Alkali-silica Reaction and Alkali-carbonate Reaction

Tang Mingshu

Strategic Study of CAE 2000, Volume 2, Issue 1, Pages 34-40

Abstract:

Alkali-aggregate reaction (AAR) may be divided into two kinds： alkali-silica reaction (ASR) and alkali-carbonateThe chemical reaction between the reactive aggregate and alkali causes serious expansion and resultsFor ASR, the prime essential is the crystallinity of silica, which causes the rocks to display alkalicryptocrystalline, microcrystalline, glassy and strained silica, cristobalite, tridymite, etc. display high alkali

Turbidity-adaptive underwater image enhancement method using image fusion

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 3, doi: 10.1007/s11465-021-0669-8

Abstract: Clear, correct imaging is a prerequisite for underwater operations. In real freshwater environment including rivers and lakes, the water bodies are usually turbid and dynamic, which brings extra troubles to quality of imaging due to color deviation and suspended particulate. Most of the existing underwater imaging methods focus on relatively clear underwater environment, it is uncertain that if those methods can work well in turbid and dynamic underwater environments. In this paper, we propose a turbidity-adaptive underwater image enhancement method. To deal with attenuation and scattering of varying degree, the turbidity is detected by the histogram of images. Based on the detection result, different image enhancement strategies are designed to deal with the problem of color deviation and blurring. The proposed method is verified by an underwater image dataset captured in real underwater environment. The result is evaluated by image metrics including structure similarity index measure, underwater color image quality evaluation metric, and speeded-up robust features. Test results exhibit that the method can correct the color deviation and improve the quality of underwater images.
