Multiple reflections are usually considered to be noise and many methods have been developed to attenuate them. However, similarly to primary reflections, multiple reflections are created by subsurface reflectors and contain their reflectivity information. We can image surface related multiples, regarding the corresponding primaries as the sources. Traditional source-receiver migration assumes ...

Distributed channel coding and network coding techniques are means employed to improve the performance of cooperative transmissions. This paper studies the BLER performance provided by a cooperative scheme that combines distributed channel coding and network coding for multiple sourcemultiple relay architectures, within which the number of available relays is smaller than the number of sources....

Both multiple source data mining and streaming data mining problems have attracted much attention in the past decade. In contrast to traditional association-rule mining, to capture the quantitative association knowledge, a new paradigm called Ratio Rule (RR) was proposed recently. We extend this framework to mining ratio rules from multiple source data streams which is a novel and challenging p...

MOMIS (Mediator EnvirOnment for Multiple Information Sources) is an Open Source Data Integration system able to aggregate data coming from heterogeneous data sources (structured and semistructured) in a semi-automatic way. DataRiver is a Spin-Off of the University of Modena and Reggio Emilia that has re-engineered the MOMIS system, and released its Open Source version both for commercial and ac...

The Big Data era features a huge amount of data that are contributed by numerous sources and used bymany critical data-driven applications. Due to the varying reliability of sources, it is common to see conflicts among the multi-source data, making it difficult to determine which data sources to trust. Recently, truth discovery has emerged as a means of addressing this challenging issue by dete...

In the future, competitive advantages will be given to organisations that can extract valuable information from massive data and make better decisions. In most cases, this data comes from multiple sources. Therefore, the challenge is to aggregate them into a common framework in order to make them meaningful and useful.This paper will first review the most important multi-criteria decision analy...
