Synthesis and characterization of TeO2-B2O3-CaO-ZnO glass systems for improved radiation shielding performance

open access: yesJournal of Radiation Research and Applied Sciences
This study aims to develop glass materials with enhanced radiation shielding properties with better attenuation performance by combining B2O3-TeO2-ZnO-CaO glasses with a fixed TeO2 content and varying concentrations of B2O3, ZnO, and CaO.

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

The investigation of tube sampling disturbance using transparent soil and particle image velocimetry [PDF]

open access: yes
A small-scale physical modelling system was developed and employed to investigate the effects of tube sampling. Amorphous silica and an oil blend of matching refractive index were mixed to form a transparent soil.

SAMPLE PATH OPTIMAL POLICIES FOR SERIAL LINES WITH FLEXIBLE WORKERS [PDF]

open access: yes, 2012
We study the dynamic assignment of cross-trained workers in serial production lines characterized by stochastic process times and inventory buffers between stations. Throughput maximization is the objective.

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

open access: yesAdvanced Engineering Materials, EarlyView.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...

Study on the mechanical properties of multi-walled carbon nanotubes-basalt fiber reinforced lunar soil simulant

open access: yes矿业科学学报
The utilization of in-situ lunar resources has become the core path for the construction of lunar scientific research stations. This paper adds multi-walled cabon nanotbes (MWCNTs) and basalt fibers (BF) into basalt-simulated lunar soil to study the ...

Possible sample paths of self-similar [alpha]-stable processes [PDF]

open access: yes
We describe all possibilities for sample path properties of H-self-similar [alpha]-stable processes with stationary increments for all pairs ([alpha], H), completing the picture presented by Kôno and Maejima (1991).Stable processes self-similarity sample

Finite Sample Bounds and Path Selection for Sequential Monte Carlo [PDF]

open access: yes, 2018
Sequential Monte Carlo (SMC) samplers have received attention as an alternative to Markov chain Monte Carlo for Bayesian inference problems due to their strong empirical performance on difficult multimodal problems, natural synergy with parallel ...

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 ...

Nondestructive Testing of Welded Composite Metal Foams

open access: yesAdvanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
