Most of the works published on hydrodynamic parameter identification of open-frame underwater vehicles focus their attention almost exclusively on good coherence between simulated and measured responses, giving less importance to the determination of “actual values” for hydrodynamic parameters. To gain insight into hydrodynamic parameter experimental identification of open-frame underwater vehicles, an experimental identification procedure is proposed here to determine parameters of uncoupled and coupled models. The identification procedure includes: (i) a prior estimation of actual values of the forces/torques applied to the vehicle, (ii) identification of drag parameters from constant velocity tests and (iii) identification of inertia and coupling parameters from oscillatory tests; at this stage, the estimated values of drag parameter obtained in item (ii) are used. The procedure proposed here was used to identify the hydrodynamic parameters of LAURS—an unmanned underwater vehicle developed at the University of São Paulo. The thruster–thruster and thruster–hull interactions and the advance velocity of the vehicle are shown to have a strong impact on the efficiency of thrusters appended to open-frame underwater vehicles...

Esta dissertação analisa o processo de aprendizagem e transformação organizacional da seção naval do Instituto de Pesquisas Tecnológicas (IPT), a partir do final dos anos 1990, com base em pesquisa documental e entrevistas com atores-chave. Como pressuposto, assume-se que Instituições Públicas de Pesquisa (IPPs) são entidades que criam conhecimentos e competências e, com isso, aprendem e evoluem organizacionalmente por meio de um processo ativo de relacionamento com o ambiente científico, tecnológico, econômico e social. As competências adquiridas são indicadores do processo de aprendizagem e evolução organizacional. Para isso busca-se reconstruir a trajetória da seção naval do IPT e sua relação com o contexto político e econômico, a fim de identificar as circunstâncias que motivaram suas transformações organizacionais, as oportunidades de aprendizagem e a aquisição e/ou perda de suas competências. A pesquisa mostra como o contexto dos anos 1990, das crises políticas e fiscais, do desmonte parcial do setor naval e da transformação dos atores desse setor, ameaçou desarticular as competências de pesquisa da seção naval do IPT. Já o momento da "retomada do setor naval", a partir do final dos anos 1990...

The United States Navy is under pressure to reduce the cost of fleet maintenance in order to redirect funds for the construction of new ships and submarines. The Navy looks to private industry for process improvement ideas such as the Theory of Constraints, Six Sigma and Lean Manufacturing Principles. This thesis examines the Lean Manufacturing movement in the private sector of ship repair and how it eventually came to government owned ship repair operations. Recent National Ship Research Program (NSRP) initiatives provide shipyards a strategy of how to select areas of an operation for Lean improvements. The Norfolk Naval Shipyard method is a combination of the Theory of Constraints, Six Sigma and Lean Principles called Lean Sigma. The Lean Sigma methodology for planning, executing and sustaining lean improvement and how to measure success with various metrics is presented. Lean Sigma is implemented into the Electric Motor Rewind and Repair Center as a case study. Before and after assessments, lessons learned, and recommendations from the implementation case study are presented.; (cont.) Details of the challenges and pitfalls encountered during the Lean Sigma implementation in the areas of culture, budget, management, metrics and cost benefit measurement...

The basis for this thesis involved a six and a half month LFM internship at the Amazon.com fulfillment center in the United Kingdom. The fulfillment center management sought insight into the substantial variation across the entire fulfillment center. This variation manifested itself primarily in two areas: the individual process path productivities of picking, pre-sort, re-bin and packing, and the overall system productivities of fulfillment center cycle time and throughput. Employee productivities, within picking, pre-sort, re-bin and packing, varied substantially, with this variation having a significant effect on throughput. This thesis uses discrete event simulation and the program SIMUL8 to model the overall system and analyze the effect of this variation. It discusses the design and development process for the model, proposes key questions relative to variation, analyzes different scenarios, and recommends specific actions for implementation. The overall goals of the internship included increasing fulfillment center throughput and decreasing cycle time.; by Cameron S.

Air-water interaction flow between two parallel flat plates, known as Couette flow, is simulated by direct numerical simulation. The two flowing fluids are coupled through continuity of velocity and shear stress condition across the interface. Pseudo-spectral method is used in each flow subdomain with Fourier expansion in streamwise and spanwise directions and finite difference in vertical direction. Statistically quasi-steady flow properties, such as mean velocity profiles, turbulent intensities, Reynolds stress and turbulent kinetic energy (TKE) budget terms show significant differences between air-water interface turbulence near the water side (IntT-w) and wall-bounded turbulence(WT) while there are some similarities between IntT-w and free surface turbulence (FST). Due to the velocity fluctuation at the interface, water side near interface turbulence flow (IntT-w) is characterized with a thinner viscous sub-layer and decreased intercept parameter B in log-law layer, strengthened Reynolds stress and eddy viscosity, together with a stronger production term, decreasing-then-increasing dissipation term and negative turbulent diffusion term in TKE budget.; (cont.) Abundant physical phenomena exist on the water side turbulent flow with four major types of three-dimensional vortex structures identified near the interface by variable-interval spacing averaging (VISA) techniques. Each type of vortex structures is found to play an essential role in the turbulent energy balance and passive scalar transport.; by Song Liu.; Thesis (S.M. in Mechanical Engineering and S.M. in Ocean Engineering)--Massachusetts Institute of Technology...

Approved for public release; distribution is unlimited; Future underwater missions will require data transmission via satellite. In particular, the Office of Naval Research (ONR) is interested in experimenting with communications using the GOES satellite system, which is government owned. Unfortunately, communication antennas must point to specific satellites in this system and thus underwater vehicles must steer a specific course on the surface during the communication process. While surfaced, underwater vehicles are subject to wind and wave disturbances and it has been suggested that control using differential thrust from propellers may provide advantages. This thesis covers efforts to create and test such a steering autopilot based on the use of the ARIES AUV and differing the voltage supplied to each propeller. It is planned to use the ARIES in an ocean experiment to test this satellite communication capability. This control is embedded in the control of ARIES during extended pop up maneuvers for GPS navigational fixes. When surfaced, not only are navigational fixes obtained, but also data packets are communicated to a command center.

The sensitivity of numerical solutions of systems of nonlinear flow equations (Navier-Stokes equations) to the grid used is investigated through the use of the South China Sea (SCS) numerical ocean model. Traditionally, rectangular coordinate grids are used in environmental modeling. The advantage of rectangular coordinate grids is their simplicity in the generation process. However, rectangular coordinate grids are not well suited for regions with complex terrain (coastlines and topography) and occasionally lead to poor accuracy in numerical solutions. The grid generation techniques are being introduced to coastal ocean modeling to study the sensitivity of numerical solutions to the grid used and to investigate the enhancement of the modeling process. Grid generation techniques are broadly used in aeronautical engineering community for solving CFD problems. One orthogonal (l2lxl9l) and two curvilinear nearly-orthogonal grids (l2lxl9l and lSlx24l) are designed to couple with the SCS numerical ocean model. The grids are designed using the EAGLEView grid generation code developed by the National Science Foundation (NSF) Engineering Research Center (ERC) of Mississippi State University. EAGLEView implements a grid generation technique using mainly elliptic and algebraic generation systems. The designed grids are processed with the SOS numerical ocean model for 200 days to study the sensitivity of numerical solutions to the grid used. The solutions of the temperature and salinity fields are presented and analyzed. The advantages of curvilinear nearly- orthogonal grids are also discussed. (MM)

A large part of operating costs of a hotel in Hawaii is the cost of energy for air conditioning. Buildings can be constructed to use energy more efficiently by using many methods, however, some of these methods conflict with other concerns, aesthetics for example. Thus the process of designing and building an energy efficient hotel often involves trade-offs between energy efficiency and other objectives...

This thesis examines radio propagation conditions over trans- equatorial (TE) paths. The study precedes Project PENEX, a field experiment to measure and collect calibrated HF skywave signal strength data for polar, equatorial. and near-vertical incidence propagation paths. PENEX will benchmark the absolute accuracy of the signal-to-noise models in the MEDUSA propagation model now being developed by the Naval Command, Control and Ocean Surveillance Center. Since only minimal information is available about TE paths, a comprehensive review of the published literature on TE experiments was completed, with emphasis oil TE paths between magnetic conjugate points. Data from such paths have revealed the presence of unusual propagation i-nodes which are not predicted by standard propagation programs such as PROPHET, IONCAP, and AMBCOM. The review of the literature revealed that Stanford Research Institute (SRI) published measured data on a TE path between the Pacific islands of Kauai and Rarotonga. A comparison was made between the SRI data and predictions for the same path to assess the usefulness of current prediction programs for TE paths. The SRI AMBCOM program was used for this comparison. As expected, sizeable differences were found between the predicted and measured results...

Approved for public release, distribution is unlimited; MLAYER, a computer program, was developed by the Naval Ocean Systems Center (NOSC) for calculating the signal levels of electromagnetic waves propagating in a multilayer tropospheric waveguide environment over seawater. The program is an extension of the XWVG which is a trilinear ducting program. Modifications of the XWVG were carried out to handle multilayer tropospheric ducts. A number of modifications and improvements on the program made over the past several years were not documented. A detailed documentation of MLAYER was also not available. The object of this thesis is to develop a technical documentation for MLAYER using the program as baseline. The study aims to put together the theoretical formulations (specific to MLAYER) into a complete self- contained document. This is to facilitate potential users with better appreciation of the capabilities, limitations, approximations and assumptions used in the mathematical modelling techniques. As far as possible, the same terminologies and functional variables used by Baumgartner (in the XWVG development) and by Pappert (in the MLAYER development) are adopted to enable one to relate this document to the program. Step-by-step derivation of certain equations was carried out and checked for compatibility with the algorithm in the program.

Approved for public release; distribution is unlimited; The Naval Command, Control and Ocean Surveillance Center (NCCOSC), Research Development Test and Evaluation (RDT & E) Division's (NRaD) communications Department is conducting applied research toward the development of a high-data-rate (HDR), line-of-sight (LOS), digital modem for ship-to-ship, ship-to-shore, and ship-to-relay communications. Development of bandwidth efficient HDR communications in a maritime radio environment is a challenging research problem due to the time-varying propagation effects within the marine layer. Marine layer propagation typically causes fading of the signal spectrum due to RF interference effects, and intersymbol interference because of multipath induced time spreading. The use of adaptive equalization to overcome distortions is difficult in this environment because of the dynamic nature of the signal propagation caused by transmitter and/or receiver motion and the maritime layer atmospheric effects. An alternative to channel equalization is the application of Coded Orthogonal Frequency Division Multiplexing (COFDM) which overcomes distortion effects without equalization through its orthogonality properties. This thesis explores the application of COFDM toward a HDR LOS maritime communications modem. The modem model is emulated in MAThAB and simulations are performed. Analysis of the simulations are conducted and evaluated Qs to the feasibility of a COFDM implementation in the presence of known noise and signal fading conditions; http://archive.org/details/codedorthogonalf00rode

With the reduction of funding for sea ice reconnaissance flights, the National/Naval Ice Center needs to capitalize on the improvements in satellite technology. Imaging sensors such as AVHRR, DMSP/OLS, SSM/I and RADARSAT have been used to detect the presence of sea ice, but with the exception of SSM/I and RADARSAT, clouds are a major obstacle to viewing the surface. With NASA's development of the Moderate-resolution Imaging Spectroradiometer (MODIS) and MODIS Airborne Simulator (MAS), there is finally a sensor capable of using multi-spectral techniques to detect the presence of clouds. A group at the Space Science and Engineering Center (S SEC), University of Wisconsin - Madison lead by Dr. Steve Ackerman has developed a mask for MAS/MODIS. The technique determines a level of confidence that a given pixel is clear based on a series of multi-spectral tests. By combining the confidence level from all tests, it is possible to detect the presence of clouds at different altitudes in the atmosphere. Based on the Ackerman et al. (1997) scheme, threshold optimizations were made on the T(beta)(ll micrometers) and T(beta)(3.9 micrometers) - T(beta) (ll micrometers) tests, while the T(beta)(ll micrometers) - T(beta)(l2 micrometers) test was removed. These are daytime modifications based on analysis of several MAS and a limited number of MODIS cases. From subjective analysis...

Approved for public release; distribution is unlimited.; This thesis examines the Cost and Performance Measurements within four Program Directorates at the Space and Naval Warfare Systems Command (SPAWAR). SPAWAR is the Navy's full-spectrum research, development, test and evaluation, engineering and fleet support center for Command, Control and Communications Systems, Ocean Surveillance Systems and the integration of those systems that overarch multiplatforms. In the era of lean military budgets, public and congressional demands for improved performance within government and performance based budgeting, Commands must justify their budgets and resource allocation relating to costs and outputs. How can commands determine the efficiency of their organizations without accurate cost and output measurement? The primary focus of this thesis is to describe the cost and performance measurement systems applied in the SPAWAR Program Directorates to determine what types of cost, scheduling and performance information they provide for the command. This was accomplished by conducting personal interviews of SPAWAR personnel and reviewing official SPAWAR records. The components of the Program Directorates, the Program Manager Warfare use a wide variety of locally designed computer programs and tracking systems to measure cost...

CIVINS; The Navy has traditionally used treated timber materials for fender systems for piers and wharves in Pearl Harbor. In recent years, the costs associated with the use of timber have escalated and the Navy has begun to use plastic piles at installations around the world to replace timber fender systems. Plastic fender systems are more expensive, but have greater energy absorption capabilities and are more resilient to environmental decay. To determine whether plastic piles are a cost saving alternative to treated timber, the present study compiled and evaluated existing technical data, maintenance/ construction records and inspection reports from various Navy staff civil engineer offices and at the Navy Public Works Center Pearl Harbor (PWC). Since records at these various locations were not designed to present associated cost/ maintenance data in a format suitable for an economic analysis, field surveys of over 3 miles of waterfront in Pearl Harbor and interviews with staff civil engineers and wharf building branch managers at PWC were conducted to supplement existing historical data. Through the gathered data, the maintenance costs of timber pile fenders are estimated and compared to those of composite plastic piles using manufacturers' quotes and from reports compiled by the Navy Civil Engineering Laboratory (NCEL). For the expected life cycles of timber piles observed in Pearl Harbor this analysis shows the proposed plastic system to be more cost effective for shore facilities with remaining service lives of greater than ten years; http://www.archive.org/details/timbervscomposit00alli; CIVINS

A number of autonomous underwater vehicles, AUV, are equipped with commercial ducted propellers, most of them produced originally for the remote operated vehicle, ROV, industry. However, AUVs and ROVs are supposed to work quite differently since the ROV operates in almost the bollard pull condition, while the AUV works at larger cruising speeds. Moreover, they can have an influence in the maneuverability of AUV due to the lift the duct generates in the most distant place of the vehicle's center of mass. In this work, it is proposed the modeling of the hydrodynamic forces and moment on a duct propeller according to a numerical (CFD) simulation, and analytical and semi-empirical, ASE, approaches. Predicted values are compared to experimental results produced in a towing tank. Results confirm the advantages of the symbiosis between CFD and ASE methods for modeling the influence of the propeller duct in the AUV maneuverability. (C) 2012 Elsevier Ltd. All rights reserved.

The spatial and temporal variability of ocean wind waves plays an important role in many engineering and environmental problems. Although research in this area has been improved in recent decades thanks to the emergence of satellite data, in many cases this information does not have the appropriate resolution for more detailed and local research. In view of this, reanalysis data developed by several meteorological agencies have appeared as a good alternative to force the most popular ocean wind-wave models. Thus, to achieve more accuracy in the data, the 60-yr Global Atmospheric Reanalysis 1 carried out by the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) has been corrected, employing the vector correlation and triple collocation theories combined with information from different accurate sources. The comparison of wind speed with satellite and in situ buoy data before correction reveals an important underestimation for areas near the Colombian coast. The wind speed root-mean-square error (RMSE) between corrected data and satellite measurements at locations near the Colombian Caribbean coast without calibration is 3.8ms-1 while for corrected data it is 2.0ms-1, showing a decrease in the RMSE of almost 47%.

The thesis explores the use of the Non-intrusive Load Monitor (NILM) in Condition Based Maintenance (CBM) applications on US Navy ships as part of the Office of Naval Research Electric Ship Integration (ESI) Initiative. The NILM is a device that measures an electrical component's performance by applying a single voltage and current transducer to a ship's existing power distribution system. The NILM was originally developed to monitor electrical power usage in buildings where it was noticed that it could disaggregate and report the operation of individual loads when many loads were present. The limits of this capability are explored by employing a signal processing script in MATLAB using component data gathered on the USCGC SENECA (WMEC-906). The plausibility of using a few NILMs to provide machinery monitoring information for an entire engineering space, and the resulting opportunity to reduce sensor growth on future Navy ships is explored. Then efforts to monitor naval propulsion plant machinery with the NILM are discussed. Two NILMs were constructed and installed on selected individual components at the Naval Surface Warfare Center Philadelphia DDG-51 Land Based Engineering Site (LBES).; (cont.) Monitoring of the Fuel Oil and Low Pressure Air Service Systems was conducted during a week long certification of the pre-commissioning crew of the USS BAINBRIDGE (DDG-96). Data collected was then used to explore the use of the NILM as a diagnostic device for shipboard systems through the evaluation of mechanical transients in the Fuel Oil system and a test leak inserted into the Low Pressure Air System.
