Abstract Challenges in border security may be resolved through a team of autonomous mobile robots configured as a flexible sensor array. The robots will have a prearranged formation along a section of a border, and each robot will attempt to maintain a uniform distance with its nearest neighbors. The robots will carry sensor packages which can detect a signature that is representative of a huma...

the study area locates between an active fault system of north anatolian in turkey and active alborz and zagros mountain ranges in iran. the total shortening concluded from arabia-eurasia collision with a rate of 22 mm/year across the ne persia is partitioned  into  two  fault  systems,  right-lateral  strike slip  movements  in  the  turkish-iranian  plateau  like  north tabriz fault system an...

This work proposes a genetic algorithm based technique to learn the structural description of the circuit under study, in order to give it an on line fault tolerant cover. As the circuit operates, its input / output sequences are used to learn the structural configuration of the hardware. Once the structure is evolved, the algorithm redistributes the available redundancy and generates multiple ...

Metal-dielectric multilayered metamaterials are proposed to work as wideband spectral-selective emitters/absorbers due to the topological change in isofrequency contour around the epsilon-near-zero point. By setting the transition at the border between the visible and IR ranges, the metal-dielectric multilayered metamaterials become good absorbers/emitters for visible light and good reflectors ...

-The internal properties within and adjacent to fault zones are reviewed, principally on the basis of laboratory, borehole, and seismic refraction and reflection data. The deformation of rocks by faulting ranges from intragrain microcracking to severe alteration. Saturated microcracked and mildly fractured rocks do not exhibit a significant reduction in velocity, but, from borehole measurements...

The geomorphology and structural geology ofNemegt Uul, Southern Mongolia, is examined as an example of a mountain range that has formed within a restraining bend along a major intracontinental strike-slip fault system, the Gobi-Tien Shan fault system. Structural and geomorphological analysis demonstrates that the mountain belt is young and has been differentially tilted and eroded. A geomorphol...

Response analysis of the buried pipeline subjected to reverse fault displacement is very important for design, detection and protection of buried pipelines. This paper looks at the buckling behavior of a buried pipeline subjected to reverse fault displacement in the rock stratum. Effects of internal pressure, wall thickness, fault displacement and burial depth on the buckling mode and the axial...

We estimated the energy radiated by earthquakes in southern California using on-scale very broadband recordings from TERRAscope. The method we used involves time integration of the squared ground-motion velocity and empirical determination of the distance attenuation function and the station corrections. The time integral is typically taken over a duration of 2 min after the P-wave arrival. The...

In this paper, the results of an experimental study on the error sensitivities of application data are presented. We develop a portable software-implemented fault-injection (SWIFI) tool that, on top of performing single-bit flip fault injections and capturing their effects on application behavior, is also data-level aware and tracks the corrupted application data to report their high-level char...

Geological structures such as faults play a critical role in the flow of fluids reservoir by affecting its permeability. This study explores Chaman Fault distribution hydrological division, groundwater separation aquifer systems Khojak and basins. The is left-lateral strike-slip transform plate boundary located at border city Chaman, District Killa Abdullah, Balochistan. fault plays an importan...
