ABSTRACT: The physical scalability of Si based nonvolatile memory is problematic for the terascale integration of space memory. In particular and with regards to Flash, this problem is two-fold as device designs breakdown and photolithographic patterning approaches its limits to minimum feature size. Whereas phase-change and ferroelectric polymer devices have shown promise to scale beyond Flash ...

ABSTRACT: The K-128 co-processor leverages insights from neuroscience to achieve superior performance. Unlike previous efforts along those lines, our approach is to create a software programmable co-processor that runs existing applications. One of the most salient characteristics of such a co-processor is its power efficiency: not just a few percent more efficient than a traditional processor, b ...

ABSTRACT:For GPS denied navigation, there is a need for developing inertial measurement units (IMU), employing gyroscopes and accelerometers, with better accuracy and/or smaller volume and weight than the state of the art.Under Phase I, we have established the feasibility of realizing a superluminal ring laser gyroscope (SRLG) and a superluminal ring laser accelerometer (SRLA), based on diode-pump ...

In this proposal, AlphaSense, Inc. details the development of a fully integrated laser ultrasound visualization and laser ablation tool for corrosion identification, removal and cleaning. The key innovations of this proposal include the following: a) Hidden corrosion detections based on direct visualizations of the ultrasound propagation characteristics, b) Corrosion product removal using laser ab ...

CRAFT Tech proposes the development of an innovative design optimization tool called"AeroRCS"which will simultaneously solve for both aerodynamic performance as well as electromagnetic reflectivity (Radar Cross Section). When operated in an automated environment, AeroRCS will intelligently"morph"and steer the shape to converge on an optimal solutions. AeroRCS will be demonstrated by developing ...

Modern combustion systems such as liquid rocket engines and gas turbines are characterized by high operating pressures and temperatures due to increased power-density. Thermal radiation has significant impact on both heat fluxes at the wall and on physical phenomena controlling the combustion process at these conditions. Coupling between radiation, turbulence and chemistry can have a large effect ...

Evolving demand for robust and accurate multi-physics modeling tools for high performance combustion devices is being driven by increasingly complex design, analysis, and simulation requirements, but existing models and their underlying assumptions need to be rigorously examined in light of their intended Air Force propulsion system applications. The production use of coupled multi-physics module ...

Archangel Systems, Inc. proposes a feasibility study coined Triaxial Accelerometer with Low Offset and Noise (TALON) to meet the accelerometer needs for DoD"s next-generation IMUs in agile missile programs. DoD targets for IMU size, weight and power (SWAP) budgets are aggressive. To meet these requirements, TALON leverages prior Archangel work for DARPA"s NGIMG project. Specifically, the MEMS a ...

We propose to develop a space based radiation hardened GPS transmit antenna capable of forming spot beams to enhance the GPS signal on the ground by greater than 5 dB. It is expected that our transverse compound hybrid antenna will provide as much as 30 dB gain over a hemispherical antenna allowing enhanced signals over specific areas as large as 500 km. A tradeoff between spot size and signal g ...

ABSTRACT: Military and industrial personnel are often exposed to RF electromagnetic energy which can cause thermal and electrokinetic biological effects. To understand these effects, AFRL is using computational electromagnetic tools to predict RF energy deposition and thermal effects in humans. Unfortunately, high resolution thermal simulations are computationally very expensive. The goal of this ...
