[1] The geodetic velocity and strain rate patterns in Anatolia constrain the rheology of the lithosphere, once compared with thin shell finite element tectonic model predictions. Geodetic and modeled deformation favors a hard lithospheric rheology, responsible for the high EastWest horizontal velocities in the center of Anatolia, between 39 –41 N, in proximity of the North Anatolian Fault. The ...

Let tt : (V, E, W ) be a finite, connected, weighted graph without loops and multiple edges. In a weighted graph each arc is assigned a weight by the weight function W : E +. A u v path P in tt is called a weighted u v geodesic if the weighted distance between u and v is calculated along P . The strength of a path is the minimum weight of its arcs, and length of a path is the number of edges in...

Several hundreds of compact extragalactic radiosources (mainly quasars, but also BL Lac and galaxies) are monitored in a series of permanent VLBI geodetic and astrometric programs that were initiated in the late 1970’s in support to the solar system exploration, for studying the Earth’s rotation and crustal deformations, and for creating the celestial reference frame later recommended by the IA...

This paper presents a methodology for planimetric adjustment of elevation data to the SRTM Digital Elevation Model (SRTMDEM), by correlation. It can be applied to geo-reference any geographic dataset with an elevation component, such as rasterised maps with contours or DEMs. The accuracy around 5 meters was achieved by this geo-referencing method assessed using elevation data from Portugal deri...

This is a non-linear diffusion equation, and the coefficients āi j, c̄ depend on the solution f . Here we are mainly concerned with the Gevrey class regularity for the solution of the Landau equation. This equation is obtained as a limit of the Boltzmann equation when the collisions become grazing (see [8] and references therein). Recently, a lot of progress has been made on the study of the Sob...

A geometry in Oracle Spatial can be one of the following1: • Point • Linestring connecting two or more points • Polygon specified as a closed linestring and indicating an area bounded by the linestring (with zero or more holes inside the outer bounding linestring) • Multipoint collection • Multiline collection consisting of unconnected linestrings • Multipolygon collection consisting of nonover...

Buckley and Harary introduced several graphical invariants related to convexity theory, such as the geodetic number of a graph. These invariants have been the subject of much study and their determination has been shown to be NP -hard. We use the probabilistic method developed by Erdös to determine the asymptotic behavior of the geodetic number of random graphs with fixed edge probability. As a...

Geodetic positioning is the geophysical record of reference for slow slip events, but typical daily solutions limit studies evolution to its long-term dynamics. Accompanying seismic low-frequency earthquakes located precisely in time and space provide an opportunity image dynamics at subdaily scales. Here we show that a high-resolution history earthquake fault alone can reproduce geodetic obser...
