Lobelia dortmanna - light, growth strategy and zonation [PDF]

open access: yes, 2018
This thesis seeks to distinguish the main environmental parameters controlling the growth of Lobelia dortmanna and, by consideration of field conditions, describe which of these controls is most important in determining the zonation of the species, both ...

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Worldwide Advances in Seismic Zonation

open access: yes, 1995
Seismic zonation is the process that integrates the hazard, policy, and built environments to produce maps that divide a geographic region into smaller areas or zones which can be used by community decision makers to answer the question, Where is the ...
