    For pt.2 see ibid., vol.22, no.2 (2003). The article discusses the significant technology advances which have encouraged the development of the digital computer. The transistor effect, discovered at Bell Laboratories in 1947, helped make digital computers truly practical. Advances in semiconductor technology, through integrated circuits and microprocessors, resulted in the minicomputer, microcompu... View full abstract»

    Today's new generation of undersea cable systems extensively uses optical amplifiers, which allows the systems to be implemented over transoceanic distances. Optical amplifiers offer significantly increased transmission capacity, networking functionality and operational flexibility - all potentially at lower cost than traditional regeneration systems. Thus, similar techniques are now being used in... View full abstract»

    The need to provide reliable high data rate communication over the wireless channel has led to the development of efficient modulation and coding schemes. Diversity (time, frequency, space, polarization, angle) is an effective method to combat fading and improve the link reliability of the wireless channel. Time and frequency diversity lead to loss in bandwidth efficiency. However, by employing mu... View full abstract»

    Even though many US technological achievements are born elsewhere, decisions that affect the future viability of all types of engineering are made regularly on Capitol Hill (Washington, DC). In fact, public policy has an enormous impact on the direction of the careers of engineers. From the impact of research and development allocations to global competitiveness stemming from our national industri... View full abstract»

    "Homeland security" continues to be the hot buzz phrase that does not seem to be cooling down anytime soon. A 5 June 2003 joint memorandum from the US White House Office of Science and Technology Policy (OSTP) and the US Office of Management and Budget (OMB) was issued to the heads of executive departments and agencies. The goal was to provide guidance on how to prioritize R&D programs as these he... View full abstract»

    As optical link speeds get faster, demands for performance and embedded network services impose increasing flexibility demands. Internet routers must become more efficient and programmable. A new hardware architecture using a dynamic reconfigurable logic (DRL) circuit, along with its design methodology, is proposed. Our approach is to allocate all resources using the dynamic reconfigurable control... View full abstract»

    The article looks at how engineers can be trained in decision making. It provides a practical four-step approach to the decision making process. The first step is to know what has to be decided. Then the options or alternatives available must be set out. The third step is to obtain the information needed to make the decision and know what criteria to use to select the relevant information. Finally... View full abstract»

    Antenna arrays are individual radiating elements combined so that they function and perform like a single large antenna. Besides high radiating beam directionality, antenna arrays offer the capability to scan the main beam and control sidelobe radiation electronically. Retrodirective antenna arrays, as the name suggests, have a special feature. When receiving a signal from an unspecified direction... View full abstract»

    Increasingly, there is concern that the environment for conducting excellent research is deteriorating within the United States' large public research laboratories. This worry is being voiced both by the rank and file scientists within these institutions, as well as by leaders responsible for stewarding the US research infrastructure. The article describes a study which is limited to assessing the... View full abstract»

    The steady down scaling of CMOS device dimensions has been the main stimulus to the growth of microelectronics and computer aided very large scale integration (VLSI) design. But the more an integrated circuit (IC) is scaled, the higher its packing density becomes. The increasing size of chips, measured in either area or number of transistors, and the waste of the large capital investment involved ... View full abstract»
