After many years of intensive investigation and mapping of the topography, a large number of topographic maps were produced by national mapping agencies. The explosive growth and wide availability of topographic data has created a data-rich environment for a variety of GIS users. How to make the best use of such topographic data has become a basic but daunting task. The research challenge now i...

Development of anticancer drugs targeting Aurora B, an important member of the serine/threonine kinases family, has been extensively focused on in recent years. In this work, by applying an integrated computational method, including comparative molecular field analysis (CoMFA), comparative molecular similarity indices analysis (CoMSIA), homology modeling and molecular docking, we investigated t...

The anti-oxidant activities for a diverse set of flavonoids as TEAC (Trolox equivalent anti-oxidant capacity), assay were subjected to 3D-QSAR (3 dimensional quantitative structural-activity relationship) studies using CoMFA (comparative molecular field analysis) and CoMSIA (comparative molecular similarity indices analysis). The obtained results indicated superiority of CoMSIA model over CoMFA...

We propose a high-speed contour detector for color images that produces its contours as set of edge segments, each a chain of pixels. The proposed algorithm performs a multi-scale analysis of the input image by combining the edge segments produced by Color Edge Drawing (CED) at different scales; thus, the name CEDContours. We evaluate the performance of CEDContours both qualitatively by present...

MapAnalyst is a new software application for the visualization and study of the planimetric accuracy of old maps. It illustrates local map distortion by generating distortion grids, displacement vectors, and new isolines of scale and rotation. MapAnalyst additionally computes the old map’s scale and rotation, as well as statistical indicators summarizing the map’s geometric accuracy. It offers ...
