Additive manufacturing is steadily advancing towards fulfilling its promise of customized and on-demand production of functional parts. However, performance of as-manufactured parts can differ significantly from the as-designed parts because the as-manufactured geometry differs from the as-designed geometry and the asmanufactured material properties are not known. Attempts to predict performance o ...

During the Phase I effort, Semandex Networks and its team developed a prototype capability to detect trends in research publications by automatically identifying emerging concepts within the data. The implemented capability provides insights into past and

The Radionuclide Aerosol Sampler and Analyzer (RASA) is a completely automated monitoring system that detects airborne radioactive particles and is one of the detection systems used in the U.S. and global International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) to detect nuclear detonations. Mainstream proposes develop a high-efficiency cyclone separa ...

The detection of radionuclide aerosols is a critical indicator of a nuclear detonation. Existing sensors as part of the International Monitoring System operate in a batch process and typically have a 48 to 72 hour delay between aerosol sample collection and measurement activities due to limits of instrument sensitivity. The continuous, instantaneous measurements of atmospheric aerosol radiation le ...

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 ...

Although protocols for securing email have been available for over twenty years, these protocols, by nature of their use of asymmetric cryptography, require users to have the public key or certificate of the correspondents. Grier Forensics will develop technology to use the Domain Name System (DNS) to distribute certificates and keys, making email secure, authenticated, and confidential, curbing t ...

A CONCEPT FEASIBILITY STUDY FOR A SATELLITE-BASED OPTICAL-INFRARED DISTURBED ATMOSPHERE SIGNATURE PROGRAM IS PROPOSED. THE INITIAL CONCEPT IS FOR A POLAR-ORBITING OPTICAL-INFRARED ANALOG TO THE HILAT SATELLITE WHERE-IN A HIGH PROBABILITY OF AURORAL ACQUISITION IS ANTICIPATED. INITIAL TECHNICAL DIFFICULTIES OF CRYOGENIC OPERATION AND EXPECTED LIFETIME ARE DISCUSSED IN TERMS OF THE IRAS SUCCESS. THE ...
