Autonomous Tissue Scanning under Free-Form Motion for Intraoperative Tissue Characterisation

open access: yes, 2020
In Minimally Invasive Surgery (MIS), tissue scanning with imaging probes is required for subsurface visualisation to characterise the state of the tissue. However, scanning of large tissue surfaces in the presence of deformation is a challenging task for

Shape identification method for specified deformed mode of free-form shells

open access: yesNihon Kikai Gakkai ronbunshu, 2014
In this paper, we present a shape identification method of free-form shells for controlling the static deformation mode to the desired one. It is assumed that the shell is varied in the out-of-plane direction to the surface and the thickness is constant.

An inexact Newton-Krylov algorithm for constrained diffeomorphic image registration [PDF]

open access: yes, 2015
We propose numerical algorithms for solving large deformation diffeomorphic image registration problems. We formulate the nonrigid image registration problem as a problem of optimal control.

Parameter-free shape identification method for frame structure with desired static deformation

open access: yesNihon Kikai Gakkai ronbunshu, 2015
In this paper, a free form optimization method is proposed for achieving a desired static deformation of a frame structure. Deformation control is one of the important problems in stiffness design of frame structures, and it also enables to give a ...

R-Symmetries and Curvature Constraints in A-Twisted Heterotic Landau–Ginzburg Models

open access: yesParticles, 2023
In this paper, we discuss various aspects of a class of A-twisted heterotic Landau–Ginzburg models on a Kähler variety X. We provide a classification of the R-symmetries in these models which allow the A-twist to be implemented, focusing on the case in ...

Couplings between a collection of BF models and a set of three-form gauge fields

open access: yes, 2007
Consistent interactions that can be added to a free, Abelian gauge theory comprising a collection of BF models and a set of three-form gauge fields are constructed from the deformation of the solution to the master equation based on specific ...

"Wet-to-Dry" Conformational Transition of Polymer Layers Grafted to Nanoparticles in Nanocomposite [PDF]

open access: yes, 2010
The present communication reports the first direct measurement of the conformation of a polymer corona grafted around silica nano-particles dispersed inside a nanocomposite, a matrix of the same polymer.

Spline-based specimen shape optimization for robust material model calibration

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
Identification from field measurements allows several parameters to be identified from a single test, provided that the measurements are sensitive enough to the parameters to be identified.
