Important links between the infrastructure components and the emerging national standards are shown     

The changing face of US telecommunications trade policy

The author discusses the widely held belief that the US trade deficit as a whole and the telecommunications trade deficit in particular are due in large part to a perceived disparity between the US policy of promoting free trade and the allegedly protectionist policies adopted by foreign countries. Against this backdrop, he reviews a revealing exchange of correspondence between Federal Communications Commission Chairman Dennis Patrick and House Telecommunications Subcommittee Chairman Edward Markey that goes to the core of these issues

基于智能视觉的动态人脸跟踪

传统方法中对动态人脸识别采用的是单演局部主方向编码识别,通过分块子模式的加权融合进行人脸特征提取,因为人脸表情和姿态变化会导致识别结果出现误差。在智能视觉模式下,提出一种基于信息熵子模式主成分分析的动态人脸跟踪识别方法。基于特征状态空间重构方法,将人脸图像分成大小相等的子模块,对子模块进行信息熵特征提取,采用主成分分析方法进行人脸特征分类。仿真结果表明,采用该算法进行动态人脸跟踪识别,能有效实现人脸表情动态跟踪,人脸识别性能较好、精度较高,性能优于传统算法。     

The evolution of telecommunications technology

The telephone network today is the result of many years growth. Technology has enabled this growth to occur, and simultaneously allowed a steady reduction in the real cost of service and an increase in the level of performance. Technology will continue to facilitate the economic growth of the network, and with the evolution to digital will enable a much larger variety of information to be carried. Managing this broad range of capabilities requires more than traditional hardware and even software technologies. The real leverage will come from a broader class of "'soft" technologies that goes beyond language and operating systems to encompass system architecture, protocols, and databases. This paper will address the potential evolution of the network with respect to both hard and soft technologies. The trends in these technologies and in the network itself are leading towards a high-performance transport layer, with added intelligence layers to define the transport capabilities for a variety of services.

The telecommunications industry in Taiwan

Telecommunications in Taiwan dates back more than 100 years and is provided by a government-owned organization. With the worldwide trend of liberalization and globalization of the telecom business, Taiwan cannot isolate itself from the international arena and must face the challenge of increased competition. The author first introduces the current status of the telecommunications industry in Taiwan, and then describes some technical innovations and a series of policies implemented by the government. In addition, telecom service projects and future prospects are also presented     

The Croatian telecommunications way toward the communications era

Previous years have brought interesting developments in the field of telecommunications all over the world. Countries in transition have experienced it in their own way. Croatia is an interesting example of such a country. After gaining independence in 1991 and setting course toward the open market economy, the development of telecommunications was particularly fast. Related legislative changes as well as changes in the ownership structure of Croatian telecom will surely have a significant impact on the future development of telecommunications in Croatia, which will be based on our own experiences as well as the experiences of other countries in transition and developed countries. The planning methodology will include the techno-economic evaluation of minimum-risk introductory routes for new services as defined within the European Union projects. An overview of the development of Croatian telecommunications during the '90s as well as plans for future development are presented. A comparison with other countries in development as well as with developed countries is given, too. A survey of the development of telecommunications within the County of Split and Dalmatia, including economic aspects, is given. An overview of research and development activities is also given     

The future of computer telecommunications integration

Describes activities in integrating the desktop computer with the telephone system (computer-telephony integration, or CTI). CTI is but one step in the evolution to a seamless and interoperable integrated telecommunications and computer infrastructure, and this may arrive surprisingly soon, enabled by some recent technological developments     

The political economy of telecommunications regulation

This paper analyzes the effects of government regulation on the pricing and supply of telecommunications services in the United States. Among other things, it considers the effects of current economically inefficient pricing policies on bypass of the public switched telephone network and the widespread availability of low-cost telephone service, as well as the impact of the Bell System divestiture and other government policies on the economic organization of production in the industry. It examines how the regulatory environment is likely to change over the next decade, the forces making for change (or lack thereof), and the prospects for consumer-welfare-enhancing reform.     

The evolving role of telecommunications switching

The impact of technology changes on the capabilities of telecommunications switching systems is discussed. It is argued that to obtain a combination of rapid response to market needs, ultra-high network integrity, and continued choice of software and hardware providers, network operators will move toward the increased use of distributed communications, computing, and management environments, using a slowly evolving core transport layer and a rapidly evolving services layer in their network architectures. The emergence of broadband in the mass market will challenge physical designers to use innovative physical technologies in large switches to realize the needed interconnects and to control power consumption and dissipation. Declining transmission costs and powerful database technologies will continue to push the trend toward fewer numbers of larger switches and increased utilization of network reconfiguration at the path and facilities level

The challenge of the VLSI technique to telecommunications systems

The rapid evolution from the transistor to the LSI circuit revolutionized telecommunications systems. In particular, the low-cost IC's triggered the transition from wired- to stored-program control and from analog to digital techniques by introducing standard IC's as microprocessors, memories, etc. The availability of analog-digital interface circuits, for example codecs, filters, SLIC's, and vocoders, has become very important. In addition to the technical revolution, the economical aspects must be considered. LSI circuits enter more and more into the vicious circle of greater complexity-fewer applications and thus higher costs. An escape from this circle is offered by programmable circuits such as microprocessors or new circuits with a regular architecture. Nevertheless, custom circuits will always be used in order to protect the system know-how. The blend of standard and custom circuits will be important for the success of a systems house. Since vertical integration activities will be unlikely, different concepts of cooperation between IC manufacturers and system house become more and more important.
