Tracing evolutionary links between species [PDF]

open access: yes, 2014
The idea that all life on earth traces back to a common beginning dates back at least to Charles Darwin's {\em Origin of Species}. Ever since, biologists have tried to piece together parts of this `tree of life' based on what we can observe today ...

Stress assessment of welded joints in railway bogie frame

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Railway bogie frames are commonly constructed by welding several components. For a frame design, it is vital that all its welded joints have satisfactory strength and durability during their service life. This paper focuses on as-weld joints.

Computing the Distribution of a Tree Metric [PDF]

open access: yes, 2008
The Robinson-Foulds (RF) distance is by far the most widely used measure of dissimilarity between trees. Although the distribution of these distances has been investigated for twenty years, an algorithm that is explicitly polynomial time has yet to be ...

Torsional rigidity of steel square tubes with elastic anisotropy

open access: yesNihon Kikai Gakkai ronbunshu, 2016
Elastic moduli of metal sheets have planar anisotropy determined by crystalline texture. Texture control is effective in raising Young's modulus of steel sheets in some directions on the plane.

Comparison of fine structural mice via coarse iteration [PDF]

open access: yes, 2014
Let M be a fine structural mouse. Let D be a fully backgrounded L[E]-construction computed inside an iterable coarse premouse S. We describe a process comparing M with D, through forming iteration trees on M and on S.
