    What were the origins of radio? Who first suspected or believed that there were electromagnetic waves? Who first demonstrated that such waves could actually be brought into existence? Who was first to show that it was possible to communicate using these waves? The author shows that in trying to find out, the answers to those questions are far from clear cut View full abstract»

  • If only we'd known sooner [innovation projects, change management]

    Developing a new product may involve entering new markets, acquiring new distribution channels, or developing new customer service capabilities. Identifying these activities and interpreting how these activities relate to the organization's strategic identity are two separate problems. Problems easily confused by innovation managers. New product development requires, first, analysis of new markets and/or new technologies to identify what new activities would be required for implementation. Second, the activities must be featured in a process of interpretation that asks whether these proposed activities can and should be synthesized into the firm. The potential of organizational change to derail an innovation project suggests that management focus on avoiding unforeseen changes. Three techniques for managing innovation-driven change are given in the literature: (1) capture change requirements early; (2) do not allow change requirements to derail a project; and (3) minimise the change requirements by developing products that cultivate existing firm capabilities. So how do innovators and managers learn about change requirements? How do organizations manage change initiatives that innovation projects instigate? The study we did explored these questions by detailing exactly how 51 innovation-driven change initiatives are managed in 13 innovation projects in two Fortune 500 companies View full abstract»

  • Department performance metrics-a manager's viewpoint

    If we view the engineering design activity as a process, and we want to improve that process, then we need a way to measure its results and the trend of those results over time. At the Aeronutronic Division of Lockheed Martin Corporation, we developed and used a set of engineering performance metrics which helped guide our productivity and quality improvement efforts in the Mechanical and Electronic Design Departments. This article describes what we did, how we did it, and offers some advice based on our experience View full abstract»

  • Holographic optical data storage

    The evolution of holographic optical memories has followed a path not altogether different from holography itself. P.J. van Heerden is widely credited for being the first to elucidate the principles behind holographic data storage in a 1963 paper. The science and engineering of such a storage paradigm were heavily pursued thereafter. This resulted in many novel holographic multiplexing techniques for dense data storage and advances in holographic recording materials. Despite this progress, without technologies such as compact laser sources and optical data I/O devices, hope diminished for viable commercial products. Successful use of holography in other arenas rekindled interest in holographic data storage in the late 1980s. With many critical optoelectronic device technologies now in place, holography is once again considered a possible data storage solution View full abstract»

  • Cable modem technology

    Cable TV network's ability to provide fast data transmission using cable modems is receiving much attention these days. A cable modem (or cable TV modem) is a device that connects your computer to the cable TV network. The cable television (CATV) industry was born in 1948 as a way to provide TV reception to remote viewers. However, CATV's marriage to television basically obscured the fact that it can provide high-speed two-way data communication services. A cable modem is a modem in the sense that it MOdulates and DEModulates signals. However, a cable modem is far more complex than a typical telephone dial-up modem. A cable modem is partly modem, partly bridge, partly router, partly encryption/decryption device, partly NIC card, and partly Ethernet hub. A single cable modem connection speed is about 500 kbp-1.5 Mbps, and is used for point-to-point. The distance can be 100 km or even more View full abstract»

  • FIR and IIR digital filters

    A digital filter is a basic building block in any digital signal processing (DSP) system. The simulation results presented show how finite bit precisions can affect the performance of a digital filter. IIR filters are shown to be even more susceptible to finite bit precision effects than FIR filters. However, these effects can be reduced using the IIR filter with a cascaded structure View full abstract»

  • Electro-explosive devices

    Explosives are an integrated part of our technical infrastructure. They do not need to be used in large quantities to produce their desired effects. Explosives can be applied in small quantities to produce useful mechanical or chemical stimuli. To use an explosive in an application, the explosive needs some form of external stimulation. This stimulation can come in the form of a mechanical force, heat energy or an electrical signal. In this article, we will examine devices that are initiated by electrical stimulus-electro-explosive devices (EEDs). The author begins by considering what EEDs are and the various types of them. He goes on to discuss initiation mechanisms View full abstract»
