This essay explores the concept of figuration or configuration developed by Norbert Elias with the purpose to overcome the antinomies of structural functionalism and methodological individualism. The relationships of the concept of configuration with the categories of interdependency, function and coercion are studied within the context of his sociological theory. Based on the consideration of ...

The parareal algorithm, recalled in section 2 below, allows one to solve evolution equations on (possibly massively) parallel architectures. The two building blocks of the algorithms are a coarse-discretization predictor (solved sequentially) and a fine-discretization corrector (solved in parallel). First developed in Lions et al. (2000) and slightly modified in Bal and Maday (2002), which is t...

The main purpose of this paper is to introduce novel two-level overlapping 15 Schwarz methods for solving the Helmholtz equation. Among the most effective par16 allel two-level domain decomposition solvers for the Helmholtz equation on general 17 unstructured meshes, we mention the FETI-H method introduced by Farhat et al. [5], 18 and the WRAS-H-RC method introduced by Kimn and Sarkis [10]. FET...

Background: In recent decades, the incidence of children’s hematological malignancies has been increasing worldwide including Tunisia. Their severity is reflected in the importance of the medical, social and economic impact. This increase remains fully unexplained, and the involvement of genetic, environmental and occupational factors is strongly suspected. Materials and methods: Our study was ...

In the standard methodology for evaluating the Hawking radiation emanating from a black hole, the background geometry is fixed. Trying to be more realistic we consider a dynamical geometry for a two-dimensional charged black hole and we evaluate the Hawking radiation as a tunneling process. This modification to the geometry gives rise to a nonthermal part in the radiation spectrum. We exlore th...
