This Phase II STTR proposal will develop a computational tool for state-of-the-art computational modeling of multi-scale thermo-mechanics of heterogeneous energetic materials. The proposal will bring together researchers with long-standing expertise in flow software and physical modeling of high-speed reactive multi-material flows to work on further developing a cutting-edge computing tool called ...

Realistic surgical simulation requires a combination of representative tissue geometry, accurate tissue material properties and lifelike tool-tissue interaction forces. Recent advances in computational power and imaging modalities have provided the capability to represent the anatomical details required for surgical training; however, the mathematical models which govern the underlying tissue pro ...

Ultrasound is a therapeutic modality which has been used clinically for 60 years, but has been limited in practice by the complexity of the technology. Recent research has allowed for the development of a portable, wearable, long duration, low intensity therapeutic ultrasound system. The system is powered by battery, and can be applied by a user to deliver up

Nalas Engineering and Johns Hopkins University collaborated in a Phase I STTR program to study reactive mixtures of HI3O8 and nanocomposite fuels previously developed by the Weihs Group. These fuel/oxidizer mixtures are uniquely able to simultaneously produce heat and biocidal iodine gas, a combination designed to destroy biological weapons. The team at Nalas focused on evaluating conditions for p ...

This Small Business Technology Transfer program will develop a spectroscopic polarimeter-on-a-chip using novel plasmonic resonant cavities sensitive to linear polarization over a narrow wavelength range. Spectral selection will be possible through geometric scaling, with this work concentrating on the visible to near infrared wavelength band. Dielectric gratings with subwavelength period will act ...

In this Phase II program, Voxtel will design, manufacture, and benchmark-test additive-manufactured (AM) insulators capable of electrical stress greater than 25 kV/mm, for use in high-electric-field applications, such as high-power microwave (HPM) devices. These insulators will sustain vacuum of 10-7 Torr and withstand 20 psi of pressure. To achieve this goal, Voxtel will synthesize readily additi ...

ABSTRACT: We propose to develop an assured information sharing framework for cloud-based systems that leverages our ongoing work in the areas of policy-based usage management and semantic interoperability. The development of this framework will involve the creation of a novel approach to information sharing that treats security as a commodity that can be dynamically provisioned within the cloud, ...

ABSTRACT: RNET and The Ohio State University propose to use algorithmic modifications and multi-level parallelization techniques and tools to improve the scalability of the aero-line/aero-elastic coupled CFD/CSD codes relevant to the DoD/AF (e.g., CREATE/Kestrel). The optimizations will address inter-node and intra-node parallelization to better target emerging compute architectures (e.g., multi ...

This proposal addresses the need for development of room-temperature ionic liquids (RTILs) for use in electrolytes for reversibly electroplating films with specific optical, emissive and electrical properties on demand. Target applications for these electrolytes are devices using reversible electroplating for tuning/regenerating functional surfaces, such as mirrors or thermal emitters, deployed on ...

Designing an efficient and effective film cooling system to protect critical components of modern rocket engines requires a significant number of problems and challenges to be addressed. Complicating the already difficult hydrodynamic challenges, thermal and/or catalytic cracking of hydrocarbon fuels is always accompanied with coke formation. Coke deposits on combustor and nozzle walls reduce heat ...
