A discontinuous Galerkin finite element method for an optimal control problem related to semilinear parabolic PDE’s is examined. The schemes under consideration are discontinuous in time but conforming in space. Convergence of discrete schemes of arbitrary order is proven. In addition, the convergence of discontinuous Galerkin approximations of the associated optimality system to the solutions ...

Effects of trawling on Posidonia oceanica beds. Posid onia beds between Capo Circeo and Terracina (Mid-Tyrrhenian Sea) were studied as part of a study of the effects of illegal trawling inside th e three m ile limit.

In this paper, we discuss rough inclusions defined in Rough Mereology – a paradigm for approximate reasoning introduced by Polkowski and Skowron – as a basis for common models for rough as well as fuzzy set theories. We justify the point of view that tolerance (or, similarity) is the motif common to both theories. To this end, we demonstrate in Sect. 6 that rough inclusions (which represent a h...

The reported overall subfertility rate in Kenia is 26.1% with 50% attributed to tubal factors and 15% due to male factors. This is probably an underestimation taking into consideration that due to the stigma and myths of the disease, many couples are seeking alternative care from religious sects, witchdoctors, herbalists. Because the costs associated with IVF in private centres are only afforda...
