The formulae developed in the preceding chapters all refer to light sources which can be regarded as a point constituting the apex of a solid angle). The derivations have each time been based on the cone-shaped propagation of the luminous radiation, i.e. on the inverse square law.

Point-Source and Non-Point-Source Problems Affecting Seabird Populations
1992Industrial pollutant discharges and oil spills currently represent the principal point-source hazards to seabird populations. Several examples of severe disruptions to localized colonies include the near extirpation of brown pelicans and double-crested cormorants in southern California by DDT; gull, tern, and cormorant breeding failures caused by PCBs ...

Point radiographic source characterization
Journal of Applied Physics, 1987A study was undertaken to find the optimal conditions for generating x rays using a high-power frequency-doubled Nd laser pulse for x-ray backlighting application. More than 30 laser shots on the Lawrence Livermore National Laboratory JANUS Research Laser system have been studied.

2. Point-source/point-receiver methods
2001Publisher Summary This chapter explains a suite of techniques that elicit information on the elastic properties of solids using point-like excitation and detection of ultrasound. These point-source/point-receiver (PS/PR) techniques have shown great promise in several materials' inspection and characterization applications.

Point Pollution Sources Dimensioning [PDF]
ECONOMIA seria MANAGEMENT / ECONOMY - MANAGEMENT series, 2011 In this paper a method for determining the main physical characteristics of the point pollution sources is presented. It can be used to find the main physical characteristics of them. The main physical characteristics of these sources are top inside source diameter and physical height.

Monopole Line Source or Point Source
2012The sound pressure free-fields of a monochromatic line or point source with a time factor \( {{\text{e}}^{{ + {\rm{j}}\omega t}}} \); \( {\text{j}} = \sqrt {{ - 1}} \); have the forms: $$ {p_{{_{\rm{Q}}}}}(r,\vartheta ) = {P_{{_{\rm{Q}}}}}\cdot \left\{ \begin{array}{clclcl} {\text{H}}_0^{{(2)}}({k_0}r)\quad {\text{line source}} \hfill \\h_0^{{(2)}}({
