Bettering operation of dynamic systems by learning: A new control theory for servomechanism or mechatronics systems
A new concept called "betterment process" is proposed for the purpose of giving a learning ability of autonomous construction of a better control input to a class of multi-input multi-output servomechanism or mechatronics systems such as mechanical robots. Expand

Learning control theory for dynamical systems
Three types of learning control laws are proposed for mechanical or mechatronics systems with linear and nonlinear dynamics, which may be operated repeatedly at low cost. Given a desired output YdExpand

Effects of material strain rate sensitivity in low speed impact between two identical spheres
Abstract This paper investigates the effects of strain rate sensitivity on the impact of two identical spheres. The spheres made of SUJ2 steel were impacted by using pendulum setup. The coefficientsExpand

Articular cartilage repair. Rabbit experiments with a collagen gel-biomatrix and chondrocytes cultured in it.
To repair a full-thickness articular cartilage defect in rabbit knees, we developed a technique of using a collagen gel hardened by cultured allogeneic chondrocytes in it. The gel-chondrocyteExpand

Subjective results of laser surgery for allergic rhinitis.
Inferior turbinates of 389 patients with perennial allergic rhinitis were vaporized by a defocused carbon dioxide (CO2) laser beam, using specially designed handpieces. This laser surgery can be doneExpand

Simulation of the nonlinear vibration of a string using the cellular automation method
In this study, the nonlinear dynamic responses of a string were simulated using the cellular automaton (CA) method. The local rules were set for the amplitude of vibration and the decay rate ofExpand
