Despite the extensive applications of deep neural networks in data modeling filed, there are still some obvious deficiencies for the implementation in modern industrial cases. There are mainly reflected in the following aspects: first, the architectures are difficult to configure;second, the modeling process is time-consuming;third, the training procedure easily falls into the local optimum situation. To overcome these problems, exploring the nonconnectionist learning model has become a popular topic recently. This article proposes a deep nonconnectionist learning model based on kernel principal component regression (KPCR), which is referred to as stacked KPCR (SKPCR). By stacking multiple KPCR modules, a multilayer learning model is constructed by adopting hierarchical feature extraction. In SKPCR, the model structure is determined incrementally and there is only one parameter needed to be configured for each layer. Furthermore, an enhanced learning strategy is designed for alleviating the information loss problem in the training process. An actual industrial case is used to validate the effectiveness, including the prediction performance and modeling efficiency, of our proposed method. © 2024 IEEE.

Trioxane (Tox) is an important source of anhydrous formaldehyde, which is used in large quantities in industrial production resulting in large quantities of low concentration Tox wastewater. Liquid-liquid extraction is one of the commonly used methods for wastewater resource recycling. This study presents a method on the separation of Tox from wastewater using hydrophobic deep eutectic solvents (HDES). Firstly, Thy-BA and Thy-DA were screened from 12 HDES by extraction performance and solubility in water. The effects of different molar ratios of HDES, extraction temperature and addition of acetic acid as impurity on the extraction performance were further investigated. For the measured ternary phase data of HDES-Tox-water, the reliability of the data was verified using the Othmer-Tobias and Hand equations, and the data were fitted using the NRTL model. Quantum chemistry was used to calculate the interaction energy of HDES with Tox and to establish a correlation with the extraction efficiency. Hydrogen bonding was found to be the main force for separating Tox by electrostatic potential and interaction region indicator analysis. Molecular dynamics computing found that Thy was a substance that plays a major role in Thy-BA and Thy-DA. Ultimately, it was discovered that the chosen HDES has great recycling and thermal stability characteristics. This work explores three aspects of phase equilibrium, thermodynamics and microscopic separation mechanism revelation to support the systematic recovery of Tox wastewater. © 2025 Elsevier B.V.

IEEE Transactions on Artificial Intelligence 2022年第3期3卷 470-484页

With the rapid development of information technology, intelligent upgrading of the manufacturing industry has broken the closed environment of traditional industrial control systems (ICS);thus, the information security of ICS has been seriously threatened. As part of ICS, the process monitoring system (PMS) is heavily subject to external risks. Data-driven PMSs have been widely used as initial lines of defense to ensure ICS safety. Once the PMS is under attack, the consequences on the whole ICS will be unimaginable. Unfortunately, the safety issues of the PMS have received inadequate attention. This article reveals PMS's vulnerabilities through effective attacks. A novel method called subspace transfer network (STN) is proposed to conduct adversarial and poisoning attacks on the PMS simultaneously. Then the attack task flow is defined and explained to make online adversarial attacks and data poisoning on PMS. Meanwhile, aiming at two poisoning goals, targeted and untargeted attacks of STN are designed, respectively. Finally, the PMS's fragility is verified in two industrial benchmarks. © 2020 IEEE.

Nowadays, it is necessary to explore efficient antibacterial materials to complement or substitute the conventional antibiotic, to cope with the ever-growing bacterial contamination. Here, a series of Cu-doped ZIF-8 materials are prepared and adopted for disinfection against typical bacteria E. coli and S. aureus in dark. The results show that 5-7 log efficiency can be achieved at a dosage of 15-30 mg mL-1 of 1.35 atomic % Cu doped ZIF-8, and this concentration is also safe as verified by cytotoxicity test. Mechanism investigation shows that Cu(II) is reduced to Cu(I), which would contribute to the effective electron transfer for the reactive oxygen species generation. And these reactive oxygen species would cause oxidative stress and membrane damage on bacteria cells. All these results show the promise of Cu-doped ZIF-8 in the antibacterial applications especially in the environments without any energy input. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference Program and Proceedings.
