On -Elastica
Shigeki Matsutani, Hiroshi Nishiguchi, Kenji Higashida +2
In this paper, we investigate a transition from an elastica to a piece-wised elastica whose connected point defines the hinge angle ; we refer the piece-wised elastica $Λ_{ϕ_0…
Mathematics in Caging of Robotics
Hiroyasu Hamada, Satoshi Makita, Shigeki Matsutani
It is a crucial problem in robotics field to cage an object using robots like multifingered hand. However the problem what is the caging for general geometrical objects and robots…
An algebraic description of screw dislocations in SC and BCC crystal lattices
Hiroyasu Hamada, Shigeki Matsutani, Junichi Nakagawa +2
We give an algebraic description of screw dislocations in a crystal, especially simple cubic (SC) and body centered cubic (BCC) crystals, using free abelian groups and fibering str…
