Unifying Distributed Processing and Open Hypertext through a Heterogeneous Communication Model

A successful distributed open hypermedia system can be characterised by a scaleable architecture which is inherently distributed. While the architects of distributed hypermedia systems have addressed the issues of providing and retrieving distributed resources, they have often neglected to design systems with the inherent capability to exploit the distributed processing of this information. The research presented in this paper describes the construction and use of an open hypermedia system concerned equally with both of these facets

An Open Framework for Integrating Widely Distributed Hypermedia Resources

The success of the WWW has served as an illustration of how hypermedia functionality can enhance access to large amounts of distributed information. However, the WWW and many other distributed hypermedia systems offer very simple forms of hypermedia functionality which are not easily applied to existing applications and data formats, and cannot easily incorporate alternative functions which would aid hypermedia navigation to and from existing documents that have not been developed with hypermedia access in mind. This paper describes the extension to a distributed environment of the open hypermedia functionality of the Microcosm system, which is designed to support the provision of hypermedia access to a wide range of source material and application, and to offer straightforward extension of the system to incorporate new forms of information access

Orthodontic Treatment of a Congenitally Missing Maxillary Lateral Incisor

Clinicians agree that, regardless of gender or race, tooth agenesis has become more prominent in recent societies. The congenital absence of one or more maxillary lateral incisors poses a challenge to effective treatment planning for the restorative dentist. However, the one-sided orthodontic approach of just moving canines mesially to eliminate restorative procedures leads to compromise. Adult patients presenting with malocclusions, missing lateral incisors, or anterior crowding but who fail to get proper orthodontic treatment, requesting instead esthetic solutions that do not establish a stable occlusion, proper alignment, and proper axial inclination of the teeth will have compromised esthetic and periodontal results. An evaluation of anterior smile esthetics must include both static and dynamic evaluations of frontal and profile views to optimize both dental and facial appearance. This article presents how orthodontics is combined with other specialties in treating a congenitally missing lateral incisor. One case is used to illustrate how orthodontic treatment is progressed in collaboration with other specialists

A Framework for Distributed Open Hypermedia

Early hypermedia systems are now referred to as closed systems due to their reliance upon proprietary document formats, embedded links, monolithic designs and their inability to integrate with the desktop environment. Advances from the research community gave rise to a new generation of open hypermedia systems. Open hypermedia systems tend to have modular architectures and can offer an extensible hypermedia link service integrated with the desktop environment. One explanation for the unmitigated success of the World Wide Web (WWW) is the way in which common Internet services have been integrated. Although the WWW is open in terms of the platforms and protocols supported, it has several limitations in common with closed hypermedia systems. Described in this thesis is Microcosm TNG, a framework for distributed open hypermedia, able to integrate with both the desktop and the Internet. The abstraction of a hypermedia application is introduced for improving the organisation and the encapsulation of related documents and link services. Such a resource can then be made available to remote users via the Microcosm TNG framework. Architectural extensions to the system are described which enable the hierarchical composition of hypermedia applications to construct rich distributed information spaces

Enriching Audio Support In A Hypermedia System

Many hypermedia systems support a wide variety of media such as text, video and pictures, but audio has been somewhat neglected. The central reason that audio has not attracted as much attention as other media is its obvious lack of visual identity. The visual nature of window-based applications, especially window-based hypermedia viewers, meant that the main focus of this work was to identify a meaningful representation of audio within a hypermedia context. This paper introduces the sound viewer and describes the associated concepts. The issues raised during development are also discussed in some depth. This viewer facilitates the creation and traversal of links to and from sound media. The audio media formats supported are WAV[1], CD[2] Audio and MIDI[3]. The resultant viewer provides a unified and extensible framework for interacting with audio media operating from within a open hypermedia environment. Microcosm is the product of research into open hypermedia systems conducted by a group within the department. Microcosm can be augmented to support additional media with minimal overhead. This is largely attributable to the open design of the system which is consequently an ideal experimentation vehicle for the sound viewer design
