expensive to provide these maps  with field measurements  therefore  it is better to use new methods. this study provides a lithological and alteration mapping units with dominant minerals based on hyperspectral images of eo1-hyperion satellite. to do so, two different zones  were  investigated:  the  cuprite-nevada  and  mozahem  volcano  in  iran  which  have suitable conditions for our study...

This paper presents a survey on soil Pb concentration around Sepahanshahr town located in vicinity of Isfahan. Due to the lack of regulation and environmental education and awareness, Sepahanshahr is now a rapid growing residential area suffering from the considerable consequences of poorly regulated mining activities operating in its vicinity. The aim of this study is to explore the spatial st...

Introduction: Enough scientific evidence is available on the harmful effects of air pollution health human beings, fauna, flora, and ecosystems in general. The mechanical electronical monitoring networks are first option for quality diagnosis, but they do not allow a direct precise assessment impacts living organisms that may result from exposure to pollutants. Objective: To evaluate changes co...

Oil extraction and transportation may lead to small or large scale accidental spills, whether at sea on land. Detecting these spills is a major problem that can be addressed by means of hyperspectral images specific processing methods. In this work, several cases onshore oil are studied. First, controlled experiment was carried out: four boxes containing soil sand mixed with crude gasoil were d...

we prove a strong convergence result for a sequence generated by halpern's type iteration for approximating a common fixed point of a countable family of quasi-lipschitzian mappings in a real hilbert space. consequently, we apply our results to the problem of finding a common fixed point of asymptotically nonexpansive mappings, an equilibrium problem, and a variational inequality problem for co...

Buffer caches in operating systems keep active file blocks in memory to reduce disk accesses. Related studies have focused on minimizing buffer misses and the resulting performance degradation. However, the side effects and performance implications of accessing the data in buffer caches (i.e. buffer cache hits) have been ignored. In this paper, we show that accessing buffer caches can cause ser...
