The objective of the proposed project is to develop designs for manufacturable all-metal terminal hot-electron transistors (AMTHETs) that will enable 1W – 10W THz RF amplifiers and oscillators. The proposed work will focus on quantum-mechanical modelin...

A challenge for Artificial Intelligence recommenders is explaining their reasoning to users. Humans tend to explain concepts with symbolic narratives, which contrasts the way non-symbolic machine learning represents concepts. This research addresses this challenge by grounding the research in the problem of helping transitioning veterans find relevant careers. The developed prototype will provide ...

There are many challenges with sustainment of long term supply chain of electronics parts necessary to ongoing support of fielded defense vehicles.One such example is the keyboard power supply installed on the Naval Landing Craft Air Cushion (LCAC) vehicle. These supplies are no longer readily available and the Defense Logistics Agency (DLA) has need for an alternate supplier that can qualify as a ...

Methods for interconversion between cell types (cellular reprogramming) are currently discovered through resource intensive trial and error. Experiments may test a multitude of transcription factors to identify correct combinations that influence cell fate. In addition, reprogramming approaches commonly use stem cell intermediates such as induced pluripotent stem cells (iPSCs), which are generated ...

This effort will analyze publicly available online communication data, uniquely applying empirical results from the cognitive bias literature, to quantify the impact of cognitive biases on exposure to, use of, and propagation of online information. SoarTech, with its partners, will develop and evaluate methods to identify and measure cognitive biases in online information environments. The team wi ...

High-speed flight vehicles commonly use carbon / carbon (C/C) and carbon / silicon carbide (C/SiC) for structural components. These materials are chosen because of their superior structural properties at elevated temperatures. Most often, their properties are characterized using flat and thin material test plates. While this approach is convenient, it is not guaranteed to yield material properties ...

Ultran will develop and prototype the transducer technology and initial system prototypes for a wearable system for imaging and modulation of peripheral nerves. Transducers developed for energy delivery will use Ultran's gas matrix piezoelectric (GMP) technology while those for imaging may use either GMP and piezoelectric micromachined ultrasonic transducers prototyped by a supplier. Miniaturized ...

Wearable, high image quality, low power, conformable ultrasound capable of delivering acoustic energy for nerve modulation

X-Bow Launch Systems and its partners have developed a feasible concept to additively manufacture solid propellant. This additive manufacturing method, adapted from existing scaleable processes, will reduce the lifecycle cost and improve the overall responsiveness of the X-Bow Launch Systems vehicle. The innovation is to adapt breakthrough manufacturing processes developed for the Li-Ion battery i ...

The In Process Control for L-PBF (IPCL) program leverages and in process inspection method recently developed and successfully demonstrated for NASA. This Layer Topographic Map or LTM method measures the surface if every melt layer using a commercial laser profilometer. LTM software detects, locates and identifies flawed regions within a layer for every layer in the part. It does so for several co ...
