Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

Dynamic Pavement Distress Image Stitching Based on Fine-Grained Feature Matching

open access: yesJournal of Advanced Transportation, 2020
Camera-based pavement distress detection plays an important role in pavement maintenance. Duplicate collections for the same distress and multiple overlaps of defects are both practical problems that greatly affect the detection results.

Distress Detection in Road Pavements Using Neural Networks

open access: yes, 2021
Combining Computer Vision (CV) and Anomaly Detection (AD), there is a convergence of methodologies using convolutional layers in AD architectures, which we consider an innovation in the field. The main goal of this work is to present different Artificial Neural Networks (ANN) architectures, applying them to distress detection in road pavements and ...

Recognition of the Typical Distress in Concrete Pavement Based on GPR and 1D-CNN

open access: yesRemote Sensing, 2021
Ground-penetrating radar (GPR) signal recognition depends much on manual feature extraction. However, the complexity of radar detection signals leads to conventional intelligent algorithms lacking sufficient flexibility in concrete pavement detection ...

Automated Pavement Distress Detection, Classification and Measurement: A Review [PDF]

open access: yesInternational Journal of Advanced Computer Science and Applications, 2021
Road surface distress is an unavoidable situation due to age, vehicles overloading, temperature changes, etc. In the beginning, pavement maintenance actions took only place after having too much pavement damage, which leads to costly corrective actions.

GPU-enabled pavement distress image classification in real time [PDF]

open access: yes, 2016
Pavement assessment is a crucial process for the maintenance of municipal roads. However, the detection of pavement distress is usually performed either manually or offline, which is not only time-consuming and subjective, but also results in an enormous

EVALUATION PAVEMENT DISTRESSES USING PAVEMENT CONDITION INDEX [PDF]

open access: yes, 2011
Pavement deterioration is resulted by both environmental and structural causes. It is difficult to maintain the road on the same specification that was owned at the opening and problems start to appear represented in the pavement cracks, holes and ...
