A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Effect of nuclear motion on harmonic cutoff intensity of H2+ and D2+

open access: yes四川大学学报. 自然科学版, 2021
The intensity of harmonic cutoff region of H2+ and D2+ driven by different laser conditions has been studied theoretically. The results show that for the lower laser intensity case, the harmonic yield of H2+ is higher than that of D2+ when the shorter ...

Interference-Induced Phenomena in High-Order Harmonic Generation from Bulk Solids

open access: yesApplied Sciences, 2019
We consider a quantum mechanical model for the high-order harmonic generation in bulk solids. The bandgap is assumed to be considerably larger than the exciting photon energy.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical

Laser intensity effect on single-order harmonic enhancement

open access: yes四川大学学报. 自然科学版, 2020
Through the laser waveform control, the enhancement of the single-order harmonic can be achieved. Further, when the fundamental laser intensity is increased, the enhancement of the single-order harmonic is disappeared.

High-order Harmonic Generation

open access: yes, 2010
X-rays were observed for the first time by Wilhelm Conrad Rontgen in 1895 (Rontgen, 1895). During the first century since that great event X-rays were benefiting mostly from their spatial resolution capability. However, recently it was possible to take advantage also from their temporal resolution due to novel sources providing ultrashort bursts of ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Enhancement of a single-order harmonic via laser waveform control

open access: yes四川大学学报. 自然科学版, 2020
Through controlling the laser waveform of the two-color field, the selective enhancement of single-order harmonic is obtained theoretically. The theoretical analyses show that the selective enhancement of single-order harmonic is attributed to the folded
