Synchronous motion of two vertically excited planar elastic pendula

Elastic property of vertically aligned nanowires.

An atomic force microscopy (AFM) based technique is demonstrated for measuring the elastic modulus of individual nanowires/nanotubes aligned on a solid substrate without destructing or manipulating the sample. By simultaneously acquiring the topography and lateral force image of the aligned nanowires in the AFM contacting mode, the elastic modulus of the individual nanowires in the image has be...

Synchronous Elastic Circuits

Synchronous elastic circuits (also known as latency-insensitive and latency-tolerant) behave independently of the latencies of computations and communication channels. For example, the three sequences are an acceptable behavior of an elastic adder with input channels X, Y and output channel Z, where the absence of transfer on a particular channel at a given cycle is indicated by *. Indeed, the ...

Synchronization of coupled self-excited elastic beams

The behavior of four coupled self-excited elastic beams is numerically studied using the finite-difference method. Self-excitation is modeled by adding a van der Pol damping term. Coupling based on shared boundary conditions at the roots of the beams is proposed, and the influence of the coupling on the dynamics is analyzed. Time and space correlation coefficients are employed to measure the de...

Planar Motion

Structure And Motion From Two Perspective Views Via Planar Patch

We present a method which uses both a planar patch and points for an analysis of time-varying imagery. From our theory. two pieces of information are required for the unique recovery of Structure from motion. One is the image motion of a plane and the other ODe is the image motion of points not on the plane. For the former. one needs four points while for the latter one need two points. Our tec...
