A Modular Designed Bolt Tightening Shaft Based on Adaptive Fuzzy Backstepping Control
Sibang Liu,Shuzhi Sam Ge,Zhongliang Tang 제어·로봇·시스템학회 2016 International Journal of Control, Automation, and Vol.14 No.4
This paper presents a modular designed autonomous bolt tightening shaft system with an adaptive fuzzybackstepping control approach developed for it. The bolt tightening shaft is designed for the autonomous bolttightening operation, which has huge potential for industry application. Due to the inherent nonlinear and uncertainproperties, the bolt tightening shaft and the bolt tightening process are mathematically modeled as an uncertain strictfeedback system. With the adaptive backstepping and approximation property of fuzzy logic system, the controlleris recursively designed. Based on the Lyapunov stability theorem, all signals in the closed-loop system are proved tobe uniformly ultimately bounded and the torque tracking error exponentially converges to a small residue. And theeffectiveness and performance of the proposed autonomous system are verified by the simulation and experimentresults on the bolt tightening shaft system.

Experimental study of frost growth on a horizontal cold surface under forced convection
Lingyan Huang,Zhongliang Liu,Yaomin Liu,Yujun Gou 대한기계학회 2010 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.24 No.7
Frost formation on a horizontal copper surface under low air temperature and forced convection conditions is investigated experimentally. Both the frost crystals pattern and the frost layer thickness formed on the cold plate are compared under different experimental conditions. The environmental variables considered in this study include the ambient temperature (T∞), air relative humidity (φ ), and velocity (v), as well as the cold surface temperature (Tw). The tested ranges are -5≤T∞≤5 °C, 50%≤φ ≤80%, 2.2≤v≤8.0 m/s, -16.8≤Tw≤-25.5 °C. The experimental results show the cold surface temperature and the air relative humidity have obvious effects on the frost growth: the frost layer thickness increases strongly with the decreasing cold surface temperature and increasing air relative humidity. The air temperature and air velocity or Reynolds number are also important factors affecting the frost crystals’ growth and thickness. With the increase of the air temperature and velocity, the frost crystals become denser, and the frost layer thickness become thicker, but this trend becomes weaker under higher air temperature and velocity.

The “Container-Cloud” Architecture and Scene Perception in IoE Era
Bo Yu,Zhongliang Guan,Yan Jiang,Cuiyu Qi,Shifeng Liu 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.5
This paper introduces a new innovative mobile application architecture called "Container-Cloud", which could be probably an inevitable trend in complex cloud, connected devices and network ecosystem in IoE(Internet of Everything) era. The significance of C-C is comparably to Java for web, and android for mobile. There are some innovations in platform operations, in service operations, in developing and in use. The "Container-Cloud" architecture can solve those application silo, enable applications developed, debugged and deployed transparently in cloud, allows mobile applications to be generated on demand, and be migrated and scheduled automatically among cloud, and creates an opportunity for implementation of "context-aware" application in cloud. The paper also gives some "context-aware" application examples based on C-C support in IoE era.

Generative Linguistic Steganography: A Comprehensive Review
Lingyun Xiang,Rong Wang,Zhongliang Yang,Yuling Liu 한국인터넷정보학회 2022 KSII Transactions on Internet and Information Syst Vol.16 No.3
Text steganography is one of the most imminent and promising research interests in the information security field. With the unprecedented success of the neural network and natural language processing (NLP), the last years have seen a surge of research on generative linguistic steganography (GLS). This paper provides a thorough and comprehensive review to summarize the existing key contributions, and creates a novel taxonomy for GLS according to NLP techniques and steganographic encoding algorithm, then summarizes the characteristics of generative linguistic steganographic methods properly to analyze the relationship and difference between each type of them. Meanwhile, this paper also comprehensively introduces and analyzes several evaluation metrics to evaluate the performance of GLS from diverse perspective. Finally, this paper concludes the future research work, which is more conducive to the follow-up research and innovation of researchers.

Objective: Vanin-1 (VNN1) is a pantetheinase that catalyses the hydrolysis of pantetheine to produce pantothenic acid and cysteamine. Our previous studies have shown that the VNN1 is specifically expressed in chicken liver which negatively regulated by microRNA-122. However, the functions of the VNN1 in lipid metabolism in chicken liver haven’t been elucidated. Methods: First, we detected the VNN1 mRNA expression in 4-week chickens which were fasted 24 hours. Next, knocked out VNN1 via CRISPR/Cas9 system in the chicken Leghorn Male Hepatoma cell line. Detected the lipid deposition via oil red staining and analysis the content of triglycerides (TG), low-density lipoprotein-C (LDL-C), and highdensity lipoprotein-C (HDL-C) after VNN1 knockout in Leghorn Male Hepatoma cell line. Then we captured various differentially expressed genes (DEGs) between VNN1- modified LMH cells and original LMH cells by RNA-seq. Results: Firstly, fasting-induced expression of VNN1. Meanwhile, we successfully used the CRISPR/Cas9 system to achieve targeted mutations of the VNN1 in the chicken LMH cell line. Moreover, the expression level of VNN1 mRNA in LMH-KO-VNN1 cells decreased compared with that in the wild-type LMH cells (p<0.0001). Compared with control, lipid deposition was decreased after knockout VNN1 via oil red staining, meanwhile, the contents of TG and LDL-C were significantly reduced, and the content of HDL-C was increased in LMH-KO-VNN1 cells. Transcriptome sequencing showed that there were 1,335 DEGs between LMH-KO-VNN1 cells and original LMH cells. Of these DEGs, 431 were upregulated, and 904 were downregulated. Gene ontology analyses of all DEGs showed that the lipid metabolism-related pathways, such as fatty acid biosynthesis and long-chain fatty acid biosynthesis, were enriched. KEGG pathway analyses showed that “lipid metabolism pathway”, “energy metabolism”, and “carbohydrate metabolism” were enriched. A total of 76 DEGs were involved in these pathways, of which 29 genes were upregulated (such as cytochrome P450 family 7 subfamily A member 1, ELOVL fatty acid elongase 2, and apolipoprotein A4) and 47 genes were downregulated (such as phosphoenolpyruvate carboxykinase 1) by VNN1 knockout in the LMH cells. Conclusion: These results suggest that VNN1 plays an important role in coordinating lipid metabolism in the chicken liver.
