Corvid Technologies is pleased to offer this proposal for the development of a first-principles numerical approach to modeling Solid Rocket Motor (SRMs) response to unplanned thermal stimuli. Corvid has a history of developing models for propellant violent reaction to projectile and fragment impact stimuli. We will adapt an existing heat transfer model to address SRM fast and slow cook-off due to ...

This project addresses the problem of the wireless transfer of power between a source and nearby mobile platform such as a robotic vehicle. The primary objective of this research will be to design and evaluate, by analysis and computer modeling, an inductively-coupled system consisting of an optimally-designed configuration of transmitting coils to maximize the coupling efficiency though a target ...

Kyma Technologies will explore aspects of seeded bulk GaN crystal growth to develop manufacturing processes for large area, high quality, semi-insulating GaN substrates for RF applications. Preparation of GaN seeds and growth thereon, including surface cleaning, off-cut angle and direction, growth initiation, and defect control will be investigated. The use of novel seeds and growth conditions wil ...

Kyma Technologies proposes a research and development effort to fabricate and test GaN-based FETs on GaN and SiC substrates. AlGaN/GaN HEMT structures will be tested to identify the impact of defects on the thermal characteristics and degradation behavior in the devices in order to improve device performance and reliability. Thermal models of GaN-based FETs on GaN substrates with comparisons to Si ...

The overall objective of this Phase II effort is to implement a HVPE crystal growth tool for large diameter GaN crystals suitable for 4" diameter substrates. Using this new crystal growth platform, Kyma will optimize its design and operation to develop a manufacturing process for growing high quality, low defect density semi-insulating GaN substrates. CFD modeling will be used extensively to ident ...

There is a need for a simple, affordable method for measuring domoic acid in the field. This project will develop a rapid, onsite kit for domoic acid featuring a filter membrane that produces a readable color response without need for instrumentation. The filter membrane contains three or more zones with different assay characteristics in close proximity. These zones will indicate different co ...

MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE TRANSFORMATIONS APPLIED IN THE COMPILATION OF A GIVEN PROGRAM. THE COMPILATION CHECKER WILL VALIDAT ...

PLEX Corporation will demonstrate a highly efficient laser emitting light at 1100nm in the near infrared. Technical issues in laser design will be resolved in Phase I, with a full lasing test experiment in Phase 2. This laser candidate has potentially a 25% electrical efficiency and can, in principle, be scaled to high power levels. Cutting and welding applications are foreseen in the industrial e ...
