Ray shooting from convex ranges

We consider geometric and graph-theoretic aspects of the well-known paradigm \killing two birds with one stone". Consider that we have a set X of n-points in space and a compact plane convex set S. We deene a graph G(X; S), called the ray shooting graph, on X as follows: The points of X are the vertices and fpi; pj g, pi; pj 2 X , is an edge if and only if the line joining pi to pj intersects S...

Weathering of lead bullets and their environmental effects at outdoor shooting ranges.

Lead contamination at shooting range soils is of great environmental concern. This study focused on weathering of lead bullets and its effect on the environment at five outdoor shooting ranges in Florida, USA. Soil, plant, and water samples were collected from the ranges and analyzed for total Pb and/or toxicity characteristic leaching procedure (TCLP) Pb. Selected bullet and berm soil samples ...

Temporary changes in hearing after exposure to shooting noise.

OBJECTIVES Firearm is a common source of impulse noise that may potentially damage hearing organ. It has been suggested that otoacoustic emissions, particularly transient-evoked otoacoustic emissions (TEOAE), might be more sensitive than pure-tone audiometry (PTA) in the assessment of changes to cochlea caused by noise. The aim of this study was to: (i) evaluate exposure to impulse noise from s...

Occupational exposure to impulse noise associated with shooting.

Shooting training is associated with exposure to a considerable amount of unique noise. We wanted to evaluate noise exposure during such training. Our observations especially apply to professional sport shooters, but they are also valid for shooting coaches/instructors. We collected acoustic signals in 10-, 25- and 50-m as well as open-air shooting ranges. The recorded material was analysed wit...

An efficient model for prediction of underwater noise due to pile driving at large ranges

Modelling the sound levels in the water column due to pile driving operations nearby and out to large distances from the pile is crucial in assessing the likely impact on marine life. Standard numerical techniques for modelling the sound radiation from mechanical structures such as the finite element (FE) and boundary element method are not well suited to predict the sound field efficiently at ...
