Regulations governing the discharge of sewage from ships have been in force since the early 1970's. In response, the marine industry has developed ever more complex systems and processes for managing these wastes. The first compliance method involved holding wastes until they could be legally discharged;as technology advanced, treatment systems were developed and installed to enable discharge within regulated waters. As the size and number of ships as increased with maturation of the ocean tourism business, more restrictive regulations have been enacted to minimize the impact on sensitive waters. The trend is toward increasing regulation of both sewage and graywater. The most recent action occurred on 12 October 2005 when the Governor of California signed into law Senate Bill 771 regulating most ship liquid discharges within state waters. This paper describes the development of an innovative advanced wastewater treatment technology, based on advanced oxidation, bearing in mind the lessons learned from systems developed by industry over the past thirty years.

The purpose of this study is to construct an interactive system which composes a musical work satisfying each user. This study makes a great importance to human subjectivity toward music, and constructs a music composition system reflecting each user's feeling. The system uses 3 types of user evaluations toward music to generate 16-bars musical work. The interactive genetic algorithm is applied to the present system, and user evaluations are employed instead of GA's objective fitness functions. In this paper, chromosomes, which have information on 4-bars musical work, are generated in the pool, and the GA operations based on user evaluations are executed to them. From the results of the evaluation experiments, it is found that our system composes music reflecting user's feeling.

A novel PNN (Probabilistic Neural Networks) hardware architecture called 'Sigma Parallel Architecture' (SPA) is proposed. Different values of the network parameter are calculated in parallel in the SPA and it speeds up the PNN learning as well as recognition overcoming the difficulty in the VLSI implementation. The hardware prototype is developed using FPGA chips and it shows a high speed leaning of about 10 seconds that satisfies the requirements in the real world image recognition tasks.

Total ship training for future aircraft carriers

引用

NAVAL ENGINEERS JOURNAL 2000年第3期112卷 111-123页

作者： Whitten, T Rikansrud, E Mr. Tim Whitten:is the Training Manager for the NAVSEA CVNX Future Aircraft Carriers Program. Prior to coming to NAVSEA Mr. Whitten worked at the Naval Air Warfare Center Training Systems Division (NAWCTSD) as the Front End Analysis Lead for the San Antonio Class Amphibious Transport Docking Ship (LPD 17). He holds a master's degree in counseling psychology from Nova University Fort Lauderdale Florida. He received his bachelor's degree in psychology from the University of Central Florida Orlando Florida. Mr. Edward Rikansrud:is the CVNX Project Engineer for Training Systems at NAWCTSD. Mr. Rikansrud has held project engineering positions for a wide variety of surface subsurface and air training system development programs. In addition to CVNX Mr. Rikansrud has most recently been involved with the development of shipboard total ship training systems for the LPD 17 and DD 21 (Surface Combatant for the Twenty first Century) platforms. He holds a bachelor of science degree in electrical engineering (BSEE)from the University of Florida Gainesville Florida.

The use of technology to assist in the missions of the Navy has changed. The twenty-first century will see a Navy with fewer but more technical ships, smaller yet more innovative shipboard crews, and the need for rapid responses to changing world battle and peacetime scenarios. A recent study (Defense Science Board 1997) has noted the Navy is compelled to build ships that will operate with smaller crews at the same time operational environments require increased capabilities. The Defense Science Board study (1997) further states that, "Training is a force multiplier that allows manning reductions through better use of personnel onboard." The purpose of this paper is to describe a total ship training philosophy for the CVNX class of future aircraft carriers. The Navy has developed an affordable plan to evolve the baseline design of CVNX over multiple hulls for the new construction of aircraft carriers (NAVSEA 1999). Each of these platforms will employ successively more advanced training methods and systems, culminating in a final design that incorporates the most capable ship board total ship training program ever fielded aboard an aircraft carrier.

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 111-124页

作者： Brougham, WJ Lt. William J. Brougham:is an Engineering Duty officer (ED) in the Navy undergoing advanced studies at the Massachusetts Institute of technology. He has had tours as a submarine line officer as well as a Program Manager's Assistant for Weapons System Safety Test and Evaluation at NAVSEA PMS-350 before transferring into the ED community. Current studies include dual masters degrees in naval construction and engineering and mechnical engineering from MIT as well as a master of science management of technology (MOT) from the Sloan School of Management MIT. He has an MBA finance and investments from The George Washington University (1996) and a BS general engineering/control systems from the University of Illinios-Urbana (1988). He is a member of both the American Society of Naval Engineers and the Society of Naval Architects and Marine Engineers.

The Coast Guard wants to replace their aging cutter fleet. The new construction Deepwater Project would like to integrate their efforts with the DD 21 family of ships but the Coast Guard does not want to wait for the Navy program to mature. This study investigates the engineering feasibility of an alternate near term solution-conversion of the decommissioning Oliver Hazard Perry class frigates into Future Coast Guard Cutters (FCGC). Detailed analyses for combat system selection, propulsion plant and endurance range Limitations, and manning and automation issues form the foundation for new ship arrangements capable of supporting a mixed gender crew. Additional analysis reviews small boat operations, habitability requirements, ship stability structural loading, and a cost estimation technique. The converted Oliver Hazard Perry class frigates were shown to provide a technically feasible interim solution to replace decommissioning Coast Guard cutters while meeting or exceeding the Coast Guard requirements for a conservatively estimated cost of $141M (FY98).

He was selected for this position following several years as the deputy program managerltechnical director of the Standard Missile and Vertical Launching System programs.

A revolutionary approach to air defense has recently been extensively evaluated within the United States Navy. The approach is a new cooperative engagement capability (CEC) that allows systems to share unfiltered sensor measurement data with very small time delay and with retention of precision, enabling the units of a battle group to operate as one. The CEC system and the program for fleet introduction will be described. Further, the results of recent testing as well as new concepts toward multiwarfare, joint-services operations are discussed.

While most of the theater ballistic missiles (TBM) in threat countries' inventories are of the shorter range SCUD varieties, mid- to long-range versions are currently in development in a number of third world countries. Threat potential exists in the following three battle spaces: endo-atmosphere (0-30 km), high endo-atmosphere (30-70 km) and exo-atmosphere (greater than 70 km). The inherent short range and low speed of endo-atmospheric threats match well with capabilities of SM-2 Block IVA, which equips the Navy with an area defense capability The exo-atmospheric TBMs are longer range and can threaten more targets which may be widely dispersed. Their higher velocities reduce response times dramatically Therefore, exo-atmospheric TBMs create the need for Standard Missile-3 (SM-3), which provides the Navy with theater wide defense capability. Defining its area and theater wide systems as clearly endo-atmospheric and exo-atmospheric systems allows the Navy to use derivatives of the Standard Missile Block IV to take full advantage of the conditions associated with each of these operating zones. Use of an existing missile and ship system baseline also allows use of the existing interface structure to minimize cost. To counter the endo-atmospheric TBMs, the SM-2 BLK TVA upgrades include an advanced imaging infrared (IIR) seeker, an improved fast-reaction auto pilot and a forward looking RE all in the same volume as the existing missile. The highly responsive SM-2 Block IVA missile, complemented with Aegis weapons systems modifications, provides capability against enemy aircraft and cruise missiles, as well as TBMs. Standard Missile-3 (SM-3) replaces the SM-2 Block TV warhead, radar and guidance section with a boosted third stage and an advanced kinetic warhead (KW). Operation in the exo-atmospheric region permits a KW design with autonomous guidance control and divert thrusters for high maneuverability and has the capability of achieving very high interceptor velocities.

In an era of fiscal austerity, downsizing and unforgiving pressure upon human and economic capital, it is an Augean task to identify resources for fresh and creative work. The realities of the day and the practical demands of more immediate fleet needs can often dictate higher priorities. Yet, the Navy must avoid eating its seed corn. Exercising both technical insight and management foresight, the fleet, the R&D community, the Office of the Chief of Naval Operations (OpNav) and the product engineering expertise of the Naval Surface Warfare Center (NSWC) are joined and underway with integrated efforts to marry new, fully demonstrated technologies and operational urgencies. Defense funding today cannot sponsor all work that can be mission-justified over the long term because budgets are insufficient to support product maturation within the classical development cycle. However, by rigorous technical filtering and astute engineering of both marketplace capabilities and currently available components, it is possible in a few select cases to compress and, in effect, integrate advanced development (6.3), engineering development (6.4), weapon procurement (WPN), ship construction (SCN), operation and maintenance (O&M,N) budgetary categories when fleet criticalities and technology opportunities can happily meet. In short, 6.3 funds can be applied directly to ''ripe gateways'' so modern technology is inserted into existing troubled or aging systems, sidestepping the lengthy, traditional development cycle and accelerating practical payoffs to recurrent fleet problems. To produce such constructive results has required a remarkable convergence of sponsor prescience and engineering workforce excellence. The paper describes, extensively, the philosophy of approach, transition strategy, polling of fleet needs, technology assessment, and management team requirements. The process for culling and selecting specific candidate tasks for SHARP sponsorship (matching operational need with t

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

The objectives of Human engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine Technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.
