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...

Accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.Acoustic method can be used as analternative and effective tool for permeability determination. In this study, a four-step approach is proposed for permeability estimati...

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...

{ 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...
