The eSleeve: a novel wearable computer configuration for the discovery of situated information
- Trang 793-796
Describes work in progress on wearable computing configurations which provide audio and visual output based on the position and orientation of the user. We introduce the 'eSleeve'-a wearable wrist computer with position and heading sensors combined with a user interface employing speech recognition and a small display. Applications described include searching a database of locations, and implement......

A fair admission control for large-bandwidth multimedia applications
- Trang 317-322
Current admission controls aiming to maximize network utilization create a bias against large-bandwidth calls. This paper proposes a BNP (buffer without preemption) model which will hold a call in a buffer rather than directly reject it when the residual bandwidth is insufficient. No other call can be admitted until this queued call is served. Such a mechanism increases throughput because the buff......

TWSAPI: a generic teamwork services application programming interface
- Trang 365-370
One of the problems faced by large, global organizations and enterprises is to effectively enable their employees to collaborate across locations. People need collaborative work support while they are on the move and have to share business documents and know-how. Although much work has been done in the area of computer supported collaborative work (CSCW) to date, supporting mobility is only recent......

Behavior and performance of message-oriented middleware systems
- Trang 645-650
The middleware technology used as the foundation of Internet-enabled enterprise systems is becoming increasingly complex. In addition, the various technologies offer a number of standard architectures that can be used by designers as templates to build applications. However, there is little concrete understanding in the software industry on the strengths and weaknesses of competing technologies, a......

Personal Web Space
- Trang 169-175
This paper describes the functional requirement and architecture of a software system called Personal Web Space (PWS). A PWS is a system to manage the information from the WWW, for either leisure or work related use. Similar to bookmarks, a PWS stores a set of URL addresses but, in addition, it caches on a proxy server pages of high interest. PWS is developed through an evolutionary process that i......

A transmission service with three-queue management for a distributed remote monitoring environment
- Trang 217-221
A high-speed fixed network is not suitable for a distributed remote monitoring environment because it lacks mobility. Therefore, wireless communication is another choice for transmission. This paper proposes a transmission service to classify the transmitted data into three kinds of transmission events. Three priority queues are used to receive the corresponding events and transmit these data acco......

Analytical performance prediction of WWW distributed cache management (DCM) protocols
- Trang 812-819
We introduce analytical models for predicting the performance of World Wide Web (WWW) proxy caches that are distributed over multiple proxy machines under various management protocol assumptions. The purpose of these models is to determine which distributed cache management (DCM) protocols are to be used for large-scale distributed caches. The accuracy and usefulness of our models is assessed by c......

An improved /spl alpha/-Shapes algorithm for geometric reconstruction
- Trang 228-232
Combining virtual reality and network multimedia techniques in applications is becoming popular. 3D geometry models are used in such applications. It is difficult to build mathematical models manually, but reverse engineering for building such models. Such a model is suitable for Internet transmission. However, there is still a bottleneck in using reverse engineering to reconstruct a relationship ......

Performance evaluation of mobile agent on its living time and target existing rates in servers
- Trang 341-346
The performance of a mobile agent in obtaining data is evaluated by computer simulation in terms of the number of mobile agents. As a preparation for the simulation, two parameters "target existing rate" and "living time" of the mobile agent are identified through experiment on the Internet. This paper suggests that these parameters are essential factors for distinguishing a suitable situation for......

A collaborative infrastructure for scalable and robust news delivery
- Trang 655-659
In this paper we describe the model used for the NewsWire collaborative content delivery system. The system builds on the robustness and scalability of Astrolabe to weave a peer-to-peer infrastructure for real time delivery of news items. The goal of the system is to deliver news updates to hundreds of thousands of subscribers within tens of seconds of the moment of publishing. The system signific......
