The Benínar Dam, located in Southeastern Spain, is an earth-fill dam that has experienced filtration issues since its construction 1985. Despite the installation of various monitoring systems, data collected are sparse and inadequate for dam’s lifetime. present research integrates Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) modeling to validate this dam, opening way enhan...

The paper discusses the issue of safe functioning of large technical systems (LTS) and questions what are the principles of “operating and living together” of heterogeneous communities. It argues that personal interactions between humans, nature, and technology are crucial for the sustainable operation of socio-technical systems. The paper presents some results of an “ethnographic case study” c...

The Heterogeneous EARtH algorithm aim at finding the optimal platform energy point of a heterogeneous cores CPU by selecting the right core and changing the voltage and frequency of operation. The algorithm is based on a theoretical model employing a small number of parameters, which are extracted from real systems using off-line and run-time methods. The model and algorithm have been validated...

the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...

The parameters of the constitutive model, the creep model, and the wetting model of materials of the Nuozhadu high earth-rockfill dam were back-analyzed together based on field monitoring displacement data by employing an intelligent back-analysis method. In this method, an artificial neural network is used as a substitute for time-consuming finite element analysis, and an evolutionary algorith...

30 Abstract—The blessings of hyperspectral remote sensing are manifold and it has enabled researchers to locate, map and identify different materials on the surface of Earth. Hyperspectral remote sensing play a key role in mineral mapping activities and it can be a much powerful and cost effective tool for mineral development activities in a developing country like Pakistan where there are rich...

Advances in data collection and data storage technologies have made it possible to acquire massive Earth science data sets. In principle, these data sets could be transformed into great scientific discoveries. However, due to the heterogeneous nature and to the scale of the available Earth science data, traditional analysis methods are challenged and much of these data remain largely unexplored...

This paper introduces an accurate, fast, and applicable method for optimization of slip surfaces in earth slopes. Using Genetic Algorithm (GA), which is one of the modern and non-classic optimization methods, in conjunction with the well -known Bishop applied method, the optimum slip surface in an earth slope is investigated and its corresponding lowest safety factor is determined. Investigati...

Four multitopic Schiff-base ligand precursors were synthesized via condensation of 4,4'-diol-3,3'-diformyl-1,1'-diphenyl or 1,3,5-tris(4-hydroxy-5-formylphenyl)benzene with 2,6-diisopropylaniline or 2,6-dimethylaniline. Amine elimination reactions of Ln[N(SiMe(3))(2)](3) (Ln = La, Nd, Sm or Y) with these multitopic ligand precursors gave ten heterogeneous rare-earth metal catalysts. These heter...
