FORMING OF THE MODEL SIGNAL IN DEVICE USED TO RECOGNITION OF GROUND MOVING OBJECTS
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019 For detection and recognition of ground moving objects with seismic devices it's nesessary to form the model of seismic signals, corresponding of each object class.

3D velocity-depth model building using surface seismic and well data [PDF]
, 1998 The objective of this work was to develop techniques that could be used to rapidly build a three-dimensional velocity-depth model of the subsurface, using the widest possible variety of data available from conventional seismic processing and allowing for

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Directionality Scaling of Scalar and Vector Ground Motion Intensity Measures
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The azimuthal directionality of earthquake ground‐motion intensity measures (IMs) is conventionally described by the ratios between the orientation‐independent maximum (RotD100) and median (RotD50) values over the horizontal plane. This study presents a refined characterization of the directionality of 31 IMs, including spectral accelerations (

IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSeismic random noise attenuation is an essential step in seismic data processing. Noise in seismic data may degrade their quality, which leads to misinterpretation of Earth's subsurface structures.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Seismic anisotropy in siliciclastic reservoir rocks [PDF]
, 2006 The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements
