Studies on damage aggregation for weapons salvos
(Monterey, California. Naval Postgraduate School, 1990-07) Esary, James Daniel; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS); Operations Research
This document records three working studies from an ongoing investigation of models and methods for the prediction of the cumulative effect of weapons salvos. The first paper is about an extant formula for estimating the expected proportion of damage to an area target, which proves to be optimistic when compared to a plausible model for the effect of the salvo. The second paper describes an alternate formula which is conservative when compared to the same model. The third paper describes a basic case of an emerging family of target configuration and weapons impact scenarios which lead to the plausible model
A theorem on the optimal allocation of effort
(Monterey, California. Naval Postgraduate School, 1984-10) Owen, Guillermo; Grofman, Bernard; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
A limited time budget is to be allocated to learning several tasks, so as to maximize the probability that a majority of these tasks will be performed correctly. It is shown that in the symmetric linear case, it is optimal to allocate time equally among k of the tasks, where k is at least a majority, but may be more, depending on the actual time available. In particular, time is allocated to all tasks if there is not much time available, but to only a majority of the tasks if the available amount of time is reasonably great.
Golden Anniversary - Fifty years of graduate education in operations research at NPS produces 3,300 alumni worldwide
(2001-02) Schrady, David; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS); Operations Research (OR)
The year 2001 marks the 50th anniversary of the graduate education program in operations research at the Naval Postgraduate School in Monterey, Calif. It was no accident that the School should have begun its program so early. The U.S. Navy established the first formal operations research organization in this country in the spring of 1942 and relied on operations research throughout World War II. In 1950, the Chief of Naval Operations directed that a program of study in operations research be created. The program began in August of 1951 with a class of nine students, and the first degrees were awarded in January 1953. The curriculum has been offered continuously since its initiation. There are more than 3,300 alumni representing all of the U.S. military services and those of 31 other nations.

Design considerations for the NPS signal processing and display laboratory multiprocessing operating system
(Monterey, California. Naval Postgraduate School, 1975-11) Allen, Belton Earl; Barksdale, Gerald Leonard; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
The design and implementation of MUNIX, a tightly-coupled symmetric multiprocessing PDP 11 based operating system providing real-time, interactive, and background processing facilities in a hierarchical memory environment is described. MUNIX is a variant of UNIX, an operating system for the PDP 11 developed at Bell Laboratories. The three major design goals of the system were: (1) support for processes capable of real-time interaction with several dynamic graphics display units, an array processor, and a multi-channel A/D converter ; (2) interactive and background processing facilities to support program development; and, (3) management of the hierarchical storage created by the mix of shared and private memories of various speeds. The resulting MUNIX system provides an effective mechanism for resource sharing in a laboratory environment and is the basis for protected real-time operation in a multi-user system. (Author)
Doctors on ships?
(Monterey, California. Naval Postgraduate School, 1972-09) Gaver, Donald Paul; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
The decision as to whether a medical doctor, or other expensive specialist, should be carried aboard ship depends upon demand for service, consequences of not providing this service, and cost of providing the service. A simple preliminary mathematical model to aid in making this decison wisely is presented. (Author)
Effects of ambient turbulence and stratification on the demise of trailing vortices
(Monterey, California. Naval Postgraduate School, 1986-07-11) Sarpkaya, Turgut; Daly, John J.; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
A series of experiments was carried out with two streamlined foils at two different speeds in a towing tank. The ambient turbulence (nearly isotropic) was generated by means of a biplanar grid. The model-grid separation distance was varied systematically in order to subject the trailing vortices to varying degrees of turbulence. The data have been expressed in terms of a normalized turbulence parameter and the relative rise of the vortices. The results have shown that the ultimate height to which the vortices rise prior to their demise is controlled by the two parameters cited, irrespective of the shape and the aspect ratio of the lifting surfaces. A numerical analysis has been initiated to analyze the motion of the trailing vortices and the propagation of internal waves in density stratified medium with the ultimate objective of incorporating the effect of turbulence into the numerical model.
An implicit/explicit approach to multiobjective optimization with an application to forest management planning
(Monterey, California. Naval Postgraduate School, 1986-06) Harrison, Terry P.; Rosenthal, Richard E.; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
Implicit utility/value maximization and explicit utility/value maximization are identified as two major classes of multiobjective optimization methods. The explicit methods have the advantage that they can fully exploit the power of existing mathematical programming algorithms. Their disadvantage is the high information burden placed on the decision maker. Implicit i.e.
Time development of Čerenkov radation
(Monterey, California. Naval Postgraduate School, 1984-05) Neighbours, John Robert; Buskirk, Fred Ramon; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS); Physics
Most developments of Čerenkov radation are in terms of the Fourier components of the fields and power emitted by a single electron. When many electrons in a compact bunch are emitted from an accelerator, the bunch radiates coherently and at a lower frequency than for a single electron. The theory for the time structure of the fields arising from a charge bunch is developed, and it is shown that the source of the radiation is di/dt. Present detector technology should be able to resolve these fields. (Author)
Methodology for determining sampling intervals
(Monterey, California. Naval Postgraduate School, 1980-11) Larson, Harold J.; Jayachandran, Toke; Operations Research (OR); Graduate School of Operational and Information Sciences (GSOIS)
A new methodology for the determination of sampling intervals to be used with the spectrometric oil analysis program have been developed. The methodology has been tested with preliminary data and appears to perform well.
