The estimation of soil parameters of multilayer structure leads to useful information for designing a safe grounding system. This paper presents a nonlinear regression based estimation scheme to extract soil parameters from the kernel function of apparent earth resistivity. The kernel function of apparent earth resistivity can be obtained from the measured apparent earth resistivity data. The p...

Earth dam is a structure as homogeneous or non-homogeneous forms for raising water level or water supply. Earth dam consist of different parts that one of the main parts is clay core. Choosing an optimal non permeable core which causes reduction of seepage through dam body and also being stable is necessary. The objective of this research is to optimize the geometry of earth dam clay core such ...

The planned Ares V launch vehicle with its 10 meter fairing shroud and 55,000 kg capacity to the Sun Earth L2 point enables entirely new classes of space telescopes. NASA MSFC has conducted a preliminary study that demonstrates the feasibility of launching a 6 to 8 meter class monolithic primary mirror telescope to Sun-Earth L2 using an Ares V. Specific technical areas studied included optical ...

We use high-resolution angle-resolved photoemission spectroscopy (ARPES) and electronic structure calculations to study the electronic properties of rare-earth monoantimonides RSb (R = Y, Ce, Gd, Dy, Ho, Tm, Lu). The experimentally measured Fermi surface (FS) of RSb consists of at least two concentric hole pockets at the Γ point and two intersecting electron pockets at the X point. These data a...

Strong seasonal variations of horizontal and vertical positions are observed on GPS times series from stations located in Nepal, India and Tibet (China). We demonstrate that this geodetic deformation is induced by seasonal variations of continental water storage driven by the Monsoon. For this purpose, we use satellite data from the Gravity Recovery and Climate Experiment (GRACE) to determine t...

Development of high fidelity earth system models is important to the understanding of earth system science. Along with several decades of active developments, the complexity of the model’s software structure became a barrier that hinders model interpretation and further improvements. In this paper, a web-based visual analytic system is introduced to better understand the software structure of C...
