Is Concept of Sustainability Utopian: Ideally Perfect but Impracticable?

Black Box Anomaly Detection: Is It Utopian?

Automatic identification of anomalies on network data is a problem of fundamental interest to ISPs to diagnose incipient problems in their networks. ISPs gather diverse data sources from the network for monitoring, diagnostics or provisioning tasks. Finding anomalies in this data is a huge challenge due to the volume of the data collected, the number and diversity of data sources and the divers...

[A non-alcoholic Society is too Utopian].

Framing the elusive concept of sustainability: a sustainability hierarchy.

Usage of the word "sustainability" is widespread and incorporates a plethora of meanings. After reviewing four extant sustainability frameworks, we propose a Sustainability Hierarchy to structure a broad array of issues that have been associated with sustainability. These issues vary widely in their urgency, severity and uncertainty of consequences, and temporal and spatial dimensions. It categ...

Probability is perfect, but we can't elicit it perfectly

The challenge problems set out in Oberkampf, Helton, Joslyn, Wojtkiewicz and Ferson (this issue), hereafter referred to as OHJWF, raise a variety of interesting questions. The background to this workshop is the continuing growth in number, diversity and complexity of computer simulation codes being built to model a huge variety of important real-world systems. Users of such models are increasin...

What is an `ideally imperfect' crystal? Is kinematical theory appropriate?

Most materials are crystalline because atoms and molecules tend to form ordered arrangements, and since the interatomic distances are comparable with the wavelength of X-rays, their interaction creates diffraction patterns. The intensity in these patterns changes with crystal quality. Perfect crystals, e.g. semiconductors, fit well to dynamical theory, whereas crystals that reveal the stereoche...
