Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

Industrial facilities, manufacturing plants, and electric power plants that burn fossil fuels exhaust the combustion products to atmosphere through their smokestacks. Stack pollutant emissions are quantified using manual testing methods developed in the 1960s, which are prone to error if non-axial flow exists in a stack.Recently, NIST has been working on an improved technique of performing 3D flow ...

To evaluate the technical feasibility of prompt gamma neutron activation (PGAA) as an alternative to a set of standard destructive tests of concrete petrography including aggregate type, water/cement ratio, aggregate/binder ratio, density, chloride content and chloride bulk diffusion constant; and to determine the specifications for the design of a dedicated commercial laboratory-based PGAA facili ...

Unmanned systems and autonomous capabilities provide an avenue for improving enroute care in situations where medical evacuation assets are either not available or unable to reach the patient. A first step is to explore how intelligent algorithms can be u

The efficient design and evaluation of Army vehicles requires accurate simulation of the factors that affect the vehicle’s infrared signature and thermal conditions inside the vehicle. The model must account for all the transient heat transfer within and outside the vehicle, including heat from the engine, air flow within the engine compartment, exhaust system, ventilation inside the vehicle, th ...

Dignitas’ overall objective for Phase II is to enhance Cyber training capabilities by developing the Intelligent Cyber Adversaries Tool Suite (ICATS), a capable and flexible intelligent cyber adversary as a training tool for a target system such as OneSAF while looking forward to plans for next generation training system. ICATS provides automated cyber adversaries that conduct OPFOR defensive an ...

Mainstream Engineering has developed a 25 kW continuous, 35 kW peak-SiC based motor drive. The motor drive is cooled by the 105 °C engine coolant, includes an integrated EMI filter for compliance with Mil-Std-461, and includes reverse-polarity protection on both the 600 V power and 28 V control interfaces. The motor drive has a power density of 93 W/in3, weighs less than 12 lbs, and is 99% effici ...

PME proposes to extend the successes of the Phase I work with a Phase II prototyping effort which will demonstrate the feasibility of the approach on an actual vehicle with the controls running in real-time as well as corroborate the simulation results seen in Phase I. An existing vehicle will be up-fit with a preview sensing and active suspension system to characterize the combined system perform ...

Major benefits in performance, reliability, and sustainment cost have been demonstrated for a decade with a ‘new’ class of piston coatings that by their nature, improve the fit of mating piston to bore surfaces in the race and remanufacturing engine industries. Reliable high output engines are fundamentally limited by thermal and tribological performance of cylinder kit piston-ring-bore materi ...

Unmanned systems and autonomous capabilities provide an avenue for improving enroute care in situations where medical evacuation assets are unable to reach the patient. A first step is to explore how intelligent algorithms can be used to supplement the current capabilities by improving the diagnosis combat trauma to support prolonged field care. Variability in the sensing technology available, and ...
