ABSTRACT: Thermal management has become a critical factor in designing the next generation of microprocessors. The current technology is unable to meet the increasing demands. Carbon nanotubes (CNT) have excellent heat transport; however, the heat transport across the interface continues to be a challenging hurdle. Here, we have drawn a connection between heat transfer, electronic conduction, ...

ABSTRACT: The goal of this program is to develop an atom chip with a dual integrated and miniaturized optical and electromagnetic capability. We intend to develop a compact atom-chip-based system capable of producing and optically controlling and monitoring ultracold atoms with substantial reduction in complexity, size, weight and power consumption over the present state of the art. As part of ...

ABSTRACT: This Small Business Technology Transfer Phase I project will address the problem of obtaining low-defect-density gallium nitride single crystals for substrates to enable low-defect, high-performance epitaxial growth. Gallium nitride is a very promising material for numerous applications including surface acoustic wave devices, high-powered LEDs, UV diode lasers and high-powered RF devic ...

ABSTRACT: Availability of high quality, large area gallium nitride (GaN) single crystal substrates is one of the most outstanding issues for III-V nitride materials. Today's GaN device processes typically employ HVPE grown on sapphire and silicon carbide substrates, requiring elaborate buffer layers and deposition techniques to overcome lattice mismatch and dislocation densities up to 109/cm ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: Airborne directed energy weapons offer advantages over conventional weapons as they minimize collateral damage, reducing the cost of post-conflict reconstruction. However, the high power levels required by these weapons present size and weight challenges for airborne applications. In particular, the current capacity required of the power transmission cables can make them one of the heav ...

ABSTRACT: This STTR proposal is the natural consequence of our collaboration that makes use of the established know-how under the MURI program, the established track record of RHK in commercialization of critical hardware, software and electronic controllers to implement scanning probe microscopy with nanometer scale resolution of structural, electrical and optical materials properties for more t ...

Thermoelectric generators (TEGs) offer the potential for simple and efficient conversion of heat directly to electricity. However, efficient power conversion systems that incorporate TEGs present an engineering challenge, requiring an overall system design that balances critical trade-offs between TEG performance requirements, thermal management, combustion efficiency, and power conditioning. We ...

As part of this SBIR project our firm will combine algorithmic information theory with deterministic and stochastic optimization techniques to create an optimization co-processor for wireless nodes. We will focus on the problem of change-point detection in resource-constrained wireless sensor networks to realize an effective solution. We are specifically targeting Android operating system (OS) ...

We propose the development of an architecture for cognitive radio networks (CRN) to provide robust operation in jamming environments. The cold re-start problem is addressed through an innovative signaling framework, and an adaptive transmission approach is applied for mitigating various levels of jamming. Finally, cross-layer optimization methods are presented in order to optimize the performanc ...
