Elastic oscillations of cylindrical fuses

A fast current pulse causes a material to heat and undergo rapid expansion. We calculate the response of a cylindrically shaped material to a pulse on the microsecond time scale. The first step is to obtain the breathing modes of elastic oscillation of the cylinder. These modes are calculated using a Rayleigh–Ritz variational method introduced by Demarest for cubes. The boundary conditions are ...

The Robot Crawler Number of a Graph

Information gathering by crawlers on the web is of practical interest. We consider a simplified model for crawling complex networks such as the web graph, which is a variation of the robot vacuum edge-cleaning process of Messinger and Nowakowski. In our model, a crawler visits nodes via a deterministic walk determined by their weightings which change during the process deterministically. The mi...

In-pipe inspection robot system with active steering mechanism

I n this paper, we present a robot system for inpipe inspection of underground urban gas pipelines. The robot is configured as an articulated structure like a snake with a tether cable. Two active driving vehicles are located in front and rear of the system, and passive modules such as a control module are chained between the active vehicles. The proposed robot has outstanding mobility oflered ...

Sensing capabilities of linear elastic cylindrical fingers

Edward J. Nicolson and Ronald S. Fearing Department of EE&CS University of California Berkeley, CA 94720 Abstract A linear elastic plane strain model for a cylindrical nger with a solid core and elastic surface is developed. This model is used to determine the subsurface strain impulse responses as well as pressure distributions in the contact region for indentation of the cylinder by rigid obj...
