Human interaction in cyberspace leaves indicators in the three layers that define cyberspace: persona, logical and physical. The proposed effort seeks to develop algorithms and software to integrate data and context across all three layers, “intertwining” data to create a more holistic and complete picture of cyber activity. Such an integrated perspective will allow cyber professionals to bett ...

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 ...

Cyber warfare is a rapidly expanding, critical battlefield for the US Navy. Attacks on infrastructure, ship systems, and sailors themselves can significantly reduce operational readiness and deployment time, and can be very costly. To prepare and successfully defend this rapidly evolving battlefield, defensive cyberspace operations (DCOs) must analyze and forensically investigate attacks, but few ...

Systems that operate in constrained environments depend on the acoustics in several ways. Harbor defense systems detect intruders (peopleand/or vessels) by either listening for their noises (passively) or by pinging on them and detecting their echoes (actively). Furthermore, suchsystems may also form the equivalent of an underwater cell phone network using sound to carry the information. The acous ...

Active imaging systems are used in degraded visual environments, like those found in marine fog and other areas with a high level of attenuation and scattering from obscurants like rain, smoke and dust. These systems are still limited in range and resolution. SA Photonics is taking advantage of new eyesafe, hybrid fiber-bulk laser technology capable of high pulse energy at high repetition rate to ...

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 ...

SSCI and MIT (Prof. Julie Shah) propose to develop and test a system that provides real-time assurance and trust in decisions made by autonomous collaborating vehicles. The proposed system is referred to as the RESTORE (Robust Execution System for Trusted Operation in Relevant Environments) and represents a decision support tool which facilitates decision making by the operator in cases when decis ...

Manufacturing of structural composites traditionally employs autoclaves to achieve high quality parts, including high fiber-volume-fractions and low porosity. A laminate comprised of stacked prepreg plies are cured under a vacuum in addition to ~7 bar of pressure to prevent formation of voids, particularly in interlaminar (inter-sheet/ply) regions. However, manufacturing composites within an autoc ...

This project focuses on the design, integration and optimization of a flexible natural gas combined cycle plant with carbon capture, capable of operating in a highly variable renewable energy environment. Renewable energy sources such as wind and solar power offer unique solutions in our quest to reduce global carbon dioxide (CO2) emissions. However, the increasing penetration of these high variab ...
