A novel wheel-track hybrid electric powered wheelchair for stairs climbing

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
Aiming at efficient locomotion on the ground and safe stairs climbing for aged or physical disabled people, a wheel-track hybrid electric powered wheelchair (EPW) is designed, analyzed, and demonstrated extensively on various conditions. We first present

Analysis of Mechanical Oscillations by Speckling [PDF]

Applied Optics, 1972
The application of the speckle phenomenon to the analysis of in-plane translations and oscillations is first reviewed briefly. Then a practical method of investigating out-of-plane rotations (tilts) even in the presence of in-plane movements is studied.

Multi-class, multi-functional design of photonic topological insulators by rational symmetry-indicators engineering

Nanophotonics, 2021
An explicit topology optimization-based design paradigm is proposed for the design of photonic topological crystalline insulators (TCIs). To strictly guarantee the topological property, rational engineering of symmetry-indicators is carried out by ...

Symplectic superposition solutions for free in-plane vibration of orthotropic rectangular plates with general boundary conditions

Scientific Reports, 2023
This work reports new analytic free in-plane vibration solutions for orthotropic non-Lévy-type rectangular plates, i.e., those without two opposite edges simply supported, by the symplectic superposition method (SSM), which has never been applied to in ...
