In this paper we prove a central limit theorem of Lindeberg-Feller type on the space Pn- It generalizes a theorem obtained by Faraut ([!]) for n = 2. To state and prove this theorem

Keats’s Isabella contains many references to working bodies, and this paper will examine how the labouring body is represented based on both the class of the labourer and the

Before going on with the description of the main features of this paper, we will need some further notations. Therefore, Choquet Theory applies and every positive positive

We expected that anticipation of tennis shot direction would be made possible when simulations contained dynamic differences in shot direction (Huys et al., 2008),

In this study, we test the hypothesis that patients with HD may be impaired in their recognition of positive as well as negative emotional signals, by
