Abstract

This paper proposes a new Heterogeneous Multi‐hop Cellular IP (MCIP) network that integrates multi‐hop communication with Cellular IP. MCIP increases the coverage of the wireless network and improves the network robustness against adverse propagation phenomena by supporting communication in dead zones and areas with poor radio coverage. MCIP includes three components: location management, connection management and route reconfiguration. Location management is responsible for maintaining the location information for Mobile Stations (MSs) in a local domain. Connection management establishes an initial path for data transmission and a route reconfiguration mechanism is proposed to take advantage of various multi‐hop connection alternatives available based on terminal interfaces, network accessibility and topology. Our simulation results show that MCIP performs well in networks of various sizes including scalability, throughput, and packet delay.

Abstract

Construction of a new library for Brooklyn College required that the collections and staff move out of the existing library building. This move into temporary quarters necessitated that the library close its stacks. The author describes how the staff planned, implemented, and managed an on‐site as well as an off‐site paging system for approximately one million volumes. Practical administrative and management issues are discussed that could be applied to other libraries needing to plan a paging system for their library collections. The impact on library users is also discussed. The author concludes that paging systems may become commonplace as storage facilities become the new model for academic and research libraries.

Abstract

The computational efficiency of subspace iteration is addressed relative to the data structures adopted for the very large and generally sparse coefficient matrices. The frequent triangulations and matrix multiplications demand that access to the terms in the coefficient matrices be unbiased. Reliance on virtual memory (paging) operating systems with no special considerations for localized data access is not adequate. Specific data structures must be designed that accommodate the needs of the numerical algorithm yet eliminate unnecessary paging. An implementation of the subspace iteration method using hypermatrix data structures is presented. Use of hypermatrices is shown to provide unbiased and localized data access. The various modifications to the conventional formulation are described and an example problem illustrates the potential benefits of the hypermatrix formulation. Possibilities for adapting hypermatrix data structures to new supercomputer architectures are discussed.

Abstract

Examines competitiveness of national newspapers and how their competitiveness with regard to pagination provides a comprehensive study. Considers whether or not the newspaper industry is a declining industry, and gives many examples with circulation figures to argue against this. Sates that there is more need to understand more fully the factors interrelating with the pagination of newspapers, both in the long and short‐terms. Breaks down the production process of a newspaper with direct costs and specifications. Discusses policies, constraints, long term revenue and cost factors, plus others affecting pagination.

Abstract

Discusses the various mobile communication systems made available by modern technology. Examines the nature and potential of various systems: paging, cellular radio, CT2/Telepoint, and Personal Communications Networks. Concludes that successful mobile communication depends on recognition of its importance in business, market awareness, requirements, compatibility, choosing reputable suppliers, and monitoring future developments.

Abstract

Non‐mediated, patron‐initiated inter‐library loan recently became a new component of OhioLINK, a consortium of Ohio academic libraries in both the public and private sectors ranging from major research institutions to community colleges. “Inter‐institutional lending” is used in this article to denote the process by which Miami University Libraries' patrons request items from other OhioLINK libraries. Pre‐implementation speculation, post‐implementation experiences, and control mechanisms showcase how “inter‐institutional lending” is leading to Ohio's dream of a virtual library.

Abstract

The software virtual machine (SVM) concept is described as a methodology to reduce the manpower required to implement and maintain finite element software. A SVM provides the engineering programmer with high‐level languages to facilitate the structuring and management of data, to define and interface process modules, and to manage computer resources. A prototype finite element system has been successfully implemented using the SVM approach. Development effort is significantly reduced compared to a conventional all‐FORTRAN approach. The impact on execution efficiency of the SVM is described along with special procedures developed to minimize overhead in compute‐bound modules. Planned extensions of capabilities in the SVM used by the authors are outlined.

Abstract

Discusses Sri Lanka’s deregulation of its telecommunication sector and how its government opened doors for private sector participation. Uses 7 Tables to aid in further explanation of how conditions were in helping the private sector operators, foreign investment, cellular mobile telephone operators, fixed access network operators and the interconnections of networks. Concludes Sri Lanka’s telecoms network needs major upgrading and development, but even so Sri Lanka is well on its way to being the Asia‐Pacific’s more progressive market member.

Abstract

The user interface, in broad terms, is the medium through which the user and the information come together. The types of searches a public access catalog (PAC) can perform are defined by the indexing strategy and retrieval software. The way the user's interest is communicated to the retrieval software and the way the results are communicated to the user is, by a more narrow definition, the interface software. Both the kinds of searches that can be performed by a variety of CD‐ROM PACs and how their workstations are used to accomplish the searches are considered.
