In today's military environment ships, systems, and equipment are being asked to perform at levels not thought possible a decade ago. The intent is to improve process operations and equipment reliability, availability, and maintainability without costly upgrades. Of course, these gains must be achieved without impacting combat readiness. Downsizing is also taking its toll on operations. Loss o ...

TWO LOCAL AREA NETWORK (LAN) STANDARDS, IEEE 802.5 AND ANSI X3T9.5 FFDDI, HAVE SEEN INCREASED USE AMONG BOTH MILITARY AND INDUSTRIAL USERS ESPECIALLY FOR APPLICATIONS WHICH HAVE TIME-CRITICAL PERFORMANCE REQUIREMENTS. THESE STANDARDS ARE THE BASIS OF PROPOSED NAVY STANDARDS, DESIGNATED SAFENET-I AND SAFENET-II. IN THE EVENT OF A FAILURE, A KEY PERFORMANCE PARAMETER ESSENTIAL TO DESIGNERS OF TIME-C ...

The ultimate goal of the proposed R&D is to design, develop and validate innovative CORBA-based software security services and compatible hardware architectures which provide high assurance for multi-level secure (MLS) network applications. The proposed approach is innovative in that it is based on the emerging OMG Security Services Specification (SSS) plus a proprietary technique for maintaining ...

EACH PHASE OF THE DEVELOPMENT LIFE CYCLE IS IMPORTANT AND THE PRODUCTS OF EACH ARE ESSENTIAL FOR A SUCCESSFUL SYSTEM. HOWEVER, DEVELOPMENT TECHNIQUES AND TOOLS ARE PHASE-SPECIFIC AND DO NOT COMMUNICATE WITH ONE ANOTHER. WE BELIEVE THAT THIS IS THE CASE BECAUSE DEVELOPERS HAVE NOT YET DISCOVERED A UNIFYING CONCEPTUAL MODEL OF INFORMATION SYSTEM DEVELOPMENT CONSTRUCTS APPLICABLE TO THE WHOLE LIFE CY ...

A SYSTEM IDENTIFICATION TECHNICAL IS PROPOSED FOR NON-DESTRUCTIVE TEST TO DETECT UNBOUNDS IN LARGE BONDED COMPONENTS. THE TECHNIQUE USES THE SYSTEM'S TIME RESPONSE DATA DUE TO RANDOM INPUT EXCITATION. SYSTEM'S EIGENVALUES AND EIGENVECTORS ARE RETRIEVED FROM THE TIME RESPONSES AND USED FOR THE CONSTRUCTION OF ACCURATE SYSTEM MATHEMATICAL MODELS. SYSTEM'S CHANGE DUE TO CRACKS, VOIDS, UNBONDS BETWEEN ...

METHODS ARE DESPERATELY NEEDED TO DISCERN THE STRUCTURAL INTEGRITY OF CRITICAL COMPONENTS OF WEAPON SYSTEMS SUCH AS PRESSURE VESSEL CASES. AT THIS TIME, NO TECHNIQUE EXISTS WHICH PERMITS A GLOBAL MONITORING OF THE OPERATIONAL READINESS OF ANY STRUCTURES, INCLUDING COMPOSITE MOTOR CASES. THE RANDOMDEC PROCEDURE, WHICH IS PLANNED TO BE UTILIZED UNDER THIS PROPOSED STUDY, APPEARS TO HAVE THE CAPABILI ...

COMPOSITE EXPLOSIVE MATERIALS LIKE PLASTIC BONDED EXPLOSIVES (PBX'S) ARE CONSIDERABLY LESS SENSITIVE TO HEAT, SHOCK AND IMPACT THAN CONVENTIONAL TNT-BASED EXPLOSIVES. THE NAVY USES THESE IN MANY LOW VOLUME MUNITIONS. THEIR INTRODUCTIONN INTO HIGH USE MUNITIONS WILL PROVIDE SUBSTANTIAL SHIP/PLATFORM SURVIVABILITY IMPROVEMENTS. THESE MATERIALS ARE COMPLEX AND COSTLY TO MIX AND LOAD USING EXISTING HI ...

The LCAC Full-Mission Trainer (FMT) is providing a cost-effective tool for training LCAC operators in normal craft operation and casualty mode conditions. However, the FMT was never validated with full-scale LCAC test data. Rather, the feel of the FMT was uning coefficients in response to inputs obtained from experienced LCAC operators. The FMT training schedule combined wi ...
