Acoustic emission (AE) source localization has been used to visualize progress failures generated in a wide variety of materials. In the conventional approaches, AE algorithms assume that signal is propagated as straight line. However, it supposed form heterogeneity elastic wave velocity distributions. Hence, with localization, expected accuracy reduced heterogeneous materials since diffraction...

Cited non-source documents such as articles from regional journals, conference papers, books and book chapters, working papers and reports have begun to attract more attention in the literature. Most of this attention has been directed at understanding the effects of including nonsource items in research evaluation. In contrast, little work has been done to examine the effects of including non-...

Map data are usually derived from a source that is based on a particular scale of representation and hence are subject to a particular degree of map generalization. Attempts to display data at scales smaller than the source can result in spatial con ̄ict, whereby map symbols become too close or overlap. Several map generalization operators may be applied to resolve the problem, including displac...

The sensory basis of the navigational map remains one of the most important and intriguing questions in animal behaviour. In birds, odours have been hypothesized to provide the primary source of map information. Convincing tests have shown that experienced homing pigeons rely on map information obtained at sites where they are exposed to natural odours, even if subsequently released (without ad...

Current developments within the information technology industry are creating new opportunities for traditional information suppliers such as Ordnance Survey. In particular the ability to electronically trade information creates opportunities to increase the use of Ordnance Survey’s topographic information in ways that can be go beyond the delivery of such data in the form of a map. The future d...

This paper discusses ongoing research into the construction of action adventure maps akin to those found within classic Nintendo series The Legend of Zelda. Following existing work in the composition of missions and spaces for the action-adventure genre, this work adopts these methods into a open-source 2D tile-based game with similar mechanics and tropes to that of the Zelda series.

There is a trend to acquire high accuracy land-cover maps using multi-source classification methods, most of which are based on data fusion, especially pixel-or feature-level fusions. A probabilistic graphical model (PGM) approach is proposed in this research for 30 m resolution land-cover mapping with multi-temporal Landsat and MODerate Resolution Imaging Spectroradiometer (MODIS) data. Indepe...

A method for the identification of alpha-helices in electron-density maps at low resolution followed by interpretation at moderate to high resolution is presented. Rapid identification is achieved at low resolution, where alpha-helices appear as tubes of density. The positioning and direction of the alpha-helices is obtained at moderate to high resolution, where the positions of side chains can...
