When studying for a doctoral degree (PhD), candidates submit a thesis that provides a critical review of the current state of knowledge of the thesis subject as well as the student’s own contributions ...

In the present paper, a simplified homogenized beam theory is used in the context of a numerical investigation regarding the dynamic behavior of a rotating composite hollow shaft. For this aim, a ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...

Microscope images could be obtained much more quickly -- rather than one pixel at a time -- thanks to a new imaging method for neutral atomic beam microscopes. It could ultimately lead to engineers ...

Abstract: The aim of this paper is to investigate a direct numerical method for solving a class of a fractional variational problem (FVP). The fractional derivative in the FVP is in the Caputo sense.

Deep-sea pressure structures, including submersibles, deep-sea space stations and delivery platforms, underwater gliders, subsea pipelines, ocean platforms, electronic cabins, etc., play an important ...

Cultural Heritage buildings are complex but of inestimable value. They requires the synergy of all involved communities. We assembled a large database of historical masonry towers through an extensive ...

Acequias, a network of water channels created by the Moors over 1,000 years ago, are being excavated and brought back to life to adapt to the crises of climate change. By Constant Méheut Constant ...
