Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

open access: yesEnergy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

New Operations on Interval Neutrosophic Sets

open access: yesJournal of New Theory, 2015
An interval neutrosophic set is an instance of a neutrosophic set, which can be used in real scientific and engineering. In this paper, three new operations on interval neutrosophic sets based on the arithmetic mean, geometrical mean, and respectively ...

Experimental Investigation on Steam Generation Performance of a Solid Thermal Storage‐Based Steam Production System

open access: yesEnergy Science &Engineering, EarlyView.
1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

open access: yesEnergy Science &Engineering, EarlyView.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

HRR–Time Behaviour of Untreated Wood Under SBI Conditions: Implications for the Interpretation of FIGRA and THR600

open access: yesFire and Materials, EarlyView.
ABSTRACT Reaction‐to‐fire classification of wood‐based materials in Europe relies on SBI‐derived parameters such as FIGRA and THR600. While these parameters provide a robust and practical basis for classification, their relationship to the underlying HRR–time development remains difficult to interpret.

Exact Computation of the Color Function for Triangular Element Interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We propose a robust algorithm, the Front2VOF algorithm, to compute the color function for triangular element interfaces in Front‐Tracking methods on a Cartesian mesh. ABSTRACT The calculation of the volume enclosed by curved surfaces discretized into triangular elements and a cube is of great importance in different domains, such as computer graphics ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Materials and Music: Selective Imperfection as a Generative Framework for Analysis, Creativity and Discovery

open access: yesInterdisciplinary Materials, EarlyView.
Vibrations in matter, from spider webs to molecules, water to flames, share a grammar with music. We propose that creativity emerges when constraints force expansion beyond existing possibilities. Selective imperfection restores balance, enabling invention.
