Computerized Generation of Endodontic Files by Reproducing the Flute Grinding Manufacturing Process
BioengineeringBackground: File fracture during root canal treatment in endodontics is a major concern for clinicians. The strength of the file is strongly dependent on its geometry, material, and working conditions; finite element simulations are used to understand ...

Cloth manipulation based on motion generation and shape prediction by EM*D-net
Transactions of the JSME (in Japanese), 2018 In this paper, we describe a motion planning method for cloth manipulation. We address the problem that only the current shape of the cloth product and its target shape are given. To accomplish this task, it is necessary to determine how to manipulate the cloth and to predict the manipulated shape of the cloth.

Coupling the solar surface and the corona: coronal rotation, Alfv\'en wave-driven polar plumes
, 2013 The dynamical response of the solar corona to surface and sub-surface perturbations depends on the chromospheric stratification, and specifically on how efficiently these layers reflect or transmit incoming Alfv\'en waves.

Probing the Upper Scorpius mass function in the planetary-mass regime
, 2013 We present the results of a deep ZYJ near-infrared survey of 13.5 square degrees in the Upper Scorpius (USco) OB association. We photometrically selected ~100 cluster member candidates with masses in the range 30-5 Jupiters, according to state-of-the-art

A generic method to construct new customized-shaped haotic systems using the relative motion concept
Nonlinear Analysis: Modelling and Control, 2016 Constructing chaotic systems tailored for each particular real-world application has been a long-term research desideratum. We report a solution for this problem based on the concept of relative motion. We investigate the periodic motion on a closed contour of a coordinate frame in which a chaotic system evolves.

Radial Velocities as an Exoplanet Discovery Method
, 2017 The precise radial velocity technique is a cornerstone of exoplanetary astronomy. Astronomers measure Doppler shifts in the star's spectral features, which track the line-of/sight gravitational accelerations of a star caused by the planets orbiting it ...
