Geological noise removal in geophysical magnetic survey to detect unexploded ordnance based on image filtering

This paper describes the application of three straightforward image-based filtering methods to remove the geological noise effect which masks unexploded ordnances (UXOs) magnetic signals in geophysical surveys. Three image filters comprising of mean, median and Wiener are used to enhance the location of probable UXOs when they are embedded in a dominant background geological noise. The study ar...

Telehealth in remote Northern Territory: bridging the gap.

Experiences of non-resident nurses in Australia's remote Northern Territory.

INTRODUCTION There is emerging concern in the health literature about the impacts of non-resident work modes on the quality of service delivery particularly in sparsely populated or remote areas, but little is known about what non-resident health workers themselves see as the advantages and disadvantages of their modes of work, and whether non-resident workers face the same or different social/...

Geophysical Identification and Geological Implications of

The southern Alaska magnetic trough (SAMT) is one of the fundamental, crustal-scale, magnetic features of Alaska. It is readily recognized on 10 km upward-continued aeromagnetic maps of the state. The arcuate SAMT ranges from 30 to 100 km wide and extends in two separate segments along the southern Alaska margin for about 1200 km onshore (from near the Alaska/Canada border at about 60 degrees n...

An integrated geological, hydrogeological and geophysical approach

This work sets out a physical-stratigraphical reconstruction of the superficial aquifer in the Brindisi area; this site is recognized to be at significant environmental risk (Law no. 426/98) by the Italian government. Geological, hydrogeological and geophysical methodologies were applied. The geological characterisation consisted of surface 5 and subsoil surveys. The existing stratigraphical, g...
