MAWC Operations for the Growing Book
We describe the conceptual framework for the Growing Book, which is an ever-expanding body of knowledge created by a team of experts, and the basic operations such as Match, Abstract, Weave and Customize, which can be used to extract and organize information from the multi-level, multimedia, multi-lingual book.

Multi-level specification and protocol design for distributed multimedia communication
The major challenge in the design of an efficient distributed multimedia system is the integration and support of a wide variety of applications. Investigating the basic issues involved in the design and specification of distributed muttimcdia systems is the focus of this paper. A basic layered network architecture is proposed as the uniform framework for the investigation of different levels of functionality typically associated with the communication network that supports multimedia communication. Within this framework, we propose to identify the communication requirements for multimedia applications and characterize a set of communication primitives which specify different qualities of scrvicc to reflect different real-time rcquircmcnts. ‘Ilis investigation is guided by an efficient and flexible multi-level specification model. We will characterize this model and show that the model can be amenable to the construction of a set of communication primitives that support synchronization and communication of multimedia applications.

Iconic language design for people with significant speech and multiple impairments
We present an approach of iconic language design for people with significant speech and multiple impairments (SSMI), based upon the theory of Icon Algebra and the theory of Conceptual Dependency (CD) to derive the meaning of iconic sentences. An interactive design environment based upon this methodology is described.

Extending Visual Languages for Multimedia
Visual languages, which let users customize iconic sentences, can be extended to accommodate multimedia objects, letting users access media dynamically. Teleaction objects, or multimedia objects with knowledge structures, can be designed using visual languages to automatically respond to events and perform tasks like "find related books" in a virtual library.

Accessing and Browsing Information and Communication
This book contends that accessing and browsing information and communication are multidimensional and consequential aspects of the information user's entire experience and of general human behavior. Problems in information creation, processing, transmittal, and use often arise from an incomplete conceptualization of the "information seeking" process, where information seeking is viewed as the intentional finding of specific information. The process has traditionally been considered to begin with some kind of search query and end with some kind of obtained information. That, however, may be only the last, most easily observable--and perhaps not even primary--stage of a complex sequence of activities.This book reviews related theory, research, practice, and implications from a wide range of disciplines. It also analyzes converging forms of information, including mass media, online information services, the Internet and World Wide Web, libraries, public spaces, advertisements, and organizational communication. Extensive case studies illustrate the theoretical material.

A two-dimensional vector packing model for the efficient use of coil cassettes
We consider the problem of efficiently packing steel products, known as coils, into special containers, called cassettes for shipping. The objective is to minimize the number of cassettes used for packing all the given coils where each cassette has capacity limits on both total payload weight and size. We model this problem as a two-dimensional vector packing problem and propose a heuristic. We also analyze the worst-case performance of the proposed algorithm under a special condition which, in fact, holds for the particular real-world case that we handled. Our computational experiment with real production data shows that the proposed algorithm performs quite satisfactorily in practice.

SIMD architecture for job shop scheduling problem solving
Job shop is a typical environment for manufacturing high-variety and low-volume discrete parts. Good scheduling is critical and challenging to the competitiveness of job shops. The Lagrangian relaxation neural network (LRNN) provides an approach of quantifiable quality and successful industrial applications. To further speed up scheduling for large-scale problems, in this paper, the parallelism of the LRNN approach is exploited for hardware implementation. New designs include a SIMD architecture, its associated instruction set and detailed circuits. Logic level simulation of the circuit design shows consistent schedules with those obtained by a software implementation. The hardware implementation is expected to have a one to two orders speed-up over the software one.

A Delphi examination of public sector ERP implementation issues
A Delphi survey of ERP life cycle management issues was conducted within five agencies of the Queensland government. The five agencies each implemented SAP Financials at around the same time using the services of a common implementation partner. Responses were elicited from ERP project participants, from managers at the agencies, and from users of the financial systems. Valid questionnaires were returned from 61respondents in the first round survey (response rate = 55%) and yielded 274 perceived issues. Through two rounds of the Delphi survey, these issues have been summarized and categorized into 10 major issue categories (with 38 sub-issues). The final survey round in which respondents will assign weights to these issues is currently underway. Lessons drawn from this study will assist in understanding the ERP life cycle and specific characteristics of the public sector ERP life cycle, and will provide insights into the strengths and weaknesses of ERP systems for public sector organizations.

The design of a secure and pervasive multimodal Web system
While most users currently receive Web services from Web browser interfaces, pervasive computing is emerging and offering new ways of accessing Internet applications from any device at any location (Satyanarayanan, 2002; Estrin et al., 2002), by utilizing various modes of interfaces to interact with their end users. The PC and its back-end servers remain important in a pervasive system, and the technology could involve new ways of interfacing with a PC and/or various types of gateways to back-end servers. In this research, cellular phone was used as the pervasive device for accessing an Internet application prototype, a multimodal Web system (MWS), through voice user interface technology (Anerousis and Panagos, 2002). This paper describes how MWS was designed to provide a secure interactive voice channel using an Apache Web server, a voice server, and a Java servlet engine. It was also shown that multimodal user-interface pages can be generated by using XSLT stylesheet which transforms XML documents into various formats including XHTML, WML, and VoiceXML.
