required. These basic properties of the soil can then be evaluated to assess the acoustic imaging tradeoffs for The potential application of this work is the detection and imaging detecting and characterizing buried artifacts. The acousof buried objects using acoustic methodology. To image buried artifacts, it is vital to know speed and attenuation of sound in the particular tic attenuation coe...

Refractor ambiguities are big problem in seismic refraction method especially in seismic engineering. There can be hidden subsurface geological phenomena such as hidden faults and shear zones which are not simply predicted by the travel-time graph or some geophysical methods. Head wave amplitudes are used to show the resolution of refractor ambiguities and the existence of anisotropy in complex...

This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...

background: both increased arterial stiffness and hyperuricaemia are associated with elevated cardiovascular risks. little is known about the relations of serum uric acid (ua) level to regional arterial stiffness and wave reflection. the aim of the study was to investigate the gender-specific association of serum ua and indices of arterial function in a community-based investigation in china. m...

We applied active-source seismic method for the interpretation of elastic parameters in tailings facilities which is essential evaluating stability and response. The methodology uses different analysis methods on same dataset, i.e., conventional refraction (SR) to determine compressional-wave velocity (Vp) multichannel surface wave (MASW) estimate shear-wave (Vs). Seismic velocities conjunction...

High-frequency geometric ray theory i8 used to investigate the refracted arrival from a high-speed layer embedded in an infinite medium. The effect of changing the layer thickness to dominant wavelength ratio (E/ ^ ) and the range io depth ratio ( p/H) is analyzed for a point oempressional source. The results approximate the exact solution when E/Väsf . The theory predicts shingling and shows t...

The elasticity of high-pressure mantle phases may be characterized by crystal chemically similar compounds. Analogue compounds available as single crystals yield the most reliable elastic constant data. The single-crystal elastic constants of pleonaste and hercynite spinel, rutile-structure germanium dioxide, and spessartite-almandine garnet are studied, in most cases as a function of pressure ...

Whole-core measurements of Wet Bulk Density (WBD), compressional (P)-wave velocity (Vp), and Magnetic Susceptibility were measured at a sampling interval of 1 or 2 centimetres (cm) throughout the AND-2A drill core for initial core characterisation and on-site correlation with seismic modeling to predict target-reflector depth. Measurements were made using a GEOTEK (Multi-Sensor-Core-Logger MSCL...
