A formulation for asphalt concrete air void during service life by adopting a hybrid evolutionary polynomial regression and multi-gene genetic programming

Scientific Reports
Bitumen, aggregate, and air void (VA) are the three primary ingredients of asphalt concrete. VA changes over time as a function of four factors: traffic loads and repetitions, environmental regimes, compaction, and asphalt mix composition.

Spherical void formers in concrete slabs

Journal of the South African Institution of Civil Engineers, 2010
Large span concrete flat-slab systems with internal spherical void formers (SVF) have been used in Europe for over a decade. They are bi-axially reinforced concrete flat-slab systems with a grid of internal spherical void formers.

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Direct Shear Behavior of Fiber Reinforced Concrete Elements

Journal of Engineering, 2018
Improving the accuracy of load-deformation behavior, failure mode, and ultimate load capacity for reinforced concrete members subjected to in-plane loadings such as corbels, wall to foundation connections and panels need shear strength behavior to be ...

Replacement of Waste Rubber for COA RSE Aggregate in LEGO (Interlocking Blocks)

International Journal of Advanced Research in Science, Communication and Technology
This invention relates to the development of sustainable LEGO-type interlocking construction blocks inspired by toy LEGO bricks. These blocks are designed to provide fast, modular, and eco-friendly construction. In this study, crumb rubber obtained from waste tyres is used as a partial replacement for coarse aggregates to promote sustainability and ...

Microporous Microgel Assemblies Facilitating the Recruitment and Osteogenic Differentiation of Progenitor Cells for Bone Regeneration

Advanced Functional Materials, EarlyView.
There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

World City Network Expansion 2000-2004. An appraisal of the determinants of connectivity growth among world cities [PDF]

The term “globalization” has long been vented indiscriminately everywhere with few being capable to either define or measure it. Cities are said to be at the forefront of the “works of globalization” by becoming coordinating centers for the transnational

Fermi Surface Nesting and Anomalous Hall Effect in Magnetically Frustrated Mn2PdIn

Advanced Functional Materials, EarlyView.
Mn2PdIn, a frustrated inverse Heusler alloy, showing electronic‐structure driven anomalous Hall effect with Weyl crossings, Fermi‐surface nesting and near‐zero magnetization ideal for low‐magnetization spintronics. Abstract Noncollinear magnets with near‐zero net magnetization and nontrivial bulk electronic topology hold significant promise for ...
