The solid Earth strains in response to the gravitational pull from the Moon, Sun, and other planetary bodies.Measuring the flexure of geologic material in response to these Earth tides provides information about the geomechanical properties of rock and sediment.Such measurements are particularly useful for understanding dilation of faults and fract
Mobile robot path planning with reformative bat algorithm.
Mobile robot path planning has attracted much attention as a key technology in robotics research.In this paper, a reformative bat algorithm (RBA) for mobile robot path planning is proposed, which is employed as the control mechanism of robots.The Doppler effect is applied to frequency update to ameliorate RBA.When the robot is in motion, the Dopple
Photonic Topological States in a Two-Dimensional Gyrotropic Photonic Crystal
Time-reversal symmetry (TRS) of electrons is associated with an anti-unitary operator with T 2 = − 1 , which induces Kramers degeneracy and plays an important role in realizing the quantum spin Hall effect (QSHE).By contrast, TRS of photons is described by T b 2 = 1.We point out that due to this difference, TRS is not the necessary condition
Subduction, collision and plumes in the epoch of the Late Paleozoic magmatism of the Magnitogorsk zone (the Southern Urals)
Subject.A systematization of Late-Paleozoic magmatic formations of the Magnitogorsk zone of the Southern Urals in the process of an accretion of the Magnitogorsk paleoarc to the margin of the East European continent (EEC) with formation in Famenian and Carboniferous active continent margin of South-Uralian accretionary-collisional belt was given in
