Energy flow: image correspondence approximation for motion analysis [PDF]

Optical Engineering, 2016
We propose a correspondence approximation approach between temporally adjacent frames for motion analysis. First, energy map is established to represent image spatial features on multiple scales using Gaussian convolution. On this basis, energy flow at each layer is estimated using Gauss–Seidel iteration according to the energy invariance constraint ...

Unidirectional motion of C60-based nanovehicles using hybrid substrates with temperature gradient

Scientific Reports, 2023
With the synthesis of nanocar structures the idea of transporting energy and payloads on the surface became closer to reality. To eliminate the concern of diffusive surface motion of nanocars, in this study, we evaluate the motion of C60 and C60-based ...

A back-to-front derivation: the equal spacing of quantum levels is a proof of simple harmonic oscillator physics [PDF]

, 2009
The dynamical behaviour of simple harmonic motion can be found in numerous natural phenomena. Within the quantum realm of atomic, molecular and optical systems, two main features are associated with harmonic oscillations: a finite ground-state energy and

Anisotropic atomic motions in structural analysis by low energy electron diffraction [PDF]

Physical Review Letters, 1993
The structure of the √3 × √3 R30° overlayer formed by CO molecules adsorbed on a Ru(0001) was analyzed by low energy electron diffraction. Anisotropic atomic motions under the influence of thermal excitation were taken into account by adopting the concept of split positions.
