Artificial intelligence‐based prediction of cooling pipe system parameters for thermal field control and crack prevention in mass concrete structures

Abstract The pile cap of a bridge pier is susceptible to thermal cracking caused by heat generated during cement hydration at early ages. Although numerical and machine‐learning methods have been used to analyze the thermal behavior of mass concrete with cooling pipe systems (CPS...

Permeability effect on heat transfer and flow dynamics past two tandem 45°-inclined square cylinders

In this study, two-dimensional transitional flow and convective heat transfer past two tandem porous square cylinders inclined at 45° are numerically investigated using the lattice Boltzmann method (LBM) at a Reynolds number ( R e ) of 150 and a Prandtl number ( P r ) of 0.71 acr...

Seismic Response of Concrete Columns Reinforced with CFRP Bars and Spirals Under Near-Fault Ground Motions

Carbon-fiber-reinforced polymer (CFRP) reinforcement is a potential alternative to steel in corrosive environments. However, CFRP is elastic without ductility, and the seismic performance of CFRP-reinforced concrete (RC) columns is inadequately understood. This study characterize...

Beyond Surface Modulus: Shape-Aware Crack-Index Assessment of Mass Concrete Foundations Under Early-Age Thermal Stress

Abstract Early-age thermal cracking is a major serviceability and durability concern in mass-concrete foundations, especially under hot-weather construction conditions. Although surface modulus is widely used as a massivity descriptor, its ability to predict stress-based cracking...

Prefix-sum encoding for quantum annealing with application to haplotype inference

Quantum annealing promises advantages for combinatorial optimization, but current hardware remains limited by sparse qubit connectivity. Encoding constrained problems onto these devices typically requires auxiliary variables that introduce dense couplings, degrading performance....
