Can Drag Force Suppress Fermi Acceleration in a Bouncer Model?
(Mathematical Problems in Engineering, 2009-01-01) [Artigo]
Some dynamical properties for a bouncer model-a classical particle of mass m falling in the presence of a constant gravitational field g and hitting elastically a periodically moving wall-in the presence of drag force that ...
Cobordism of maps of locally orientable Witt spaces
(Publicationes Mathematicae-debrecen, 2019-01-01) [Artigo]
The aim of this work is to present some remarks on cobordism of normally nonsingular maps between compact locally orientable Witt spaces. By using the Wu classes defined by Goresky and Pardon, we give a definition of ...
Multimedia Retrieval Through Unsupervised Hypergraph-Based Manifold Ranking
(Ieee Transactions On Image Processing, 2019-12-01) [Artigo]
Accurately ranking images and multimedia objects are of paramount relevance in many retrieval and learning tasks. Manifold learning methods have been investigated for ranking mainly due to their capacity of taking into ...
