An integrated distance learning system capable of supporting interactions for asynchronous distance learning
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 116-121
In recent years, as the demand grows for taking lectures without the limitation
of time and place by those who have jobs and require life-long education,
expectations are increasing for the implementation of a distance learning
system. However, in most existing asynchronous distance learning systems, the
images shown on screen are limited to images of the teacher with synchronized
digital document...

Multimedia communication environment for children, handicapped, and elderly people
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 122-127
We have developed a multimedia communication environment for children and
handicapped and elderly people. This environment, named "F-Communication
system," is based on self-explanatory components and multiple interfaces. It
allows users to manipulate components and send multimedia messages using only
mouse clicks. Self-explanatory components for communication and an overview of
two interfaces of t...

A flexible, privacy-preserving authentication framework for ubiquitous computing environments
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 771-776
The proliferation of smart gadgets, appliances, mobile devices, PDAs and sensors
has enabled the construction of ubiquitous computing environments, transforming
regular physical spaces into "Active Information Spaces" augmented with
intelligence and enhanced with services. This new exciting computing paradigm
promises to revolutionize the way we interact with computers, services, and the
surroundi...

Stability of autonomous decentralized flow control schemes in high-speed networks
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 63-68
Focuses on flow control in high-speed networks. Each node in the networks
handles its local traffic flow only on the basis of the information it knows,
but it is preferable that the decision-making of each node leads to high
performance of the whole network. To this end, we investigated the behavior of
packet flow when a node is congested, and show an appropriate flow control model
through simulat...

Superphony: towards ubiquitous audio communication services
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 728-731
With the expansion of mobility in communication technologies, the increasing
individual audio solicitations require a definition of priorities in audio
information. A new concept called superphony is identified which improves
communication abilities by reconstructing an audio sphere around each user and
filtering audio information based on user and environment profiles. Requirements
and elements f...

Minimizing protocol processing in multimedia servers - implementation and evaluation of network level framing
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 149-155
Data servers for multimedia applications like news-on-demand represent a severe
bottleneck, because a potentially very high number of users concurrently
retrieve data with high data rates. In the Intermediate Storage Node Concept
(INSTANCE) project, we develop a new architecture for media-on-demand servers
that maximizes the number of concurrent clients a single server can support.
Traditional bot...

Scene context dependent key frame selection in streaming
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 208-213
In this paper, we describe the development of our scene context dependent key
frame selection method to reduce the amount of recorded video data. We propose
the use of motion analysis (MA) to adapt to scene content in our key frame
selection process. Based on the information generated by the motion analysis
stage, frames in the video sequence which contain significant motion information
are select...

Coordination architecture for evolvable event-based systems
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 571-572
Event-based and publish/subscribe systems provide levels of flexibility and
agility that bring us much closer to what is required for operating in business
environments that are "time critical". It is essential that the evolution of
systems be driven in terms of the business concepts that underlie the
requirements for change or determine the dynamics of service procurement, and
not the lower level...

Intrinsic references in distributed systems
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 675-680
The notion of intrinsic references, i.e. references based on the hash digest of
the referent, is introduced and contrasted with that of physical references,
where the referent is defined relative to the state of a physical system. A
retrieval mechanism using intrinsic references, the Elephant Store, is
presented. The use of intrinsic references in hierarchical data structures is
discussed, and the...

Progressive HTML for proximate and automatic interactions
Proceedings 22nd International Conference on Distributed Computing Systems Workshops - - Trang 723-727
Development and projections in the field of PDAs and wireless communication
architectures let us consider new applications which exploit short range and
direct exchanges. In a close future we may imagine mobile users equipped with
wireless PDAs dynamically and spontaneously exchanging rich information in an ad
hoc manner In such a context, a connection between two PDAs may be broken at any
time be...
