ABSTRACT: In order to effectively utilize multiple Unmanned Aerial Vehicles (UAVs) for missions such as Intelligence, Surveillance, and Reconnaissance (ISR), Strike, etc., it is vital to have Open Architecture (OA) tools that accurately model and simulate the interaction of autonomous, unmanned, and manned air vehicles. Daniel H. Wagner Associates (DHWA) proposes to develop automated, efficient, O ...

The development of a high fidelity, generalized computational framework with the necessary physical submodels incorporated for the analysis of multiphase, combusting, internal and external ballistic flows is proposed. The focus in Phase I will be developing a framework based on an existing unstructured multi-element, fully implicit, CFD code to provide an end-to-end analysis capability for interna ...

ABSTRACT: Recently quantum cascade lasers (QCLs) and interband cascade lasers (ICLs) have progressed steadily in the 3.5 10 m range with optical powers < 0.5 W. However, these devices rely on complicated band alignment and large numbers of repeating quantum wells which pose significant challenges in device fabrication. Furthermore, the sub-Watt power limitation and poor wall-plug efficiencies (W ...

Nokomis ultra-sensitive radio frequency (RF) sensor, the Hiawatha System, can leverage changes in unintended emissions signatures to monitor the overall state of electronic device health. As a device ages, emissions signatures change in a predictable and deterministic manner, enabling reliable determination of device readiness. Under this effort, Nokomis proposes to leverage hand-held embedded h ...

The MDA is in need of a robust, holistic Electronics Health Monitoring (EHM) solution that can address mission readiness concerns. Nokomis solution to this problem provides unique information to operators and maintainers and a more complete picture of component readiness. Nokomis novel methodologies for determining device health, whereby changes in unintended RF emissions signatures are leverage ...

Objectives and Intellectual Merit: The infrastructure of modern civilization is a set of complex systems1 that dynamically interact across multiple layers of abstraction. Researchers from many disciplines2 are designing analytical tools for predicting the global and local behaviors of these complicated, multi-layer networks. Easily usable, available (open source) and inter-operated tools are neede ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

There is an unmet demand for ultra-low-power, ultra-compact and low-cost radios to address emerging sensing and communication needs for military and commercial applications such as IoT/IoE. To overcome the limitations in existing bulky and power hungry radios, we propose a disruptive solution by integration of a nano-scaled THz transceiver, on-chip antenna, and energy harvesting circuits in a form ...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...

Miniaturized base metal electrodes (BME) multilayer ceramic capacitors (MLCC) are of great interest for future missile applications as designers are striving to achieve smaller, lighter, cheaper, faster and better electronic assemblies without sacrificing long-term performance. Unfortunately, screening, reliability and qualifications criteria are either not available or not standardized. In the ...
