Camera-based measurement of the blood volume pulse via non-contact, imaging photoplethysmography is a very popular approach for measuring pulse rate using a remote imaging sensor. Comparatively less attention has been paid to the usefulness of the method for measuring features of pulse rate variability, and even less focus has been put on the accuracy of any cardiac activity feature that can be achieved at long imager-to-subject distances. In this study, video was recorded from 19 participants,...

Current Navy plans call for achieving and maintaining a fleet of 308 ships of certain types and numbers. Some observers have advocated increasing the Navys force-level goal to about 350 ships. The Navy is currently conducting a force structure assessment (FSA), and some observers anticipate that this FSA will lead to a new Navy force-level goal of more than 308 ships, although not necessarily 350 ships. The Navys actual size in recent years has generally been in the range of 270 to 290 ships....

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...

While Moore's Law theoretically doubles processor performance every 24 months, much of the realizable performance remains untapped because the burden falls to the (less informed) domain scientist or engineer to exploit parallel hardware for performance gains. Even when such untapped hardware potential is fully realized, it is often not coupled with advances in algorithmic innovation, which can deliver further (multiplicative) speed-up beyond Moore's Law, as noted in the AFOSR BAA. In this...

This standard process description (SPD) provides the instructions needed in qualifying candidate adhesives for the screening tests specified in ARL-ADHES-QA-001.00, Sections 8.2 and 8.3. The single-lap-joint testing configuration relies upon a relatively small bond area between adherends, which can lead to high standard deviations in measured strengths. Geometrical misalignment and variations in bondline thickness are potential sources of inaccurate property measurements. Poor surface treatment...

Sepsis is associated with a mortality of nearly 30%. Mortality is due, in part, to an uncontrolled inflammatory response. Matrix metalloproteinase-9 (MMP-9) and heat shock protein 70 (HSP 70) have been suggested to be biomarkers of severe sepsis and may be useful indicators of treatment success. Hydroxocobalamin (HOC), which regulates inducible nitric oxide synthase and increases systemic vascular resistance, may be effective in treating sepsis-induced hypotension and reversing overexpression...

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...

The purpose of this paper is to explain briefly the use of a certain equation which will allow us to compute the velocity Vm when the dimensions of the inlet and its bay, together with the tidal range of the outside sea, are known. No attempt will be made to derive the equation other than to point out that it is obtained by eliminating a single variable between two equations which have been previously derived by Colonel Earl I. Brown in a paper entitled Inlets on Sandy Coasts in the Proceedings...

In 2014, the armed offensive of the Islamic State (also known as ISIL, ISIS, or Daesh) in northern and western Iraq and northeastern Syria raised significant concerns for the United States. After first ordering multiple deployments of U.S. troops to Iraq to provide security to diplomatic personnel and facilities, advise Iraqi security forces, and conduct intelligence gathering and reconnaissance, President Obama began ordering U.S. military airstrikes on IS forces in Iraq in August 2014. Later...

Prior research has investigated partially ventilated steady transom flows for a family of hulls that have a common fore-body with varying after-bodies. This project expands the investigation into unsteady transom flow elevations two of the five different transom configurations, including a round bilge and a deep-vee sections. A common wave profile was used for the experiments and wave elevations were measured at 24 different positions within the towing tank.. High definition video was used to...

This paper explores the possibility of using multiplicative gate to build two recurrent neural network structures. These two structures are called Deep Simple Gated Unit (DSGU) and Simple Gated Unit (SGU), which are structures for learning long-term dependencies. Compared to traditional Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), both structures require fewer parameters and less computation time in sequence classification tasks. Unlike GRU and LSTM, which require more than one...

In this paper, we introduce a new networking architecture called Group Centric Networking (GCN) that is designed to support the large number of devices expected with the emergence of the Internet of Things. GCN is designed to enable these devices to operate collaboratively in a highly efficient and resilient fashion, while not sacrificing the users? ability to communicate with one another. We do a full protocol implementation of GCN in NS3, and verify GCN in emulation and on real hardware...

We are examining the hypothesis that mitochondrial inheritance plays a significant role in aggressiveness of prostate cancer in African Americans. In the first year of the project we identified 2,000 noncancerous tissues samples from African American men with prostate cancer and we have extracted DNA from 1,500 of them. We have validated a robust new DNA sequencing technique developed by our collaborator using single amplicon long-range PCR that permits deep coverage (10,000-20,000X on average)...

We have unified the finite Set Statistics (FISST) and Multi-Hypothesis Tracking (MHT) methodologies for multi-target tracking and developed a randomized version of FISST called RFISST that makes the implementation of the full FISST/MHT recursions computationally tractable. The DDDAS paradigm used in this method actively controls the number of likely hypotheses, pruning them based on data coming from the sensors. We developed particle-based Gaussian Mixture Filters that are immune to the curse...

The ultimate goal of this project was to develop a model of a flight control strategy that is effective in simple as well as complex environments. Through a series of behavioural and anatomical investigations, we have made much progress in elucidating the flight control strategies and visual specialisations that allow insects, with their miniature brains and limited sensory systems to fly safely through cluttered natural environments. The most significant findings have been that the tropical...

Deep convolutional neural networks (CNNs) detect and classify features of interest in sensory input data. There is a need to investigate how best to implement CNNs for Navy and Department of Defense (DoD) use in platforms with minimal size, weight, and power (SWaP) capacity, since much academic research focuses solely on achieving the highest performance on a specific dataset with minimal concern of compute resources. This report describes a methodology, configuration, and experimental results...

The Greenland Inland Traverse (GrIT) transports fuel and cargo over snow to resupply science stations on the Greenland ice sheet from Thule Air Base. GrIT offers an alternative to the traditional LC-130 airlift resupply from Kangerlussuaq, Greenland. In this report, we assess the economics of GrIT relative to airlift resupply operations by comparing the costs of each mode to deliver the same fuel and cargo based on data from the 2012 and 2014 seasons.

The goal of this research is to increase our understanding of the impact of the ocean and seafloor environmental variability on deep-water (long-range) ocean acoustic propagation and to develop methodologies for including this in acoustic models. Experimental analysis is combined with model development to isolate specific physics and improve our understanding. During the past few years, the physics effects studied have been three-dimensional propagation on global scales, deep water ambient...
