The goal of this proposed DARPA SBIR project is to design, build and test a high efficiency 2 cycle ceramic/polymer engine that will run on JP-8 fuel with a self-contained onboard starter generator. The engine system will ncorporate a ceramic piston,cylinder, and head with lightweight polymer engine casing. The use of high wear thermally insulating ceramics will greatly eliminate the need for lu ...

Improving the quality and intensity of the x-ray beam is an important design goal for every synchrotron installation. Although small, the effects of vacuum windows on x-ray absorption and phase contrast cannot be neglected. Synchrotron x-rays have wavelengths on the order of one Angstrom (1 x 10-10m), the same order of magnitude as inter-atomic distances. These x-rays are used to study many differ ...

How can one make a sensor that can make different types of measurements on a large area, on a shape that is not known a priori, that is lightweight, that is accurate with a fine resolution, while at the same time has the resolution and sensitivity of astand-alone instrument, and at an affordable cost?'This proposal will develop a process and a tool to answer this commonly asked question in militar ...

Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...

Theoretical research on asynchronous circuits has provided top﷓down methods that start from an operational description of a circuit. Top-down methods avoid the difficulty of understanding (let alone verifying) the behavior of compositions ofasynchronous components. In practice, however, design begins from a functional decomposition, often incorporating components previously designed. ATC-NY w ...

Sophisticated attacks on computer systems typically proceed in stages. The attacker first probes the target site to discover its vulnerabilities, and then exploits the vulnerabilities. To avoid detection, attacks can be spread out over time or be launchedfrom multiple hosts. An attacker who has gained entry to a network host can use it as a base from which to attack other hosts on the network. Cur ...

Monte Carlo simulations of rarefied gas dynamics are important for many applications. This project aims to substantially accelerate Monte Carlo (MC) algorithms and develop a rigorous and efficient computer code applicable for a wide range of Knudsen numberfrom rarefied to continuum flow regimes. This will be achieved by using implicit treatment of the collision processes, majorant frequency scheme ...

The proposed effort addresses the important need to develop an efficient direct emission source in the 555-585 nm (deep-green) wavelength range, corresponding to the peak photopic response of the human eye. Current limitations in extending the operatingwavelengths of III-N devices beyond the blue-green region of the spectrum are overcome by combining the quantum dot approach, in which a red shift ...
