[1] We investigate the behavior of simulated slow slip events using a rate and state friction model that is steady state velocity weakening at low slip speeds but velocity strengthening at high slip speeds. Our simulations are on a one-dimensional (line) fault, but we modify the elastic interactions to mimic the elongate geometry frequently observed in slow slip events. Simulations exhibit a nu...

Abstract---The steady flow of a second order fluid through constricted tube with slip velocity at wall is modeled and analyzed theoretically. The governing equations are simplified by implying no slip in radial direction. Based on Karman Pohlhausen procedure polynomial solution for axial velocity profile is presented. Expressions for pressure gradient, shear stress, separation and reattachment ...

Many applications require rotary platforms and slip rings to carry electrical power and signals to and from the rotating system. Standard slip ring technology involves forming an electrical path with rotating rings contacted by a stationary sliding contact or brush. In the world of analog signals, analog video, and low speed digital data, the specification of a slip ring for a set of signals an...

The extensor apparatus of the finger is a complex structure and injury can lead to significant digital dysfunction. Closed central slip injuries may be missed or diagnosis delayed because of lack of an open wound and often no radiographic abnormality, and can result in boutonniere deformities if untreated. This study aimed to quantify the number of patients attending with closed central slip in...

During the 2011 magnitude 9 Tohoku-oki earthquake, very large slip occurred on the shallowest part of the subduction megathrust. Quantitative information on the shallow slip is of critical importance to distinguishing between different rupture mechanics and understanding the generation of the ensuing devastating tsunami. However, the magnitude and distribution of the shallow slip are essentiall...

Incidental finding of an accessory slip of the piriformis muscle in the gluteal region is reported. Following routine dissection of the gluteal region in three formalin-fixed cadavers, an accessory slip of the piriformis was observed. The accessory slip was cleaned, attachments were identified, and dimensions were measured in two parts as fleshy and tendinous parts with a graduated scale to the...

Slowly compressed microcrystals deform via intermittent slip events, observed as displacement jumps or stress drops. Experiments often use one of two loading modes: an increasing applied stress (stress driven, soft), or a constant strain rate (strain driven, hard). In this work we experimentally test the influence of the deformation loading conditions on the scaling behavior of slip events. It ...

Phase-slip lines can be viewed as dynamically created Josephson junctions in a homogeneous superconducting film. In contrast to phase-slip centers, phase-slip lines occur in wide superconducting strips, where the order parameter may vary in two dimensions. We investigated phase-slip lines in two different materials using several methods. We observed Shapiro steps under microwave radiation, whic...

We investigate theoretically the influence of hydrodynamic slip at the surface of a nanofluidic channel on the efficiency with which electrokinetic phenomena can be used to convert hydrostatic energy to electrical power. Slip is introduced by applying the Navier boundary condition to the pressure-driven and the electro-osmotic components of the fluid velocity. A strong enhancement in the effici...

I. INTRODUCTION There are two main categories of object slip: linear and rotational. During linear slip, the object maintains its orientation with respect to the local end-effector frame but gradually slides out of the robot fingers. During rotational slip, the center of mass of the object tends to rotate about an axis normal to the grasp surface, although the point of contact with the robot's ...
