The US Navy is moving towards a Single Sortie Detect to Engage (SSDTE) paradigm to implement in-stride minehunting and mine prosecution. Integrating in-stride Mine Search and Mine Prosecution functions is a key requirement to achieve the SSDTE paradigm. Mine Target Reacquisition between the mine search operations and mine prosecution phases poses a particular challenge, as planned mine prosecution ...

Current prosthetic feet produce much less peak mechanical power than the able-bodied foot/ankle and release only about half of the mechanical energy generated during gait. This leads to higher energy expenditure among amputees as compared to able-bodied i

Orbit Logic,the University of Colorado, and the University of California are developing a hierarchical autonomous mission planning and response capability for Autonomous Underwater Vehicles (AUVs) to address the challenges associated with long duration operations. The research is innovating approaches to the exchange of information between collaborating vehicles enabling onboard decision-making to ...

The U.S. Navy has initiated a program to develop the next-generation Joint Counter Radio Controlled Improvised Explosive Device Electronic Warfare (JCREW) 3.3 system to detect and jam enemy improvised explosive devices (IEDs). The objective of this propos

Functional encryption (FE) is a new vision of public key encryption that allows access controls to be embedded within a ciphertext. This project has three main components: (1) develop an FE toolkit and FE-based key management service, (2) conduct essential cryptographic research to support deployment, and (3) explore opportunities for interoperability and integration for FE with existing and futur ...

The OASIS/WHOI team will design and develop a long-range under-ice acoustic navigation and telemetry system. The Phase I work has resulted in a much-improved model for under-ice acoustic propagation and an in-depth exploration of the potential for regional scale (200-500 km) acoustic navigation and communication. Phase II work will focus on bounding the design problem and selecting a suitable freq ...

This STTR aims to develop a novel method for detecting and tracking growth of cracks in rotorcraft gearbox. Aerospace structures are subject to dynamic loading. In particular, gearbox components experience continuous cyclic loading, wear and eventually develop fatigue cracks. As opposed to most other aircraft components, gearbox components are non-redundant, so a failure can have catastrophic cons ...

Submarine commanders must make complex decisions to accomplish increasingly diverse missions. Moreover, concurrent missions may involve contradictory requirements. Planning must also account for the unexpected, including equipment failures, environmental factors, or external events that impact the ship's mission(s). Since all submarine operations involve a degree of risk, the commander must b ...

We envision a coherently coupled QCL array architecture featuring 2nd order DFB gratings to vertically couple out light with excellent beam quality and high output power. This approach does not require cleaving of the devices or facet coatings and is therefore inherently more robust and manufacturable than facet emitters.

The low weight, excellent durability and heat resistance of ceramic matrix composites (CMCs) make them attractive materials for use in aircraft engine hot sections, where improved overall engine efficiency can be realized. Nevertheless, the interlaminar properties of CMCs must be well understood before CMCs can realistically replace metallic superalloys in engine hot sections, and no standardized ...
