ABSTRACT:Significant gains to engine performance are achievable through the development of advanced cooling designs in blade and vane airfoils in order to allow higher turbine inlet temperatures. Correspondingly, reductions in maintenance costs can be achieved through higher confidence evaluation criteria for such cooling designs. In this effort, scaling parameters used between experimental and en ...

LIGHT SCATTERED FROM CLEAN SEMICONDUCTOR WAFERS IS DUE TO BOTH SURFACE AND SUBSURFACE DEFECTS. SCATTER FROM SURFACE DEFECTS GENERALLY DOMINATES BY AN ORDER OF MAGNITUDE OR TWO. A METHOD TO SEPARATE SUBSURFACE SCATTER FROM SURFACE SCATTER HAS BEEN FOUND, AND IT IS PROPOSED HERE TO UTILIZE THAT TECHNIQUE TO INDICATE THE LOCATION AND AMPLITUDE OF SUBSURFACE DEFECTS BY COLOR MAPPING THE LOCATION AND I ...

SPECIAL SIGNAL PROCESSING TECHNIQUES APPENDED ON TO REMOTE SENSING CAPABILITIES ARE DESCRIBED FOR "PEEKING" INSIDE "TEL" CARGOS.

ABSTRACT:The advent of wide area Ground Moving Target Indication (GMTI) and Overhead Persistent InfraRed (OPIR) systems V particularly those with broad area coverage and staring focal planes V heightened the call for persistent surveillance for DoD and intelligence community (IC) missions. Persistence allows warfighters to monitor areas of interest and catch fleeting events of tactical importance, ...

ABSTRACT:To meet the Air Force's need for cyber defense and hardening of tactical IP networks, we propose developing Cyber Hardening and Agility Technologies for Tactical IP Networks (CHATTIN). CHATTIN will harden existing tactical networks by injecting an authentication mechanism, automatically detect and block attacks and reconnaissance attempts, and provide agile isolation of adversarial nodes. ...

ABSTRACT:The objective of this proposal is to develop and demonstrate an innovative laser cavity design based on high efficiency diffractive optical elements (DOEs) to replace currently used external bulk laser optics. This innovation will improve the stability of Vertical External Cavity Surface Emitting Laser (VECSEL) systems as well as other types of solid state laser systems. The developed DOE ...

For this Phase II SBIR, Princeton Lightwave Inc. (PLI) is proposing to demonstrate disruptive single photon counting performance characteristics of Geiger-mode avalanche photodiode (GmAPD) cameras by making dramatic improvements to existing commercial short wave infrared GmAPD focal plane arrays. These cameras provide high-performance three-dimensional imaging capability for intelligence, surveil ...

A NEW DESIGN CONCEPT FOR ELECTRONIC SHELTERS USING SOME OF THE ADVANCED MATERIALS SUCH AS CONDUCTIVE COMPOSITES, AND REINFORCED CONDUCTIVE SILICONE FABRICS WILL BE TESTED. THE MOST RELEVENT APPLICATION PARAMETERS SUCH AS CONDUCTIVITY OF THE COMPOSITES AND FABRICS, THE JOINING MECHANISM TO ENSURE ELECTROMAGNETIC COMPATIBILITY, THE FLEXIBILITY, THE TRANSPORTABILITY AND TOTAL SYSTEM WEIGHT WILL BE AD ...

ABSTRACT: In this proposal, the MaXentric team outlines its strategy for creating a Radar-based Compressive Sensing and Target Classification system, code-named Rad-CSC. In this Phase I, the team will implement and optimize compressive sensing and classification algorithms for use with conventional and synthetic aperture radar data. Data will be chosen from publicly available datasets, such as the ...

THE VAPOR SPACE INSIDE AN AIRCRAFT FUEL TANK EITHER IS OR IS NOT FLAMMABLE (OR EXPLOSIVE) DEPENDING UPON THE PERCENTAGE OF FUEL VAPOR AND OF OXYGEN OF INERT GAS SUCH AS NITROGEN OR CARBON DIOXIDE. IT IS IMPORTANT TO KNOW THESE PERCENTAGES WHEN TESTING THE EFFICACY OF EXPERIMENTAL INERTING MEASURES BY FIRING LIVE ROUNDS AT TEST TANKS; BUT THERE IS NO FAST, CONVENIENT, FIELD METHOD OF MEASURING THE ...
