Predicting Dissolution Kinetics of Tricalcium Silicate Using Deep Learning and Analytical Models

open access: yesAlgorithms, 2022
The dissolution kinetics of Portland cement is a critical factor in controlling the hydration reaction and improving the performance of concrete. Tricalcium silicate (C3S), the primary phase in Portland cement, is known to have complex dissolution ...

Analytical results on the polymerisation random graph model [PDF]

open access: yes, 2017
The step-growth polymerisation of a mixture of arbitrary-functional monomers is viewed as a time-continuos random graph process with degree bounds that are not necessarily the same for different vertices.

Chandra ACIS-I particle background: an analytical model [PDF]

open access: yes, 2014
Aims: Imaging and spectroscopy of X-ray extended sources require a proper characterisation of a spatially unresolved background signal. This background includes sky and instrumental components, each of which are characterised by its proper spatial and ...

A Physics-Based Analytical Model for Current–Voltage Characteristics of Perovskite Solar Cells Incorporating Bulk Recombination

open access: yesEnergies, 2021
A physics-based compact analytical model for studying the current–voltage characteristics of perovskite solar cells has been proposed by considering the external voltage-dependent carrier transport, exponential photon absorption, and bulk charge carrier ...

Modeling and Testing for Slotted Disk Springs Considering Linearly Gradient Thickness and Friction

open access: yesApplied Sciences, 2023
The slotted disk spring has been widely used given its nonlinear characteristics. However, the number of studies on them is limited, and the influences of nonuniform thickness have not been investigated theoretically and experimentally. Additionally, the
