CIVINS / Increasing awareness of environmental issues related to product design, development, use and disposal is requiring that designers account for environmental issues that had previously been neglected. In the military, these requirements are being added at the same time budgets are being cut and performance expectations are being increased. A successful design must be able to incorporate a strategy that will satisfy cost, performance, quality, maintenance and legal criteria while also opti...

CIVINS / Recent advances in computational hydrodynamics offer the opportunity to incorporate more accurate analyses earlier in the ship design process. In particular, significant work has been conducted towards the prediction of nonlinear wave-induced motions and loads in the time domain. Seakeeping analysis has traditionally been incorpo- rated late in the design process, using parametrics and two-dimensional linear strip theory methods in the frequency domain. Model testing, due to its relativ...

Includes supplemental material. / Based on public law and Presidential mandate, ballistic missile defense development is a front-burner issue for homeland defense and the defense of U.S. and coalition forces abroad. Spearheaded by the Missile Defense Agency, an integrated ballistic missile defense system was initiated to create a layered defense composed of land-, air-, sea-, and space-based assets. The Ship Anti-Ballistic Response (SABR) Project is a systems engineering approach that suggest...

Morley, Michael G.

In this thesis, acoustic inversion methods are employed to estimate array element locations and the geoacoustic properties of the seabed using measured acoustic data consisting of noise from a surface ship in the Gulf of Mexico. The array element localization utilizes relative travel-time information obtained by cross-correlating the recorded time series of ship noise received at spatially separated hydrophones. The relative travel-time data are used in an inversion, based on the regularized...

LaFontant, Patrick B.

A nonlinear maneuvering model based on ship geometric and mass properties is developed. The model can be utilized to evaluate maneuvering performance early in the design phase. This model is also used in this thesis as a benchmark in order to evaluate the accuracy of the simpler Nomoto's model. The latter is faster to simulate and is ideally suited for visual simulation studies. Results comparing the relative accuracy and speed of implementation of the two models are presented for different inpu...

Approved for public release; distribution unlimited. / Surface wave action has been proven to be the biggest deterrent to a ship's progress through the water. Until the present time forecasts of surface waves have been available for only a few days. In order to determine an optimum ship route across the ocean these wave forecasts must be extended to 15-20 days. Using three computer programs from the Fleet Numerical Weather Facility and the U.S. Weather Bureau 5-day and 30-day forecasts of ...

A mathematical model describing the fundamental physics of a ship/ ramp/barge system, including a passive isolator, is developed. The model properly accounts for hydrodynamic proximity effects and structural coupling between the bodies. A standard second order model is used, for demonstration purposes, in order to model the frequency response properties of the connecting body. Parametric studies of the response amplitude operator of the ramp motion are performed for varying wave directions and i...

Approved for public release; distribution is unlimited / The scheduling of events aboard U.S. Navy ships is a complex and dynamic problem. Currently, this process is primarily manual and involves searching through several manuals and instructions to find information. Many times the schedules produced are inaccurate, which can make conducting activities very difficult and result in crew frustration. By automating some of the functions of the scheduling process, accurate schedules can be qu...

In this work we review the problem of radar imaging satellites' dependency on ground stations to transfer the image data. Since synthetic aperture radar images are very big, only ground stations are equipped to transfer that much data. This is a problem for maritime surveillance as it creates delay between the imaging and processing. We propose a new hardware algorithm that can be used by a satellite to detect ships and extract information about them, and since this information is smaller it can...

Approved for public release; distribution is unlimited / The United States Navy has solicited proposals for a revolutionary class of ship, the Arsenal Ship. Despite reduced funding for the project, the concept is still viable for future development. We show how the development of a new unparalleled weapon system or platform will evoke a response by potential adversaries, based on capabilities and asset investment, by unconventional means. The Arsenal Ship is a formidable threat, yet is vulnerabl...

In order to improve ship self-defense against sea-skimming missiles, several concepts, such as the free electron laser, high-power microwaves, and the Phalanx gun system are reviewed and evaluated in this thesis. Phalanx computer simulations show that Phalanx is an inadequate means of protection. High-power microwaves are found to damage electronics, but calculations show limitations due to diffraction and the possibility of shielding. This thesis evaluates several damage mechanisms caused by th...

High-power Free Electron Lasers (FELs), capable of stopping an incoming anti-ship missile, can be an effective addition to the self-defense system of a modem naval combatant. A shipboard FEL must be compact, efficient, and capable of reliable operation in a naval environment. This thesis explores the feasibility of integrating a 1MW infrared FEL aboard a surface combatant from a Total Ships Systems perspective. A study of system aspects including vibrational effects and ship/weapon interfaces wi...

This thesis improves the method of determining inventory levels for commodities (provisions, high usage load list consumables, and ships store merchandise) managed by the Sixth Fleet on station AFS. Historical demand generated by ships deployed to the Sixth Fleet is used to develop two models, the Lognormal Model and the Point Estimate Model. Improvement is achieved by considering each item's variance in demand. The Lognormal Model computes sample standard deviations for each item and provides t...

CIVINS / An internal airblast from a missile explosion produces tearing, holing and dishing of ship's structural plating. In order to analyze the residual strength of a ship after an internal explosion, a typical ship compartment was considered to be composed of flat square plates subjected to uniaxial compression, and the damage effects were examined independently. The holing was considered to be a centrally located circle. Plastic limit load analysis of a flat plate indicates that ultimate str...

Natural Killer (NK) cells comprise a unique subset of lymphocytes with innate ability to detect and kill abnormal cells. Inhibitory Ly49 receptors expressed on NK cells recognize major histocompatibility complex class I (MHC I) molecules and inhibit NK cell killing of normal cells that express high amounts of MHC I. In addition to maintaining self-tolerance of NK cells, the Ly49:MHC I interaction is required for the functional maturation of NK cells by a process termed “NK cell licensing.” NK ce...

SHIP (SH2-containing inositol 5'-phosphatase) is a hematopoietic restricted enzyme responsible for the hydrolysis of the phosphatidylinositol 3-kinase-generated second messenger PI-3,4,5-P₃ to PI-3,4-P₂ and, thereby, negatively regulates cell survival, proliferation and differentiation. Herein, we demonstrate a role for SHIP in the differentiation and function of dendritic cells (DCs). We found that SHIP restrains in vitro generation and survival of bone marrow derived DCs cultured with granulo...

The currents in the Burlington Ship Canal were found to be the result of a variety of driving mechanisms. Wind driven upwelling at the western end of Lake Ontario creates a horizontal density gradient through the canal driving baroclinic currents. Wind initiated standing waves and lunar tides in Lake Ontario cause water surface gradients through the canal driving barotropic currents. The barotropic currents are also strongly affected by Helmholtz or Harbour Resonance. A water balance showe...
