Grammars for Graph-based Assessment of Mission Readiness (GGRAMR) provides a framework for estimating measures of performance (MOPs) based on diverse data stored in large graph databases. GGRAMR starts with information stored in a service-wide Rya graph database (Punnoose, Crainiceanu, and Rapp, 2012), transforms the big graph into a new graph that directly calculates readiness assessments, and th ...

Cyber physical systems are employed widely in Navy operations. As these systems become more interconnected, they become more exposed to cyber-attacks. Traditional fault tolerance techniques that use redundant hardware and software are designed for physical and random failures that are unintentional; they are far less effective against intentional attacks that target all redundant components. There ...

The littoral environment is especially demanding on tactical sonar systems, in large part because the spatial and temporal variability imposes sonar system operating conditions of a nature and with a scale heretofore not encountered in the open oceans. Recent Office of Naval Research (ONR) sponsored basic research as well as fleet exercises have shown that littoral environments tactically importan ...

Social media is transforming the way people around the world share messages, receive information, and come together to act. Unlike most traditional media, social media’s technical foundation enables messages to spread quickly and widely. This technology can also be used to disguise the true source of messages and produce automated messages that may have influential and manipulative effects on po ...

We propose development of a software capability which, based on use of accurate and efficient exact-physics computational electromagnetics (CEM) solvers together with CAD-import (Computer Aided Design) and direct CAD-to-EM capabilities, will enable optimization of the properties of on-platform pRFID tag/reader antenna systems. For accuracy and modeling flexibility the proposed codes are based on M ...

An advanced Li-Ion Battery Management System for DOD mission and safety critical platforms. The majority of Li-Ion Battery Management Systems (BMS) for DoD aircraft, helicopter, and directed energy weapons are custom designs for the individual Aerospace platform. This leads to increased cost over the battery life cycle due to the requirement to maintain the production facilities which produce repl ...

This Phase II effort aims to deliver robust, reliable software that instantiates state-of-the-art feedback pseudospectral optimal control algorithms for flight trajectory optimization. The computation and real-time implementation of controls in nonlinear systems remains one of the great challenges for applying optimal control theory in demanding aerospace and industrial systems. From proportional ...

Magnetic materials with high hesitivity values are needed to achieve low-profile conformal broadband magnetodielectric antennas with significantly enhanced efficiency in HF-UHF. The higher the hesitivity, the higher the attainable efficiency in these magnetodielectric antennas. State of the art hesitivity as high as 6×10^6 O/m has been reported in CoZrNb alloy films. Further hesitivity improvemen ...

Reducing the violence of Slow Cook-Off (SCO) and Fast Cook-Off (FCO) to acceptable levels is of great interest to the Insensitive Munitions development. For example, the MIL-STD-2105C SCO test for Insensitive Munitions (IM) compliance requires a slow heating rate (3.3°C/hr) until reaction occurs whereby the ensuing reaction is characterized by degree of violence. A Type V (burn) reaction or bette ...

Recent reports indicate the activity of more than 6,000 botnet C and C servers. 70 million zombies are responsible for 80 percent of SPAM. Given the exponential growth of the botnet threat, the security of our nation s cyber infrastructure demand automated botnet activity monitoring solutions. In Phase I, Milcord developed a feasibility prototype of a Bayesian Activity Monitor for Botnet Defense. ...
