This thesis document was issued under the authority of another institution, not NPS. At the time it was written, a copy was added to the NPS Library collection for reasons not now known. It has been included in the digital archive for its historical value to NPS. Not believed to be a CIVINS (Civilian Institutions) title.; The need for a means of making ocean current observations that will be both rapid and economical is becoming critical. Contrary to what one might assume, there are many areas of the ocean today that have been inadequately surveyed with respect to currents. Of the approximately 550 Marsden Squares which compromise the world ocean one finds that the mean monthly distribution of current observations amounts to only 3.8 observations per Marsden Square (Engler 1963). When one considers the size of a Marsden Square it is not difficult to visualize how unsatisfactory the state of knowledge of current systems is. To claim a complete understanding based on a mean monthly distribution of only 3/8 observations for every 360,000 square nautical miles is almost sheer folly. It would seem that there is hardly sufficient data to locate currents let alone to gain an understanding of any degree of variability of meandering. The demand for environmental information...

A centrifuge system was designed and constructed to investigate nucleate pool boiling of water from a mirror finished copper surface. The system was constructed to withstand acceleration force levels up to 1800 g's and to operate at heat fluxes to 200,000 BTU/hr-ft2. No nucleate boiling data was taken due to minor experimental difficulties and due to more serious problems that developed with the heater wire and especially with the thermocouple instrumentation. The system was operated to 460 RPM (200 g's) during calibration runs however, and was observed to function well.; http://www.archive.org/details/nucleatepoolboil00hart; Lieutenant, United States Navy

Approved for public release; distribution is unlimited; Pool boiling heat transfer of nitrogen from artifical cavities was investigated. Boiling was from circular, one inch diameter horizontal mirror finished copper plates. The single artifical cavity surfaces investigate were: a drilled 0.0043 inch diameter hole, a drilled 0.015 inch diameter hole, and 0.022 nich diameter spark cut cone, and an 0.006 inch diameter spark cut cylindrical hole. The multiple cavity surfaces investigated were: seven 0.015 inch diameter drilled holes, thirteen 0.015 diameter drilled holes, and ninety-seven 0.003 to 0.0045 inch diameter spark cut holes. The depth to diameter ration was about 2.5 for all drilled cavities. The data from a mirror finished surface was compared to that of previous investigations. Exponents for Yamagata's Equation for boiling in the isolated bubble region were determined. The artificial cavities were found to affect the natural convection heat transfer. The size of the cavity appeared to have little effect after incipience of boiling, and larget cavities than previously expected were found to remain active; http://www.archive.org/details/nucleatepoolboil00moul; Lieutenant, United States Navy

Numerical study of secondary effects in flexibility analysis of an ell-shaped piping structure

Português
Approved for public release; distribution is unlimited; This thesis considers the influence of four secondary effects on the analysis of a simple elle-shaped piping structure when it is uniformly heated. The four effects are: (a) axial deformation, (b) shearing deformation, (c) beam-column effect, and (d) difference between arc and chord. They are usually neglected in a piping flexibility analysis. In a paper of several years ago, J. E. Brock developed a theory for this investigation but did not present any numerical results or conclusions. The present thesis reviews Brock's theory and corrects some errors in coefficients. It then describes a digital computer program for IBM System 360 which performs the corresponding caluclations. Finally, it draws the new and quite significant conclusion that conventional piping stress analysis, which neglects these secondary effects, can result in gross errors in evaluating stresses in piping configurations which are likely to be encountered in piping practice; http://www.archive.org/details/numericalstudyof00mile; Lieutenant, United States Navy

Português
With the advent of the high speed digital computer, many problems heretofore considered unsolvable for all practical purposes are now well within the reach of the applied mathematician. One such problem is the routing of a shin through a time dependent ocean wave field, from one point on the earth's surface to another, so as to minimize a cost function of the form g(x,y,t,u). This paper considers a numerical solution to the above problem. The technique to be employed is known as the method of steepest ascent and is attributed to Arthur E. Bryson and Walter F. Denham [1]. Although the computer program as given in the Appendix is written specifically for a VC2AP3 class vessel operating in a described area of the North Pacific Ocean, it can be readily modified to accommodate any type vessel operating in the Northern Hemisphere.; http://www.archive.org/details/optimumshiprouti00greg; Lieutenant, United States Navy

Português
We present new methods for modeling nonlinear threshold-type autoregressive behaviour in periodically correlated time series. The methods are illustrated using a series of average monthly flows of the Fraser River in British Columbia. Commonly used nonlinearity tests of the river flow data in each month indicate nonlinear behaviour in certain months. The periodic nonlinear correlation structure is modelled nonparametrically using TSMARS, a time series version of Friedman's extended multivariate adaptive regression splines (MARS) algorithm, which allows for categorical predictor variables. We discuss two methods of using the computational algorithm in TSMARS for modeling and fitting periodically correlated data. The first method applies to the algorithm to data from each period separately. The second method models data from all periods simultaneously by incorporating an additional predictor variable to distinguish different behaviour in different periods, and allows for coalescing of data from periods with similar behaviour. The models obtained using TSMARS provde better short-term forecasts for the Fraser River data than a corresponding linear periodical AR model.

For those who say that comparing the current war in Afghanistan to the Vietnam War is taking things too far, here’s a reality check: It’s not taking things far enough. From the origins of these North-South conflicts to the role of insurgents and the pointlessness of this week’s Afghan presidential elections, it’s impossible to ignore the similarities between these wars. The places and faces may have changed but the enemy is old and familiar. The sooner the United States recognizes this, the sooner it can stop making the same mistakes in Afghanistan.

Approved for public release; distribution is unlimited; The objective of the Penn State University (PSU) part of the study was to investigate the MM5's ability to simulate wintertime fog in the San Joaquin Valley (SJV) and summertime sea breeze flows in the South Coast Air Basin (SoCAB). For the SJV work the MM5 was configured with four nested grid and an advanced turbulence sub-model. Applied to the event of 7-12 December 1995, observed during the IMS-95 program, the model's innermost domain used 40 vertical layers and a 4-km mesh. Several experiments were performed to improve the turbulence sub-model for saturated conditions and to provide more accurate initial conditions for soil temperature and moisture. Results showed the MM5 correctly predicted the type of visibility obscuration (fog, haze, status or clear) in 14 out of the 18 events. For depth was estimated by the MM5 with a mean absolute error of only 92 m and a mean error of -41 m. Mean errors for both the surface temperature and dew point were within +1C, while the mean absolute errors were ~1.5-2.0 C. As a consequence, the mean error for dew-point depression is very small. Thus, the MM5 was shown to simulate fog and haze in the SJV with considerable accuracy. Extensions of the turbulence sub-model to include saturation effects and the specification of accurate soil temperature and moisture were important for simulating fog characteristics in the case.

Anomalously high reflectivity tracks in stratus and stratocumulus sheets associated with ships (known as ship tracks) are commonly seen in visible and near-infrared satellite imagery. Until now there have been only a limited number of in situ measurements made in ship tracks. The Monterey Area Ship Track (MAST) experiment, which was conducted off the coast of California in June 1994, provided a substantial dataset on ship emissions and their effects on boundary layer clouds. Several platforms, including the University of Washington C-131A aircraft, the Meteorological Research Flight C-130 aircraft, the National Aeronautics and Space Administration ER-2 aircraft, the Naval Research Laboratory airship, the Research Vessel Glorita, and dedicated U.S. Navy ships, participated in MAST in order to study processes governing the formation and maintenance of ship tracks. This paper tests the hypotheses that the cloud microphysical changes that produce ship tracks are due to (a) particulate emission from the ship’s stack and/or (b) sea-salt particles from the ship’s wake. It was found that ships powered by diesel propulsion units that emitted high concentrations of aerosols in the accumulation mode produced ship tracks. Ships that produced few particles (such as nuclear ships)...

Free Surface Effects on the Near-Inertial Ocean Current Response to a Hurricane

During the passage of hurricane Frederic in 1979, four ocean current meter arrays in water depths of 100- 950 m detected both a barociinic and a depth-independent response in the near-inertial frequency band. Although the oceanic response was predominately barociinic, the hurricane excited a depth-independent component of 5-11 cm S-I. The origin and role of the depth-independent component of velocity is investigated using a linear analytical model and numerical simulations from a 17-level primitive equation model with a free surface. Both models are forced with an idealized wind stress pattern based on the observed storm parameters in hurricane Frederic. In an analytical model, the Green's function (Ko) is convolved with the wind stress curl to predict a sea surface depression of approximately 20 cm from the equilibrium position. The near-inertial velocities are simulated by convolving the slope of the sea surface depression with a second Green's function. The barotropic current velocities rotate inertially with periods shifted above the local inertial period by I %-2% and the maximum amplitude of II cm S-I is displaced to the right of the track at x = 2Rmax (radius of maximum winds). The free surface depression simulated by the primitive-equation model is also about 18-20 cm. The primitive equation model simulations indicate that the vertical mean pressure gradient excites 10-11 cm S-I depthaveraged currents atx = 3Rmax . The net divergence and convergence of the horizontal velocities induces vertical deflections of the sea surface. The spatial pattern of the barotropic amplitudes simulated by the numerical and analytical models differ by less than 2 cm S-I in the region 0 < x < 4Rmax> which suggests that the barotropic response to the passage of a moving hurricane is governed by linear processes.

Approved for public release; distribution unlimited; This thesis concludes that Soviet expenditures in Indochina, particularly Vietnam, have significantly reduced assets and options available to the USSR in Europe. Economic, military, and political expenditures are assessed. Tradeoffs between the Soviet Union's Indochina resource commitments and European limitations are established. Based on these tradeoffs, three policy options for the United States in South-East Asia are formulated -- hardline, low key, and minimal involvement. A 'low key' option, with emphasis on diplomatic and economic instruments, is recommended as preferrable to military means.

Approved for public release; distribution unlimited; This thesis studies the system used by the Coast Guard to capitalize property. Capitalization impacts upon both the physical accountability for property and the accuracy of financial records. The system for property capitalization and control is analyzed first by reviewing the accounting principles applicable to all Federal agencies. Implementation of the property accounting system is then evaluated through field research at the USCG Group Office, Monterey, California After consideration of issues relevant to capitalization problems in current practice, improvements to the system are recommended. This thesis concludes that, with proper implementation, the system will provide the required control. Recommendations are concerned with correcting the system's implementation problems.; http://archive.org/details/analysisofcapita00conl; Lieutenant, United States Coast Guard

Approved for public release; distribution is unlimited.; This study is an analysis of the local delivery system at the Naval Supply Center Oakland, California. Specifically, the study provides information regarding the average costs of deliveries to various customer locations and how driver time is distributed between travel and non-travel functions. As a result of the study, the authors concluded that Naval Supply Center Oakland and Public Works Center San Francisco are more concerned with the effectiveness of the local delivery operation than with its efficiency. Accordingly, recommendations regarding modifications to the current local delivery operation are provided in an effort to more evenly balance the emphasis between the system's effectiveness and efficiency; http://archive.org/details/analysisoflocald00alli; Lieutenant Commander, Supply Corps, United States Navy; Lieutenant Commander, Supply Corps, United States Navy
