Optimizing Lightweight Geopolymer Concrete Mixes

Journal of Engineering and Applied Science
Abstract The development of geopolymer concrete is advancing rapidly worldwide. However, issues related to workability and setting time in geopolymer mixes, compared to traditional concrete mixtures, remain a challenge. These problems could be particularly concerning if geopolymer is used for masonry applications.

Residual Neural Network Compensation of Temperature‐Induced Gamma Shift in OLED Display

Journal of the Society for Information Display, EarlyView.
The figure summarizes the proposed white‐only sensing framework and highlights its key advantages in improving color accuracy and reducing calibration time ABSTRACT Organic light‐emitting diode (OLED) displays exhibit temperature‐induced chromatic shifts and luminance‐dependent nonlinear responses, causing CIEDE2000 color difference (ΔE) and local ...

Finite element modelling of shear connection for steel-concrete composite girders [PDF]

, 2002
The main objective of this thesis is to develop effective 3-dimensional finite element models to trace the behaviour of headed stud shear connectors in composite girders with solid slabs and precast hollow core slabs.

Dual Pathways of Loneliness in the Marketplace: Emotional Attachment, Empowerment, and Evaluations of Brand Warmth and Brand Competence

Psychology &Marketing, EarlyView.
ABSTRACT Loneliness shapes consumer behavior, yet whether it increases preference for warm or competent brands remains unresolved. We argue that this question cannot be answered without distinguishing who is perceived to be lonely. Individual loneliness, which is a person's subjective experience of social disconnection, activates agency‐restoration ...

DeepSeek‐Lattice‐KG: A Compact Language Model With Knowledge Graph Augmentation for Lattice Structure Design

Materials Genome Engineering Advances, EarlyView.
DeepSeek‐Lattice‐KG integrates a domain‐adapted 14B LLM with a Neo4j lattice knowledge graph distilled from 50,000 papers. It analyzes queries, retrieves supporting subgraphs, and generates grounded answers; on a 2100‐question, six‐domain benchmark, it achieves 94.8% accuracy.

Polymaterial Lattice Discrete Particle Model for the Optimization of Lightweight Aggregate Concrete: Intragranular Fracture and Compression Behavior

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.

Finite element modelling of nonlinear behaviour of headed stud shear connectors in foamed and lightweight aggregate concrete

, 2013
Composite steel-concrete construction is used widely due to its ability to utilise the concrete's compressive strength and steel's tensile strength to increase the span to depth ratio, reduced deflections and higher stiffness ratio than traditional steel
