The U.S. Army s Surface Deployment and Distribution Command (SDDC) asked RAND Arroyo Center to assess the mechanisms by which SDDC funds its two ammunition ports, Military Ocean Terminal Concord (MOTCO) and Military Ocean Terminal Sunny Point (MOTSU). With a legacy of different histories, the two ports currently have different funding approaches and accounting systems. With both now managed by SDDC, consolidation to a single approach would seem desirable. The central question of this research...

Biological samples from victims of aircraft accidents are analyzed for carboxyhemoglobin (COHb) and cyanide ion (CN-) in blood. Such victims quite often suffer large open wounds near the autopsy blood collection sites. Many aircraft crashes result in fires that fill the victim's atmosphere with smoke rich in carbon monoxide (CO) and hydrogen cyanide (HCN). It is important to determine whether pooled blood in those open wounds may have absorbed CO and HCN after death, which could lead one to...

It is shown that liquid B2O3 does not wet B and a clear phase separation was noted in the Knudsen cell. This problem was solved by using FeB and Fe2B to supply a different and constant activity of B. The thermodynamic data thus derived are compared to quantum chemical composite calculations. A major...

We compare horizontal flow fields in the photosphere and in the subphotosphere (a layer 0.5 megameters below the photosphere) in two solar active regions: AR11084 and AR11158. AR11084 is a mature, simple active region without significant flaring activity, and AR11158 is a multipolar, complex active region with magnetic flux emerging during the period studied. Flows in the photosphere are derived by applying the Differential Affine Velocity Estimator for Vector Magnetograms (DAVE4VM) on...

Maintaining an accurate common operating picture (COP) is a strategic requirement for efficient and successful missions in both disaster response and battlefield scenarios. Past practices include utilizing cellular, radio, and computer based communication methods and updating individual maps. A drawback of these practices has been interoperability of these devices as well as inaccurate reporting and documentation among different entities of the effort. Recent advances in technology have led to...

Craig (2001) hypothesized a killing zone--a range of pilot total flight hours (TFH) from about 50-350, over which general aviation (GA) pilots are at greatest risk. The current work tested a number of candidate modeling functions on eight samples of National Transportation Safety Board GA accident data encompassing the years 1983-2011. The goal was largely atheoretical, being merely to show that such data can be modeled. While log-normal and Weibull probability density functions (pdf) appeared...

During this period of performance, we processed data collected in different node location configurations for accuracy of the currently implemented algorithm, which is an edge detection algorithm. It sets the base line performance of the current ranging system. In the next reporting periods, we will reprocess this data to show the improvement achievable by digital beam forming. Figure 1 shows the correlation between the actual measured range between the master and the slave and the reported...

We confirmed that polarization modulation is a viable technique for high repetition radar, particularly pulsed terahertz radar, through the use of a scaled experiment. We believe that our pulsing hardware, combined with a focusing dish, would prove a powerful standoff imaging solution. Though we encountered multiple fabrication issues that delayed the completion of a prototype system, we hope to have a working prototype by the second quarter of 2012.

The recent availability of midwave-IR semiconductor lasers capable of emitting narrow spectral lines at ambient or thermoelectric-cooler temperatures (above -20 deg C) has spawned the development of a new generation of chemical sensing systems designed to exploit the prevalence of strong mid-IR spectroscopic signatures. Although the required laser output powers tend to be rather modest (less than or equal 1mW), minimizing the drive power can be critical because the most attractive systems will...

The importance of innate immune cells in HIV-1 pathogenesis and protection has been highlighted by the role of natural killer (NK) cells in the containment of viral replication. Use of peripheral blood mononuclear cells (PBMC) in immunologic studies provides both HIV-1 target cells (ie. CD4+ T cells), as well as anti-HIV-1 effector cells, such as NK cells. In this study, NK and other immune cell populations were analyzed in HIV-negative donor PBMC for an impact on the anti-HIV activity of...

The objective of this grant is to improve understanding of how the large-amplitude internal waves and tides in the northeastern South China Sea are generated via interaction of the barotropic tide with the ridges and islands in the Luzon Strait. In addition to the problem s inherent scientific interest, understanding the generation problem is essential for developing a forecast model to predict the wave characteristics in the deep basin and on the Chinese continental slope and shelf.

We study the maximum temperature rise induced by a rotating or dithering Gaussian laser beam on a two-layer body. First, we derive semi-analytical solutions by solving the transient three- dimensional heat equation in a semi-infinite domain with insulating surface. Second, we provide numerical solutions for a two-layer structure in a finite domain. Our results show that the maximum temperature rise can be reduced significantly either by applying a thin layer of coating on the protected object...

Ocean salinity is one of the most important variables in oceanic and climate studies. Together with temperature they regulate the density of ocean water and are used to determine the formation of water masses and circulation. Whereas temperature has been measured very extensively in the world s oceans by both in-situ and remote means, salinity observations are very limited and not uniformly distributed geographically; they are mainly confined to shipping lanes and the summer season....

In this paper, we consider the evaluation of information divergence and information gain as they apply to a hybrid random variable (i.e. a random variable which has both discrete and continuous elements) for multi-target tracking problems. In particular, we develop a closed-form solution for the Cauchy- Schwarz information divergence under the assumption that the continuous element of the random variable may be represented by a Gaussian mixture distribution and present the associated...

This report describes work carried out on numerical modeling of flow control devices based on pulsed electrical discharges. Given the lack of flow control options in the high-speed regime, there is strong interest in developing such devices for control of laminar-turbulent transition, turbulence, engine unstart, and inlet shock train stability. Pulsed electrical discharge actuators offer the features of rapid actuation, low profile, and low mean power consumption. Under this project, work was...

America has long been known as a great melting pot in which people of various ethnic heritages and cultures have melted into a common American culture and national identity. We derive our national interests from our national identity. Our national interests are manifested in our national political ideology, national policies, and in our National Security Strategy. We sustain the continuity of our national political ideology and our national interests by refreshing our society with the...

This thesis asks the questions: Are our maritime organizations organized and employed properly to ensure our nation's maritime security? Should maritime law enforcement be considered a critical capability for the Navy? Maritime security is not only a priority mission in the national and naval strategy, but for the international maritime community as well. It is established that law enforcement presents the best means to achieve maritime security. By accepting the maritime law enforcement role,...

Federal administration of this nation's emergency medical services (EMS) has come under increasing criticism, in a post- September 11 world, by many of its stakeholders and constituents. Critics accurately argue that the current construct of federal governance and oversight is impairing the discipline's shareholders from being able to prepare, train, respond and recover appropriately from natural and manmade catastrophic events both locally and nationally. Valid reasons exist to endorse...

Liquid resins used for molding composite structures are a significant source of hazardous air pollutant (HAP) emissions. One method of reducing styrene emissions from vinyl ester (VE) resins is to replace some or all of the styrene with fatty acid based monomers. This patented technology allows for the formulation of high-performance composite resins with no more than 25 weight-percent styrene, which is a 25% 50% reduction in HAP emissions vs. commercial VE resins. This work validated the...

Throughout history, small nation-states have generally organized their militaries and based their homeland-defense strategies on at least one of four conventional models. They have from time to time chosen to imitate large states militaries, have joined alliances, assumed neutrality, obtained weapons of mass destruction in more modern times, or implemented some combination of these. A deeper analysis of history, however, unearths other possibilities for defensive postures. The use of irregular...

This purpose of this project is to review and analyze the changes that have been made in the Federal Acquisition Regulation (FAR) over the past few years to place a preference on the award of multiple contracts in the case of an Indefinite Delivery Indefinite Quantity (IDIQ) contract. An IDIQ contract is initially awarded as a base contract that establishes the scope of services or goods that can be ordered against it. The base contract has no funding associated with it and merely lays out the...

The utility of commercially available chemical dosimeter badges to adequately sample low-concentration formaldehyde vapor aboard Navy submarines was evaluated. In this work, badges were exposed to formaldehyde vapor at two approximate concentrations: 6 ppb and 2.5 ppb (13% and 6% of the Navy 90-day exposure limit, respectively) and for durations of 30, 60, 90, and 120 hours. Certified permeation tubes were used to generate formaldehyde vapor, which was then validated by a reference method...

The first year of our funding has been very productive and has led to new information regarding susceptibility of Malignant peripheral nerve sheath tumors (MPNST), which occur in patients with neurofibromatosis type-1, to oncolytic HSV (oHSVs). We have demonstrated that many of the MPNSTs that have tested are indeed sensitive to our oHSV, but that some are resistant (both murine and human). It is apparent from our data that ability to replicate in these tumor cells is related to additional...

In this paper we investigate the mechanical behavior of carbon fiber composites, where the carbon fibers are coated with radially aligned carbon nanotubes. For this purpose we develop a general micromechanics method for fiber composites, where fibers are coated with radially aligned microfibers ( fuzzy fiber composites). The mechanical effective properties are computed with a special extension of the composite cylinders method. The in-plane shear modulus is determined using an extended version...

To remain the force of choice against future threats, the Marine Corps must increase its irregular warfare capabilities. Key to this is developing a group of foreign security force advisors who can provide persistent engagement in trouble areas to prevent future conflicts. Currently the Marine Corps builds advisor teams in an ad hoc manner, paying little attention to the unique skills required for advisory duty. To prepare Marine foreign security force advisors the Marine Corps must apply...

Is it time for Ohio to take bolder steps toward turning around its most troubled schools and districts? If so, what might the alternatives look like? Options for rebooting these troubled schools have come in the form of mayoral control, state takeovers, market competition through charter schools and other choice programs, as well as millions of federal dollars spent on "school turnaround", yet it seems that it might be time to try something new in Ohio. In looking for alternatives to...

The history of higher education has revealed all the forms of structural change associated with growth. The following focuses on a special form that involves growth, specialization, and proliferation, and applies mainly but not exclusively to universities. In search for a descriptive term, I have settled on the concept of "structural accretion," a composite form of growth. Its simple definition is incorporation of new functions over time without, however, shedding existing ones or...
