Abstract Laboratory experiments with seismic measurements have the potential to be highly useful for understanding physical process of water-induced landslides, and fundamental are helpful appropriate interpretation recorded seismograms. We developed a laboratory measurement system investigate relationships between wave propagation water saturation in sand. considered that wavelength should com...

Nufferno Speed Test In this investigation we have used only the Nufferno speed test, which is designed to measure speed as distinct from general level of intelligence. It consists of 19 problems of the Thurstone letterseries type in each of which the patient is presented with series of letters and is required to add at the end of the series the letter which is appropriate to the sequence (Furne...

The linearized wave-equation MVA operator can be used for velocity analysis using both Born and Rytov approximations. The distinction arises from the method used to compute the image perturbations. Both approximations suffer from limitations that limit their practicality: the Born approximation is usable only for small anomalies, while the Rytov approximation requires phase unwrapping. Differen...

{ Methods are developed for design of linear tomographic reconstruction algorithms with speciied properties. Assuming a starting model with constant slowness, an algorithm with the following properties is found: (1) The optimum constant for the starting model is determined automatically. (2) The weighted least-squares error between the predicted and measured traveltime data is as small as possi...

Works conducted in logistics management mostly emphasize the importance of a ‘time compression’ strategy to develop a sustainable competitive advantage. At the level of the design, manufacturing or distribution of products to consumers, high-speed orientation is now considered to be a universal source of performance. Drawing from current developments in the French food retailing industry, the p...

The seismic arrays of the International Monitoring System (IMS) for the Comprehensive Nuclear-Test-Ban Treaty (CTBT) are highly diverse in size and configuration, with apertures ranging from under 1 km to over 60 km. Large and medium aperture arrays with large inter-site spacings complicate the detection and estimation of high-frequency phases lacking coherence between sensors. Pipeline detecti...
