The increasing penetration of MEMs devices into the commercial market has lead to an increasing demand for micro-sized electrical energy storage devices to interface with a support them. Electrochemical double layer capacitors hold significant promise as

Today the evaluation methods employed in the development and assessment of soldier borne Personal Protective Equipment (PPE) system designs are often extremely slow, expensive, and subjective, resulting in significant delays and expense in the fielding of improved designs. Recent rapid advancements in digital human modeling now allow the development of a multi-scale, comprehensive PPE evaluation t ...

A computational and experimental research program is proposed to develop and validate a high-fidelity 3D non-equilibrium magnetohydrodynamic (MHD) plasma compressible flow code for advanced aerospace applications. The code will incorporate a physics-based kinetic model of air plasma with non-equilibrium conductivity sustained by an externally applied electric field. The model will include electron ...

ABSTRACT: In this STTR phase II, HYPRES and University of California San Diego team will demonstrate a small size, weight and power Direction Finding (DF) system prototype based on SQUID array technology. High sensitivity, linearity, and wide bandwidth of SQUID arrays antenna sensors will be enable close spacing of smaller antennas even for high frequency (HF) range. Our SQUID array designs are ...

Intelligent tutoring systems (ITSs) hold the promise of dramatically decreasing the cost of training while also providing consistent, formalized instruction with automated trainee-assessment tools. However, the adoption of ITSs has been limited because: (1) most ITS systems are developed for specific, well defined, domains and cannot be easily adapted; and (2) they are time consuming and expensive ...

ABSTRACT: The ability to obtain time-resolved, direct wall shear stress measurement is an important asset to aerodynamic research, flow control and to enhance the fundamental understanding of the turbulent boundary layer. Due to a lack of reliable and affordable skin friction sensors, existing indirect methods are used to measure wall shear stress but their usefulness is limited since prior kno ...

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 ...

The technical objective of this proposal is to demonstrate a Quantum Cascade Laser (QCL) emitting in the 3.0-3.5 & #181;m wavelength region, which employs a metamorphic buffer layer (MBL). It is the goal of this program to develop a QCL single-stripe device which will operate in a single, diffraction-limited lobe under room temperature continuous-wave (CW) operation to moderately high (~ 0.5 W) ou ...

Waste heat from Naval diesel generators provides significant opportunity to introduce organic Rankine cycles (ORC) to increase their fuel efficiency. The objective of the proposed effort is to design and demonstrate a high-speed, spinning scroll expander (HiSSSE) ORC as a power dense waste heat recovery system for diesel generators on ships. The system will leverage Air Squared’s spinning scroll ...

Cemented cobalt-tungsten carbide is a material with attractive properties including high hardness and fracture toughness that has found success in a wide variety of applications ranging from drilling bits to armor piercing projectiles. However, with the classification of cobalt as a strategic and critical material that the US Department of Health and Human Services has classified as"reasonably ant ...
