5D interpolation followed by azimuthal prestack migration results in better conditioned gathers for Amplitude Versus Offset (AVO) and Amplitude Versus Azimuth (AVAz) analysis. The data should be prestack migrated prior to AVO or AVAz analysis, but this often proves problematic for land data due to the poor sampling of the data in offset and azimuth. This sparse sampling results in incomplete co...

Data-driven dashboards have now become ubiquitous. Environments such as information kiosks in public spaces, dashboards in cars, or smart televisions at home – all cater to a casual form of data exploration, where the user may have a quick-and-simple information need. In contrast to long and complex database query sessions for experts, casual queries pose two requirements to the query interface...

This study presents relevant characteristics of library automation systems and digital library systems that need to be taken into account in addressing the study of log data in digital libraries. For all the different categories of users of a digital library system, the quality of services and documents the digital library supplies are very important. Log data constitute a relevant aspect in th...

an improved model of mud dispersion has been introduced in this work. the advantages of this model consist of a new analytical correlation for dispersivity by using resistivity log data and using a new aspect of capacitance dispersion model. mathematical formulations were expressed, solved by numerical model taking advantage of actual log and formation data. achieved results yielded reasonable ...

In this review I show that four major kinds of theoretical approaches have been used to explain the scaling of metabolic rate in cells, organisms and groups of organisms in relation to system size. They include models focusing on surface-area related fluxes of resources and wastes (including heat), internal resource transport, system composition, and various processes affecting resource demand,...

An optimal O(loglogn) time concurrent-read concurrent-write parallel algorithm for detecting all squares in a string is presented. A tight lower bound shows that over general alphabets this is the fastest possible optimal algorithm. When p processors are available the bounds become 0(fnl;gnl +loglogrl+p/n12p).

BACKGROUND Engagement has emerged as a significant cross-cutting concern within the development of Web-based interventions. There have been calls to institute a more rigorous approach to the design of Web-based interventions, to increase both the quantity and quality of engagement. One approach would be to use log-data to better understand the process of engagement and patterns of use. However,...
