Crack initiation and failure of block-in-matrix rocks under Brazilian test using digital image correlation

Theoretical and Applied Fracture Mechanics, 2020
Bimrocks feature stiff blocks randomly distributed in a soft matrix. Despite their wide distribution in nature, their significant effects on the failure of rock structures such as slopes, mines and tunnels have not been fully understood.

Multi-scale digital image correlation for detection and quantification of matrix cracks in carbon fiber composite laminates in the absence and presence of voids controlled by the cure cycle

Composites Part B: Engineering, 2018
Digital image correlation is applied to the images of a deforming composite to obtain strain maps at three length scales: micro-scale (ply level, hundreds of micrometers), meso-scale (laminate level, millimeters), and macro-scale (specimen level, tens of

Background-free room temperature phosphorescence and digital image colorimetry detection of melamine by carbon nitride quantum dots in cellulose matrix with smartphone-based portable device.

Food Chemistry, 2022
Carbon nitride quantum dots (CNQDs) were embedded in the sodium carboxymethyl cellulose (CMC) matrix to form CNQDs-CMC film to explore the room temperature phosphorescence (RTP) of CNQDs, which suppress the non-radiative relaxation process due to the ...

Securing Digital Images using Stream Cipher and MDS Matrix

SN Computer Science, 2021
This is an improved and extended version of the paper presented in CVIP 2020 conference. Stream ciphers are extensively used over a wide range of applications including security of digital data. In this paper, a method for securing different types of images (binary, gray scale, true color, and index) based on stream cipher (RC4A) and MDS (Maximum ...

Digital image encryption algorithm through unimodular matrix and logistic map using Python

, 2021
Hill Cipher is one of the methods used in Cryptography. In the Hill Cipher algorithm, the key square matrix must have an inverse modulo. One special matrix that definitely has an inverse is the unimodular matrix.

Scattering matrix tomography: deep imaging with digital gates

Optica Imaging Congress (3D, COSI, DH, FLatOptics, IS, pcAOP), 2023
Light scattering in opaque materials limits the imaging depth. We present a non-invasive method that uses hyperspectral scattering matrices to realize virtual spatiotemporal focusing, enabling deep tomography with sub-micron resolution and large depth of field.
