In this instance,the Web browser will act as the user agent of the mailing system. With this,users will be able to compose, send and read video mail directly on the Web.This paper examines a number of different system architectures which can be employed for the development of Video Mail. Based on the following key issues:portability of system, flexibility of system, Internet standard support, securityand authentication, and message compression and storage, a final architecturewas chosen to build Video Mail. The approach taken is that the system will beinterfaced to the Web using a standard HyperText Transfer Protocol (HTTP)server and a standard Web browser. This is achieved through the use of Common Gateway interface (CGI) programs and forms which reside in a standard HTTP server to provide the functionality of video mail, and a separate mail server for the storage and management of messages. This will cause the HTTP server to behave as if it is an electronic mail system. The paper also addresses implementation issues pertaining to the use of CGI programs, mail server development, and video and audio composition and playback.展开更多

When an optimal number of random shortcuts are added to a regular neural chain, the system can reach a state which is nearly periodic in time and almost synchronized in space. More shortcuts do not increase the spatial synchronization too much, but will obviously destroy the temporal regularity.展开更多
