Riemannian Submersions with Discrete Spectrum
(SPRINGERNEW YORK, 2012)
We prove some estimates on the spectrum of the Laplacian of the total space of a Riemannian submersion in terms of the spectrum of the Laplacian of the base and the geometry of the fibers. When the fibers of the submersions ...
Maslov index in semi-Riemannian submersions
(SPRINGER, 2010)
We study focal points and Maslov index of a horizontal geodesic gamma : I -> M in the total space of a semi-Riemannian submersion pi : M -> B by determining an explicit relation with the corresponding objects along the ...
Riemannian submersions of open manifolds which are flat at infinity
(Birkhauser Verlag AgBaselSuíça, 1999)
Semi-submersible hub platform with and internal dock model testing
(ASMESan Francisco, 2014-06-08)
The recent discoveries and development of the Pre-salt reservoir in Brazilian coast require a new logistical model for crew transportation and transhipment to the drilling and oil rigs due to the large distance from coast, ...
Survival strategies on a semi-arid island: submersion and desiccation tolerances of fiddler crabs from the Galapagos Archipelago
(Springer, 2021-01-01)
During tidal cycles, fiddler crabs undergo alternating periods of submersion and desiccation. We compare physiological and biochemical adjustments to submersion and desiccation challenge in two gelasminids from the Galapagos ...
Experimental study on vortex-induced motions of a semi-submersible platform with four square columns, Part I: Effects of current incidence angle and hull appendages
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
An experimental study on Vortex-Induced Motion (VIM) of the semi-submersible platform concept with four square columns is presented. Model tests were carried out to check the influence of different headings and hull ...
