Both seismological and geodynamic research emphasize that the Aegean Region, which comprises the Hellenic Arc, the Greek mainland and Western Turkey is the most seismically active region in Western Eurasia. The convergence of the Eurasian and African lithospheric plates forces a westward motion on the Anatolian plate relative to the Eurasian one. Western Anatolia is a valuable laboratory for Ea...

We present a method of proving existence of center manifolds within specified domains. The method is based on a combination of topological tools, normal forms, and rigorous computer-assisted computations. We apply our method to obtain a proof of a center manifold in an explicit region around the equilibrium point L1 in the Earth–Sun planar restricted circular three-body problem.

A magnesium alloy with lean additions of Zn (1 wt.%) and Ca (0.3 wt.%), ZX10, pure Mg were subjected to orientation-dependent micropillar indentation tests at ambient temperature. Single-crystalline micropillars two different orientations fabricated activate extension compression along the c-axis, respectively. For both loading conditions, ZX10 exhibits a strengthening increment by factor 2 2.5...

Abstract We assess how recent glacial isostatic adjustment (GIA) and inter‐earthquake stress transfer modulated the state of on major faults in Southeast Alaska, these effects may have influenced large moderate earthquakes. The Glacier Bay Icefield has lost >3,000 km 3 ice since ca. 1770, with thinning up to 1.5 km, rest southeast Alaska been deglaciating 1900. resulting GIA response solid e...

This paper explores the problem of attitude stabilization spacecraft under multiple uncertainties and constrained bandwidth resources. The proposed control law is designed by combining sliding mode (SMC) technique with a prescribed performance (PPC) method. Further, input signal executed in an aperiodic time framework using event-trigger (ET) mechanism to minimize data transfer through wireless...

A particular periodic orbit in the Earth-Sun circular restricted three body problem is shown to have the characteristics needed for a ballistic lunar capture transfer. An injection from a circular parking orbit into the periodic orbit serves as an initial guess for a targeting algorithm. By targeting appropriate parameters incrementally in increasingly complicated force models and using precise...

This paper investigates displaced periodic orbits at linear order in the circular restricted Earth-Moon system (CRTBP), where the third massless body utilizes a hybrid of solar sail and a solar electric propulsion (SEP). A feedback linearization control scheme is implemented to perform stabilization and trajectory tracking for the nonlinear system. Attention is now directed to binary asteroid s...
