ABSTRACT: The ability of plasmas to modify combustion has been known for more than 50 years. Recent advances in plasma generation technology and measurement diagnostics have led to extensive efforts to understand both the kinetics of the plasma-flame interaction and the enhancement of combustion properties such as ignition, extinction, flame speed and dynamics. Combustion Science & Engineering, ...

There is an ongoing effort to replace high activity radioactive sources that could pose a risk for use as terrorist weapons with non-radioisotope based technologies. Currently radioactive sources serve a number of critical needs including the treatment and diagnosis of disease, inspection and certification of critical mechanical structures, the sterilization of food and medical products, ...

At present, CdZnTe is considered the material of choice for efficient, room temperature gamma-radiation detection systems used for the detection and identification of radionuclides. Despite the advances in CdZnTe materials technology during the last decade, the major impediments in the progress of - ray detection technology are the low yield of device quality materials and detectors, and the limit ...

Pharad is teaming with the Applied Physics Laboratory of The Johns Hopkins University to propose and investigate the feasibility of wideband (VHF to SHF) RF-to-digital photonic link architectures with real-time digital signal processing (DSP) that can meet the stringent performance metrics of military systems. The key requirements for our wideband DSP linearized RF-to-digital photonic link include ...

ABSTRACT: Pulsed power systems are utilized in several application platforms ranging from fuel reforming to biomedical applications. While significant advances have been made in development of solid state technology based power systems, the need for faster pulse rates as well as higher voltage requirements have resulted in a need for developing novel pulse power sources capable of pulsing at freq ...

ABSTRACT: Ramjets and scramjets are the preferred propulsion platforms for flight in the supersonic (3

The US Navy faces daunting energy challenges that will further increase in severity, given the ever-increasing global demand for energy, diminishing energy supplies and demand for enhanced environmental stewardship. Navys environment foot print consists of both emissions and noise generated every day around the world. Additionally, noise is an important issue for the Navy due to the adverse effect ...

Texas Research Institute Austin, Inc. (TRI/Austin) is developing a lithium-ion battery module that will manage individual cell thermal runaways in two ways. The active management path will be to monitor the internal temperature of the cell and remove the cell from the charging/discharging circuit if anode or cathode temperatures exceed specified temperatures. Removal from the charging/discharging ...

This effort proposes to design, develop and fabricate prototype SiGe MMICs that when combined with GaN MMICs forms the basis for additional simultaneous modes and more efficiency for the C-band Radar Automatic Collision Avoidance System (RACAS). The addition of these MMICs will enable digitally controlled pulse mode interleaving and switchable and simultaneous polarizations for enhanced Coherent A ...

Many organizations have personnel performing complicated tasks at consoles. In many cases these tasks are defined by checklist procedures, complicated lists of the actions that need to be taken, as well as the readings that show the action was taken correctly. In the past, these checklists have been presented to personnel as paper documents, which have severe limitations and impose significant bu ...
