Adaptive Control and Synchronization of a New Uncertain Hyperchaotic Lorenz System Based on Parameter Identification

International Forum on Information Technology and Applications (2009)

Shuhua Wang Huaishan Liu Kai Cui

In this paper, the problems of control and synchronization of a new hyperchaotic Lorenz system with uncertain parameters are studied. Based on the Lyapunov stability theory and the adaptive control theory, this new uncertain hyperchaotic Lorenz system is suppressed to its unstable equilibrium. Furthermore, synchronization between two identical uncertain hyperchaotic systems is achieved by proposing an adaptive control law and a parameter estimation update law. Numerical simulations are presented to demonstrate the analytical results.

A Supervised Learning Approach for Accurate Modeling of CO₂–Brine Interfacial Tension with Application in Identifying the Optimum Sequestration Depth in Saline Aquifers

Energy & Fuels (2020)

Jiyuan Zhang Qihong Feng Xianmin Zhang Chenglong Shu Shuhua Wang

The CO2–brine interfacial tension (IFT) is a key parameter affecting the CO2 storage capacity in saline aquifers and therefore should be accurately characterized to ensure the optimal design of CO2 sequestration projects. This paper proposed the use of the extreme gradient boosting (XGBoost) trees for the fast and accurate modeling of the CO2–brine IFT. Results show that the novel model is capable of not only estimating the IFT but also reproducing the underlying correlation between the IFT and each input variable with remarkably high accuracies. Statistical matrices and point-wise error analyses demonstrate that the new model outperforms previous machine learning (ML) methods significantly. The estimation model was then applied for determining the optimum CO2 sequestration depth in saline aquifers, which reveals that higher pressure and/or lower geothermal gradients result in a significant increase in the maximum structural trapping capacity that occurs at noticeably shallower formations.

3-D visualization technique and its application

Shuying Wang Huaishan Liu Shuhua Wang Siyou Tong Lei Xing

Based on the 3-D visualization technique, by adjusting the attribute value, color, transparency of seismic data, the energy segments of the 3-D seismic volume could be displayed three-dimensionally, which supplied the deficiency of the conventional interpretation which couldn't display the shape of the geologic bodies. In this paper, the principle and operation flows of the 3-D visualization technique were presented and its practical application in the seismic interpretation of an oil field was studied. Therefore, by using the 3-D visualization technique, the small faults of this area could be identified correctly and the development of sandstone bodies could be predicted, which could serve as some scientific basis for drilling deployment.

N-MORB和E-MORB数据挖掘——玄武岩判别图及洋中脊源区地幔性质的讨论

岩石学报 (2017)

王金荣 JinRong Wang 陈万峰 Wanfeng Chen Zhang Qi Zhang Qi

MORB分为N-MORB和E-MORB，二者的区分通常是以LREE亏损和富集为标志。玄武岩的基本理论主要是在MORB研究成果的基础上建立起来的。通常认为，N-MORB和OIB是两个独立的端元，E-MORB是N-MORB与OIB不同程度混合形成的。在20世纪70~80年代，玄武岩构造环境判别图的建立极大促进了玄武岩在地球动力学及大地构造背景研究的进展，其方法应用持续盛行了几十年。然而，国外学者现在已逐渐淡化玄武岩判别图解的应用，但在中国仍有方兴未艾之势。本文利用PetDB数据库5万多个MORB数据的投图表明，全体样品投图的效果显然比抽样和典型样品得出的结果更扎实可靠，许多原先被广泛应用的主量、微量元素判别图无论从实践上还是理论上均存在一些问题。本文的研究结果进一步表明，MORB样品既有LREE亏损的，又有富集的，但亏损和富集程度与早先定义的差异较大，揭示了洋脊下地幔不均一性要比早先认识的更为复杂，成分范围变化更大，仅少数是强烈亏损的，部分可能是相当富集，甚至可以与OIB源区相类比；玄武岩构造环境判别图需要重新审视，基于岩浆成因机理的多维度、高置信度的判别体系有待于建立。

Exploitation and sustainable development of tourism in Mount Songshan World Geopark

Guotu yu ziran ziyuan yanjiu (2009)

Shuhua Wang

there are complex and varied geological tourist resources in Mount Songshan World Geoparks. Songshan World Geopark, which are very typical, rare, natural, systematic and complete. It is an exciting tourist attraction. This paper gives a systematic analysis to the existing problems at present in Songshan geological tourism development,and puts forward the countermeasures such as making scientific planning, highlighting the features of the geological tourist attractions,improving the geopark interpretation system,perfecting the related laws and regulations, strengthening the protection of geological tourism resources; promoting the propaganda work and creating a geological tourism marketing network system and rationalizing the Songshan tourism management system.
