A substantial amount of data is collected through surveys conducted in Africa, by national statistics offices, international donor organisations, research institutions, and the private sector. However, data management at African national statistics offices is hampered by limited resources. An option for data curation in African countries is the establishment of dedicated institutions for data p...

Last decade, numerous giant data center networks are built to provide increasingly fashionable web applications. For two integers m≥0 and n≥2, the m-dimensional DCell network with n-port switches Dm,n n-dimensional BCDC Bn have been proposed. As a generalization of connectivity, structure (substructure) connectivity was recently Let G H be connected graphs. F set whose elements subgraphs G, eve...

Temporal association rule mining promises the ability to discover time-dependent correlations or patterns between events in large volumes of data. To date, most temporal data mining research has focused on events existing at a point in time rather than over a temporal interval. In comparison to static rules, mining with respect to time points provides semantically richer rules. However, accommo...

In this paper we present CM-Well, a clustered, horizontally scalable data store for linked data. We discuss the key architectural principals of the system and introduce distinguishing features. Thomson Reuters has been running CM-Well in production for over two years, across multiple data centers. The system provides data, via API, to a number of our online products.

The method of auxiliary sources (MAS) presents a promising alternative to methods based on discretization, currently used for solving scattering problems. The optimal choice of the auxiliary surface and the proper allocation of radiation centers play a crucial role in ensuring accuracy and stability of the MAS. This approach is considered an open issue and can be investigated numerically. In th...
