The World of Liquid-Crystal Display TVs—Past, Present, and Future

The full-fledge development for liquid-crystal display (LCD) technologies began aiming to achieve a ldquowall-mounting TVrdquo in the 1960 s. Since then, it has been more than 30 years from the birth of LCD product, the market of LCDs has grown above 10 billion dollars, and in the future, it is expected to further expand at a fast pace. The driving force in the current marketplace will be the original goal, ldquoLCD TVs,rdquo which contribute to drastically improving display performance of LCD and the evolution of LCDs. This paper, therefore, will focus on the LCD-TVs, and describe their history, the state-of-the-art of the technologies, as well as the prospect of their potential in the future.

The Semantic Grid: Past, Present, and Future

Grid computing offers significant enhancements to our capabilities for computation, information processing, and collaboration, and has exciting ambitions in many fields of endeavor. We argue that the full richness of the Grid vision, with its application in e-Science, e-Research, or e-Business, requires the "Semantic Grid." The Semantic Grid is an extension of the current Grid in which information and services are given well-defined meaning, better enabling computers and people to work in cooperation. To this end, we outline the requirements of the Semantic Grid, discuss the state of the art in achieving them, and identify the key research challenges in realizing this vision.

Thin Films: Past,Present, Future

Thin-film photovoltaics was developed as a means of substantially reducing the cost of photovoltaic (PV) systems. The rationale for this was that thin-film modules would be cheaper to manufacture owing to their reduced material costs, energy costs, handling costs and capital costs. However, thin films had to he developed using new materials, including amorphous silicon, copper indium diselenide, cadmium telluride and film crystalline silicon. In all cases, these technologies faced major technical and financial hurdles. The most crucial technical barriers are described within the text. Today, much progress has been made and the performance of the best thin-film laboratory cells approaches the best performance of polycrystalline silicon cells. Outdoor stability has been a problem, especially with amorphous silicon, but this material and newer thin films now display good to excellent stability. It appears that the goal of thin films—truly low-cost PV electricity that can be sold into energy-significant markets—can be achieved. However, its achievement will require both the continuing resolution of technical problems and the ongoing investment of significant public and/or private resources.     

Optical Networking: Past, Present, and Future

Over the past 25 years, networks have evolved from being relatively static with fairly homogeneous traffic to being more configurable and carrying a heterogeneous array of services. As the applications are ultimately the driver of network evolution, the paper begins with a brief history of circuit, packet, and wave services, along with the development of the corresponding transport layers. The discussion then moves to the evolution of network-node architecture, with an emphasis on the optical-electrical-optical and optical-bypass paradigms. Scalability and cost-effectiveness in meeting network demands are two key factors in the discussion. The evolution of networking equipment, along with the development of the optical control plane, has facilitated a configurable optical layer. The enabling technologies, along with their ramifications, are discussed. Finally, the paper speculates on how capacity might evolve in the future, to handle the undoubtedly new services that are on the horizon.

中国农村通信的今昔与未来

中国农村通信技术经历了从人工、机电到程控的逐步而漫长的发展过程,经营体制上也经历了一系列变迁,并长期保持国营、地方国营和集体所有制等多种体制并存的局面。目前虽然农村通信已经取得了长足进步,但广大的中西部,尤其是偏远地区、山区和海岛等电信发展水平还很低,并面临各种困难。建议建立普遍服务基金,建设农村综合信息传播网,采取无线和卫星等技术,促进农村通信的快速发展。

Power System Control Centers: Past, Present, and Future

In this paper, we review the functions and architectures of control centers: their past, present, and likely future. The evolving changes in power system operational needs require a distributed control center that is decentralized, integrated, flexible, and open. Present-day control centers are moving in that direction with varying degrees of success. The technologies employed in today's control centers to enable them to be distributed are briefly reviewed. With the rise of the Internet age, the trend in information and communication technologies is moving toward Grid computing and Web services, or Grid services. A Grid service-based future control center is stipulated.

The Development of the ATC Radar Beacon System: Past, Present, and Future

The ATC radar beacon system is a descendant, through an extended evolutionary development, of military identification friend or foe (IFF) systems begun during World War II. It is today's primary source of surveillance data for air traffic control and performs this function with a high degree of effectiveness. A number of programs are underway to correct its current deficiencies. Looking to the future, the further automation of air traffic control together with the projected growth of air traffic lead to requirements for improved surveillance and communication capability. A discreteaddress mode of beacon system operation, with integral ground-air-ground data link, is under development to meet these needs.

An Overview of Latin American Telecommunications, Past, Present, and Future

A historical perspective on the development of telecommunications in Latin America in the last decade is evolved in this introductory paper. The current national telecommunication situation is then considered with reference to three countries-Honduras, Colombia, and Brazil-with emphasis on planning and future programs. Because of the accelerating impact that satellite communication has had on Latin American telecommunications development, international, intercontinental, domestic, and regional satellite communication operation and plans are treated. Finally, some broad-gauge objectives for development and integration of Latin American telecommunications to provide economic growth and social and cultural benefits are presented.
