This Phase I proposal describes the development of an Automatic Threat Recognition (ATR) algorithm for volumetric CT data. Our ATR algorithm consists of four stages: (1) preprocessing of CT data, (2) object segmentation of preprocessed CT data, (3) post-processing of segmentation results, and (4) explosive detection from the segmented objects. The ATR algorithm will be made computationally efficie ...

This Phase I proposal describes (1) an automated image quality assessment (IQA) software to objectively quantify image quality of airport security X-ray imaging systems for both checked and carry-on baggage and (2) a design for a novel test phantom specialized for security CT scanners. For fixed images, automated algorithms will measure the Modulation Transfer Function (MTF) and Contrast-to-Noise ...

The DOD has a need to leverage state of the art technologies remotely detect, collect, and evaluate physiological signals of interest. Applications and concepts-of-operations (CONOPs) that would benefit from this capability include, but are not limited to: building-clearing, warfighter health monitoring or battle damage assessment and triage, situational awareness and assessment. The main goal o ...

Our Precision ACS (PACS) while combined with either a Liquid or Solid DACS delivers high precision Kinetic Weapon (KW) attitude control for long range target discrimination and acquisition. The PACS features multiple pulse Electric Solid Propellant (ESP) thrusters that are either individually pulsed controlled for very small impulse BIT"s or controlled in parallel for larger ACS thrust. The PACS ...

ABSTRACT: Carbon dioxide feed stock can be converted into fuels of solid, liquid or gas phase by chemical, electrolytic, photocatalytic and photo-electrocatalytic methods. Reduction of CO2 to fuel form of any phase requires energy. The reduction process should be energy efficient so that we do not spend more energy and emit more (indirect) CO2 in the process of converting CO2. From this point of ...

An estimated 20% of a US Navy ship"s total fuel consumption is due to heating, ventilation and air-conditioning. Reduction in electrical consumption of Navy ship Fan Coil Assemblies with increased energy efficiency is necessary for fuel savings. Rocky Research proposes an advanced Fan Coil Assembly Unit with high efficiency heat exchangers, low-noise fan design, variable speed drive technology and ...

ABSTRACT: Thermal energy storage for load smoothing can be beneficial in applications having large transient heat load compared to steady-state heat rejection. Laser weapons and high-power microwave generators are examples where TES can help. Ammoniated complex compound systems can provide heat absorption due to exothermic dissociation of the complex compound. Very high energy density and powe ...

The principal objective of this effort is to develop an advanced complex compound for ammonia-solid absorption chillers and demonstrate the enhanced sorbent for a 18,000 BTU/hr technology demonstrator in the Phase II effort. Phase I experimental data showed that it is feasible to make a fuel-fired sorption cooling system capable of 18,000 Btu/hr cooling and 105 kg dry-weight with 0.34 gal/hr of JP ...

We will use our newly developed smart energetic materials to eliminate flame sensitive pyrogens and the bridge-wire connections for thermal ignition within initiators/squibs which will improve safety for Mil. Std. 1901A compliance. Unlike conventional materials, new pyrogen materials are insensitive to ignition by flame and so can not flame spread by impingement. However, new faster burning formu ...

The objective of this research is to enable pre-process milling parameter selection for"first part correct"production. In the proposed solution the Receptance Coupling Substructure Analysis (RCSA) approach will be used to couple the measured spindle-machine dynamics to models of the tool and holder and predict the assembly"s dynamic response. Given this information, frequency/time-domain algorithm ...
