We investigated mass balance changes over five ice rises in the last few decades near Fimbul and Nivl shelves central Dronning Maud Land. use Input-Output Method constrained using field-based geophysical measurements conducted during austral summers of 2012–14 three Ice Shelf. Further, we satellite altimetry data (ICESat, ICESat-2, CryoSat-2) to estimate geodetic all recent decades. Both field-...

the zagros fold-and-thrust belt is tectonically active and often has active faults with insensible and slow motions. determining the rate of movement and displacement in these faults requires very precise measurements. one of the measurement methods of fault movements is using geodetic and micro-geodetic studies. this research is focused on one of the active faults in the north of shiraz city, ...

In 1960, Theodore H. Maiman, of the Hughes Aircraft Company, successfully operated the first device to generate an intense beam of highly coherent monochromatic radiation. He called his device a laser for light amplification by the stimulated emission of radiation. The laser has become ubiquitous, with literally hundreds of uses ranging from optical surgery to precision machining. Lecturers use...

The geodetic and frame-dragging effects are the direct consequences of spacetime curvature near Earth which can be probed from Gravity probe B (GP-B) satellite. satellite result matches quite well with Einstein's general relativistic result. gyroscope measures contains lots electrons nucleons. Ultralight axions, vector gauge bosons, unparticles interact these nucleons through different spin-dep...

Permafrost-affected soils cover about 40–45 % of Canada. The environment in such areas, especially those located within the discontinuous permafrost zone, has been impacted more than any other by recorded climatic changes. A number of changes, such as surface subsidence and the degradation of frost mounds due to permafrost thawing, have already been observed at many locations. We surveyed three...

In the integration of geodetic networks with different geodetic coordinate systems, the similarity transformation seems to be the most suitable method because the geodetic coordinate systems are designated to be Cartesian (orthogonal). However, this method may always not be practical to use in most surveying works demanding such high accuracies as the coordinates used in the transformation are ...

Let G : (V, E, ω) 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 ω: E    . A u−v path P in G 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...

For a connected graph G of order n, a set S of vertices is called a double geodetic set of G if for each pair of vertices x, y in G there exist vertices u, v ∈ S such that x, y ∈ I[u, v]. The double geodetic number dg(G) is the minimum cardinality of a double geodetic set. Any double godetic of cardinality dg(G) is called dg-set of G. The double geodetic numbers of certain standard graphs are o...

[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...
