作者： Hamilton, Charles S. Program Executive Officer for Ships REAR ADMIRAL HAMILTON is a native of Amityville New York. He attended Duke University graduating in May 1974 with a bachelor of science in zoology. He was commissioned in the Navy in May 1974 through the NROTC Program at Duke. Rear Adm. Hamilton's sea tours include electronics material officer and combat information center officer in USS Hawkins (DD 873) (1974 to 1976) fire control officer and missile officer in USS Coontz (DDG 40) (1976 to1978) operations officer in USS Callaghan (DDG 994) (1981 to 1984) executive officer USS Fox (CG 33) (1986 to 1988) and commanding officer USS O'Brien (DD 975) (1991 to 1993). Rear Adm. Hamilton's shore tours include anti-submarine warfare program analyst and administrative assistant to director Program Resource Appraisal Division (OP-91) Office of the Chief of Naval Operations (1984 to 1986) head Aegis Destroyer Section (OP-355F) and financial coordinator Aegis Cruiser Destroyer Branch Office of the Chief of Naval Operations (1988 to 1990) and military staff specialist for naval war-fare in the Office of the Under Secretary of Defense (Acquisition and Technology) (1994 to 1996). In May 1996 Rear Adm. Hamilton became program manager for the arsenal ship which was designed to provide massed precision fires in support of Fleet commander's warfighting requirements. After completing the first two design phases and passing significant acquisition reform lessons learned to the DD 21 Program Office Rear Adm. Hamilton closed down the Arsenal Ship Program in March 1998. From April 1998 to February 2000 Rear Adm. Hamilton served as deputy for Fleet in the Program Executive Office Theater Surface Combatants (PEO TSC-F). In this position he was responsible for Fleet Introduction and Lifetime Support of 120 surface combatants (DDG 51 CG 47 DDG 993 DD 963 FFG 7). Rear Adm. Hamilton served as program executive officer for Surface Strike (PEO (S)) from February 2000 until November 2002. As PEO (S) he managed the Zumwalt-class DD 21/DD (X) N

The challenges which stood as an obstacle to the naval force development are discussed. The main challenge in the national security environment is to be virtually available anywhere in the world at the behest of the national command. It is observed that in surface warefare coast guard has the most applicability and expansion of their surveillance area will help in engaging other vessels away from the manned platform. It is also observed that the relationship with mission modularity and the growth between the coast guard and the navy has attracted interest among the international community.

Due to a widely use of XML language in various application domains, a well-established mechanism for the definition and enforcement of security controls on specific accesses to XML documents is demanded, in order to ensure that only authorized entities can perform certain actions on the protected data. The proposed rule-based, declarative approach supports definition of (possibly implicit and complex) authorization rules on particular nodes within a document as well as enforcement of multiple user-defined policies, specifying selected mechanisms to resolve conflicts or to apply default authorization. Moreover, by founded on both RDF and XDD theory, the developed approach yields a simple yet flexible and interchangeable XML access control model with well-defined declarative semantics. © Springer-Verlag Berlin Heidelberg 2003.

This paper proposes a new method to determine the types of function for approximating line segments using an algorithm based on binary search. In the function approximation-based image coding, it is essential that the joint points between different types of line segment be extracted precisely. Through experiments, it is verified that the proposed method extracts straight lines and arcs more precisely than the earlier method.

This paper discusses a method to determine the optimal node location before a long distance FWA network (22 GHz band, 6.3 Mbit/s) is set. During our 3 years experiment, we found out that the long distance FWA net with 2 links (about 60 km) was down for approximately 42 hours per year due to heavy rain fall conditions. This means that the long distance FWA net is practicable to some extent. We discuss a method to estimate the working ratio between two unknown locations using AMeDAS weather data. By using this method, an appropriate node location can be decided before FWA net is deployed. This approach can improve the working ratio in the sense of link-up continuation.

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.

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.

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.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.
