NUMERICAL EVALUATION OF SPECIFIC ABSORPTION RATE IN HUMAN HEAD AND TORSO FOR WEARABLE WIRELESS DEVICES IN UNDERGROUND MINE SCENARIOS.

The radiofrequency field levels may increase in confined environments, such as underground mines, due to reflections from inner boundaries (walls and arches). This study investigated the specific absorption rate (SAR) in the head and torso of a miner wearing a wireless device in underground mine scenarios. Two high-resolution voxel models were used to analyse the effects of a tunnel structure, a metal arch and a safety helmet at 2.

Modeling Spatio-temporal Malaria Risk Using Remote Sensing and Environmental Factors.

Background: Remote sensing have been intensively used across many disciplines, however, such information was limited in spatial epidemiology.

Methods: Two years (2009 & 2010) Landsat TM satellite data was used to develop vegetation, water bodies, air temperature and humidity criterion maps to model malaria risk and its spatiotemporal seasonal variation. The criterion maps were used in weighted overlay analysis to generate final categorized malaria risk map.
