Project objectives briefly described: i. Improve accuracy of measurement for cheating examinees by using a scoring method that takes account of the credibility of the examinee's patterm of wrong answers. ii. Provide an adjunct to on-line calibration that would assist in timing the replacement of items. iii. Identify test sites and recruiters that are associated with high rates of item compromis ...

Many areas of military and civilian work are becoming increasingly complex and non-routine. Cognitive Flexibility Theory is a unique approach to instruction that prepares people to effectively deal with such challenges. For critical elements of Navy training, complex content domains will be identified that are characterized both by complexity and difficulty in achieving training success. The pa ...

Experience during the Gulf War demonstrated the need for a secondary sensor for the HARM anti-radar missile. Benefits of adding an appropriate secondary sensor include: mission completion after defense countermesures, increased probability of kill and reduced probability of fratricide. A HARM missile enhancement would be aimpoint select capability from the secondary sensor. A Phase I program i ...

The proposed research effort will provide a new and improved numerical technique for predicting dynamic structural failure. The technique is based on the use of an innovative numerical technique referred to as Element Free Galerkin (EFG) or "gridless" technique developed by Professor Ted Belytschko at Northwestern University. The method will be introduced in, the general purpose codes for struct ...

Nanoscale powders with narrow particle-size distributions significantly reduce sintering time and temperature during the processing of high performance coatings and structural ceramics; their superplastic behavior can be exploited to net-shape form structures. Nanoscale powders can be made by a variety of methods but production scale, cost effective, environmentally sound methods are required. A s ...

Today\'s submarine towed array handling system operating parameters an methods are equivalent to those used in the late sixties. Attempts to utilize conventional cable handling methods are not suitable for array handling, and appropriate methods have not yet been defined. Outboard system volume, weight, system complexity, installation complexity, and cost far exceed acceptable standards for a hand ...

THE FEASIBILITY STUDY WILL BE IN EIGHT ELEMENTS WITH ELEMENT 1 BEING AN ANALYSIS OF CURRENT TRANSPORTATON PLANNING AND ENGINEERING SOFTWARE AND HARDWARE USE. DESIGN-COMPUTERS WILL BE IDENTIFIED IN THIS ELEMENT. IN ELEMENT 2, AN ANALYSIS OF DATA INPUT OPTIONS AND THEIR IMPLICATIONS FOR THE SOFTWARE AND DESIGN-COMPUTER HARDWARE IDENTIFIED WILL BE COMPLETED. THE REQUIREMENTS TO ACCOMODATE AUTOMATIC V ...

PAVEMENT DISTRESS DATA ARE UTILIZED DURING PAVEMENT EVALUATION, DESIGN, REHABILITATION, MAINTENANCE, MANAGEMENT, AND RESEARCH. CURRENTLY, THE MANUAL SURVEY METHOD, UTILIZING PAPER AND PENCIL, IS USED EXTENSIVELY IN COLLECTING THE DISTRESS DATA, BUT THIS PROCESS IS SLOW, TEDIOUS, EXPENSIVE, AND PRONE TO HUMAN ERROR. THE OBJECTIVE OF THIS RESEARCH IS TO DEVELOP A COMPUTERIZED PAVEMENT DISTRESS DATA ...
