Malicious modifications of hardware pose major concern in terms of reliable and trusted field operation of integrated circuits. To ensure security and trust of micro-chips, it is essential to develop efficient, low-cost techniques for detection of such tampering events. Conventional structural/functional testing, coverage metrics, and test generation approaches cannot be readily applied to identif ...

In prior research and development, the developers created Tyto Online, an online multiplayer sandbox game where middle school students engage in quests to apply life science learning. This project will extend the game by developing a prototype for the Earth and Space science domain, with a prototype including quests for the Climate and Weather topic aligned to Next Generation Science Standards (NG ...

Polyfluoroalkyl and perfluoroalkyl compounds (PFCs) have been used commercially since the 1940’s due to their high level of chemical stability, almost frictionless surface or waterproofing characteristics. Elevated levels of PFCs have been linked to cancer and other health problems including reproductive and developmental risks. PFOA and PFOS are amongst the most prevalent of the PFCs with low l ...

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 ...

DARPAs LUSTER program is currently advancing the state-of-the-art in Deep UV laser sources (220-240nm) developing the highest output power, smallest packaged laser system in the 220-240nm range. The goal of this LUSTER/PRIED-Portable Technology Demonstrator (LP-PTD) project is to develop the highest performing and smallest, Deep UV Raman standoff threat detection system. By highest performing we m ...

There is a need for non-invasive sensing of electrocardiograms and other vital signs to acquire information from high risk cardiac patients or other long term monitored subjects, continuously and without artifacts. The development of a new type ECG electrode sensor will assure patient compliance and allow this technology to be used long term while lowering medical costs. This proposal is to deve ...

Automobile three-way catalyst (TWC) are quite efficient at steady state operatingtemperature typically destroying 98% of incoming hydrocarbons (HCs) and carbonmonoxide (CO). However, up to 80% of emissions occur during the first fewminutes of Federal Test Procedure when the engine is running rich, the engine iscold and TWC has not reached light-off temperature. To significantly reduce HCsand CO ...

High loadings of particulate, inorganic fillers in organic binders are often desirable for some composite bulk property of interest. The loadings are limited by processing concerns, resultant composite mechanical properties, or both. When high loadings of a filler which bonds poorly (or not at all) to the binder are attemped, the composite strength falls below useful values. New techniques for ...
