Opportunistic sensing for road pavement monitoring [PDF]
, 2020 Road surface state monitoring is of main concern for road infrastructure owners. Hence dedicated measurement campaigns using laser scanning and image analysis are performed on a regular basis. Yet, this type of monitoring comes at a high labor cost

Secondary wind dispersal enhances long-distance dispersal of an invasive species in urban road corridors [PDF]
, 2011 Roads contribute to habitat fragmentation and function as dispersal barriers for many organisms. At the same time many nonnative plant species are associated with road systems, a relationship that has been explained by the availability of disturbed ...

Advanced Engineering Materials, EarlyView.Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Algorithm on Contourlet Domain in Detection of Road Cracks for Pavement Images
Journal of Algorithms & Computational Technology, 2013 In this paper we present a detection algorithm of road cracks in several directions and each layer for pavement images in contourlet domain. Firstly, a pavement image is converted to a grey-scale image which is decomposed by using contourlet transform ...

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
