Zn is a toxic heavy metal that seriously endangers human health and ecological stability. For long time, traditional remediation techniques have been used to remediate Zn-contaminated soil prone other problems such as secondary contamination. In recent years, due the great danger posed by pollution, there has an increasing interest in applying eco-friendly sustainable methods soil. Therefore, this study, microbially induced calcium carbonate precipitation (MICP) technology was bioremediate...

Tropical cyclone intensity estimation is important to catastrophic weather forecast. In this paper, it treated as a classification task, with the categories class labels. Normally, traditional supervised methods require large amount of prior knowledge for training. However, in reality, only small labeled samples can be available. Therefore, paper proposes novel semisupervised deep learning framework based on convolutional neural networks (CNNs) FY-4 multispectral images (MSI). The new model...
