Ultrasound is a therapeutic modality which has been used clinically for 60 years, but has been limited in practice by the complexity of the technology. Recent research has allowed for the development of a portable, wearable, long duration, low intensity therapeutic ultrasound system. The system is powered by battery, and can be applied by a user to deliver up

Establish a radiation-aware analysis capability in a commercial EDA design flow that will enable first-pass success in radiation-hardened by design (RHBD) for DoD ASICs in much the same way that existing EDA design suites ensure first pass functionality and performance success of complex ASICs destined for commercial applications. Layout-aware, calibrated single-event radiation models that captur ...

State of the art yttria stabilized zirconia (YSZ) based thermal barrier coatings (TBCs) are typically limited to maximum use temperatures of 1200-1300C. A thermal barrier coating (TBC) with a 1500C temperature capability would be a major gas turbine materials breakthrough. New coatings with a 200C temperature advantage can be used by the gas turbine industry to significantly increase turbine effi ...

Achieving a systems-level understanding of science associated with climate change is a key topic within the DOE mission. Light absorbing particles are an important atmospheric constituent and have a direct impact on climate. They also impact air quality and health and human activities play a major role in their abundance and distribution. There is a critical need for improved observational capacit ...

There is widespread concern regarding carbon emissions from fossil fuels, resulting in a drive towards improved efficiency in reactor (boiler) performance while reducing carbon emissions. Coal will continue to be a primary source of energy for economic growth for the foreseeable future, thus there is a push to reduce net carbon emissions of coal operated plants by replacing part of the coal with b ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

The US DoD requires robust ways of neutralizing threats posed by hostile powers and terrorist organizations that may be in possession of dangerous weapons of mass destruction (WMDs). Unfortunately, the weapons currently available to the DoD do not offer a way for the WMD to be destroyed without risking the spread of that material throughout the area. The strategy for the defeat of biological weapo ...

Lean-burn gasoline engines have difficulty reliably igniting fuel mixtures at sufficiently high air to fuel ratios. Common ignition systems are based on a spark gap driven by a pulse transformer ignition coil). Unfortunately, these systems have small plasma excitation areas, are slow, wear down the spark plug electrodes, and are not suitable for high pressure engines. The use of transient plasma i ...

The increased accessibility via remote login, along with steadily growing numbers of HPC users and projects, poses a challenging question for HPC system management: How to secure HPC systems and protect the data inside these systems? There are several challenging issues that prevent the direct deployment of existing personal computer or cloud security tools in HPC systems: 1) The overhead introduc ...
