BOLD, NTBOURETTE, APDr. Norbert T. Bold graduated from Marquette University and later received his M.S. and Ph.D. degrees in Electrical Engineering from Northwestern University. He served three years as a Naval Engineering Officer aboard an Aircraft Carrier and a Minesweeper and has nineteen years technical experience in shipboard navigation
underwater target and SDMS projects for the Navy. He is currently a Program Manager in the Autonetics Marine Systems Division Rockwell International where his primary assignment is the development of advanced concepts and applications of SDMS to Navy programs. He has published several technical papers. was elected to four Scholastic Honorary Societies and was the recipient of a NROTC Scholarship. Mr. A.P. Bourette
Manager Systems Applications Autonetics Marine Systems Division. received his B.S. degree in Mathematical Physics from Long Beach State University. He began his career with a Computer Analysis Unit. performing tasks related to computer application. programming and interfacing. He has made significant contributions to the Central Computer Complex approach adopted for the SSN-688 Combat System and has performed inertial systems engineering efforts on the MK2 SINS for the POSEIDON Program. He spent some time in the Washington D.C. area providing technical expertise to various Navy organizations. Upon his return he soon was selected to manage the Systems Applications organization at Rockwell International. This organization is primarily responsible for the Shipboard Application of SDMS. He has directed several application studies showing the significant advantages associated with multiplexing. Recently. he provided the technical direction for the FY80 SSN SDMS Preliminary Design Phase.

Rockwell International is currently under Navy contract to fabricate the engineering Development Model (EDM) of the Shipboard Data Multiplex System (SDMS) for general data transfer aboard surface ships and submarines. The application of SDMS significantly reduces hardware such as cables, switchboards, and Signal Data Converters (SDC), and it provides the capability to add many desired features which are currently not practicable. In applying SDMS to a specific ship, a massive amount of signal data must be considered. The Application Design Automation program.(ADAP) is a set of computerprogram. that have been developed to accomplish this task. ADAP com bines signal population data, ships configuration data, and SDMS hardware characteristics to produce an SDMS configuration layout together with documentation necessary to analyze, evaluate, and implement the system. Specific outputs include hardware requirements, system layout, and interface requirements including wire list information. The Timing, Event and Load Simulation (TELS) program.simulates SDMS and provides performance data (system capacity, throughput rate, transport delays) for any system configuration. Conventional SDCs can be elimianted from Navy shipboard systems when SDMS is used. SDMS provides the necessary data distribution, signal conversion, and computer interface. In addition, many functions of the conventional switchboards can be performed within SDMS, thus reducing the size or eliminating conventional switchboards. Very small switch-bomb will provide the necessary control of data distribution. With SDMS, an automatic and continuous Noise and Vibration Monitoring (NVM) capability is readily available. The automated NVM function will enhance the safety, operation, and maintenance of the ship. Problems with machinery or excessive self-noise generation will be detected much sooner, and corrective action implemented on a timely basis.

This paper presents the results of one phase of a study concerning methods for addition of P>;2 numbers, each encoded as a vector of digits (digit vector) of length N. Such multi-operand addition has been studied most often in the context of reducing a set of partial products to a single result in the implementation of multiplication. More generalized multi-operand addition, most notably in the form of inner product calculations is, however, central to numerous scientific applications of digital computers. Although multi-operand addition is trivially accomplished by accumulation (iteration in time) in any general purpose machine, demands for very high-speed computation, typified by 2- and 3-D signal processing prompt implementation of dedicated, hardware-intensive structures for multi-operand addition. This study, for example, is motivated in part by requirements for rapid simultaneous addition of up to 100, 16-bit operands in the design of a dedicated processor for real-time reconstruction of 3-D images of the beating heart and breathing lungs [1].

This paper describes a series of experiments designed to examine the antenna characteristics of probes which are used as detectors in ion-acoustic wave experiments. Reception patterns are measured which are in qualitative agreement with theoretical predictions. The near-field antenna pattern of the wave-launching grid is found to be important.

A description will be given of a process consisting of two connected vertical stand-pipes. This physical process is rather simple in the details of its construction, but the relationship between the flows into and out of the standpipes and the levels is nonlinear and complicated. A nonlinear mathematical model will be derived to describe the dynamical behaviour of this system. A control structure with nonlinear multi loop feedforward and linear single loop feedback control will be analyzed and discussed. Simulation and implementation with an experimental laboratory set-up are used to illustrate and demonstrate the behaviour of process with the proposed control structure.
