Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Nutritional Efficiency of Eucalyptus Clones Under Water Stress

open access: yesRevista Brasileira de Ciência do Solo, 2017
Plant health and nutrition are strongly influenced by the availability of water. The objective of this study was to evaluate the different patterns of initial growth and nutritional efficiency of ten drought-stressed Eucalyptus clones.

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

On the Strong Secure Domination Number of a Graph

open access: yesMathematics
In this paper, we characterize trees with a strong secure domination number less than or equal to 4 and compute this parameter for certain classes of graphs.

Tree Transducers and Tree Compressions [PDF]

open access: yes, 2004
A tree can be compressed into a DAG by sharing common subtrees. The resulting DAG is at most exponentially smaller than the original tree. Consider an attribute grammar that generates trees as output. It is well known that, given an input tree s, a DAG representation of the corresponding output tree can be computed in time linear in the size of s.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Radioscopie des territoires en Afrique à travers l’arbre (Cameroun et Burkina Faso)

open access: yesProjets de Paysage, 2017
The research presented in this article concerns different regions in Cameroon and Burkina Faso. The apparent diversity of the areas masks a situation of total convergence concerning the central role of the tree in the landscape.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Les arbres de Tunis peuvent-ils devenir un patrimoine urbain ? Pour qui ? Pourquoi ?

open access: yesProjets de Paysage, 2012
For our case which is Tunis, we’ve been relied on in-situ observations and results of interviews with the citizens to attempt to define; first, the status of the tree of Tunis. Then, second, we do a few assumptions about the perception of the tree by the
