This paper interrogates the socio-spatial environment that is emerging in Singapore with its development of a globalised economy. Using the case studies of two of the city’s dichotomised spaces – the spectacular downtown and gentrified heartland – the paper seeks to examine the resulting spatial reconfigurations, challenges and unintended consequences. While the common assertion is that state-l...

Luckily, not many storms are as destructive as Katrina. Since 1990, only Hurricane Andrew approaches it in the value of property damage, which was less than half that of Katrina in 2005 dollars. The attacks of September 11, 2001, did a comparable amount of property damage, but cost far more lives. That such catastrophes are extremely rare does not necessarily mean another will not occur in the ...

The goal of this paper is to report the results of a comprehensive statistical analysis of the urban wireless channels, based on WCDMA field-measurements data. The applications of our study are in the area of WCDMA-based mobile phone positioning. The target here is the analysis of the Line-of-Sight (LOS) and Non Line-of-Sight (NLOS) situations and of the statistical distributions of their param...

This paper examines the positioning accuracy of a GSM beaconbased location system in a metropolitan environment. We explore five factors effecting positioning accuracy: location algorithm choice, scan set size, simultaneous use of cells from different providers, training and testing on different devices, and calibration data density. We collected a 208-hour, 4350Km driving trace of three differ...

Samples of the chrysotile taken during and after treatment by the wet dispersion process have been tested for their cytotoxic effect in vitro and the results compared with both a UICC chrysotile A sample and a dust prepared from a standard chrysotile textile yarn. Results were obtained from three different in vitro assay systems utilizing P388D1, V79-4 and A549 cells. A sample which still conta...

Recent research suggests that the hippocampus is not needed for the maintenance and recovery of extensively used environments learned long ago. Instead, a network of neocortical regions differentially supports memory for locationnavigation knowledge and visual appearance of well-known places. In this study, we present a patient, S. B., who was diagnosed with probable Alzheimer's disease long af...
