Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Characterization and control of self-motions in redundant manipulators [PDF]
The presence of redundant degrees of freedom in a manipulator structure leads to a physical phenomenon known as a self-motion, which is a continuous motion of the manipulator joints that leaves the end-effector motionless. In the first part of the paper,

Movement Disorders, EarlyView.Abstract Background Spastic paresis, resulting from central nervous system lesions, significantly impairs functional performance. In the framework of the International Classification of Functioning, Disability, and Health, functional performance was defined as functioning at the activity level in relation to the impairment of body functions and ...
