Inferences on the source mechanisms of the 1930 Irpinia (Southern Italy) earthquake from simulations of the kinematic rupture process
1930 Irpinia earthquake ground motion simulation kinematic source model
2015/9/11
We examine here a number of parameters that define the source of the earthquake that occurred on 23rd July 1930 in Southern Italy (in the Irpinia region). Starting from the source models proposed in d...
Kinematic GPS survey as validation of LIDAR strips accuracy
LIDAR GPS DTM landslide body Sarno
2015/9/7
As a result of the catastrophic hydrogeological events which occurred in May 1998 in Campania, in the south of Italy, the distinctive features of airborne laser scanning mounted on a helicopter were u...
Implicit numerical integration of a three-invariant, isotropic/kinematic hardening cap plasticity model for geomaterials
Kinematic hardening Spectral decomposition Plasticity Geomechanics Implicit integration
2015/7/1
The mechanical constitutive behavior of geomaterials is quite complex, involving pressure-sensitive yielding, differences in strength in triaxial extension vs. compression, the Bauschinger effect, dep...
Nuclear Rings in Galaxies---A Kinematic Perspective
Nuclear Rings Galaxies---A Kinematic Perspective
2011/10/19
We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their resonant origin. The ...
Kinematic signature of an intermediate-mass black hole in the globular cluster NGC 6388
black hole physics – globular cluster: individual (NGC 6388) – stars: kinematics and dynamics
2011/10/12
Intermediate-mass black holes (IMBHs) are of interest in a wide range of astrophysical fields. In particular, the possibility of finding them at the centers of globular clusters has recently drawn att...
Kinematic dynamo simulations of von Kármán flows: application to the VKS experiment
von Kármán flows Kinematic dynamo simulations VKS experiment
2011/7/7
The VKS experiment has evidenced dynamo action in a highly turbulent liquid sodium von K\'arm\'an flow [R. Monchaux et al., Phys. Rev. Lett. {\bf 98}, 044502 (2007)]. However, the existence and the on...
The kinematic identification of a thick stellar disc in M31
The kinematic identification stellar disc
2011/1/11
Submitted on 25 Oct 2010 (v1), last revised 21 Dec 2010 (this version, v2))
Abstract: We present the first characterization of a thick disc component in the Andromeda galaxy (M31) using kinematic dat...
Quantifying Kinematic Substructure in the Milky Way's Stellar Halo
Cosmology stellar halo galaxies individual(Milky Way) Galaxy halo Galaxy
2010/11/12
We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for position-velocity su...
The kinematic characteristics of magnetic O-type stars
astrometry — stars early-type — stars magnetic field — stars kinematics and dynamics open clusters
2010/11/15
Although magnetic fields have been discovered in ten massive O-type stars during the last years, the origin of their magnetic fields remains unknown. Among the magnetic O-type stars, two stars, HD3687...
In this work we investigate numerically the kinematic dynamo driven by spherical Couette flow. We calculate both 2D and 3D flows, different global rotation rates, opposite directions of differential ...
The Inversion of the Real Kinematic Properties of Coronal Mass Ejections by Forward Modeling
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The kinematic properties of coronal mass ejections (CMEs) suffer from the projection effects, and it is expected that the real velocity should be larger and the real angular width should be smaller th...
Analysis of kinematic waves arising in diverging traffic flow models
Kinematic wave models diverging traffic Riemann problem supply-demand space
2010/12/13
Diverging junctions are important network bottlenecks, and a better understanding of diverging
traffic dynamics has both theoretical and practical implications. In this paper, we first
introduce a c...
On the application of kinematic models to simulate the diffusive processes of debris flows
On the application kinematic models simulate the diffusive processes debris flows
2010/10/21
Debris flows generally propagate along steep mountain torrents with dynamics primarily governed by gravitational and frictional forces. Thus, debris flows modelling can be successfully performed throu...
Kinematic Self-Similar Solutions of Locally Rotationally Symmetric Spacetimes
Locally rotationally symmetric Self-similarity
2010/6/30
This paper contains locally rotationally symmetric kinematic self-similar perfect fluid and dust solutions. We consider three families of metrics which admit kinematic self-similar vectors of the firs...
