This STTR project will develop and validate a robust, scalable computational capability for the simulation of weapon-target interactions of interest to the Army. The proposed algorithm is based on the FLIP (Fluid Implicit Particle) - MPM (Material Point Method) - MFM (Multiphase Flow Method) approach and CartaBlanca nonlinear solver environment developed at Los Alamos National Laboratory. CartaB ...

DESCRIPTION (provided by applicant): Cepheid develops integrated sample preparation and detection systems for rapid molecular diagnostic applications at a point of use environment. Currently, Cepheid has the GeneXpert system, which is a cartridge and instrument platform for integrated sample preparation and real-time PCR detection of target nucleic acids in biological samples. The current config ...

In the phase I effort, IAI successfully demonstrated the feasibility of co-operative swarm based approach to boundary tracking. This approach is relevant to applications such as tracking oil spills using a swarm of robots, tracking enemy troop movement using a swarm of UAV's (Future Combat System (FCS) type scenario), and tracking of static and moving mine fields . In Phase II, we continue our ef ...

NextGen Aeronautics is proposing to refine the innovative actuator technology from PHAST Phase I and perform comprehensive bench tests under Phase II of this STTR. The proposed technology integrates piezoelectric, mechanical and hydraulic systems to create a system with the potential to provide damping, structural shape change, vibration suppression, flight control and precision pointing capabilit ...

Theoretical investigations and technology developments during last years have created new conceptual approach to design and build a new class of plasma wave electronics detectors of terahertz (THz) wave range. Terahertz radiation corresponds to the frequency bands of molecular and lattice vibrations in gases, fluids, and solids. THz detectors with higher sensitivity is urgently need for important ...

This proposal is concerned with the development of an advanced three-dimensional simulation facility for the analysis of environments such as produced by high-velocity impact of kinetic energy penetrators under the Army STTR Program. This facility will enable the Virtual Testing and Design of Military Systems with increased survivability as demanded by the Army's Future Combat System (FCS) and Obj ...

DESCRIPTION: Ultimately, the goal of this project is to produce a simple, non-invasive saliva test, which is able to assess caries risk. Within the Dental community, there is a trend to include prevention in the treatment plan. The test facilitates this move by offering the Dental professional, and ultimately the patient, the tool to determine the risk for caries development. Those patients who ar ...

We have developed a novel type of military obscurant that is based on the fabrication of composite particles with precisely defined geometries. These particles have very high infrared extinction efficiencies with peak extinction wavelengths that are directly correlated to the major and minor dimensions of the particles. By combining populations of particles, obscurants clouds can be produced that ...

We have developed a cost-effective process to improve the dissemination of particle-based obscurants. Surface coatings with defined chemical properties improve the obscurant dissemination characteristics by reducing inter-particle binding forces. This encapsulation method protects the particles from structural damage incurred during processing and dissemination, thereby improving their functional ...

Terahertz plasma wave detectors and emitters utilizing the high-density 2-D electrons in submicron AlGaInN/GaN-based Quantum Well Heterostructure Field Effect Transistors (QW-HFETs)with high-sensitivity levels for the sensing of terahertz (THz) frequency electromagnetic radiation are proposed and developed.
