The main obstacle for obtaining fast domain decomposition solvers for the spectral element discretizations of the 2-nd order elliptic equations was the lack of fast solvers for local internal problems on subdomains of decomposition and their faces. As was recently shown by Korneev/Rytov, such solvers can be derived on the basis of the specific interrelation between the stiffness matrices of the...

We present the analysis of the interrelation between two processes accounting for the spreading of an epidemics, and the information awareness to prevent its infection, on top of multiplex networks. This scenario is representative of an epidemic process spreading on a network of persistent real contacts, and a cyclic information awareness process diffusing in the network of virtual social conta...

In this paper we present a new and alternative approach for automatically classifying the email documents into a fuzzy hierarchical structure. We have used data mining and fuzzy logic techniques to solve this problem. The FISCRM model (based on the fuzzy synonymy interrelation and the fuzzy generality interrelation) is used to achieve a conceptual representation of the messages. A softclusterin...

The study attempts to highlight the interrelation between three central points in the ongoing debate on the political economy of development: viability, surplus, and class-formation. A case study of the development of rural labour systems in Northern Nigeria is meant to provide both a better qualitative and quantitative idea of this interrelation. After an analysis of the socio-economic effects...
