In today's cost-constrained environment, acquisition reform is a critical component in the design, production and support of modern warships. This reform includes policies that require system acquisition programs to pursue commercial management and systems engineering practices. The application of Integrated Product and Process Development (IPPD), concurrent engineering, open systems architectu...

The Virtual Test Bed (VTB) is a software environment that supports design, analysis, and virtual prototyping of electric power systems, with an emphasis on naval applications. This paper describes the status of development of the VTB and its use in the multi-technical field of ship power systems.

This paper describes the Virtual Test Bed (VTB) which is a software environment that is being developed for design, analysis, and virtual prototyping of large-scale multitechnical physical systems with emphasis on Naval electrical systems [1]. Motion control applications and the applicability of several different simulation environments are discussed.

This paper is a revised version of part of a previous report (Give'on, 1962) which was prepared for the U. S. Office of Naval Rsearch, Information Systems Branch, under contract No. 62558-2214, at the Applied Logic Branch of the Hebrew University in Jerusalem, Israel (February 1962). This revision was done for the U. S. Office of Naval Research, Information Systems Branch, under contract No. No...

As software control of time-critical functions in embedded systems becomes more common, a means for the precise specification of their behavior and formal methods for analyzing system requirements becomes increasingly important. Modechart is a graphical specification language introduced to meet this need. The main focus of paper is on methods and supporting tools for representing and reasoning ...

The Mapping, Charting and Geodesy Branch of the Naval Research Laboratory at Stennis Space Center, Mississippi. is conducting a multi-year program for the development of unmanned, untethered sensor systems for the collection of tactical oceanographic data in littoral regions. The primary function of this program is the development of immediate force-multiplying survey capabilities for the colle...
