This abstract describes the segmentation system used to participate in the challenge ISIC 2017: Skin Lesion Analysis Towards Melanoma Detection. Several preprocessing techniques have been tested for three color representations (RGB, YCbCr and HSV) of 392 images. Results have been used to choose the better preprocessing for each channel. In each case a neural network is trained to predict the Ja...

in order to transfer rhizomania resistance genes to improved sugar beet lines, crosses were made between 11 commercial resistant varieties and two improved inbred o-type lines of sugar beet (231 and 261) at agricultural research center of khorasan razavi   and jam sugar factory in 2007. o-types carried self fertile (sf) genes and contained male sterile (ms) genotypes. commercial varieties were ...

Geometallurgy tries to predict the instability the behavior of ores caused by variability in the geological settings, and to optimize the mineral value chain. Understanding the ore variability and subsequently the process response are considered to be the most important functions of an accurate geometallurgical study. In this paper, the geometallurgical index is presented as a new tool to...

A connected pseudocomplete n-coloring of a graph G is a (non-proper) n-coloring of the vertices of G such that each color class induces a connected subgraph and for each pair of color classes there is an edge with one end of each color; this can be viewed as a kind of “inverse image” of a clique minor. The connected pseudoachromatic index of a graph G is the largest n for which the line graph o...
