Abstract

In modern computer networks, agent-based systems are widely used. The very fundamental usage of agents are for management systems e.g. supporting SNMP-based databases and multiple client-server communications. This paper describes the Pay&Require mechanism implementing a multi-agent approach for a QoS-enabled computer network. The unique features of the P&R system are its comprehensive approach to the cooperation of agents dedicated to traffic monitoring, the selective response to the QoS-oriented admission of user requests, event-driven reconfiguration and transmission quality brokerage. The brokerage in quality purchase was based on different models – from a simple reactive agent to an agent with learning capabilities. The presented approach uses auctions in which agents (brokers) can buy quality parameters according to customer requirements. The use of auctions allows the dynamic pricing of data transmission services.

383 13.1 Introduction Computer networks may be a new technology that shifts the production function. Our previous research (Atrostic and Nguyen 2005) found a pos- itive and significant relationship between computer networks and labor productivity in U.S. manufacturing, using the first survey data on the pres- ence of computer networks in manufacturing plants, collected in the 1999 Computer Network Use Survey (CNUS). We controlled for other inputs to production, plant characteristics, and the endogeneity of computer net- works. However, because no data to proxy

Today, teleoperation over the computer network, like the Internet, is getting reality. Although today´s network technology provides us many useful features to realize teleoperation system, it´s time-varying communication delay makes force-reflecting bilateral feedback system unstable. Communication delay over the computer network also makes performing a task difficult, especially when the remote environment changes dynamically.

In this paper, first, we propose an alternative teleoperation system which could realize force-reflecting bilateral feedback over the computer network with varying time delay. Then we propose environmental predictive teleoperation system for manipulation of dynamic environment.

The proposed systems are implemented on experimental master-slave manipulator system and experimental results illustrate the validity of the system.

The cold warmth of communication in computer networks1 Richard W. Janney 1. Introduction: Digital writing? [ : - ( ] They that make them shall be like unto them. 113th Psalm According to Vilem Flusser (1989), communication in computer networks via written words will someday be a thing of the past — a relic of the tran- sitional period between alphabetical and digital writing. Flusser argues that in coming decades, if we wish to understand interaction with, and through, computers, it will become necessary to turn away from written language, and learn new

Biomedizinische Technik (ÖGBMT), Österr. Ges. für Medizinische Physik (ÖGMP) 1. Introduction Aged people who live alone are in particular need of a daily health check, medication, and warm communication with family and friends. Thus a human-friendly communication System is essential for the physical and mental care of aged people. To achieve human-friendly communication with a personal Computer
