Development of sustainable polymer composite with agro‐industrial residue for biomedical applications

open access: yesPolymer Engineering &Science, Volume 65, Issue 4, Page 1922-1933, April 2025.
Abstract The excessive use of plastics has raised significant environmental concerns, including harm to marine ecosystems and pollution. PLA, a widely used bioplastic, suffers from low toughness and thermal stability, limiting its industrial applications.

Impinging jet mixers: A review of their mixing characteristics, performance considerations, and applications

open access: yesAIChE Journal, Volume 71, Issue 1, January 2025.
Abstract Optimal control over fast chemical processes hinges on the achievement of rapid and effective mixing. Impinging jet mixers are a unique class of passive mixing devices renowned for their exceptional ability to achieve rapid mixing at micro‐length scales, whilst offering the possibility of a high throughput.

Technical Evaluation Report for Symposium AVT-147: Computational Uncertainty in Military Vehicle Design [PDF]

open access: yes, 2007
The complexity of modern military systems, as well as the cost and difficulty associated with experimentally verifying system and subsystem design makes the use of high-fidelity based simulation a future alternative for design and development.

Plausible Reasoning and Spatial‐Statistical Theory: A Critique of Recent Writings on “Spatial Confounding”

open access: yesGeographical Analysis, Volume 57, Issue 1, Page 152-172, January 2025.
Statistical research on correlation with spatial data dates at least to Student's (W. S. Gosset's) 1914 paper on “the elimination of spurious correlation due to position in time and space.” Since 1968, much of this work has been organized around the concept of spatial autocorrelation (SA).

Dynamics, Monitoring, and Forecasting of Tephra in the Atmosphere

open access: yesReviews of Geophysics, Volume 62, Issue 4, December 2024.
Abstract Explosive volcanic eruptions inject hot mixtures of solid particles (tephra) and gasses into the atmosphere. Entraining ambient air, these mixtures can form plumes rising tens of kilometers until they spread laterally, forming umbrella clouds. While the largest clasts tend to settle in proximity to the volcano, the smallest fragments, commonly

Globally simple Heffter arrays and orthogonal cyclic cycle decompositions

open access: yes, 2018
In this paper we introduce a particular class of Heffter arrays, called globally simple Heffter arrays, whose existence gives at once orthogonal cyclic cycle decompositions of the complete graph and of the cocktail party graph.

Implementing the MOLS table for n up to 500 [PDF]

open access: yes
Latin squares are an essential tool in the construction of combinatorial designs. Optimal solutions for problems such as scheduling problems and permutation arrays for powerline communication rely on the ability to construct sets of mutually orthogonal ...
