The unique lure of the America Cup Yachting race and the generous (read lavish) resources allocated to the research of the best ratio between design and performance in its history-loaded J-Class have defined some of the most spectacular ocean ships of the last hundred years. As a software modelling experiment, we have chosen to re-imagine an engineering journey, by redrawing with contemporary tools a graceful design of the 1930s: the Ranger F yacht that became the Lionheart vessel in 2010, after more than seven de...

The Analytic Hierarchy Process (AHP) is considered a flexible and efficient mathematical tool in approaching the complex decision processes. The AHP method allows the reduction of the complex decisions to comparisons by pairs and, finally, to the synthesis of the results, contributing to the capture of the subjective and objective aspects of the decision. Also, the AHP method allows the check of the coherence for the evaluations made by the decision makers, thus leading to the reduction of the prejudices in the de...

The Danube Delta dynamics formation and expansion represent the motivation of the study included in this paper. The results of soil studies made possible to develop the Danube Delta genesis maps [7]. That informationпїЅs are the input data and the validation data for the numerical flow studies of the Danube River. The study of the formation of new territories has been developed by the Computational Fluid Dynamics (C.F.D.) method. There were modelled in three dimensions the maps for Danube River Basin flowing into ...
