Award Data

Megapixel-class imaging systems with single-photon sensitivity, high time resolution (sub-ns), and the capabilities to detect and process photons at high rates (above 108 detected photons per second) are highly desirable for a number of DOE, homeland security, national defense, and nuclear medicine applications. The event timing resolution largely depends on the specific application, but can rang ...

SiPMs have received significant investigation over recent years, because they offer potential as a solid-state single- photon-sensitive alternative to photomultipliers (PMTs), but their performance does not meet the needs of science, and there are no commercial fabs capable of manufacturing them at low cost. An important feature of SiPM technology is that it is possible to integrate the electron ...

In the tactical wireless ad hoc network, all networking nodes are vulnerable to various security attacks. Therefore, the centralized data storage is unable to protect the tactical data once the storage device is compromised by an adversary. Distributed data storage is the alternative that the data are securely and reliably spread on the networking nodes with certain redundancy, offering high data ...

The goal of this Phase I project is to develop an engineering plan and to create a prototype for a mobile, cloud-based expert system to aid in diagnosis, decision support and predictive analytics to improve clinical outcomes for veterans, soldiers, and their families with traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). Lifecom, Inc. is a health information technology compan ...

Inspired Light is developing a high-efficiency Concentrating Photovoltaic (CPV) system that requires accurate, 2-axis tracking. Available tracking systems are too large, expensive and require specialized setup procedures that are incompatible with a very low cost, versatile deployment strategy. This project will develop and demonstrate feasibility of a self-configuring solar tracking mechanism an ...

Electric vehicles, including hybrids in the nearer term, are the principal transportation technology by which the United States can become independent of foreign oil, can become energy independent overall, and can effect control over greenhouse emissions. For this to become reality, electric vehicle costs need to come down and performance needs to go up. For electric vehicle motors, the goals are ...

The modeling and simulation of human performance is often difficult because there is no uniform framework for expressing the content and structure of a human performance model and all but impossible to compare and contrast across different models despite the abundance of quantitative modeling tools. The inability to communicate model structure and content is not just a practical shortcoming; it is ...

Intelligent tutoring systems (ITS) are complex adaptive learning systems that simulate one-on-one tutoring. Research shows they improve learning and reduce time to mastery. Unfortunately, they are also expensive and time-consuming to produce. Existing IT authoring tools eliminate low level programming but require that domain models, expert models and content be created manually. In Phase I of t ...

This proposal outlines a project aimed at providing a radical improvement in ion source technology that can be applied to the mass spectrometric analysis of actinides. The state-of-the-art secondary ion mass spectrometers (SIMS) employ the duoplasmatron ion source to create the primary ion beam for actinide analysis. The duoplasmatron only has sufficient brightness and a small enough energy spre ...

Novel, inline measurement techniques are needed to improve the quality and performance of new solar cells. Manufacturers today measure cell performance inline under white light conditions, but are unable to obtain the cell response as a function of wavelength without extensive offline testing. They are also unable to extract detailed spatial maps of full-spectrum spectral response. This informatio ...
