Novel approaches are needed to improve the performance and reduce the size, number and signature of antennas with significantly enhanced efficiency in HF-UHF. It has been shown recently hesitivity, which is able to characterize the performance of the material and categorize the radiation efficiency of magnetodielectric wire antennas; the higher the hesitivity, the higher the attainable antenna eff ...

The Navy is continually developing new technologies to improve warfighting effectiveness. These technologies risk overloading Aircrews physical and cognitive capacities, thereby degrading performance. To mitigate that risk, the Navy needs a system to assess Aircrews physical and cognitive workloads unobtrusively and objectively. Such a system must (1) perform real-time data collection in a robust ...

The introduction of new systems and technologies is critical for maintaining superiority, yet this brings with it uncertainty regarding the impact on users, teams, and organizations. Rigorous test and evaluation (T&E) practices are therefore essential prior to acquiring and instituting new technologies, particularly to assess the workload imposed on end users. Traditionally, workload assessment ha ...

TDA has teamed up with Lawrence Livermore National Laboratory as its research institution collaborator to address the target STTR topic objective of quantifying the uncertainties in the mechanical behavior of the AM parts. To quantify uncertainties by minimizing both the computational burden and expensive testing and also overcoming the IP concerns, we propose a novel approach with three layered i ...

The goal of the proposed research is to develop light-weight, flexible, high efficiency solar cells made from perovskite halide light-harvesting materials for use on unmanned aircraft systems (UAS), for use in conjunction with an energy storage system. Solar cells have historically been heavy, costly, and inflexible. In this research, low-cost manufacturing methods will be used to make high effici ...

Hepburn and Sons LLC teamed with Florida State University (FSU) Center for Advanced Power Systems (CAPS) propose to develop an affordable, general method for grounding Medium Voltage Direct Current (MVDC) zonal electrical power systems for naval warships. The grounding system concept developed in Phase I will evaluate the incorporation of electric weapons and high power sensors while accounting fo ...

Cyber security forensic functions depend on highly structured conformance to log formats for generation and transmission capabilities including identity, network time stamps and event message formats. Without this structure there is no effective way to reconstruct the time sequencing patterns that reveal the presence of unauthorized actions and actors inside of a network. Limitations in the capaci ...

The ubiquity of high-resolution imagery and video taken by surveillance cameras, handheld cameras, vehicle-mounted cameras, and airborne cameras is creating a rich source of dynamic data that offers opportunities for effectively solving defense, security and law enforcement problems. But in order to develop effective scene and activity understanding applications we must develop robust, accurate an ...

This effort is focused on establishing an important capability of providing a comprehensive, advanced model of the three-dimensional acoustic field, including propagation, scattering, and reverberation in complex and dynamic environments. This new 3D acoustic model would feed the Navys sonar performance estimation tool with a purpose of addressing the optimal placement of sensors in complicated en ...

The marine environment is extremely corrosive to turbine engine components due to the large amount of salts from the sea coupled with the fuel impurities and the high temperatures experienced. To cope with future operational requirements, a strong need exists to develop novel, protective coatings to provide environmental protection from hot corrosion and oxidation conditions across a wide range of ...
