An elastic rod in frictional contact with a rigid cylinder
Pedro Miguel Nunes Pereira de Almeida Reis, Tomohiko Sano, Paul Grandgeorge
We investigate the load transmission along an elastic rod of finite cross-section in contact with a rigid cylinder, as system often referred to as the generalized capstan problem. In the presence of friction, the idealized classic capstan equation predicts ...
PERGAMON-ELSEVIER SCIENCE LTD2022X-ray pulsar-based GNC system for formation flying in high Earth orbits
Volker Gass, Camille Sébastien Pirat
In this paper, comprehensive pulsar-based Guidance, Navigation and Control (GNC) system is designed and applied to satellites formation flying. The complete autonomy of the X-ray pulsar navigation technology provides both absolute and relative positioning ...
PERGAMON-ELSEVIER SCIENCE LTD2020Effect of spilling from adjacent orifices on the velocity field and pressures in front of needle stop-logs
Giovanni De Cesare, Azin Amini, Cédric Bron, Ivan Stojnic
In this study, the effect of spilling from neighboring sluice gates on stop-logs was experimentally investigated on a 1:65 physical scale model comprised of a double arch dam, a reservoir area, six spillway orifices and two stop-logs. Two types of measurem ...
2018High Performance Computing Simulations of Dynamic Fragmentation in Brittle Materials
The aim of this thesis is to investigate the mechanisms behind dynamic fragmentation. This phenomenon occurs in a material when a blast or impact loading nucleates multiple cracks, whose propagation and coalescence break the specimen into fragments. Althou ...
EPFL2015Alignment of Multiple Configurations Using Hierarchical Models
We describe a method for aligning multiple unlabeled configurations simultane- ously. Specifically, we extend the two-configuration matching approach of Green and Mardia (2006) to the multiple configuration setting. Our approach is based on the in- troduct ...
2009Traveling liquid bridges in unsaturated fractured porous media
Interplay between capillary, gravity and viscous forces in unsaturated fractures gives rise to a range of complex flow phenomena. Evidence of highly intermittent fluxes, preferential and sustainable flow pathways lead to potentially significant flow focusi ...
Kluwer Academic Publishers, Springer2007The RNA degradosome: life in the fast lane of adaptive molecular evolution
In Escherichia coli, the multi-enzyme RNA degradosome contributes to the global, posttranscriptional regulation of gene expression. The degradosome components are recognized through natively unstructured "microdomains" comprising as few as 15-40 amino acid ...
