Recent findings in the domain of combining classifiers provide a surprising revision of the usefulness of diversity for modelling combined performance. Although there is a common agreement that a successful fusion system should be composed of accurate and diverse classifiers, experimental results show very weak correlations between various diversity measures and combining methods. Effectively n...

In this paper we study the wedge disclination within the elastoplastic defect theory. Using the stress function method we found exact analytical solutions for all characteristic fields of a straight wedge disclination in a cylinder. The elastic stress, elastic strain, elastic bend-twist, displacement and rotation have no singularities at the disclination line. We found a modified stress functio...

In Malaysia, rock slope stability analysis has been largely confined to kinematic with mass rating systems as assessment tools for analysis. While this method addresses the fundamental issues of including identifying potential failure modes, an information gap still exists between geologists and engineers in designing proper mitigation measures slopes. This paper aims address issue by incorpora...

Phylogenetic analysis of bacteria preserved within an ice wedge from the Fox permafrost tunnel was undertaken by cultivation and molecular techniques. The radiocarbon age of the ice wedge was determined. Our results suggest that the bacteria in the ice wedge adapted to the frozen conditions have survived for 25,000 years.

The wedge and left atrial pressures were compared in 1'2 subjects with congenital and aequired heart disease; all experiments were carried out with closed chest under basal conditions. A poor correlation between the wedge and left atrial pressures was mnoted in over half the patients. The wedge pressure is especially inaccurate in mitral stenosis with marked elevations in left atrial pressure.

BACKGROUND/AIMS The stepped-wedge cluster randomised trial design has received substantial attention in recent years. Although various extensions to the original design have been proposed, no guidance is available on the design of stepped-wedge cluster randomised trials with interim analyses. In an individually randomised trial setting, group sequential methods can provide notable efficiency ga...
