Pavement Cracking Detection using an Anisotropy Measurement [PDF]
Computer Graphics and Imaging, 2010 Automatic pavement cracking detection is a part of road maintenance and rehabilitation strategies. Cracks detection is one of the main features used by road authorities to manage efficiently its networks. Different systems are available to perform road analysis. We give a short description of some of them. Apparatus which was used to provide our images

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 ...

Determining the relationship between rock colour and the type of physical weathering on desert pavements in arid landscapes, Ras Al Khaimah, UAE [PDF]
, 2008 Despite opposition to the theory that diurnal heat fluxes within desert rocks cause enough internal stress to form cracks on clasts leading to the break down of the desert material, this study provides further evidence that this is a credible process in ...

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Advanced Functional Materials, EarlyView.Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

Advanced Functional Materials, EarlyView.Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.
