Computability of Koch Curve and Koch Island

Koch curve is known as a typical self-similar set on Euclidean plane. Koch island is a closed set surrounded by three copies of Koch curve. We investigate them from the viewpoint of computability. In this paper, we define computability of a curve and that of a closed set as an application of classical computable analisys to Euclidean spaces and show that Koch curve is a computable curve and bot...

To the Gates of HAL: A HAL Tutorial

Experience using constraint programming to solve real-life problems has shown that finding an efficient solution to the problem often requires experimentation with different constraint solvers or even building a problem-specific constraint solver. HAL is a new constraint logic programming language expressly designed to facilitate this process. It provides semi-optional type, mode and determinis...

Superior Koch Curve

In this paper, the author presents the design of Superior Koch Curve with different scaling factor, which has wide applications in Fractals Graphics. The proposed curve has been designed using the technique of superior iteration. The Koch curve is the limiting curve obtained by applying the self similar divisions to infinite number of times but in Superior Koch Curve scaling factor is based on ...

HAL Exoskeleton Training

The hybrid assistive limb (HAL) exoskeleton provides rehabilitation of the motor skills of chronic spinal chord injury (SCI) patients as well as alleviation of chronic neuropathic pain (CNP). The HAL device uses bioelectric signals to activate robotic support of voluntary movement during bodyweight supported treadmill training (BWSTT).
