Qualtech Systems, Inc. (QSI), in collaboration with Vanderbilt University (VU) proposes to develop a state-of-the art Health Management System (HMS) system consisting of a small form factor GPS-enabled onboard computer, a small display for crew, and sensors for boat and engine vibration, OBD data, engine oil quality monitoring, and battery health monitoring. The HMS system will provide Wi-Fi and w ...

CL-20 is the most powerful conventional explosive known, but its high cost has limited its adoption in a range of potential applications. Par of the challenge in making these materials is the complexity of the reaction used to prepare the polycyclic cage. The complexity of this reaction makes it difficult to have insight into the reaction and to improve it. Additionally, several of the intermediat ...

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 ...

We are developing a platform for pharmacometric data analysis workflow that is much more flexible and efficient than anything else on the market. This will be accomplished by (1) developing new functions within Stan, a widely used, open-source, probabilistic programming language and Bayesian inference engine, for computationally efficient data analysis using complex differential equation models, ( ...

PEI will development and design a light weight, resistant to corrosion and ice adhesion, water tight and low maintenance VLS Composite Missile Hatch. PEI design will include polymers and nanofibers and materials, will utilize low costs composite manufacturing, design, performance evaluation, and analysis techniques will enable us to develop a cell hatch that will meet all performance requirements. ...

This STTR is aimed at developing methods and tools to characterize the impact of free-play on control surface flutter and overall stability and performance of the system. A successful completion of this two-phased STTR effort will lead to a modeling, analysis, design, and simulation tool that will provide a state-of-the-art capability for stability and performance analysis for any generic control ...

Development of an energy harvesting system utilizing the magnetostrictive material, Galfenol, will be completed in this effort. The energy harvesting system will consist of Galfenol plates or sheets, magnetic circuit components, coupling structure, power conditioning electronics, sensor, and wireless transmitter. Lab testing and relevant environment testing through sea-trials will be completed on ...

A software toolkit for Abaqus (XSHELL) will be developed for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading. The mesh independent crack description and fracture energy dissipation will be achieved in XSHELL through the implementation of two overlay elements with an embedded cohesive interaction along an arbitrary crack segment w ...

The SKATE concept was designed to quantify skill levels of trainees, teams, or units, generate skill-appropriate training scenarios, and provide a continuous skill-level assessment of disparately skilled trainees, teams, and units in a joint training exercise while maintaining the overall integrity and realism of the mission itself. SKATE evaluates the skill level of an individual, teams, or unit ...

This proposal describes the proposed implementation of the concept of the Quality of Training Effectiveness Assessment (QTEA) system. This concept was developed in Phase I (N074-028-0065). Currently, VE design is guided by subjective design models that involve multiple design iterations and focus on trial and error. Our approach is innovative and new because it quantifies VE fidelity requirements ...
