This paper presents the evaluation results of two student surveys on a collaborative examination process using asynchronous learning network (ALN) for a graduate-level course at NJIT. The exam process includes students making up questions, picking out questions, answering, grading and appealing the grades. The process was conducted on the Virtual Classroom/sup R/ and Webboard/sup R/ during the fall 1999 and spring 2000 semesters, with some revision of the process in the second semester. The surveys following each exam elicited feedback from 138 students. Results show the majority of students felt they learned throughout the process, the exams were successful in demonstrating what they learned, and it was an enjoyable process. Students' concerns and our experiences are presented as well as suggestions for future research on this topic.

The U.S. Coast Guard is in the concept exploration phase of its Integrated Deepwater System (IDS) acquisition project. This project will define the next generation of surface, air and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) assets used to perform the Coast Guard's missions in the IDS environment (>50 NM off the U. S. coastline). As part of early technology investigations, the needs exist to: (1) analyze the workload requirements of the IDS, (2) identify alternative means to perform ship's work, and (3) optimize ship manning consistent with ship workload, performance criteria, and the available tools and equipment aboard. To reduce shipboard work requires an understanding of the mission and support requirements placed on the vessel and crew, how these requirements are currently met, and how requirements might otherwise be met to reduce workload and crew size. This study examined currently implemented workload and manpower reducing approaches of commercial maritime fleets, U.S. and foreign navies, and foreign coastguards. These approaches were analyzed according to evaluation criteria approved by the IDS acquisition project team. From this, strategies for shipboard work reduction that may be considered for adoption by the IDS were identified and analyzed according to performance and costs factors. Ten workload-reducing strategies were identified: damage control, bridge, multiple crewing, engineering, risk acceptance, modularity, deck, enabling technologies, ship/personnel readiness, and operability and maintainability.

Hierarchical WWW cache formation which provides both higher hit rates and saves overall bandwidth consumption through fetching WWW objects and periodically redistributing them among member caches is proposed as an application on a satellite Internet infrastructure. With regular prefetching and distribution of WWW objects, our system can utilize the satellite Internet with continuous streaming data transmissions for efficient WWW caching. Our system consists of a single hub cache and several rim caches. The hub cache is a core unit which is located at the satellite hub station and gathers WWW objects from the Internet, while the rim cache fetches requested WWW objects from the hub cache as well as receiving WWW objects pushed from the hub cache. The prefetching strategy of the rim cache is based on the statistical pattern analysis of user accesses. Traffic monitoring is used to manage both prefetching and object push operations. In order to reduce the consumption of bandwidth in the satellite Internet, multicast transmission of WWW objects is introduced. Furthermore, cached objects are checked regularly with an ''if update' tag so that their consistency can be maintained with reasonable overhead. We discuss our design and implementation of the AI3 CacheBone with our adaptive hierarchical WWW cache formation scheme. Through experiments, we show that the performance of our rim cache shows an improvement of approximately three fold when compared with ordinary hierarchical cache systems such as Squid. © 1999 IEEE.

The past twenty-five years has been marked by the introduction ed marine environmental regulations that have had a profound effect on how ships are designed, built and operated. Ships being designed and built today must accommodate not only current regulations but anticipate those enacted over their thirty to fifty year life cycles. U.S. Chief of Naval Operations, Office of Environmental, Safety and Health (CNO N45) has articulated a vision for the Environmentally Sound Warship of the Twenty-first Century. This vision incorporates the "Sense of Congress" for a naval ship designed to operate in full compliance with environmental regulations worldwide. The task of the Navy engineering team is to translate this vision into reality;a ship capable of prevailing in time of war and able to conduct operations in all areas of the globe, unencumbered by special procedures for environmental compliance. The keys to this warship design are the early integration of environmentally sound principles, materials, and processes into the ship acquisition process;minimization of both hazardous materials and generation of post shipboard consumer waste during operation;adaptation of integrated systems to reduce the volume of wastes and enhance processing efficiency;reduced manpower requirements;and crew indoctrination in environmental protection.

Modelling combat system manning and manpower reduction

引用

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 153-171页

作者： Roos, CH Carl H. Roos:is a Senior Engineer with Logicon-Syscon. A graduate of the University of Pittsburgh with a BSEE degree he has over 35 years experience in functional operational combat system fire control interface and computer program design. As technology changed and the combat system was upgraded Mr. Roos maintained his level of technical expertise by taking graduate-level courses in computer science modelling & structured analysis networking & fiber optics. He has worked in various capacities on the LHD LHA DDG 993 DD 963 LPD 17 LCC LPD 13 CGN 38 CGN 9 CG 26 and the DDG Class Combat Systems. In recent years Mr. Roos has been responsible for managing directing and performing engineering design and analysis efforts associated with Battle Management Organization (BMO) functional analysis and operational analysis. These efforts were used in defining combat system operational requirements shipboard space requirements and integration requirements. His paper “Configuration Management of Digital Programs” was published at the 1972 IEEE Southeastern Conrence.

NAVSEA 03K41 is responsible for generating Combat System Rattle management Organizations (BMO) and Functional Flow Diagrams (FFD). Several years ago, NAVSEA provided the resources to conduct a functional analysis that would support the development and validation of the BMOs and FFDs. The major obstacle in performing the analysis was obtaining a consensus on how the functional hierarchy was to be structured. The non-optimum organization of the hierarchy was selected;as a result, the functions were difficult to define, find, use, and validate. Recognizing the shortcomings of this effort, research was conducted to evaluate state-of-the-art structured modelling techniques, concepts, and methodologies. Two modelling concepts by James Martin were found to be applicable for the combat system functional analysis: Enterprise Modelling Concept and Functional Decomposition Modelling Concept. The Structure Modelling definitions of Whitten, Bently, and Barlow provided the guidelines for using the Martin concepts. During the ensuing BMO and FFD development efforts, a Ship's Combat System (SCS) Modelling concept evolved and a SCS Model was developed. This paper addresses how the modelling concepts and tools are used in the BMO and FFD development and validation process. Data from the SCS Model provides the basis for defining combat system requirements (e.g., software, data display, database, networking, etc.).

Ship design is often multidisciplinary involving several design elements with various types of objectives and constraints (O/C) some easily described as mathematical formulas, others better modeled as descriptive assertions. This paper describes a method based on fuzzy functions and an integrated performance index to model O/C using descriptive assertions to be used with mathematical formulas in optimization. Another issue addressed in this paper concerns the coordination of design elements when sequentially coupled, that is, when one leads the other and the performance of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the method described here coordinates and optimizes sequentially coupled elements. The two methods are applied to machinery arrangement (MA) and pipe routing (PR). Preliminary models for optimization of MA and PR are described considering convenience, producibility: engine room size, interference and location as factors in the O/C set. Some test results from MA/PR applications are presented and discussed. The methods are generic and can be extended to other elements in ship design. They are mutually independent and may be used separately Two advantages of their use are an improvement in overall performance and a reduction in the need for redesign of elements.

The Defense Advanced Research Project Agency (DARPA), in conjunction with the U.S. Navy, initiated a research program for the design and construction of a distinctive warship for the 21st century known as the Arsenal Ship. By using an innovative development and acquisition approach it was hoped to streamline the procurement process and reduce costs. In an environment where budgets are being cut, both industry and Government were challenged to develop, design, and produce the innovative ship and related mission systems to meet specific performance capabilities within strict affordability constraints. A key element of this innovative acquisition approach was a new certification scheme designed to replace the traditional test and evaluation (T&E) and acceptance process. The purpose of this paper is to describe the development of the certification plan during Phase LI of the Arsenal Ship program by the American Bureau of Shipping and the contending Shipyard teams, and to discuss the potential benefits of this alternative certification approach. Although the Arsenal Ship program was canceled late in 1997, insight derived from the exploration of new certification concepts could benefit future design and building programs.

Consider a pyramid with n levels and a k-dimensional hypercube, 0/spl les/k/spl les/2n-2. The paper presents a parallel algorithm for embedding large pyramids into smaller hypercubes with load balancing. With dilation 4, congestion at most 2/sup n-k/2/+4, and load [2/sup 2n-k//3] when k is even, our algorithm embeds the pyramid into the hypercube, otherwise, with the same dilation and load, it has congestion 2/sup n-(k+1)///sup 2+1/+6 when k is odd. The algorithm can be performed in O(k)-bit time.
