    Will the Columbia catastrophe prove to have been an "accident" in the strict sense of the word? The author discusses the causes of the Challenger disaster and possible causes of the Columbia disaster. The steps that led to the Columbia disaster-paved, like the road to hell, with good intentions and judgments that each in isolation look acceptable-are still being worked out. Only then will we be ab... View full abstract»

    Private companies and standards bodies are straining to somehow boost the performance of the two chief last-mile broadband technologies: digital subscriber lines (DSLs), which send data over telephone wires, and cable modems, which use TV cables. A further extension of ADSL2, known as ADS L2+ and also expected to win ITU approval, promises to double the data rates of today's technology to 25 Mb/s ... View full abstract»

  • Legacy phone networks get new lease on life: a telecom evolution caters to data demands

    Publication Year: 2003, Page(s):18 - 20
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (403 KB) | HTML iconHTML

    Perhaps the biggest technical problem facing telephone companies all over the world is the growing mismatch between their networks' capabilities and customer demands. Nowhere is this mismatch more glaringly apparent than in the companies' struggle to keep pace with the steady growth of Internet traffic. Pure data now exceeds voice traffic nearly everywhere, over the legacy phone systems designed d... View full abstract»

    Discusses developments which offer scenarios that, to some military strategists, would justify the use of nuclear weapons. The sorts of nuclear weapons likely to figure into war planners' recommendations are much smaller than those designed to wipe out entire cities, and they would be targeted at hardened, isolated military installations. Broadly speaking, nuclear weapons fall into two categories.... View full abstract»

    Digital technology continues its march from media like CDs and DVDs toward your audio speakers. Today, amplifiers based on digital principles are already having a profound effect on equipment efficiency and size. They are also beginning to set the standard for sound quality. What distinguishes Class D amplifiers from all others is that their power transistors are always operated either fully on or... View full abstract»

    The author describes how hackers broke new ground the weekend of 24-26 January 2003 with an unusual type of Internet attack. While most computer worms propagate by e-mail, Slammer spread over the Internet among servers and even corporate PCs running such programs as the premium version of the Office XP software suite. The afflicted computers all ran software containing Microsoft's database program... View full abstract»

    Humidity in the air trapped between the outer skin of the plane and the interior bulkheads condenses, then freezes during high-altitude flight, and melts on landing. The water causes malfunctions in electrical systems and corrodes the aircraft fuselage, soaks insulation, and, after enough flights, adds to the plane's load. A Swedish aerospace company, CTT Systems AB (Nykoping), aims to stop the da... View full abstract»

    The process of getting a US patent goes something like this: you work with your patent lawyer or agent to prepare an application that describes your invention in exhaustive detail; the Patent Office rejects all of your claims in curt, dismissive terms; your counsel says not to panic and, in most cases, persuades the patent examiner to allow at least some claims; and, finally, two or more years aft...

    Plans are being finalized to encase the Chernobyl Reactor 4 in the worlds largest movable structure, a 20000-ton steel shell so large that indoor rain is a serious design consideration. The shell will serve two purposes, to keep [radioactive] dust in and rain out. The structure is meant to cover the old sarcophagus for the next 100 years, while over 200 tons of uranium, nearly a ton of plutonium, ... View full abstract»

    Flash is under assault by technologies bent on proving they can do better. These upstart random access memories (RAMs) have little in common. The ferroelectric memory picks up on the electric fields inside certain atoms and the directions in which they point. The magnetoresistive type stores data as the either-or directions of the alignment of small magnetic regions in a ferromagnetic material. A ... View full abstract»

    Computers that harness the weirdness of quantum mechanics could smash conventional encryption systems by factoring gigantic numbers fast-and factoring the product of two large prime numbers is the only way standard codes can be broken. The job would take conventional computers decades, not minutes. Encrypted data is still safe for the moment, because a powerful enough quantum computer is still man... View full abstract»
