Abstract:THERE IS A MAJOR ARMY REQUIREMENT FOR REDUCING THE PHYSICAL SIZE OF TACTICAL HF ANTENNAS (FOR USE ON A VARIETY OF CARRIERS FROM TRACKED VEHICLES TO DRONES) FOR ELECTRONIC WARFARE APPLICATIONS WITHOUT DEGRADING CURRENTLY ACCEPTED PERFORMANCE AND STILL MAINTAINING THE SAME GAIN, FREQUENCY AND POWER… more
Abstract:MUCH OF THE RESEARCH ON OUTSTANDING PROBLEMS IN METEOROLOGY AND CLIMATE DYNAMICS WOULD PROFIT GREATLY FROM THE AVAILABILITY OF INEXPENSIVE IN-SITU MEASUREMENTS OF THE ATMOSPHERE. THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH (NCAR) HAS DEVELOPED A FAMILY OF LIGHTWEIGHT DIGITAL DROPWINDSONDES, AND… more
Abstract:PROJECT OBJECTIVES: THE PRIMARY OBJECTIVE OF THIS EFFORT WILL BE THE DEVELOPMENT OF A COST METHODOLOGY FOR PREMILESTONE I PLANNING FOR EMERGINING TECHNOLOGY WEAPONS SYSTEMS/SUBSYSTEMS. THE PROPOSED EFFORT ALSO ADDRESSES COST RELATED ACTIVITIES FOR PROGRESSION THROUGH PREMILESTONE 0 AND PHASE 0… more
Abstract:1Hull-mounted sonar sensors are subjected to a number of shipborne noise phenomena due to coupling through their mechanical mounts. Such noise is complex, composed primarily of engine noise, wave induced hull vibrations, and other hydrodynamic pressure-induced noise due to propeller cavitation and… more
Abstract:SENSITIVITIES IN MAGNETIC AND LOW-FREQUENCY ELECTROMAGNETIC BANDS HAVE BEEN LIMITED BY AMBIENT NOISE. SENSORS ARE AVAILABLE WITH EXTREMELY LOW NOISE LEVELS (ABOUT FIVE ORDERS OF MAGNITUDELOWER THAN THE AMBIENT NOISE). WE PROPOSE TO USE SUCH SENSORS IN AN ARRAY CONFIGURATION WHERE IT IS POSSIBLE TO… more
Abstract:A BREAKTHROUGH IN ENGINEERING OPTIMIZATION METHODOLOGY HAS BEEN ACHIEVED, BASED ON TECHNOLOGY DEVELOPED IN THE DARPA INITIATIVE IN CONCURRENT ENGINEERING (DICE) PROGRAM. THE METHODOLOGY IS BASED ON A COMPLETELY RIGOROUS INTEGRATION OF UNCERTAINTY AND RANDOMNESS IN ENGINEERING OPTIMIZATION PROBLEMS.… more
Abstract:Chaotic signal processing techniques treat signals as geometric objects in a multidimension state space. We have developed a processor for chaotic signals that incorporates several novel ideas. We propose to use this processor to analyze real signals and use the results as a starting place to… more
Abstract:THIS STUDY WILL EVALUATE A TOUCH SCREEN PATIENT-INITIATED COMPUTER SYSTEM DESIGNED TO INTEGRATE CANCER AND OTHER ADULT PREVENTIVE SERVICES INTO THE PRIMARY CARE ENVIRONMENT. THE COMPUTER SYSTEM, NAMED HEALTH TOUCH, WAS PREVIOUSLY DEVELOPED BY A WORKING GROUP OPERATING FROM THE DEPARTENT OF FAMILY… more
Abstract:THIS PROJECT USES A FEASIBILITY STUDY TO DETERMINE IF CURRENTLY AVAILABLE EXPERT SYSTEMS SOFTWARE FOR MICROCOMPUTERS ARE CAPABLE OF DETERMINING AND COMPLETING MEDICAL REVIEW PROCEDURES CURRENTLY PERFORMED AT 3 LEVELS BYHCFA INTERMEDIARIES. SECONDLY, THEY WILL BUILD A PROTOTYPE TO HANDLE THE… more
Abstract:THE OBJECTIVE OF CCR'S PHASE I EFFORT IS TO PERFORM AN IN-DEPTH SURVEY OF RELEVANT ARCHITECTURAL DATA, TO IDENTIFY VIABLE APPROACHES AND SOLUTIONS, AND TO DEVELOP THE DESIGN FOR A PROTOTYPE MODELING AND SIMULATION TOOLSET TO ASSIST IN THE EVALUATION OF SMALL EHF COMMUNICATIONS ARCHITECTURES.… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
