Study on Shrinkage Cracking Morphology of Cement Mortar with Different Nanoclay Particles under Restraint

open access: yesBuildings, 2022
In this paper, different types and particle sizes of nanoclay (nano-metakaolin—NMK—and nano-attapulgite—NMA—clay) were selected to study the effect of nanoclay on the properties of cement-based cementitious materials.

Effect of MDI Actuation Timing on Inhalation Dosimetry in a Human Respiratory Tract Model

open access: yesPharmaceuticals, 2022
Accurate knowledge of the delivery of locally acting drug products, such as metered-dose inhaler (MDI) formulations, to large and small airways is essential to develop reliable in vitro/in vivo correlations (IVIVCs). However, challenges exist in modeling

Distance-2-Dispersion: Dispersion with Further Constraints

open access: yes, 2023
The aim of the dispersion problem is to place a set of $k(\leq n)$ mobile robots in the nodes of an unknown graph consisting of $n$ nodes such that in the final configuration each node contains at most one robot, starting from any arbitrary initial configuration of the robots on the graph.

Rayleigh-Wave Dispersion Analysis and Inversion Based on the Rotation

open access: yesSensors, 2022
Rotational observation is essential for a comprehensive description of the ground motion, and can provide additional wave-field information. With respect to the three typical layered models in shallow engineering geology, under the assumption of linear ...
