intensity pattern
121Antenna gain — is defined as the ratio of the radiation intensity of an antenna in a given direction, to the intensity of the same antenna as it radiates in all directions (isotropically). Since the radiation intensity of an isotropically radiated power is… …
122Monsoon — This article is about the seasonal winds. For other uses, see Monsoon (disambiguation). Part of the Nature series on …
123Holography — (from the Greek, ὅλος hólos whole + γραφή grafē writing, drawing) is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the… …
124Prostate cancer — is a disease in which cancer develops in the prostate, a gland in the male reproductive system. It occurs when cells of the prostate mutate and begin to multiply out of control. These cells may spread (metastasize) from the prostate to other… …
125Fraunhofer diffraction — In optics, Fraunhofer diffraction is a form of wave diffraction, which occurs when field waves are passed through an aperture or slit, causing only the size of an observed aperture image to change Hecht, E. (1987) , p396 Definition of Fraunhofer… …

127Structure factor — In physics, in the area of crystallography, the structure factor of a crystal is a mathematical description of how the crystal scatters incident radiation. The structure factor is a particularly useful tool in the interpretation of interference… …
128Scale-space segmentation — or multi scale segmentation is a general framework for signal and image segmentation, based on the computation of image descriptors at multiple scales of smoothing. One dimensional hierarchical signal segmentationWitkin s seminal work in scale… …
