Our objective is to provide a semi-automated system to generate and verify scalable, high fidelity, multi-dimensional, social networks with realistic distributional, temporal and spatial characteristics as networks and as event sequences. This enables the user to generate networks varying in size, node attributes, geo-temporal characteristics, consistency with other networks, and reflection of kno ...

Before beyond line-of-sight UAV operations can be permitted, three key requirements must be met.UAVs must be capable of safe flight without relying on a remote operator; they must be able to avoid static and moving obstacles; and must be able to guarantee accurate navigation in the absence of GPS.We propose a 24-month program to develop a family of miniature navigation and guidance solutions that ...

The objective of this proposal is to investigate a set of software tools that aid researchers (i.e. scientists, inventors, designers, planners, or investors) in solving complex problems over large sets of data. The DiscoveryToolsTM system will provide acustomer-centered approach to computer automation. The customer (i.e. researcher) encodes problem-solving strategies through an easy-to-use graph ...

While unmanned air vehicles are starting to operate in complex urban and indoor environments, many challenges still remain. In the proposed project we will develop a team of flying robots that can explore and map environments such as networks of underground tunnels. We will address three key challenges: First, the tunnel network topology is unknown and will have to be discovered incrementally by t ...

Video Demonstration of the Phase I Prototype: http://youtu.be/vS0XzzPl3iU Purpose: This project will develop and test Happy Atoms, a physical modeling set and an interactive iPad app for use in high school chemistry classrooms. Happy Atoms is designed to facilitate student learning of atomic modeling, a difficult topic for chemistry high school students to master. Standard instructional practice ...

A thick SiC epitaxy process was demonstrated by SemiSouth in Phase I, as the growth (or deposition) rate was boosted from 5 um/h to 20 um/h, and thickness uniformity was kept to 5% or below. In the Phase 2 effort, it is proposed that the processes be developed for production by re-designing and optimizing the reactor susceptor in a research reactor to minimize cost and risk. Specifically, the su ...

The overall objective of this Phase II project is to optimize the fabrication procedure associated with the chemical lithography proposed in Phase I to fabricate nanophotonic structures and devices at a fraction of the cost of existing technologies. We plan to use our optimized chemical lithography procedure to fabricate an ultra-high resolution patterns and devices including nano-probe for near f ...

In Phase I, EM Photonics demonstrated the viability of using a reconfigurable hardware approach to accelerating the simulation of electronic circuits based on their electromagnetic properties. In Phase II, this technology will be used to create a solver capable of analyzing mixed signal circuits 64 times faster than is currently available from equivalent software. The resulting device will shrin ...

The goal of this project is to produce prototypes of a modular solid state heat pump based on a novel thermoelastic effect. The heat pumps will be tested in a portable, battery powered cooler for a chemical suit, such as those used in environments subjected to bio-chemical attacks. The new thermoelastic heat pump is particularly suited for such an application because it has high power density (s ...
