Filamentation of ultra-short laser pulse propagation in non-linear media offers significant potentials allowing to address numerous problems in military and commercial sectors. However, practical implementation of this requires an ability to control the USLP at its propagation through inhomogeneous media, like turbulent atmosphere. On the basis of our approach for combating turbulence effects on p ...

We propose development of an improved bottom database suitable for use in the frequency range of 1-10 kHz. Measured transmission loss (TL) and reverberation level (RL) will be jointly processed in building the database. The influence of the rough sea surface, rough seafloor, as well as subbottom heterogeneity will be accounted for during database generation. The rough sea surface will be character ...

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 ...

ATA Engineering, Inc. (ATA), partnered with a nonprofit research institution, CUBRC, Inc., (CUBRC), proposes a Phase II STTR project to further develop and continue validating a novel multiphysics simulation technology. The project team will implement the technology in a fluid-structure-material interaction (FSMI) software toolset that incorporates mutual interactions between aerodynamics and stru ...

As the orbital space around the earth gets more and more crowded with civilian and military reconnaissance, weather, tracking, communication, and navigation satellites - civilian and military users become increasingly dependent on the services provided by these spacecraft. This situation increases the possibility of offense actions against some or all of these spacecraft. The possibility calls for ...

This effort will analyze publicly available online communication data, uniquely applying empirical results from the cognitive bias literature, to quantify the impact of cognitive biases on exposure to, use of, and propagation of online information. SoarTech, with its partners, will develop and evaluate methods to identify and measure cognitive biases in online information environments. The team wi ...

We propose to investigate, in collaboration with MGH Voice Center and Altec, Inc., application of surface electromyography (sEMG) to assessing cognitive workload, strain, and overload. Specifically, sEMG sensors placed on the face and neck will detect emotional/motor responses to workload strain. The proposed effort will build on the substantial sEMG experience of our partner, MGH (including resea ...

The U.S. Air Force is interested in developing hypersonic vehicles including reusable transport aircraft, cruise missiles, and unmanned systems. Hypersonic flight regimes result in multifaceted and very difficult design challenges that can be encapsulated into an aerothermoelastic problem, which is a complex interaction of structural, thermal, and aerodynamic mechanisms. When a flexible structural ...

A nondestructive test system is under development for thorough, rapid and economical evaluation of the structure and properties of polymer-inorganic interfaces during curing and in service. The system is capable of in-situ, real-time and spatially resolved monitoring of the molecular structure and properties. It employs (single-sided) NMR relaxometry principles to detect and quantify defects and d ...

Vadum proposes to mature its Vibration-Enhanced Underground Sensing (VENUS) technology into a reliable, shallow-buried low-metal-content landmine discrimination and classification solution with minimal False Alarm Rate (FAR).  VENUS exploits a novel vibration phenomenology to provide unique discriminatory information and estimated classification of the buried target that enhances and complements ...
