focus on glass stability during thermal-cycling which is representative of the steps required to fabricate a doped micro-structured germanate fiber. The investigations revealed for germanate fibres, surface crystallisation is the dominant loss mechanism, and may explain the poor performance of all published germanate fiber lasers. The research team have found a composition of...

Today's infrastructure as a service (IaaS) cloud environments rely upon full trust in the provider to secure applications and data. Cloud providers do not offer the ability to create hardware-rooted cryptographic identities for IaaS cloud resources or sucient information to verify the integrity of systems. Trusted computing protocols and hardware like the TPM have long promised a solution to this problem. However, these technologies have not seen broad adoption because of their complexity of...

In Year 2 of this award we examined whether duraplasty after acute thoracic spinal cord injury (SCI) in a porcine model could improve long-term functional outcome after injury. We finalized the 12-week PTIBS analysis as well as the somatosensory-evoked potential, which was recorded at baseline, 3 hours post injury and at the final week of the study (12 weeks post SCI). Our data suggest that duraplasty surgery might improve functional recovery early after SCI compared to SCI-animals without...

No military officer can escape the fact that he or she is a leader. With this charge comes the great responsibility of power. Failure to understand the psychology of this power and use it judiciously deteriorates the trust in the leader/follower relationship. Degraded trust can have lasting impacts on this relationship which can cut deeply enough to negatively impact the mission. It is with this basic premise in mind that this paper provides a brief review of the Air Forces use of their...

USFOR-A was unable to achieve its goal of training the ANAs NEB to a partially capable level by December 31, 2014. The inability to achieve this goal was largely due to delays in basic soldier training and providing engineer equipment needed for training. To track the training progress, USFOR-A rated the NEBs capability on a monthly basis. USFOR-A assessments for the period April 2014 through October 2014 showed that the NEB was rated overall as developing, the second lowest of five possible...

Problems of this type are well studied [18] and usually are carried out under an assumption that u belongs to a prescribed model class, typically a known compact subset of H. Motivated by reduced modeling for solving parametric partial differential equations, this paper considers another setting where the...

The balance operator and its adjoint for the Navy Coastal Ocean Model (NCOM) have been coded. The operator is implemented in two modes: (a) with and (b) without the integral continuity constraint. Testing the code in an Adriatic Sea configuration has shown that although the a-mode option is several times more computationally expensive, it provides half the ageostrophic motions excited by perturbations with a typical horizontal scale of the internal Rossby radius of deformation.

This thesis provides a theoretical foundation for space warfare, develops a space theory based on irregular warfare principles, and applies the theory towards a US space strategy. Space warfare is a subset to general war theory because space actions are merely political extensions and can be violent. An irregular space warfare theory's primary purpose is to ensure survivable space-derived services.

In separate, replicated experiments, we experimentally established wash-off coefficients (kw) for the chemical agent VX on grass, utilizing 1 and 3 L VX droplets at 0.017 (1 min), 1, and 4 h after dissemination. A 10 mm (0.39 in.) rain event at 0.017 h after dissemination washed off 95 and 83% of the 1 and 3 L VX droplets, respectively. At 1 h after dissemination, a 10 mm rain event washed off 0.03 and 0.5% of the 1 and 3 L VX droplets, respectively. At 0.017 h after dissemination, the kw...

A thermal bimorph is a thin laminate which develops curvature upon heating on account of being constructed from layers of mismatched thermal expansion coefficients. However, current bimorphs are generally limited to benign temperatures and linear temperature displacement relationships. This work develops modelling techniques and fabrication methods that facilitate the use of nonlinear-response thermal bimorphs in high-temperature morphing structures. Successful application of this work may...

On the surface, the majority of Air Force units appear to be executing some form of project risk management (PRM). Deeper investigation exposes many of the PRM practices currently in place to often be ad hoc, and as such, have the potential to poorly inform decisions when risk data is escalated to the enterprise levels of the Air Force. Resultantly, there is inconsistency between the PRM processes practiced by Air Force units. This inconsistency is an indication of risk mishandling at the...

A series of organizational changes within the Office of the Secretary of Defense (OSD) since the Cold Wars end arguably fostered a devolution of focus on the nuclear enterprise. This culminated with inexcusable incidents that questioned the credibility of the United States nuclear enterprise. Through a content analysis of reports, directives, and historical documents with interviews of Department of Defense (DoD) personnel, this research found that the organizational changes drove a dissolution...

Network knowledge synthesis (NKS) refers to effective use of network defense information for cyber assessment and management. The vision of NKS is to achieve better informed situational awareness leading to superior cyber defense. Five major components are necessary to achieve this vision: sensor placement, data collection, data filtering, data analysis and sense making, and information sharing. By reviewing the state of the art for each of these components, we identify high-priority,...

DOD is the governments largest purchaser of contractor-provided services. In 2008, Congress required DOD to compile and review an annual inventory of its contracted services to identify the number of contractors performing services and the functions contractors performed. In 2011, Congress required DOD to use that inventory to inform certain decision-making processes, including workforce planning and budgeting. GAO has previously reported on the challenges DOD faces in compiling, reviewing, and...
