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...

Combining region-based differential and matching algorithms to obtain accurate motion vectors for moving object in a video sequence
- Trang 202-207
Motion estimation plays an important role in image processing, since temporal
information has been regarded as a promising feature for both image segmentation
and video coding. In this paper a hybrid approach is proposed to integrate a
differential (gradient-based) optical flow approach and region-based matching
approach to search for accurate object motion vectors. Our method adopts the
Horn-Schu...

Modeling of train control system and a method of assurance evaluation
- Trang 89-94
Assurance technology is a general term for technology that utilizes a system
which considers the two elements of heterogeneity and adaptability. There are
various needs in railway systems, so assurance properties are also being sought
for train control systems. Coexistence of heterogeneous systems and adaptability
for smooth system replacement are sought within daily operational changes. In
this p...

Adaptive checkpointing for time warp technique with a limited number of checkpoints
- Trang 95-100
This paper discusses distributed checkpointing with "Time Warp techniques", a
typical uncoordinated checkpointing technique that is often used in the parallel
and distributed simulations. Relaxing the assumption of the previous model of
Soliman et al., we show a discrete time model where the number of available
checkpoints each process can hold is finite. In addition, we propose an adaptive
distri...

QoS control of multimedia communication over wireless network
- Trang 336-340
In this paper QoS control of a real-time multimedia communication system under
heterogeneous environments of wired and wireless networks is proposed. In our
suggested system, as channel coding the FEC (forward error correction) method
with Reed-Solomon coding is introduced to reduce the packet error rate on the
wireless network. On the other hand, as source coding, transcoding methods
including tr...

Predicate matching and subscription matching in Publish/Subscribe systems
- Trang 539-546
An important class of publish/subscribe matching algorithms work in two stages.
First, predicates are matched and then matching subscriptions are derived. We
observe that in practice, the domain types over which predicates are defined are
often of fixed enumerable cardinality. Based on this observation we propose a
table-based look-up scheme for fast predicate evaluation that finds all matching
pr...

A demand based algorithm for rapid updating of replicas
- Trang 686-691
In many Internet scale replicated system, not all replicas can be dealt with in
the same way, since some will be in greater demand than others. In the case of
weak consistency algorithms, we have observed that updating first replicas
having most demand, a greater number of clients would gain access to updated
content in a shorter period of time. In this work we have investigated the
benefits that ...

Đặc tả và xác minh các yêu cầu chất lượng trong các trình bày đa phương tiện phân tán Dịch bởi AI
- Trang 323-328
Các ứng dụng truyền phát liên tục có một khía cạnh tạm thời ngụ ý, tức là chúng
được trình bày với một tỷ lệ nhất định trong một khoảng thời gian nhất định và
nếu tỷ lệ trình bày yêu cầu không được đáp ứng, tính toàn vẹn của các phương
tiện này sẽ bị phá hủy. Chúng tôi trình bày một tập hợp các cú pháp ngôn ngữ phù
hợp cho việc định nghĩa QoS cần thiết và khía cạnh thời gian thực của các phương

Using aspect oriented programming to build a portable load balancing service
- Trang 473-478
Scaling applications to large networks and an increasing number of users has
been for years a technical challenge. Today, technologies are well known to
scale applications to local networks but scaling to large networks with high
latency is still a challenge. The DLBS (dynamic load balancing service) brings
new solutions regarding large scale load balancing for middleware based
applications. DLBS ...

A replica distribution method with consideration of the positions of mobile hosts on wireless ad-hoc networks
- Trang 331-335
One of the features of wireless ad hoc network technology is that networks can
be constructed without a fixed network infrastructure. Communication in a
disaster is one application of a mobile ad hoc network. Data on the disaster can
be collected by mobile hosts. The mobile hosts can then exchange data to decide
rescue priority, etc. However connectivity in a wireless ad hoc network is not
guarant...
