Social network analysis has become one of the most powerful analytic tools in both private and government sectors and a key source of information on individuals and groups. Recently, social media arose as an important source for social network data in both sectors. Unfortunately, theoretically motivated approaches to social network analysis have not been able to keep pace with the new informationa ...

Sensor development researchers and engineers have perpetually sought novel methods to reduce sensor size and improve performance. Continued miniaturization of sensors through micromachining has enabled novel applications and introduced new paradigms for engineered systems to interact with the world. The challenge has always been to improve performance while continually reducing size. In the curren ...

To address the Army"s Phase-II requirements for a low-cost chaos-based radar demonstrator, TechFlow and its research partners- the University of New Mexico and Forza Silicon Corp., will implement and test a prototype E-band chaos radar system incorporating a coherent receiver. In Phase I, the TechFlow team performed a comprehensive study of the coherent chaos-based modulation scheme described by C ...

The goal of this project is to design and build a THz-frequency spectrometer prototype with sub-wavelength spatial resolution for use in the spectroscopic and temporal analysis of trace material samples in advanced sensing and monitoring applications. The instrument operating at room temperature will include a periodic-grating microfluidic sampling system with controlled precise sample placement a ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

The overall objective of this proposal is to evaluate the new in-situ growth monitoring system, Auger Probe, in an MBE environment for reliable and reproducible, highly precise results. State-of-the art data manipulation techniques will be used without impacting the growth process (MBE in this case). Using Auger Electron Spectrometry (AES), the Probe system will be used for in situ, real time an ...

The proposed work will result in a method for production of dense, hard, tough, strong tungten carbide (WC) ceramic material for ultimate use as the penetrating core in armor piercing projectiles. Focus is on the development and feasibility of a titanium silicon carbide (Ti3SiC2) based matrix as a replacement for cobalt based materials currently used. Ti3SiC2 is a so called ductile ceramic which ...

Ultrafast true random number generators are ideal for data encryption, Monte Carlo testing, and other data transport applications. Torch"s team has extensive experience designing, building, and testing oscillators based on the innovative, hybrid, exactly-solvable, chaotic oscillator theory as developed by Corron, Blakely and Pethel. These oscillators are capable of generating provably-chaotic wa ...

The low density of magnesium makes it of interest for the development of advanced materials having high specific strength and stiffness. Current Mg applications, however, are limited by the performance and cost/quality relationships of existing Mg-alloy systems. One approach to obtain improved Mg alloys is through the development of new alloys and/or Mg-based composite materials that are enabled t ...

Antimicrobial treatments have been incorporated in a number of textile products used by the U.S. Army to control odor and reduce skin irritation, thus improving the quality of life for the warfighters. Current textile treatment using chemically-derived antimicrobials such as metals (silver- and copper-based compounds), polyphenols, halamines and quaternary ammonium compounds can effectively kill o ...
