Research ArticleOpen accessIn the keywordsMultilevel Evaluation of Coulomb Lattice Sums of Charge SystemsV. Ilyin, A. Brandt, I. SuwanProblem statement: Due to the long range nature of interactions of the N-body systems, direct computation of the Coulomb potential energy involves O(N2) operations. To decrease such complexity, a simple Multilevel Summation method has been developed. Approach: In the frame of the Multilevel Summation method, the two-body interaction is decomposed into two parts: a local part and a smooth part. … …Journal of Mathematics and Statistics, Vol. 8, Issue 3 · 11 Sep 2012 · 7,381 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContact with Nature and Children’s Wellbeing in Educational SettingsGiuseppe Carrus, Sabine Pirchio, Ylenia Passiatore et al.Problem statement: The study explores the role of the spatial-physical features of the environment for the functioning of educational institutions. Previous research in the field of environmental psychology showed how physical characteristics of learning environments might be linked to positive or negative outcomes in terms of learning attitudes and behaviors. In particular, there is consistent empirical evidence showing that contact … …Journal of Social Sciences, Vol. 8, Issue 3 · 26 Mar 2012 · 14,402 accessesView PDFCite
