ABSTRACT: Adversarial installations, such as those housing the means for nuclear weapons production, are increasingly being constructed in heavily fortified locations and often using ultra high performance concrete (UHPC) as the construction material. As such, the U.S. Air Force has considerable interest in further developments of ultra high performance concrete (UHPC) to maintain an advantage o ...

ABSTRACT: Feature extraction and target recognition suffer from a lack of a reliable model for both exploitable target features and the electromagnetic signature they possess. Signature data are often hard to interpret and invert to recover the target robustly. Bayesian learning approaches to statistical pattern recognition are based on the use of training sets of inputs and outputs, a data mode ...

ABSTRACT: Physical Sciences Inc. (PSI) and the University of Tennessee Space Institute (UTSI) propose to develop an innovative system to measure and control the cryodeposit layer thickness that develops on cold surfaces in cryogenic radiometric calibration chambers. The system includes: 1) an in-situ, interferometric-based instrument to monitor the cryodeposit layer thickness, 2) a mitigation sy ...

ABSTRACT: Optical Sciences Corporation (OSC) and the University of Alabama in Huntsville"s Center for Applied Optics (UAH/CAO) will demonstrate the feasibility and present a plan for developing optical instrumentation for the monitoring, mitigation, and removal of cryodeposits accumulated on optical and mechanical surfaces in cryogenic-vacuum radiometric calibration chambers. OSC will investigat ...

ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) ...

The Army desires carbon nanotube (CNT) based fibers with exceptional strength and stiffness to provide high performance composite materials. Physical Sciences Inc. (PSI) has demonstrated a method to fabricate continuous CNT from electrospun polymer nanofibers. Because these CNT are continuous, their mechanical strength is limited primarily to their defect population. During a Phase I program PSI w ...

The Mide/University of Colorado - Boulder team is proposing to use Boulder"s modeling capabilities to model the unsteadiness of the pulse generated pressures, temperatures and swirl to provide the flow information needed to optimize the turbine stages for

Current atmospheric diving suits and remotely operated vehicles (ROVs) have end effectors with simply 1 DOF. This rudimentary manipulation results in excessive time spent working a problem underwater, development of task specific tools that can be operated by the pliers or acceptance that a specific job simply can't be accomplished. Vishwa Robotics proposes a teleoperated, anthropomorphic end ...

Physical Sciences Inc. (PSI) and their academic partner, West Virginia University (WVU), are pleased to propose a uniquely innovative approach to measuring the three-dimensional air wake velocity field behind ship structures and towers. The velocity data is needed to support the validation of CFD models that will ultimately be used to provide sufficient safety margins for ship aircraft operations ...

Physical Sciences Inc. (PSI), in collaboration with Sandia National Laboratories, proposes to develop a high energy density (HED) power source based on the principles of thermophotovoltaics (TPV). The core technology of the HED power source is a novel high-temperature, spectrally-selective metamaterial emitter with a tailored emission spectrum matched to the external quantum efficiency spectrum of ...
