Time-scaled coordination of multiple manipulators

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
Coordinating multiple manipulators in a shared workspace while considering their dynamics is an important problem. This problem of collision-free coordination arises in assembly, materials transfer, and welding workcells. Previous approaches that considered robot dynamics have typically been restricted to coordinating just two or three manipulators ...

Multiple time-scales in network-of-networks

2016 American Control Conference (ACC), 2016
This paper examines a multiple time-scale system where each layer of time-scale dynamics corresponds to a network. Coupling between layers induces a network-of-networks dynamic system. Assuming a hierarchical interaction structure between network time-scale layers with sufficient time-scale differences, layers can be studied under a separation ...

Multiple time scales in multi‐state models

Statistics in Medicine, 2013
In multi‐state models, it has been the tradition to model all transition intensities on one time scale, usually the time since entry into the study (‘clock‐forward’ approach). The effect of time since an intermediate event has been accommodated either by changing the time scale to time since entry to the new state (‘clock‐back’ approach) or by ...

Multiple time scale analysis of lasers

AIP Conference Proceedings, 2000
In many areas of engineering and science the mathematical formulation leads to nonlinear problems that are difficult to solve even numerically. Many of the numerical difficulties come from the stiffness of the equations due to the presence of small or large parameters multiplying time derivatives. Very often, the solution exhibits different time scales

Multiple time scales in survival analysis

Lifetime Data Analysis, 1995
In some problems in survival analysis there may be more than one plausible measure of time for each individual. For example mileage may be a better indication of the age of a car than months. This paper considers the possibility of combining two (or more) time scales measured on each individual into a single scale.

Learning to Control at Multiple Time Scales

2003
In reinforcement learning the interaction between the agent and the environment generally takes place on a fixed time scale, which means that the control interval is set to a fixed time step. In order to determine a suitable fixed time scale one has to trade off accuracy in control against learning complexity.
