As environmental concerns continue to grow, there is increasing interest in using natural fibers as sustainable alternatives to synthetic fibers in the production of geotextiles for soil reinforcement. Coir fiber is one such promising natural material. Compared with other natural fibers, coir fiber...

Optical techniques for information security have drawn a lot of attention in recent years. The development of cryptanalysis strategies will also have a positive promotion for the cryptosystems themselves. However, most of the present publications on cryptanalysis of optical cryptosystems are focusin...

The Doppler Asymmetric Spatial Heterodyne (DASH) spectrometer is a new type of high-resolution spectral measurement instrument that has received widespread attention in re-cent years. However, in previous ground experiments, laser sources were often used so that without exposing the premise and limi...

A novel compressive optical cryptosystem based on single-pixel imaging is proposed. By using random sparse sampling in the encryption process, the plaintext is encrypted and compressed into a noise-like intensity sequence. As a result, the ciphertext is much less than the plaintext in volume. For de...

A high capacity steganography based on optical phase-encoding and transport of intensity equation (TIE) is proposed. The secret image is phase-encoded and then attached a real-valued host image to form a complex light field, which diffracts a short distance and generate a slightly different complex...

A new phase retrieval technique in digital holographic microscopy (DHM) with three defocused holograms is proposed. Given the defocusing distance, the phase distributions of tested specimen can be reconstructed with a simple algebraic equation. We have deduced this equation in detail. To avoid the m...

In this study, a comprehensive experimental framework was developed to quantitatively characterize the pore structure of a deep coal-rock (DCR; reservoirs below [3000 m]) gas reservoir. Experimentally, petrological and mineral characteristics were determined by performing proximate analysis and scan...

A multiple-image encryption method that is based on a modified logistic map algorithm, compressive ghost imaging, and coordinate sampling is proposed. In the encryption process, random phase-only masks are first generated with the modified logistic map algorithm; multiple secret images are transform...

With the implementation of the C-strain vaccine, classical swine fever (CSF) has been under control in China, which is currently in a chronic atypical epidemic situation. African swine fever (ASF) emerged in China in 2018 and spread quickly across the country. It is presently occurring sporadically...
