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......

Quản lý di động trong mạng nhiều lớp dựa trên IP hỗ trợ dịch vụ truyền thông đa phương tiện di động Dịch bởi AI
- Trang 347-352
Giao tiếp không dây chỉ cung cấp giọng nói là không đủ để đáp ứng nhu cầu của người sử dụng. Đó là một tính năng quan trọng của giao tiếp không dây thế hệ tiếp theo để cung cấp khả năng này thông qua Internet di động. Mobile IP cho phép các thiết bị di động thay đổi vị trí và giảm khả năng mất gói dữ liệu trong các mạng giao tiếp không dây. Tuy nhiên, Mobile IP vẫn còn một số thiếu sót trong các k......

Whoops!: a clustered Web cache for DSM systems using memory mapped networks
- Trang 806-811
We present Whoops!, a clustered Web cache prototype based on SciFS, a distributed shared memory (DSM) that benefits from the high performances and the remote addressing capabilities of memory mapped networks like Scalable Coherent Interface (SCI). Whoops! uses the DSM for all Web cache management and cache storage. Using a memory mapped network and a DSM programming model allows us to investigate ......

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......

Coordination architecture for evolvable event-based systems
- 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......

Event-driven coordination of real-time components
- Trang 589-594
The coordination paradigm has been used extensively as a mechanism for software composition and integration. However, relatively little work has been done for the cases where the software components involved have real-time requirements. The paper presents an extension to a state-of-the-art controller event-driven coordination language with real-time capabilities. It then illustrates the expressive......

The impact of data aggregation in wireless sensor networks
- Trang 575-578
Sensor networks are distributed event-based systems that differ from traditional communication networks in several ways: sensor networks have severe energy constraints, redundant low-rate data, and many-to-one flows. Data-centric mechanisms that perform in-network aggregation of data are needed in this setting for energy-efficient information flow. In this paper we model data-centric routing and c......

The design of interactive negotiation agent on the Web
- Trang 176-181
Because of the growth of Internet commerce, individual online transactions will grow rapidly. So in this paper we propose an interactive negotiation agent system on the Internet to help buyers make decisions. We use multi-attribute utility theory as the basic decision making strategy and the theorem is useful for the multicriteria decision. We stated the user goal that can be divided into several ......

Subscription summaries for scalability and efficiency in publish/subscribe systems
- Trang 619-624
A key issue when designing and implementing largescale publish/subscribe systems is how to efficiently propagate subscriptions among the brokers of the system. Brokers require this information in order to forward incoming events only to interested users, filtering out unrelated events, which can save significant overheads (particularly network bandwidth and processing time at the brokers). In this......

A framework for connecting home computing middleware
- Trang 765-770
In the future, microprocessors will be embedded in various appliances such as home appliances, digital AV appliances, and personal appliances. These appliances will be connected to various types of networks, such as Internet, and communicate with each other The communication of appliances would integrate some services provided by these appliances and make new services. The future home computing en......
