The author observes that the social fabric of engineering, the support infrastructure of the profession, and the political and economic systems of the world are undergoing shifts that affect what engineering is, how it is accomplished, and what it should do. He asks what these changes mean in terms of the educational system and explores a few of these issues that lie between academia and the industrial environment beyond. He discusses the engineering curriculum as seen from industry, the role of continuing education, research in academia 相似文献

"电路原理"与"信号与系统"课程的整合与优化 总被引:4,自引:2,他引:2
科学技术迅速发展,新兴学料不断增加,知识总量不断增长,迫使本科教育不断向着基础化方向发展,基础课程教学在本科教育中的地位愈来愈高。计算机技术的广泛应用,离散信号与系统的基础知识已是电气类各专业的必要的教学内容。因此基础课程要从根本上整体优化课程结构。本文提出了电气类专业“电路原理”与“信号与系统”课程教学改革方案,将两门课程教学内容进行整合与优化,并在实际教学过程中进行了教学试验,缩短了教学时间,提高了教学质量。 相似文献

The deposition of silicon carbide thin films and the associated technologies of impurity incorporation, etching, surface chemistry, and electrical contacts for fabrication of solid-state devices capable of operation at temperatures to 925 K are addressed. The results of several research programs in the United States, Japan and the Soviet Union, and the remaining challenges related to the development of silicon carbide for microelectronics are presented and discussed. It is concluded that the combination of α-SiC on α-SiC appears especially viable for device fabrication. In addition, considerable progress in the understanding of the surface science, ohmic and Schottky contacts, and dry etching have recently been made. The combination of these advances has allowed continual improvement in Schottky diode p-n junction, MESFET, MOSFET, HBT, and LED devices 相似文献

Over the last 40 years in the semiconductor industry, one of the most reliable truths has been that "thepath forward is through integration." Moore's law and its various derivatives and cousins have illustrated how greater integration has provided tremendous benefits in cost, power, size, and performance. While shrinking process lithography has been a critical enabler of this trend, we should remember that tremendous innovation in device technology, circuits, system architecture, computer aided design (CAD), packaging, and many other areas have been necessary as well. The exponential integration phenomenon has not been limited to memory and microprocessors: mixed signal and radio functions have also seen striking advances in integration over the last 20 years, from cell phones to wireless LANs, integrated "systemon-a-chip" (SOC) transceivers have become prevalent in the circuits conferences, journals, and - in some applications - have even made it into commercial mainstream products. 相似文献

目前所谓的全光网络一般指基于DWDM传送技术的光传送网络(OTN)。由于OTN的节点采用OADM和OXC技术,为解决目前点到点的DWDM技术在应用中不能实现灵活组网和当网络失效时不能有效进行保护的问题提供了一种解决方法,使得OTN具有传输容量大、组网灵活、网络具有可扩展性和可重构性、易于升级等特点,可透明传输具有代码格式的不同速率等级的用户数字信号,能够同时适应用户信号种类用服务种类不断增长的需求。 相似文献

Cellular architecture partitioning can improve the performance of telecommunications systems. The model proposed by the author allows for changing the cell size for different services and the number of users. The cell size that will ensure the best possible performance and quality of service can be derived by the model. The main task of a telecommunication system is call processing. This includes identifying incoming calls, establishing a communication path for the duration of the connection, and disconnecting the call after the conversation has ended. Call processing uses different components of the software architecture and involves processes and messages performing different functions and accessing various resources. In addition, the system requires administration and maintenance that also involves processes using different resources 相似文献
