A note on attractivity for the intersection of two discontinuity manifolds [PDF]
In piecewise smooth dynamical systems, a co-dimension 2 discontinuity manifold can be attractive either through partial sliding or by spiraling. In this work we prove that both attractivity regimes can be analyzed by means of the moments solution, a ...

Simple dynamics underlying the survival behaviors of ciliates
Ciliates are swimming microorganisms in aquatic environments. Habitats where ciliates accumulate include nutrient-rich solid–liquid interfaces such as pond bottom walls and waterweed surfaces. The ciliates stay near the walls to survive.

Creeping slopes in NW Himalaya and Joshimath slide: constraints from GPS measurements
Slow slope movement is very common in the Himalayan region. In most cases, the topsoil, weathered rock mass, debris of paleo-landslide or of glacial origin, etc. slowly slides until it stabilizes or fails.

The motion of a pushed, sliding workpiece [PDF]
It occurs frequently in robotic applications that a robot manipulates a workpiece which is free to slide on a work surface. Because the pressure distribution supporting the workpiece on the work surface cannot in general be known, the motion of the workpiece cannot be calculated uniquely. The authors find the locus of centers of rotation of a workpiece

Effect of Characteristics of Ground Motion on Seismically Induced Sliding Surface of Slopes
The seismic performance of slopes is typically evaluated with a pseudo-static method using equivalent horizontal load or with Newmark sliding block analysis. In both procedures, the definition of the potential sliding surface is a required input.

Stabilization of Switched Time-Delay Linear Systems through a State-Dependent Switching Strategy
This paper considers the problem of stabilizing switched time-delay linear systems through a state-dependent switching strategy. In contrast to the existing works, we adopt a less restrictive assumption of the system, and show that this assumption is ...

A numerical model to simulate the transient frictional viscoelastic sliding contact
Sliding motion has always been one of the major concerns when it comes to the analysis of viscoelastic contact problems. A new model simulating the transient sliding contact of smooth viscoelastic surfaces is developed in this paper.
