To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

Sentient Corporation proposes to integrate its DigitalClone Component (DCC) physics-based modeling technology and Johns Hopkins University Applied Physics Laboratorys in-situ thermal sensors to develop a comprehensive sensor-based tool to monitor, identify and locate defects in metallic additive manufacturing, and create a DCC model-enabled feedback loop to correct the process-induced defects to i ...

To reduce size, weight, power and cost (SWaP-c), military platforms have been evolving towards more integrated platforms that utilize all available space. For radiating systems, this will require exploring innovative design methods, materials and manufacturing approaches to realize cost-effective, customizable and conformal antennas. An attractive solution to this challenge is offered by additive ...

This project aims to develop a low-cost millimeter-wave (mmW) imaging system for ground vehicles, to operate in combination with a long-wave infrared (LWIR) camera. Such a system will mitigate the challenges of driving in degraded visual environments (DVE) including night time, fog, dust, or smoke by providing real-time image of the vehicle surrounding independent from the presence of naturally oc ...

Modern computer systems often incorporate multiple computational devices such as conventional processors, graphics processing units (GPUs), specialized accelerators, and field-programmable gate arrays (FPGAs). Programmers are able to exploit these new architectures for improved performance and reduced power consumption, but at the cost of increased programing complexity. Further complicating matte ...

To reduce size, weight, power and cost (SWaP-c) military platforms have been evolving towards a more integrated design approach that efficiently utilizes all available space.To accommodate limited space constraints many commercial off-the-shelf (COTS) systems will need to be replaced by custom designed and fabricated components.For the case of radiofrequency (RF) electronic systems this will requi ...

A bore evacuator is generally used in gun barrel of armored fighting vehicles to help prevent poisonous propellant gases from venting back into the fighting compartment. It consists of a ring of holes drilled into the barrel, surrounded by a cylindrical pressure reservoir. Under typical operating conditions, pitting corrosions and stress corrosion cracks can form in the inner walls of those drille ...

Plasmonic metamaterials, composed of patterned metallic and dielectrics, can be engineered to have interesting optical properties that are attractive for a range of advanced obscurant applications. These particles are typically fabricated on planar surfaces, since patterning planar surfaces to achieve the desired effects is relatively straightforward.However, for planar geometries the particles op ...

In this proposal, AlphaSense, Inc. proposes to develop an innovative real time probe for online monitoring of plastic bonded explosive manufacturing process. Key innovations of the proposed sensor probe include: a) the use of a white light interferometer (WLI) to form real time images of the particles for accurate particle size measurements, and b) the use of quartz crystal microbalance (QCM) base ...

Mid-infrared (MWIR, wavelength ~10 micron) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in MWIR. The GaSb/InAs type-II Strained Layer Superlattice (SLS) MWIR detector has been under intensive investigation recently. While much progress has been made to enhance wavelength coverage, one of the few remaining issues has been its r ...
