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 ...

Additive manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complicated parts and greatly reduced cycle time. However, the AM process is complex and involves a large number of processing steps, each with its own set of uncertainties. These uncertainties compound through the AM build process, resulting in parts with widely varying properties across dif ...

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 ...

MicroLink Devices proposes to integrate its novel, high-efficiency, lightweight, and flexible solar sheet technology to a small unmanned aircraft system (UAS) that will provide a significant source of power, enabling long endurance flights spanning one full day to several days of continuous operation. This will be a breakthrough technology that will enhance the performance and utility of the Navys ...

Additive Manufacturing (AM) promises to be an innovative technology that can enable rapid manufacturing of complex parts at greatly reduced cycle time. With the maturation of selective laser melting (SLM) AM technologies there is increasing interest in applying this manufacturing method to the production of aircraft structural components, many of which are made of high-strength stainless steels. H ...

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 ...

In this Phase I STTR program, QuesTek Innovations, a leader in the field of integrated computational materials engineering (ICME) teaming with Prof. W.E. King from Lawrence Livermore National Laboratory (LLNL) as QuesTeks academic partner, proposes expand the computational Materials by Design technology by developing an Integrated Model Toolkit that enables the modeling of AM process by predicting ...
