Detecting variation in the evolutionary process along chromosomes is increasingly important as whole-genome data become more widely available. For example, factors such as incomplete lineage sorting, horizontal gene transfer, and chromosomal inversion are expected to result in changes in the underlying gene trees along a chromosome, while changes in selective pressure and mutational rates for d...

todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. in this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. most algorithms presented in the context of data stream mining and frequent pattern detection, work either on uncertai...

This paper presents novel image contrast enhancement models using Xilinx System Generator (XSG). The proposed models are specifically to enhance the images captured under extremely dark / non-uniform lighting environment as well as for poor contrast environment. To perform the contrast enhancement the proposed design adapts windowing operation by utilizing linear intensity scaling and clipping....

A clear sky, daytime retrieval of low-level precipitable water vapor based on the single-layer approximation to radiative transfer equation applied three longwave window channels is described. The algorithm, which simultaneously retrieves skin temperature and air as well, has advantage using satellite radiances only—no ancillary information needed. Application method Geostationary Operational E...
