In the field of seismic event identification, three spatial dimensions and one time dimension are almost always coupled together. This may create confusion in data perception and interpretation. A novel multi-D display device wchih can improve data visualization is needed. The object of this project is to develop a Volumetric Image Display (VID) capable of displaying multi-D volumetric images in a ...

A number of imaging and target identification admit a generalized tomographic formulation where the object to be imaged (identified) is multi-dimensional and the sensor data are one-dimensional generalized projections of this object. The goal of the proposed research is to formulate, develop and test and evaluate efficient wavelet based algorithms for such applications directly at the level of the ...

FERROELECTRIC SELF-ASSEMBLED MONOLAYERS ARE BEING CREATED BY CHEMICALLY MODIFYING MONOLAYERS OF ADSORBED N-ALKANETHIOLS IN VACUUM. THE SURFACE POTENTIALS OF THE RESULTING THIN FILMS ARE MEASURED AS A FUNCTION OF TEMPERATURE AND PYROELECTRIC COEFFICIENTS AND FIGURES OF MERIT FOR THE MODIFIED FILMS DERIVED. THESE MONOLAYERS SHOULD BE EXCELLENT MATERIALS FOR ADVANCED ROOM TEMPERATURE PYROELECTRIC D ...

ANALYSIS OF THE STABLE ISOTOPES IN ATMOSPHERIC METHANE SAMPLES CAN BE USED TO IDENTIFY LOCAL SOURCES AND TO DEFINE THE GLOBAL BUDGET OF THIS RADIATIVELY IMPORTANT GREENHOUSE GAS. THE PROJECT IS DEVELOPING A PORTABLE AND LESS EXPENSIVE ALTERNATIVE TO ISOTOPE MASS SPECTROMETRY FOR MEASURING (13)CH4 AND CH3D COMPONENTS IN METHANE SAMPLES. THE METHOD IS BASED ON INFRARED ABSORPTION USING A HELIUM NE ...

N/A

Environmental monitoring of possible contamination by radioactive materials has created a need for portable measurement systems that can assay low-grade radioactive materials in waste and in process equipment. Currently available instruments for environmental radiation monitoring are either of poor spectrum resolution (NaI detector) or of limited portability (HP Ge). HP Ge detectors require large ...

THERE ARE STRONG MOTIVATIONS FOR THE DEVELOPMENT OF NEW SIGNAL, IMAGE, AND DATA PROCESSING ALGORITHMS THAT ARE WELL-MATCHED TO ATR PROBLEMS AND THUS OFFER PROMISE IN EXPLOITING THE SPECIFIC SPATIO-TEMPORAL CHARACTERISTICS THAT DISTINGUISH TARGETS OF INTEREST FROM ENVIRONMENTAL CLUTTER. IN THIS PROPOSAL WE DESCRIBE AN EFFORT AIMED AT ACCOMPLISHING THIS TASK BY EXPLOITING THE RECENT ADVANCES IN WAVE ...

THE PROGRAM IS DIRECTED TOWARDS THE DEVELOPMENT OF A PLANAR, LOW TEMPERATURE (650C), INTERNALLY REFORMING SOLID OXIDE FUEL CELL (SOFC) POWER SUPPLY THAT WILL LEAD TO THE POWER PLANT HAVING A POWER DENSITY EQUIVALENT TO A MODERN GAS TURBINE AND AN EFFICIENCY OVER 65 PERCENT. THE CELL DESIGN IS BASED ON REACTIVE MAGNETRON SPUTTERED METALS, OXIDE CONDUCTING ELECTROLYTES, AND CERMET ELECTRODES. FEAS ...
