nD modelling: Industry uptake considerations
Purpose â The purpose of this paper is to identify the key enablers and obstacles to the effective adoption and use of nD modelling technology.
Design/methodology/approach â This paper explores the feasibility of industry absorbing and diffusing nD modelling technology by considering key technology transfer issues; namely, organisational direction, inter-organisational networks and the knowledge characteristics of technology. Findings from semi-structured interviews around a diagnostic technology transfer framework are used to offer implications for theory and practice.
Findings â The results from 15 survey interviews indicate that construction professionals appreciate the potential significant benefits of nD modelling technology, but at present, nD modelling technology is seen as too embryonic; too far removed from construction firms' âcomfort zonesâ; requiring too much investment; and, containing too many risks.
Originality/value â The paper stresses that the challenge for nD modelling technology, along with any new technology, is to shift from its âtechnology pushâ emphasis, to a more balanced âmarket orientatedâ stance, which allows the technology to be shaped by both strategic design concerns, and day-to-day operational needs. If this trajectory is pursued, nD modelling technology could have a positive future
Diverter Decision Aiding for In-Flight Diversions
It was determined that artificial intelligence technology can provide pilots with the help they need in making the complex decisions concerning en route changes in a flight plan. A diverter system should have the capability to take all of the available information and produce a recommendation to the pilot. Phase three illustrated that using Joshua to develop rules for an expert system and a Statice database provided additional flexibility by permitting the development of dynamic weighting of diversion relevant parameters. This increases the fidelity of the AI functions cited as useful in aiding the pilot to perform situational assessment, navigation rerouting, flight planning/replanning, and maneuver execution. Additionally, a prototype pilot-vehicle interface (PVI) was designed providing for the integration of both text and graphical based information. Advanced technologies were applied to PVI design, resulting in a hierarchical menu based architecture to increase the efficiency of information transfer while reducing expected workload. Additional efficiency was gained by integrating spatial and text displays into an integrated user interface
Coupling Constants for Scalar Glueball Decay
We evaluate the partial decay widths of the lightest scalar glueball to pairs
of pseudoscalar quark-antiquark states. The calculation is done in the valence
(quenched) approximation on a 16^3 \time 24 lattice at . These
predictions and values obtained earlier for the infinite volume continuum limit
of the scalar glueball's mass are in good agreement with the observed
properties of and inconsistent with all other observed meson
resonances.Comment: 8 pages of Latex, 12 PostScript figures, 2 macros included, plenary

Matching the High Momentum Modes in a Truncated Determinant Algorithm
Within a truncated determinant algorithm, two alternatives are discussed for
including systematically the remaining ultraviolet modes. Evidence is presented
that these modes are accurately described by an effective action involving only
small Wilson loops.Comment: LATTICE98(algorithms) ; typos correcte
