Relaxed optimization for mode estimation in skid steering
— Skid-steered vehicles, by design, must skid in order to maneuver. The skidding causes the vehicle to behave discontinuously as well as introduces complications to the observati...

Fast contact force computation for nonpenetrating rigid bodies
A new algorithm for computing contact forces between solid objects with friction is presented. The algorithm allows a mix of contact points with static and dynamic friction. In co...

Analysis of Frictional Contact Models for Dynamic Simulation
Simulation of dynamic systems possessing unilateral frictional contacts is important to many industrial applications. While rigid body models are often employed, it is well establ...

Classifying Human Dynamics Without Contact Forces
We develop a classification algorithm for hybrid autoregressive models of human motion for the purpose of videobased analysis and recognition. We assume that some temporal statist...

A hard-constraint time-stepping approach for rigid multibody dynamics with joints, contact, and friction
We present a method for simulating rigid multibody dynamics with joints, contact, and friction. In this work, the nonsmooth contact and frictional constraints are represented by h...
