Defense Technical Information Archive

The Defense Technical Information Center (DTIC) is the premier repository for research and engineering information for the United States Department of Defense. DTIC's Suite of Services is available to DoD personnel, defense contractors, federal government personnel and contractors and selected academic institutions. The general public can access unclassified, unlimited information, including many full-text downloadable documents, through the public Web site, DTIC Online.

DTIC's collections contain over 4 million documents including technical reports, research in progress and Independent Research and Development (IR&D) summaries. DTIC also publishes searchable Congressional budget data shortly after its release from Congress. DTIC acquires approximately 25,000 new documents each year.

On June 4, 2004, DTIC became a DoD Field Activity under the management of the Under Secretary of Defense for Acquisition, Technology, and Logistics, reporting to the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)). Mr. Christopher Thomas is the Administrator.

DTIC's mission statement is "To provide essential, technical research, development, testing and evaluation (RDT&E) information rapidly, accurately and reliably to support our DoD customers' needs."

The ability to precisely determine the location of radar transmitters can be crucially important in maintaining domain awareness. This, however, may be problematic with traditional methods when used with a distributed network of disparate sensors. A novel geolocation technique for circularly scanning radar transmitters is introduced. This technique uses the differenced central times of arrival (DCTOA) of the mainbeam as an observable. The solution for the transmitters position and scan rate are...

Civil-military relations describe the interactions among the people of a state, the institutions of that state, and the military of the state. At the institutional level, there are two hands on the sword.1 The civil hand determines when to draw it from the scabbard and thence guides it in its use. This is the dominant hand of policy, the purpose for which the sword exists in the first place. The military's hand sharpens the sword for use and wields it in combat.

The Germans invented and developed the modern war game. By the end of the nineteenth century, the German-style Kriegsspiel had been adopted in most of the major militaries of the day. In the interwar years (191939), the Germans greatly increased the number and diversity of war games, which collectively became one of the main means of educating and training future commanders and their staffs at all levels. Prior to and during World War II, the Germans proved to be masters of the use of war games...

Command of the sea denotes a strategic condition, and it is from this actual condition that the logic flows, whatever words are used to describe it. Since ancient times, navies have sought to control communications on the sea. Such control might be generalsuch as the Romans and British achieved at various timesor it might be local and temporary. In either case the object of such control has been to protect ones own commerce, disrupt the enemys, move one's own army, and prevent the movement of...

An optically pumped edge-emitting semiconductor laser emitting near 4.1 m was designed with weak transverse mode confinement resulting in an exceptionally large transverse optical mode size. Consequently, a laser device is reported that exhibits a fast-axis divergence angle of 4.2 full-width at half-maximum (FWHM). More notably, a large reduction of the lateral axis divergence is also observed as a result of the increased lateral coherency. The reduced confinement factor and differential gain...

It is well-known that stand-alone inertial navigation systems (INS) have their errors diverging with time. The traditional approach for solving such incovenience is to resort to position and velocity aiding such as global navigation satellite systems (GNSS) signals. However, misalignment errors in such fusion architecture are not observable in the absence of maneuvers.

For the first part of the study, an in vitro 3 dimensional (3D) model of primary human osteoblasts in a collagen scaffold was developed for infection. The 3D osteoblast cultures were infected with clinical isolates of multidrug resistant Acinetobacter baumannii, Klebsiella pneumoniae and...

Microbial colonization is thought to play a critical role in the healing trajectory of wounds. The microbial load and community composition are both important variables that, historically, were extremely difficult to characterize. Under this award, we have developed a suite of cutting-edge molecular tools, databases, and analytical approaches to enable more accurate characterization of wound microbiota. In the past year, we developed and validated culture-independent molecular tools for...

The last decade has witnessed an exponential growth in terrorism and violence emanating from transnational terrorist organizations and insurgencies. Even though the 'second grammar' of warfare - COIN operations, has existed for ages, this rise in terror has led to a global revisit on COIN. In the light of this renewed focus on COIN, this monograph analyses the experience of the Indian Army in COIN operations. In spite of a six-decade long history of COIN campaigns, these Indian COIN campaigns...

Previously, Chang reported a new high-order Conservation Element Solution Element (CESE) method for solving nonlinear, scalar, hyperbolic partial differential equations in one dimensional space. Bilyeu et al. have extended Changs scheme for solving a one dimensional, coupled equations with an arbitrary order of accuracy. In the present paper, the one-dimensional, high-order CESE method is extended for two-dimensional unstructured meshes. A formulation is presented for solving the coupled...

A system with unequal populations of up and down fermions may exhibit a LarkinOvchinnikov (LO) phase characterized by periodic domain walls across which the order parameter changes sign and the excess polarization is localized. Despite fifty years of theoretical and experimental work, there has so far been no unambiguous observation of an LO phase. Here we propose an experiment in which two fermion clouds, prepared with unequal population imbalances, are allowed to expand and interfere. We show...

This study has rested on two basic hypotheses. The first is that agents given during and (for a short period of time) after resuscitation can favorably influence the response to hemorrhagic shock and injury. The second is that studies of gene response studies, specifically microarray and RT-PCR studies, could be used to assess the response of patients being treated for injuries to such therapeutic agents. To date, both hypotheses have been shown to be true in the animal model. Three therapeutic...

As more adults are seeking orthodontic treatment, patients with gold or porcelain restorations are seeking orthodontic care. Traditional methods of bonding to these restorations require some type of surface modification. DentStat is a compomer that was developed as temporary material for military use in a field environment. There are claims made that it can adhere to any surface. This study attempts to determine if DentStat can be used as a bracket adhesive that does not require surface...

We believe that Readiness Based Sparing (RBS) is the superior method of sparing, far more efficient, cost-effective, and comprehensive than its predecessors, and that it should be utilized across the U.S. Department of Defense. Unfortunately, Department of Defense and Air Force policy is currently rather ambiguous concerning its use, and we plan to make a case to those individuals involved in policy-making to update the wording of such policy to more plainly mandate the use of RBS methods. In...

Introduction. Evidence suggests that social support and stress may play important roles in the development and progression of heart failure, an end stage of cardiovascular disease (Mookadam and Arthur, 2004; Murberg and Bru, 2001). Cohen and Wills (1985) posit that social support may influence disease through direct effects and by buffering the impact of stress on health. The present study examined (1) the main effect of functional and structural social support, independently, on markers of...

American children are becoming increasingly overweight. The prevalence of childhood obesity has tripled in recent decades. Obesity during childhood places youth at high risk for poor health outcomes as adults. Factors associated with the prenatal and early infant enviromnent are some of the earliest predictors of excessive weight gain in children that have been studied. Both excess and insufficient maternal prenatal weight gain have been associated with adverse cardiometabolic outcomes in late...

With the growing numbers of traumatic brain injuries (TBIs) occurring within the OIF/OEF combat theaters of operations, there is a greater need to identify clinical correlates of post-concussive symptoms (PCSx) within Veterans with a history of TBI. A retrospective record review was conducted within a group of OEF/OIF Veterans with TBI who completed a neuropsychological assessment. Differences in PCSx were examined by injury severity, number of TBIs sustained, and time since injury....

Current wars are taking physical and psychological tolls on American service members. Many Warriors return with traumatic brain injuries (TBI) and mental health problems. Psychological stress that Warriors experience might contribute to the TBI-mental health problem relationship. This experiment examined blast injury and psychological stress in male and female rats. A blast over pressure paradigm (BOP) was used to model blast exposure. A combination of predator and environmental stressors was...

During orthodontic treatment, photographs or radiographs of patients are typically utilized to evaluate soft tissue growth and treatment change. As a means of assessing these changes, direct superimposition of images taken at different time points is traditionally accomplished. This study was accomplished in order to determine the reliability of using True Sagittal, Coronal and Frontal reference planes for image superimposition, based on a patients Natural Head Position (NHP). The study was...

The CD4 T helper cells play a central role in initiating immune responses to various types of infections that have breached the immune defense. In the context of vaccination, CD4 T-cells are critical for establishing broad, long-lasting protective immunity. It is known that T-regulatory cells (T-regs) can limit CD4 T-cell responses during influenza viral infection, however less is known about the effect of T-regs in influenza vaccination. In this dissertation, I first present evidence that the...

The transverse dimension of the craniofacial complex has long been suspected of following the deficiencies and excesses of the anteroposterior (AP) dimension. While the AP and even vertical dimensions of the maxilla and mandible have for years been easily assessed with the lateral cephalogram, the relative lack of posterior/anterior (PA) cephs in routine clinical use and a paucity of transverse analyses have made evaluation of the width of the mandible more subjective than the other dimensions....
