Modelling of transitional workpiece deformation in end-milling considering workpiece rigidity reduction

open access: yesNihon Kikai Gakkai ronbunshu, 2023
Workpiece rigidity during end-milling processes decreases monotonously. Reduction rates of the rigidity become large when the end-milling operations have large cutting stock such as carve out machining.

Stress matrices and global rigidity of frameworks on surfaces [PDF]

open access: yes, 2015
In 2005, Bob Connelly showed that a generic framework in $\bR^d$ is globally rigid if it has a stress matrix of maximum possible rank, and that this sufficient condition for generic global rigidity is preserved by the 1-extension operation.

Role of barium enema examination for the diagnosis of submucosal invasion depth in T1 colorectal cancers

open access: yesCancer Imaging, 2021
Background The indication for endoscopic resection for submucosally invasive colorectal cancer (T1-CRC) depends on the preoperative diagnosis of invasion depth.

Counting and effective rigidity in algebra and geometry

open access: yes, 2018
The purpose of this article is to produce effective versions of some rigidity results in algebra and geometry. On the geometric side, we focus on the spectrum of primitive geodesic lengths (resp., complex lengths) for arithmetic hyperbolic 2-manifolds ...

Gradient integrability and rigidity results for two-phase conductivities in two dimensions [PDF]

open access: yes, 2014
This paper deals with higher gradient integrability for σ-harmonic functions u with discontinuous coefficients σ, i.e. weak solutions of div(σ∇u)=0 in dimension two.

Properties of the histogram location approach and the extent and change of downward nominal wage rigidity in the EU [PDF]

open access: yesThe European Journal of Comparative Economics, 2006
The histogram location approach has been proposed by Kahn (1997) to estimate the fraction of wage cuts prevented by downward nominal wage rigidity.

Partially and globally overdetermined problems of elliptic type

open access: yesAdvances in Nonlinear Analysis, 2012
We review some classical and recent results on overdetermined problems both in bounded and unbounded domains, and we discuss how to recover, in some circumstances, a globally overdetermined problem from a partially overdetermined one.

Exploring Protein Cavities through Rigidity Analysis

open access: yesMolecules, 2018
The geometry of cavities in the surfaces of proteins facilitates a variety of biochemical functions. To better understand the biochemical nature of protein cavities, the shape, size, chemical properties, and evolutionary nature of functional and ...

Some rigidity results on critical metrics for quadratic functionals [PDF]

open access: yes, 2014
In this paper we prove rigidity results on critical metrics for quadratic curvature functionals, involving the Ricci and the scalar curvature, on the space of Riemannian metrics with unit volume. It is well-known that Einstein metrics are always critical

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]

open access: yes, 2011
We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.
