Human social interaction is complicated by ambiguous identities, misinformation, misdirection, and flexible alliances. Additionally, thanks to the internet, authors can post messages from anywhere in the world, in diverse forms, and with different personas. Current solutions are challenged to accurately identify and characterize authors across platforms and data types, let alone infer authorial in ...

Rugged, comfortable and reliable physiological monitoring systems are required to allow military commanders and medical personnel to assess the basic health and readiness of the warfighter. Direct monitoring of the health and status of individual warfight

TIAX will build, characterize and abuse test lithium-ion cells employing LiCoPO4 cathodes and control metal-oxide based cathodes (such as LiCoO2 ) opposite graphite anodes. In Phase I, TIAX will perform overcharge and external short circuit tests to the specification of the UL1642 standard and will also perform nail penetration tests on both types of cells. In the option program TIAX will perfor ...

The inability to plan in real-time is a major reason why robot manufacturing is restricted to high-value, high-volume products, in carefully engineered factories where robots blindly repeat pre-programmed trajectories. Today, robots simply cannot generate collision-free motion on the fly. We are solving this core problem—real-time motion planning in unstructured, fluid environments and on divers ...

A new approach is proposed for Accelerated Modifications using Physics-substantiated Safety Arguments (AMPS). We leverage evidence-based certification methodology and Safety Arguments (SAs) to map modifications to system architecture and behaviors. We integrate formal methods to build SAs that trace the impact of modifications through complex system interactions. AMPS connects SAs to critical desi ...

ABSTRACT: For certain weapons systems, lethality is directly correlated to the orientation of the weapon with respect to the target at impact, also known as the angle of incidence (AOI). Accurately measuring AOI is of the utmost importance in developing and advancing state-of-the-art precision weapon systems. Currently, there is no commercially available sensor system for measuring AOI to the pre ...

UUVs have become increasingly important tools in the collection of environmental data. Their unique ability to operate independent of surface vessel conditions allows oceanographic seawater measurements when traditional means is not possible. Historically sensor packages for UUVs have been based on adaptions of ship deployed equipment. Recent development in sensors, such as the Hybrid Flow Through ...

Although great strides have been made in the development of simulators for training technical and teamwork skills, much less progress has been made with regard to skill assessment. Typically, performance is measured using a rating scale with anchors ranging from"low"to"high."Such methods are too coarse to provide an accurate assessment of individual or team performance. What is needed are unobtrus ...

A reliable 20-year shelf life power source is needed to activate advanced smaller munitions. Most of the current batteries and other power sources do not have such a long shelf life and reliability. The only battery chemistry proven for such a long life and reliability has been used only for very low power applications due to limited ionic conductivity of the electrolyte. Materials & Systems Re ...

Theater missile threats often fly through and maneuver at high altitudes, where their signature can substantially change. New chemical signature mechanisms and non-equilibrium conditions will become important. The new mechanisms change the appearance of threat signatures and must be taken into account when developing detection, track, and guidance sensors and algorithms. Spectral Sciences Inc. (SS ...
