Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...

introduction: the use of panoramic radiography has shown a remarkable expansion over the past 20 years. accurate positioning and preparation of patients is needed to avoid image distortion. the aim of this study was to evaluate the common errors on panoramic radiographs taken in the radiology department of rasht dental school. materials and methods: the study sample included 390 digital panoram...

This paper introduced a Particle Swarm Optimization-Radial Basis Function Neural Networks (PSO-RBFNN)-based system for heart disease detection that used the PSO algorithm to optimize RBFNN parameters. The newly developed signal digital presents results of new image contrast enhancement approach using Double Density Discrete Wavelet transform DDDWT extraction features, adaptive elimination noise...

A radix-based digital self-calibration technique for multistage analog-to-digital converter(ADC) is presented. This technique can correct errors due to capacitor mismatch and finite opamp gain. The equivalent radix of each stage is extracted by measuring the discontinuity on the ADC transfer curve and iteratively adjusting the equivalent radix to minimize this discontinuity. A much more accurat...

Color-filter-array demosaicking is an essential step in rendering full color images from single-sensor digital cameras. Because each pixel only records one color value, estimates of the missing color information at each pixel must be made. In this paper, extrapolation equations based on higher orders of the Taylor series are proposed for accurate, direction-oriented estimations of missing color...
