The DIG Description Logic Interface: DIG/1.1

This document describes a simple API for a general description logic system.

The DIG Description Logic Interface: DIG/1.0

This document describes a simple API for a general description logic system. This forms the first of a number of such specifications. Later versions will introduce more higher-level functionality. The current, Level 0 specification provides basic access to the reasoning capabilities of a DL reasoner.

Such stories arise at moments of changing equilibria in the processes of the social construction of reality. They are especially evident during periods of intense dialectic in which long held theses...

Reservoir geophysics

The concept of petroleum reservoir geophysics is relatively new. In the past, the role of geophysics was largely confined to exploration and, to a lesser degree, the development of discoveries. As cost-efficiency has taken over as a driving force in the economics of the oil and gas industry and as major assets near abandonment, geophysics has increasingly been recognized as a tool for improving...
