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 ...

X-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 ...

Effect 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 ...

High Performance Computing Simulations of Dynamic Fragmentation in Brittle Materials

Marco Vocialta

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 ...

Evaluation of the muscular activity duration in shoulders with rotator cuff tear using inertial sensors and electromyography

Kamiar Aminian, Alain Farron, Cyntia Duc

Shoulder disorders, including rotator cuff tears, affect the shoulder function and result in adapted muscle activation. Although these adaptations have been studied in controlled conditions, free-living activities have not been investigated. Based on the k ...

Interaction of a point charge with the surface of a uniaxial dielectric

Primoz Rebernik Ribic

We analyze the force on a point charge moving at relativistic speeds parallel to the surface of a uniaxial dielectric. Two cases are examined: a lossless dielectric with no dispersion and a dielectric with a plasma-type response. The treatment focuses on t ...

Alignment of Multiple Configurations Using Hierarchical Models

Yann Ruffieux

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 ...

Model for fretting wear of brittle ceramics

Abhishek Tewari

In selecting and designing materials for certain engineering applications, the resistance to material damage or removal of material from contacting surfaces in relative motion is an important factor. To determine these properties, laboratory tests are rout ...

Traveling liquid bridges in unsaturated fractured porous media

Dani Or

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 ...

The 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 ...
