Sleepers awake! The Y2K Problem may or may not be a technological disaster. But either way, the aftermath of the technological problems will be legal problems. Litigation over who should have done what will include damage claims for failures of software and liability for failure to prepare. The legal problems will be a disaster costing potentially trillions of dollars. Once the frenzy of litiga...

While our Y2K worries about old computers "retiring" at midnight captured the television and news media attention, a more significant "old age" phenomenon snuck onto the scene with hardly a headline: the dawn of the age of the aged. (1) The over burdened health care system will face a worldwide wave of retirees who will live longer, cost more to treat, and demand new goods and services to help ...

Rising complexity within muti-tier computing architectures remains an open problem. As complexity increases so do the costs associated with operating and maintaining systems within these environments. One approach for addressing these problems is to build self-healing systems (i.e., frameworks) that can autonomously detect and recover from faulty states. Self-healing systems often combine machi...

We present high spatial resolution near–infrared H-band (1.65 μm) images, taken with ISAAC on UT1 of ESO VLT, of three radio-loud quasars at z∼1.5, as a pilot study for imaging of a larger sample of radio-loud and radio-quiet quasars in the redshift range 1 < z < 2. We are able to clearly detect the host galaxy in two quasars (PKS 0000-177 and PKS 0348-120) and marginally in the third (PKS 0402...

An experimental program is described in which the bending and longitudinal dynamics of structures simulating solid-propellant rocket motors are being studied. The structure is considered to be a cylindrical grain of solid propellant to which is bonded a thin steel case. Vibrations of the empty steel cylinder suspended in a free-free condition are studied first. Secondly, a similar steel cylinde...

Association rule mining is a computationally expensive task. Despite the huge processing cost, it is getting tremendous popularity due to the usefulness of the association rules. Several efficient algorithms can be found in the literature that cope with this popular task. This paper provides a comprehensive survey on the state-of-art algorithms for association rule mining, specially when the da...

It's not just mainframe-based applications: servers and workstations pose significant Y2K problem risks for organizations and individuals. R esolving the problem of y2k compliance is a serious issue for the distributed enterprise. As organizations rely on distributed desktops for decision making and productivity, the risks associated with noncompliant desktops are receiving increased attention ...

In this paper we wish to examine the phenomenon of Y2K as an instance of information systems failure. Taking this particular stance on the issue leads we feel to a number of interesting areas that demand further investigation. We first review the current phenomenon of Y2K and discuss some of the relevant work in the area of IS failure. The topic of IS failure has tended to concentrate on issues...

We have discovered molecular hydrogen in a fourth quasar damped Lyα system (hereafter DLA). The UVES spec-trograph on the 8.2m ESO Kueyen telescope has allowed the detection of H 2 in gas with low metallicity, Z/Z 10 −2 , and high neutral hydrogen column density, N (H i) 2.6 × 10 21 cm −2 , at redshift z abs = 3.3901 toward QSO 0000–2620. The measured H 2 fractional abundance of f (H 2) 4 × 10 ...
