Award Data

High fidelity, large scale simulations of complex systems pose a very difficult situation to the scientist trying to understand the physical domain and characteristics of their system. Often, it is impossible to manually search through the data that can come out of these simulations, which may range from Gigabytes to Terabytes. Furthermore, it may be impossible to visualize the multi-dimensional i ...

Providing commanders with accurate, on-the-spot, clear, concise, usable information wins battles and saves lives. With incoming information from many heterogeneous sources, the focus has been primarily on determining what information to present, and visual ways of communicating the information. There has been less research on what makes information actionable, or on what additional communication c ...

A low-cost fiber-based octave-spanning frequency comb system operating in the mid-IR region is proposed, which is based on femtosecond-Tm-fiber-laser-pumped supercontinuum generation in a mid-IR-transmitting dispersion-engineered fiber. An all-fiber femtosecond mode-locked Tm-doped fiber laser at 2 micron will be used as a seed source for mid-IR supercontinuum generation. A femtosecond soliton fib ...

Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution met ...

The proposed barium strontium titanate (BST) nanodielectric devices will combine some of the best features of bulk and thin-film based tunable dielectrics: low microwave losses, high tunability at high fields, the potential for low operating voltages, and less temperature dependent dielectric response. The miniaturization of devices and reduction of insertion losses requires developments of mater ...

CMU and Magnetics, A Division of Spang and Co. have developed a new high-saturation induction, high-temperature nanocomposite alloy for high-power inductors. This material has FeCo nanocrystals with an A2 or B2 structure embedded in an amorphous matrix. Field annealing resulted in a linear B-H response with a relative permeability of 1400, constant up to fields of 1.2 T. The material was used in ...

Our Phase I program will extend and validate a high-speed engineering transitional model (ETM) using new CUBRC data sets (such as HIFIRE-1) of interest to the Air Force. The ETM is responsive to tunnel noise and wall heating, and predicts the overshoot in heat transfer observed in transitional data. The model solves PDEs for transition onset as well as for an intermittency parameter that blends th ...

FBS, Inc. and The Pennsylvania State University propose the development of a novel ultrasonic structural health monitoring (SHM)/nondestructive testing (NDT) technology. The goal of our work is to bridge the gap from the short time transient ultrasonic guided wave analysis to the long time modal vibration analysis. This new technique will be sensitive to material properties, defect presence, and ...

The opportunity identified here is to expand the capabilities of Multicontinuum Technology (MCT) for prediction of failure initiation in complex (hybrid) composites. A successful Phase 1 project will demonstrate good correlation of MCT variables with initial failure in composites with complex multiscale reinforcement architectures. A Phase 2 project would refine the predictive capabilities, embo ...

Cyber-attacks targeting our info-structure are being launched continuously from hostile locations. It is becoming apparent that securing US info-structure and preventing cyber-attacks cannot be met with existing techniques. By continuously monitoring and analyzing cyber-space applications, services, and resources and through the use of autonomic agents, AppFlows, data mining, and multi-level cyber ...
