The advantages of small incision cataract surgery may be obtained without relying on expensive and complicated instrumentation. A new technique which manually splits the nucleus and removes the fragments is described.
A wavenumber filter can be used in conjunction with the Hartley‐Tuller‐Shannon formula to bring about some reduction in the number of ambiguous contours on a gravity map. The filter focuses the interpreter’s attention on the maximum response to density changes within a given layer. At the same time, characteristics of the filter design, such as bandwidth and power of the desired output relative to other interfering outputs, can be used in the H‐T‐S formula to determine a minimum contouring threshold, such that the relative number of false anomalies and missed true anomalies is minimized. In addition, it is also possible to estimate a lower limit on the probability that an anomaly observed on a map originates in a target layer.
The complex analytic signal. A modulated carrier f(t), its quadrature function F (t), and the associated complex analytic signal are ayl shown as functions of the real variable time (after Bracewell, 1965
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
