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 ...

Through a pilot study of in three high schools with a diverse mix of racially and socio-economically-diverse end users, the researchers will examine the feasibility and usability of the prototype when used by students. The team will also collect user-experience feedback on whether the prototype helped students consider different pathways, changed perceptions about the cost or benefit of higher edu ...

The team will develop a prototype of an augmented reality (AR) sandbox with foundational learning experiences in engineering and computer science for students in kindergarten to grade 2. The prototype will embed puzzle challenges within the AR interface to facilitate experiences that will mirror traditional real-world play-building activities. At the end of Phase I, in a pilot study in three class ...

methyst Research Inc. will design, fabricate and test a high uniformity, large area, low noise infrared trap-detector detector for the 1- 4.5 μm wavelength range. This state of the art detector will have a large area (e.g., 1-1.8 cm diameter active area) with a spatial variability of internal quantum efficiency of less than 0.1 % between 1 μm and 4.5 μm. In addition, the internal quantum effici ...

Galois will build a practical, efficient, modular, deductive code verifier and verification methodology for multithread C11 software. The verifier will take code written to the C11 standard, suitably annotated with function contracts, assertions, program/data invariants, ghost data/code, and any platform-specific assumptions beyond those guaranteed by the standard, and will prove that the code mee ...

This Phase II project will continue the prototype development of a pharmaceutical spray quality audit system. The spray quality audit system will estimate the planar mass distribution, mass flux, and drop size of pharmaceutical sprays that are used in functional coating applications and inhalers. A prototype tomography system will be designed and fabricated and evaluated using various fluorophore.

Video Demonstration of the Phase I Prototype: http://youtu.be/P716_x5KhPk Purpose: This project team will develop and test iASK, an app intended to assess and support increased word recognition among middle school students who struggle to read. The 2013 National Assessment of Education Progress reported that 66% of middle school students scored below proficient in reading, and 22% scored below ba ...

This project develops and evaluates the feasibility of a client-server application that integrates accessible life management tools for individuals with disabilities and those who support them in residential environments to improve the independent living capacity of persons with cognitive disabilities. A common database of information about an individual’s life and needs is developed providing r ...
