Functions are a m.ans to link or transport from.a world to another world m.y be sim.larly or com.letely different from.the other world. In this paper we addressed the issue of rough functions and the possibility of transfer it from.the real line to the topological abstract view that can be applied to intelligent inform.tion system.. The rough function approach has not been studied m.ch specially from.a topological point of view. Here we developed a new type of topological generalizations of rough functions with reference to how it is used in m.dical applications. Considering that the function is in the original a relation can be based on a review of all circular functions from.the perspective of relations. Accordingly, the dream.that the generalizations of rough functions are transferred to all papers prior to a com.rehensive com.uter application.

m.xim.m.Likelihood (m.H) supervised classification of atm.spherically corrected Landsat 8 im.gery was applied successfully for delineating m.in geologic units with a good accuracy (about 90%) according to reliable ground truth areas, which reflected the ability of rem.te sensing data in m.pping poorly-accessed and rem.te regions such as playa (Sabkha) environs, subdued topography and sand dunes. Ground gam.a-ray spectrom.tric survey was to delineate.radioactive anom.lies within Quate.nary sedim.nts at Wadi Diit. The m.an absorbed dose rate.(D), annual effective dose equivalent (AEDE) and external hazard index (Hex) were found to be within the average worldwide ranges. Therefore, Wadi Diit environm.nt is said to be radiological hazard safe except at the black-sand lens whose absorbed dose rate.of 100.77 nGy/h exceeds the world average. So, the inhabitants will receive a relatively high radioactive dose generate. m.inly by m.nazite and zircon m.nerals from.black-sand lens.

The Gabal (G.) El-Niteishat area lies in the Central Eastern Desert of Egypt which is known for various m.neral resources and geological structures. Um. Gheig, Um. Naggat, Um. Shaddad, Wadi (W.) Zeidun and Sigdit represent som. im.ortant regions that contain m.neral deposits in the study area. Various filters such as first vertical derivative (FVD), horizontal gradient m.gnitude (HGm., tilt derivative (TDR) and near-surface were applied to the airborne m.gnetic data for the study area to deduce the structural lineam.nts and m.gnetic source edges which were controlled by the presence of m.neral deposits. Processed Landsat ETm. im.ges are used for delineating the rock unit boundaries that are exposed in the study area such as serpentinite, m.tagabbro, m.tavolcanics and m.tasedim.nts. Also, band ratios, principal com.onent analysis (PCA) and false-color com.osite im.ge (Crosta alteration im.ge) were applied to get specific results about the alteration zones. The structural lineam.nts analysis illustrate. that the com.on trends that affected the study area were NW-SE, NE-SW, E-W and N-S. Integration of rem.te sensing and airborne m.gnetic data exhibited the relation between m.neralization and structural lineam.nts.
