High Strain Rate Properties of High Strength Steel Sheets

open access: yesInternational Journal of Automotive Engineering, 2011
High strain rate properties of sheet steel largely depend on its strength level and strengthening mechanisms. The strain rate sensitivity of flow stress has a close relation with the hardness of a softer phase, which indicates superior strain rate ...

Axiomatic opportunities and obstacles for inferring a species tree from gene trees [PDF]

open access: yes, 2014
The reconstruction of a central tendency `species tree' from a large number of conflicting gene trees is a central problem in systematic biology. Moreover, it becomes particularly problematic when taxon coverage is patchy, so that not all taxa are ...

Which phylogenetic networks are merely trees with additional arcs? [PDF]

open access: yes, 2015
A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...

Visuospatial Working Memory Tasks May Not Reduce the Intensity or Distress of Intrusive Memories

open access: yesFrontiers in Psychiatry, 2022
Cognitive interventions involving visuospatial tasks, such as the game “Tetris” have demonstrated efficacy in reducing the frequency of intrusive memories.

Hydrogen Embrittlement Evaluation Methods for Ultra-high Strength Steel Sheets for Automobiles

open access: yesInternational Journal of Automotive Engineering, 2010
In order to apply ultra-high strength steel sheets with tensile strength of 980MPa or higher to automobiles, it is necessary to ensure the safety of steel parts against hydrogen embrittlement (HE).

Multiple output production with undesirable outputs : an application to nitrogen surplus in agriculture [PDF]

open access: yes, 2002
Many production processes yield both good outputs and undesirable ones (e.g., pollutants). In this article we develop a generalization of a stochastic frontier model that is appropriate for such technologies.

Phylogenetic mixtures on a single tree can mimic a tree of another topology [PDF]

open access: yes, 2007
Phylogenetic mixtures model the inhomogeneous molecular evolution commonly observed in data. The performance of phylogenetic reconstruction methods where the underlying data is generated by a mixture model has stimulated considerable recent debate.

Comparative study of Steel-FRP, FRP and steel reinforced coral concrete beams in their flexural performance [PDF]

open access: yes, 2020
In this paper, a comparative study of Carbon Fiber Reinforced Polymer (CFRP) Bar and Steel-Carbon Fiber Composite Bar (SCFCB) reinforced coral concrete beams are made through a series experimental tests and theoretical analysis.

Majorisation ordering of measures invariant under transformations of the interval [PDF]

open access: yes, 2010
PhDMajorisation is a partial ordering that can be applied to the set of probability measures on the unit interval I = [0, 1). Its defining property is that one measure μ majorises another measure , written μ , if R I fdμ R I fd for every ...
