Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors and Rupture Velocity

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Vladislav Yastrebov

The rupture dynamics of earthquakes span a considerable range, from slow to super-shear ruptures. Rupture speed has a major influence on the generation of strong ground motions, yet our understanding of the mechanisms causing these variations in the ruptur ...

Spinal and Supraspinal Control of the Direction of Stepping during Locomotion

Pavel Musienko

Most bipeds and quadrupeds, in addition to forward walking, are also capable of backward and sideward walking. The direction of walking is determined by the direction of stepping movements of individual limbs in relation to the front-to-rear body axis. Our ...

Reaching and grasping kitchenware objects

Aude Billard, Ashwini Shukla, José Santos-Victor, Alexandre Bernardino

We integrate software components that allow ef- ficient and successful grasping of kitchenware objects. The contributed components include: The object pose detector, the gripper reaching motion and the grasp hypothesis selection. The object pose detector o ...

Electromechanical Coupling In Cardiac Dynamics: The Active Strain Approach

Alfio Quarteroni, Fabio Nobile

The coupling between cardiac mechanics and electric signaling is addressed in a nonstandard framework in which the electrical potential dictates the active strain (not stress) of the muscle. The physiological and mathematical motivations leading us to this ...

Distributed motion planning for ground objects using a network of robotic ceiling cameras

We study a distributed approach to path planning. We focus on holonomic kinematic motion in cluttered 2D areas. The problem consists in defining the precise sequence of roto-translations of a rigid object of arbitrary shape that has to be transported from ...

Contactless rotational concentric microviscometer

Peter Ryser, Eric Meurville, Sigfrid Straessler, Emeric Grandjean

We investigated the feasibility of a concentric rotational microviscometer which is actuated remotely. This type of sensor might find application in vivo as a passive implant. The heart of the sensor is a cylindrical rotor, actuated from a distance of up t ...

The hydrodynamic Chaplygin sleigh

We consider the motion of rigid bodies in a potential fluid subject to certain nonholonomic constraints and show that it is described by Euler-Poincare-Suslov equations. In the two-dimensional case, when the constraint is realized by a blade attached to th ...

Optical stability of axially chiral push-pull-substituted buta-1,3dienes: Effect of a single methyl group on the C60 surface

Pablo Rivera Fuentes

A new spin on C60: Axially chiral, pushpull buta-1,3-diene chromophores conjugated to vicinally methylated fullerenes (see picture) have high barriers of rotation about their chiral axes. These high barriers allowed their optical resolution and the determi ...

Automated Motion LoD with Rigid Constraints

Daniel Thalmann, Junghyun Ahn

Motion LoD (Level of Detail) is a preprocessing technique that generates multiple details of captured motion by eliminating joints. This LoD technique is applied to movie, game or VR environments for the purpose of improving speed of crowd animation. So fa ...

On The Stochastic Modeling Of Rigid Body Systems With Application To Polymer Dynamics

John Maddocks

The stochastic equations of motion for a system of interacting rigid bodies in a solvent are formulated and studied. Three-dimensional bodies of arbitrary shape, with arbitrary couplings between translational and rotational degrees of freedom, as arise in ...
