111Fat Man — This article is about the World War II nuclear weapon. For other uses, see Fat Man (disambiguation). Fat Man (Atomic Bomb) Mockup of the original weapon …
112Plane wave — [ real part of a plane wave travelling up.] In the physics of wave propagation (especially electromagnetic waves), a plane wave (also spelled planewave) is a constant frequency wave whose wavefronts (surfaces of constant phase) are infinite… …
113Speckle imaging — (also known as video astronomy ) describes a range of high resolution astronomical imaging techniques based either on the shift and add ( image stacking ) method or on speckle interferometry methods. These techniques can dramatically increase the …
114Regulation of gene expression — Gene modulation redirects here. For information on therapeutic regulation of gene expression, see therapeutic gene modulation. For vocabulary, see Glossary of gene expression terms Diagram showing at which stages in the DNA mRNA protein pathway… …
115Load-balanced switch — A load balanced switch is a switch architecture which guarantees 100% throughput, (the equivalent of perfect arbitration), with no central arbitration at all, at the cost of sending each packet across the crossbar twice. Load balanced switches… …
116Polygonal modeling — In 3D computer graphics, polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygons. Polygonal modeling is well suited to scanline rendering and is therefore the method of choice for real …
117Fresnel diffraction — In optics, the Fresnel diffraction equation for near field diffraction, is an approximation of Kirchhoff Fresnel diffraction that can be applied to the propagation of waves in the near field.[1] The near field can be specified by the Fresnel… …
118David L. Fried — is a scientist, best known for his contributions to optics. Fried described what has come to be known as Fried s seeing diameter, or r0 (usually pronounced r naught). The seeing diameter is effectively a limiting aperture due to atmospheric… …
119Seismic Handler — (SH) is an interactive analysis program for preferably continuous waveform data. It was developed at the Seismological Observatory Gräfenberg and is in use there for daily routine analysis of local and global seismic events. In original form… …
120Optical lens design — refers to the calculation of lens construction parameters (variables) that will meet a set of performance requirements and constraints, including cost and schedule limitations. Construction parameters include surface profile types (spherical,… …
