Seismic noise emission induced by seismic waves
The in situ rock undergoing different kinds of deformation accumulates elastic energy that can be released spontaneously o r under artificial effect. Triggering of energy can also be performed by means of a dynamic excitation caused by elastic waves. W e carried out special field investigations with the use of seismic vibrators (Vibroseis-like sources) to study the effect of the energy release ...
متن کاملSensitivity of ionosonde detection of atmospheric disturbances induced by seismic Rayleigh waves at different latitudes
Ionospheric disturbance was observed in ionograms at Kazan, Russia (55.85◦N, 48.81E), associated with the M8.8 Chile earthquake in 2010 (35.91◦S, 72.73W). The disturbance was caused by infrasound waves that were launched by seismic Rayleigh waves propagating over 15,000 km along Earth’s surface from the epicenter. This distance was extremely large compared with the detection limit of similar io...
متن کاملRadiation of Surface Waves into Concrete by Means of a Wedge Transducer: Design and Optimization
Spectral Analysis of Surface Waves (SASW) has been used for two decades to determine the stiffness profile of soils. The application of this technique is currently evaluated for inspecting subsurface damage in concrete structures in the 100 kHz frequency range. Accurate measurements of phase velocity and attenuation require an appropriate source to efficiently generate wideband Rayleigh waves. ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولDeterministic Deconvolution of Ground‐Penetrating‐Radar Data at a Limestone Quarry
A 30 m by 30 m two-dimensional grid was designed on a flat bench behind a quarry face of predominantly limestone with thin shale layers located at a Bonner Springs, Kansas site to test the utility of ground-penetrating radar (GPR) for stratigraphic studies. GPR data were collected along seven lines parallel to the quarry face and seven lines perpendicular to the quarry face, each separated by 5...
